Structural principle

The fully welded plate heat exchanger belongs to the inter wall heat exchanger, which is composed of a set of metal plates with herringbone or chocolate block shaped ripples. A flow channel is formed between adjacent plates, and two different temperature media flow in the flow channels on both sides of the same plate. The plates are sealed by welding. Each medium channel is controlled by a split partition to regulate the flow area and length, ensuring a reasonable flow rate and pressure drop of the medium in the heat exchanger.
For detachable fully welded plate heat exchangers, in the event of plate blockage, the surrounding cover plates can be removed for cleaning.

characteristic

Different forms of heat transfer plates have the advantages of high heat transfer efficiency, compact structure, high temperature resistance, good sealing, and safety and reliability. Compared with detachable plate heat exchangers, they can be used under higher pressure and temperature conditions, meeting the needs of gas-Gas heat exchange, gas-Liquid heat exchange, liquid-Different working conditions requirements for liquid heat exchange.

scope of application

Fully welded plate heat exchangers are widely used in various application fields such as power, machinery, metallurgy, petroleum, chemical, textile, food, papermaking, pharmaceuticals, fermentation, and papermaking.
