Principle of heater water tank: In addition to a radiator in the engine compartment, there is also a heat exchanger in the dashboard of the cab. What flows in the middle is the antifreeze used for cooling in the engine. Turning on the heater can improve the car's heat dissipation, which is especially useful for some Jettas when running long distances. It uses the cooling water of the engine as the working medium. Under the action of the blower, it is blown from the same air outlet into the vehicle room to achieve the purposes of heating, ventilation and defrosting. In terms of air intake mode, it mainly has two states: one is for indoor air circulation, and the other is for outdoor fresh air to enter the vehicle interior for ventilation circulation. The blower is driven by electricity and is not affected by the engine speed. Even when the engine speed is very low, it can still perform heating and defrosting functions.
