[0014]
DETAILED DESCRIPTION OF THE INVENTION
The drawings illustrate one embodiment of the present invention and are described below.
[0015]
The present embodiment has a heat radiating portion 1 in a snowy place, a heat exchanging portion 2 in the basement, and connects the heat radiating portion 1 and the heat exchanging portion 2 to form a circulation path 5. The circulating water as the heat exchanger 3 is circulated and the heat obtained by the heat exchange part 2 is radiated in the heat radiating part 1. In this embodiment, circulating water is adopted as the heat exchanger 3. However, any water can be used as long as it exhibits the characteristics of this embodiment.
[0016]
Specifically, in this embodiment, the pipe member is formed in a meandering shape, and this meandering portion is disposed as a heat dissipating portion 1 at a snow accumulation location. In this embodiment, the heat dissipating part 1 is embedded under the road 6, but it may be used with the heat dissipating part 1 exposed on the surface.
[0017]
Moreover, the present Example provides the four heat exchange parts 2, and each this heat exchange part 2 is embed | buried in the parallel state in the predetermined depth position of the underground.
[0018]
As shown in FIG. 1, each of the heat exchange units 2 is configured by providing a passage through which the circulating water 3 passes in a main body 7 in which an appropriate member having good heat conductivity is formed in a long case shape.
[0019]
This passage is divided into an outer passage 9 and an inner passage 10 via a tubular partition member 8 disposed in the main body 7, and the outer passage 9 is at a predetermined position on the upper portion of the main body 7. The circulating water 3 introduced from the introduction part 7a made of an extended pipe member is passed to obtain underground heat (heat exchanged), and the circulating water 3 that has passed through the outer passage 9 is inside. It is configured to be led out from a lead-out portion 7b made of a pipe member that passes through the passage 10 and extends to a predetermined position on the main body 7.
[0020]
Each heat exchanging unit 2 is provided with a lead-in / out regulating mechanism 4 that regulates the lead-in / out of the circulating water 3.
[0021]
The lead-in / out restricting mechanism 4 includes a pair of valve bodies (a first valve body 11 and a second valve body 12) which are provided at a predetermined position in the circulation path 5 and connected to the heat exchange unit 2. The introduction part 7 a of the heat exchange part 2 is connected to the valve body 11, and the lead-out part 7 b of the heat exchange part 2 is connected to the second valve body 12.
[0022]
Each of the first valve body 11 and the second valve body 12 has a three-way valve structure that opens in three directions, and each of the first valve body 11 and the second valve body 12 is operated (setting of the opening direction). Thus, it is configured to allow or prevent the circulating water 3 from being introduced into or removed from the heat exchange unit 2.
[0023]
Specifically, as shown in FIG. 2, the first opening 11a of the first valve body 11 is directed toward the circulation path 5 on the upstream side of the first valve body 11, and the second opening 11b is heated. In the state where the exchange part 2 is directed toward the introduction part 7a, the first opening 12a of the second valve body 12 is directed toward the lead-out part 7b of the heat exchange part 2, and the second opening 12b is second. When the state is directed toward the circulation path 5 on the downstream side of the valve body 12, the circulating water 3 circulating in the circulation path 5 is introduced into the heat exchange section 2 through the introduction section 7a, and then the heat exchange section. The circulating water 3 that has obtained underground heat through 2 is led out to the circulation path 5 through the outlet 7b. At this time, the third openings 11c and 12c are closed.
[0024]
Further, as shown in FIG. 3, the second opening 11b of the first valve body 11 is directed in the direction of the circulation path 5 upstream of the first valve body 11, and the third opening 11c is directed to the first valve body. 11, the third opening 12c of the second valve body 12 is directed toward the circulation path 5 upstream of the second valve body 12, and the first When the opening 12a is in the state of being directed toward the circulation path 5 on the downstream side of the second valve body 12, the circulating water 3 circulating in the circulation path 5 is not introduced into the heat exchanging section 2 and is directly downstream. Will flow to the side. At this time, the first opening 11a and the second opening 12b are closed.
[0025]
Therefore, introduction / restriction mechanism 4 can prevent introduction of circulating water 3 into a part of heat exchanging parts 2, and the remaining heat exchanging part 2 is passed (heat exchanged) to pass circulating water 3. It can be introduced into the heat radiating section 1. In addition, the number of the heat exchange parts 2 is not limited to four, and can be changed in design as appropriate.
[0026]
Reference numeral 13 denotes a control room in which a control device such as a pump connected to an intermediate part of the circulation path 5 is installed.
[0027]
From the above configuration, in this embodiment, when the circulating water 3 circulating in the circulation path 5 passes through the heat exchanging unit 2 disposed underground, the circulating water 3 obtains underground heat, and this heat exchanging unit 2 When the circulating water 3 that has gained heat through the heat dissipating unit 1 disposed at the snow-covered portion, the heat obtained in the heat exchanging unit 2 is dissipated from the circulating water 3 so that snow melting is performed.
[0028]
At this time, when the introduction / restriction mechanism 4 prevents the introduction of the circulating water 3 into some of the heat exchange units 2, the circulating water 3 is introduced into the heat radiating unit 1 through the remaining heat exchange unit 2.
[0029]
Specifically, for example, heat exchange (heat absorption) is not performed in a part of the heat exchange units 2 in which introduction of the circulating water 3 is prevented by the lead-in / out regulation mechanism 4, and heat exchange is performed as illustrated in FIGS. By resting the part 2 in order (the heat exchange part 2 indicated by the dotted line in FIGS. 4 to 7 is a heat exchange part in which the introduction of the circulating water 3 is prevented), the heat recovery of the underground heat is performed. In the meantime, the circulating water 3 is introduced into the heat radiating unit 1 through the remaining heat exchanging unit 2 and the snow melting point is melted. Note that the number of heat exchanging units 2 is not limited to four and is set as appropriate, and the number and order of the heat exchanging units 2 to be rested are also set as appropriate.
[0030]
Therefore, according to the present embodiment, the heat exchange unit 2 in which the circulating water 3 is not introduced among the plurality of heat exchange units 2 is provided (the heat exchange unit 2 that prevents the introduction of the circulating water 3 and rests is provided). Therefore, unlike the conventional structure, heat exchange is not performed without waiting for the heat recovery of the underground heat. Therefore, the circulating water circulating between the heat radiation part 1 and the heat exchange part 2 As for No. 3, underground heat will always be obtained in a good state, and good snow melting will be performed in snowy places.
[0031]
In other words, in the case of the conventional structure in which all the heat exchanging units 2 are operated, since the underground heat is taken away without waiting for the recovery of the underground heat, the heat radiation of the heat radiating unit 1 gradually becomes weak (snow melting will eventually occur). It becomes impossible to stop the apparatus itself completely and wait for the heat recovery of the underground heat.) In this respect, some of the heat exchange units 2 are rested as in this embodiment. (The heat exchanger 2 that operates and the heat exchanger 2 that is rested are appropriately controlled so that sufficient heat recovery of the underground heat is always performed near the heat exchanger 2 and Circulating water 3 that has been sufficiently heat-exchanged in this heat-recovered portion is circulated in the circulation path 5), and as a result, the circulation water 3 that is always sufficient for melting snow in the circulation path 5 (circulation with heat) It becomes possible to circulate water 3), and thus it is necessary to stop the entire apparatus. It is possible to not continuously operate (has been confirmed by experiments the applicant has repeated this regard.).

The present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
