摘要： A thermoelectric module (45) contains thermoelectric elements installed in a gapless eggcrate. An eggcrate having walls without gaps is formed using a technique such as injection molding. This gapless eggcrate provides insulated spaces for a large number of p-type and n-type thermoelectric elements. The absence of gaps in the walls of the spaces virtually eliminates the possibility of interwall shorts between the elements even when electrical connections are made by metal spray techniques. Fabrication of the gapless eggcrate can be automated using several available techniques such as molding and casting to greatly reduce the labor cost of fabricating thermoelectric eggcrates as compared to prior art techniques of fabricating eggcrates. Thermoelectric elements (45), both p-type and n-type, are fabricated and are inserted into the insulated spaces in the gapless eggcrate in a predetermined manner to provide the desired thermoelectric effects for a predetermined type of application. Electrical connections are established on both the hot and cold sides of the module to connect the thermoelectric elements in series or parallel as desired.

摘要： A long life, low cost, high-temperature, high efficiency thermoelectric module. Preferred embodiments include a two-part (a high temperature part and a cold temperature part) egg-crate and segmented N legs and P legs, with the thermoelectric materials in the three segments chosen for their chemical compatibility or their figure of merit in the various temperature ranges between the hot side and the cold side of the module. The legs include metal meshes partially embedded in thermoelectric segments to help maintain electrical contacts notwithstanding substantial temperature variations. In preferred embodiments a two-part molded egg-crate holds in place and provides insulation and electrical connections for the thermoelectric N legs and P legs. The high temperature part of the egg-crate is comprised of a ceramic material capable of operation at temperatures in excess of 500° C. and the cold temperature part is comprised of a thermoplastic material having very low thermal conductivity.
