Abstract

A described cooling system uses high junction temperature components in a processor to cool low junction temperature components of the same processor by using waste heat from one set of electronic components to cool another set of electronic components utilizing the concept of Dalton's law of partial pressures. As seen in the drawing, waste heat from electronic components operating at high junction temperature, such as processor power supplies, are used to drive a vapor generator 1, which is a heat exchanger. Inside the vapor generator 1 there is a binary mixture, e.g., NH3 and H2O. Because the NH3 has a lower boiling temperature, its vapor, containing H2O particles, will pass through a percolator tube 2.
