When the phone is charging, it is normal for the charger to heat up, because the internal components of the charger are very hot, and there is an electric current passing through during charging, and as time advances during the charging process, the electric energy will be converted into heat energy, causing it to heat up.

There are several reasons why the charger heats up:

The current intensity of the charger is very high, the connected data line current is very small, the transmission process is relatively slow, and the backlog over time will cause the charger to heat up.

The external ambient temperature, due to external reasons, causes the charger itself to be converted into heat energy when charging, and the external temperature is too high, which will cause the charger to heat up.

The volume of the charger, now on the market in order to facilitate carrying, the finished product of the charger is very small, in the charging process, the temperature of the components inside itself is very high, without changing the capacity, the volume becomes smaller, and the heat dissipation function will decrease, resulting in its heating.

Product quality problems, there are many copycat chargers on the market, and poor quality will cause slow charging, and the charger is easy to heat.

Solution to the heating of the charger:

Try to use the original charger to charge, the quality of the copycat version itself is not up to par, the high current of the internal components, and the high temperature is not handled well, and it is easy to have a safety accident.

Try to charge your phone in a cool environment, away from surrounding heat sources, such as: stoves, electric fans, etc., so as not to cause the ambient temperature to be high, the charger will be affected and hot, and it will be easy to heat up when charging.

Reduce the number of charger use, play less mobile phones, reduce the number of charges, and can not overcharge, generally speaking, it can be fully charged in about 3 hours, and the charger should be unplugged after being fully charged, which can not only reduce the excessive heating of the charger, but also extend the life of the charger.

Don't play with the phone when charging, try to charge it in a shutdown state, play with the phone when charging, while consuming power output, a charging input makes it easier to make the charger heat up, and it will also affect the life of the phone.

The charger is a power converter, which also has efficiency problems, and it also consumes energy while converting electrical energy, and the energy consumed is converted into heat.

1. When the mobile phone is charging, it is normal for the charger to heat up, which is related to the current intensity and ambient temperature of the charger output.

2. In addition to the current increase, the size of the charger is also a problem. The smaller the size of the charger, the worse the heat dissipation performance, the higher the requirements for electronic components, and the better in terms of withstand voltage and temperature.

3. The high temperature of the charger has a lot to do with the switch tube of the charger, if the specification of the switch tube is not high, then the current will pass through, and the heat will be more.

1. The mobile phone charger heating solution can not use the copycat charger 2, the mobile phone charger heating solution is charged in a cool environment 3, the mobile phone charger heating solution is not to play with the mobile phone when charging.

4. Do not overcharge the mobile phone charger heating solution. Unplug when it's full.

5. Be careful of the surrounding heat source of the mobile phone charger heating solution 6, and reduce the number of charging times of the mobile phone charger heating solution.

This is normal. Because the current of the mobile phone battery is many times greater when it is charged than when it is discharged, it will heat up, so the charging time is shorter.

It's a normal phenomenon of resistance heating, so don't worry.

When using high-power electrical appliances, the power is too large, and the cross-sectional area of the wire is small, the resistance value of the line is large, and the current produces a thermal effect when passing through the wire, and the heat generated will make the wire and socket hot and soft.

Electric current has a thermal effect, and when an electric current passes through a resistor, the current does work and consumes electrical energy, which produces heat.

The socket has a rated current and cannot be overloaded, otherwise the socket will heat up, damage the electrical appliances and even cause disasters. Pay special attention not to plug high-power household appliances such as air conditioners and microwave ovens into sockets with small rated current values.

When the socket is connected to high-power electrical appliances, it is necessary to pay attention to electrical safety, replace wires and sockets, or reduce the power, otherwise it will cause unsafe accidents.

