一方、蒸気導入口５からは、フロンなどの熱媒体の蒸気

。熱媒［ドの凝縮液は伝熱管３を伝って重力によって降
下し、ケーシング２の下部にある凝縮液排出ロアから排
出される。The steam of the heat medium releases latent heat on the surface of the heat transfer tube 3 through which the cooling water flows; it forms a pseudo-condensation deposit. The cooling water that received heat and was heated externally while rising through the heat exchanger tubes 3 is led out from the cooling water outlet 6. The condensate of the heating medium flows down by gravity through the heat transfer tube 3 and is discharged from the condensate discharge lower located at the bottom of the casing 2.
ところが、伝熱管３の表面には下方に流れる凝縮液の液
膜が生じ、この液膜が新たな蒸気の凝縮を阻害していた
。つまり、伝熱管３の表面に付着した凝縮液の液膜は薄
ければ薄い程、新しい蒸気の凝縮付着にとって望ましい
。そこで、次に述べる熱伝達促進装置は、凝縮液を電場
による作用力で伝熱管３から引き出して除去し、伝熱管
３の表面の液膜を薄くして凝縮を促進させる装置である
。However, a liquid film of the condensate flowing downward was formed on the surface of the heat exchanger tube 3, and this liquid film inhibited the condensation of new vapor. In other words, the thinner the liquid film of condensate adhering to the surface of the heat exchanger tube 3 is, the more desirable it is for new vapor to condense and adhere. Therefore, the heat transfer promoting device described below is a device that draws and removes the condensed liquid from the heat exchanger tubes 3 using the action force of an electric field, thins the liquid film on the surface of the heat exchanger tubes 3, and promotes condensation.
第３図を参照して、金属などの導体から成る伝熱管３の
周囲に、伝熱管３の表面８と間隔をおいて螺旋状に１ｍ
に巻かれた線電極９が、縦方向に伸張する支持体１０に

伝熱管３から離れて縦方向に伸張する排液体１２に接続
されている。Referring to FIG. 3, a 1 m spiral pattern is formed around the heat exchanger tube 3 made of a conductor such as metal at a distance from the surface 8 of the heat exchanger tube 3.
A wire electrode 9 wound around the wire electrode 9 is supported by a support 10 extending in the longitudinal direction. The terminal end 11 of the line electrode 9 is
It is connected to a drain liquid 12 extending vertically away from the heat exchanger tube 3 .
伝熱管３を一方の電極とし、且つ線電極９を他方の電極

排出される。When the heat exchanger tube 3 is used as one electrode and the wire electrode 9 is used as the other electrode, and a high voltage is applied between the two, the condensate liquid flows from the surface 8 of the heat exchanger tube 3 to the wire electrode 9 as shown in FIG. be drawn towards. The condensate flows down along the spiral wire electrode 9,
The centrifugal force of the flowing condensate overcomes the force caused by the electric field,
It is connected to the drain liquid 12 and flows downward along the drain liquid 12. Then, the condensate discharge lower is discharged to the outside of the casing 2.
（発明が解決しようとする問題点）
上記、従来の凝縮熱交換器における熱伝達促進装置では
、１重の線電極９を多段に設置して用いていた。(Problems to be Solved by the Invention) In the above-mentioned conventional heat transfer promoting device for a condensing heat exchanger, single wire electrodes 9 are installed in multiple stages.
凝縮液の排出をできるだけ多くするためには、螺旋状の
線電極９をできるだけ密に巻回するほうが効果的である
。そこで、図の螺旋状の線電極９を上側と下側の２重（
２本）とし、他の構成をそのままとして、これを伝熱管
３の回りに多段に巻回したものを実装してみた。In order to discharge as much condensate as possible, it is more effective to wind the spiral wire electrode 9 as tightly as possible. Therefore, the spiral wire electrode 9 shown in the figure is connected to the upper and lower sides (
2), and with the other configurations unchanged, we mounted a package in which these were wound around the heat exchanger tube 3 in multiple stages.
ところが、２重螺旋の線電極９では、上側の線電極９で
殆どの凝縮液を引き出してしまうため、下側の線電極９

よって線電極９に付着したままとなる。即ち、凝縮液が
線電極９から排液体１２に移行しないのである。However, in the double spiral wire electrode 9, most of the condensate is drawn out by the upper wire electrode 9, so the lower wire electrode 9
Only a small amount of condensate is drawn out. Therefore, the centrifugal force of the condensate flowing down the wire electrode 9 due to gravity does not exceed the force exerted by the electric field, and the condensate remains attached to the wire electrode 9 due to the force exerted by the electric field. That is, the condensed liquid does not transfer from the wire electrode 9 to the drained liquid 12.
本発明は上記公知の電場による伝熱促進装置を改良した

（実施例）
以下に、本発明の一実施例を第１国を参照して説明する
。(Example) An example of the present invention will be described below with reference to a first country.

