兼太陽熱温水装置に関する。This invention is aimed at houses in areas with heavy snowfall, and uses the same device to melt snow that has accumulated on roofs during the winter snowfall season without having to worry about manual lightning removal work, and also to collect solar heat outside of the snowfall season to provide hot water. This invention relates to a heat pipe type snow melting and solar water heating device that can provide the following.

な原因となっている。In areas with heavy snowfall, snow that has accumulated on the roofs of houses is currently removed by manual labor in most cases. The work involves climbing and is dangerous, and requires considerable hard labor. For this reason, snow removal measures have become a major social issue in areas with heavy snowfall. As a countermeasure to this problem, conventional methods have been to wire electric heaters throughout the roof of the house and use the heat generated by the electricity to melt the snow, or to install lightning pipes on the roof to prevent underground water (
Some methods have been developed and implemented to melt snow by pumping hot water (hot springs) and sprinkling it onto the roof.
These snow melting methods have economic disadvantages such as high equipment and operating costs. To this end, as an alternative to the above-mentioned methods, heat pipes are installed distributed over the roof surface, and heat is applied from the outside to the evaporation section of the heat pipes. 1. A heat pipe type snow melting device that efficiently melts snow accumulated on roofs by giving and receiving latent heat during the cycle has been proposed and its development is progressing. By the way, in each of the conventional snow melting methods mentioned above, the equipment operates only during the snowfall season throughout the year, but it remains idle and does not operate during periods other than the snowfall season, and the operating rate is extremely low. This is a major cause of hindering its widespread use in ordinary homes.

事を含めて施工が簡単に行える利点が得られる。Embodiments of the present invention will be described below with reference to the drawings. First, in Figures 1 and 2, 1 is the roof of the house 2,
A large number of heat pipes 3 are laid in parallel on the left and right along the slope of the roof l. This heat pipe 3 is a long sealed pipe made of a highly thermally conductive material such as copper, and alcohol is placed in the long sealed pipe. It is filled with an anti-freeze working fluid such as Freon that does not freeze at the ambient temperature during the snowfall season, and of the top and bottom parts that protrude vertically from the roof surface, the bottom part is used as the evaporator part 31 in snow melting mode. 31 is equipped with a heater 4 for heat transfer, and the top is a condensation section 32 in solar heat collection mode, and a water heater 5 is disposed in this condensation section for heat transfer. Further, in the roof surface installation area of the heat pipe 3 excluding the bottom and top, there is an aluminum material, for example, which is thermally connected to the sealed pipe and extends from side to side parallel to the roof surface.
Heat receiving fins 33 are equipped. On the other hand, as clearly shown in FIG. 2, the heater 4 includes a heat medium case 41 that collectively surrounds the evaporation section 31 of each heat pipe 3, and the case 41. Heat medium reservoir 42) Water pump 439 For example, it is composed of a heat medium circulation pipe 45 connected between heavy oil-fired boilers 44, and when operating in the snow melting mode, heats the boiler 44 to transfer the heated heat medium. The heat medium is supplied to the heat medium case 41 to apply heat to the evaporation section 31 of the heat pipe 3 from the outside. In addition, outside the snowy season, the heat medium is collected into the reservoir 42 and the heat medium case 41 is kept in an empty and non-operating state.As the heat medium, an antifreeze heat medium 9 such as an ethylene glycol aqueous solution is used. . In addition, the water heater 5 consists of a hot water storage tank 51 that collectively surrounds the condensing section 32 of each heat pipe 3, and a water supply pipe 52 and a hot water supply pipe 53 connected to the hot water storage tank 51. 51 is kept empty and inactive, and water is supplied from the water supply to the hot water tank 51 via the water pump 54 during operation in the solar heat collection mode outside the snowfall season. Note that 55 is a faucet for hot water supply connected to the hot water supply pipe 53. Next, the operation of the heat pipe type snow melting/solar water heating device having the above configuration will be explained. First, as shown in Fig. 3, in the snow melting mode, which melts the snow 6 that has fallen on the roof 1 during the snowfall season, the hot water tank of the water heater 5 is emptied, the water heater is put in the inoperable state as described above, and then Then, the boiler 44 of the heater 4 is fired to heat the heat medium to as high a temperature as possible above 0° C., and this heat medium is circulated to give heat to the evaporation part 31 of the heat pipe 3 inside the heat medium case 41. . As a result, the working fluid evaporates in the heat pipe, the vapor diffuses into the vapor space inside the sealed pipe, and the fin 3
