This will result in a rise in temperature which may cause overheating of and possible damage to the engine as well as to the heat source itself. The invention provides a support/location member for conducting excess heat from the heat source and which, in normal operation of the engine, will impede the conduction of heat away from the heat source and so reduce thermal losses. The member is of elongated form and comprises a stack of heatconductive slugs disposed in a tube and in interspaced relationship along the axis of the tube. The tube supports the slugs in axial alignment. Means are provided for attaching an end one of the slugs to the heat source and means operable on overheating of said end one of the slugs are also provided whereby the slugs are able to move into heat-conducting contact with each other so as to conduct the excess heat away from said heat source. The slugs may be brazed to the tube whereby progressive overheating of the slugs along the stack results in an overheated slug being freed from attachment to the tube so as to allow the overheated slug to move along the stack and engage the next slug in line in heat-conducting contact.,下面是Member for conducting excess heat away from heat sources专利的具体信息内容。

1. A MEMBER FOR CONDUCTING HEAT FROM A HEAT SOURCE, SAID MEMBER BEING OF ELONGATED FORM AND COMPRISING A STACK OF HEAT-CONDUCTIVE SLUGS DISPOSED IN INTERSPACED RELATIONSHIP ALONG THE LONGIUDINAL AXIS OF THE MEMBER, SLUG SUPPORT MEANS FOR LOCATING THE SLUGS IN AXIAL ALIGNMENT, MEANS FOR ATTACHING AN END ONE OF THE SLUGS TO THE HEAT SOURCE AND MEANS PERABLE
2. A member as claimed in claim 1 having fusible attachment means for attaching the slugs to the slug support means.
3. A member as claimed in claim 1 provided with means for biasing the slugs towards contact with each other.
4. A member as claimed in claim 3 wherein said slugs are hollow and the means for biasing the slugs towards contact with each other comprise a tie-member attached to said end one of the slugs and extending through the stack of slugs and means for applying tension to said tie-member.
5. A member as claimed in claim 1 provided with means for biasing the slugs towards contact with each other and further provided with counter-acting means for biasing the slugs apart.
6. A member as claimed in claim 5 wherein the slugs and hollow and an elongated compression member extends through the stack of slugs to act against said one end of the slugs, the member being further provided with means for applying a compression force to said compression member.
7. A member as claimed in claim 6 wherein a body of fusible material is disposed between the end of the compression member adjacent said end one of the slugs and said end one itself.
8. A member as claimed in claim 1 wherein the slug support means comprise a tubular member.
9. A member as claimed in claim 1 wherein the slug support means comprise a resilient frame located by the bore of a tubular member.
