Abstract: PURPOSE:To prevent a deformation as well as a damage of a heat radiation pipe by a method wherein a reinforcing element is arranged along a bent imaginary line of a metallic plate, a heat radiation pipe is arranged in perpendicular to the bent imaginary line at its proper location, raised and bent to form an outer box frame. CONSTITUTION:Four reinforcing parts 3 having an L-shaped section are spaced apart to each other and installed at a central location of a flat steel plate 1a in such a way as its rising portions 3a face outwardly, a heat radiation pipe 21 is arranged at a predetermined position and supported at its specified position with the reinforcing parts 3 or any heat radiating thermal transmitting tape and the like. A raw member 1a is set in a bending type composed of an inner die 6 and an outer die 7, the reinforcing parts 3 are pressed by the inner die 6, the outer dies 7 are moved to cause both sides of the raw element 1a to be raised and bent along the rising side 3a of the reinforcing parts 3 and both outer dies so as to form an outer box frame 1A. At this time, the heat radiating pipe 21 is also bent along the bending die 6a for the heat radiating pipe arranged at a location where both inner dies overlap the reinforcing parts.

Abstract: PURPOSE:To prevent a deformation and a damage as well as a leakage of a heat radiating pipe by a method wherein when an outer box frame is formed, zig-zag parts for accommodating a movement of a heat radiating pipe generated due to a difference of bending curvatures of a flat raw element and the heat radiating pipe are arranged at both side walls of the outer box. CONSTITUTION:A steel plate raw member 1a is formed into a flat plate of a predetermined shape and a heat radiating pipe 21 bent into a predetermined shape is mounted and installed on the raw element 1a. The heat radiating pipe 21 has, at any position of a wall corresponding to a bent side when the outer box frame of the flat plate raw element 1a, any zig-zag part 2a for accommodating a movement of the heat radiating pipe 21 generated due to a difference of bending curvatures of the raw element 1a of U-shaped or L-shaped and the heat radiating pipe 21. An inner die 6 is set in the raw element 1a formed as described above. The inner die 6 has a bending die, a raw element bending die 6a and a heat radiating pipe bending die 6b having different bending curvatures. When the outer box frame 1A is formed, the raw element 1a and the heat radiating pipe 21 are bent simultaneously in a cubic form along a predetermined bending die of the inner die 6. The cubic bending of this heat radiating pipe 21 is bent along the bending die 6b, resulting in that the heat radiating pipe 21 may not be collapsed and not be spaced apart from the outer box frame 1A.

Abstract: PROBLEM TO BE SOLVED: To discharge the air in a space defined by inner and outer boxes stably at the time of filling a foamable thermal insulation material by making a recess in the outer box and air vents for filling the foamable thermal insulation material at the opposite ends of the recess. SOLUTION: A recess 11 is made in an outer box 4 by press and holes 12 are made at the opposite ends thereof so that the air in a space defined by inner and outer boxes 2, 4 is discharged stably at the time of filling a foamable thermal insulation material 3. According to the arrangement, no cavity is generated in the foamed thermal insulation material 3 and the labor conventionally required for bonding a porous soft urethane foams through a paste layer in order to prevent leakage of the foamed thermal insulation material 3 through the air vent along with the air can be saved at the time of filling the foamed thermal insulation material 3. Furthermore, a press pin 13 can be protected against breakage and a steel outer box 4 can be protected against cracking at the time of making the air vent 11 by means of the press pin 13 and a die 14.
