Abstract
Abstract In a method and a system for cooling semiconductors submerged in a liquid, the semiconductors, one or several, are, together with the liquid, arranged in a tank connected to a heat exchanger. The heat transport from the semiconductors takes place by the latent heat of vaporization of the liquid, transferring the heat to the heat exchanger. The pressure in the system is substantially nonvarying.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
89 words
A method for cooling semiconductors in power sources, comprising submerging the semiconductors in a liquid, permitting the liquid to vaporize and pass to a heat exchanger, such that the latent heat of vaporization of said liquid transports the heat from said semiconductors to the surfaces of the heat exchanger by condensation, and maintaining the system substantially at atmosPheric pressure, wherein the heat transport takes place in a closed system by transferring the air in the heat exchanger to an inflatable bag as the vapor moves into the beat exchanger.
Claim 2
Independent Claim
89 words
A method for cooling semiconductors in power sources, comprising submerging the semiconductors in a liquid, permitting the liquid to vaporize and pass to a heat exchanger, such that the latent heat of vaporization of said liquid transports the heat from said semiconductors to the surfaces of the heat exchanger by condensation, and maintaining the system substantially at atmosPheric pressure, wherein the heat transport takes place in a closed system by transferring the air in the heat exchanger to an inflatable bag as the vapor moves into the beat exchanger.
Claim 3
Dependent Claim
98 words
A cooling system for cooling semiconductors in power sources, comprising a substantially closed tank containing a liquid in which the semiconductors are submerged, a heat exchanger, means for passing liquid vapor from the tank to the heat exchanger and condensed liquid from the heat exchanger to the tank, and means for maintaining a generally uniform pressure in the system comprising an air outlet and inlet near the top of the heat exchanger through which air exits or enters as vapor enters from and returns to the tank, and an inflatable bag connected to said air outlet and inlet.
Claim 4
Dependent Claim
98 words
A cooling system for cooling semiconductors in power sources, comprising a substantially closed tank containing a liquid in which the semiconductors are submerged, a heat exchanger, means for passing liquid vapor from the tank to the heat exchanger and condensed liquid from the heat exchanger to the tank, and means for maintaining a generally uniform pressure in the system comprising an air outlet and inlet near the top of the heat exchanger through which air exits or enters as vapor enters from and returns to the tank, and an inflatable bag connected to said air outlet and inlet.
