Power cabinet with good heat dissipation performance

Abstract

The invention discloses a power cabinet with good heat dissipation performance. The power cabinet comprises a cabinet body and a cabinet door; the cabinet door and the cabinet body enclose to form anaccommodating cavity for accommodating components, a partition plate is arranged in the cabinet body and divides the accommodating cavity into a heat dissipation cavity located at the lower part and acomponent cavity located at the upper part, and a plurality of communication holes are formed in the partition plate; the communication holes enable the heat dissipation cavity to be communicated with the component cavity; a fan set is arranged in the heat dissipation cavity, air inlets are formed in the left side and the right side of the heat dissipation cavity, a flow guide plate is arranged in the middle of the heat dissipation cavity, and the flow guide plate is used for guiding cold air vertically flowing into the heat dissipation cavity from the left air inlet and the right air inlet into vertically-upward cold air. Cold air flows into the component cavity orderly and smoothly through the plurality of communication holes, takes away heat in the component cavity and then flows out from the air outlet in the right side of the component cavity, and the heat dissipation effect of the heat dissipation device is very good due to smooth and orderly flowing of the cold air.

Description

technical field [0001] The invention relates to the field of electric power, in particular to an electric cabinet with good heat dissipation performance. Background technique [0002] The power cabinet, also known as the control cabinet, is a closed or semi-closed metal cabinet that assembles components such as switchgear, measuring instruments, protective appliances and auxiliary equipment in accordance with the requirements of electrical wiring. The inside of the cabinet is loaded with continuously working components and has a large current. Therefore, the heat generated inside the power cabinet is relatively large. It is necessary to increase the cooling fan to actively dissipate heat inside the power cabinet. In order to avoid dust falling, the cooling holes are generally opened in the power cabinet. The side of the power cabinet is not the top, so that the cold air entering the power cabinet vertically will scurry inside the power cabinet, and the flow will not be smoot...

It is necessary to increase the cooling fan to actively dissipate heat inside the power cabinet. In order to avoid dust falling, the cooling holes are generally opened in the power cabinet. The side of the power cabinet instead of the top, so that the cold air entering the power cabinet vertically will scurry inside the power cabinet, and the flow will not be smooth, resulting in poor heat dissipation
