What is the cooling system of the car and what is the function of the water tank?

The cooling system includes the front fan, radiator, water tank, water pump, water pipe, water jacket in the engine, and a very important thermostat.

When the temperature of the engine is not high, the cooling water only goes through a small circulation, that is, the water does not pass through the thermostat and radiator, when the temperature of the water is high to a certain extent, the deformed metal in the thermostat is opened due to the high temperature, then the cooling water goes through a large circulation, through the radiator, of course, the lower the water temperature is better, but the water temperature is too low, such as in winter, it is possible to freeze the water in the cooling pipeline, so that the pipeline is blocked, especially in the thermostat, because it is a small metal device, it is easy to freeze, At this time, many people will add boiling water to ice to ensure the normal operation of the cooling system, here and the cooling system does not conflict, because the temperature of the engine is very high, up to a few, so even if boiling water is added, it can also play a good heat dissipation function, even if it is cold water, the entire cooling system is about to become boiling water after several times through the engine, so the effect is the same.

The temperature of the automobile engine should be kept at a suitable temperature as the human body temperature, which cannot be high or low, and the cooling system controls the temperature of the engine at a constant temperature range to the air conditioning of the automobile engine. Just like we use air conditioning in summer, you always use the air conditioner instead of the heat, but just adjust the temperature of the air conditioner. That's why it's called a "cooling system".

The water tank plays a role in regulation, everything has a relative temperature, and it is not negotiable to exceed a certain limit.

I don't know, do you have any understanding of the car modification all-aluminum water tank, these water tanks are thickened, the original car is generally 26mm, and the thickened type is 40mm or 65mm, if the off-road vehicle is thicker. If you know more about it, you can go to the Zhisai auto parts network to view.

The car condenser is not a water tank, they are two different parts, the condenser is the part inside the car air conditioning system. The water tank is the radiator of the automobile engine, commonly known as the radiator, which reduces the operating temperature of the engine through the continuous circulation of coolant.

The role of the condenser:

The function of the condenser is to dissipate heat and cool the refrigerant vapor discharged from the compressor at high temperature and high pressure, so that it can be condensed into liquid high-pressure refrigerant.

It is mainly to quickly transfer the heat in the pipe to the air near the pipe for heat dissipation, which belongs to the process of heat release, so the temperature of the condenser is generally relatively high.

Answer: 1. The car condenser and the water tank are not the same thing, they are two different parts of the car - (1) the car condenser is a heat dissipation part of the car air conditioning system;

2) And the automobile water tank is a heat dissipation component of the automobile engine cooling system.

2. The function of the automobile condenser is:

The high-temperature and high-pressure gaseous refrigerant pumped by the air conditioning compressor—

1) Heat dissipation; 2) Liquefaction.

It becomes a medium-temperature and high-pressure liquid refrigerant.

1. The automobile water pump is the main component of the automobile cooling system circulation. The engine rotates the water pump bearing and impeller through the pulley. The coolant in the water pump is then rotated together by the impeller.

Under the action of centrifugal force, it is thrown to the edge of the pump casing, so that the branch creates a certain pressure, and then flows out of the outlet or water pipe. As the coolant is thrown out, the pressure in the center of the impeller decreases. Under the action of the pressure difference between the inlet of the water pump and the center of the impeller, the coolant in the water tank is sucked into the impeller through the water pipe, so as to realize the reciprocating circulation of the coolant.

2. The purpose of automobile water pump. In the cylinder block of the automobile engine, there is a cooling water channel, which is connected to the radiator (commonly known as the water tank) at the front of the car through the water pipe, forming a large water circulation system. A water pump is installed at the upper outlet of the engine, which is driven by a fan belt to pump hot water out of the engine block waterway and at the same time pump in cold water.

There is also a thermostat next to the water pump. When the car is just started (cold car), it does not open, and the cooling water does not pass through the water tank, but only circulates in the engine (commonly known as small circulation). When the engine temperature reaches more than 80 degrees, it turns on, and the hot water in the engine is pumped into the water tank, and the cold air when the car moves forward blows through the water tank to take away the heat.

That's basically how it works.

Simply put, a water pump: a power mechanism that circulates a car's coolant from the engine to the water tank. If the pump is broken, the coolant will not circulate.

