1. Using the heat of cooling water, blow it into the cab from the window with a fan. Generally speaking, turning on the engine during driving will not improve the heat dissipation of the car, because the heat in the cooling water is continuously obtained from the engine body (to keep the engine temperature from being too high), but turning on the engine just after starting in winter will make the engine fail to work normally (80 degrees Celsius) for a long time.
2. Cars are different from air conditioners. The water temperature is used for heating, which is the water tank. When the temperature rises to 85℃, there is a thermostat to open the ventilation pipe. Shui Rou pipe comes to the car's interior, passes through the aluminum radiator in the cab, and then a blower blows out hot air, which becomes heating. There was no heating when the car first started.
3. The simple heat flow is as follows: the residual heat in the cylinder → the coolant is heated → the water pump drives the coolant to flow → the thermostat (a temperature valve) → the heater in the air conditioner is heated →-the coolant flows back to the water channel in the cylinder. Through this cycle, the heat generated by the engine is used to provide us with warmth. The working principle of the bus heater is that the circulating cooling water of the engine is used as the heat source, and the water temperature booster (patented product) is used as the heat source of the heater and defroster to reheat the circulating water (the water temperature can reach more than 90 degrees), and then heat exchange is carried out through the efficient radiator, and hot air is blown out by the fan for heating and defrosting.
