The invention provides a plate heat exchanger and a heat exchange system thereof. The plate heat exchanger includes a front end plate, a rear end plate, and a plurality of heat exchange fins located between the front end plate and the rear end plate. A heat exchange channel is formed between two adjacent heat exchange fins, and a fluid flow channel is arranged on the front end plate. Inlet, the plate heat exchanger also includes: a fluid connection; an acceleration structure, the acceleration structure has a first liquid passage hole, an acceleration inner cavity and a second liquid passage hole, the first liquid passage hole communicates with the fluid connection pipe, and the second liquid passage hole communicates with the fluid connection pipe. The fluid inlet is connected; wherein, the acceleration inner cavity includes a first sub-inner cavity and a second sub-inner cavity that communicate with each other, and the first sub-inner cavity and the second sub-inner cavity are arranged at intervals along the flow direction of the two-phase fluid in the acceleration structure; along the second In the direction from the first liquid passage hole to the second liquid passage hole, the cross-sectional area of the first sub-inner chamber gradually decreases, and the cross-sectional area of the second sub-inner chamber gradually increases. The invention solves the problem of uneven distribution of the two-phase fluid in the flow channel of the plate heat exchanger in the prior art.
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...
