Cooling device for speed control module of automobile air conditioner

Abstract

The embodiment of the invention discloses a heat radiating device for a speed-regulating module of an automotive air conditioner and relates to the technical field of automobiles. The radiating device is invented for solving the technical problem of poor heat radiating effect of the speed-regulating module in the prior art. The speed-regulating module of an automotive air conditioner fan comprises a radiator, wherein a heat radiating fin is arranged at the bottom of the radiator and a base is connected with the top of the radiator, wherein a first side wall and a second side wall which are opposite to each other are arranged on a plane at the top of the radiator; a first insert plate is formed on the first side wall in a extending manner; a second insert plate is formed on the second side wall in an extending manner; a first slot matched with the first insert plate and a second slot matched with the second insert plate are arranged on the base; and after the first insert plate is matched with the first slot and the second insert plate is matched with the second slot, a heat radiating space for accommodating a circuit board and a field-effect tube in mutual connection is formed between the radiator and the base. The heat radiating device provided by the invention is used for realizing the radiation for the speed-regulating module.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a heat dissipation device for an automobile air conditioner speed regulating module. Background technique [0002] Automobile air conditioner is a device that cools, heats, ventilates and purifies the air in the compartment. It can provide passengers with a comfortable riding environment, reduce driver fatigue, and improve driving safety. Therefore, automotive air conditioners have become An important accessory that is indispensable to the car. [0003] The speed regulation module of the automobile air-conditioning blower is used to control the speed and air volume of the automobile air-conditioning blower, provide different wind speeds required by passengers, and improve the comfort of the 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 field effect transistor ...
