Abstract： |
A method for preparing microchannel and parallel flow exchanger for transcritical CO2 circulation includes extrusion - moulding collector tube in multi-tube structure and heat exchanging flat tube separately to let one side of multi-tube collector tube be planar structure, making parallel slots for heat exchanging flat tubes on planar side of multi-tube collector tube, using weld flux to cover the part of the flat tube to be welded and applying vacuum one - body brass soldering for finishing . |
