Claims: What we claim is:

1. A thermoelectric module having a hot junction and a cold junction and having a heat-transfer assembly at its hot junctions, said assembly including a pair of metallic heat-conducting plates having compressed therebetween a thermally conducting and electrically insulating member, said member being coated on each side with a thermally-conducting layer of material which does not diffusion bond to the member and permits separation of the plates.

2. The module of claim 1 wherein each of the plates is composed of a corrosive resistant nickel-base alloy, the member is composed of alumina and the layers are composed of gold.

3. In a generator including a heat source, a thermoelectric module having a hot junction and a cold junction, and a heat sink including a thermally conducting plate through which heat is dissipated to fins, the improvement which consists of a shock-mount support for said module interposed between said cold junction and said plate, said support including resilient means urging said hot junction into effective heat-exchange relationship with said heat source, said support also including deformable highly-thermally conducting means thermally connecting said cold junction and said plate and providing a deformable highly-thermally conducting path from said cold junction to said plate, said deformable means being spaced from said resilient means, said deformable means consisting of crinkled copper strips.
