Abstract

In this cooling system, heat is transferred from circuit modules of a large computer to variable conductance heat pipes and thence to vertical heat transfer units, which may themselves be heat pipes or simple heat exchangers. In either case, the vertical heat transfer units can be cooled by utility water, such as from the ordinary water supply of the building in which the computer is located, without need for closely controlled chilled water for that purpose. The figure shows a representative layout of the system. Circuit modules 10, 12, 14, 16 requiring close temperature regulation are connected by horizontal heat pipe systems 18, 20 to vertical heat exchanger units 22, 24.

Heat Pipe Links for Water-Cooled Large Computer Circuit Assemblies

In this cooling system, heat is transferred from circuit modules of a large computer to variable conductance heat pipes and thence to vertical heat transfer units, which may themselves be heat pipes or simple heat exchangers. In either case, the vertical heat transfer units can be cooled by utility water, such as from the ordinary water supply of the building in which the computer is located, without need for closely controlled chilled water for that purpose. The figure shows a representative layout of the system. Circuit modules 10, 12, 14, 16 requiring close temperature regulation are connected by horizontal heat pipe systems 18, 20 to vertical heat exchanger units 22, 24. The vertical units 22, 24 can be heat pipe devices or ordinary fluid-cooled heat sinks, in either case arranged to deliver heat to building utility water supplied via pipes 26, 28 and discharged at 30, 32. The horizontal systems 18, 20 have pad elements 34 which conduct heat from the modules and pipe elements 36, 38 which convey the heat to sink elements 40 cooled by the vertical units 22, 24. The pipe elements and the interior of the pad and sink elements have stainless steel mesh linings which act as wicks for a water-alcohol liquid which is evaporated at 34 and condensed at 40 to provide a variable conductance heat pipe system. Expansion means, such as a gas reservoir (not shown) connected to the heat pipe system, maintains...
