A parking heater is a heating device that is independent of the car's engine, and its main function is to provide heat to the driver's cabin, the cargo area, and the engine system when the vehicle is turned off, thereby solving problems such as the difficulty of starting the vehicle and the inconvenience of heating the interior in low-temperature environments.
Its working principle is to generate heat through the combustion of fuel (such as diesel or gasoline), transfer the heat to the air or cooling liquid via a heat exchanger, and then deliver it to the target area through a fan or circulation system. Based on the heating object, it can be divided into air heaters (directly heating the air inside the vehicle) and liquid heaters (heating the engine coolant to simultaneously provide heating for the vehicle interior and preheat the engine).
The parking heater is suitable for trucks, buses, motorhomes, and other vehicles in cold regions during winter, which can preheat the engine, reduce wear during cold starts, and quickly raise the interior temperature, thereby improving the comfort of both driving and riding, and serving as an important auxiliary device for ensuring the reliable operation of vehicles in low-temperature environments.
