所が多く存在するという点で安全上不利となる。 The prior art will be explained using FIG. In FIG. 1, 1 is a body, 2 is a heat exchanger tube, and 3 is a separation shroud that isolates a downcomer portion 4 and a helical coil portion 5 of the heat exchanger tube. High-temperature sodium 6 flows into the body 1 through the nozzle 7, descends through the outer periphery of the heat transfer tube, and flows out through the nozzle 8. Sodium level 9
The upper space of is filled with an inert gas 10. On the other hand, the water 11 descends inside the downcomer 4,
While rising through the helical coil section 5, it exchanges heat with the high-temperature sodium 6, turns into steam 12, and flows out of the system. The number of heat exchanger tubes 2 varies depending on the scale of the heat exchanger, but generally ranges from several hundred to several thousand.
The heat transfer tube 2 is generally supported at certain points to prevent vibrations caused by the fluid flowing inside the tube.
In particular, the downcomer 4 may expand and contract by 20 to 30 mm due to the difference in thermal expansion with the body 1, so the support portion must have a structure that allows the heat transfer tubes to move smoothly. However, at this time, the contact surface between the heat exchanger tube 2 and the support portion 13 will slide due to expansion and contraction of the heat exchanger tube, so it is necessary to provide a support structure that can prevent wear of the heat exchanger tube as much as possible. Conventionally, as shown in FIG. 2, a hole 15 slightly larger than the diameter of the heat transfer tube was provided in the support plate 14, and the heat transfer tube was fitted into the hole 15 to support it. With such a structure, if the heat exchanger tube is deformed by expansion and contraction and tilted at an angle θ, the heat exchanger tube will slide against the corners 16 of the upper and lower surfaces of the support plate 14, promoting wear of the heat exchanger tube. It turns out. As a means to overcome these drawbacks, a structure as shown in FIG. 4, for example, has been proposed. That is, it has a structure in which a piece 17 is welded 18 to a portion that slides on the support plate 14 and has a wall thickness sufficient to withstand wear. This method increases the number of welding steps and is disadvantageous in terms of safety because there are many welding points at the boundary between sodium and water.
本発明の目的は、熱交換器の伝熱管が熱膨張
し、支持板の孔との間を相対移動しても直接伝熱
管が摩耗しないようにし、且つ伝熱管の傾きを許
し、伝熱管に過大な応力を発生しないようにする
ことを容易に達成する。 The purpose of the present invention is to prevent the heat exchanger tubes from directly wearing out even when the heat exchanger tubes of a heat exchanger thermally expand and move relative to the holes in the support plate, and to allow the heat exchanger tubes to tilt. Easily prevent excessive stress from occurring.

である。 The present invention provides a heat exchanger, in particular a heat exchanger in which a heat exchanger tube is passed through a hole provided in a support plate, in order to extend the life of the heat exchanger tube, and the inner surface of the hole has an arc shape. , a vertically divided collar disposed so as to surround a portion of the heat exchanger tube opposing the hole; a vertically divided nut screwed into a tapered screw provided on the collar; and the divided nut. This is a support structure for heat exchanger heat transfer tubes, characterized by comprising a connecting means for integrating the heat exchanger and heat transfer tubes.
以下にこの発明の具体的実施例を第５図、第６

２２を設けておく。 A collar 19 and a nut 20 having a tapered screw at the upper end are attached to the outside of the heat exchanger tube 4. The collar 19 is tightened and fixed to the heat exchanger tube by a nut 20. The surface of the support plate 14 that contacts the collar is rounded as shown in FIG. 5, so that the support portion and the collar are in contact with each other in an arc. Furthermore, as shown in FIG. 6, the nut 20 is divided into two parts, grooves 21 are formed in both parts, and the parts are engaged with each other to be integrated. Similarly to the nut 20, the collar 19 is divided into two parts and grooves are made in both parts. At the tip of each groove, a stopper 22 is provided on the upper or lower end surface so that the two halves do not move relative to each other.

が計られる。 In the heat exchanger tube support structure configured as above, since the heat exchanger tube contacts the support part through the collar, direct wear of the heat exchanger tube can be prevented.
The integrity of the heat exchanger tubes is maintained. Furthermore, by splitting the nut and collar into two parts, it is easier to attach them to the heat exchanger tubes, which simplifies the process and reduces production costs, especially for large heat exchangers with thousands of support parts. can be reduced. In addition, by rounding the surface of the heat exchanger tube support plate that contacts the heat exchanger tubes, it is possible to alleviate the stress acting on the heat exchanger tubes, reduce the amount of wear on the collar part, and improve the health and life of the heat exchanger tubes. It will be done.
