Description

本発明は、内部に熱媒や冷媒が流通し得る中空部を有し、この中空部を流通する熱媒や冷媒の熱を被熱伝導部材に伝導してこの被熱伝導部材を加熱若しくは冷却する熱伝導用パイプに関するものである。 The present invention has a hollow portion through which a heat medium or a refrigerant can flow, and conducts the heat of the heat medium or the refrigerant flowing through the hollow portion to the heat conductive member to heat or cool the heat conductive member. It is related to the heat conduction pipe.

従来、この種の熱伝導用パイプを用いる技術として、例えば特許文献1に示すような屋根用融雪装置がある。 Conventionally, as a technique using this type of heat conduction pipe, for example, there is a snow melting device for a roof as shown in Patent Document 1.

この屋根用融雪装置は、屋根上に銅板などの伝導性素材板を敷設し、この伝導性素材板上にアルミニウムなどの熱伝導率の高い導管(熱伝導用パイプ)を配設し、この導管に温水を循環させ、導管内を通過する温水の熱を導管の下に敷設した伝導性素材板に伝熱して、この伝導性素材板上の雪を融雪するものである。 In this snow melting device for roofs, a conductive material plate such as a copper plate is laid on the roof, and a conduit (thermal conduction pipe) having high thermal conductivity such as aluminum is arranged on the conductive material plate, and this conduit is provided. Hot water is circulated in the water, and the heat of the hot water passing through the conduit is transferred to the conductive material plate laid under the conduit to melt the snow on the conductive material plate.

ところで、この特許文献1に開示される屋根用融雪装置は、図面(図3)を参酌すると熱伝導用パイプとして円筒状の導管が用いられているが、このような円筒状の導管を用いた場合、導管と伝導性素材板との接触面積が小さいため導管から伝導性素材板に効率よく熱が伝わらない問題がある。 By the way, in the roof snow melting device disclosed in Patent Document 1, a cylindrical conduit is used as a heat conduction pipe in consideration of the drawing (FIG. 3), and such a cylindrical conduit is used. In this case, since the contact area between the conduit and the conductive material plate is small, there is a problem that heat is not efficiently transferred from the conduit to the conductive material plate.

ゆえに、このような平板状の伝導性素材板に熱伝導用パイプからの熱を効率よく伝えるためには、導管と伝導性素材板との接触面積を大きくすることが好ましく、例えば、特許文献2に示すような、外周面の一部に平滑面が形成された断面D形のパイプを用い、この平滑面に融雪板(伝導性素材板)を接合することで、接触面積が大きくなり効率的に熱を伝えることができる。 Therefore, in order to efficiently transfer the heat from the heat conduction pipe to such a flat conductive material plate, it is preferable to increase the contact area between the conduit and the conductive material plate. For example, Patent Document 2 By using a pipe with a D-shaped cross section in which a smooth surface is formed on a part of the outer peripheral surface as shown in, and joining a snow melting plate (conductive material plate) to this smooth surface, the contact area becomes large and it is efficient. Can transfer heat to.

しかしながら、このような断面D形の熱伝導用パイプは、パイプ外形状が円形ではないため、この熱伝導用パイプ同士を連結したり他の配管と連結したりする際に外形状に合った特殊な継手が必要となり、使い勝手やコスト面で懸念がある。 However, since the outer shape of the heat conduction pipe having a D-shaped cross section is not circular, a special shape suitable for the outer shape is used when connecting the heat conduction pipes to each other or to other pipes. There are concerns about usability and cost due to the need for flexible joints.

本発明は、このような現状に鑑みなされたものであり、外周面に平板状の被熱伝導部材が接合される平面部を有し被熱伝導部材に対して効率的に熱伝導可能な構成でありながら、この熱伝導用パイプ同士を連結したり他の配管と連結したりする際に特殊な継手を必要とせずコストが掛からない実用的な熱伝導用パイプを提供することを目的とする。 The present invention has been made in view of such a current situation, and has a configuration in which a flat surface portion to which a flat plate-shaped heat conductive member is joined is provided on the outer peripheral surface so that heat can be efficiently conducted to the heat conductive member.

Similar to the joint member 13 for connecting the heat conduction pipes 8 to each other, a commercially available general joint, specifically, a vinyl chloride cheese joint is used.

以上のように構成される本実施例の作用効果について以下に説明する。 The action and effect of this example configured as described above will be described below.

本実施例の屋根融雪装置は、融雪部9の熱伝導用パイプ8に巾広の平面部4が形成され、この平面部4に融雪板7が接合されているから、熱伝導用パイプ8から融雪板7に地下水熱が効率よく熱伝導され、優れた融雪効果を発揮するものとなる。 In the roof snowmelting device of the present embodiment, since the wide flat surface portion 4 is formed on the heat conduction pipe 8 of the snow melting portion 9 and the snowmelt plate 7 is joined to the flat surface portion 4, the heat conduction pipe 8 is used. Groundwater heat is efficiently conducted to the snowmelt plate 7, and an excellent snowmelt effect is exhibited.

しかも、本実施例の屋根融雪装置は、熱伝導用パイプ8の平面部4の長手方向端部に付設部材2が設けられ、この付設部材2によりパイプ端部の外形状が円筒形(パイプ端部の断面形状が円形)になっているから、すなわち、言い換えると、連結部となるパイプ端部が一般的な円形パイプと同様の形状を呈しているから、熱伝導用パイプ8同士を連結する際や地下水導入管10若しくは地下水導出管11と連結する際に、一般的な円筒状の継手部材(例えば市販されている安価な塩化ビニル製のソケット継手やチーズ継手)を用いて連結することができ、これによりコストを掛けずに簡易に組み立て可能となる。 Moreover, in the roof snow melting device of this embodiment, an attachment member 2 is provided at the longitudinal end of the flat surface portion 4 of the heat conduction pipe 8, and the outer shape of the pipe end is cylindrical (pipe end) due to the attachment member 2. Since the cross-sectional shape of the portion is circular), that is, in other words, the end of the pipe serving as the connecting portion has the same shape as a general circular pipe, the heat conduction pipes 8 are connected to each other. When connecting to the groundwater introduction pipe 10 or the groundwater outlet pipe 11, it is possible to connect using a general cylindrical joint member (for example, a commercially available inexpensive vinyl chloride socket joint or cheese joint). This makes it easy to assemble at no cost.

このように、本実施例の屋根融雪装置は、熱伝導用パイプ8を流通する地下水の熱を融雪板に効率的に熱伝導して優れた融雪効果を発揮すると共に、この熱伝導用パイプ8同士を連結したり他の配管(地下水導入管10や地下水導出管11)と連結したりする際に特殊な継手を必要とせずコストが掛からず簡易に組み立て可能な実用的な屋根融雪装置となる。 As described above, the roof snowmelting device of the present embodiment efficiently conducts the heat of the groundwater flowing through the heat conduction pipe 8 to the snowmelt plate to exhibit an excellent snowmelt effect, and the heat conduction pipe 8 is exhibited. It is a practical roof snowmelting device that can be easily assembled without the need for special joints when connecting to each other or to other pipes (groundwater introduction pipe 10 or groundwater outflow pipe 11). ..

なお、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。 The present invention is not limited to the present embodiment, and the specific configuration of each constituent requirement can be appropriately designed.
