Description

technical field

[0001] The application relates to the field of electrical cabinets, in particular to an electrical cabinet capable of effectively cooling electrical devices. 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 an electrical cabinet capable of effectively cooling electrical devices, which can overcome the defects in the prior art.

[0004] The solution is an electrical cabinet capable of effectively cooling electrical componen...
