Panel-type radiator for electrical apparatus

摘要

This panel-type radiator for extracting heat from liquid flowing therethrough comprises a panel through which the liquid flows in a downward direction. The panel is made from two dished metal sheets having aligned vertically-extending embossments welded together along a vertically-extending zone and providing spaced vertically-extending flow channels on opposite sides of the vertically extending zone. The portions of the sheets defining the walls of said channels are provided with vertically-spaced embossments arranged on each sheet in a generally herringbone pattern, with the individual embossments extending transversely of the vertically-extending zone via a path that slopes upwardly as the vertically-extending zone is approached.
