摘要： An improved tool assembly for enhancing the surface of a heat transfer tube is provided. The tool assembly includes rods having cutting tips and positioned in rod guides which are slidably positioned in shafts provided in a tool holder. In an equilibrium state, the cutting tips do not extend from the tool holder. When a force is applied to the rod guides, the rod guides move in a first direction along the shafts in the tool holder, resulting in exposure of the cutting tips which enhance the tube surface. When the force is removed from the rod guides, the rod guides move along the shafts in a direction opposite the first direction to retract the cutting tips within the tool holder. In this way, the cutting tips are protected when not in use.

摘要： A method of forming a plurality of protrusions on the inner surface of a tube to reduce tube side resistance and improve overall heat transfer performance. The method includes cutting through ridges on the inner surface of the tube to create ridge layers and lifting the ridge layers to form the protrusions. In this way, the protrusions are formed without removal of metal from the inner surface of the tube, thereby eliminating debris which can damage the equipment in which the tubes are used.

摘要： An improved heat transfer tube and a method of formation thereof. The inner surface of the tube is enhanced with a plurality of protrusions that reduce tube side resistance and improve overall heat transfer performance. The protrusions create additional paths for fluid flow within the tube and thereby enhance turbulence of heat transfer mediums flowing within the tube. This increases fluid mixing to reduce the boundary layer build-up of the fluid medium close to the inner surface of the tube, such build-up increasing the resistance and thereby impeding heat transfer. The protrusions also provide extra surface area for additional heat exchange. The method of this invention includes using a tool, which can easily be added to existing manufacturing equipment, having a cutting edge to cut through ridges on the inner surface of the tube to create ridge layers and a lifting edge to lift the ridge layers to form the protrusions. In this way, the protrusions are formed without removal of metal from the inner surface of the tube, thereby eliminating debris which can damage the equipment in which the tubes are used. The protrusions on the inner surface of the tube can be formed in the same or a different operation as formation of the ridges.

摘要翻译： 一种改进的传热管及其形成方法。 管的内表面被增强了多个突起，这些突起减小了管侧电阻并提高了整体传热性能。 突起为管内的流体流动创造额外的路径，从而增强了在管内流动的传热介质的紊流。 这增加了流体混合以减少靠近管内表面的流体介质的边界层积聚，这种积聚增加了阻力，从而阻碍了热传递。 突起还提供额外的表面积用于额外的热交换。 本发明的方法包括使用可以容易地添加到现有制造设备中的工具，其具有切割边缘以切割管的内表面上的脊以产生脊层和提升边缘以提升脊层以形成 突起。 以这种方式，不会从管的内表面移除金属而形成突起，从而消除可能损坏使用管的设备的碎屑。 管的内表面上的突起可以以与脊的形成相同或不同的操作形成。
