Title:
ELECTRIC COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2023/190366
Kind Code:
A1
Abstract:
A switching element (70) has: a conductive member (71); and a rectangular cuboid-shaped resin member (72). The resin member (72) has: a first end surface (72a) which is an end surface in a longitudinal direction thereof and through which a portion of the conductive member (71) protrudes; a second end surface (72b) that is located on the opposite side from the first end surface (72a); and a first lateral surface (72c) that links the first end surface (72a) and the second end surface (72b). The conductive member (71) has a heat generation part (73a) that is exposed at the first lateral surface (72c). The switching element (70) is disposed in an inverter housing chamber (S1) such that the longitudinal direction of the resin member (72) extends in the axial direction of a rotation shaft. A heat dissipation member (80) made of a metal is disposed between the switching element (70) and a partitioning wall (22). The heat dissipation member (80) has: a first heat dissipation part (81) that is disposed between a heat generation part (73a) and the partitioning wall (22); and a second heat dissipation part (82) that is continuous to the first heat dissipation part (81) and is disposed between the second end surface (72b) and the partitioning wall (22).
