にして解決している。Here, the peripheral portion of the tube plate 4 is crimped to the channel and bottom surface 28 via the gasket 10 to maintain airtightness within the main body Tsukioka 1 (the internal plane of the stepped portion of the channel body 2 is referred to as the channel 8 bottom surface 2a). ). Details of a conventional example of the crimp structure are shown in FIGS. 2 and 3. The one in Figure 2 has the tube plate inside the channel arm 2, and then the tube plate retaining ring 8.
, and then insert the support ring 9 divided into several pieces into the annular groove 2b cut into the inner circumference of the channel 8. A bolt is screwed through the tube sheet retaining ring 8, which presses the green portion of the tube sheet 4 onto the channel fundus surface 2a, and the reaction force of the press is received by the support ring 9. Also the third
In the figure, a stud 7 is erected on the bottom surface 2a of the channel 8, and thereby the tube plate 4 is crimped onto the bottom surface 2a of the channel body. The structure shown in FIG. 2 has the following drawbacks. Here, the enclosure 6 surrounds the fluid inlet group of the U-tube 5 and separates it from the fluid outlet, but it does not fit inside the tube plate retaining ring 8, and it does not block the inner diameter of the ring 8. The diameter of the channel 2 must be increased.Also, a bending moment is applied to the ring 8 due to the difference in the points of action of the bolt 7 and the support ring 9 relative to the ring 8.For this reason, the ring 8 is subjected to shearing force. Due to this bending moment, the ring 6 has to be made thicker, which increases the axial length of the channel body.Also, the connecting tube 6' connecting the enclosure 6 and the fluid inlet of the channel body 2 has to be made thicker. In the case of Fig. 3, the enclosure 6 is placed outside the pitch circle of the stud 7, and the mounting structure is such that the collar attached to it is held together with the tube plate 4 by the nut of the stud 7. Since the ring 8 is not provided, the drawbacks of the one shown in Fig. 2 are greatly improved.However, when dealing with corrosive fluids, the bottom surface 2a of the channel body
Corrosion may occur in the bolt holes 2c, making it impossible to tighten the tube plate 4 and making the main body unusable. Also tube plate 4
If the stud 7 is made of stainless steel and the channel body 2 is made of carbon steel, the stud 7 may be bent due to the difference in thermal tension in the diametrical direction between the two, and the extra shearing force may cause the stud 7 to break. The present invention solves these drawbacks of the conventional devices as shown in FIG.
チャンネル胴２には管板押えスタツド７がたてこまれた
管板押えリング８、チャンネル官同内周に削りこまれた
環状溝に収められた支えリング９、管板４をこの順序で
入れる。A tube plate holding ring 8 having a tube plate holding stud 7 erected therein, a support ring 9 housed in an annular groove cut into the inner periphery of the channel body, and a tube plate 4 are inserted in this order into the channel body 2.

支えリングの割り方を示す。The tube plate holding ring 8 is provided with a fitting 8a into which the inner periphery of the support ring fits. The inner circumferential surface of the support ring 9 and the notch 8a are made to form a hard cylindrical surface fit. This makes it possible to prevent a bending moment from occurring in the tube plate holder 8 due to the vertical attachment of the stud nut 7. Also, as shown in the figure, if the inner circumferential corner of the support ring 9 is wedge-shaped and it is placed against the corner of the notch 8a, the distance between the point of action of the stud nut 7 on the ring 8 and the point of action of the support ring 9 is By minimizing the above bending moment, the occurrence of the above bending moment can be more reliably prevented. If the tube plate retaining ring 8,
If the support ring 9 is configured as follows, it can be easily assembled and still be assembled easily. FIG. 7 shows how to split the support ring in this case.

要としている。The ring is divided into three or more pieces, one of which is inserted at the end of the installation process with the cut ends on both ends parallel to each other. These are made by cutting the annular material into the desired shape and then combining them to form the final shape, so that after being attached to the channel body 2, it becomes a strong support member with no gaps at the seams. Further, the shape of the notch 8a of the tube sheet retaining ring 8 is approximately matched to the wedge shape of the inner peripheral corner of the support ring 9, and the fitting between the tube sheet retaining ring 8 and the support ring 9 is finished loosely. In this way, it is easy to assemble, and when the ring 8 and tube plate 4 are vertically attached by studding, the support ring 9 is pulled toward the center of the ring, and the tube plate retaining ring 8' is pressed down and fixed. The same effect can be obtained as if it were not mated. In this structure, the enclosure 6 has the structure shown in FIG. 3, thereby preventing an increase in both diameters of the channel 8 and eliminating the need for the link 6' shown in FIG.

することができる。The airtight portion between the channel chest bottom surface 2a and the tube plate 4 is the fourth
In the figure, an annular projection is placed on the bottom surface 2a of the channel arm, and the gasket 10 is sandwiched between this and the tube plate 4, but in FIG. 5, the projection is placed on the tube sheet 4 side, and in FIG. An example of the parts is shown below. In this way, according to the present invention, an economical heat exchanger can be achieved by making the channel arms as small as possible and reducing the number of component parts.
