摘要： PURPOSE: To prevent brazing defect owing to difference in heat capacities or the like and obtain a pipe joint without using any flux by inserting a pipe into the no- flux joined object of a collar plate and a union, and placing fins in contact with the pipe, the subjecting these to furnace brazing.
CONSTITUTION: First, a collar plate 2 and a union 3 are joined by no-flux joining such as friction joining or TIG joining. Thence, a pipe 1 is fitted into the hole of the plate 2 in the state of mechanical contact therewith, and fins 4 are placed in contact with the pipe 1. If the assembly in this state is subjected to furnace brazing, the brazing defect of the plate 2 and the union 3 having a large difference in heat capacities does not occur. The furnace brazing is carried out by using materials clad with brazing filler metal for the pipe 1, the plate 2, and the fins 2.

摘要： PURPOSE:To facilitate brazing and prevent the lack of braze run by mounting a member which increases heat absorption to a member to a smaller surface area per unit weight out of brazing members in vacuum brazing of target articles of high metallic luster. CONSTITUTION:In the case of brazing a pipe 2 of a large surface area per unit weight and a connector 3 of a smaller surface area, the screw part 10 of a heat transfer piece 8 wound spirally with platelike heat absorbing fins 9 on the outer side is tightened and mounted to the screw part 4 of the connector 3. When these are charged into a vacuum of decompression brazing furnace and are subjected to vacuum or decompression brazing operation, the fins 9 absorb the radiation heat from the heater and further the heat is transmitted to the piece 8, so that the temp. of the connector 3 is elevated by way of the screw parts 10, 4. As a result, brazing filler metal infilters into the joining parts between the connector 3 and brazing seat 6 as well as the pipe 2, and the sufficient brazing is accomplished. Upon completion of the brazing, the piece 8 is removed from the connector 3.

摘要： PURPOSE:To facilitate brazing and prevent lack of braze run by increasing the heat absorption of a member of a smaller surface area per unit weight out of brazing members in vacuum brazing for articles consisting of metals of high reflectivity on surfaces. CONSTITUTION:If there is a difference in surface area per unit weight between target parts in the case of performing vacuum brazing of articles consisting of metals of high reflectivity on surfaces such as aluminum and its alloy or stainless steel, blackening treatment which does not hamper vacuum brazing is applied on the surfaces of the parts of a smaller surface area per unit weight and vacuum brazing is accomplished. If the parts are of a stainless steel material, known means such as a chromic acid oxidation method, a sulfide staining method, and acidic blackening oxidation method are used and if the parts are of aluminum, arbitrary means such as an anodic oxidation method are used. Thereby, the uniform brazing temp. is attained in spite of existence of a difference in surface area per unit weight between the target articles.

摘要： PURPOSE:To readily manufacture a heat exchanger for a vehicle having obliquely corrugated fins for absorbing an impact load by alternately applying opposite forces along longitudinal direction to every adjacent straight tube of zigzag tube. CONSTITUTION:A heat exchanger is placed on a jig. When a drive shaft 26 is then driven in a direction of an arrow, connecting rods 21 are moved forwardly, and parallel links pressurize bent tubes. The bent parts of the bent tubes at the parallel link side are urged and inclined at the corners which are not fastened by fastening pins 9 and movable pins 10. The bent parts of the bent tubes at the stopper 13 side are inclined at the corners which are not fastened by fastening pins 8 and movable pins 10. The displacement of the bent parts is controlled by the stopping angle 15 of the stopper 13. Since corrugated fins 3 brazed to the straight tube are thus alternately relatively displaced to each other, they are inclined with respect to the longitudinal direction of the tubes.

摘要： PURPOSE:To make possible zigzag crooked bending by so providing upper bending dies and comb teeth as to be entered from diagonal above or retreat to diagonal above. CONSTITUTION:In the case of performing zigzag bending to form bent parts D-E, the straight pipe portion of D is gripped by upper and lower bending dies 8, 9 and a rotary pedestal 3 and support frame 4 are rotated 180 deg., by which the pressure bending of D-E is accomplished. This causes the finned pipe groups A, B, C having been previously bent to move together with D to the opposite side. By the operation of cylinders 5, 6 the pipe D is retreated toward right upper side to detaches from the finned pipes and, the upper bending die 8 and upper and lower comb teeth 10, 11 retreat and when they finish retreating, the rotary pedestal 3 and support frame 4 rotate 180 deg. in the opposite direction. After this, the straight pipe portion of the pipe E is advanced by the specified length along a mandrel 1 and the pipe E is rotated clockwise at the specified angle about the mandrel 1 and the pipe groups A, B, C, D are turned at the same angle. After this, the molding dies are again formed and the finned pipe E is gripped. The upper bending die 8 and upper comb teeth 10 enter from left diagonal above.

摘要： PURPOSE:To prevent the lack of resins, and to eliminate the defactive bonding, by detecting anomaly in the coating film, and by changing the delivery pressure of resin, at bonding the heat radiation fin wound around the tube using the thermosetting resin. CONSTITUTION:The thermoplastic resin 3 is delivered from the resin pump/resin melting tank 5, and is spread over the outer surface of the tube 1 through the nozzle 8. Hereupon, if the sensor 12 detects the turbulence or anomaly in the shape of the coating film, the delivery pressure of above stated pump 5 or the feeding speed for the tube 1 is changed by the feedback mechanism correspondingly to the anomaly, in order to form the uniform coating film. Besides, the hot air is blown from the fan 14 so as to maintain the molten state of the thermoplastic resin 3 without setting until the heat radiating fin 2 is completely wound spirally around the tube 1.
