Pure Copper Brazed Air Stainless Ssteel  Cross Flow Heat Exchanger with High Efficiency

Introduction

Air Cross BPHE is a stainless steel cross flow plate heat exchange which is vacuume brazed with pure copper or

nickel based material as the brazing medium.

The top and bottom plates including side A connections are brazed to the plate package. AirCross BPHE is an

extremely compact and efficient conventional CBE. The construction ensures that every plate separates the primary

(hot) and secondary (cold) fluid. This fact, together with the use of high heat conductivity materials, guarantees

high efficiency.

 

Asymmetrical design

AirCross BPHE is unique as the design is ideal for applications with a smaller flow rate at high pressure on the one

side, (Side A), and a larger flow rate at with lower pressure on the other side. (Side B)

The AirCross BPHE offers this optimized asymmetrical design in several ways:

- Different sizes for the connections In and Out

Side A: Round connections

Side B: Totally open with large inlet and outlet surfaces

- Different channel lengths
 

Side A: 260 mm
 

Side B: 110 mm

- Different channel areas and volumes

Due to AirCross BPHE special plate design the volume/channel is much bigger on side B than on side A.

Volume/Side A channel: 0, 05l

Volume/Side B channel: 0.121



The first channel against the top plate is a half gas channel side B. The last channel against the bottom

plate is also a half gas channel, side B.

Application and Media

Air Cross BPHE is designed for applications with a constant and defined gas flow on one side and medium

with higher density on the other side. For such applications Air Cross BPHE offers a thermal efficiency on the

side B, and a compactness which is significantly better than other heat exchanger solutions. The high efficiency

means that AirCross BPHE can heat or cool the side B fluid to a temperature very close to the incoming temperature

of the Side A fluid.

Normally AirCross BPHE is used with a liquid on side A and gas on side B.




Typical media for side A

Ethylene or Propylene glycol

Water

Refrigerants

Oil/ Hydraulic-, thermal-, mineral-, vegetable-

Other for stainless steel non corrosive liquids

Typical media for side B

Air

Flue gas from burning natural gas, biogas, propane, light oil.

Exhaust gas from engines using above fuels

High pressure gas or air

Nitrogen and other not oxidizing media

Hot or humid process gases

Other for stainless steel non corrosive gases

System design  

AirCross BPHE can be installed either as a single module or in a system including more than one Air Cross BPHE.

In the latter case the heat exchanger

modules can be mounted in parallel or serial configuration on side A and Side B.
 


Parallel on side B for minimum pressure drop.  Serial on side A for max velocity and turbulence.



2 in parallel and 3 in series for side B/the low pressure flow.

3 in parallel and 2 in series for side A / the high pressure side
