Abstract:

A study was made of the problems of design and construction of Peltier temperature-control devices for use with Ordnance electronics. The principal features sought were 1 compatibility with conventional power supplies, particularly single-cell electrochemical systems, 2 techniques of assembly that are versatile with respect to physical configurations, and 3 techniques of assembly that are readily adaptable to production. A device for cooling was designed, built, and tested that operates from a supply voltage of 1.5 to 2.0 v at input powers up to about 6 w. Eighteen thermoelectric couples were connected in series electrically and in parallel thermally. Aluminum was used as the structural material, serving as both the base and the temperature-controlled chamber. An anodized layer on the aluminum provided good electrical insulation and thermal contact between the structural materials and thermoelectric elements. The circuit patterns were placed on the anodized layer by printed-circuitry techniques. By using jigs that are adaptable to quantity production, all 72 solder joints connecting the elements in series and to the structural materials were made in two operations. Author
