TECHNICAL FIELD OF THE INVENTION
The present invention relates to a fluid branch (header) fixture. More particularly, the present invention relates to an improved fluid branch fixture for branching or merging a floor heating fluid used in buildings such as ordinary houses, apartment houses, commercial buildings or hotels.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, in order to improve the livability of a general house, an apartment house, a commercial building, a hotel, or the like, a floor heating method of heating an indoor space by radiating heat from a floor has been proposed and put into practical use. Conventionally proposed floor heating methods include (a) a method of placing a heat sink on a subsurface or a surface material of a normal floor, and (b) a heat sink under the surface material of a normal floor. (C) A groove is formed in the surface of the thick heat insulating material layer arranged below the normal floor surface, a heat medium tube is buried in the groove, and a thin metal plate and a surface layer are placed thereon. There is a method of sequentially arranging materials and the like.
[0003]
According to the above-mentioned methods (a) and (b), the heat radiating plate having a structure in which a heating element is disposed inside and heat is generated by energizing the heating element is provided as long as the heating element is disposed at a uniform density. There is no temperature difference depending on the location of the floor surface. However, in any of the above (a), (b), and (c), the radiator plate has a structure in which a fluid is passed through a heat medium (or a "fluid", hereinafter sometimes simply referred to as a "fluid") tube and heated. A large temperature difference may occur between the vicinity of the portion where the fluid enters the fluid tube and the vicinity of the portion where the fluid returns after circulating through the fluid tube. In other words, in the case of a radiator plate in which one fluid tube is arranged in a meandering manner on a radiator plate having a large area, a pressure loss occurs according to the length of the fluid tube, and further, the heat medium becomes more distant from the fluid inlet side. Has a drawback in that the temperature of the heat medium decreases and a considerable temperature difference occurs between the inlet side and the return side of the heat medium.
[0004]
In order to improve the above-mentioned drawbacks, the fluid whose temperature and pressure have been adjusted by the fluid circulation device is branched from one main outflow channel (or “passage”) to a plurality of outflow channels in another direction, and a plurality of return channels are returned. A heat medium branch block (header or fluid branch) that merges the flow paths (passages) into one and returns to the main return flow path has been proposed and put into practical use (see Patent Documents 1 and 2). Such a fluid branch is embedded in the end of a heat insulating layer or heat sink. When placing a heat insulating material on a subfloor surface and placing the fluid branch on it, lay a surface covering material (finishing material) such as a thin floor or cushioning material on the surface for the purpose of adjusting the appearance. There are many.
[0005]
In the case where a fluid branch is connected to a plurality of short tubes by connecting a fluid tube to a lower surface of a floor and a surface covering material such as a thin floor or a cushion material is laid on the surface, (1) a fluid branch There is a drawback in that the portion where is disposed is overheated to cause temperature unevenness, and (2) the surface covering material is pushed upward by the fluid branching body, causing unevenness on the floor surface. The disadvantage of the above (1) is that the fluid whose temperature and pressure have been adjusted by the fluid circulating device passes through the fluid branch, and a heat insulating material is provided at a portion in contact with the fluid branch for the purpose of reducing partial overheating. There is a method of sticking. However, the method of attaching the heat insulating material has the disadvantages that the work of applying the heat is complicated, and if the heat insulating material is thin, the partial overheating is not sufficiently alleviated, and if the heat insulating material is thick, the unevenness of the floor surface becomes conspicuous. .
[0006]
The disadvantage of the above (2) is caused by the heat insulating material on the undersurface of the floor on which the fluid branch is placed and the structure of the fluid branch. That is, (a) a heat insulating material is arranged on the lower surface of the floor so as not to dissipate heat from the heat radiating plate below the floor, but a heat insulating material is arranged in a portion where the fluid branch is arranged. Because the underlayer of the floor is exposed or thinned, there must be a step at the boundary between the exposed or thinned portion and the heat insulating material. (B) The plurality of short pipes joined to the fluid branch are joined at right angles to the side wall surface of the fluid branch, and the fluid tube connected thereto is made of a resin having excellent rigidity such as cross-linked polyethylene. It is difficult to deform, and even if the fluid branch is arranged on the exposed portion of the lower surface of the floor, the hard fluid tube floats the fluid branch and does not contact the lower surface of the floor.

And two return channels are combined into one main return channel (bb) (see FIG. 1 described later). A fluid branch having two fluid flow passages and two fluid return flow passages formed on two side surfaces (b and d surfaces) respectively branches one main flow passage into four, The return channel is merged into one main return channel (see FIG. 1 below). It is preferable that the diameters of the main outgoing flow path and the main return flow path be larger than the diameters of the other flow paths. It is preferable that the short pipe to be joined to the quadrangular plate-like body is smaller than the thickness of the plate-like body because it can be easily joined to the side surface of the plate-like body. Such a fluid branch can be prepared as a structure described in JP-A-10-22672, but is not limited to the examples described here.

A heat insulating material such as an aluminum foil or a foam sheet may be arranged on the lower surface of the floor. By fixing the fluid branch body fixing device on the lower surface of the floor with the fixing device, the short pipe connecting the fluid tubes to the lower surface of the floor is pressed against the fluid branch, and the upper surface of the fluid branch is It is possible to prevent contact with the surface of the space for arranging the fluid branch body, and to form a gap between the two without fail. This gap prevents the fluid branch member fixing device from overheating and makes it difficult for partial heat spots on the heat sink to occur. Further, since the fluid branch is firmly fixed by the fluid branch fixing device, the fluid branch is not lifted upward and the floor surface is not uneven.

In FIG. 2, a fluid branch body arrangement space portion 3 having an outer shape of 55 mm × 50 mm × 11 mm has a back surface 1 ′ (fluid branch body arrangement) almost at the center of the fluid branch body fixing tool 1 having a thickness of 12 mm. The wall 3 of the storage space 3 is provided with a thickness of 0.8. Since the planar shape of the fluid branch 2 is rectangular, the planar shape of the space 3 for disposing the fluid branch is also rectangular. The short pipe arranging groove 4 is made deeper in a portion (the peripheral side of the fluid diverging body fixing tool 1) away from the fluid branching body arranging space 3, and is made shallower in a portion closer to the space portion 3.
