In addition, the dimension of the heat pipe with which the snow melting apparatus for houses of this invention is provided is not limited to this dimension.

  The heat radiating plate 3 is made of an aluminum alloy, and has a rectangular plate shape in which one side is approximately the same length as the length of the chamber 21 and the other side orthogonal to the length is substantially the same as the length of the extension tube 23. Yes. The heat radiating plate 3 is disposed below the extended pipes 23, 23,... In contact with the extended pipes 23, 23, 23,.

  The heat insulating material 4 is composed of urethane foam, self-extinguishing grade bead foam panel, etc., has an upper surface substantially in the same rectangular shape and size as the above-described heat radiating plate 3, and has a slightly lower height than the chamber 21. It has a substantially rectangular parallelepiped shape. The heat insulating material 4 is disposed below the heat radiating plate 3, and a portion in contact with the side portion of the chamber 21 is recessed in a circular arc shape, whereby the recess of the heat insulating material 4 and the side portion of the chamber 21 are formed. Match and touch.

  The heat storage case 5 is made of a Garibarium steel plate and has a rectangular parallelepiped box shape. The height of the heat storage case 5 is slightly larger than the height of the chamber 21, its length is slightly larger than the length of the chamber 21, and its width is larger than the width of the heat pipe 2 (the length of the extension pipe 23). Slightly larger). The heat storage case 5 accommodates the heat pipe 2, the heat radiating plate 3, and the heat insulating material 4 described above. In the heat storage case 5, the extending pipe 23 is arranged in parallel with the upper surface of the heat storage case 5 so as to contact the upper plate of the heat storage case 5. Moreover, a part of both end surface of the thermal storage case 5 has an opening, respectively, and the core pipe 22 protrudes from the opening, respectively. Thus, the heat storage case 5 accommodates the heat pipe 2, the heat radiating plate 3, and the heat insulating material 4, whereby the house snow melting device 1 is configured in a panel shape.

  Further, a plate-shaped snow stopper 51 protrudes from one side of the upper surface of the heat storage case 5 located above the chamber 21.

  The house snow melting apparatus 1 as described above is installed in a house as follows. FIG. 4 is a schematic diagram showing an installation example of the house snow melting apparatus 1 according to the present embodiment. As shown in FIG. 4, the house snow melting device 1 can be installed at the eaves portion of the roof of the house. In the example shown in FIG. 4, the roof 6 of the house is inclined, and the house snow melting device 1 is installed on the upper surface of the roof 6 so that the snow stopper 51 is located on the lower side. That is, in this installation example, the chamber 21 extends in the horizontal direction, and the extending pipes 23, 23, 23,... Are arranged so as to extend upward from the chamber 21 along the inclination of the roof 6. In addition, by installing the house snow melting device 1 on the inclined roof 6 as described above, the core pipe 22 penetrating the inside of the chamber 21 is positioned directly below the central axis of the chamber 21. As a result, the core pipe 22 is disposed at a low position inside the chamber 21, and the core pipe 22 can be surely immersed in the working fluid 21a.

  After the house snow melting apparatus 1 is installed on the roof 6 in this way, by supplying heated water to the core pipe 22, the heated water flows through the core pipe 22, and heat is activated from the heated water. Absorbed by the liquid 21a, the working liquid 21a evaporates. The steam generated in this manner diffuses in the chamber 21 and the extension pipes 23, 23, 23,..., And the heat of the steam is transmitted to the walls of the chamber 21 and the extension pipes 23, 23, 23,. The heat pipe 2 dissipates heat. Further, the vapor is cooled and condensed on the inner wall of the chamber 21 and the extension pipes 23, 23, 23,... And flows downward along the inclination of the extension pipes 23, 23, 23,. Reflux into the chamber 21 located below 23, 23, 23,. In this way, the hydraulic fluid 21a repeats the evaporation / condensation cycle, and heat is released from the entire heat pipe 2. Further, part of the heat released from the extended pipes 23, 23, 23,... Of the heat pipe 2 is transmitted to the heat radiating plate 3. Here, since the heat insulating material 4 is disposed below the heat radiating plate 3, almost no heat is transmitted from the heat radiating plate 3 to the heat insulating material 4, and heat is radiated upward from the heat radiating plate 3. In this way, the heat radiated from the heat pipe 2 and the heat radiating plate 3 is transmitted to the snow accumulated on the upper part of the heat storage case 5, and the snow melting is performed efficiently.

  Further, in the installation example shown in FIG. 4, the house snow melting device 1 is arranged so that the edge of the heat storage case 5 where the snow stopper 51 is provided matches the tip portion (eave portion) of the roof 6. ing. By installing the house snow melting device 1 in this way, the snow accumulated on the upper surface of the house snow melting device 1 is melted, and the snow accumulated on the upper roof portion where the house snow melting device 1 is not installed is dissolved in the house snow melting device. 1, and the snow on the upper surface of the house snow melting device 1 is melted, so that the snow melting can be efficiently performed without installing the house snow melting device 1 on the entire surface of the roof 6. Is possible.

  FIG. 5 is a schematic diagram showing another installation example of the house snow melting apparatus 1 according to the present embodiment. For example, when the area of the roof 6 is large, as shown in FIG. 5, the house snow melting device 1 is installed on the eaves portion of the roof 6 of the house and a part of the upper surface of the roof 6 above it. Can do. By installing the house snow melting device 1 in this way, it becomes possible to melt the snow on the roof 6 more efficiently. Also in this case, since the house snow melting apparatus 1 is installed not only on the entire roof 6 but only on a part thereof, the installation area of the house snow melting apparatus 1 can be reduced as compared with the conventional case, and the cost can be reduced. Reduction is possible.

  In addition, since the extension pipes 23, 23, 23,... Are each formed in a straight tubular shape closed at the tip, less material is required than the structure in which the ends of the extension pipes are connected to each other, and processing is easy. Yes, it is possible to reduce the cost.

  Moreover, since the house snow melting apparatus 1 is comprised by the heat storage case 5 in the shape of a panel, installation of the house snow melting apparatus 1 is easy. Moreover, in the snow melting apparatus 1 for houses which concerns on this Embodiment, since the extension pipes 23, 23, 23, ... are the structures supported only in the connection part with the chamber 21, the intensity | strength of the heat pipe 2 is ensured. Although it is difficult to do so, housing the heat pipe 2 in the heat storage case 5 reduces the risk of breakage of the heat pipe 2 during transportation or installation.

  Furthermore, in the conventional snow melting apparatus in which the heat pipe is exposed, only the heat pipe portion is heated, only the snow in the vicinity of the heat pipe is melted, and unevenness of the snow melting occurs. On the other hand, in the house snow melting apparatus 1 according to the present embodiment, the heat pipe 2 is accommodated in the heat storage case 5, so that the heat released from the heat pipe 2 is diffused throughout the heat storage case 5. Thus, the entire upper surface of the heat storage case 5 is heated, and uneven snow melting can be reduced.
