Summer when we drive will be used to turn on the car air conditioning, the air conditioning in the car can make us not surrounded by hot air, can better drive the car, but the friends we use the car air conditioning in the summer we have not to go to the maintenance.
The heat source of the hot water heating system usually uses the cooling water of the engine, so that the cooling water flows through a heater core, and then the air blower blows the cold air through the heater core to heat the air, so that the temperature of the car rises
Hot water heating system is mainly composed of heater core, water valve, blower, control panel, etc.
(1) heater core
Composed of a water pipe and a radiator piece, the cooling water of the engine enters the water pipe of the heater core, dissipates heat through the radiator piece, and then returns to the cooling system of the engine.
Water valve
The water valve is used to control the amount of water entering the heater core, and then adjust the heat of the warm air system. When adjusting, it can be controlled by the adjusting rod or knob on the control panel
blower
The blower is composed of a DC motor with adjustable speed and a squirrel cage fan. Its function is to blow the air through the heater core and then heat it into the car. Adjust the speed of the motor, you can adjust the amount of air sent to the car.
As far as the warm air system is concerned, there are two kinds of temperature regulation, one is air mixture type, the other is water flow regulation type.
Air mixture
This type of warm air system is equipped with air mixing damper in the warm air airway. This damper can control the proportion of air passing through the heater core and air not passing through the heater core to achieve temperature regulation. Currently, most cars use this method.
