摘要： PURPOSE:To introduce liquid, entered into a tunnel from opening holes of liquid capillary tubes on a rough surface, to facilitate to wet the whole periphery of the tunnel and improve heat transfer by a method wherein the internal wall of the tunnel of heat transfer wall, having the opening holes and the tunnels, is worked so as to be the rough surface. CONSTITUTION:A shallow groove is made on the surface of a circular tube by knurling work in the direction of substantially 45 deg. with respect to the axis of the tube. Then, plow-up work is applied by a tool into substantially orthogonal direction to the axis of the tube to form the row of fins provided with recesses and protuberances. Successively, fine metallic powder is collided against the heat transfer wall of valleys between fins to roughen the wall surface. The fins are laid down by rolling work, brushing work or the like to form the tunnels by connecting neighboring fins. The tips of the fins are provided with the recesses and protuberances, therefore, the recesses form the opening holes after the rolling work or the like and the size of the opening hole may be controlled easily in the process of production.

摘要： PURPOSE:To provide a heat transfer wall for a heat exchanger which is surpassing in both boiling and condensing performances, by making the shape of fins provided to the heat transfer wall in a special design. 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.

摘要： PURPOSE:To provide a heat transfer wall whose quality is stable and that is excellent in heat transfer property, by arranging, on the tips of fins of a finned surface, tapes whose width is wider than the pitch of the fins, and forming notches at the tips of the fins with a prescribed interval between them. CONSTITUTION:The tapes 4 are wound, and a plurality of tunnels 5 are formed under the tapes 4 and are separated by the fins 2. The upper parts of the tunnels 5 are in communication with each other via the notches 3 formed at the tips of the fins 2. Opening sections 6 are formed between the turns of the tapes 4 for allowing the tunnels 5 to be in communication with the outside. When a high temperature fluid is passed into the pipe 1 with the pipe 1 immersed in Fron liquid, since the tunnels 5 are communicated with the outside through the opening sections 6, the bubbles of vapour generated in the tunnels 5 would not immediately goes outside but remain there. Further since the involved heat is accumulated in the tunnels 5, and the internal temperature is raised concentrically, the bubbles of vapor are generated and grown efficiently in the tunnels 5, and the notches 3 that make the tunnels 5 in communication with each other assist the movement, association and growth of the bubbles of the vapor.

摘要： PURPOSE:To improve the heat transfer performance of the wall by a method wherein the hole of the heat transfer wall is provided with a protuberance, protruding into a direction crossing the hole, at the inside thereof to regulate the trafic of fluid passing through the hole. CONSTITUTION:When the pressure of steam bubble 103 becomws higher than the stabilizing condition of gas-liquid interface in a narrow clearance 107, a part of the steam bubble 103 is released to the outside of the heat transfer wall 1 as an air bubble 101. On the other hand, external liquid is supplied from the narrow clearance 107' into a cavity 2 by the pressure fluctuation and capillary force in the cavity 2 associated with the grow and release of the air bubble 101. A liquid film 105 between the steam bubble 103 and the inside of the cavity is very thin, therefore, it is evaporated immediately when it is slightly overheated by the wall of the cavity and supplies steam to the steam buble 103. On the other hand, the supply of external liquid 102 collides once against the protuberance 6 and thereafter is introduced into the cavity 2, therefore, it flows into the cavity 2 in the state of overheated liquid. The liquid, flowing into the cavity 2, is changed in the flow direction thereof by the protuberance 6, therefore, the supply of liquid to the liquid film 105 is effected smoothly and the supplying amount is limited. thus, the high heat transfer rate may be obtained since the stable liquid film is formed in the cavity 2, and especially the heat transfer rate in the area of low overheating of the heat transfer wall may be improved remarkably.

摘要： PURPOSE:To contrive to increase the overall heat transferring efficiency of a boiling type heat transfer tube, by forming channels which function as openings for tunnels provided on the outer surface of a heat transfer tube, as well as to form projections in the tube by a corrugation work in order to increase the heat transferring rate. CONSTITUTION:A heat transfer tube of out of tube boiling type for a heat exchanger is manufactured by treating a corrugation work and forming spiral projections 4 on the inside wall of a heat transfer tube 1, as well as to form spiral channels 3 on the outer surface of a tube, and in addition, by forming a number of fine tunnels 7 of which both ends are opened to the vicinity of the spiral channels 3, which are formed on the outer surface between the above-mentioned channels 3. The tunnels 7 being formed in such a manner function as part of bubbles generated and grown from liquid, when a liquid medium which is to be boiled is passed through the outer side of a tube, while a liquid in comparatively high temperature, which is not accompanied with a phase change in the tube, is passed through the inside of a tube. On the other hand, the projectins 4 being formed on the inside of a tube by corrugation work act so as to increase the heat transferring rate in the tube.

摘要： PURPOSE:To obtain a heat transfer wall whose boiling heat transfer property is improved through tunnels, by forming two layers of a plurality of fine tunnels that are located under each surface between grooves with a large pitch, are extended crossing with the grooves, and are formed integrally with a heat transfer wall and whose both ends are in communication with the grooves. CONSTITUTION:A heat transfer pipe includes a heat transfer main pipe 1 having the helical grooves with a large pitch, and two rows of the plurality of fine tunnels 3, 4 are extended under each suface between the grooves 2 normally to the grooves 2 and are integrated with the main body 1. The inclinations of the rows of the tunnels 3, 4 may or may not the same to the grooves 2. The numbers of the tunnels in the rows may or may not the same. The opposite ends of the tunnels 3, 4 are open adjacent to the grooves 2, and are in communication with the outside via each of gaps 5. The inside of the pipe main body 1 may be smooth, but in this aembodiment, the parts corresponding to the grooves are projected helically. Accordingly, if the fluid in the pipe flows slowly, turbulence effect occurs, and the heat transfer efficiency in the pipe can be improved.
