Abstract
Abstract A thermal interface adapter is provided which is located in the interface between the housing and the heat sink of a conduction cooling module of the type which provides a conduction heat transfer path for removing heat from electronic components. The thermal interface adapter creates an interface between the housing and the adapter, and the adapter and the heat sink. The thermal interface adapter and interfaces associated therewith have a predetermined thermal resistance thereby increasing the heat transfer path thermal resistance to allow the thermal components within the module to operate at a higher temperature.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
140 words
In a conduction cooling module of the type having a conduction heat transfer path for removing heat from electronic components comprising: a plurality of electronic components to be cooled within said module at least one of which is low-power electronic component and at least one of which is a high-power electronic component; a housing member included in the heat transfer path; a heat sink adapted for connection to said housing for removing the heat therefrom; a thermal interface adapter located in the interface between said housing and said heat sink; said thermal interface adapter having a predetermined thermal resistance and having cut-out portions therein opposite said low power electronic components thereby causing local increases in thermal resistance as a function of the amount of cut-out thereby causing said low-power electronic components within the module to operate at a higher temperature.
Claim 2
Dependent Claim
140 words
In a conduction cooling module of the type having a conduction heat transfer path for removing heat from electronic components comprising: a plurality of electronic components to be cooled within said module at least one of which is low-power electronic component and at least one of which is a high-power electronic component; a housing member included in the heat transfer path; a heat sink adapted for connection to said housing for removing the heat therefrom; a thermal interface adapter located in the interface between said housing and said heat sink; said thermal interface adapter having a predetermined thermal resistance and having cut-out portions therein opposite said low power electronic components thereby causing local increases in thermal resistance as a function of the amount of cut-out thereby causing said low-power electronic components within the module to operate at a higher temperature.
Claim 3
Dependent Claim
56 words
In a conduction cooling module according to claim 1, wherein said low-power electronic components are arranged in one or more groups within the module and said thermal interface adapter cutout sections each corresponds in shape and size to a corresponding group and is located adjacent thereto in the heat transfer path associated with the respective group.
Claim 4
Dependent Claim
53 words
In a conduction cooling module according to claim 1, wherein said thermal interface adapter is made of polycarbonate of sufficient thickness and having enough contact area with said housing and heat sink to keep the thermal resistance within a predetermined range thereby maintaining the electronic components to be cooled within thermal operating limits.
Claim 5
Dependent Claim
18 words
In a conduction cooling module according to claim 1, wherein said thermal interface adapter is made of teflon.
Claim 6
Dependent Claim
18 words
In a conduction cooling module according to claim 1, wherein said thermal interface adapter is made of mica.
