摘要： PURPOSE:To increase the property of safety against earthquake by a method wherein a tube support plate is provided across the straight led sections of a multitude U-shape heat transfer tubes and the outer end of vibration preventing rod, provided between neighboring U-shape sections of heat transfer tubes, is fitted loosely to a connecting member located at the outside of the U-shape sections. CONSTITUTION:The bundle of heat transfer tubes is constituted of the groups of a multitude of U-shape heat transfer tubes 21, arranged in the same plane, having different radii of curvatures of bending and arranged in parallel with spaces between each others. In this shell and tube type heat exchanger, the tube support plate 22 is provided across the straight leg sections of the heat transfer tubes 21 while the vibration preventing rods 23, located at the U-shape section of heat transfer tube 21, are arranged between neighboring heat transfer tube groups. The outer end of the vibration preventing rod is fitted loosely to a connecting member 24 located at the outside of the U-sections of the heat transfer tubes 21 and either one of the rod 23 or the member 24 is fixed to the outer shell of the heat exchanger. As a result, the vibration of whole of the heat transfer tubes in case an excessive vibrating force is effected is restricted, the safety of the heat transfer tubes may be secured and prominent earthquake-proof performance may be obtained.

摘要： PURPOSE:To contrive facilitated assembly and higher rigidity in a plane at the time of an earthquake while preventing abrasion and corrosion of main bodies of heat exchanger tubes even where ribs are projected at an inclination, by a construction wherein tongue parts of support rings fitted to U-shaped parts of heat exchanger tubes are fastened to a support member provided between the U-shaped parts of the tubes in adjacent rows. CONSTITUTION:The support member 12 is provided between the U-shaped parts of the heat exchanger tubes 11 in the adjacent tube rows. The inner end parts of the support members 12 are connected by a connecting member 15 at the center of bend of the U-shaped parts, the outer end parts of the members 12 are connected by a connecting member 14 on the outside of the tube nest, and the tongue parts 16 of the support rings 13 fitted to the U-shaped parts are fastened to the members 12. Accordingly, even where the ribs 11a are projected at an inclination of 45 deg. against the surface of the tube 11, the thing which makes contact with the support ring 13 is not the main body of the tube 11 but the ribs 11a, so that the main body is not abraded or corroded. When assembling, the rings 13 are fitted to the tubes 11, and the inner and outer end parts of the support members 12 are connected, whereby the structure can be easily assembled. In addition, since the rings 13 and the members 12 effectively restrict displacements of the tubes 11 along the same plane, the rigidity in the plane at the time of an earthquake can be enhanced.

摘要： PURPOSE:To facilitate assembly of a heat exchanger while preventing abrasion and corrosion of main bodies of heat exchanger tubes even when fins are projected at an inclination and contrive enhancement of rigidity at the time of an earthquake, by a construction wherein U- shaped parts of heat exchanger tubes are clamped by engaging recessed parts of support members on a tube row basis, and outer end parts of the support members are connected at the outer end of a tube nest. CONSTITUTION:The heat exchanger comprises the support members 12a, 12b which are splittable and are provided at their opposed faces with a plurality of the engaging recessed parts 12a-1, 12b-1 for the heat exchanger tubes 11, whereby the U-shaped parts of the tubes 11 are clamped on a tube row basis, and the outer ends of the members 12 are connected by a connecting member 14 at the outer end of the tube nest. Accordingly, even when ribs 1a are projected at an inclination of 45 deg. against the outer surface of the tube 11, the thing which makes contact with the support member 12 is not the main body of the tube 11 but the ribs 1a, so that the main body is not abraded or corroded. When assemblying, the U-shaped parts of the tubes 11 are fixed by clamping by the splittable support members 12, and the outer end parts of the members 12, whereby the structure can be easily assembled. In addition, since the support members 12 effectively restrict displacements of the plurality of the tubes 11 with different radii of bend at the time of vibrations along the same plane, so that the rigidity in the plane at the time of an earthquake can be enhanced.

摘要： PURPOSE:To contrive protection of heat-transmitting pipes on the occurrence of an earthquake or a difference in thermal expansion, by a construction wherein both end edges of a support plate fitted to U-shaped parts of heat exchanger tubes are supported by inner end parts of support members connected at the center of a U-shaped bend and outer end parts of the support members connected on the outside of a heat exchanger tube nest. CONSTITUTION:Even where ribs 1a in heat exchanger are projected at an angle of 45 deg. against the outer surface of the heat exchanger tube 11, the thing making contact with the support plate 13 is not the main body of the tube 11 but the ribs 1a, so that the main body is not abraded or corroded. When assembling, the support plates 13 are fitted to the tubes 11, the support members 12 are inserted between the support plates 13, and the inner and outer end parts of the members 12 are connected by connecting parts 14, 15, whereby the structure can be easily assembled. Further, since the plates 13 and the members 12 effectively restrict displacements of a plurality of the U-shaped heat exchanger tubes with different radii of bend at the time of vibrations along the same plane, rigidity in the plane at the time of an earthquake is enhanced. In addition, a gap delta is provided between the upper and lower support plates 13, and absorbs the relative displacement of the plates 13 due to a different in thermal expansion, so that irreasonable forces are not exerted on the tubes 11.

摘要： PURPOSE:To braze securely a sleeve to a machined pipe material without stress concentration by inserting and pressing the sleeve material into the recess at the end of said pipe material with a brazing material held in place between both materials, welding and fixing a supporting member having a large coefft. of thermal expansion to the end and putting the assembly into a high temp. atmosphere. CONSTITUTION:A sleeve material 9 is inserted and pressed into the recess 8 of a machined pipe material 1 with a brazing material 10 held in place between both materials. A supporting ring member 11 having a large coefft. of thermal expansion is inserted and pressed to the sleeve end and is fixed by welding 12 at the end of the pipe material. Such pipe material end is put into a high temp. atmosphere and the brazing part 10 is pressed by the thermal expansion of the member 11, by which brazing is accomplished. Stress concentration at the brazed part of the sleeve is obviated by such method and there is no possibility of cracking. Brazing of the sleeve to the outside circumferential end of the pipe is accomplished by the similar technique.
