Abstract

The present invention relates to a pump motor with an isolation tank. The pump motor has a motor housing (10), a pump head (11), and an isolation tank(3), wherein the pump head and the isolation tank delimit the wet chamber (26); and the isolate the tank and the motor housing (10) delimit a dry chamber (25); the permanent magnet rotor (2) being supported in the wet chamber (26) so as to be rotatable about an axis (49), the winding type stator and a circuit board (20) are arranged in the dry chamber (25), and the circuit board (20) is opposite the isolation tank bottom (17). It is an object of the present invention to provide a reliable thermal output with increased heat removal power from a circuit board (20) to a medium to be conveyed in such a pump motor in an economical manner. This task is solved by the fact that the isolation tank bottom (17) has a recess (18) on the side opposite the circuit board (20) and a projection (19) on the opposite side.

Description

technical field [0001] The invention relates to a pump motor (1) with a motor housing (10), a pump head (11) and an isolating tank (3), wherein the pump head (11) and the isolating tank (3) delimit a wet chamber ( 26) and the dry chamber (25) is bounded by the isolation tank (3) and the motor casing (10), the permanent magnet rotor (2) is supported in the wet chamber (26) in a manner that can rotate around the axis (49), around The wire-type stator (4) and circuit board (20) are arranged in the dry room (25) and the circuit board (20) is opposite to the isolation tank bottom (17). Background technique [0002] In internal combustion engines in the automotive sector, there is usually a mechanical pump driven by the crankshaft via a toothed belt as the main coolant pump. As an aid or as an alternative to a stalled internal combustion engine, an electric supplementary cooling pump is used, usually in the form of an electronically commutated DC motor. The main coolant pump can...
