Brazed Plate Heat Exchanger Gasket plate heat exchanger Gasket PHE Spare Heating Insulation
Brazing the stainless steel plates together eliminates the need for sealing gaskets and thick frame plates. As well as holding the plates together at the contact points. The plate heat exchanger consists of a corrugated metal plates with portholes for the passage the two fluids between heat transfer will take place. Equally distributing flow in the whole plate improving its heat tranfer efficiency eliminating  the fouling accumulation area. The Baode heating insulation for brazed plate heat exchangers is easily assembled and dismantled. The heating insulation provides protection from the heat pack and keeps the climate in the operating room dry and not too hot.

How it works?

The stainless steel plates are brazed together , then no need for gaskets and frames. The contact points to help hold the plates together, also can take high pressure. the brazing material function is sealing the stainless plates package. Baode's brazed heat exchangers are brazed at all contact points, to make sure best heat transfer efficiency and pressure resistance. The advance of Brazed Plate Heat Exchanger is compact size and light weight, also can take high pressure up to 4.5 Mpa. Baode offers a flexible customer-made design to meet customer-specific requirements then to ensure the most cost-efficient solution for customers' heat transfer duties.
Brazed plate heat exchanger Material
The BPHE (Brazed Plate Heat Exchanger) main components are stainless corrugated plates and copper sheet, the stainless steel plates are brazed together by brazing material (Copper or Nickel) in Vacuum furnace. Copper brazed heat exchanger can be used for numerous of applications. However, for food or applications involving aggressive fluids, Nickel brazed units are recommended.
Brazed plate heat exchanger Fluid Flow principle 
T
he basic flow principle in Baode brazed heat exchanger is parallel (except dual system BPHE) and current flow, this design can achieve the most efficient heat transfer performance. Normally the connections are located on one side of the heat exchanger, this design make easier for installation.
Flow principle in brazed plate heat exchanger Evaporator 

In Brazed plate heat exchanger, the two media flow always in opposite directions, it is called current flow. The two phase refrigerant (vapor + liquid) enters the bottom left of the exchanger with a vapor quality depending on the operating condition of the application. Evaporation of the liquid phase takes place inside the channels and some degrees of superheat are always requested.

Flow principle in brazed plate heat exchanger Condenser
Same components as for the evaporator. The hot gas refrigerant enters at top left of the exchanger and starts to condense on the surface of the channels until fully condensed, sub cooling also requested.
Multipass Design brazed plate heat exchanger

The heat exchanger can be designed as a multipass unit according to customers' need: different connections location and type & size. Customer specific designs are available on request.

Dual system brazed heat exchanger design
What is dual system? The dual circuit means two refrigerant flows and one water flow. this design is diagonal flow design. That means the Brazed Plate Heat Exchanger can be connected with two independent refrigerant circuits. This design can make sure each refrigerant circuit is in contact with the entire water flow. The main advantage is that although when only one compressor running still can maximize the water cooling performance.
