Industrial Water Air Conditioner Heat Pump Plate Evaporator Stainless Steel Brazed Heat Exchanger
Product Description
Principle and application of brazed plate heat exchanger
1. Overview of the principle
Brazed plate heat exchanger is an efficient heat exchange
equipment, its core principle is the use of a series of metal
plates composed of the flow channel, so that two or more fluids in
the plate heat exchange. The brazing technology is to fill the
joint gap after melting the brazing metal to achieve a solid
connection between the metals. In plate heat exchangers, the needle
welding technology ensures the tightness and structural strength of
the plates and provides a stable heat exchange environment for the
fluid.
2. Plate structure and characteristics
Plate heat exchangers are composed of a series of corrugated metal
plates superimposed, and a thin and uniform flow channel is formed
between the plates. Its features include compact structure, high
heat transfer efficiency, small footprint, easy weight maintenance
and so on. In addition, the plate heat exchanger also has the
advantages of strong adaptability, easy expansion and flexible
combination, which can meet the heat exchange needs of different
occasions and processes.
3. Brazing process principle
In the process of brazing, the filler metal is melted and filled in
the gap between the plates, and penetrates into the joint gap
through capillary action to form the connection between the metals.
The brazing process requires strict control of parameters such as
brazing temperature, time and graphite force to ensure that the
brazing filler metal is fully melted and a good joint is formed.
The heat exchanger after brazing has high sealing and structural
strength, and can withstand the pressure and temperature changes
generated during the working process.