This principle is very simple, first of all, no matter what the cross-sectional area of the wire is, it has resistance, if there is a current through it will be heated, the larger the current, the more powerful the heating Of course, when the designer designed this socket, it has its rated current For example, 16A So if the rated current of your electrical appliance exceeds this 16a, it will also exceed the current that the wire on the socket can carry The copper core of the wire is naturally hot, and the outer insulation layer will become soft at a certain temperature It can even cause a short circuit and other failures, and it would be much better if you could change to a wire with a larger cross-sectional area. That's basically what it looks like, and I hope to adopt it.

If the diameter of the socket wire is small, the current value that can be withstood is not enough, and the current of high-power electrical appliances is large, close to or exceeds the current carried by the socket wire, and the socket wire will heat up and become soft.

If the wire has resistance, when a large current passes through the wire, the wire will become soft at a certain temperature due to the heat generated by the resistance. In severe cases, it will melt, leak electricity, and cause fire. It is recommended to replace the wire with a larger wire diameter.

The wire is resistive, a certain thickness of the wire, can only withstand a certain current, the plug-in board also has its own current can withstand (such as 5A, 10A, etc. The thickness of the copper sheet is not the same), if the current of the large electrical appliances exceeds the rated value of the wire and the plug-in board, it will heat up, the plastic insulating skin will become soft, the current is large, the time is long, and even the insulating skin can be burned out, forming a short circuit, and even burning, leading to disaster.

If you don't understand this, I guess your explanation will be in vain!

Thermal relay is a protective appliance used for overload protection of motors or other electrical equipment and electrical circuits.

The working principle of the thermal relay: the current into the heating element generates heat, so that the bimetal sheet with different expansion coefficients is deformed, when the deformation reaches a certain distance, the connecting rod action is pushed to disconnect, so that the control circuit is disconnected, so that the contactor loses power, the main circuit is disconnected, and the overload protection of the motor is realized.

Function: Use: Mainly used for circuit overload protection, his working principle is that after the overload current passes through the thermal element, the bimetal sheet is heated and bent to push the action mechanism to drive the contact action, so that the circuit is disconnected to realize the load stop, and plays the role of overload protection.

Since it takes a long time for the heat to be transferred during the bending process of the bimetal sheet, the thermal relay cannot be used for short-circuit protection, but only for overload protection.

The protective appliances used for overload protection of motors or other electrical equipment and electrical circuits are called thermal relays.

1) The working principle of the thermal relay is to generate heat by the current flowing into the heating element, so that the bimetal sheet with different expansion coefficients is deformed, when the deformation reaches a certain distance, the connecting rod action is pushed to disconnect, so that the control circuit is disconnected, so that the contactor loses power, the main circuit is disconnected, and the overload protection of the motor is realized.

2) The thermal relay is composed of a heating element, a bimetal sheet, a contact and a set of transmission and adjustment mechanism. The heating element is a small resistance wire connected in series in the main circuit of the motor to be protected. Bimetal sheets are made by rolling two metal sheets with different coefficients of thermal expansion.

The lower layer of the bimetal sheet shown in the figure below has a large coefficient of thermal expansion and a small coefficient of thermal expansion for the upper layer. When the motor is overloaded, the current through the heating element exceeds the setting current, and the bimetal sheet is heated and bent upwards to break away from the gusset, so that the normally closed contact is disconnected. Because the normally closed contact is connected to the control circuit of the motor, its disconnection will make the contactor coil connected to it de-energized, so that the main contact of the contactor is disconnected, and the main circuit of the motor is de-energized, so as to achieve overload protection.

3) After the thermal relay is activated, the bimetal sheet is cooled down for a period of time, and the reset button can be reset.

4) Some models of thermal relays also have the function of phase failure protection. The phase-off protection function of the thermal relay is provided by a differential amplification mechanism composed of internal and external push rods. Reference.

What is a thermal relay and how it works, you will understand after reading the internal structure.

1.A relay that is driven by the heat generated by a sensitive element.

2.Only use it if the ** of the appliance is much more expensive than it.

3.It is equivalent to the function of a resettable fuse, and theoretically any electrical appliance can be used as long as the parameters match.

