Electrical device with heat dissipation structure

Abstract

The invention discloses an electrical device with a heat dissipation structure, which comprises a cabinet body, the cabinet body is provided with a cabinet door, a turbofan is clamped on the inner wall of the cabinet body through a through hole, filter nets are provided on both sides of the turbofan, the cabinet body There are cold air chambers on both sides of the body, and a cooling fan is installed in the cold air chamber. The top of the cabinet is equipped with an air outlet pipe, a filter box, an exhaust pipe and an air negative pressure machine. The filter box is divided into a porous foam layer, a filter layer and a support layer. In order to solve the shortcomings of the switch cabinets in the prior art, the present invention proposes an electrical device with a heat dissipation structure. The cabinet body and cabinet door are sealed, and the turbofan automatically generates strong power through the dual effects of negative pressure and temperature difference. Cool air, and form a cold air vortex, to carry out powerful blowing heat dissipation on the cabinet body, high heat dissipation efficiency, wide range of cold air diffusion, no heat exchange dead zone, so as to meet the heat dissipation requirements of modern electronic equipment, and at the same time have the effect of dustproof and moisture-proof .

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to an electrical device with a heat dissipation structure. Background technique [0002] Switchgear refers to a complete set of power distribution devices assembled by primary equipment and secondary equipment according to a certain plan, and is mainly used to control and protect lines and equipment. The switchgear can be divided into high-voltage switchgear (fixed type and handcart type) and low-voltage switchgear (fixed type and drawer type) according to the voltage level of the incoming and outgoing lines. The structure of high-voltage switchgear is generally similar, mainly divided into busbar room, circuit breaker room, secondary control room (instrument room), feeder room, and steel plates are generally used to isolate each room. Low-voltage switchgear is mainly classified according to the installation method of components. [0003] In the hot summer, residential ele...
