A cooling box and a switchgear

Abstract

The invention belongs to the technical field of electrical heat dissipation equipment, and discloses a heat dissipation box, which includes a shell, a primary heat dissipation component and a secondary heat dissipation component; the primary heat dissipation component includes a primary heat dissipation plate, and the primary heat dissipation plate is provided with a primary heat dissipation hole , the first-level heat dissipation holes output the heat inside the shell to the outside; the second-level heat dissipation assembly includes a second-level fixed plate, a second-level moving plate and a deformable part, the second-level moving plate and the deformable part are located on the inner side of the second-level fixed plate, and the deformable part One end is connected to the inner wall of the shell, and the other end of the deformed part is connected to the secondary moving plate. The secondary moving plate is provided with a connection hole, and the secondary fixed plate is provided with a secondary cooling hole. The secondary moving plate is driven to move on one side of the secondary fixing plate, and the connecting hole of the secondary moving plate can be connected to the secondary cooling hole of the secondary fixing plate to connect the outside world and the inside of the shell. The switchgear of the present application adopts the above-mentioned heat dissipation box, and realizes multiple heat dissipation and dustproof functions through multi-stage heat dissipation components.

Description

technical field [0001] The invention belongs to the technical field of electric cooling equipment, and in particular relates to a cooling box and a switch cabinet. Background technique [0002] The switchgear is a kind of electrical equipment. There are many electrical components inside the switchgear. These electrical components will release a lot of heat during the working process. If the heat cannot be discharged from the switchgear, the internal temperature of the switchgear will rise. , causing electrical components to overheat and break down, and the general heat dissipation method is to set louvers in the switch cabinet and add a cooling fan to discharge the heat in the switch cabinet. The concept is contrary to the concept. At the same time, the cooling fan will send the dust to the inside of the switch cabinet while blowing air, which will cause great harm to the electrical components. Contents of the invention [0003] The purpose of the present invention is to ...