If the engine is still running and the water temperature is too high, it may cause the engine to pull the cylinder. It's troublesome. Therefore, it is best for drivers to get into the habit of looking at the car's gauge while driving, just as carefully as they see how much gasoline is left.

3. Failure of automobile cooling water pump - automobile water pump makes noise. The noise of the automobile water pump is generally caused by two reasons under the transportation type, and the elimination method is used to analyze as follows:

1) Whether it is caused by the water seal related parts, the key component of the water pump is the bearing, and the failure is mutual. If the structure of the water pump and the shaft connection bearing is well designed, it will not cause the eccentricity, leakage and abnormal sound of the water seal due to bearing wear (special attention: when the belt is assembled on the pulley after repairing the water), it must be assembled in accordance with the belt tension specified in the instruction manual, and the general car belt tension is 350-550N, which must be noted, otherwise the engine will be serious after a period of operation.

It is recommended to turn the bearing by hand to see if there is any stuckness. If not, it's a problem with the water seal design.

2) The design of the water seal structure is unreasonable. If so, it needs to be improved and the structure is progressive. In summary, the design rotation direction of the improved water seal should be consistent with the rotation direction of the water pump.

The function is to help the engine to cool down, to restore the temperature of the engine to normal values, and to make the power of the engine more stable. When there is a problem, the cooling water pump should be replaced immediately, so that the problem can be solved in time.

Cooling, avoiding the temperature rise, more dispersed to let the disturbing vehicle drive, there is a problem, must be repaired, determine what the problem is, so that it can be solved.

It has a particularly important role, can achieve a particularly good sliding cooling effect, can ensure the temperature of the engine, and must solve the problem in time if there is a problem.

The main job of the cooling system is to dissipate heat into the air to prevent the engine from overheating, but the cooling system has other important roles. The engine in a car is operating optimally at the right high temperatures. If the engine gets colder, it will wear out components faster, making the engine less efficient and emitting more pollutants.

Therefore, another important role of the cooling system is to heat up the engine as quickly as possible and keep it at a constant temperature. The fuel burns continuously inside the engine of the car. Most of the heat generated during combustion is removed from the exhaust system, but some of the heat is still trapped in the engine, allowing it to heat up.

When the coolant temperature is about 93, the engine is running optimally. At this temperature: the combustion chamber is hot enough for the fuel to evaporate completely, so that the fuel can be better burned and gas emissions can be reduced.

If the oil used to lubricate the engine is thinner and less viscous, the engine parts can operate more flexibly, the engine will use less energy as it rotates around its own parts, and the metal parts will be less susceptible to wear.

The purpose of the cooling system is to keep the engine within the proper temperature range under all operating conditions. The cooling system is designed to prevent both the engine from overheating and the engine from overcooling in winter.

The cooling system can be divided into air cooling and water cooling according to different cooling media. If the heat of the high-temperature parts of the engine is directly dissipated into the atmosphere and cooled, it is called an air-cooled system.

A device that transfers this heat to the cooling water and then dissipates it into the atmosphere for cooling is called a water-cooling system. Due to the uniform cooling of the water cooling system, the good effect, and the low noise of the engine operation, the water cooling system is widely used in automobile engines at present.

The main function of the automobile cooling system is to ensure that the temperature of the car is kept within a certain range during the driving process, so as to achieve a safer and scientific driving effect and requirements.

1. The engine is overheating.

Air bubbles: The air in the antifreeze produces a lot of foam when agitated by the water pump, which can prevent the water jacket wall from dissipating heat.

Scale: The calcium and magnesium ions in the water will slowly form scale after a certain high temperature, which greatly reduces the heat dissipation capacity. At the same time, it will also cause local blockages of waterways and pipelines, and the antifreeze cannot flow normally.

Hazards: The engine parts are heated and expanded, which destroys the normal fit clearance, affects the cylinder inflation, decreases the power, and reduces the oil lubrication effect.

2. Corrosion and leakage.

Ethylene glycol is highly corrosive to the water tank. And with the failure of antifreeze preservatives. Corrosion of radiators, water jackets, pumps, pipelines and other parts.

