Description

[Detailed Description of the Invention] The present invention relates to floor heating using heat pipes.

Heat pipes that consist of a heat pipe and a heating source have been known for some time (Utility Model Application No. 13675/1983), but when these devices are installed on the floor, the working fluid in the heat pipe flows over the slope of the floor. In other words, if the heating source (evaporation part) is installed higher than the condensing part of the heat pipe, heat transfer will be incomplete due to the backflow of the working fluid, reducing the heating effect, and if the heating source is a gas burner, etc. If the heating is done in a vacuum, it has the disadvantage that it causes a dry firing condition due to the bias of the working fluid.

The present invention solves the above-mentioned disadvantages, and will be explained in detail below with reference to the drawings. FIG. 1 is a plan view of an embodiment of a floor heater of the present invention, which uses hot water heating and has a hot water heating source and a heat pipe connected in series. 1 is a heat pipe, 2 is a hot water heating passage, and one end of the heat pipe 1 is in contact with the passage. 2' is a hot water inlet, and 2'' is a hot water outlet.
Connect one side of the floor heating device to the floor surface with heat pipe 1
However, since this angle of inclination is about 1 to 2 degrees, a level 3 is provided to visually check the inclination. This is done via the height adjuster 4 and the like while visually checking the position using the level 3. FIG. 2 is a cross-sectional side view taken along the line AA in FIG. 1. In FIG. 3, a height adjuster 4 is used to set the heating source 2 lower than the heat pipe 1 with respect to the floor surface, and the inclination is checked using a level 3. FIG. 4 shows a window portion of the spirit level 3 showing the moving position of the bubble.
FIG. 5 shows a plan view of another embodiment. FIG. 2 is a plan view showing an embodiment in which a plate-shaped heat pipe 1 is heated with a heating body 7 using a gas burner or the like (not shown).
FIG. 6 is a sectional side view taken along the line BB in FIG. 5, and shows a configuration in which a part of the flat heat pipe 1 is used as a heating body 7 of a gas burner. FIG. 7 shows a window portion of the circular spirit level 3 showing the moving position of the bubble.

Incidentally, a spirit level may be attached directly to the heat pipe, or may be provided on the case body, so that it can be confirmed whether the heat pipe is at a higher position than the heating source.

As described above, according to the present invention, the heat pipe has an inclination, and the inclination angle is necessary to flow the working fluid from the condensing part to the heating part (evaporation part).
Generally, a small angle of 1 to 2 degrees is required, so it is difficult to secure this angle when installing on the floor, especially on a tatami surface. This prevents inconveniences such as non-operation of the hydraulic fluid in the pipe, and has the effect of preventing dry firing.
