本発明は蓄熱剤中を熱交換器チューブが通過する潜熱蓄
熱装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a latent heat storage device in which a heat exchanger tube passes through a heat storage agent.
第１図に示される如く従来の潜熱蓄熱装置は、蓄熱槽１
０内へ水等の蓄熱剤１２が充填されており、この蓄熱剤
ｌ２内を熱交換器チューブｌ４が貫通している。この熱
交換器チューブｌ４の両端はへラダｌ６を介して蓄熱媒
体搬送管１８．１９へ連通している。As shown in FIG. 1, the conventional latent heat storage device has a heat storage tank 1.
0 is filled with a heat storage agent 12 such as water, and a heat exchanger tube 14 passes through the heat storage agent 12. Both ends of this heat exchanger tube l4 communicate with heat storage medium conveying pipes 18, 19 via a ladder l6.
このような従来の潜熱蓄熱装置において、蓄熱媒体搬送

た逆に放熱する場合には０℃以上のプラインを熱交換器
チューブｌ４へ通して水を融解しプラインの温度を下げ
るようになっている。In such a conventional latent heat storage device, when cold heat storage is performed using water as the heat storage agent 12 by sending a pline from the heat storage medium transport pipe 18, the pline at a temperature of 0°C or less is sent from the heat storage medium transport pipe 18 to the header-16. The heat exchanger tube 14 passes through the heat exchanger tube 14, and after exchanging heat with water, it passes through the transfer pipe 19 and is discharged to the outside of the heat storage tank. As the water passes through this pline, the heat storage agent releases latent heat and solidifies, thereby storing cold heat. On the other hand, when heat is to be radiated, the pline at a temperature of 0° C. or higher is passed through the heat exchanger tube l4 to melt the water and lower the temperature of the pline.
ところがこのような従来構造では冷蓄熱時に凝固した氷

熱剤である水との間の熱抵抗が増大し、単位時間当たり
の伝熱量が減少する不具合を有している。この結果蓄熱
槽内の水が全て凝固して蓄熱を完了するまでに長時間の
熱交換作業が必要となっている。However, in such a conventional structure, ice that solidifies during cold heat storage adheres to the surface of the heat exchanger tube 140, increasing thermal resistance between the plines and water as a heat storage agent, and reducing the amount of heat transferred per unit time. It has a defect. As a result, a long heat exchange operation is required until all of the water in the heat storage tank solidifies and heat storage is completed.
本廃明は上記事実を考慮し、蓄熱、放熱時間を短縮する
ことができる潜熱蓄熱装置を得ることが目的である。Taking the above facts into consideration, the purpose of this invention is to obtain a latent heat storage device that can shorten the heat storage and heat radiation time.
本発明に係る潜熱蓄熱装置は交換器チコーーブを長手方
向に伸ｉ可能とし、駆動装置でこの熱交換器チューブを
長手方向に伸縮させて熱交換器中に付着した氷を破壊、
剥離するようになっている。The latent heat storage device according to the present invention enables the exchanger tube to be extended in the longitudinal direction, and uses a drive device to expand and contract the heat exchanger tube in the longitudinal direction to destroy ice adhering to the heat exchanger.
It is designed to peel off.
以下本発明の実施例を図面に従い説明する。Embodiments of the present invention will be described below with reference to the drawings.
第２図に示される本実施例では、従来例と同様この蓄熱

の長手方向（第２図左右方向）に駆動してヘッダ２２を
ヘッダ２０と接離させるようになっている。Further, one end of a connecting rod 26 is fixed to the header 22, and the other end of this connecting rod 26 is connected to a drive device 28 installed outside the heat storage tank. The drive device 28 may be a hydraulic cylinder, for example, and is adapted to drive the connecting rod 26 in its longitudinal direction (in the left-right direction in FIG. 2) to move the header 22 toward and away from the header 20.
なお連結棒２６の中間部は蓄熱槽１０を［通しているが
、この貫通部には蓄熱槽内の蓄熱剤が漏洩じ−ないよう
に適切なシール構造が採用されている。The intermediate portion of the connecting rod 26 passes through the heat storage tank 10, and an appropriate sealing structure is adopted at this penetrating portion to prevent the heat storage agent in the heat storage tank from leaking.
ヘッダ２０には蓄熱媒体搬送管３０が連通されて図示し
ない供給源から蓄熱媒体であるプラインをヘッダ２０へ
送り込むことができるようになつケ
与へラダ２２から熱交換後の蓄熱媒体を蓄熱媒体供給源
へ循環させるようになっている。A heat storage medium conveying pipe 30 is connected to the header 20 so that a pline, which is a heat storage medium, can be sent from a supply source (not shown) to the header 20.The heat storage medium after heat exchange is supplied from the ladder 22 to the header 20. It is designed to circulate back to the source.
一対のヘッダ２０．２２は複数本（この実施例では４本
）の熱交換器チューブ３４で連通されており、これらの
チューブ３４はヘッダ２０ 、２２と共に熱交換器を構
成している。The pair of headers 20 and 22 are communicated by a plurality of (four in this embodiment) heat exchanger tubes 34, and these tubes 34 together with the headers 20 and 22 constitute a heat exchanger.
これらの熱交換器チューブ３４はその長手方向（第２図

ダ２２と蓄熱媒体搬送管３２との間も蛇腹構造とされて
ヘッダ２２の移動に対処している。These heat exchanger tubes 34 are serpentine return tubes that can be expanded and contracted in the longitudinal direction (horizontal direction in FIG. 2), and are connected to the header 20.2.
The header 22
It is designed to expand and contract as you move. Note that a bellows structure is also formed between the header 22 and the heat storage medium conveying pipe 32 to cope with movement of the header 22.
このように構成された本実施例の作動手順を説明する。The operating procedure of this embodiment configured in this way will be explained.
図示しない供給源からのブラインを蓄熱媒体搬送管３０
からヘッダ２０へ送り込れば、プラインは熱交換器チュ
ーブ３４へ至り、蓄熱剤である水と熱交換し水が潜熱を
放出する。熱交換後のブラインはへラダ２２、蓄熱媒体
搬送管３２を経て図示しない供給源へ循環される。Brine is supplied from a supply source (not shown) to the heat storage medium conveying pipe 30.
When fed into the header 20, the pline reaches the heat exchanger tube 34, where it exchanges heat with water, which is a heat storage agent, and the water releases latent heat. The brine after heat exchange is circulated to a supply source (not shown) via the spatula 22 and the heat storage medium conveying pipe 32.
これと同時に駆動装置２８を連続運転して連結棒２６を
往復運動させる。これによってヘッダ２２は連続的にヘ
ッダ２０と接離運動を繰り返し、熱交換器チューブ３４
が伸縮動作を繰り返す。At the same time, the drive device 28 is continuously operated to cause the connecting rod 26 to reciprocate. As a result, the header 22 continuously repeats the movement toward and away from the header 20, and the heat exchanger tube 34
repeats the expansion and contraction movement.

ーブ外表面は常に蓄熱剤１２が接触する状態となる。こ
の結果プラインと水の熱交換が促進され、蓄熱時間が短
縮される。Therefore, due to heat exchange in the heat exchanger tube 34, ice adhering to the outer periphery of the tube 34 is peeled off from the tube, and the outer surface of the tube is always in contact with the heat storage agent 12. As a result, heat exchange between the prine and the water is promoted, and the heat storage time is shortened.

Further, the drive device 28 is not limited to the structure provided outside the heat storage tank, but can also be provided above the heat storage tank, inside the heat storage tank, and omit the seal provided between the connecting rod and the heat storage tank.
