Working principle
The brazed plate heat exchanger consists of a series of embossed concave and convex stainless steel plates; As shown in the figure below, two adjacent plates are rotated 180° to form a channel, and then pure copper or nickel is used as a brazing filler metal in a vacuum brazing furnace to braze a plate heat exchanger made of corrugated stainless steel plates. A channel is formed between the plates, and the distribution of corner holes on the corners makes the two media alternately flow in the channel. A large number of contact points provide good mechanical strength. The contact points and edges are sealed by copper brazing to ensure complete isolation between the two sides of the media and the outside world.

Heat transfer characteristic
1. Compact structure, easy to install
2. Light weight, only equivalent to 20~30% of the shell and tube heat exchanger
3. Durable, can withstand high temperature and pressure
4. Low fouling coefficient, high turbulence reduces the fouling coefficient, thus reducing the number of cleaning
5. High heat transfer efficiency, less water consumption
