Abstract
A heat exchanger for cooling a heat-generating component includes first and second plates, each having a core layer of a first metal and an inner clad layer of a lower melting second metal, which is inert to the working fluid contained in a fluid chamber of the heat exchanger. The outer peripheral sealing surfaces of the first and second plates are joined by welding, wherein the weld joint is fluidly isolated from the fluid chamber by a layer of the second metal in an area adjacent to the weld joint. In some embodiments, the heat exchanger includes liquid flow passages and primary and secondary gas flow passages, each secondary passage providing communication between primary gas flow passages. The gas and liquid flow passages may be defined by a wick material having hydrophilic areas and non-wicking areas of reduced thickness. A method of manufacturing is also disclosed.