After the heat is radiated to the snow 6 and condensed, it is returned to the evaporation section 31 by gravity. By controlling the evaporation/condensation cycle of the working fluid in this way, the heat given to the evaporation section 31 of the heat pipe 3 through the heater 4 is radiated as latent heat of condensation to the snow 6 that has fallen on the roof surface, effectively removing the snow. Melting snow. The heat transfer during this process is shown by the arrow.Even if there is a large amount of snow, once the snow melting process described above has progressed to a certain extent, the snow accumulated on the roof will cause a surface avalanche and will naturally slide down along the slope of the roof. It becomes like this. On the other hand, outside of the snowy season, the device is used as a solar water heater. In this solar heat collection mode, as shown in FIG. 4, after the heating medium case 41 of the heater 4 is emptied and rendered inactive, water is supplied to the hot water storage tank 51 of the water heater 5 through the water supply pipe 52. In this state, when solar radiation from the sun 7 irradiates the fins of the heat pipe 3 installed on the roof 1, the working fluid of the heat pipe evaporates due to the solar heat and diffuses toward the condensing section 32, causing the water inside the hot water storage tank 51 to evaporate. The evaporation/condensation cycle is repeated in such a way that the water radiates heat and condenses, and then flows down the pipe again.As a result, on the water heater 5 side, the water flowing in the hot water storage tank 51 is heated by the latent heat of condensation of the working fluid. , the hot water supply piping 53. Hot water can be supplied for various purposes through the hot water faucet 55. Regarding the heat pipe 3, as shown in FIG. 5, a wick 35 is attached to the inner peripheral surface of the sealed pipe 34 over the entire length of the heat pipe, and the wick is impregnated with a working fluid. Alternatively, instead of attaching a wick to the heat pipe 3 as shown in FIG.
A heat pipe without a wick is used, in which the heat pipe is filled from the bottom to the middle part of the sealed pipe 34, that is, in a range l corresponding to approximately half the total length of the pipe. In the heat pipe with a wick shown in Fig. 5, the working fluid is sucked up from the bottom by the capillary force of the wick 35, so it not only operates normally in the snow melting mode, but also in the solar heat collection mode. Since the working fluid returns to the area where the heat pipe is installed on the roof, the heat pipe performs an evaporation/condensation cycle using the area where the roof is installed as the evaporator, and thereby works effectively as a solar heat collector. On the other hand, in the heat pipe without a wick shown in Fig. 6, the working fluid 36 is filled in advance up to the middle of the heat pipe. For this reason, the vapor space inside the heat pipe is reduced compared to a heat pipe with a wick, but even in solar heat collection mode, the working fluid is present in approximately half of the roof area of the heat pipe, so there is some heat collection capacity. Although the amount of heat is low, it works effectively as a solar heat collector. Furthermore, the manufacturing cost of this heat pipe without a wick is lower than that of a heat pipe with a wick, and the lack of heat collection capacity in a solar water heater can be compensated for by increasing the number of heat pipes installed. There is no problem in practical use. Next, another embodiment is shown in FIG. 7 and FIG. 8. In this embodiment, a module is constructed of a plurality of heat pipes, whereas in the previous embodiment, each heat pipe 3 is constructed independently. That is, as shown in the figure, the module consists of a plurality of heat pipes 3 arranged in parallel, and each heat pipe 3 has a condensing header pipe 37 at its upper and lower top and bottom parts. They are interconnected through an evaporation header pipe 38. Each of the header pipes 37 and 38 is constructed as a double pipe, and the inner pipe 37a of the condensing header pipe 37 has its inlet side connected to a water supply pipe instead of the hot water tank of the water heater 4 described above, and its outlet side is connected to a separate pipe. Connect piping to the hot water storage tank. On the other hand, the inner pipe 38a of the evaporation header pipe 38 is connected to the heat medium circulation line instead of the heat medium case of the heater 4. In addition, a heat radiation and heat receiving fin 39 is installed at the upper and lower intermediate portions of each heat pipe 3 so as to straddle all the heat pipes in common. In this way, by configuring a module with multiple heat pipes and connecting the modules in series according to the area of the roof when attaching them to the roof of a house, the construction work can be done on a module-by-module basis. It has the advantage of being easy to handle and easy to construct, including piping work.
