[Amps] LDMOS HEAT SPREADERS

[Steve]

Can't see why not with a bit of effort and ingenuity, and looks well 
worth the effort.

The same people list 'liquid chill plates' under the 'heat sinks' 
category. These look remarkably similar to ones Aavid advertise. While 
to cooling isn't quite so good, mounting the transistor and pcbs is 
easier. The typical package can sit in line with the pipes in between a 
pair or, if the fixing holes work out, crossways stradding two pipes.

Aavid prices aren't much different from buying a heat spreader and 
suitably large air cooled heatsink.
