    摘要： A heat exchange tube is provided and includes a turbulator therein incorporating a tubular center core and a spiral wrap about the core. The turbulator is first inserted within the heat exchange tube with minimum clearance between the spiral wrap and the internal surfaces of the tube and minimum clearance between the spiral wrap and the tubular core. Thereafter, the tubular core is expanded sufficiently to deform those portions of the spiral wrap engaging the core and also those portions of the spiral wrap engaging the inner surfaces of the heat exchange tube.

    摘要： The object of the present invention is to offer a heat transfer tube having a grooved inner surface, wherein the side edges of the board material do not form a waved shape and cracks do not form during tube expansion. In order to achieve this object, the grooved-inner-surface heat transfer tube of the present invention has a metallic tube with an inner circumferential surface, on which are formed a weld portion which extends in an axial direction of this metallic tube, a pair of projecting strip portions formed parallel to and separate from this weld portion, and a plurality of fins formed in an area between these projecting strip portions. The fins are formed with a constant angle with respect to the tube axis, and the ends of these fins are connected with the projecting strip portions. The thickness of the metallic tube within the grooves formed between the fins is made to increase in approaching the weld portion within an area surrounding the weld portion wherein the central angle is within 30.degree..about.90.degree. on both sides from the center of the weld portion.

    摘要： The present invention relates to an inner finned tube particularly suitable for use in a continuous plate-finned heat exchanger. The plate fins are spaced apart along the tube in heat exchange relation therewith. An elongated cylindrical tube is provided with a plurality of integrally formed and radially disposed inner fins projecting toward the axial center line of the tube. Each fin in cross section is formed having a truncated triangular base and a rectangular portion extending toward the axial center line of the tube. The number of equally spaced formed fins is equal to 2.pi./.theta., where .theta. is the angle subtended between the center lines of two adjacent fins and may vary between 0.45 and 0.345 radian. The radial height of each fin may vary between 14 to 20% of the internal diameter of the tube.

    摘要： An evaporator of a refrigerator provided in a cool air passage includes a serpentine heat-exchanging pipe and a heat-exchanging member wound around the pipe. The heat-exchanging member is shaped in a band having two longitudinal edges. One longitudinal edge of the heat-exchanging member is contacted with the circumference of the pipe, and the other longitudinal free edge thereof has a plurality of cut-off portions. Respective axis of each straight portion of pipe are parallel to each other and in the direction of the air flow.
