Abstract
A combined electronics mounting plate and heat exchanger and method of manufacturing same. The present invention provides an electronics mounting plate formed from a metal matrix composite and a metal heat exchanger in order to combine the low coefficient of thermal expansion and high heat dissipation characteristics of a metal matrix composite, with the cost effectiveness and relatively easy manufacturability of metal. In the preferred embodiment, the metal matrix composite is provided in the form of aluminum and silicon carbide, and the metal heat exchanger is provided in the form of aluminum fins. The method of manufacturing the present invention includes the steps of cleaning the metal matrix composite mounting plate and aluminum heat exchanger in a nitric acid fluoride salt before brazing the elements together. In one embodiment of the present invention the metal matrix composite mounting plate includes pin fins extending toward the aluminum heat exchanger fins, and an additional aluminum braze sheet is provided between the mounting plate and heat exchanger fins to enhance the brazement therebetween and improve the thermal conductivity of the resulting mounting plate and heat exchanger.
