Electric refrigerant compressor

Abstract

To provide an electrical refrigerant compressor in which improved cooling and an improvement in the EMC properties of heat-producing electronic components, in particular DC link capacitors and electronic power switches, of an inverter can be achieved.SOLUTION: An electrical refrigerant compressor includes a drive unit, a compressor unit, and a motor housing (2.1). The compressor unit forms a shaft (6.1) and a fluid-tight inverter housing (4.1). An inverter circuit board (7.1) has heat-producing electronic components, in particular, at least one DC link capacitor (9.1) and a plurality of electronic power switches (11.1), and has at least two different component heights (18; 19) perpendicular to the inverter circuit board (7.1), is accommodated in a plurality of moldings (16; 17) which are formed according to the component heights (18; 19), on a refrigerant-exposed housing wall (12), and is thermally coupled to the moldings.SELECTED DRAWING: Figure 3b
