【発明の詳細な説明】熱交換器技術分野本発明は、２つの媒体の間に熱伝達を行わせる熱交換器に関する。熱交換器は、筒状の容器と容器中−プｃｖｙインは、チューブの方向に対して実質的に直角になっている。１つの媒体が容器中をフィン付きチューブの外側を流れ、本５１つの媒体がフィン付きチューブの中を流れる。熱交換器は、特に蒸気凝縮器例えば、蒸気が容器中をフィン付きチューブの外側を流れ冷却媒体がフィン付きチューブ中を流れる熱ポンプ及び類似装置罠使用されるものである。[Detailed description of the invention] Heat exchanger Technical field The present invention relates to a heat exchanger that provides heat transfer between two media. The heat exchanger is The cylindrical container and the cvy in the container are arranged substantially at right angles to the direction of the tube. It has become. A medium flows through the container on the outside of the finned tube, and 51 books medium flows through the finned tube. Heat exchangers, especially steam condensers e.g. , the steam flows through the container and the outside of the finned tube, and the cooling medium flows through the finned tube. Heat pumps and similar devices that flow through the pipes are used.

背景技術熱交換器において、２つの媒体の間に熱伝達を行わせるためにフィン付きチューブを用いることが提案されている。そのような従来技術装置の一例がＩＦＲ２０８３５４７に示されている。フィン付きチューブは、熱伝達面積が大きい仁とが利点である。これらの従来技術による熱交換器は、蒸気の凝縮のために用いることができるが、凝縮物がフィンの表面に付着する欠点があり、このため熱交換器の機能を低下せしめ、凝紬工程の非効率をもたらす。Background technology In a heat exchanger, finned tubes are used to transfer heat between two media. It has been proposed to use An example of such a prior art device is the IFR20 83547. Finned tubes have a large heat transfer area. This is an advantage. These prior art heat exchangers cannot be used for steam condensation. However, it has the disadvantage that condensate adheres to the surface of the fins, so the heat exchanger This reduces the functionality of the pongee and causes inefficiency in the pongee process.

発明の開示本発明の主要な目的は、フィン付きチューブの熱伝達面積が大きい利点を生がしつつ、しかも＃組物が熱伝達面に付着する傾向を無くするか又は少なくとも減少せしめることである。Disclosure of invention The main object of the invention is to take advantage of the large heat transfer area of finned tubes. while eliminating or at least reducing the tendency of the braid to stick to heat transfer surfaces. It is a matter of coercion.

本発明によれば、この目的は請求の範囲に述べられた特徴を有する熱交換器によって達成される。容器はフィン付きチューブの両側に設けられた２つの室に分割されているので、媒体の一方はフィン付きチューブのフィンの間をフィンに充分接触しつつ流れる。かくして、容器中をフィン付きチューブの外側を流れる媒体と、フィン付きチューブの内側を流れる媒体との中に良好な熱伝達が行われる。According to the invention, this object is achieved by a heat exchanger having the features stated in the claims. is achieved. The container is divided into two chambers on either side of the finned tube. so that one side of the medium passes between the fins of the finned tube well enough to reach the fins. Flowing in contact. Thus, the medium flowing outside the finned tube through the container Good heat transfer takes place between the finned tube and the medium flowing inside the finned tube.

チューブのフィンは容器の相対向する２つの壁に接触しているため、フィン付きチューブと容器の間にも良好な熱伝達が行われ、従って、容器もまた熱伝達面を形成し熱交換器を通過する２つの媒体の間の熱交換がざらに向上せしめられる。The fins of the tube are in contact with the two opposing walls of the container, so There is also good heat transfer between the tube and the container, so the container also has a heat transfer surface. The heat exchange between the two media formed and passed through the heat exchanger is greatly improved.

容器の入口端において第１の室がフィン付きチューブの外側にあるスペースのより大きい部分を占め、容器の出口端においてもう一方の室がフィン付きチューブの外側にあるスペースのより大きい部分を占めるようにフィン付キチューブを容器中に対角線上に配置することにより、容器の断面積が小さくても比較的大きい入口管、出口管を設けることができる。かくして、比較的大量の第一媒体を容器に送り込むことができ、２つの媒体間に大量の熱伝達を行わせることが可能となる。At the inlet end of the container, the first chamber is like a space outside the finned tube. the other chamber is a finned tube at the outlet end of the container. Contains finned tubes to occupy a larger portion of the space on the outside of the By arranging the container diagonally, it is relatively large even if the cross-sectional area of the container is small. An inlet pipe and an outlet pipe can be provided. Thus, a relatively large amount of the first medium can be It is possible to transfer a large amount of heat between the two media. Ru.

（３）熱交換器が、蒸気が容器に送り込まれ、冷媒体すなわち冷液体がフィン付きチューブに送り込まれるような蒸気の凝縮に用いられるとき、フィンの間を流れる蒸気はフィン表面から凝縮物を取り除くので、凝縮物がフィンに付着して凝縮を妨げることがない。(3) A heat exchanger is used in which steam is pumped into a vessel and a refrigerant, or cold liquid, is passed through a finned tube. When used to condense steam such as that which is fed into a As the air removes condensate from the fin surface, condensate does not stick to the fins and prevent condensation. I never lose it.