ロンなどの熱媒体の蒸気が潜熱を放出し、その表面に凝
縮付着する。一方、冷却水は、受熱して昇温する。3 is a heat transfer tube provided in the R position within the condensing heat exchanger. Cooling water flows inside the heat transfer tube 3. Steam of a heat medium such as fluorocarbon releases latent heat to the heat transfer tube 3, and condenses and adheres to the surface of the heat transfer tube 3. On the other hand, the cooling water receives heat and rises in temperature.
ところが、伝熱管３の表面には下方に流れる凝縮液の液

る。However, a liquid film of the condensate flowing downward is formed on the surface of the heat transfer tube 3, and this liquid film hinders the condensation of steam in places. Therefore, the heat transfer promoting device of the present invention for removing the condensate on the surface 8 of the heat transfer tube 3 using an electric field is provided as follows.

、伝熱管３の上端から下端まで複数組が多段に設けられ
ている。The heat exchanger tube 3 is made of a conductor such as a metal (ζ), and around the heat exchanger tube 3, with a distance from the surface 8, there are wire electrodes 9a, 9b wound in a double spiral, vertically. It is supported by a support 10 extending in the direction. A plurality of sets of wire electrodes 9a and 9b are provided in multiple stages from the upper end to the lower end of the heat exchanger tube 3.
第１図では、説明を簡単化するため、上段Ｘ、下段Ｙの
２組の線電極が図示されているが、この実施例に限定さ
れるものではない。又、伝熱管３の断面形状は、円形に
限定されない。In FIG. 1, two sets of line electrodes, an upper stage X and a lower stage Y, are illustrated to simplify the explanation, but the invention is not limited to this embodiment. Moreover, the cross-sectional shape of the heat exchanger tube 3 is not limited to a circle.

表面８の１疑縮液は線電極９ａ、９ｂ側に引き出される
。本発明において線電極９ａ、９ｂが２重に巻かれてい
るのは、−重の線電極より凝縮液の引き出し量を多くす
るためである。A high voltage is applied between the heat exchanger tube 3 as one electrode and the wire electrodes 9a and 9b as the other electrode, and the liquid condensate on the surface 8 of the heat exchanger tube 3 is drawn out to the wire electrodes 9a and 9b side. . The reason why the wire electrodes 9a and 9b are wound twice in the present invention is to draw out a larger amount of condensate than the negative wire electrode.
伝熱管３と線電極９ａ、９ｂの接触してショートするの
を防止するため、伝熱管３と線電極９ａ、９ｂの間隔を
保持する絶縁材料から成るスペーサを設けてもよい。In order to prevent a short circuit due to contact between the heat exchanger tube 3 and the wire electrodes 9a, 9b, a spacer made of an insulating material may be provided to maintain the distance between the heat exchanger tube 3 and the wire electrodes 9a, 9b.
引き出された凝縮液は螺旋状の線電極９ａ、９ｂに沿っ
て下方に流れていくが、本実施例では、線電極９ａ、９
ｂの螺旋の傾斜が、下方にいくに従って急角度に形成さ

。The drawn condensate flows downward along the spiral wire electrodes 9a, 9b, but in this embodiment, the wire electrodes 9a, 9
The slope of the spiral b is formed at a steeper angle as it goes downward, increasing the acceleration of the condensate and increasing the centrifugal force.
上側の線電極９ａの終″４１１ａは、伝熱管３から離れ
て縦方向に伸張する排液体１２に接続されている。The terminal end 411a of the upper wire electrode 9a is connected to the drained liquid 12 extending vertically away from the heat exchanger tube 3.
ところが、下側の線電極９ｂは、上側の線電極９ａに比
べ引き出す凝縮液の量が少ないので、線電極９ｂを伝わ

くならず、線電極９ｂと伝熱管３の表面８の両方にまた
がって付着した状ｆｉ（第４図参照）で移動し、途中で
停止して排液体１２の方に離れて流れていかない。However, since the lower line electrode 9b draws out less amount of condensate than the upper line electrode 9a, the centrifugal force when flowing down the line electrode 9b is not large enough to reach the drained liquid 12, and the line It moves in a state of adhesion fi (see FIG. 4) spanning both the electrode 9b and the surface 8 of the heat exchanger tube 3, stops midway, and does not flow away toward the drained liquid 12.
そのため、上段Ｘにおける下側の線電極９ｂの終端が下
段Ｙの上側の線電極９ａの始端に接続され、上段Ｘの下
側の線電極９ｂを伝わる凝縮液が下段Ｙの上側の線電極
９ａを介して排液体１２に連絡されるように構成されて

