Abstract
A method of making a heat exchanger core (,) having a stack of fins (,) having collared holes through which tubes (,) are laced. An overlying fin is supported on an underlying fin by collars (,) around the holes in one of the fins. Leading lengthwise end portions (,) of the tubes are corrugated and each tube is laced, via its leading lengthwise end portion, through a respective set of aligned holes in the fins. Then the tubes are mechanically staked to at least some of the fins in the stack by expanding the cross sections of the corrugated leading lengthwise end portions of the tubes against the collared holes in those fins through which the corrugated leading end portions pass (FIGS.,).
