Abstract

A selective cooling electrical cabinet comprises a cabinet body (2), an installation plate (28), an electrical component (22) and a local cooling device. The installation plate (28) is fixed in the cabinet body (2) and used for installing the electrical component, the electrical component (22) is installed on the installation plate (28) and needs to be cooled, and the local cooling device is used for cooling the electrical component needing to be cooled. The local cooling device comprises a fixed bearing cylinder (9). The fixed bearing cylinder (9) is fixedly installed on the installation plate (28) and surrounds the electrical component needing to be cooled, and a ventilating opening (91) is formed in the bottom of the fixed bearing cylinder (9). An air path distribution ring part (8) with an annular cavity (80) is rotatably arranged on the outer circumferential wall of the fixed bearing cylinder (9) in a matched mode.

Description

technical field

[0001] This application relates to the field of electrical cabinets, in particular to an electrical cabinet that can be selectively cooled. 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 selectively cooled electrical cabinet which overcomes the disadvantages of the prior art.

[0004] The solution is an electrical cabinet with optional cooling, which includes a cabinet body, a mounting plate fixed in the cabinet body f...
