A heat dissipation device, a speed regulating module and an automobile air conditioner

Abstract

The invention discloses a heat dissipation device for a speed regulation module of an automobile air conditioner, a speed regulation module and an automobile air conditioner, and belongs to the technical field of automobiles. , a plurality of heat pipes are arranged at intervals on the heat conduction base, and a plurality of heat dissipation fins are provided, and a plurality of heat dissipation fins are arranged at intervals along the extension direction of the heat pipe at the end of the heat pipe away from the heat conduction base, and each heat pipe is installed on a plurality of heat dissipation fins. The heat generated by the field effect tube is transferred to the heat pipe through the heat conduction base and dissipated outward through the heat dissipation fins, so as to realize the rapid heat dissipation of the field effect tube. Compared with the prior art, it has a higher heat exchange efficiency; , The gap between the heat dissipation fins is relatively large, and the resistance to the airflow blown by the blower is small, so that the airflow blowing to the evaporator is more uniform, avoiding large-scale eddy currents around the speed control module, and improving the temperature uniformity of the evaporator air outlet .

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a heat dissipation device for a speed control module of an automobile air conditioner, a speed control module and an automobile air conditioner. Background technique [0002] Car air conditioner is a device that realizes cooling, heating, ventilation and air purification of the air in the car, which can provide passengers with a comfortable riding environment and improve driving safety. Therefore, car air conditioners have become an indispensable and important accessory for cars. [0003] The speed regulation module of the car air conditioner blower is used to control the speed and air volume of the car air conditioner blower, provide different wind speeds required by passengers, and improve the comfort of the whole vehicle. The main working principle of the speed control module is: after the control panel of the air conditioner sends a signal to the speed control module, the...
