[0002] A plate heat exchanger is a new type of efficient heat exchanger formed by stacking a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat exchange is carried out through the plates. The plate heat exchanger is an ideal device for heat exchange between liquid-liquid and liquid-vapor.

[0003] An existing detachable and efficient plate heat exchanger (Publication No.: CN219977191U) has at least the following drawbacks: When disassembling and repairing the heat exchange plates, it is still necessary to remove the clamping plate on the back of the device before the middle heat exchange plates can be replaced and disassembled. Moreover, when replacing the middle heat exchange plates, a pulling action is required, which easily causes displacement of the undamaged heat exchange plates on both sides, resulting in a decrease in the sealing performance between the heat exchange plates and increasing the maintenance workload, which is very troublesome.
