Abstract

This invention is about a cold energy thermoelectric power generation apparatus, which is based on thermoelectric couple assemblies with small temperature difference, so that thermoelectric couples function with light load and high efficiency, with greatly extended service life, furthermore, it is not necessary to use an air radiator or circulating cooling water system as in a traditional thermoelectric generator, therefore the flow setup is simpler; by using the cold recovery and circulation technology, the cold energy in the recovered liquefied gas can be used for power generation, the utilization rate of useful cold energy, or cold energy lian can be over 35%, and the equipment maintenance work quantity is substantially reduced as compared with a traditional thermoelectric generator, achieving quite significant economic, social, and environmental protection benefit, and it is a breakthrough to the traditional cold energy recovery technology.
