Abstract
Described herein are DC-DC converters with electronic module cooling units used for air-convection cooling of some components of power electronic modules and conductive cooling of other components, e.g., switching sub-modules. A cooling unit may have a heat exchanger and a cooling plate, thermally coupled to one or more heat exchangers and one or more switching sub-modules. For example, the cooling plate can be positioned between and thermally coupled to heat exchangers. One fan can direct air through one heat exchanger and to one power electronic module as a part of convection cooling. An additional fan can direct air through the second heat exchanger and to the second power electronic module. The cooling plate can be also positioned between and thermally coupled to switching sub-modules of these power electronic modules thereby enabling conductive cooling. The plate-cooling liquid is pumped through the cooling plate.
