| abstract | 1,225,442. Heat exchangers. TRANE CO. 24 Oct., 1969 [30 Oct., 1968], No. 52276/69. Heading F4S. A heat exchanger comprises a heat conductive base member 6 from which fins 7 extend to form therewith at least one groove 9 in which is disposed an insert 8 adapted when positioned to provide a gap a between the insert and the adjacent fin surface, the gap being sufficiently small to initiate and sustain nucleate boiling at the fin surface of a liquid flowing over the surface. In one example given where the boiling liquid is trichloromonofluoromethane, the preferred gap a ranges from 0À0005 inch to 0À002 inch. The base member may be of any suitable shape, e.g. flat or tubular, and the fins may be integral therewith or separately attached. For a tubular base member (e.g. Fig. 2) the finned surface may comprise annular grooves or a continuous helical groove. The groove may be of V-section. The insert may be continuous or it may be segmental. It may be metallic of the same or different metal from that of the base member or it may be of a non-metallic material such as polytetrafluorethylene. The insert cross-section may be circular, oval or rectangular and it may extend substantially over the full height or only part of the height of the groove cross-section. |
