Pump with an electronic housing and a heat sink

Abstract

The invention relates to a pump comprising a drive motor, at least one electronics housing, and at least one heat-conducting heat sink for discharging heat from the electronics housing, wherein an intermediate piece is introduced between the heat sink and the motor housing to thermally decouple the heat sink from the motor housing, and the intermediate piece has at least one through-opening for passing through at least one component between the motor housing and the heat sink. The invention is characterized in that the intermediate piece is made of an elastic material, and the intermediate piece is compressed in the region about the at least one through-opening as a result of the geometry thereof in order to seal the region of the through-opening from the surroundings.
