Working principle

The brazed plate heat exchanger is composed of a series of stamped and formed concave and convex stainless steel plates; its composition is as shown in the following figure, two adjacent plates are rotated 180° to form a channel, and then pure copper or nickel is used as a brazing material in vacuum brazing. In the furnace, a plate heat exchanger in which stainless steel corrugated sheets are brazed together. Channels are formed between the plates, and the angular holes on the corners allow the two media to alternately flow in the channels. A large number of contact points provide good mechanical strength, and the contact points and edges are sealed by copper brazing to ensure both sides of the medium. Completely isolated from the outside world.

Heat transfer characteristics

1. Compact and easy to install

2. Light weight, only equivalent to 20~30% of shell-and-tube heat exchanger

3. Durable, able to withstand high temperature and high pressure

4. Low fouling coefficient, high turbulence reduces the fouling factor, thus reducing the number of cleanings

5. High heat transfer efficiency and low water consumption
