THERMOELECTRIC GENERATOR USING WASTE HEAT

摘要

The present invention relates to a thermoelectric generator using waste heat, and more specifically, relates to a thermoelectric generator using waste heat, allowing low temperature parts of thermoelectric modules to indirectly be cooled by radiation members without being in direct contact with air in a state that the thermoelectric modules are blocked from the outside such that the temperature difference between each high temperature part and each low temperature part is rapidly generated, thereby improving the performance of thermoelectric generation. The thermoelectric generator using waste heat comprises: a heat exchanger pipe, a plurality of heat transfer members, thermoelectric modules, radiation members and a blocking pipe. The heat exchange pipe allows waste heat to pass therein. The heat transfer members are installed on the outer surface of the heat exchange pipe. The thermoelectric modules are installed on the outer surface of the thermoelectric member to allow the high temperature parts to be in contact with the thermoelectric member and allow the waste heat to be transferred to the high temperature parts. The radiation members are installed on the lower temperature parts of the thermoelectric modules, respectively, to cool the lower temperature parts of the thermoelectric modules. The blocking pipe is circularly installed along the radiation members at a predetermined distance from the heat exchange pipe to allow air to fill in each inner space between the radiation members and form a blocking space separating the thermoelectric modules from the outside such that the thermoelectric modules are prevented from being in direct contact with air, thereby securing a temperature difference between the high temperature part and low temperature part.
