Description

Technical Field

[0001] The utility model belongs to the technical field of brazed plate heat exchangers, and particularly relates to a brazed plate heat exchanger and its connection mechanism. Background Technique

[0002] The brazed plate heat exchanger is a new type of high-efficiency heat exchanger formed by stacking a series of metal sheets with a certain corrugated shape and then undergoing brazing processing. Thin rectangular channels are formed between various plate sheets, and heat exchange is carried out through the plate sheets. Compared with the conventional shell-and-tube heat exchanger, under the same flow resistance and pump power consumption, its heat transfer coefficient is much higher, and there is a trend to replace the shell-and-tube heat exchanger within the applicable range.
