Abstract

This disclosure describes systems and methods for metal foam cooling of vehicle electronic. An example apparatus may include an electronic control unit (ECU) comprising an electronic component included within a housing. The example apparatus may also include a metal foam configured to dissipate heat produced by the electronic component and also configured to facilitate electromagnetic interference (EMI) shielding for the electronic component. The example apparatus may also include an interface between the ECU and the metal foam, wherein the interface provides a connection between the ECU and metal foam to facilitate heat dissipation from the electronic component to a location outside of the housing.

First claim

What is claimed is:

1. A vehicle comprising:
an electronic control unit (ECU) comprising an electronic component included within a housing; and
a metal foam configured to dissipate heat produced by the electronic component and also configured to facilitate electromagnetic interference (EMI) shielding for the electronic component; and
an interface between the ECU and the metal foam, wherein the interface provides a connection between the ECU and metal foam to facilitate heat dissipation from the electronic component to a location outside of the housing,
wherein the housing comprises at least one of: a plastic material or a metal material, and wherein the metal foam is in direct contact with the electronic component.

2. The vehicle of claim 1 , wherein the housing comprises a groove, wherein the metal foam comprises a protrusion extending from the metal foam, and wherein the direct contact is facilitated by an engagement between the protrusion and the groove.

3. The vehicle of claim 1 , wherein the interface comprises a thermal compound.

4. The vehicle of claim 1 , wherein the interface comprises a metal hook and fastener, wherein a first portion of the metal hook and fastener is affixed to the metal foam, and wherein a second portion of the metal hook and fastener is affixed to the housing.

5. The vehicle of claim 1 , wherein the metal foam is a first metal foam configured to facilitate heat dissipation from a first surface of the electronic component, and wherein the vehicle comprises a second metal foam configured to facilitate heat dissipation from a second surface of the electronic component.

6. An apparatus comprising:
an electronic control unit (ECU) comprising an electronic component included within a housing; and
a metal foam configured to dissipate heat produced by the electronic component and also configured to facilitate electromagnetic interference (EMI) shielding for the electronic component; and
an interface between the ECU and the metal foam, wherein the interface provides a connection between the ECU and metal foam to facilitate heat dissipation from the electronic component to a location outside of the housing,
wherein the metal foam is a first metal foam configured to facilitate heat dissipation from a first surface of the electronic component, and wherein the apparatus comprises a second metal foam configured to facilitate heat dissipation from a second surface of the electronic component.

7. The apparatus of claim 6 , wherein the housing comprises a plastic material, wherein the interface comprises a portion of the metal foam that is embedded within the housing, and wherein the metal foam is in direct contact with the electronic component.

8. The apparatus of claim 7 , wherein the housing comprises a groove, wherein the metal foam comprises a protrusion extending from the metal foam, and wherein the direct contact is facilitated by an engagement between the protrusion and the groove.

9. The apparatus of claim 6 , wherein the housing comprises a metal material, and wherein the interface comprises a portion of the metal foam that is in direct contact with the housing.

10. The apparatus of claim 6 , wherein the interface comprises a thermal compound.

11. The apparatus of claim 6 , wherein the interface comprises a metal hook and fastener, wherein a first portion of the metal hook and fastener is affixed to the metal foam, and wherein a second portion of the metal hook and fastener is affixed to the housing.

12. A system comprising:
an electronic control unit (ECU) comprising an electronic component included within a housing; and
a metal foam configured to dissipate heat produced by the electronic component and also configured to facilitate electromagnetic interference (EMI) shielding for the electronic component; and
an interface between the ECU and the metal foam, wherein the interface provides a connection between the ECU and metal foam to facilitate heat dissipation from the electronic component to a location outside of the housing,
wherein the interface comprises a metal hook and fastener, wherein a first portion of the metal hook and fastener is affixed to the metal foam, and wherein a second portion of the metal hook and fastener is affixed to the housing.

13. The system of claim 12 , wherein the housing comprises a plastic material, wherein the interface comprises a portion of the metal foam that is embedded within the housing, and wherein the metal foam is in direct contact with the electronic component.

14. The system of claim 12 , wherein the housing comprises a metal material, and wherein the interface comprises a portion of the metal foam that is in direct contact with the housing.

15. The system of claim 14 , wherein the housing comprises a groove, wherein the metal foam comprises a protrusion extending from the metal foam, and wherein the direct contact is facilitated by an engagement between the protrusion and the groove.

16. The system of claim 12 , wherein the interface comprises a thermal compound.
