    • PROBLEM TO BE SOLVED: To manufacture a fin-integrated tube which does not interpose a solder material therein without the need for a large-scaled device and a long period of manufacturing time, at high quality, and obtain an automobile heat exchanger which is inexpensive and high in performance.SOLUTION: A base end of a cylindrical raw material tube 2' is rotatably held to a tube holding part 3, rolling rollers 41 to 43 surrounding an external peripheral face of the tube from three directions are arranged at a tip side at prescribed lead angles, and a rolling roller head 4 is sent to the axial direction. Shapes of crests R of many mountain portions 44 of each of the rolling rollers 41 to 43 are gradually changed in their axis directions so that widths of the crests R gradually become large from one end side toward the another end side of the rolling roller for serving as a gradually changing roller. The rolling rollers 41 to 43 cooperate to process the cylindrical raw material tube 2' in such a manner that a thickness of its outer periphery is deformed in helical protrusion and it is gradually expanded to erect from the tube in a fin shape.
    • 要解决的问题:为了制造在不需要大型装置和长时间的制造时间的情况下以高品质地插入焊料材料的翅片集成管,并且获得便宜的汽车热交换器 并且性能高。解决方案:圆筒原料管2'的基端可旋转地保持在管保持部3上,从三个方向围绕管的外周面的轧辊41〜43配置在前端侧 以规定的引导角度,并且将滚动辊头4沿轴向方向送出。 每个轧辊41至43的多个山形部分44的波峰R的形状在它们的轴线方向上逐渐变化,使得波峰R的宽度从用于轧制的轧辊的一端侧朝向另一端侧逐渐变大 作为逐渐变化的滚筒。 滚轧辊41〜43配合,以使其外周的厚度呈螺旋形突起变形的方式加工圆筒状的原料管2',并且从管状逐渐扩展为直立状态。

    • PROBLEM TO BE SOLVED: To provide a heat transfer tube having high heat exchanging efficiency and further improved in heat transferring performance, and a heat exchanger including the heat transfer tube. SOLUTION: This heat transfer tube 1 includes a main tube 10 having an inner peripheral face 10a and an outer peripheral face 10b, a corrugated groove 20 spirally formed on the outer peripheral face 10b, and a plurality of recessed parts 30 spirally arranged on the outer peripheral face 10b in the direction opposite to the corrugated groove 20 with respect to the axial direction of the main tube 10. Protruding sections 20a corresponding to the corrugated groove 20 and the projecting parts 30a corresponding to the plurality of recessed parts 30 are formed on the inner peripheral face 10a.
