移動することはない。Referring to FIG. 7, the sleeve 21 is halved in the axial direction so that it can be easily attached to the connecting portion 11 (or the shaft portion 100) of the U-shaped tube 3.
Stoppers 27 are integrally formed at both ends of the holder to prevent the U-band 23 from being displaced. According to this
After fixing with the U band 23, the sleeve 21 does not move in the axial direction.

7 is provided, so that when the U-shaped tube 3 contracts due to heat contraction, the sleeve 2 moves from the portion fixed by the U band 23.
1 never comes off. Further, since the sleeve 21 is divided into two parts 21a, the sleeve 21
It is easy to attach the U-shaped tube 3 to the U-shaped tube 3.

For example, the sleeve 21 is not limited to the one made of fluororesin as long as it is made of a material having a good slip property. However, those made of resin having excellent moldability are preferable.
Further, in consideration of strength, the frame member 10 can be made of stainless steel.

るものになる。As is apparent from the above description, according to the first aspect of the present invention, a box-shaped frame member fixed to the tank truck is provided, and the box-shaped frame member has a plurality of fins. Book U-tubes in parallel, connect each U-tube with an inlet header and an outlet header, and connect the U-tubes to each other at multiple points on the shaft of each U-tube, including the joints that connect each header to each U-tube. Since it has a structure that is fixed to the frame member with a U band, vibration, shock during transportation,
Alternatively, it can sufficiently withstand thermal contraction when passing the liquefied gas.

防止される。According to the second aspect of the present invention, by interposing the sleeve which is divided in half in the axial direction, each U-shaped tube can be freely contracted through the sleeve even if thermal contraction occurs, so that it is firm. As compared with the case where it is fixed to the U.S.A., the welded part is less likely to crack, and it can withstand thermal contraction sufficiently. Moreover, stoppers are provided at both ends of the sleeve. The engagement of the bands prevents axial movement of the sleeve during heat shrinkage.
