Abstract

919,147. Semi-conductor devices. GENERAL ELECTRIC CO. Ltd. Nov. 10, 1960 [Nov. 11, 1959 ; June 1, 1960 ; Oct. 3, 1960], Nos. 38242/59, 19470/60 and 33836/60. Class 37. Thermo-electric elements are connected together by casting the electrical connections directly into them. As shown in Fig. 2, bismuth telluride elements 7 are supported in an egg-box jig consisting of interlocking slotted elements 1, 3, 4. These elements may be of mica or of silicone-impregnated glass cloth. The assembly is supported on a castellated block 8 and pure tin 9 melted by high-frequency or radiant heating to connect the tops of the elements. The assembly is then inverted, the castellated block removed and the connecting process repeated. The ends of the thermoelectric elements may be nickel-coated to promote wetting by the tin. The insulating strips may be retained or removed, the assembly being impregnated with a bonding resin. After completion the tin is machined off to provide flat heat-conducting surfaces, as shown in Fig. 3. In the arrangement shown in Fig. 4, the bismuth telluride elements are held as a push-fit in trays 10 provided with spacing webs 11 and intersecting spacing webs of mica 12. Pure tin is cast on to the ends of the thermo-electric elements by feeding a tin wire 14 to a highfrequency heating zone. As in the previous embodiments the tin faces are machined flat.