1. Cooling system coolant: (1) Radiator crack or perforation leakage. The water jacket of the cylinder block is damaged, causing the cooling water to be lost. (2) Broken and leakage of inlet and outlet pipes. (3) The switch is damaged and leaking.

Maintenance method: (1) Use anti-leakage agent to stop leakage, if there is serious water leakage, the radiator should be replaced. (2) If the water pipe is cracked and aged, it should be replaced with a new part. (3) If the switch is damaged and the coolant leaks, the switch should be replaced.

2. The engine coolant temperature is too high, the reasons: (1) The cooling water is not enough. (2) The fan transmission belt is broken or adjusted too loosely, and the cooling effect disappears or weakens.

3) There is more scale in the water jacket and radiator of the cylinder block, and the heat dissipation performance is reduced. (4) The pump is not working properly, and the water circulation is not smooth. (5) The radiator fins are poured or connected to the hose to suction and deflat.

6) The water temperature gauge and sensor are invalid.

Troubleshooting method: (1) Add cooling water in time, and repair if the radiator leaks. (2) Adjust the tightness of the fan drive belt or replace it with a new drive belt.

3) Clean the cooling system to remove scale. (4) Overhaul or replace the water pump. (5) Check the water outlet pipe, if the suction deflation should be eliminated, and repair the radiator heat sink.

6) Overhaul or replace water temperature gauge and sensor.

Cooling system accessories included:

Radiator, water pump, radiator electronic fan assembly, thermostat, water pump assembly, radiator water bottle, radiator lower guard plate, radiator cover, radiator upper guard plate, thermostat cover, water pump pulley, radiator fan blade, tee, radiator water temperature sensor, radiator air ring, radiator fan, water pipe, heat dissipation network, radiator fan motor, upper and lower water pipes, radiator fan coupler, radiator bracket, temperature control switch, etc.

Failures are all possible, which one do you want to fail???

Most tanks contain antifreeze instead of water, and the level should be kept between the lowest and the highest. If the level is below the minimum, antifreeze of the same brand and size should be added, and all antifreeze should be replaced if necessary. The key to choosing antifreeze is to base on the local minimum temperatures, most of which are all-weather temperatures in the plant.

Some friends use water instead in the summer. Not impossible, but not recommended.

What water is in the <> car water calendar box? Most tanks are filled with antifreeze, not water, which is coolant. The liquid level should be kept between the lowest and the highest.

If the level is below the minimum, antifreeze of the same brand and size should be added, and all antifreeze should be replaced if necessary. The key to choosing antifreeze is to base on the local minimum temperatures, most of which are all-weather temperatures in the plant. Some of you may think, "Can't you just fill your car's tank with water?

You can add water, but it is not recommended. Because long-term water filling can corrode the tank, remember not to add tap water. Because tap water is easy to form scale, scale is very harmful to cars, and its thermal conductivity is very small, it is 1 25 of cast iron, 1 50 of brass The conductivity of antifreeze decreases significantly, the engine temperature rises, and corrosion intensifies, which in turn promotes the increase of scale, which turns into a vicious circle after development.

Pay attention to the high temperature when filling the water tank in the car, so it is best to charge the water tank when the car is cold. Open the lid of the water tank or expansion pot (different models have different filler seats). If there is basically no water in the tank, you can add water first, then drive, slowly add water or water until the water overflows, and then tighten the lid.

At the same time, you can add some throttle valves to increase the water temperature. Before cooling the fan to work, when the fan stops, find a damp towel to cover it and open it slowly to see if it reaches the standard watermark line, if not enough, add to the bit.

Adding tap water to your car's water tank can change the quality of your coolant and make it not work properly. Special tank water or qualified antifreeze must be added to the car's fuel tank. The function of the water tank is to dissipate heat to the working engine to prevent mechanical overheating and metal expansion from affecting the work.

The full name of antifreeze is antifreeze, which means coolant with antifreeze function, which prevents the coolant from freezing and cracking the radiator when parking in the cold winter months, and freezing the engine block or engine cover. Antifreeze needs to be replaced regularly, and it is recommended that car owners replace it every 2 years. Many car owners think that antifreeze is only used in winter, but in reality, it should be used all year round.
