Quick-response phase-change heat storage type heat exchanger

Abstract

The invention relates to a quick-response phase-change heat storage type heat exchanger. The quick-response phase-change heat storage type heat exchanger is characterized in that spaces between external sleeves and an internal pipeline are filled with phase-change capsules, and heat from heat exchange fluid in the internal pipeline can be absorbed by the aid of phase change of the phase-change capsules; the external sleeves wrap the internal pipeline and the phase-change capsules, and internal pipeline inlets and heating fluid flowing access openings are formed in the external sleeves. The phase-change capsules are replaceable phase-change capsules of corresponding temperatures and are arranged inside the quick-response phase-change heat storage type heat exchanger. The quick-response phase-change heat storage type heat exchanger has the advantages that the heat of the fluid in the internal pipeline can be absorbed by the phase-change capsules and can be utilized, and heat can be generated by the aid of continuous phase change of phase-change materials; the quick-response phase-change heat storage type heat exchanger is large in heat exchange area when the heat is released, the heat can be transferred by the aid of phase change, forced convection effects can be realized, a large quantity of heat can be released within a short time for heating the fluid, and accordingly problems of discontinuity of low-grade heat energy, difficulty in collecting the low-grade heat energy and low energy flow density can be solved; the quick-response phase-change heat storage type heat exchanger is simple and convenient, required heat exchange pipelines only need to be connected with internal pipeline access openings of the quick-response phase-change heat storage type heat exchanger, and the required-to-be-heated fluid only needs to be connected with external sleeve access openings of the quick-response phase-change heat storage type heat exchanger.

Description

technical field [0001] The invention relates to a heat exchanger used in a heat exchange system and realizing low-grade long-period rapid response heat exchange requirements. Background technique [0002] Up to now, there are many types of existing heat exchangers, which can meet different needs and be used in different occasions. However, in the low-grade, long-period regenerative type, there are few scientific research institutions. On the one hand, it is difficult to recover low-grade heat energy, and on the other hand, heat storage materials do not meet the energy storage requirements of low-grade heat energy. These defects limit the further research and development of low-grade long-cycle fast-response regenerative heat exchangers. [0003] Therefore, it is necessary to design a low-grade long-period fast-response heat exchanger, the purpose of which is: 1. The internal pipe is a heat exchange fluid channel to provide heat exchange heat. 2. Between the outer casing a...
