What Components Make Up a Car Heating System?

[LeFelix]

An automotive heating system consists of the following components: 1. Refrigeration system. 2. Heating system. 3. Ventilation and air purification devices with control systems. 4. Evaporator, heater radiator, centrifugal blower, and control mechanism. Below is the working principle of a car heating system: 1. When the engine is running, high-temperature combustion in the engine cylinders heats the coolant. Under the action of the engine cooling system's water pump, the coolant enters the heat exchanger through the inlet pipe. The blower then blows air to transfer the heat dissipated by the coolant into the passenger compartment or onto the windshield, thereby raising the interior temperature and defrosting. 2. During the heat dissipation process in the heat exchanger, the coolant is drawn back by the water pump through the return pipe, creating a continuous cycle to provide warm air heating.
