Abstract

The invention discloses a negative-pressure cooling power distribution control cabinet comprising a basic vertical cabinet body, a negative-pressure draught fan, exhaust pipelines and suction pipes. A plurality of element installation flat plates are arranged in the basic vertical cabinet body in parallel, so that the basic vertical cabinet body is divided into a plurality of containing cavities at intervals. The exhaust pipelines are arranged on the two sides of the inner portion of the basic vertical cabinet body. The top end of each exhaust pipeline is connected with a bottom air inlet of the negative pressure fan. The suction pipes are arranged in the containing cavities horizontally respectively. The two ends of each suction pipe are connected with the exhaust pipelines on the two sides respectively. A plurality of suction holes are evenly formed in each suction pipe. In this way, the negative-pressure cooling power distribution control cabinet prevents heat flow from reheating the electrical elements in other containing cavities, the cooling speed is high, and the working efficiency of the draught fan is high.
