Efficient heat dissipation electric appliance box with sealing performance

Abstract

The invention relates to an efficient heat dissipation electric appliance box with sealing performance. The electric appliance box comprises an electric appliance box body, the electric appliance boxbody is provided with an opening, a box cover is hinged to one side surface of the opening; and EVA foam is arranged on the edge of the opening. A through hole is formed in the side surface, away fromthe opening, of the electrical box body; and extending pieces are arranged at the upper end and the lower end of the through hole of the electric appliance box body in an outward-extending mode. A U-shaped heat dissipation plate is arranged in the through hole; and the upper end and the lower end of the U-shaped heat dissipation plate are in sealed connection with the adjacent extending pieces through sealants. A plurality of radiating fins are uniformly distributed on the side surface, far away from the opening, of the U-shaped heat dissipation plate; a graphene heat conduction film is arranged on the side face, close to the opening, of the U-shaped heat dissipation plate, a heating device is arranged in the electric appliance box body and fixed to the U-shaped heat dissipation plate, corrugated plates are arranged on the two sides of the electric appliance box body, a ventilation valve is arranged on the inner bottom face of the electric appliance box body, an installation hole is formed in the upper face in the electric appliance box body, and a drying mechanism is arranged in the installation hole. The efficient heat dissipation electric appliance box has the advantages of lowcost, convenient installation, and efficient and stable heat dissipation.

Description

technical field [0001] The invention relates to the technical field of heat dissipation for electrical boxes, in particular to an electrical box with airtightness and high efficiency for heat dissipation. Background technique [0002] There are precision circuit boards and electrical components installed inside the electrical box. When these electrical components are used, they will generate a lot of heat due to the thermal effect of the current. This heat will cause damage to the electrical components and reduce the service life. structure, improving safety and service life. However, the current heat dissipation structure of the electrical box usually adopts a water tank heat dissipation structure, and the water tank heat dissipation structure has problems such as regular replacement of coolant / water, complicated installation and high cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to solve the above problems and pr...
