The present invention relates to a heating apparatus using a capillary phenomenon heat pipe, and more particularly, to a pipe having a dense and thin metal mesh on the inner wall, digging a fine groove or digging a fine groove, and then attaching a dense and thin metal mesh to the pipe. When the working liquid is injected and the pipe is sealed with a vacuum, the working liquid is distributed evenly on the inner wall of the pipe by the capillary phenomenon, and when one end of the pipe is heated by an external heat source, the gas generated by the evaporation of the working liquid in the heated part is not heated. Known heat pipes that move to unseen areas, transfer latent heat of evaporation around the pipes to cause condensation, and condensed liquids continue to transport by condensing the capillary phenomenon and returning to the heating zone and evaporating again. Features of large latent heat transport, light weight and simple structure, rapid gas flow Relates to an excellent thermal conductivity and excellent thermal efficiency, it triggered a uniform temperature distribution thereof, heating the structure to apply the Unlimited property such as size and shape in the heating.

Conventional hot water circulation heating device is a device that is heated by the heat when hot water flows through a copper pipe arranged in a U-shape has the following drawbacks. First, the heating passage is long, so that the temperature of the water for heating is lowered in the latter part of the passage, so that uniform heat transfer is not possible. Second, the heating path is long, which requires a large amount of pipe, which is expensive. Third, the heating passage is long, so a large number of pipes must be connected to each other, so that the pipe connection is increased and the structure of the pipe is complicated, such as a large number of U-shaped bends, and is easily damaged. Fourth, the risk of leakage of the heating pipe is high due to the high possibility of corrosion of the heating pipe by the water for heating, and the strength of the heating pipe is lowered, thereby increasing the risk of rupture of the heating pipe due to water pressure. Fifth, the scale due to water inevitably accumulates on the inner surface of the heating pipe, so that the thermal conductivity of the heating pipe is significantly reduced.

In order to remove the defects of the conventional excellent heating device, the heating using the so-called heat pipe principle has recently been developed and spread, but this is inclined to the closed pipe in which the working liquid is injected, and the area where the working liquid is collected by gravity is external. When heated by a heat source, the working liquid evaporates to produce steam, which transfers the latent heat of evaporation around the pipe, causing condensation, and the condensed liquid then descends by gravity back down the sloped pipe, Condensed liquid is a method of continuous heat transfer by a system that evaporates by a heat source, which is not true bottom pipe heating but thermosyphon heating. The heating system using this method requires the recovery of the working liquid by gravity, and thus has the following drawbacks in maintaining the inclination of the pipe when applied to the floor heating floor. First, there is a difficulty in construction because the slope must be maintained. Second, the slopes increase the thickness of the ondol. Third, the working liquid is required to be higher than a certain amount at the bottom of the inclined pipe, which requires a large amount of working liquid. Fourth, the heat efficiency is significantly low because the heating is possible only in the downward direction of the site where the working liquid is accumulated. Fifth, there is a limit in the length of the heat dissipation part pipe, so large heating requires multiple heating tubes, thus increasing the installation cost.

The purpose of the present invention is to attach a dense and thin metal mesh to the inner wall, to dig a fine groove or to dig a fine groove, and then to seal the working liquid in a pipe to which the dense and thin metal mesh is attached. The heating of the tube provides a heating device in which heat is immediately transferred and radiated into the heat pipe by the principle of the heat pipe as described above.

The present invention has been made to solve the problems of the hot water circulation heating device and the thermosyphon heating device has the following features. First, since water does not flow in the heat pipe, there is no risk of corrosion, breakage, or leakage of the heat pipe, and there is no harmful effect such as heat conduction deterioration or rupture due to scale accumulation in the heat pipe. Second, since the bending, seam, and inclination of the heat pipe are unnecessary, the structure and the construction are simple, the cost is low, and there is no risk of breakage or leakage of the heat pipe. Third, there is no temperature difference between floors even when applied to large buildings such as apartments due to rapid thermal conductivity. Fourth, water does not flow in the heat pipe, so the irrigation water is remarkably small, and thus the capacity of the boiler is remarkably small, so water has a large energy saving effect. Fifth, since the structure is simple and there is no limit of scale, the floor can be constructed in any shape of vertical, horizontal, inclined, linear, and circular regardless of the size and shape of the room. Can be used. In other words, there is no limit on the use and scale, so it can be easily applied to heating of a large space such as a gym. Sixth, when applied to the ondol it is not necessary to maintain the slope of the heat pipe, the construction is easy and the thickness of the ondol becomes thin. Seventh, the working liquid does not have to be accumulated in the heat pipe, but is enough to be buried on the inner wall, so the amount of working liquid is small and the cost is low. Eighth, the working fluid does not have to be accumulated by gravity, but is distributed evenly on the inner wall of the pipe, so that the front surface can be heated anywhere on the top and bottom sides of the heat pipe, resulting in maximum thermal efficiency. Ninth, even heat dissipation is possible regardless of the length of the heat pipe, so in principle, one heating tube is sufficient and thus the cost is low.

(2) Radiate outward. In this way, the working liquid condensed on the inner wall of the heat pipe while transferring and radiating latent heat moves to one end 2a of the heat pipe 2 buried in the heating tube 1 again by capillary action (X-ray display of FIG. 3). Arrow direction of (4)) In addition, this is evaporated and moved while being heated by the hot water of the heating tube 1 to continuously transmit and radiate latent heat, so that continuous heat transportation is achieved for heating purposes.
