Plate type heat exchanger with pulsating heat pipes

Abstract

The invention relates to a plate type heat exchanger with pulsating heat pipes. The pulsating heat pipes are arranged on heat exchange plates of the heat exchanger and are integrated with the heat exchange plates, accordingly, heat exchange efficiency of the heat exchanger is effectively improved under joint effects of forced convection heat transfer, phase-change heat transfer of the pulsating heat pipes and enhanced heat transfer of pulsating flowing, and the novel high-efficiency plate type heat exchanger with the pulsating heat pipes is formed. The plate type heat exchanger is mainly used for places relevant to heat exchange including ships, automobiles, aerospace, aviation, electronics, motors, the nuclear industry, thermal engineering, buildings, medical treatment, temperature adjustment and waste heat recovery, utilization of solar energy and terrestrial heat, and the like. The plate type heat exchanger has the advantages that heat exchange efficiency is high, pressure loss is low, the temperatures of the heat exchange plates are uniform, scaling cannot be caused easily, and the like.

Description

technical field [0001] The invention relates to a plate type pulsating heat pipe heat exchanger, that is, pulsating heat pipes are arranged on the heat exchange fins of the heat exchanger, the pulsating heat pipes and the heat exchange fins are integrated, and the forced convection heat transfer and the phase change heat transfer of the pulsating heat pipes are combined with Under the joint effect of enhanced heat transfer of pulsating flow, the heat exchange efficiency of the heat exchanger is effectively improved, forming a new high-efficiency plate-type pulsating heat pipe heat exchanger. It is mainly used in occasions involving heat exchange such as ships, automobiles, aerospace, aviation, electronics, electrical machinery, nuclear industry, thermal engineering, construction, medical treatment, temperature regulation, waste heat recovery, and solar and geothermal utilization.

AI Technical Summary

Problems solved by technology

2) Corrosion and scaling problems, due to the shackles of surface treatment technology, shell and tube heat exchangers are more prone to corrosion and structural problems, and once corrosion and scaling occur, its maintenance and maintenance are troublesome, which greatly reduces its heat transfer efficiency

3) The contradiction between heat transfer efficiency and pressure loss. To improve the efficiency of shell and tube heat exchangers, it is often accompanied by the loss of fluid pressure

However, the plate heat exchanger also has the contradiction between heat exchange efficiency and pressure loss, and the plate heat exchanger is prone to fouling, which requires frequent cleaning and maintenance, otherwise its heat transfer efficiency will be greatly reduced. In addition, the plate heat exchanger The temperature difference between the inlet and outlet of the sheet is large, and the temperature on a single sheet is uneven, which will affect its performance
