Butt-welding by multi-core vaccum electron beam

The Printed Circuit Heat Exchanger(PCHE) is a micro-channel heat exchanger with high heat transfer efficiencyand compact structure.Photochemicaletching is used to forma flow channel on the sheet, and the stacking of sheet barsand diffusion welding isused to form the heat exchangercore. If necessary, multi-cores are butt-welded, and finallythe cores are welded to channel boxes and connecting pipesto form a complete heat exchanger.

Main Feature

• High pressure resistance:

• Strong pressure resistance up to the maximum 95MPa.

• Operating temperature:-270℃～900℃.

• High density of transfer area: The density of transfer area for PCHE is over three times that of common heat exchanger.

• Compact structure:In case of the same thermal load and pressure drop,the volume of PCHE is only1/6-1/4of traditional shell-and-tube heat exchanger.

• Multimedia heat exchange:Concurrent multimedia heat exchange saves space and greatly enhances quality.

• High reliability:The heat exchange unit is made up of sole parent material without washers andwelding,which can effectively reduce leakage and vibration losses.
