Properties of Heat dissipation under vacuum

Properties of Heat dissipation under vacuum

(OP)
Curious if anyone can point me to some info on how heat dissipates under vacuum.  Think in terms of a chamber full of warm silicon wafers and how that heat would dissipate.  Would it be signifigantly slower than at atmosphere?  Thanks  

RE: Properties of Heat dissipation under vacuum

There's still radiation of energy.  

Planck's blackbody function describes the problem.

Time is dependent on how the wafers are supported.  If they are on a planetary, there is some amount of conduction, and without air, there is no convection.

Ah interesting thanks for the reply...to correct my first post: "Think in terms of a chamber full of warm silicon wafers at .1 mT and how that heat would dissipate."

RE: Properties of Heat dissipation under vacuum

Assuming little physical contact, then it's all blackbody radiation, which may be quite poor in some vacuum chambers, since the inner walls might be highly reflective.
