Abstract

A holding system (101, 102, 103) for holding at least one pipe, comprising a comb including a bar and parallel teeth perpendicular to the bar. A blocking device (30) consisting essentially of a pin, serves to prevent a pipe passing between two of the teeth from moving away from the bar.The holding system further comprises two supports (40A, 40B), positioned at the ends of the comb, and which hold the comb so as to allow rotation thereof around the axis of the bar.A method for mounting a heat exchanger (100) comprising such a holding system.

First claim

The invention claimed is:

1. An assembly comprising a cylindrical tube and at least one holding system for holding at least one coil, said at least one holding system comprising:
a comb including a bar and a plurality of parallel teeth, perpendicular to the bar,
a blocking device capable of preventing a turn of the coil passing between two of said teeth to move away from the bar,
the blocking device consisting essentially of a pin, wherein the bar is between the blocking device and the cylindrical tube; and
two supports positioned at the ends of the comb, and holding the comb in such a manner that, when the blocking device is removed, rotation of the comb around an axis of the bar is allowed, during which turns of the coil can pass between the teeth; wherein each of the supports is attached to an inner wall of the cylindrical tube for supporting the turns of the coil and remains attached to the inner wall during the rotation of the comb around the axis of the bar, and
wherein the axis of the bar is parallel to an axis of the cylindrical tube.

2. The assembly according to claim 1 , wherein the blocking device is supported on at least two teeth of the bar.

3. The assembly according to claim 1 , wherein the pin comprises a shell of a generally cylindrical shape split along an axis of the shell.

4. The assembly according to claim 1 , wherein the blocking device has at least one coil support notch.

5. The assembly according to claim 1 , wherein at least one tooth of the comb has a hole, and the pin is configured to pass into the hole.

6. The assembly according to claim 1 , wherein a plurality of passages is arranged in the comb, each passage being arranged between two adjacent teeth so that the coil can pass in the passage, and the axes of cylindrical surfaces of the passages are not perpendicular to an axis of the cylindrical tube.

7. The assembly according to claim 1 , wherein at least one passage in the comb between two adjacent teeth has a cylindrical or toroidal shape.

8. The assembly according to claim 1 , wherein the two supports hold the blocking device.

9. The assembly according to claim 1 , wherein the axis of the bar, around which rotation of the comb is allowed when the blocking device is removed, is distinct from an axis of the pin.

10. The assembly according to claim 9 , wherein the pin of the blocking device is configured to prevent the turn of the coil passing between two of said teeth to move away from the bar towards the axis of the cylindrical tube.

11. The assembly according to claim 1 , wherein the pin of the blocking device is configured to prevent the turn of the coil passing between two of said teeth to move away from the bar towards the axis of the cylindrical tube.

12. The assembly according to claim 1 , wherein the comb is configured to rotate around the axis of the bar between a folded position, in which the comb is folded against said wall, to an extended position, in which the teeth are oriented radially inwards towards a central axis of the tube.

13. A heat exchanger, including at least one assembly according to claim 1 .

14. A rocket engine, including at least one heat exchanger according to claim 13 .

15. An industrial production unit including at least one assembly according to claim 1 .

16. A rocket engine, including at least one assembly according to claim 13 .
