HEATSINK FOR POWER ELECTRONICS COOLING

A refrigeration unit including a compressor (32) includes a refrigeration circuit, a mounting plate (54), a power electronics device thermally coupled to a surface (52) of the mounting plate (54), and a heat sink (60) thermally coupled to the mounting plate (54) and to a component (suction tube 64) of the refrigeration circuit. The heat sink (60) is configured to transfer waste heat from the mounting plate (54) to the component of the refrigeration circuit. Use in a transport refrigeration unit.
