A kind of pulsating heat pipe heat exchanger and its processing method

Abstract

The invention provides a pulsating heat pipe (PHP) heat exchanger and a machining method thereof. The machining method mainly comprises S1, installation steps of basic heat exchange units that positioning tubes are made to penetrate into vertical heat exchange branch tubes to the middle positions and are fixed; separation plates are put into the vertical heat exchange branch tubes at the two ends of each positioning tube, and the basic heat exchange units are formed; S2, installation steps of heat exchange units that fins are fixed to the vertical heat exchange branch tubes at the outer sides of the separation plates by adopting fixing components, and the heat exchange units are formed; and S3, installation steps of effective heat exchange substrates that the two ends of each vertical heat exchange branch tube are inserted into a first horizontal tube group and a second horizontal tube group separately, and joint points are all welded in a high-silver welding mode; neighboring separation plates are connected; neighboring horizontal tubes in the first horizontal tube group and the second horizontal tube group are connected through elbows, and the vertical heat exchange branch tubes and all the horizontal tubes are connected to be a return circuit. The machining method is simple in technology, suitable for mass production, and the PHP heat exchanger machined through the machining method is good in reliability.

Description

technical field [0001] The invention relates to a pulsating heat pipe technology, in particular to a pulsating heat pipe heat exchanger and a processing method thereof. Background technique [0002] Most of the current heat exchangers are partition wall heat exchangers, mainly including shell-and-tube heat exchangers, plate heat exchangers and tube-fin heat exchangers. The plate heat exchangers are widely used due to their compact structure and high heat transfer coefficient. more extensive. However, partition wall heat exchangers generally have the defects of difficult sealing and difficult processing, and the processing time is long and the process is complicated, resulting in relatively high cost. , once leaked, it will cause the mixing of hot and cold fluids, which will bring hidden dangers to the safe operation of the heat exchange system. [0003] The current partition wall heat exchanger has defects such as difficult sealing, difficult processing, long processing cy...
