Abstract

The invention provides a plate heat exchanger and a heat exchange system with the same. The plate heat exchanger comprises a front end plate, a rear end plate and a plurality of heat exchange sheets located between the front end plate and the rear end plate. A heat exchange flow channel is formed between every two adjacent heat exchange sheets. A fluid inlet is formed in the front end plate. The plate heat exchanger further comprises annular distribution structures which are arranged opposite to the fluid inlets and located in the heat exchange flow channels. The two ends of each annular distribution structure are connected with the two corresponding heat exchange sheets correspondingly. Each annular distribution structure comprises a plurality of distribution holes formed in the inner circumferential face of the annular distribution structure at intervals. Each distribution hole penetrates through the inner wall and the outer wall of the corresponding annular distribution structure. The multiple annular distribution structures and the multiple heat exchange flow channels are arranged in a one-to-one correspondence manner. The plate heat exchanger and the heat exchange system with the same effectively solve the problem that in the prior art, two-phase fluid of a plate heat exchanger is not evenly distributed in flow channels.

Description

technical field [0001] The invention relates to the technical field of plate heat exchangers, in particular to a plate heat exchanger and a heat exchange system having the same. Background technique [0002] At present, the plate heat exchanger is a new type of high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape. It has high heat transfer efficiency, light weight, small footprint, compact structure, and easy maintenance. Advantages, widely used in the field of air conditioning. Specifically, the main reason affecting the performance of the plate heat exchanger is the uneven distribution of the two-phase fluid between the flow channels. The fluid inlet side is usually a gas-liquid two-phase mixture. In the flow channel where the liquid phase fluid is less distributed, the fluid advances " "Evaporate to dryness", the heat transfer effect becomes poor; in the channel where the liquid phase fluid is distributed more, the evaporati...
