Cooling device for cooling internal combustion engine of motor car, has coolant pump arranged in high temperature-cooling circuit, and including cooling unit cooling electronics and fastened at low temperature-cooling circuit

摘要

The device has a coolant pump (12) e.g. electrical pump, arranged in a high temperature-cooling circuit (10), and including a cooling unit (14) i.e. sheet plate, for cooling an electronics (13). The cooling unit is fastened at a low temperature-cooling circuit (11). The pump includes a pump housing (15), in which the low temperature-cooling circuit is introduced separately from the high temperature-cooling circuit. An additional coolant pump (16) is arranged in the low temperature-cooling circuit. A heat transport medium (18) i.e. cooling water, flows through the circuits to cool components.
