Japanese Patent Laid-Open No. 11-281070 JP 10-73265 A

  In the above-described conventional heat exchange panel, if a large area is formed for laying on a large floor or the like, it takes time for packing and transportation, and the space efficiency of the storage location is not good. Further, even the heat exchange panel formed integrally with the flooring material is limited to the size of the flooring material, and there is no foldable heat exchange panel formed in a certain area.

  Further, in the heat radiating member disclosed in Patent Document 1, a storage plate is formed by arranging a plurality of long and narrow plate-like bodies, and a fluid tube embedded in a communication state in a groove formed in the plate-like body. The plate-like bodies are connected in the width direction. For this reason, in order to increase the area, a large number of narrow and narrow plates are connected in the width direction, so that a large number of fluid tubes are exposed between the plates that are connected when folded, causing rubbing and twisting. There was a high possibility of breakage. Further, the grooves formed in the plate-like body are complicated in shape because they are formed in a special shape, and thus cost is high. Furthermore, when laying, a plurality of plate-like bodies are fitted to each other while being shifted to one side so that they can be fitted to each other. Therefore, since the excess fluid tube located between the plate-like bodies is fitted into a deep groove on the side wall surface of the plate-like body and is tensioned and fixed with a nail or an adhesive, the laying operation is troublesome.

  Moreover, in the floor heating panel disclosed by patent document 2, since it formed so that arrangement | positioning between joists was possible, the width | variety of the base | substrate was limited. Furthermore, the surface of the first unit body is shifted by a length corresponding to the length of the connection tube fitted and removed by crossing the connection tube portion from the groove of the connection tube where the surface material is not adhered. In addition, the structure is such that the back surface of the next unit is rotated and folded in parallel to the position where it is overlapped, so that at the bent part of the base body, the conductive tubes cross each other and overlap each other, and the conductive tubes are crushed at the overlapping portions. There was a possibility of damage.

A nail driving range 32 having a predetermined width is formed between the peripheral edge of the storage plate 14 and each pair of the heat exchange pipes 24.

  On both sides in the longitudinal direction of the dividing line 26 of the storage plate 14, folding spaces 36 to which the heat equalizing sheet 16 is not attached are formed across the width direction of the storage plate 14 with a constant width. The width of the folding space 36 to which the heat equalizing plate 16 is not attached is a width that is about the diameter from the radius of the arc when the heat exchange pipe 24 is bent at an interval at which the heat exchange pipe 24 can be bent at 180 °. Further, as shown in FIG. 2, a rectangular lid piece 34 is formed on the surface side of the connector 22 at both ends of the main pipes 18 and 20 so as to be openable and closable.

  Next, the folding method of the heat exchange pipe unit accommodation member 10 of this embodiment is demonstrated. First, as shown in FIG. 2, one side of the storage plate 14 is caused to turn one side of the storage plate 14 about the dividing line 26 of the storage plate 14. Then, the heat exchange pipe 24 located in the bending space 36 is pulled out from the heat exchange pipe storage groove 30 and detached. Next, the caused one storage plate 14 is shifted in the same direction along the dividing line 26 of the storage plate 14 by an interval that allows the heat exchange pipe 24 to be bent by 180 °, for example. Subsequently, as shown in FIG. 3A, the one storage plate 14 that has been raised is brought down so as to overlap the other storage plate 14. Then, the storage plate 14 is folded in two with the dividing line 26 as a boundary, and as shown in FIGS. 3B and 4, the end of the storage plate 14 is shifted in the width direction, and each heat exchange pipe 24. As shown in FIG. 3 (a), the heat exchange pipes 24 are alternately positioned so as to be shifted to the side sequentially. At this time, the bent portions of the heat exchange pipes 24 are sandwiched from both sides in a bending space 36 where the soaking sheet 16 is not attached.

  Further, if the foam cushioning material or the like is sandwiched between the storage plates 14 that are overlapped in a folded manner with an interval of about the folding space 36, the curved portion of the heat exchange pipe 24 is released, so that the heat exchange pipe 24 There is no risk of being crushed and damaged.

