Abstract
The invention relates to a cooling module for a vehicle control unit, comprising a cooling element, connections for conducting a coolant through the cooling element, a turbulence insert placed in the cooling element comprising at least first cooling fins, and at least one first bimetal located in the cooling element, wherein the at least one first bimetal is placed such that it displaces the at least one group of first cooling fins depending on a temperature-dependent shape change of the at least one first bimetal. The invention also relates to a vehicle control unit with a cooling module and a method for water cooling a vehicle control unit.
Claims12
A cooling module for a vehicle control unit, comprising:
- a cooling element;
- connections, for conducting a coolant through the cooling element;
- a turbulence insert comprising at least a first set of cooling fins located on the cooling element;
- and
- at least one bimetal located in the cooling element,
- wherein the at least one first bimetal is placed such that it displaces the first set of cooling fins depending on a temperature-dependent change in shape of the at least one first bimetal.
A method for water cooling a vehicle control unit, comprising:
- conducting a coolant through a cooling module via connections to the cooling module, wherein the cooling module is in thermal contact with the vehicle control unit and comprises:
- a cooling element;
- a turbulence insert comprising at least a first set of cooling fins located on the cooling element;
- and
- at least one bimetal located in the cooling element and configured to displace the first set of cooling fins depending on a temperature-dependent change in shape of the at least one first bimetal,
- generating a turbulent flow of the coolant through the cooling module by means of the turbulence insert;
- and
- altering the volumetric flow rate of the coolant through the cooling module.
