A parallel small-diameter heat pipe enhanced heat exchange device for recovering waste heat of medium and low temperature flue gas and its preparation method

Abstract

The invention relates to a parallel small diameter heat pipe enhanced heat exchange device for recovering medium and low temperature flue gas waste heat, aims to solve the problem of waste of medium and low temperature flue gas waste heat generated in small combustion equipment primarily, recovers the flue gas waste heat by means of parallel small diameter heat pipes to produce hot water or heat other substances, and is suitable for recovering waste heat of small flow flue gas or a discontinuous small flow heat source. The parallel small diameter heat pipe enhanced heat exchange device is primarily characterized in that the parallel small diameter heat pipe enhanced heat exchange device is good in heat transfer property, compact in structure, small in size, easy to process and low in cost,and can achieve self transfer of heat and efficient recovery of waste heat, so that the exhaust gas temperature is reduced greatly and the integral efficiency of the system is improved. The device isquite suitable for heat recovery of small capacity medium and low temperature flue gas waste heat and discontinuous waste heat resources, and a heating container is taken conveniently.

Description

technical field [0001] The present invention relates to a small-scale enhanced heat exchange device for recovering waste heat of medium and low temperature flue gas and performing efficient heat transfer and heat utilization and a preparation method thereof. The small-diameter heat pipe is used under the joint action of the heat source and the heated working medium to pass through the heating medium of the heat pipe. The phase change movement realizes the recovery of waste heat and the thermodynamic conversion and heat transfer of the working medium in the tube. It belongs to the field of two-phase flow high-efficiency heat transfer and waste heat recovery. Background technique [0002] At present, there are a large number of medium and low temperature waste heat resources in industrial, civil and commercial thermal equipment, among which the capacity of waste heat resources of civil and commercial thermal equipment is lower than that of large industrial waste heat resources...