  On the other hand, when constructing the folded heat exchange pipe unit storage member 10, as shown in FIG. 2, the one located above the folded storage plate 14 is pulled up and deployed. And it lays on the floor which performs floor heating etc., and the soaking | uniform-heating sheet | seat 16 is stuck in the bending space 34 without the soaking | uniform-heating sheet | seat 16. FIG. Subsequently, as shown in FIG. 5, the cover piece 34 is peeled off, and a heat exchange fluid connecting pipe is appropriately connected to the connector 22 provided on the supply side main pipe 18, so that the plurality of heat exchange pipe unit housing members 10 are connected. Are connected and laid. Furthermore, when fixing the heat exchange pipe unit storage member 10 to the floor or the like, nails or the like are driven into the nail driving range 32 and the pipe unit 12 mounted on the heat exchange pipe unit storage member 10 is fixed without being damaged.

  According to the heat exchange pipe unit storage member 10 of this embodiment, one of the storage plates 14 separated by the dividing line 26 of the storage plate 14 is shifted along the dividing line 26 in the same direction in the width direction of the storage plate 14. Thus, the heat exchanging pipe 24 is shifted obliquely so that the storage plate 14 can be folded. Therefore, the storage plate 14 can be folded into a small size and transported to the construction site, and the workability is good. In addition, the overlapping heat exchange pipes 24 are sequentially shifted laterally at the folding line 26 and are positioned in gaps formed between the heat exchange pipes 24 so that the heat exchange pipes 24 overlap. It wo n’t be crushed. For this reason, the heat exchange pipe unit storage member 10 having a large area can be easily and safely folded. Moreover, since the pipe unit 12 is also formed in a general shape, no assembly cost is required.

As a result, when the storage plate 14 is folded, the heat exchange pipe 24 is subjected to twisting and bending stresses in the same direction. However, if this is deployed, the heat exchange pipe 24 will naturally return straight and easily store the heat exchange pipe. It can be accommodated in the groove 30.

  Further, if the folding space 34 is opened and the foam cushioning material or the like is sandwiched between the storage plates 14 stacked in half, the curved portion of the heat exchange pipe 24 is released and is not twisted and crushed.

  The heat exchange pipe unit storage member of the present invention is not limited to the above embodiment. As shown in FIG. 6, the supply side main pipe 18 and the return side main pipe 20 are adjacent to each other, Provided at one end, the heat exchange pipe 24 is connected at both ends between the main pipes 18 and 20, extends in a direction perpendicular to the main pipes 18 and 20, and is folded at the other end of the storage plate 14. The main pipes 18 and 20 may be communicated with each other.

  Further, as shown in FIGS. 7 and 8, the shape of the dividing line 26 may be a gentle zigzag so that the alignment is automatically performed accurately. This makes it easier to work when the storage plate is opened, and is desirable because no shear stress acts on the heat exchange pipe. The shape of the dividing line 26 may be a wavy shape, a sawtooth shape, or other partial unevenness in addition to the zigzag, and it is sufficient if there is a bendable portion that can be positioned.

  In addition, as shown in FIG. 9, a chamfered portion 30 a that widens toward the dividing line 26 may be formed at the end of the dividing line 26 of the heat exchange pipe housing groove 30. Thereby, when the storage plate 14 is opened, the heat exchange pipe 24 is easily fitted into the heat exchange pipe storage groove 30, and no shear force acts on the heat exchange pipe 24 at the end of the heat exchange pipe storage groove 30, The corner of the dividing line 26 is not damaged.

  Further, the heat exchange pipe unit storage member only needs to be formed so that the pipe unit can be stored in the storage plate, and the size and shape can be appropriately set. The positions of the supply side main pipe and the return side main pipe of the pipe unit stored in the storage plate can be set as appropriate. Furthermore, the installation location can be applied to an appropriate location such as a wall, a tatami mat, and a ceiling in addition to the floor.
