摘要： PURPOSE:To simply and effectively assemble heat transfer tubes and netted fins and to improve an assembling operability by connecting by pressure contact connecting flanges of a pair of tube forming members from outside of the many laminated fins. CONSTITUTION:A heat exchanger has many heat transfer tubes 1 arranged in parallel, and many netted fins 2 connected axially in parallel to the tubes 1. In this case, the each tube 1 is made up of a pair of tube forming members 4, 4. The members 4, 4 are formed in split cylindrical states, connecting flanges 4a, 4b extended in a direction perpendicular to an axial center are attached to their open ends, and connected in pressure contact from outside the fins 2. Thus, assembling of the tubes 1 and the fins 2 are simply and effectively conducted. Parts of the fins 2 are retained in the tubes 1 to form fins 5 in the tube.

摘要： PURPOSE:To provide corrugated fins for a heat exchanger of which heat exchanging performance is more superior than that of a fin having only a net part. CONSTITUTION:Corrugated fins for a heat exchanger are formed by net-like members 14 and 44 having alternatively head parts 14a, 44a and bottom parts 14b, 44b, respectively. The heat parts 14a, 44a and the bottom parts 14b, 44b of the net-like members 14, 44 are provided with plate-like parts 12, 42. The plate-like parts 12, 42 are brazed to a tube 1a.

摘要： PROBLEM TO BE SOLVED: To reduce intrusion of heat from a high temperature side to a low temperature side in an axial direction, decrease thermal resistance of a joint part of a thin-walled pipe and a wire netting and enhance temperature efficiency by using as a material for the thin-walled pipe a copper alloy of a specified wt.% of Ni made by alloying copper or a copper alloy with Ni.
SOLUTION: Five thin-walled pipes (a copper alloy containing 5-40 wt.% of Ni) 2 disposed in a tubular member 1 parallelly with the tubular member, wire nettings 3 closely stacked in a space formed between the tubular member 1 and the thin-walled pipes 2 and wire nettings 4 closely stacked in interiors of the thin-walled pipes are provided. The stacked nettings 4 are held by stoppers 5, 7 and the thin-walled pipes 2 and the stacked nettings 3 are held by partition plates 6, 8. Lids 9, 10 for the tubular member 1, an inlet 12 for inside passages of the thin-walled pipes 2, an outlet 14 for inside passages of the thin-walled pipes 2, an inlet 11 for an outside passage of the thin-walled pipes and an outlet 13 for the outside passage of the thin-walled pipes 2 are provided.

摘要： PURPOSE: To form a face structure excellent in the heat transfer performance by pressing a roll having a projection row to the outer periphery from the outer surface of a heat transfer pipe, forming a large number of projection rows in which the side of the projection at the pipe inner side has a curvature, and determining the projection rows in numerical values.
CONSTITUTION: Projections 3 formed in a pipe inner wall surface 10 is formed by a smooth curve in such a manner that the tip end thereof is pressed by a gear-like roll 2 from the outside of the pipe so that the pipe wall material is plastically deformed. For this reason, the heat transfer promotion is carried out by the above projection, so that the pipe is difficult to undergo a fluid force and hence it has a corrosion resistance. Further, by forming the projection row in the range of the height e of the projection is 0.45W0.6mm, the circumferential pitch Z is 3.5W6mm, and further the axial pitch P is within 9mm, it is possible to make maximum the effect of a vertical vortex having an axis in the flow direction and generated in the flow passing the projection. Therefore, the single-phase heat transfer coefficient can be greatly improved.

摘要翻译：目的：通过从传热管的外表面将具有突出排的辊压到外周来形成传热性能优异的面结构，形成多个突起行，其中突起的侧面为管内侧具有曲率，并且以数值确定投影行。构成：在管内壁面10上形成的突出部3以平滑的曲线形成，使其前端由齿轮状的辊2从管的外侧按压，使管壁材料成为塑性变形因此，通过上述突起进行热传递促进，使得管难于经受流体力，因此具有耐腐蚀性。此外，通过在突起的高度e的范围内形成突出列为0.45〜0.6mm，周向间距Z为3.5〜6mm，轴向间距P在9mm以内，可以使效果最大化具有在流动方向上的轴线并且在通过突起的流动中产生的垂直涡流。因此，可以大大提高单相传热系数。
