Coupling heat to a metal case

[John Teller]

Bergquist (http://www.bergquistcompany.com) also sells several kinds of 
thermal transfer materials, in particular a heat-conductive material 
called Gap Pad.  You simply insert it in the space between an odd shaped 
hot part and its metal box, then tighten the mounting screws.  The Gap 
Pad fills the space and transfers the heat.

I think you can get samples if you send them a request from an email 
address other than aol.
