As a method of wrapping other materials around the main pipe, there is a method disclosed in, for example, Japanese Patent Application Laid-open No. 83061/1983. This method involves the steps of wrapping the fin material tightly around the outer wall of the main pipe in a spiral pattern at intervals, and fixing the main pipe and the fin material at the portions that will become the ends when the wrapped fin material is cut. and a step of cutting the main tube and the fin material at the fixed portion.

The above object is to provide a device for rotationally driving a main pipe, and a device for rotating a main pipe in synchronization with the rotation of the main pipe in order to spirally wind a tube having heat exchange fins on the outer peripheral surface of the main pipe. A tube guide device provided movably in the axial direction of the tube, in which the tube is wound around the main tube, the starting end of the tube is fixed to the main tube, and the tube is assembled into the tube guide device. a first step of winding the tube around the main pipe while applying a force in an anti-wrapping direction to the tube by a frictional force between the outer surface of the tube and the guide roller and a braking force applied to the guide roller while being guided by a roller; After the first step is completed, the tube is fixed to the guide roller by the frictional force and the braking force while the tube is reversed in the anti-winding direction, and in synchronization with the reversal, the tube guide device is rotated to reverse the direction of the tube. This is achieved by comprising a second step of retracting the tube in the winding start direction by an amount commensurate with the amount, and a third step of fixing the terminal end of the tube to the main tube.

In the first step of winding the tube around the main pipe, it is necessary to fix the starting end of the tube to the main pipe and apply a force in the anti-winding direction to the tube. This is applied by the frictional force between the tube and the guide roller (the frictional force is large because the outer surface of the tube is finned) and the braking force generated by the brake provided on the guide roller. Furthermore, when the main tube is reversed in the anti-winding direction in the second step, it is necessary to fix the tube, and this fixing action is generated by the frictional force and braking force. By reversing the main tube, the outer diameter of the tube to be wound increases.The amount of tube required for this increases when the tube guide device is moved back in the winding start direction, and the portion of the tube wound in the first step increases. The final portion is rewound and covered by this rewound portion (thus reducing the number of turns by a slight amount from the number of turns during the first step).
まず、ハンプソン熱交換器の構成につき第１

で、流れに停滞する部分が生じるため）。 The Hampson heat exchanger configured as described above allows the fluid [ ] to flow inside the tube 2 and the fluid [ ] to the outside of the tube through the pipe 5a.
Heat exchange occurs between both fluids. At this time, if the gaps 〓g 1 , g 2 , g 3 are small, the fluid flow resistance becomes large and it becomes difficult to obtain the required flow rate;
If g 2 and g 3 are too large, the flow resistance will decrease and the flow velocity will be high in some parts and slow in others, resulting in a decrease in heat exchange efficiency (since a fixed amount of fluid is passed through, there will be parts where the flow stagnates) For).

The main tube 1 rotates clockwise as shown in FIG. 9, and at the same time the guide roller 2 provided in the tube guide device 20
By moving the tubes 4a in synchronization, a plurality of tubes 2 to be processed are simultaneously wound around the main tube 1.
As shown in the figure, the phenomenon during winding is that when the points of contact between the tube 2 to be processed, the main tube 1, and the guide roller 24a are points Q and P, respectively, a pressing force in the same direction as the rotational moment around point Q is generated. F acts on point P, that is, the guide roller 24a. In addition, since the guide roller 24a is given a braking force against rotation in advance as described above, the workpiece tube 2 is rotated in the anti-winding direction (rightward in the ninth direction).
Winding is started clockwise from point Q while generating a tensile force of μF, and the winding is directly wound around the main pipe 1. Note that point P of the guide roller 24a can be set to point Q by operating the handle 22b of the tube guide device 20.
- By adjusting the distance between points P and changing the pressing force F, an appropriate tensile force μF is obtained.

う量とする。 When the workpiece tube 2 is wrapped around the main pipe 1 by a predetermined amount and the drive device 19 is stopped in this way, the rotation of the main pipe 1 and the movement of the guide roller 11 are simultaneously stopped as shown in FIG. 10A, and D 1 A straight-wound spiral tube 30 having a winding diameter of 1 is manufactured. At this time, the center of rotation of the main tube 1 is O, and the intersection of the tube fixing plate 8 and the spiral tube 30 on the winding start side is E. Next, when the drive device 19 is operated in reverse, the main tube 1 rotates counterclockwise in the reverse direction as shown in FIG. 10B, and in synchronization with this, the feed screw 17
The tube guide device 20 is moved back in the winding start direction (from right to left in FIG. 3).
During winding, the guide roller 24a rotates and moves together with the tube 2 while applying an appropriate amount of braking force, but during unwinding, the spiral tube 2 that is wound around the main tube 1 tries to unwind. Since the force is sufficiently applied, even if the main tube 1 is rotated in the opposite direction (rewinded), the guide roller 24a will not rotate in the opposite direction.
Further, the tube 2 also does not move in the unwinding direction, and only the already wound spiral tube 2 is unwound while the guide roller 24a and the tube 2 maintain their positional relationship. The amount of reversal is given by the reversal angle α° from point E to point E′ around point O, and the winding diameter D 2 of the spiral tube 30 is obtained when the drive device 19 is stopped. In other words, D 2 can be adjusted in any way depending on the amount of reversal, and is the liquid flow path in the Hampson heat exchanger, which is an important factor affecting its performance. 〓g 1 between the outer surface and the outer surface can be easily obtained. Note that the amount of retraction of the tube guide device described above is an amount commensurate with the amount of reversal of the main tube.

ブを巻付ける方法。1 A device for rotationally driving the main pipe 1 and the main pipe 1
A tube guide device is provided to be movable in the axial direction of the main pipe 1 in synchronization with the rotation of the main pipe 1 in order to spirally wind the tube 2 having heat exchange fins on the outer peripheral surface of the main pipe 1. 20, and in the method of wrapping the tube 2 around the main pipe 1, the starting end of the tube 2 is fixed to the main pipe 1, and the tube 2 is guided by a guide roller 24a incorporated in the tube guide device 20. a first step of winding the tube 2 around the main pipe 1 while applying a force in the anti-wrapping direction to the tube 2 by the frictional force between the outer surface of the tube and the guide roller and the braking force applied to the guide roller 24a; After the first step is completed, the tube 2 is fixed to the guide roller 24a by the frictional force and the braking force, while the main tube 1 is reversed in the anti-winding direction, and in synchronization with the reverse rotation, the tube guide device 2 is rotated.
0 in the winding start direction by an amount commensurate with the reversal of the main tube 1, and then a third fixing step of fixing the terminal end of the tube 2 to the main tube 1. A method of wrapping a heat exchange tube around the main pipe.
