この発明は太陽熱コレクタシステムに使用される太陽
熱集熱装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solar heat collecting device used in a solar heat collector system.
従来、この種の太陽熱集熱装置として、両端を端部キ
ャップで気密に閉塞した真空のガラス筒内に、集熱バイ
ブを気密に貫通して集熱筒を形成したものが知られてい
る。BACKGROUND ART Conventionally, as this type of solar heat collecting device, one is known in which a heat collecting tube is formed by passing a heat collecting vibrator airtightly through a vacuum glass cylinder whose both ends are hermetically closed with end caps.
この集熱筒は太陽光をガラス筒内の集熱バイブで吸収し
、その吸収して得た熱を集熱バイブ内に流す熱媒体に熱
伝導してこの熱媒体を加熱するように構成されている。
このような集熱作用中にはガラス筒内が真空に構成され
ていることから、ガラス筒内の真空空間が断熱層となり
、集熱バイブからの熱放散が阻止され、よつて、集熱バ
イブの熱が効果的に熱媒体に熱伝達され、その集熱性能
は高いものである。ところで、このような真空形の集熱
筒にあつては、真空のガラス筒を製造する場合、このガ
ラス筒の長さが必然的に限られることから、熱媒体を高
い温度に加熱しようとすると、１本の集熱筒では充分に
熱媒体を加熱しきれないことがある。This heat collecting tube is configured to absorb sunlight with a heat collecting vibrator inside the glass tube, and heat the heat medium by conducting the absorbed heat to a heat medium flowing inside the heat collecting vibrator. ing.
Since the inside of the glass cylinder is in a vacuum during such heat collecting action, the vacuum space inside the glass cylinder becomes a heat insulating layer, which prevents heat dissipation from the heat collecting vibrator. heat is effectively transferred to the heat medium, and its heat collection performance is high. By the way, in the case of such a vacuum-type heat collecting cylinder, when manufacturing a vacuum glass cylinder, the length of this glass cylinder is inevitably limited, so if you try to heat the heat medium to a high temperature, In some cases, a single heat collecting cylinder cannot sufficiently heat the heat medium.
このため、複数の集熱筒を直列に配置して支持するとと
もにそれぞれの集熱バイブを接続して構成することによ
り、各集熱筒の集熱バイブ内の熱媒体を順次加熱して高
い温度の熱媒体を得ることが考えられる。しかし、この
ように複数の集熱筒を接続して使用するものにあつては
、各集熱筒のガラス筒端部を固定して支持した場合、集
熱作用中におけるガラス筒相互の接離移動やガラス筒全
体の軸方向への変位のためガラス筒の破損を招く不具合
がある。For this reason, by arranging and supporting multiple heat collecting tubes in series and connecting their respective heat collecting vibrators, the heat medium in the heat collecting vibrate of each heat collecting tube is sequentially heated to a high temperature. It is conceivable to obtain a heat medium of However, in cases where multiple heat collecting tubes are connected and used in this way, if the ends of the glass tubes of each heat collecting tube are fixed and supported, the glass tubes may come into contact and separate from each other during heat collection. There is a problem that the glass tube may be damaged due to movement or displacement of the entire glass tube in the axial direction.
すなわち、この種の集熱筒は、通常、集熱バイブが熱伝
導性に優れた金属管で構成されており、しかも集熱作用
中にはガラス筒よりも集熱バイブ．の温度上昇が高くな
るものであるから、集熱バイブとガラス筒との間で熱膨
張差を生じる。In other words, in this type of heat collecting tube, the heat collecting vibrator is usually made of a metal tube with excellent thermal conductivity, and moreover, during the heat collecting action, the heat collecting vibrator has a higher resistance than a glass tube. Since the temperature rise becomes high, a difference in thermal expansion occurs between the heat collecting vibrator and the glass tube.
この熱膨張差による応力発生を防止するため、集熱バイ
ブの少なくとも一端側は、ガラス筒に対してベローズバ
イブなどのような伸縮継手によつて伸縮可、能に支持さ
れている。このような集熱筒を、前述したように隣接す
る集熱バイブ同志を直結して連結した場合、集熱バイブ
とガラス筒間の熱膨張差はガラス筒の軸方向変位により
吸収されることになる。In order to prevent the generation of stress due to this difference in thermal expansion, at least one end side of the heat collecting vibrator is supported so as to be expandable and contractible with respect to the glass tube by an expansion joint such as a bellows vibrator. When such heat collecting tubes are directly connected to adjacent heat collecting vibrators as described above, the difference in thermal expansion between the heat collecting tubes and the glass tubes is absorbed by the axial displacement of the glass tubes. Become.
したがつて隣・接するガラス筒同志では相互に接離する
方向に移動し、またこのような接離が集約されてガラス
筒が軸方向へ移動することになる。このため、ガラス筒
を移動不能に固定してしまうと、上記熱膨張差を吸収で

筒間において集熱バイブ相互を接続する場合、この接続
部付近はガラス筒から露出することになるため、この部
分からの熱損失が大きく集熱効率の低下を招く不具合も
あつた。Therefore, the glass tubes that are adjacent to each other move toward and away from each other, and the glass tubes move in the axial direction as a result of the collective movement of these toward and away from each other. For this reason, if the glass tube is immovably fixed, the above-mentioned difference in thermal expansion cannot be absorbed, leading to breakage of the glass tube. In addition, when connecting the heat collecting vibrators between the glass tubes of each heat collecting tube, the area near this connection will be exposed from the glass tube, so heat loss from this area will be large, leading to a decrease in heat collection efficiency. It was hot too.
この発明はこのような事情にもとづいてなされたもので
、その目的とするところは複数の集熱筒を接続して使用
する場合、ガラス筒の破損を防止ノするとともに、隣り
合うガラス筒間からの熱損失を抑えて集熱効率を高める
ことのできる太陽熱集熱装置を提供することにある。This invention was made based on these circumstances, and its purpose is to prevent damage to the glass tubes when a plurality of heat collection tubes are connected and to prevent damage to the glass tubes, as well as to prevent damage from occurring between adjacent glass tubes. An object of the present invention is to provide a solar heat collection device that can suppress heat loss and increase heat collection efficiency.

を特徴とするものである。That is, the present invention provides a structure in which a plurality of heat collecting tubes are arranged in series and each heat collecting vibrator is directly connected.
The ends of the glass tubes of adjacent heat collecting tubes are connected by a telescopic tube, and the ends of the glass tubes at this connection section are supported by rollers so as to be movable in the tube axis direction. It is something to do.
