A cooling device for an electrical control device

Abstract

The invention belongs to the technical field of heat dissipation of electric devices, and discloses a heat dissipation device of an electric control device, which includes a cabinet body and a fan assembly installed on the top of the cabinet body. An upper chamber and a lower chamber are sequentially formed in the cabinet body from top to bottom. In addition, the upper chamber and the lower chamber are respectively equipped with independent cabinet doors, and the two sides of the lower chamber are symmetrically provided with heat dissipation holes; the air filter assembly is installed in the lower chamber, and the air filter assembly includes fixed ones arranged in sequence from top to bottom. Porous bottom plate, lifting filter screen and rotary swing assembly; in the present invention, a movable filter screen and a fixed porous bottom plate are arranged together: when the filter screen is limited to the highest level, the conduction between the filter screen and the porous plate is realized, In order to realize the rapid heat dissipation operation of the upward flow of air flow; when the filter screen is limited to the lowest level, the porous bottom plate is closed, and at the same time cooperate with the cooling chamber to realize the heat dissipation of the air flow downward and the backwashing operation of the filter screen; in summary, the filter screen is not disassembled The reverse cleaning of the filter can be realized by pressing down.

Description

technical field [0001] The invention belongs to the technical field of heat dissipation of electric devices, and in particular relates to a heat dissipation device of an electric control device. Background technique [0002] Electrical control devices mainly refer to electrical control cabinets, which are used to install various electrical components as terminal equipment for controlling the use of electrical energy. In actual use, due to the heat generation and heat dissipation generated by the electrical components during operation, the temperature in the overall electrical control device will gradually increase, which in turn will affect the service life of the electrical components. high. [0003] Based on the above problems, the prior art mainly includes heat dissipation methods such as wind circulation and water circulation. Taking wind circulation as an example, the principle is to increase the air circulation speed in the electrical control device to accelerate the ...
