となつていた。 In a conventional panel heat exchanger having such a configuration, a large number of hollow panels arranged in parallel are inexcusably integrated by the fluid supply pipe and the discharge pipe. Generally, in this type of panel heat exchanger, the gap between the hollow panels is very narrow, around 20 mm, so if the hollow panels cannot be separated from each other as described above, the gap between the hollow panels Even if scale from the flowing fluid adheres to the surface of the hollow panel, it is almost impossible to clean it off. Therefore, conventional panel-type heat exchangers are used only when the fluid flowing through the gaps between the hollow panels has almost no scale buildup, which greatly limits its applications. was.

The manufacturing cost is extremely high due to the fact that the shaped bodies must be joined by welding. In particular, it is impossible to manually weld the fitting part of both cylindrical bodies over the entire circumference within the extremely narrow space between both adjacent hollow panels as described above, so a special automatic welding method is required. I needed a machine.

排出管内へ合流する。(Function) In the configuration of the present invention as described above, the space around the fluid supply pipe and the discharge pipe is completely isolated from the outside world by each hollow panel and the annular sealing material between each hollow panel. ing. Therefore, the fluid supplied into the fluid supply pipe is divided into each hollow panel from the circulation hole in the pipe peripheral surface via the radial flow path of the reinforcing ring in each hollow panel, and then flows into each hollow panel. The fluid flowing through the flow path joins into the discharge pipe from the radial flow passage of the reinforcing ring located outside the fluid discharge pipe via the communication hole on the pipe peripheral surface.

ることが出来る。 Furthermore, when the hollow panels are tightened in the axial direction of the fluid supply pipe and the discharge pipe to integrate them, even if the annular sealing material between the hollow panels is sufficiently tightened to obtain the desired sealing effect, The reinforcing ring prevents the plates on both sides of each hollow panel from bending inward due to the reaction force of the tightening, thereby ensuring a constant space between the fluid inlet and outlet of each hollow panel. Further, the hollow panel and the annular seal are positioned by the fluid supply pipe and the discharge pipe. Of course, by unfastening each hollow panel,
Each hollow panel and annular seal can be axially extracted from the fluid supply pipe and the discharge pipe and separated from each other.

By removing the hollow panels 1, the annular sealing material 20, and the back-up spring 21 can be pulled out in the axial direction from the tubes 8 and 9.
As a result, each hollow panel 1 can be freely handled independently, so that necessary maintenance work can be easily performed.

る。 In addition, when forming the wide part 7 for positioning the reinforcing ring 11 on the hollow panel 1 as in the above embodiment, the reinforcing ring 11 is attached to the hollow panel 1.
Since the reinforcing ring 11 can be formed wider than the inner width of the flow path 3, it is not only convenient to mold the reinforcing ring 11, but also the reinforcing ring 11 can be formed wider than the inner width of the flow path 3 of the plate 2.
There is no need for welding, making assembly easier.

なくとも良い。 The inner diameter of the reinforcing ring 11 is made appropriately larger than the outer diameter of the fluid supply pipe 8 and the discharge pipe 9, so that a sufficiently large annular space is formed between them. In the case where the hollow panel 1 is positioned with respect to the discharge pipe 9 using the through holes 10 (see FIG. 6) provided in the plates 2 on both sides of the hollow panel 1, the reinforcing ring 11 The inner circumferential annular groove 12 provided in the inner circumferential groove 12 can be omitted. Moreover, even if a wide annular space is not formed between the inner circumferential surface of the reinforcing ring 11 and the outer circumferential surfaces of the fluid supply pipe 8 and the discharge pipe 9, the radial flow passage 13 can be made into a circumferentially long elongated hole. Alternatively, the slit-shaped flow holes 19 provided in the fluid supply pipe 8 and the discharge pipe 9 are made wide in the circumferential direction, and the radial flow passages 13 on the reinforcing ring 11 side are arranged at small intervals in the circumferential direction. If the hollow panel 1 is arranged so that the radial flow passages 13 always face the slit-shaped flow holes 19 when the hollow panel 1 is attached to the fluid supply pipe 8 and the discharge pipe 9, for example, by disposing them closely together, the same as above can be achieved. In addition, the inner circumferential annular groove 12 may not be provided in the reinforcing ring 11.

