The invention relates to a centrifugal pump (2) having an electric motor (1) with a motor housing (3) and a base body (7). The electric motor (1) comprises motor electronics (4). The motor electronics (4) are carried by an arrangement (5) for dissipating heat. According to the invention, the arrangement (5) for dissipating heat has a contour (9) which is designed in accordance with a contour (10) of the motor housing (3) for direct contact of the two contours (9, 10). 本发明涉及一种离心泵(2)，其具有电动马达(1)，该电动马达具有马达壳体(3)和基体(7)。电动马达(1)包括马达电子器件(4)。马达电子器件(4)由用于导出热量的布置结构(5)来承载。用于导出热量的布置结构(5)具有轮廓(9)，该轮廓与马达壳体(3)的轮廓(10)相应地构造，以用于两个轮廓(9、10)的直接接触。
