Description

Technical Field

[0001] The utility model relates to the field of plate heat exchangers, in particular to a plate heat exchanger for enabling liquid to flow quickly. Background Technique

[0002] A plate heat exchanger is a highly efficient heat exchanger formed by stacking a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plate sheets, and heat exchange is carried out through the plate sheets. The plate heat exchanger is an ideal device for heat exchange between liquid and liquid, and between liquid and steam. It has the characteristics of high heat exchange efficiency, small heat loss, compact and lightweight structure, small floor area, wide application, long service life, etc. Under the same pressure loss condition, its heat transfer coefficient is 3-5 times higher than that of a tubular heat exchanger, the floor area is one-third of that of a tubular heat exchanger, and the heat recovery rate can be as high as more than 90%.

[0003] In the existing plate heat exchanger, the water passing angular holes on the heat exchange plate sheets are usually circular. When water flows through the circular angular holes and flows onto the plate surface, the resistance is too large and the loss also increases, and it is difficult to meet some harsh working conditions. The fluid is not evenly distributed during flow and cannot be better divided, reducing the heat exchange effect. Content of the Utility Model
