Abstract
A cooler for an electrical component, including a pressure-tight vessel enclosing the electrical component and including a support plate above the electrical component, a bath of electrically insulating and evaporating liquid surrounding the electrical component within the vessel, a flow channel for cooling liquid on the support plate, and a heat exchange element. The heat exchange element includes a serpentine plate having generally horizontally extending and aligned flanks alternately connected along horizontally extending upper and lower edges, with the lower edges being connected by connectors spaced along the horizontally extending edges and the upper edges being connected by horizontally extending crests secured to the flow channel for heat conduction therebetween. The flow channel may define a U-shaped path with two channel legs connected at one end, with a cooling liquid inlet connected to one of the channel legs and a cooling liquid outlet connected to the other of the channel legs. The connectors connecting the lower edges of the flanks are defined between cutouts extending minimally into the flanks, and no more than ¼ of the height of the flanks. The flanks define surfaces sloped no more than about 20° from vertical.
