Abstract

The invention relates to a device for conducting a cooling fluid for cooling an electrical component. The device comprises a fluid conducting chamber for conducting the cooling fluid, and an at least partially flexible cover, which seals the fluid conducting chamber in a fluid-tight manner and which forms a heat transmission zone for conducting heat between the cooling fluid and the electrical component.

First claim

The invention claimed is:

1. A device for conducting a cooling fluid for cooling an electrical component, wherein the device has the following features:
a fluid-conducting chamber for conducting the cooling fluid;
side walls; and
an at least partially flexible cover, wherein the cover closes off the fluid-conducting chamber in a fluid-tight manner, wherein the cover comprises an edge region corresponding to the side walls, a heat-transfer region for conducting heat between the cooling fluid and the electrical component corresponding to a geometry of the electrical component, and a boundary region between the edge region and the heat-transfer region that is not covered by the electrical component, wherein the cover is inflexible in the boundary region, and is flexible in the heat-transfer region, wherein flexibility allows fluid pressure to cause deformation of the cover.

2. The device as claimed in claim 1 , in which the cover is a film or foil.

3. The device as claimed in claim 1 , in which the cover is formed from an electrically insulating material.

4. The device as claimed in claim 1 , in which a side of the cover which faces the electrical component is structured to increase the surface area of the heat-transfer region in comparison to a smooth cover.

5. The device as claimed in claim 1 , in which a side of the cover which faces the electrical component has an adhesive coating.

6. The device as claimed in claim 1 , in which the fluid-conducting chamber is connected to the cover in an interlocking manner and/or in a force-fitting manner and/or in a materially cohesive manner.

7. The device as claimed in claim 1 , in which the fluid-conducting chamber has an interior space having at least one partition wall for conducting the cooling fluid.

8. The device as claimed in claim 1 , in which the fluid-conducting chamber is also at least partially flexible.

9. A cooling system for cooling an electrical component, which cooling system has the following features:
the electrical component; and
a device as claimed in claim 1 , wherein the electrical component is arranged in the heat-transfer region of the cover of the device.

10. The device as claimed in claim 1 , wherein the heat-transfer region is a central region of the cover.

11. The device as claimed in claim 1 , wherein the edge region is inflexible.

12. A device for conducting a cooling fluid for cooling an electrical component, wherein the device has the following features:
a fluid-conducting chamber for conducting the cooling fluid;
side walls; and
an at least partially flexible cover, wherein the cover closes off the fluid-conducting chamber in a fluid-tight manner, wherein the cover comprises an edge region corresponding to the side walls, a heat-transfer region for conducting heat between the cooling fluid and the electrical component corresponding to a geometry of the electrical component, and a boundary region between the edge region and the heat-transfer region that is not covered by the electrical component, wherein the cover is inflexible in the boundary region and edge region, and is flexible in the heat-transfer region, wherein flexibility allows fluid pressure to cause deformation of the cover, wherein the heat-transfer region is a central region of the cover,
wherein the cover is a film or foil, wherein the cover is formed from an electrically insulating material, wherein a side of the cover which faces the electrical component is structured to increase the surface area of the heat-transfer region in comparison to a smooth cover, wherein a side of the cover which faces the electrical component has an adhesive coating.
