Abstract (en)

A method of forming a heat exchanger comprising:- providing a plurality of extruded tubes 1 having parallel micro-bores 2 extending therethrough; closing the ends 3 of the micro-bores 2; forming an aperture 4 adjacent each end of each tube 1 normal to the micro-bores 2, piercing the micro-bores; forming a plurality of spacers 15 by forming apertures 12 in a strip 10 of sheet metal and folding the strip 10 about one or more transverse fold lines 13 such that the apertures 12 are aligned to form a continuous flow path; assembling the heat exchanger by locating a spacer 15 between each end region of adjacent tubes 1 to locate the tubes 1 in spaced parallel relationship and bonding the spacers 15 to the tubes 1 such that the aperture 4 formed in each end of each tube is in fluid communication the corresponding aperture in an adjacent tube via the aperture 12 in the spacer 15.
