Abstract
To cool electronic heat producing elements and components which are normally connected to a heat sink, an evaporator containing a circulating coolant is thermally connected to each of the heat producing components. The evaporator absorbs the heat from the heat producing element. The coolant is boiled or evaporated within the evaporator. The pressure on the gas produced by the evaporation is maintained at a constant pressure. This will result in a uniform temperature of the liquid as it is being evaporated. The heat producing components, therefore, will be maintained at substantially a constant temperature. Several heat producing elements may be connected to a single evaporator. For retrofitting existing units, individual evaporators are made to attach to the heat sink between the heat producing component and the heat sink. If the housing is made air tight, then a circulating fan, circulating air within the enclosed housing will remove heat from other heat producing sources within the cabinet and transfer it to the heat sink, which will in turn transfer it to the evaporator pads.
