A heat transfer surface comprising a heat conductive base member and a plurality of spaced apart fins extending therefrom, each of said fins being bent over towards the next adjacent fin so as to form therebetween elongated, re-entrant cavities. The gap between the tip of one of said fins and the next adjacent fin is sufficiently small to promote and sustain nucleate boiling of a fluid in contact with said fins and said base member.
