The brazed plate heat exchanger is a plate heat exchanger made by brazing adjacent stainless steel corrugated plates in a vacuum brazing furnace using pure copper (or nickel) as filler metal. The channel is formed between the plates, the corner hole distribution on the corner makes the two media flow alternately in the channel, the number of contact points provides a good mechanical emphasis, the contact point and the edge are brazed by copper (or nickel), with a compact structure, small volume, light weight, high heat transfer efficiency, the total amount of refrigerant filling is small, a wide range of adaptation, good price performance ratio and other advantages.

Channel characteristics of brazed plate heat exchanger
H channel: High heat transfer coefficient. It is suitable for small flow but strong heat transfer (high specific heat, phase change but large temperature difference), such as refrigeration heat transfer.
M channel: Heat transfer coefficient and resistance between H and L channels.
L channel: low heat transfer coefficient, low resistance. It is suitable for large flow and weak heat transfer (low specific heat difference is small), such as air heat transfer under ambient pressure.

Advantages of brazed plate heat exchanger Compact structure: the use of thin stainless steel plate, high heat transfer coefficient, low retention.
Reliable and stable: the selection of stainless steel 304.316L and solder, weld quality is high, can withstand high temperature and high pressure, high fatigue strength.
Less water consumption: The brazed plate heat exchanger has high heat exchange efficiency, so that it only needs 1/3 of the cooling water flow of the shell and tube heat exchanger under the same cooling condition.
Light weight: only 20% to 30% of shell and tube type, reducing transportation and installation costs.
Low fouling coefficient: High turbulence reduces the fouling coefficient, thus reducing the number of cleanings.

Additional accessories: According to the needs of users, we can provide flexible interface design, temperature sensor device, fixing bolts, fixing supports, flanges, clamps, insulation layer.
