Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a geothermal heat retention device, and its main purpose is to effectively transfer geothermal heat transported by a heat pipe to a heat receiving body.

Recently, snow melting and anti-freezing systems using heat pipes have been attracting attention, but there is no effective measure for the heat transfer part between the heat pipe and the heat receiving body, and the defect is that the geothermal energy that has been transported through the trouble cannot be sufficiently transferred to the heat receiving body. It was hot. In addition, the evaporation part of the heat pipe is accompanied by a heat collecting plate, which makes it difficult to change the orientation of the heat pipe once it is buried, and there are drawbacks such as the need for time-consuming adjustment of the connection with the heat receiving body. In the former case, especially when the heat receiving portion of the heat receiving body has unevenness, heat is dissipated into the air, and the heat transfer effect is significantly impaired.

Therefore, in view of the above circumstances, the present invention was developed for the purpose of effectively retaining and transferring heat energy transported by a heat pipe, regardless of the buried position of the heat pipe. This is achieved by fitting a saucer horizontally rotatably to the apex of the condensing part of the pipe and filling the bottom of the heat receiving element housed in the saucer with a heat medium.

Here, the present invention will be explained with reference to the attached drawings based on an embodiment in which the present invention is used in a water dispenser. As shown in FIG. The bottom of the tray 3 and the bottom of the water meter 4, which is a heat receiving body, are filled with a heat medium 5 (aluminum powder is used as the heat medium in this embodiment). The uneven part on the bottom is completely integrated with the saucer 3, and effectively absorbs and retains the heat radiated from the condensing part apex 2 of the heat pipe 1, and transfers the heat to the water meter 4, thereby preventing the water meter 4 from freezing. At the same time, the evaporation section 6 of the heat pipe 1
Since the heat collecting plate 7 is usually attached to the heat pipe 1 after being buried, it is impossible to change the attitude of the heat pipe 1 itself by rotating it around its axis, but the receiving plate 3 itself cannot rotate horizontally independently. By doing so, the connection position of the water meter 4 can be arbitrarily selected, which also promises labor saving during construction, and the purpose of the present invention can be fully achieved. In this embodiment, the periphery of the water meter 4 is covered with a heat insulating material 8, and the entire upper surface near the opening/closing lid is covered with a room-temperature curing resin 9, and a cap 10 is attached.
