〔産業上の利用分野〕
この発明は蓄熱機能を持たせたループ型ヒートバイブに
関するものである。[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a loop-type heat vibrator having a heat storage function.
周知のように、ループ型ヒートバイブは環状密閉管の内
部に封入した作動流体の蒸発１Ｍ縮を利用して、加熱部

動するものであって、多量の熱を輸送することができる
が、熱を系内にだくわえ、必要に応じて熱を取り出し、
利用できる機能をそれ自身では有していない。そのため
、独立した複数のループ型ヒートバイブと蓄熱槽を組合
せて、熱の蓄熱と放出を行っている。As is well known, a loop type heat vibrator utilizes the 1M evaporation of a working fluid sealed inside an annular sealed tube to transfer heat by circulating the working fluid between a heating section and a cooling section. It is capable of transporting a large amount of heat, but it stores heat within the system and extracts it as needed.
It has no usable functionality on its own. Therefore, multiple independent loop-type heat vibrators and heat storage tanks are combined to store and release heat.
複数のループ型ヒートバイブを用いて、熱をたくわえ利
用する方法では、蓄熱槽の容積が大きくなり、蓄熱槽内
において、熱を放出する周辺の蓄熱材温度と蓄熱材から
熱を取り出すために設けた別のループ型ヒートバイブの
加熱部周辺にある蓄熱材温度との間に大きな温度落差が
生じる。また。In the method of storing and utilizing heat using multiple loop type heat vibrators, the volume of the heat storage tank becomes large. A large temperature drop occurs between the heat storage material and the temperature of the heat storage material around the heating section of another loop-type heat vibrator. Also.
熱をたくわえる間に別のループ型ヒートバイブを通し°
乙外部への熱放散が生じることも避けることができない
。このように、従来の方法では、蓄熱槽容器の寸法増大
、熱効率の低下、操作性の煩雑さ等を招来するなどの問
題がある。While storing the heat, pass it through another loop type heat vibrator.
It is also unavoidable that heat will be dissipated to the outside of the enclosure. As described above, the conventional method has problems such as an increase in the size of the heat storage tank container, a decrease in thermal efficiency, and complicated operability.
本発明は上記の事情に鑑みなされたもので、蓄熱槽容器
の寸法低減、蓄熱能力、熱効率の向上。The present invention was made in view of the above circumstances, and aims to reduce the dimensions of the heat storage tank container, and improve heat storage capacity and thermal efficiency.
熱輸送能力、操作性のすぐれた蓄熱機能を有するループ
型ヒートバイブを提供することを目的としたものである
。The object of the present invention is to provide a loop type heat vibrator having a heat storage function with excellent heat transport ability and operability.
本発明は上記の目的を達成するために、同一系内におい

動流体の蒸発、ｉｔ縮を利用する流路との二つの回路を
構成し、この二つの回路の連結部に蓄熱槽を設けること
により、外部から蓄熱槽までの熱移動は１作動流体の密
度差を利用する流路で行い、蓄熱槽から外部への熱放出
を行う冷却部までの熱移、動は１作動流体の蒸発、凝縮
を利用する流路で行うことを特徴とするものである。In order to achieve the above object, the present invention has two circuits in the same system: a flow path that circulates one working fluid by using the density difference of the working fluid, and a flow path that utilizes evaporation and contraction of the working fluid. By installing a heat storage tank at the connection between these two circuits, heat transfer from the outside to the heat storage tank is performed through a flow path that utilizes the density difference between the working fluids, and heat is released from the heat storage tank to the outside. The heat transfer to the cooling section is carried out in a flow path that utilizes evaporation and condensation of one working fluid.
ループ型ヒートバイブを上記のように構成することによ
り、外部から取り入れる熱は一度蓄熱槽にだくわえられ

態におかれるため、この流路からの熱損失は発生しない
。蓄熱槽内の温度が所定の温度に到達すると、蓄熱槽へ
の熱の移動を中止し、必要な時に、同じ密閉系内の別の
流路を用いる。また、蓄熱槽内での熱の授受部の伝熱管
は同一のものを使用することができるため、蓄熱槽単位
体積当たりの伝熱面積を大きくとることができる。また
、蓄熱槽内の温度も均一に維持でき。By configuring the loop type heat vibrator as described above, heat taken in from the outside is once stored in the heat storage tank. During this time, the circulation flow path from the heat storage tank to the cooler is kept closed, so no heat loss occurs from this flow path. When the temperature in the heat storage tank reaches a predetermined temperature, heat transfer to the heat storage tank is stopped and another flow path within the same closed system is used when necessary. Furthermore, since the same heat transfer tubes can be used in the heat exchange portions within the heat storage tank, the heat transfer area per unit volume of the heat storage tank can be increased. Also, the temperature inside the heat storage tank can be maintained uniformly.
熱効率が高く、装置の小型化が図れるとともに。It has high thermal efficiency and allows for smaller equipment.
操作性も向上することができる。Operability can also be improved.
つぎに本発明の実施例を図面によって説明する。 Next, embodiments of the present invention will be described with reference to the drawings.
