摘要： PURPOSE:To increase the heat exchanging rate of a heat transfer wall of boiling type in the wide range of thermal loading, by providing multi-ply layers of tunnel to the surface of a heat transfer wall so that boiling action can be performed effectively. CONSTITUTION:A number of fine tunnels 3 are formed, crossing with channels 2, underneath the surfaces between the channels 2 which are spirally provided on the outer periphery of a heat transfer tube body 1 at large pitches, while on the surface of a tube a number of fine fins 4 are formed at small pitches, crossing with the channels 2. In addition the outer periphery of a heat transfer tube body 1 is wound and coated by thin tapes 5 continuously at intervals 6, and a number of fine tunnels 7 are formed underneath the tapes 5. When liquid cooling medium, which is to be boiled, is flowed along the outer surface of a tube, while a fluid in comparatively high temperature is passed through the inside of a tube, each tunnel 3 and 7 on the heat transfer wall, being formed as mentioned above, function as part of vapor bubbles generated and grown from liquid. The tunnels 3 in the lower layer are effectively acted when thermal loading is especially low, while the tunnels 7 on the upper layer are also effectively acted when the thermal loading is large, so that the heat transfer wall can show high heat transferring performance in wide range of thermal loadings.

CONSTITUTION:Two copper tapes 3 having a thickness of 0.05-0.3mm. and a width on the order of 2-8mm. are wound helically on the outer circumference of the finned pipe 1 with a gap between the turns of the tapes being on the order of 0.2-1.5mm., and are secured partially to the pipe material 1. By this winding of the tapes, a plurality of the tunnels 41, 42 defined by the fins 2 are formed under the tapes 3. The widths W1 and W2 of the adjacent tunnels are different, and the open section 5 is formed between the turns of the tapes 3 so that the open section 5 allows the tunnels 41, 42 to be in communication with the outside. Steam bubbles of a liquid generated in the tunnels 41, 42 would not be released immediately outside but remain inside. The tunnels 41, 42 accumulate the resulting heat to increase the inside temperature intensively and allow the bubbles to grow efficiently. On the other hand, the open section 5 serves as an inflow port of the liquid into the tunnels 41, 42 and makes the boiling active to increase the heat transfer property.

摘要： PURPOSE:To obtain a heat transfer wall wherein boiling can be performed effectively, the heat exchange efficiency is high, the production is easy and the quality is stable, by winding on the fin tip section on the finned surface a tape having a width wider than the pitch of the fins with the gap between the turns of the tape being narrower than the width of the tape. CONSTITUTION:The surface of a pipe material 1 is cut helically to form the fins 2 whose tips are sharply tapered, and the tape is wound around the circumference of thereof helically with a gap between the turns of the tape. Thus, a plurality of tunnels 4 defined by the fins 2 are formed under the tape 3 and an opening section 5 is formed between the turns of the tape 3 and is in communication with the outside. When a high temperature fluid is passed in the pipe 1 with the pipe 1 immersed in a liquid, each tunnel 4 keeps steam bubbles of the liquid generated therein not to be released immediately and allows the bubbles to grow. Further the tunnels 4 accumulate the heat transferred from the pipe wall to elevate the inside temperatue intensively and allow the steam bubbles to be generated and to grow efficiently. The opening section 5 serves as a releasing section for allowing part of the steam bubbles spread in the tunnels 4 to be released outside of the heat transfer pipe and also as an inlet of the liquid into the tunnels 4, so that boiling thereof is made active and the heat transfer efficiency can be increased.

CONSTITUTION:One or several stripes of channel 2 is (are) spirally provided to the outer surface of a heat transfer tube 1 at comparatively large pitches, and a number of fine tunnels 3, extending to the crossing direction with the channels 2, with their both ends being connected to the channels 2, are formed on the underside of the surfaces between these channels 2. On the other hand, a number of fine fins 4 having sharp tips 41, extending to the crossing direction with the channels 2 are formed on the surfaces between the channels 2 at small pitches. In regard to the heat transfer wall being formed in such a manner, when liquid cooling medium which is to be boiled is passed through the outer surface of each of tunnel 3, while a fluid of which temperature is comparatively high is passed through the inside of the tube, the wall acts as part of bubbles generated and grown from liquid, and the fins 4 raises ultra-large heat flux, as the outer surface area of a heat transfer wall is enlarged. In case that condensing cooling medium is circulated through the outside of a tube and cooling water is circulated through the inside of the tube, the liquid condensed by the fins 4 are sucked by the capillarity of tunnels 3 to make the liquid film on the wall surfaces of fins 4 thin, consequently, condensing action can be activated.
