Abstract

The invention provides an electrical cabinet, and belongs to the technical field of power equipment. The electrical cabinet comprises a shell, a heat dissipation assembly and a piston pump, wherein an air inlet and an air outlet are formed in the outer wall of the shell, a cooling cavity, a first containing cavity and a second containing cavity which are isolated from one another are formed in the shell, the first containing cavity is communicated with the air outlet, the heat dissipation assembly comprises a heat dissipation pipe, the input end of the heat dissipation pipe is located in the first containing cavity, the output end of the heat dissipation pipe is located in the second containing cavity, the part between the input end and the output end of the heat dissipation pipe is located in the cooling cavity, the piston pump is located in the second containing cavity, a first sealing cavity and a second sealing cavity which are variable in volume are formed in the piston pump, and the volume change of the first sealing cavity and the volume change of the second sealing cavity are in negative correlation. According to the invention, the heat dissipation effect of the electrical element can be improved.

Description

technical field [0001] The disclosure belongs to the technical field of electric equipment, and in particular relates to an electric cabinet. Background technique [0002] The electrical cabinet is made of steel and is used to protect the normal operation of electrical components. It is widely used in all walks of life. When the electrical components inside the electrical cabinet are running, they will emit heat, which will increase the internal temperature of the electrical cabinet. Therefore, it is necessary to dissipate heat in the electrical cabinet in time to avoid affecting the normal operation of the electrical components. [0003] In the related art, when the electrical cabinet is performing heat dissipation, a cooling fan is generally installed inside, and the inside of the electrical cabinet is blown through the cooling fan, and then the heat inside the electrical cabinet is conducted out through the cooling teeth or cooling holes of the electrical cabinet, thereby...
