Abstract
Abstract A thermoelectric apparatus is formed of a plate of heatinsulating material having holes therethrough in which are positioned a plurality of P-type and N-type thermoelectric elements. The members of the two types are alternately connected by heat-transfer members on both sides of the plate and in contact with the elements. Bolts extending through the thermoelectric elements connect two of the heat-transfer members and press them against the elements.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
139 words
Thermoelectric apparatus having a plate of heat-insulating material and a plurality of P-type and N-type semiconductor thermoelectric elements, said plate having a plurality of holes in which said elements are disposed, said elements having a dimension perpendicular to said plate at least equal to the thickness of said plate, a plurality of electrically conducting heat-transfer members on each side of said plate for transfer of heat between the elements and a fluid medium and in good electric and thermal pressure contact with said elements, said members connecting said P-type and N-type elements alternately in electrical series relationship, a current source connected to two of said members, and clamping means adjacent each of said elements engaging and pressing two of said members against the ends of each element, whereby said members, together with said elements, form an essentially self-supporting structure.
Claim 2
Dependent Claim
