    • The present invention relates to an evaporation heat transfer tube with a hollow cavity, comprising a tube main body and at least one hollow frustum structure. Outer fins are arranged at intervals on the outer surface of the tube main body and inter-fin grooves are formed between two adjacent outer fins. The hollow frustum structure is arranged at the bottom of the inter-fin grooves and surrounded by side walls. The top of the hollow frustum structure is provided with an opening. The side walls extend inwards and upwards from the bottom of the inter-fin grooves and thus the area of the opening is less than the area of the bottom of the hollow frustum structure. The inner surface and the outer surface of the side walls are intersected at the opening to form a flange. Preferably, the flange is a sharp corner and the radius of the curvature is 0 to 0.01 mm. The side walls are formed by at least two surfaces which are connected to each other. The hollow frustum structure is hollow pyramid frustum shaped, hollow volcano shaped or hollow cone frustum shaped. The height Hr and the height H of the inter-fin grooves meet the following relations: Hr/H is greater than or equal to 0.2. The present invention is ingeniously designed and concisely structured and it remarkably enhances the boiling coefficient between the outer surface of the tube and the liquid outside the tube, reinforcing the heat transfer in boiling and it is suitable for large-scale popularization and application.

    • PROBLEM TO BE SOLVED: To provide a flat tube manufacturing method capable of reducing manufacturing cost more than usual.SOLUTION: The method is provided for manufacturing a flat tube 1 having an uneven shape on inner-outer surfaces. The flat tube 1 is provided by separating an uncut intermediate part 4 from a thin plate 2, by molding the whole as the flat tube 1 by closing mutual tip parts of its cut and raised piece 8 together, by cutting and raising a development shape of the flat tube 1 from the thin plate 2 by sandwiching the uncut intermediate part 4, after processing the uneven shape within a range of the development shape of the flat tube 1, by leaving the intermediate part 4 (a midway part) in the width direction in the development shape of the flat tube 1 while being still joined to the thin plate 2, when forming its notch, by forming the notch of the development shape of the flat tube 1 in the metallic thin plate 2.
    • 要解决的问题:提供一种能够比通常降低制造成本的扁平管制造方法。解决方案:该方法用于制造在内外表面上具有不均匀形状的扁平管1。 扁平管1通过将未切割的中间部分4与薄板2分离,通过将其切割和凸起部件8的相互的顶端部分一起切割并提高一起的展开形状 通过将未切割的中间部分4夹在中间部分4(中间部分)的宽度方向上,在平坦管1的展开形状的范围内处理不平坦形状之后,从薄板2夹持扁平管1 在平坦管1的显影形状中,在与薄板2连接的同时,通过在金属薄板2中形成扁平管1的显影形状的凹口来形成其凹口。
