Rectifier air cooling system with two-chamber housing - has heat sinks for electric components brought out through insulating partition to chamber with fresh air flow

摘要

The cooling system consists of a housing which has a dust-proof chamber for electric components with closed air circulation. A second chamber (4) is supplied with fresh air, and the heat generated by the electric components is conducted to this chamber by a heat tube passing through the wall separating the two chambers. If several heat tubes are used, their condensation sides are arranged one behind the other in the air flow direction in the second chamber. The electric components (14, 15) have additional heat sinks (10), protruding into the second chamber (4) through an insulating plate (1) forming the partition between the two chambers. The heat sinks are mounted in the second chamber one behind the other in the air flow direction. The heat tubes are located in the inlet section of the fresh air flow.
