Introduction to the cooler, the composition of the cooling system

Choosing a cooler is key point 1There are many types of cooler models, which need to be decided according to the actual working conditions and applications. When Jiangsu Changsheng provides users with heat exchange solutions, it will carry out technical exchanges, such as when the flow rate is large and the pressure drop is small, you can choose the plate heat exchanger model with less resistance, and vice versa.

Especially when choosing a stainless steel plate type all-welded plate heat exchanger, it is necessary to carefully measure the temperature and other parameters, and try to meet the long-term stable trial of the appropriate model. 2.The selection of flow channel and process is a group of parallel flow channels in the same flow direction of a medium in the heat exchanger equipment, and similar plates constitute the flow channel of the medium.

The user can select the stream based on the calculation of the parameters....

The cooling process of the cooler is carried out in a vacuum-sealed state, which effectively avoids the secondary contamination of bacteria, which saves costs and ensures the safety and hygiene of food. Loop speed is solved.

The components of the cooling system include radiator, water pump, radiator electronic fan assembly, thermostat, water pump assembly, radiator kettle, radiator fan, radiator lower guard, radiator cover, radiator upper guard, thermostat round cover, water pump pulley, radiator blade, tee joint, radiator water temperature sensor, radiator air ring, water pipe, radiator net, radiator fan motor, left and right water pipes, radiator fan coupler, radiator bracket and temperature control. The working principle of the cooling system is divided into four sides:1

How the forced circulation of cooling water works. When the engine is working, the water pump is driven to work, and the water pump pressurizes the antifreeze into the water channel of the engine block. The water pump continuously squeezes the antifreeze into the tank, raises the water pressure, and sends it through the thermostat to the radiator outlet pipe.

2.In a forced circulation system, the amount of water pumped by the pump depends on the water line of the tandem thermostat. The water pump is installed in the inlet channel and the thermostat is installed in the outlet channel.

The water is pumped from the radiator to the water channel of the cylinder, and the thermostat regulates the size of the water flow. 3.Principle of temperature regulation:

When the engine is working, the water pump will inject antifreeze hydraulic pressure into the engine. During the circulating flow of antifreeze, heat is carried to the radiator, which radiates the heat into the atmosphere. 4.

The function of the thermostat is to make the engine heat up to the mechanical temperature required for normal operation in a short period of time by adjusting the size of the choke. When the engine starts cold, the thermostat closes the large and small flow circulation channels leading to the radiator, and only the small side cavity rubber runner water or bypass water flows on the thermostat, thereby limiting the circulation of cooling water, reducing the preheating time, and avoiding the phenomenon of too long preheating time.

Coolant is also known as antifreeze, mainly antifreeze, the freezing point of antifreeze in different regions is also different, followed by the boiling point, the normal water temperature of the engine is more than 80 degrees, and it will soon reach nearly 100 degrees in summer, the boiling point of antifreeze can reach 130 degrees, and finally it is anti-rust and anti-corrosion, and it is not easy to produce water quality! It is recommended to replace it in two years or 40,000 kilometers!

"Blue wolf" antifreeze "is engine coolant, which is an indispensable heat dissipation medium for the normal operation of automobile engines. The main function of antifreeze is to prevent the coolant from freezing and cracking the radiator and freezing the engine block or cover when parking in the cold winter, and when the temperature is high in summer, it can effectively prevent boiling and avoid boiling. Automobile antifreeze has a large effect, which directly affects the performance and service life of the car.

The function of the cooling system is to keep the engine at the right temperature (coolant temperature) to be moderately cooled in any operating condition.

The function of the pump is to pressurize the engine coolant and circulate it in the cooling system.

The function of the thermostat is to automatically change the flow rate of the radiator coolant according to the temperature of the engine coolant, so as to adjust the cooling intensity of the cooling system.

When the coolant temperature is lower than 80, the paraffin wax becomes a solid state, the spring presses the valve on the seat, the valve is closed, and the coolant flows through the bypass port to the air conditioner radiator inlet pipe without flowing into the radiator, that is, a small circulation is carried out, and the cooling intensity of the cooling system is small. When the temperature of the coolant is higher than 80, the paraffin wax melts into a liquid state, and its volume expands, forcing the rubber sleeve to shrink, the upper end of the reverse push rod can not move up because it is fixed, the rubber sleeve pushes the shell to overcome the elastic force of the spring and move downward, and the valve is opened, and most of the coolant can enter the radiator along the radiator inlet pipe for large circulation, and a small part of the coolant is still circulated for a small time, and the cooling intensity of the cooling system increases.

Cars are already a must-have tool for everyone to get around. Of course, automotive knowledge is essential. In order to facilitate everyone to understand this knowledge, today Bian Xiao will introduce to you this question about what the cooling system is composed of.

Interested friends can learn about it, it may be helpful to you.

Most of the water cooling systems used in automobiles are forced circulation water cooling systems, where water is forced to circulate through the cooling system through a water pump. The water cooling system consists of a water pump, radiator, cooling fan, thermostat, compensation barrel, water jacket in the engine block and cylinder head, and other accessories. The role of an automotive cooling system is to keep the engine in a moderate temperature range under all operating conditions.

The cooling system is to avoid both overheating and winter engine overheating. According to the different cooling mediums, the cooling system can be divided into air cooling and water cooling. If the positive heat of the sail from the high-temperature parts of the engine is directly dissipated into the atmosphere for cooling, this device is called an air cooling system.

A device that first transfers heat to the cooling water, and then cools it by dissipating the heat into the atmosphere, which is called a water cooling system. The water cooling system is widely used in automobile engines because of its uniform cooling, good effect, and low engine noise. 1.

Water pump: Pressurizes the antifreeze to ensure its circulation in the cooling system. Centrifugal water pumps are widely used in automobiles.

2.Radiator: It is composed of three parts: water inlet chamber, water outlet chamber and radiator core.

Antifreeze flows into the radiator core, and air flows out of the radiator core. The hot antifreeze gets cold because it radiates heat to the air, whereas the cold air gets hot because it absorbs the heat of the antifreeze, so the radiator is a heat exchanger. 3.

Cooling fan: When the fan rotates, it draws in air and passes it through the radiator, improving the heat dissipation capacity of the radiator and accelerating the cooling of the antifreeze. 4.

Thermostat: A valve that regulates the flow path of antifreeze. It opens or closes the antifreeze channel leading to the radiator depending on the temperature of the antifreeze.

5.Compensation barrel: when the antifreeze is heated and expanded, part of the antifreeze enters the compensation barrel; When the antifreeze cools, a portion of the antifreeze is sucked back into the radiator, so the antifreeze can't overflow.

It consists of a compressor, a condenser, a throttling part, and an evaporator.
