Abstract

A thermoelectric converter comprises a thermoelectric element assembly (10) composed of an array of P-type thermoelectric elements (12) and N-type thermoelectric elements (13) in a predetermined array pattern and heat-exchange element assemblies (20, 30) composed of heat-exchange elements (22, 32) and holding boards (21, 31) holding heat-exchange elements (22, 32) so as to hold the heat-exchange elements (22, 32) in a predetermined array pattern corresponding to the array pattern of the thermoelectric elements (12, 13). After stacking the thermoelectric element assembly (10) and the heat-exchange element assemblies (20, 30), joint portions between the thermoelectric element assembly (10) and the heat-exchange element assemblies (20, 30) are jointed with a jointing member at a time.

Description

technical field [0001] The invention relates to the technology of a thermoelectric conversion device in which an N-type thermoelectric element and a P-type thermoelectric element are connected in series. Background technique [0002] In the prior art, thermoelectric conversion devices described in Japanese Patent No. 3166228 (US Patent No. 5254178), Japanese Patent Application Laid-Open No. 5-175556 and US Patent No. 6521991 are widely known. [0003] In these prior art, a plurality of N-type thermoelectric elements and P-type thermoelectric elements are alternately connected in series. Their connected parts, under the action of the Peltier effect, become low temperature or high temperature according to the direction of current flow. The low temperature section is also referred to as "heat absorption section" or "cooling section". The high temperature portion is also referred to as a “radiation portion” or a “heating portion”. Furthermore, the above-mentioned prior ...
