Description

[Detailed Description of the Invention] The present invention relates to the structure of a hot water floor heating system installed on the floor of a house or the like.

In recent years, so-called hot water floor heating, which uses hot water pipes buried in the floors of wooden houses, prefabricated houses, etc., and circulates hot water from central heating and solar water heaters, etc., has been used for indoor heating purposes. ing.

Therefore, in the conventional hot water heating system, hot water pipes 4 are attached to a floor heating panel base material 9', which has meandering grooves 10' on the surface of a panel-shaped insulating material, as shown in FIG. A panel body is installed in which a heat dissipation plate 1' is attached to the top surface of the heat dissipation plate 1', and a circular hot water pipe 4' is brought into contact with the back surface of the heat dissipation plate 1'.

However, when transmitting the thermal energy of hot water to the tatami mats, carpets, etc. above, the contact surface between the circular hot water pipe 4' made of metal or synthetic resin and the heat sink 1' becomes a line contact and is further passed through the heat sink 1'. The heat transfer effect deteriorated and the expected heat dissipation was not obtained.

The temperature distribution on the upper surface of the heat sink 1' is the same as that of the hot water pipe 4'.
Although the temperature is partially high near the top surface, the temperature is low in the area where the hot water pipe 4' is not installed, which has the disadvantage that the temperature is not uniform throughout.

This invention was developed in view of the drawbacks of slanted pipes, and hot water pipes with flat upper surfaces are attached in a meandering manner on a heat sink with parallel pipe grooves, and directly contact tatami mats, carpets, etc. To provide an inexpensive hot water type floor heating with good heat dissipation effect by increasing the contact area of the side wall and bottom wall of the hot water pipes with the heat sink and increasing the amount of heat transfer to the heat sink between the hot water pipes. It is intended for this purpose.

Embodiments of the present invention will be described below with reference to FIGS. 2 to 8.

As shown in FIGS. 2 and 3, 1 is a rectangular thin plate made of metal such as aluminum or iron with good heat transfer coefficient, and has a U-shaped straight pipe groove 2 in the longitudinal direction. Form parallel shapes by pressing multiple pieces to the appropriate dimensions on both ends of the plate,
This is a heat sink formed by vertically cutting both ends of a pipe groove 2 to provide an end opening 3 having a U-shaped cross section.

4, as shown in FIG.
A circular water hole 8 with a U-shape at the bottom for hot water to pass through inside.
A long piece made of synthetic resin with a U-shaped cross section and good thermal conductivity that can fit into the pipe groove 2 of the heat sink 1 and has a height equivalent to the internal height of the pipe groove 2 of the heat sink 1. This is a hot water pipe.

As shown in FIGS. 5 and 6, 9 is a heat insulating board made of a closed foam of synthetic resin having an appropriate thickness and a size approximately equal to that of the heat sink 1. The symmetrical position of the straight pipe groove 2 and the adjacent end openings 3 on the back side of the heat sink 1 at the front end of the image are placed alternately on the left end and the right end of the hot water pipe 4.
The depth is such that even if the U-shaped protrusion of the pipe groove 2 of the heat dissipation plate 1 and the hot water pipe curved part 4a are integrally fitted together at the symmetrical position where the pipe groove 2 is curved, it will not touch the bottom. This is a floor heating panel base material in which grooves 10 having a generally U-shaped cross section and having a width appropriately larger than the width of the pipe groove 2 are formed in a continuous meandering shape.

That is, in the heat sink 1, a plurality of straight pipe grooves 2 are provided in parallel at appropriate intervals, and the back surfaces of both ends thereof are cut into a U-shaped cross section to form the end openings 3.
A hot water pipe 4 made of a long synthetic resin with a planar upper surface and a U-shaped lower surface and a water passage hole 8 inside is inserted from the end opening 3 at the back side of the front corner to dissipate heat. While fitting into the pipe groove 2 on the surface of the plate 1, the other parallel pipe is passed through to the other end opening 3' and curved into a semicircle on the back surface of the heat sink 1 to form a hot water pipe curved portion 4a. As shown in FIG. 5, as shown in FIG.
The hot water pipe 4a is fitted flush with the flat surface of the heat sink 1 that is not the pipe groove 2, and as shown in FIG. They are attached alternately on the left and right sides so that the upper planar upper wall portion 7 comes into contact with them.

Then, a floor heating panel base material 9 formed in a continuous meandering manner with a U-shaped cross section is fitted from below to the heat sink 1 to which the hot water pipe 4 is attached, and fixed with an adhesive or the like.

The grooves in the floor heating panel base material 9 have a depth that does not touch the bottom even when the pipe grooves 2 of the heat dissipation plate 1 are fitted, and a width that is appropriately wider than the width of the pipe grooves 2. Groove 2
An air layer heat insulating section is provided between the floor heating panel base material 9 and the floor heating panel base material 9.

Therefore, a plurality of unit type hot water floor heating panels having the above configuration are installed on the floor of the building, and the upper surface is covered with jutan,
When hot water is circulated by directly installing tatami mats, etc. and using a heat source such as central heating to flow into the water passage hole 8 of the hot water pipe 4, the hot water energy is generated by flattening the upper part of the hot water pipe 4 as shown in Fig. 8. It is conducted to the earthen wall 7 which has a shape of 100 mm, and is directly transmitted to the jutan or tatami mat, and also to the both side walls 6 of the hot water pipe
゜6. The hot water energy transmitted to the lower wall part 5 is transmitted to the circumferential side of the pipe groove 2 of the heat sink 1, then to the upper flat part of the heat sink 1, and further transmitted to the carpet or tatami mat. .

In this case, a heat insulating air layer is provided between the outer side and outer bottom of the pipe groove 2 of the heat sink 1 and the floor heating panel base material 9 in a sealed manner, so that the convection of internal air is extremely small. Although some heat energy transfers to the floor heating panel base material, most of the heat is conducted to the flat portion above the circumferential side of the pipe groove 2.

Therefore, the present invention provides a heat dissipation plate having a plurality of grooves for pipes having end ports at both ends, in which the side wall and bottom wall of the hot water pipe are attached to the inner wall of the ridge, and the side and bottom walls of the hot water pipe are located at both ends of the pipe. Hot water pipes are installed in a meandering manner so that the earthen walls of the hot water pipe curves are in close contact with each other on the back side of the heat sink, and the hot water pipe curves on the back side of the heat sink are placed in symmetrical positions to serve as a fitting and air insulation layer. Install the heat sink so that the outer groove wall of the heat sink and the side and bottom walls of the curved portion of the hot water pipe on the back of the heat sink do not come into contact with the groove inner wall of the floor heating panel base material that does not have meandering grooves. By fitting the panel base materials, the following effects are achieved.

(1) By changing the hot water pipe from metal to synthetic resin, a reasonable cross-sectional shape can be obtained at low cost, and the heat dissipation area is much larger than the circular shape of conventional products, so the heat dissipation plate The temperature distribution above became uniform and the heat radiation temperature became high.

Furthermore, since the upper surface of the pipe is flat and strong enough to withstand external forces from above, it can be installed directly under tatami mats, etc., making it fully effective as floor heating. .

(2) There are no grooves in the curved portion of the hot water pipe, and all the grooves are straight, so the press die cost can be reduced.

(3) Even if water leaks in a part of the pipe, most of the pipe is exposed on the heat sink, so it can be easily discovered and repaired easily and inexpensively.
