1. Repair the cooling fan. The cooling fan of the air conditioner is faulty, resulting in poor heat dissipation. You need to repair the cooling fan.
2. Clean the water tank. Check whether the tank is blocked. If the tank is blocked, clean the tank.
3. Replace the air conditioner filter element. Air conditioning filter dirty will affect the air intake of air conditioning, the driver should replace the new air conditioning filter in time.
4. Add coolant. If the coolant is insufficient, the cooling circulation flow is reduced, the air conditioning temperature will rise, and the coolant needs to be added in time.
5. Clean the condenser. The air conditioner condenser is in front of the radiator, if the condenser is dirty, the air flow is difficult to reach the radiator, resulting in bad heat dissipation of the air conditioner, and the condenser needs to be cleaned.
6. Clean the radiator. The blocked radiator of the air conditioner also causes poor heat dissipation of the air conditioner. You need to clean or repair the radiator of the air conditioner.
7. Dredge the return water pipe. Check whether the return water pipe at the top of the coolant storage tank is not smooth. If the return water pipe is blocked, dredge the return water pipe in time.
8. Repair the thermostat or water pump. If the temperature difference between the upper and lower pipes of the water tank is large, it is necessary to check whether the opening of the thermostat is normal, whether the speed of the water pump is faulty, and the thermostat or water pump is faulty.
9. Replace the coolant. If the coolant is not replaced for a long time, it will lead to blockage of the engine water channel and water tank, and it is necessary to clean the engine water channel and water tank, and replace the new coolant.
10. Discharge the refrigerant oil from the air conditioner. If the refrigerant oil of the air conditioner is too much, the condenser pressure will be too high, and the heat dissipation of the air conditioner is not good. You need to remove the air conditioner compressor, unscrew the oil screw, and pour out the excess refrigerant oil.
Poor heat dissipation of the air conditioning system will lead to weak acceleration of the car, increased engine noise, and poor air-conditioning refrigeration effect, and it is necessary to go to the 4s shop to repair the vehicle in time.
1. There are ways to improve the problem of poor heat dissipation of car air conditioning.
2. The reason for the poor heat dissipation of the automobile air conditioner may be that the condenser or radiator in the air conditioning system is blocked or damaged, resulting in the effective heat dissipation.
This problem can be solved by cleaning the condenser and radiator to ensure that their surface does not accumulate too much dust and debris; Check whether the cooling fan is working normally. If not, repair or replace it. Ensure that the cooling system of the vehicle has sufficient coolant and does not overheat.
3. In addition, you can also consider reducing the exposure time of the vehicle to the sun in high temperature weather, avoid exposing the vehicle to high temperature environment when parking, you can choose to use the sunshade when parking or park the vehicle in the shade.

In addition, regular maintenance of the car air conditioning system, including replacing the air conditioning filter and checking the refrigerant charging and discharging, can also effectively improve the problem of poor heat dissipation of the car air conditioning.
Is the heat sink too dirty, clean the heat sink on the line
