Description
Technical Field

Background
With the pressure of environmental protection and energy, new energy automobiles develop rapidly, and vehicle-mounted air compressors are widely applied. In recent years, new energy vehicles are more compact and lightweight, and therefore many parts of the new energy vehicles need to be miniaturized and have compact layouts. For important actuating mechanisms such as a vehicle-mounted air compressor and the like which need heat dissipation, the heat dissipation space is smaller and smaller, the heat dissipation environment is more and more harsh (the environment temperature is high, other mechanisms dissipate heat, the effective heat dissipation space is small, dust covers and the like), and under the harsh condition, the vehicle-mounted air compressor is easy to generate high-temperature alarm to stop the operation of the whole vehicle.
The most important external reasons for the vehicle-mounted air compressor to generate high-temperature alarm and stop running are the following, in addition to the quality or design problems of the vehicle-mounted air compressor: the ambient temperature is high, resulting in an excessively high suction temperature. If the temperature of the environment where the vehicle-mounted air compressor is located can be effectively controlled, high-temperature alarm caused by high suction temperature can be fundamentally solved. The new energy automobile has the strategy of controlling the environment where the vehicle-mounted air compressor is located by using the whole air conditioning system for refrigeration or heating. Although the control strategy can control the temperature of air sucked by the air compressor, the problem of high-temperature alarm of the whole machine is solved. However, the environment in which the on-board air compressor is required to be located is "insulated" from other mechanisms, and establishing such an insulated environment requires significant investment in technology and manufacturing costs. Even if the heat insulation condition can be created, the vehicle-mounted air compressor can consume a large amount of energy of the whole vehicle air conditioning system to control the ambient temperature in the working process. (the new energy automobile can output a large amount of electric energy, and the ambient temperature of the vehicle-mounted air compressor is controlled through the air-conditioning system)
