Abstract
Abstract A semi-conductor cooling system formed of a container having a wall portion made of soft yieldable material which is adapted to contact the surface of a semi-conductor device. A porous member is disposed within the container adjacent the inner surface of the yieldable wall. A liquid medium partially fills the remainder of the chamber immersing at least a portion of the porous member. The latent heat of the semi-conductor device is dissipated via the porous member in a closed evaporator-condensing cycle.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
80 words
A method for cooling a semi-conductor device comprising the steps of subjecting the electrode face of said semi-conductor to contact with a yieldable wall of a container, placing a porous member within said container adjacent said yieldable wall and biasing said porous member against said yieldable wall, partially filling the container with a liquid medium in contact with said porous member and causing the heat of said electrode to be dissipated through said wall, said porous member and said liquid.
Claim 2
Independent Claim
80 words
A method for cooling a semi-conductor device comprising the steps of subjecting the electrode face of said semi-conductor to contact with a yieldable wall of a container, placing a porous member within said container adjacent said yieldable wall and biasing said porous member against said yieldable wall, partially filling the container with a liquid medium in contact with said porous member and causing the heat of said electrode to be dissipated through said wall, said porous member and said liquid.
Claim 3
Dependent Claim
32 words
The method according to claim 1 including the step of placing a second container having a yieldable wall partition, a porous member and a liquid adjacent the opposite face of said semi-conductor.
Claim 4
Dependent Claim
18 words
The method according to claim 1 including the step of yieldably biasing said porous member against said wall.