得る。 However, the inner circumferential annular groove 12 can be simply and easily formed by, for example, a boring process.
It is desirable to allow fluid to flow smoothly from the reinforcing ring 11 to the radial flow passages 13 of the reinforcing ring 11 without providing significant resistance. Furthermore, the presence of the inner circumferential annular groove 12 shortens the radial flow passages 13, so that machining of the flow passages 13 can be easily performed. From this point of view, it is desirable to form the inner circumferential annular groove 12 as deep as possible within the range where the original reinforcing effect can be obtained, as in the reinforcing ring 11a shown in FIG. Additionally, a reinforcing ring 11b shown in FIG.
The inner annular groove 12 can be formed to have any cross-sectional shape that reduces fluid flow resistance, such as a trapezoidal cross-sectional shape that is wider on the inner ring side.

須条件ではない。 As described above, the structure of the reinforcing ring 11 is not particularly limited. Of course, with regard to the molding material, the most preferable one may be selected, such as various metals, plastics, semamides, etc., in light of the type of fluid to be contacted, operating conditions, etc. In addition, the back-up spring 21 fitted onto the annular sealing material 20 compresses all the annular sealing materials 20 by a certain amount when the hollow panels 1 are fastened and integrated, thereby equalizing the gaps between the hollow panels 1. The use of the back-up spring 21 is not an essential condition of the present invention, although it is useful for ensuring the sealing effect of the annular seal member 20.

パネル、環状シール材の位置ぎめができる。(Effects of the Invention) The panel heat exchanger of the present invention, which can be implemented as described above, can be achieved by simply fitting and fastening each hollow panel to a fluid supply pipe and a fluid discharge pipe alternately with an annular sealing material in the pipe axis direction. Easy to assemble. Moreover, when each hollow panel is tightened in the axial direction of the fluid supply pipe and the discharge pipe to be integrated, the reinforcing ring prevents the plates on both sides of each hollow panel from bending inward due to the reaction force of the tightening, Since the spaces of the fluid inflow and outflow portions of each hollow panel can be secured to a constant width, the first fluid can smoothly flow into the hollow panel as expected. Furthermore, due to the presence of the reinforcing ring, a thin plate with the minimum necessary thickness can be used as the plate forming the hollow panel, which can be implemented economically.
I can do it. The hollow panel and annular sealing material can be positioned by the fluid supply pipe and discharge pipe.

なく活用し得る。 Furthermore, it can be easily disassembled simply by unfastening each hollow panel and pulling out each hollow panel and annular sealing material from the fluid supply pipe and discharge pipe in the axial direction. If the scale of the two fluids adheres to the surface of each hollow panel, reducing heat exchange efficiency or unduly increasing the flow resistance of the second fluid, disassemble and separate each hollow panel as described above. As a result, necessary maintenance work such as removing scale from the surface of the hollow panel can be performed extremely easily. Therefore, the panel heat exchanger of the present invention can be used without any problem even under conditions where the second fluid is used where scale is likely to be generated and adhered.

済的である。 In addition, the fluid supply pipe and the fluid discharge pipe are completely isolated from the outside world by each hollow panel and the annular sealing material, which serves as a flow path for the second fluid, and there is no risk of contact with the second fluid. The fluid supply pipe and the fluid discharge pipe need only be made of a material that does not have an adverse effect in relation to the first fluid flowing in these pipes, and the conditions of both the first fluid and the second fluid should be taken into consideration. There is no need to select the material accordingly. For example, if the first fluid is water, hot water, steam, etc., even if the second fluid is strongly acidic, the fluid supply pipe and fluid discharge pipe are made of inexpensive iron-based materials (SS, SUS, etc.).
