The exhaust valve is located between the cold medium inlet valve provided on the cold medium inlet pipe and the plate heat exchanger body. The setting of the exhaust valve can overcome the phenomenon of insufficient plate compression and rubber strip extrusion deformation after the plate heat exchanger is installed.

[0004] However, in the above scheme, no filtering component is provided at the water inlet, which results in the device not having the function of filtering impurities. After the water with impurities enters the device, the impurities accumulated in the device may cause the device to be blocked over time, thereby affecting the normal use of the device.

[0005] In view of this, the utility model proposes a plate heat exchanger with anti-blocking effect. Utility Model Content
