Abstract

The disclosed component module includes a component comprising at least one electric contact to which at least one porous contact piece is connected; the component module further includes a cooling system for fluid-based cooling, said cooling system comprising one or more cooling ducts which are formed by pores of the porous contact piece. The disclosed power module comprises a component module of said type.

Claims (22)

1. A component module comprising:

a heat generating power component directly connected to at least one electrical contact, the at least one electrical contact being an electrically conductive film-like layer, in which a first surface of an open-pore electrical contact piece is connected to the at least one electrical contact and a second surface of the open-pore electrical contact piece opposite the first surface is connected to a substrate, such that there are no heat generating devices disposed between the second surface of the open-pore electrical contact piece and the substrate, wherein the open-pore electrical contact piece is formed by a fabric-like structure, a foam-like structure, a mesh-like structure, stacked leadframes, or any combination thereof; and

a cooling system for cooling using a cooling fluid, the cooling system comprising one or more cooling ducts that are formed by pores of the open-pore electrical contact piece.

2. The component module of claim 1 , wherein the open-pore electrical contact piece is connected electrically, by sintering, by soldering, by diffusion soldering, by pressing, by clamping, by adhesive bonding, or any combination thereof.

3. The component module of claim 1 , further comprising at least one integrated circuit, wherein the open-pore electrical contact piece is connected to the at least one integrated circuit.

4. The component module of claim 1 , further comprising a printed circuit board that has at least two or more components each jointly connected to the printed circuit board by an open-pore electrical contact piece.

5. The component module of claim 1 , wherein the open-pore electrical contact piece is formed from or by metal.

6. The component module of claim 5 , wherein the metal is nickel, silver, gold, tin, copper, or any combination thereof.

7. The component module of claim 1 , wherein the cooling fluid is formed by water, another cooling liquid, or water and the other cooling liquid.

8. The component module of claim 1 , wherein the cooling system comprises a heat pipe.

9. A power module comprising:

a component module comprising:

a heat generating power component directly connected to at least one electrical contact, the at least one electrical contact being an electrically conductive film-like layer, in which a first surface of an open-pore electrical contact piece is connected to the at least one electrical contact and a second surface of the open-pore electrical contact piece opposite the first surface is connected to a substrate, such that there are no heat generating devices disposed between the second surface of the open-pore electrical contact piece and the substrate, wherein the open-pore electrical contact piece is formed by a fabric-like structure, a foam-like structure, a mesh-like structure, stacked leadframes, or any combination thereof; and

a cooling system for cooling using a cooling fluid, the cooling system comprising one or more cooling ducts that are formed by pores of the open-pore electrical contact piece.

10. The power module of claim 9 , wherein the at least one component is a power component.

11. The power module of claim 9 , wherein the open-pore electrical contact piece is connected electrically, by sintering, by soldering, by diffusion soldering, by pressing, by clamping, by adhesive bonding, or any combination thereof.

12. The power module of claim 9 , wherein the component module further comprises at least one integrated circuit, wherein the open-pore electrical contact piece is connected to the at least one integrated circuit.

13. The power module of claim 9 , wherein the component module further comprises a printed circuit board that has at least two or more components each jointly connected to the printed circuit board by an open-pore electrical contact piece.

14. The power module of claim 9 , wherein the open-pore electrical contact piece is formed from or by metal.

15. The component module of claim 14 , wherein the metal is a copper sponge.

16. The power module of claim 9 , wherein the cooling fluid is formed by water, another cooling liquid, or water and the other cooling liquid.

17. The power module of claim 9 , wherein the cooling system comprises a heat pipe.
