Box-type cooler - for power semiconductor modules insulated by layer of specified plastic material

摘要

The heat loss of power semiconductors is carried away by box-type cooling units (1), made of conductive material (Cu, Al) with a fluid inlet (2) and outlet (3) and several cooling channels (5) separated by webs (4). The cooling box is electrically insulated by a 1-3 mm thick layer (6) made of unsaturated polyester and/or epoxy resin and/or modified polyestyrene such as STYCAST (RTM). The outer part (7) is made of copper. ADVANTAGE - This insulating material combines an effective electrical separation with a good heat conductivity and ensures that the unit has a high cooling capacity.
