Abstract

An electrical cabinet capable of partially cooling is disclosed. The electrical cabinet comprises a cabinet body (2), a mounting plate (28) fixed in the cabinet body (2) used for mounting electrical devices, the electrical devices (22) mounted on the mounting plate (28) and required to be cooled, and a partial cooling apparatus for cooling the electrical devices required to be cooled; the partial cooling apparatus comprises a fixed bearing barrel (9) fixedly mounted on the mounting plate (28) around the electrical devices required to be cooled, and a ventilation opening (91) is formed in the bottom of the fixed bearing barrel; and a gas path distribution annular part (8) with an annular cavity (80) is rotationally matched on the outer circumferential wall of the fixed bearing barrel (9).

Description

technical field [0001] The application relates to the field of electrical cabinets, in particular to a locally cooled power electrical cabinet. Background technique [0002] Electrical cabinets typically house various electrical components. In these electrical components, the heat generation and heat dissipation are the same. For the entire electrical cabinet, its safety and stability often depend on the position or point where heat generation is the highest. However, conventional heat dissipation methods are difficult to dissipate or cool down the heat accumulation area or single / multiple heat in the electrical cabinet in a targeted manner. Contents of the invention [0003] The object of the present invention is to provide a locally cooled electrical cabinet, which can overcome the defects in the prior art. [0004] The solution is a local cooling electric power cabinet, including a cabinet body, a mounting board fixed in the cabinet body for installing electrical dev...
