Device for controlling a pump with a heat sink

摘要

The device (20) has an electronic control board (30) housed in an outer casing (22), and heat sinks e.g. fin heat sink (40) and cover (42), carried by the casing and dissipating heat emitted by the board. A dielectric (34) electrically isolates the heat sinks from the board and assures heat conduction between the board and the heat sinks. An urging unit urges the heat sinks and the board one towards the other, and has an elastic tab (52) integrated to the casing and/or a seal arranged between the casing and the fin heat sink. The dielectric is compressed between the board and the heat sinks. An independent claim is also included for a fluid circulation pump comprising a motor.
