What will happen if Wuling light turns on the warm air and the water temperature drops?

The structure of the heater is actually the same as the water tank of the car, and the working principle is the same.

When the air heater is turned on, the hot water in the water channel on the engine cylinder head enters the upper part of the water tank of the air heater, and the cooling fan operates to discharge heat into the trunk. The water in the water tank is cooled to the bottom of the water tank, and enters the waterway at the bottom of the machine body from the water pipe at the bottom of the water tank to continue circulation.

Because the temperature of water in the engine, water tank and warm air radiator is high in the upper part and low in the lower part. The heater needs hot water, so the water inlet pipe of the radiator of the heater is installed on it, not the water tank inlet pipe at the bottom of the water tank.

Because the heater, like the water tank, is also the second radiator of the engine, the water temperature will drop when the heater is turned on.
