With a 50 volt unregulated rail, the channel dissipates
100 watts. It can also be set up to dissipate 67 watts
with lesser bias. This means a .25 deg C /watt seat
sink for each channel with the 100 watt setting.

The prototype sink was 13" deep with 1" fins spaced at
.3 inches and a 4 inch height. It is not really adequate
for the 100 watt dissipation (although if you arrange for
a breeze, it is). For the 100 watt figure, a 6 or 8 inch
height would about do it.