施例に限定されるものではなく、上段Ｘにおける下側の

９ａの始端に連絡するように植成してもよい。Therefore, the terminal end of the lower line electrode 9b in the upper stage The drain liquid 12 is configured to be connected to the drain liquid 12 via the drain liquid 12 . Since the upper line electrode 9a draws out a large amount of condensate as described above, the centrifugal force acting on the condensate is large, and the condensate can reach the drained liquid 12. It should be noted that the present invention is not limited to the above-mentioned embodiments, and may be implanted so that the terminal end 11b of the lower line electrode 9a in the upper stage X is connected to the starting end of the lower line electrode 9a in the lower stage Y. good.
本実施例は、次のように作用する。This embodiment operates as follows.
伝熱管３を一方の電極とし、且つ線電極９ａ。The heat exchanger tube 3 is used as one electrode, and the wire electrode 9a.
９らを他方の電極として両者間に高電圧をかける。そう
すると、伝熱管３が面状で線電極が線状なので両者間に
不平等電界が形成され、伝熱管３の表面８の凝縮液の分
子に線電極９ａ、９ｂ向きの力が作用し、；疑縮液を線
電極９ａ、９ｂ側に引き出す。A high voltage is applied between the electrodes 9 and 9 as the other electrode. Then, since the heat exchanger tube 3 is planar and the wire electrode is linear, an unequal electric field is formed between them, and a force in the direction of the wire electrodes 9a and 9b acts on the molecules of the condensate on the surface 8 of the heat exchanger tube 3; The pseudocondensate is drawn out to the wire electrodes 9a and 9b.
線電極９ａ、９ｂが２重に巻かれているため、−重の線
電極よｒ）凝縮液の引き出し量が多い。Since the wire electrodes 9a and 9b are wound twice, the amount of condensate drawn out is larger than that of the double wire electrode.
上側の線電極９ａに引き出された２疑縮液は、遠心力に

極９ａを介して排液体１２に連絡され、排液体１２を流
下して下方に伝わる。The liquid drawn to the upper line electrode 9a is transmitted on the line electrode 9a by centrifugal force, is connected to the drained liquid 12, and is transmitted downward through the drained liquid 12 by gravity. Further, the condensate drawn out to the lower line electrode 9b in the upper stage flows down and is transmitted downward.
線電極９ａ、９ｂの螺旋の傾斜が下方にいくに従って急
角度となり凝縮液に作用する遠心力が増加されているの
で、線電極９ａから排液本１２への連絡が確実に行え、
途中で昂止してしまうことがない。Since the spiral slope of the wire electrodes 9a and 9b becomes steeper as it goes downward, the centrifugal force acting on the condensate is increased, so that the wire electrode 9a can be reliably connected to the drain main 12.
There is no stopping mid-way.
（発明の効果）
既に述べたとおり、単純に２重螺旋の線電極を設置した
ものでは、下側の線電極に付着した凝縮液は量が少ない
ので、凝縮液に作用する遠心力が電ｊ易による作用力よ
りも小さくなって、凝縮液は排出されない。(Effects of the Invention) As already mentioned, in the case where a double spiral wire electrode is simply installed, the amount of condensate adhering to the lower wire electrode is small, so the centrifugal force acting on the condensate is The condensate is not discharged because the force is smaller than the force exerted by the force.
ところが、本発明では、線電極が上下２重に螺線状に巻
かれ、下側の線電極の終端が下段の線電極の始端に接続
されているので、下側の線電極に付着した凝縮液の量が
少なかったとしても、その凝縮液を下段の線電極の始端
に与えて、下段で排出することができるものとなる。However, in the present invention, the wire electrode is spirally wound in two layers, upper and lower, and the terminal end of the lower wire electrode is connected to the starting end of the lower wire electrode, so that condensation attached to the lower wire electrode is removed. Even if the amount of liquid is small, the condensed liquid can be applied to the starting end of the lower line electrode and discharged at the lower level.
このため、伝熱管の表面から多くの凝縮液を引き出すこ
とが可能となり、凝縮熱交換器の伝熱促進効果を一層向
上させることができるものである。Therefore, it becomes possible to draw out a large amount of condensate from the surface of the heat exchanger tube, and the heat transfer promoting effect of the condensing heat exchanger can be further improved.
