Thermoelectric generation module based on flat plate heat pipes and heat pipe circulation waste heat thermoelectric generation system formed by thermoelectric generation module based on flat plate heat pipes

Abstract

The invention discloses a thermoelectric generation module based on flat plate heat pipes and a heat pipe circulation waste heat thermoelectric generation system formed by the thermoelectric generation module based on the flat plate heat pipes. The thermoelectric generation module based on the flat plate heat pipes comprises a thermoelectric generation unit, a shell and a fan. Multiple groups of porous parallel flow flat pipes are arranged in the thermoelectric generation unit in parallel. The left and right sides of the porous parallel flow flat pipes are closely provided with thermoelectricgeneration pieces and heat radiation fins in turn. The upper and lower ends of the porous parallel flow flat pipes are inserted into a gas collection pipe and a liquid collection pipe so as to form the integrated thermoelectric generation module. Multiple groups of thermoelectric generation modules and a waste heat pipeline internal heat exchanger, a gas pipeline and a liquid pipeline can form theheat pipe circulation waste heat thermoelectric generation system, and the waste heat in the pipeline can be efficiently transmitted to all the thermoelectric generation modules for power supply through gravity heat pipe circulation. The scheme has the advantages of high generation efficiency, stable voltage, flexible and convenient to design and install and high in expansibility, and standardization, modularization and productization of the thermoelectric generation device can be facilitated.

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-...
