Description

[Detailed description of the invention] This invention relates to a floor heating device that uses heat pipes.

2. Description of the Related Art Conventionally, floor heating systems in which heat pipes are placed under the floor are already known.

The purpose of this invention is to provide such a floor heating system that the connection between the heat pipe and the hot water pipe for heating is easy, so it is easy to manufacture, and it is very compact so that it does not take up much space. The purpose is to provide a structure in which the heat transfer effect by the heat pipe is extremely smooth and indoor heating can be performed more effectively than under the floor.

This invention will be explained below based on embodiments shown in the drawings.

In the drawing, 1 is a room of the building, 2 is the floor of the building, and 3 is the left and right side walls.

Reference numeral 4 denotes a floor heating device according to this invention, which is installed under the floor 2.

In this floor heating device 4, reference numeral 5 denotes five heat pipes arranged in parallel under the floor 2, and each heat pipe 5
Both ends of the pipe 5 are closed, a working fluid is sealed therein, and a wick (not shown) is provided to promote movement of the working fluid along the inner wall of the pipe 5 .

At the same end of each of these heat pipes 5, a heat absorbing hanging portion 5a is formed.

Reference numeral 6 denotes a band-shaped heat sink that is fitted over the horizontal heat sink portion 5b of each heat pipe 5 excluding the hanging portion 5a.
A fitting groove 7 with a circular cross section that opens upward is provided in the center of the width of the heat pipe 5, and the heat dissipating portion 5b of the heat pipe 5 is fitted into this groove 7 by so-called click-fitting. A heat dissipation plate 6 is fitted over substantially the entire heat dissipation portion 5b of the heat pipe 5.

The heat absorbing hanging part 5a of the heat pipe 5 passes from the right edge of the floor 2 through a hole 15 made in the inner surface of the right side wall 3
These hanging portions 5a are provided with a large number of parallel annular heat-absorbing fins 8.

Reference numeral 9 denotes a hot water pipe for heat pipe heating disposed within this right side wall 3, and five short branch pipes 10 are provided in an upright manner at a predetermined distance from each other at the upper part of this hot water pipe for heating 9. It is being

A heat pipe 5 is connected to each of these branch pipes 10.
The heat absorbing hanging part 5a is inserted from above, and each branch pipe 10
The upper end of is sealed with a cap nut 11 equipped with a seal.

Reference numeral 12 denotes a heat insulating material provided on the upper surface of the concrete base 13 below the floor 2, and the floor heating device 4 is placed on the upper surface of this heat insulating material 12.

14 is a carpet laid on the floor 2 in the room 1.

In the heating device 4, when hot water is passed through the heating hot water pipe 9, the endothermic hanging portions 5a of the heat pipes 5 are heated in the branch pipes 10 thereof.

As a result, the working fluid sealed in the heat pipe 5 absorbs heat in the hanging part 5a and is evaporated, and this vapor is transferred to the heat radiation part 5b of the heat pipe 5 located under the floor.
, where it radiates heat and condenses.

The heat is smoothly transferred from the tube wall of the heat pipe 5 to the heat sink 6, and is effectively released to the underfloor.
This makes the inside of the room 1 warmer than the floor 2.

Note that the condensed working fluid passes through the wick and moves to the heat absorbing hanging portion 5a, where it is heated again.

Here, since the heat-absorbing hanging portion 5a is in a hanging shape, the working fluid does not accumulate therein, so that the heat transfer action by the working fluid is performed very smoothly.

In addition, when the heat pipe 5 is arranged almost horizontally under the floor as in the embodiment, it is preferable to use the heat pipe 5 with a built-in wick. If the heat pipe is placed under the floor at a slight incline, a so-called gravity heat pipe without a built-in wick may be used.

Further, although the heat sink plate 6 and the heat pipe 5 are connected by clipping, the size of the heat sink plate 6 and the means for connecting the heat sink plate 6 are of course arbitrary.

As mentioned above, in the floor space device according to this invention, the heat absorbing hanging parts 5a are formed at the ends of the same side of the plurality of heat pipes 5 arranged under the floor, and these hanging parts 5a are respectively inserted into the rising branch pipes 10 of the heating hot water pipe 9, and a bag nut 11 equipped with a gasket is fitted onto a portion near the upper end of each heat absorbing drooping part 5a, so that the upper end of the branch pipe 10 is connected to the bag. Since it is sealed by the nut 11, the heat pipe 5 and the heating hot water pipe 9 can be connected very easily and in a sealed state, and therefore the device is easy to manufacture.

Furthermore, since the heat absorbing hanging portion 5a is inserted into the branch pipe 10, the heat absorbing portion of the heat pipe 5 is long, and therefore the amount of heat absorbed is large, and the diameter of the heating hot water pipe 9 can be small.

The heating hot water pipe 9, the branch pipe 10, and the heat
The heat-absorbing hanging parts 5a of the pipes 5 are arranged, as it were, in a plane, so that they can be accommodated, for example, in the side wall 3 and are therefore very compact and space-saving.

Furthermore, the heat absorbing hanging portions 5a of the heat pipes 5 are inserted into branch pipes 10 provided at predetermined intervals in the long heating hot water pipe 9, so even if the floor area is large, the heat pipes can The size and shape of the devices 5 only need to be the same, and therefore the device is very easy to manufacture.

In addition, the heat dissipation portion 5 excluding the hanging portion 5a of the pipe 5
Since the heat dissipation plate 6 having the longitudinal fitting groove 7 on b is fitted over substantially the entire heat dissipation portion 5b,
The heat dissipation part 5b and the heat dissipation plate 6 are in so-called surface contact, which has good heat conductivity, and the contact area is large, so the heat dissipation efficiency is excellent, and the heating in the room 1 is much more effective than under the floor. can be done.
