The coupling 14 is of metal or plastic and has I-section having an elongated rectangular partition wall 15 and four connecting pieces 17, 18, 19 and 20 projecting as a ridge from both edges 16 and 16' extending along the longitudinal direction of the partition wall 15. The partition wall 15 of the coupling 14 is provided with a suitable number of pass-through holes 21 through which thermal medium can be passed. To the connecting pieces 17 and 18 of the coupling 14 are connected the end parts of the wall members 4 and 4' of the heat exchanger element 10, and in turn, to the connecting pieces 19 and 20 are connected the end parts of the wall members 4 and 4' of the heat exchanger element 10', respectively. The connected surfaces are rigidly fixed by a high- frequency welder and hog-jet process to prevent a leakage of the thermal medium during its circulation.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a joint structure of heat exchanger elements used in hot water circulation type floor heating equipment, other heating equipment, etc. It is used by connecting to devices, etc. The heat exchanger element performs heating by passing a heat medium such as hot water sent from a heat medium circulation device or the like through the heat exchanger element and exchanging heat.

As shown in FIGS. 1 and 2, a conventional heat exchanger element includes a planar bag 1, and an inlet/outlet 2.3 is provided in the lower surface of the bag 1 to allow a heat medium to flow therein. bag l no 1
The lower wall surface is formed of topsheets 4, 4' made of rubber or resin that do not allow heat transfer to pass through.On the inside of the topsheets 4゜4', there is an inner sheet made of fabric or the like as required. 5 and 5' are provided, forming a double wall structure. Inner sheet 5.5' and top sheet 4
, 4' are fixed to each other by heat welding or gluing. The bag body 1 is made of a single wavy monofilament 6 undulating upward F, or a wavy monofilament 6 and a straight monofilament perpendicular thereto, so that a predetermined interval is left between the upper and lower walls so that the heat medium can flow inside the bag 1. A spacer 8 such as a corrugated mesh consisting of 7 is provided. 9 is a rug such as a carpet. Usually, a plurality of such heat exchanger elements are connected and used. As shown in FIGS. 3 and 4, each connection of the heat exchanger elements is connected via a tube made of a material such as metal or plastic as shown by the arrow (each heat exchanger element 10° 10').
, 10'l, the outgoing pipe 11 of the circulation system - Output port 3 - Population 2', Outlet 3' - Population 2''
, outlet 3 and return pipe 12 are connected to each other. The heat medium that has exited the return pipe 12 is configured to pass through a storage tank, a heat exchange section, and a pump, return to the outbound pipe 11, and repeat the circulation, although none of these are shown.

However, since the connecting piping for each inlet and outlet of such conventional heat exchanger elements is performed on a part of the floor 13, the piping work is very difficult and inefficient. Moreover, since multiple holes are drilled in the floor surface, the work is complicated and the strength of the floor section is impaired.

This invention was made in view of these circumstances, and by making the joints of each heat exchanger element have a special structure,
The present invention provides a joint structure for heat exchanger elements that reduces work under the floor, is easy to install, and is inexpensive to construct.

This invention provides a heat exchanger that constitutes a space that seals a heat medium by arranging two wall materials that do not allow the heat medium to pass through, with a gap that allows the heat medium to pass between them. The structure of the joint where exchanger elements are joined to each other, and the length of the partition wall between two adjacent heat exchanger elements at the joint is provided with an appropriate number of through holes through which the heat medium can pass. A joint having a summer-shaped cross section with four joint pieces protruding like an eave on both sides from both ends along the horizontal direction is arranged, and the two wall materials of each heat exchanger are connected to the two walls on the same side of the joint. The gist of the present invention is a joint structure for heat exchanger elements, which is characterized in that each heat exchanger element is joined to two joint pieces.

Hereinafter, embodiments thereof will be described in detail with reference to the accompanying drawings.

FIG. 5 is a perspective view showing a joint structure of a heat exchanger element according to the present invention. 6 is a partially cutaway perspective view taken along the line BB' in FIG. 5. FIG.

In FIGS. 5 and 6, the heat exchanger element 10°10
' are connected via a joint 14. The joint 14 is made of a material such as metal or plastic, and includes an elongated rectangular partition wall 15, and four joint pieces 17 that protrude like eaves on both sides from both edges 16, 16' along the length of the partition wall 15. It has a summer cross section with 18, 19 and 20. The partition wall 15 of the joint 14 is provided with an appropriate number of through holes 21 through which a heat medium can pass. Joint piece 1 of joint 14
7 and 18 to which the ends of the wall material 4.4' of the heat exchanger element 10 are joined, on the other hand to the joint pieces 19 and 20 of the coupling 14.
The ends of the wall material 4, 4' of the heat exchanger element 10' are respectively joined to. The joint surface is high frequency elder.

It is firmly welded using a hot jet method to prevent leakage of the heating medium during circulation.

In such a configuration, the heat medium flowing into the heat exchanger element 10 from the outgoing pipe 11 through the inlet 2 flows in the direction shown by the chain arrow in FIG. It flows through the through hole 21 of the joint 14 into the heat exchanger element 10'. Next, it flows within the heat exchanger element 10' as indicated by the chain arrow, reaches the outlet 3, and exits to the return pipe 12. After that, it is circulated according to the normal circulation system. Although FIGS. 5 and 6 show the state in which two heat exchanger elements are connected as an example, the present invention is not limited to this (the number of joints may vary even if there are three or more heat exchanger elements). The bonding structure remains unchanged, only increasing.

In addition, when four heat exchanger elements are connected as shown in Fig. 7, a cross-shaped joint 2 is installed in the center as shown in Fig. 8.
2 can also be used. The joint 22 is the summer type joint 1.
4 intersect in a cross shape and have an integrated shape.

Similar to the joint 14, the cross joint 22 includes a rectangular partition wall 23 having an appropriate number of through holes 21 for passing heat medium from adjacent heat exchanger elements, and both ends of the partition wall 23 along the length direction. 4 that protrudes like an eave on both sides from the edges 24 and 24'
It consists of four structural parts having joint pieces 25, 26, 27 and 28 which are integrated to form a pouvée shape. The 2204 cross joints 23 are joined to the partitions 15 of the four joints 14 having the same structure as described above, respectively, by welding or adhesive. The four heat exchanger elements 29, 30, 31 and 32 are connected via such joints 22, 14 as shown in FIG.

The heat medium flowing into the heat exchanger element 29 from the outgoing pipe 11 via the inlet 2 flows in the direction shown by the chain arrow in FIG. It flows into the exchanger elements 3o and 31, and then passes through the through holes 21 of the cross joint 22 and the joint 14 that constitute the joint with the heat exchanger element 32, and flows into the heat exchanger element 32 through the outlet 3. Then, it exits to the return pipe 12 and is circulated.

It should be noted that the end portion 33 of the heat exchanger element is shown in FIGS. 9 and 1.
As shown in Figure 0, an end sealing material 34 made of a U-shaped W resin molded product is inserted and attached in the direction of the arrow, and welded using high frequency or the like. As a result, the end opening of the heat exchanger element is tightly sealed, and leakage of the heat medium can be prevented. Other closure structures may also be used.

This invention has a joint structure in which a joint through which a heat medium can flow is attached to each joint of the heat exchanger element. Therefore, in any case, there are only two piping points at the entrance and exit, so the work on floor F is significantly reduced. In addition, heat exchanger elements of any size can be produced in a factory, which reduces construction costs.
