Abstract

This paper systematically reviews the latest progress in the research on the integration of Printed Circuit Heat Exchanger (PCHE) and Thermoelectric Generation (TEG) technology. With the increasingly prominent issue of energy shortage, the efficient utilization of the large amount of cold energy released during the gasification process of Liquefied Natural Gas (LNG) has become a research hotspot in the energy field. As a new type of compact heat exchanger, the Printed Circuit Heat Exchanger shows great application potential in the field of LNG gasification due to its advantages of compact structure, high heat transfer efficiency, and high pressure resistance. The thermoelectric generation technology based on the Seebeck effect can directly convert thermal energy into electrical energy, providing an innovative solution for LNG cold energy recovery. This paper comprehensively analyzes the integrated innovation of PCHE and TEG technologies from the aspects of technical principles, structural design, performance optimization, and application fields, focuses on key issues such as composite structure design, heat transfer enhancement methods, and thermoelectric conversion characteristics, and looks forward to the challenges and future development trends of this technology. Research shows that the organic combination of PCHE and TEG can simultaneously achieve efficient gasification of LNG and cold energy power generation, providing a new idea for efficient energy utilization.
