Thin rectangular channels are formed between the various plates, and heat exchange occurs through the plates. Plate heat exchangers are ideal equipment for liquid-liquid and liquid-vapor heat exchange.
[0003] Based on the above, the inventors have discovered the following problems: the current method of manually adjusting the intermediate regulating plate of the symmetrical plate heat exchanger has many shortcomings. The adjustment force is not easy to control. When the force is too large, the plate is prone to deformation.
