Abstract

The invention discloses a thermoelectric power generation module based on a flat heat pipe and a heat pipe cycle waste heat thermoelectric power generation system composed of the same, wherein the thermoelectric power generation module based on a flat heat pipe includes a thermoelectric power generation unit, a casing and a fan, and several groups of thermoelectric power generation units are arranged in parallel Multi-hole parallel flow flat tube, the left and right sides of the multi-hole parallel flow flat tube are tightly installed with thermoelectric power generation sheets and heat dissipation fins, and the upper and lower ends of the multi-hole parallel flow flat tube are respectively inserted into the gas header and liquid header to form an integrated thermoelectric power generation module . Several groups of thermoelectric power generation modules, heat exchangers in waste heat pipelines, gas pipelines, and liquid pipelines can form a heat pipe cycle waste heat thermoelectric power generation system. Through gravity heat pipe circulation, the waste heat in the pipeline is efficiently transferred to each thermoelectric power generation module for power generation. This solution has the advantages of high power generation efficiency, stable voltage, flexible and convenient design and installation, and strong scalability, and is conducive to the standardization, modularization, and commercialization of thermoelectric power generation devices.

Description

Technical field: [0001] The invention relates to a thermoelectric power generation module based on a flat heat pipe and a heat pipe cycle waste heat thermoelectric power generation system formed thereof, belonging to the technical field of waste heat recovery and utilization and thermoelectric power generation. Background technique: [0002] With the development of industrialization and the improvement of people's living standards, my country's energy consumption is increasing rapidly, and the problems of energy crisis and environmental pollution are becoming increasingly serious. Reducing energy consumption, improving energy utilization efficiency, and making full use of waste heat have become the only way for my country's energy development. There is a large amount of waste heat in industrial production, building environment construction, and domestic wastewater, and a large amount of cold energy is released in the process of liquefied natural gas gasification. These high-...
