Abstract
A centrifugal pump includes an electric motor. The electric motor has a motor casing and a base body. The electric motor comprises motor electronics which are carried by an arrangement for heat dissipation. The arrangement for heat dissipation has a contour, which corresponds to a contour of the motor casing, configured to at least partially directly contact of the two contours.
Claims20
A centrifugal pump comprising:
- an electric motor which has a motor casing and a base body, wherein
- the electric motor comprises motor electronics which are carried by an arrangement for heat dissipation, and
- the arrangement for heat dissipation has a contour, which corresponds to a contour of the motor casing,
- wherein
- the arrangement for heat dissipation has at least one recess configured for centering on a positioning element of a cooling rib of the motor casing,
- for centering the arrangement for heat dissipation on the motor casing, surface-area-Increasing elements of the arrangement for heat dissipation each have at least one recess corresponding to a positioning element, and
- heat-conducting elements of the motor casing have the same number of positioning elements as recesses formed on the surface-area-increasing elements.
