The primary fluid that has flowed into the inlet header 2 from the tube header 10 of the tube bundle portion 4 located on the inlet header 2 side as shown by the broken line in the figure.
Flows into each of the heat transfer tubes 11, 11..., Passes therethrough and merges on the other outlet header 3 side, and then is discharged from the fluid outlet nozzle 9 to the outside. On the other hand, as shown by the solid line in the figure, the secondary fluid flows into the body 1 from the fluid inlet nozzle 5 formed in the body 1, and then the baffle plates 17, 17,. After flowing in a meandering manner in the body 1, the heat is indirectly exchanged with the primary fluid flowing in the heat transfer tubes 11, 11,..., And then discharged to the outside from the fluid outlet nozzle 6.

る。However, according to the present invention, the tube bundle 4 is manufactured separately from the body 1 and is detachably attached to the body 1. Therefore, even if such a situation occurs, the tube bundle 4 is not attached to the body 1.
, And can be easily cleaned. That is, when the tube bundle 4 is closed in the state as shown in FIG. 1, as shown in FIG. 3, first, after removing one of the lid plates 7, the retainer presser 13 is rotated to remove. The retainer ring 12 pressed against the retainer presser 13
Is removed to make the end portion of the tube bundle portion 4 open, and then the tube bundle portion 4 can be easily removed by pulling the tube bundle portion 4 straight toward the header side.
Cleaning work can be performed. At this time, the tube sheet 1
Are formed to have substantially the same size as the inner diameter of the body 1 and their edges are in contact with the inner peripheral surface of the body 1, so that the tube bundle 4 is pulled out. , The edges of the tube plate 10 and the baffle plates 17, 17... Move so as to rub against the inner surface of the body 1, thereby effectively scraping and removing the deposits attached to the inner surface of the body 1. can do.

グ材の施工作業等も極めて容易に行うことができる。As described above, according to the present invention, the tube bundle provided in the body 1 is manufactured separately from the body, and the inside of the body is detachably formed. Removal operation at the time of blockage can be easily performed. In addition, since the configuration as in the present invention simplifies the configuration of the entire heat exchanger, the weight can be significantly reduced as compared with the conventional heat exchanger having the same capacity.
Since 0 and 10 have a structure completely separated from the body 1 unlike the conventional case, no end moment is applied to the tube sheets 10 and 10, and metal fatigue and the like hardly occur even in long-term use. Further, since the inner surface of the body 1 can be completely exposed, the work of applying a corrosion-resistant lining material such as titanium to the inner wall surface can be performed very easily.

ない。In the present embodiment, the retainer ring 12 for fixing the tube bundle 4 and the retainer retainers 13 for holding the same are provided on both sides of the tube bundle 4, respectively. The presser 13 does not necessarily need to be provided at both ends, but may be provided at either one. In addition, since the tube bundle 4, the retainer ring 12, and the retainer retainer 13 are actually heavy, a handle, a gripping portion, or a body 1 is formed on a surface of the tube bundle 4 to facilitate removal work. In this case, a hanging ear or the like for hanging the tube bundle 4 may be formed. Further, it goes without saying that the flow directions of the primary fluid and the secondary fluid are not limited to the present embodiment.
