Abstract

The invention discloses a multi-flow tandem type plate heat exchanger and relates to the heat exchanger technology field. The heat exchanger comprises a heat exchanger main body and an electronic expansion valve. A refrigerant inlet and a refrigerant outlet are arranged in a refrigerant side of the heat exchanger main body, and a water inlet and a water outlet are arranged in a refrigerating fluidside of the heat exchanger main body. The heat exchanger main body comprises a plurality of plate-type laminations and a plurality of partition plates, and each partition plate is arranged between every two adjacent plate-type laminations. The plurality of plate-type laminations and the plurality of partition plates are connected in series to form a multi-flow refrigerant side and a refrigerant liquid side. Through designing and optimizing a flow number of the refrigerant side and the flow number of the refrigerating fluid side, a series connection mode is adopted in multiple flows and structural parameters of the plates are optimized, heat exchange efficiency of the plate-type laminations is improved, power consumption of a water pump and the like in a cooling subsystem can be reduced, and meanwhile the power consumption of a compressor can be reduced.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a multi-flow series plate heat exchanger. Background technique [0002] Plate heat exchanger is a commonly used heat exchanger, which can be used for refrigerant-refrigerant heat exchange and water-water heat exchange. Compared with the tube-and-tube heat exchanger and shell-and-tube heat exchanger with the same function, the plate heat exchanger obviously has high heat exchange efficiency and light weight. The plate laminations of the existing plate heat exchangers have the following defects: most of them are in one process, and the heat exchange efficiency is not high. Contents of the invention [0003] In order to solve the problems of the prior art, the present invention provides a plate heat exchanger with high performance and high compressive strength, optimizes the number of processes on the refrigerant side and the number of processes on the refrigerant side th...
