Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to the mounting direction of a pipe for fixing a hot water supply pipe or the like to a heat absorption/dissipation panel of, for example, a high radiant heating device.

(Prior art) Conventionally, as a means of fixing a pipe to a groove formed on a mounting plate, solder is usually filled between the groove and the pipe, and then the mounting surface between the mounting plate and the pipe is heated from outside with a heater, etc. It was heated and welded using a heating means.

(Problem to be Solved by the Invention) However, when the thermal conductivity of the mounting plate and the pipe are different, for example, when the thermal conductivity of the pipe is small, the heat conductivity of the pipe is poor, and the gap between the mounting groove and the pipe is This tends to cause gaps between the parts, which not only reduces heat conduction, but also makes it difficult to securely fix the two parts using external welding means, resulting in a reduction in the efficiency of the installation process.

The present invention was developed to solve the above-mentioned problems, and its purpose is to quickly connect the outer circumferential surface of the pipe and the inner circumferential surface of the groove when installing the pipe in the mounting groove. An object of the present invention is to provide a method for installing pipes that allows brazing.

(Means for Solving the Problem) In order to achieve the above object, the present invention forms a mounting groove with a substantially circular cross section in a heat absorption/dissipation panel plate,
A circular pipe with a lower thermal conductivity than the panel board is attached to this mounting groove, and a welding agent is filled between the mounting groove and the pipe, and then an appropriate heating means is inserted from inside the pipe. This is a pipe mounting method in which the inner peripheral surface of the mounting groove and the outer peripheral surface of the pipe are pressure-welded by heating from inside the pipe.

(Function) Therefore, in the present invention, a pipe having a circular cross section is attached to a mounting groove formed midway in the length direction of the panel board, and a welding agent is filled between the pipe and the mounting groove. Next, when a heating means such as a pipe heater is inserted into this pipe and heated from inside the pipe, the pipe is heated first, and this pipe thermally expands outward and expands into the mounting groove 2 of the panel board 1. Since the inner circumferential surface is heated, the welding agent melts and the outer circumferential surface of the pipe and the inner circumferential surface of the mounting groove are pressure-welded without any gaps, creating surface contact, and the two are securely fixed. Therefore, the heat of the pipe heated with hot water or the like is reliably transmitted to the panel board, and radiant heat is radiated from the panel board, making it possible to provide a heating device with low heat loss when used for floor heating, etc., for example.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

1 and 2 are longitudinal sectional views of a part of the present invention,
FIG. 3 is a partially cutaway perspective view showing an embodiment of the present invention, and 1 in the figure indicates, for example, a panel board for floor heating,
Alternatively, it is a panel board (attached member) of high radiant heat for heat absorption and radiation that is attached to a wall, ceiling, etc., and this panel board 1 is made of copper in this example, and the panel board 1 has a
or two or more mounting grooves 2 are formed.

3 is a pipe with a circular cross section that supplies hot water heated by a heat source such as solar heat, a boiler, or a heater, or water for heat radiation; in this example, the pipe 3 is made of copper; The conductivity is smaller than that of the above-mentioned panel plate 1, and this pipe 3 is installed in the above-mentioned mounting groove 2 as shown in the drawing.

4 is a long rod-shaped pipe heater (heating means) that includes an electric heat source;
can be inserted in the length direction of the pipe 3 and can be heated from inside the pipe 3.

5 is a welding agent such as solder that is filled between the inner circumferential surface of the mounting groove 2 and the mounting surface of the pipe 3.

Next, the operation of the above embodiment will be explained.

When attaching the pipe 3 to the mounting groove 2 of the panel board 1, first apply a welding agent 5 such as solder to the inner peripheral surface of the mounting groove 2, and then attach the pipe 3 to the above-mentioned mounting groove 2.
When the pipe heater 4 is inserted into one open end of the pipe 3 and the inside of the pipe 3 is heated by the heater 4, the pipe 3, which has a lower thermal conductivity than the panel 1, is heated and the pipe 3 is heated. 3 expands in the circumferential direction and further heats the inner circumferential surface of the mounting groove 2 of the panel board 1, so that the pipe 3 is reliably brought into close contact with the inner circumferential surface of the mounting groove 2 via the filled solder 5. Welded in condition.

Further, FIG. 2 shows another example of the present invention, in which the cross-sectional shape of the mounting groove 2 is approximately circular, a necessary gap 6 is provided, and the panel board 1 is heated by the pipe heater 4 or the hot water supply. It expands in the direction of the gap 6 and securely fixes the pipe 3 in a tight state.

Although the pipe heater 4 is used as the heating means, the pipe heater 4 is not limited to this.
Any material that can be inserted from the inside of the pipe 3 and heated from the inside of the pipe 3 may be used.

(Effects of the Invention) Therefore, according to the present invention, first, the pipe is heated and pressed against the mounting surface in a uniformly expanded state, and then the mounting surface and the pipe are welded together using a welding agent. Because they are fixed in a completely intimate state without forming gaps, for example, hot water inside a pipe is efficiently conducted to the panel board, and the heated panel board emits high radiation, which can be used for floor heating, etc. Compared to the conventional method that heats from the outside, it can be firmly and easily fixed without forming a gap between the two, and the work efficiency has also been significantly improved. It is also possible to reliably eliminate noise caused by the action of hot water or the like supplied into the pipe.

Note that the present invention is not limited to floor heating and the like, but can be widely applied to the case where a pipe is attached to a member to be attached, and its practical value is extremely large.
