Heat dissipation device of electrical control device

Abstract

The invention belongs to the technical field of heat dissipation of electrical devices, and discloses a heat dissipation device of an electrical control device. The heat dissipation device comprisesa cabinet body and a fan assembly mounted at the top of the cabinet body, an upper cavity and a lower cavity are sequentially formed in the cabinet body from top to bottom, the upper cavity and the lower cavity are correspondingly provided with independent cabinet doors, and heat dissipation holes are symmetrically formed in two sides of the lower cavity; and an air filtering assembly is installedin the lower cavity and comprises a fixed porous bottom plate, a lifting type filter screen and a rotary type swing assembly which are sequentially arranged from top to bottom. According to the invention, the movable filter screen and the fixed porous bottom plate are arranged in a matched manner, so that when the filter screen is limited at the highest horizontal position, the filter screen is communicated with the porous plate, and rapid heat dissipation operation of upward circulation of airflow is further realized; when the filter screen is limited at the lowest horizontal position, the porous bottom plate is closed, and meanwhile, the downward heat dissipation of airflow and the backwashing operation of the filter screen are realized in cooperation with the heat dissipation clampingcavity; and, in conclusion, the filter screen can be reversely cleaned under the condition that the filter screen is not disassembled.

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 ...
