Heat exchanger and three-phase absorption type energy storage system

Abstract

The invention discloses a heat exchanger and a three-phase absorption type energy storage system. The heat exchanger comprises a solution input pipeline, a solution channel unit and a solution output pipeline which are sequentially connected in series, a water vapor pipeline communicating with the solution input pipeline, and a fluid input pipeline, a heat exchange channel unit and a fluid output pipeline which are sequentially connected in series. The solution channel unit comprises a plurality of solution channels which are connected in parallel; the heat exchange channel unit comprises a plurality of heat exchange channels which are connected in parallel; each solution channel is at least in contact with one heat exchange channel, and the cross sectional area of each solution channel is larger than that of each heat exchange channel. According to the heat exchanger, the solution channel and the heat exchange channel which are different in cross section area are adopted, on the premise that normal flowing of heat exchange fluid in the heat exchange channel is guaranteed, the cross section area of the solution channel is enlarged, crystals separated out of the solution are prevented from blocking the solution channel, and the heat exchange efficiency of the heat exchanger is improved. 本发明公开一种换热器及三相吸收式蓄能系统，所述换热器包括依次串联连接的溶液输入管道、溶液通道单元和溶液输出管道，与所述溶液输入管道连通的水蒸气管道，以及依次串联连接的流体输入管道、换热通道单元和流体输出管道；所述溶液通道单元包括并联连接的多个溶液通道；所述换热通道单元包括并联连接的多个换热通道；每个溶液通道至少与一个换热通道相接触，且溶液通道的横截面积大于换热通道的横截面积。本发明所述换热器采用具有不同横截面积的溶液通道与换热通道，在保证换热流体在换热通道内正常流动的前提下，扩大溶液通道的横截面积，避免溶液析出的晶体阻塞溶液通道，提升了所述换热器的换热效率。