It is a kind of protection component that monitors the working current of the motor.

If there is no thermal relay in the power circuit of the motor, when the motor is out of phase, overload, winding short circuit and other faults, the control circuit can not cut off the motor power supply in time, which will further expand the fault and cause greater losses.

When the motor is in the normal working current, the component does not work, once the current exceeds the set value, the thermal resistance wire in the circuit will heat up, deform the bimetal sheet to push the execution switch, disconnect the control circuit, and protect the safety of the motor.

(l) When the electric hair dryer sends hot air, the motor and the resistance wire need to work at the same time, that is, the switch should be placed in position 1 in Figure A, and the electric fan and the heating wire are connected to the power supply in parallel, so they are connected in parallel

2) According to the image of the power change relationship with time, it can be seen:

P heat = 616W, T1 = 20s, P cool = 88W, T2 = 30S-20s = 10s, W total = W hot + W cold = P hot T1 + P cool T2 = 616W 20s + 88W 10s = 13200J

3) When blowing hot air, the motor and the resistance wire work at the same time, only the motor works when blowing the cold air, and the power of the heating wire is P=P hot-Pcool=616W-88W=528W, according to P=UI=U2R

The resistance of the heating wire is r=u2

p=(220v)2

After long-term use of 528W (4) incandescent bulbs, the tungsten filament becomes thinner due to sublimation, and the cross-sectional area becomes smaller, resulting in the resistance of the filament becoming larger; According to the formula p=ui=u2

r shows that the voltage at both ends of the bulb is constant, and the actual power of the bulb is inversely proportional to its resistance, and the actual power of the bulb decreases when the resistance increases

So the answer is: (l)1; Parallel connection; （2）13200；（3）；(4) Large; Small

In physics, it is said that the magnitude of the heat generated by an energized conductor is directly proportional to the value of the conductor's resistance. The resistance of the main body of the electrical appliance is very large, so the heat generation is very large, while the resistance of the wire is very small, so it rarely heats up.

That is, the main part of the power borne by the appliance itself. Otherwise, the wire is not called a wire, and it cannot be used to transmit electrical energy.

Because the working part of the appliance is much larger than the resistance of the wire. The heat generated by the current through the conductor is proportional to the quadratic of the current, proportional to the resistance of the conductor, and proportional to the time of energizing, i.e., Ohm's law p=i*i*r*t. Therefore, the heat of the working part and the wire are not hot.

It's called an electric heater, and there are many styles to choose from in the supermarket!

Heaters! However, it is a waste of electricity, and it is not as good as air conditioning.

Yes Electric heaters, plug in and it will heat up.

Fan heater. **Also sold online.

Hair dryer, multi-purpose.

The reason why the hot water flow of the electric water heater is small and the pressure relief valve is screaming:

The small flow of hot water in the electric water heater is due to the blockage of the hot water inlet end caused by the dirt inside the mixing valve, resulting in a small flow of water at the outlet;

The safety valve has a particularly loud sound, indicating internal overpressure;

The safety valve is clogged with scale, causing poor exhaust and making a sound.

Solutions to the above problems:

Remove the mixing valve and clean it to remove the scale and blockage caused by foreign matter inside. ensure that waterways are unobstructed; The steps are shown in the following figure:

The safety valve has a serious sound, indicating that the inside of the tank is overpressurized, and the cause of overpressure should be damage to the overtemperature protector and damage to the thermostat. As a result, the internal water is continuously heated and the expansion pressure increases, and the safety valve makes a serious noise in order to protect the internal pressure and discharge safely. At this time, professional repairers should be asked to repair in time to avoid the possibility of **;

The safety valve is blocked by scale due to poor water quality, resulting in unobstructed pipelines and screaming when the pressure is relieved. At this time, the safety valve should be removed for cleaning, or it can be replaced with a new one.

Precautions: When the electric water heater is repaired, be sure to cut off the power supply and unplug the internal water, and then disassemble it to avoid scalding.
