This type of brazed plate heat exchanger is mainly used for refrigeration, evaporator, condenser, and oil cooling, steam heating with relatively large flow.
The working principle of brazed plate heat exchanger
The brazed heat exchanger is generally composed of a set of corrugated plates between the front and back frame. The brazed plate heat exchanger plate packs are assembled by numbers of plate, The brazed heat exchanger can be customized according to the specific requirements of the market and application fields. a solder joint is formed at each contact point between the plate and the filler material (brazing material) During the vacuum brazing process, a brazed plate heat exchanger composed of two different channels or circuits can be manufactured using this design method,. The laser plate is used to seal the gap between the baffle plate and the first and last channel plates. The number of baffles depends on the type, size and pressure level. Some are equipped with a sealing ring to seal the gap between the channel plate and the baffle plate. Some sealing rings are integrated with the baffle plate and the first or last channel plate.

Characteristics of brazed plate heat exchanger:
1. Compact structure, easy installation, high heat transfer coefficient, low liquid stagnation, and thin plate (0.4mm).
2. Light weight, only equivalent to 20%-30% of the shell-and-tube heat exchanger.
3. The water consumption is small and the heat exchange efficiency of the brazed plate heat exchanger is high, so that it only needs 1/3 of the cooling water flow of the shell-and-tube heat exchanger under the same cooling condition.
4. It is durable, can withstand high temperature (200 degrees) and high pressure (45bar), eliminates corrosion problems, and eliminates rubber gaskets.
5. The fouling coefficient is low, and the high flow rate reduces the fouling coefficient, thereby reducing the number of cleanings.
6. High quality, many years of operating experience in the field of heat transfer and excellent computer-aided design make the plate heat exchanger have the highest level of the domestic industry.
