Abstract

The invention provides a cascade phase change heat reservoir which comprises a box body, a plurality of first snakelike heat exchange pipes arranged in the box body and a plurality of second snakelike heat exchange pipes arranged in the box body. A partition plate is arranged in the box body, the interior of the box body is divided into a first cavity and a second cavity which are relatively independent by the partition plate, an inlet collecting pipe is arranged on one side of the top of the box body, an outlet collecting pipe is arranged on the other side of the top of the box body, one ends of the first snakelike heat exchange pipes communicate with the inlet collecting pipe, the other ends of the first snakelike heat exchange pipes communicate with one ends of the second first snakelike heat exchange pipes, and the other ends of the second first snakelike heat exchange pipes communicate with the outlet collecting pipe. The second cavity is filled with a second phase change heat storage medium. According to the cascade phase change heat reservoir, the problem that in the prior art, a snakelike pipe phase change heat exchanger conducts heat exchange through a single phase change material, and the heat exchange effect is poor is solved, design is reasonable, and the cascade phase change heat reservoir is suitable for production, popularization and application.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a cascade phase change heat storage device. Background technique [0002] There is a defect in the traditional serpentine tube phase change heat exchanger. The serpentine tube phase change heat exchanger performs heat exchange through a single phase change material without preheating or precooling, and the heat exchange effect is poor. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a cascaded phase change heat storage device, which is used to solve the problem that the serpentine tube phase change heat exchanger in the prior art uses a single phase change material for heat exchange without For preheating or precooling, the heat exchange effect is poor. [0004] In order to achieve the above purpose and other related purposes, the present invention provides a cascade pha...
