表面に放熱板12を固着したものである。Many of the disclosed technologies are described in, for example, FIG.
As shown in FIG. 1, a heat transfer tube 10 through which a heat medium flows is disposed on a plate-like heat insulating material 21 such as urethane foam, and a heat radiating plate 12 is fixed to the surface thereof.

【発明が解決しようとする課題】このような融雪パネル

に、熱媒体から放熱板側に如何に有効に熱を伝えるかと
いうことである。ここで、伝熱は輻射(放射)、伝導、
対流によってなされ、従来技術の断熱材はそれらの全て
において一応の満足がいくものである。What is important in the performance of such a snow melting panel P is how to effectively transfer heat from the heat medium to the radiator plate without absorbing the heat to the ground. It is. Here, heat transfer is radiation (radiation), conduction,
Made by convection, prior art insulation is prima facie in all of them.
【0005】しかし、断熱材と言えども熱伝導が皆無と

ネの点で問題がある。[0005] However, even if it is a heat insulating material, it does not mean that there is no heat conduction. At the start of heat transfer, a considerable amount of heat is conducted to the low-temperature side ground due to a temperature difference.

め、その融雪作用の効率が悪い。Further, since a heavy load such as a person or a car is applied to the snow-melting panel, strength in the thickness direction (pressure resistance) is required. In order to obtain this strength with a heat insulating material, the heat insulating material is originally an elastic material, and therefore has a small compressive strength and tends to bend, and if bent, the heat insulating property is reduced due to a decrease in thickness. Regarding this point, Japanese Patent Application Laid-Open No. 7-55167 discloses that a heat radiating plate (frame) has strength in a thickness direction.
The plane shape is shown as a lattice, and a heat transfer tube is arranged in the lattice.In this case, the upper surface that performs the snow-melting action contributes only to the upper end surface of the lattice-shaped heat sink. The efficiency of its snow melting action is poor.
【0007】また、圧縮強度を高めるため、断熱材中に

ため、断熱材の断熱性能が劣化し、地盤側に放熱される
量が多くなる。[0007] In order to increase the compressive strength, there is an insulating material having elasticity by interposing an elastic chip in the heat insulating material.
The chips make the heat insulating material porous, so that the water from the snow melting easily permeates into the heat insulating material.Water has a high thermal conductivity, which degrades the heat insulating performance of the heat insulating material and reduces the amount of heat radiated to the ground side. More.
【0008】そこで、融雪効率の良い融雪パネルが要求

It is necessary to use zinc steel or the like, which is expensive and very expensive to manufacture.
【0010】そこで、この発明では、製作費の低減化も
考え併せ、放熱板を用いない構造とし、放熱板が無くと
も、有る場合と同等の融雪効率をもたらす融雪パネルを
提供することを課題とする。In view of the foregoing, an object of the present invention is to provide a snow melting panel which does not use a heat radiating plate and has the same snow melting efficiency as the case where there is, without a heat radiating plate, in consideration of a reduction in manufacturing cost. I do.

記基板の上面全面に珪砂等の石材を充填し、それらを樹
脂製接着剤で固着してなる融雪パネルを提唱する。According to a first aspect of the present invention, a heating element is provided on an upper surface of a resin substrate having legs formed on a lower surface, and the heating element is covered. It proposes a snow melting panel in which a stone material such as silica sand is filled on the entire upper surface of the substrate, and these are fixed with a resin adhesive.
【0012】このような構成の融雪パネルは、基板が樹
脂であるので断熱性があり、下面の脚が囲む部分は空間
となり、空間(空気)も熱伝導の遮断性が極めて高いの
で、基板上面に配設される発熱体の熱は地盤側には流れ
にくくなっている。In the snow melting panel having such a structure, the substrate is made of a resin and thus has heat insulation. The portion surrounded by the legs on the lower surface becomes a space, and the space (air) has a very high heat-shielding property. The heat of the heating element disposed at the bottom is hard to flow to the ground side.

伝熱効率が悪い。[0013] The surface layer surrounding the heat transfer tube is made of a stone material having a large specific heat, which is solidified with a resin adhesive having a large heat insulating property, so that the heat storage efficiency is high. The heat transfer tube covered over the whole surface,
The heat is efficiently transmitted to the panel surface. On the other hand, a panel having a heat sink, for example, those shown in FIGS.
The heat sink is in line contact with the top surface of the heat transfer tube,
Poor heat transfer efficiency.

As shown in FIG. 4, a holding plate 5 for fixing the heat transfer tube 10 to the large substrate 11 is mounted on the upper surface of the heat transfer tube 10, and the holding plate 5 is provided with a screw hole 2a of the protrusion 2 near the holding plate. And the heat transfer tube 10 is fixed by screws (screw 16b).

To form The filling of the surface layer material 6a and the injection of the adhesive 6b are performed both before placing the holding plate 5 of the heat transfer tube 10 and after placing and fixing.

The upper surface layer 6 (indicated by an arrow pointing upward from the one-dot chain line in the figure) is used for the laying work (connection between the large substrates 11 and heat transfer tubes 10) at the site where the panel P is laid.
At the same time. At that time, in order to make the appearance of the surface layer 6 look natural, natural stone is mixed as the stone material of the surface layer material 6a in addition to the recycled stone and the crushed stone.

The snowmelt flows on the surface of the surface layer 6, but when the surface is constructed so as to have a downward gradient toward the edge of the laying surface, the flow becomes smooth. Also, in this embodiment, as shown in FIG. 1, the substrate 1 has a plurality of holes 4, 4,.
, Flows downward from the hole 4 to the lower side of the substrate 1, and the drainage of the panel P is good. In FIG. 4, since the surface layer 6 is schematically drawn, it seems that the surface layer 6 is densely packed, but there are actually gaps.

In a state where the heat transfer tube 10 is simply provided in the groove 15, the upper surface of the heat transfer tube 10 is slightly raised from the upper surface of the rib 14 or the holding frame 13, and the heat radiating plate 12 is moved to the holding frame 13 (rib 14). When the heat transfer tube 10 is fixed on the upper surface by screwing a bolt 16 b into a screw stand 16 on the rib side wall and fixing the heat sink 12 to the heat sink 12, the heat transfer tube 10 and the groove 15 are pressed against each other.
