Abstract

This is a method of making a cold plate heat exchanger for cooling a computer power supply, having a precise geometrical configuration using a superplastic metal such as 78% zinc 22% aluminum molded about a preformed cooling element. Significant advantages of the method are: the intimate contact between the tubes and the superplastic metal, ease of manufacture of local shapes, and a minimum loss of material.

Heat Exchanger Using Superplastic Alloy Process

This is a method of making a cold plate heat exchanger for cooling a computer power supply, having a precise geometrical configuration using a superplastic metal such as 78% zinc 22% aluminum molded about a preformed cooling element. Significant advantages of the method are: the intimate contact between the tubes and the superplastic metal, ease of manufacture of local shapes, and a minimum loss of material.

This heat exchanger consists of a coil 1 of copper tubing for coolant transport, partially enveloped as shown in solid lines, or totally enveloped, as shown in broken lines 2, in a sheet 3 of superplastic material that is formed thereabout while in the superplastic state. Holes 4, relief slots 5 for receiving resistors, and component mounting apertures 6 are all molded during the forming of the metal sheet.