この効果は、容器中の第１の室、すなわち入口室が第２の室、すなわち、出口室の上方に位置しているとき特に顕著である。容器を急なピッチを有する直立したコイルとして設計することにより、凝縮物はコイルの下部に集められ、ζこでフィン付きチューブを囲むことになるので凝縮物は過冷却される。This effect is due to the fact that the first chamber in the container, i.e. the inlet chamber, is connected to the second chamber, i.e. the outlet chamber. This is especially noticeable when located above the . Upright container with steep pitch By designing it as a coil, the condensate is collected at the bottom of the coil and is The condensate is supercooled because it surrounds the finned tube.

本発明による２つの実施例を添付図面を参照しつつより詳しく以下に説明する。Two embodiments according to the invention will be described in more detail below with reference to the accompanying drawings, in which: FIG.

図面の簡単な説明第１図は、真直な容器を有するフィン付きチューブの側面図である。Brief description of the drawing FIG. 1 is a side view of a finned tube with a straight container.

第２図は、第１図のＵ−ＵＳに沿う容器の断面図である。FIG. 2 is a cross-sectional view of the container along U-US in FIG. 1.

第５図は、第１図及び第２図の実施例において容器がコイル状に巻かれた場合の実施例である。Figure 5 shows the case where the container is wound into a coil in the embodiments of Figures 1 and 2. This is an example.

第１図に示される本発明の実施例は、第２図に示されるような実質的に卵型の断面を有する筒状の容器１０を有している。フィン付きチューブ１１は容器１０に挿入される。チューブのフィン１２は、チューブの長手方向に対し実質的に直角に設けられた環状のディスクから成って−る０このタイプのチューブのフィンは、フィンがチューブの一体的部分を形成するように、普通は厚い壁を有するチューブを転造・丸削りして製造される。わるいは、フィンは長手方向にチューブを囲むらせん形に形成することもできる。The embodiment of the invention shown in FIG. It has a cylindrical container 10 having a surface. The finned tube 11 is attached to the container 10. inserted. The fins 12 of the tube are substantially perpendicular to the longitudinal direction of the tube. The fins of this type of tube consist of an annular disc mounted on the , usually thick-walled tubes such that the fins form an integral part of the tube. Manufactured by rolling and rounding the tube. The bad thing is that the fins are connected to the tube in the longitudinal direction. It can also be formed into a surrounding spiral.

フィン付きチューブ１１のフィン１２Ｆｉ、第２図に示すように、容器１００２つの相対向する壁に接触する。The fins 12Fi of the finned tube 11, as shown in FIG. contact two opposing walls.

この接触はフィン付きチューブ１１と容器１０の間に良好な熱伝達を行わせ、かくして、容器内面もまた容器とフィン付きチューブを流れる２つの媒体の間の熱伝達のための熱伝達面となる。容器は、フィン付きチューブよりも大きい断面積を有しているので、フィン付きチューブ１１により２つの室１５．１４　Ｋ分割されており、これらの室は容器の一端から他端へ伸びておりフィン付きチューブの両側に存在している。This contact provides good heat transfer between the finned tube 11 and the container 10, and Therefore, the inner surface of the container also absorbs the heat between the two media flowing through the container and the finned tube. It becomes a heat transfer surface for transfer. The container has a larger cross-sectional area than the finned tube Since it has a finned tube 11, it is divided into two chambers 15.14K. These chambers are made of finned tubes that extend from one end of the container to the other. exists on both sides.

かくして、第１０室１５にはいる媒体は、第２の室１４にはいるためにはフィン１２の間を通過しなければならない。第１図、第２図の実施例においては１容器１０は真直な筒状であり、これに真直な筒状のフィン付きチューブ１１が対角線上に挿入されている。従って、容器の入口側においては、第１の室１５はフィン付きチューブ外側のスペースのより大きい部分を占め、出口側においては第２の室１４がフィン付きチューブの外側のスペースのより大きい部分を占めるこ（５）とになる。このことは、入口側パイプ１５と出口側パイプ１６の取付を便利にする本のである。容器の断面積は小さくても、パイプｉ５，１６は比較的肉厚のものにすることができる。フィン付きチューブ１１もフィン付きチューブを流れる媒体のための入口側パイプ１７と出口側パイプ１８を有しているが、熱交換器において２つの媒体が互いに逆の方向に流れるように容器側の対応するパイプとは入口、出口の関係が逆になっている。媒体の流れの方向は第１図に矢印で示しである。Thus, the medium entering the tenth chamber 15 must pass through the fins in order to enter the second chamber 14. Must pass between 12. In the embodiments shown in Figures 1 and 2, one container is used. 10 has a straight cylindrical shape, and a straight cylindrical finned tube 11 is diagonally opposite to this. inserted above. Therefore, on the inlet side of the container, the first chamber 15 is filled with fins. occupies a larger portion of the space outside the tube with a The chamber 14 occupies a larger portion of the space outside the finned tube (5). ) It becomes. This makes it convenient to attach the inlet pipe 15 and the outlet pipe 16. This is a book about Even though the cross-sectional area of the container is small, the pipes i5 and 16 are relatively thick. can be done. The finned tube 11 also flows through the finned tube. It has an inlet side pipe 17 and an outlet side pipe 18 for the medium, but it is not suitable for the heat exchanger. with corresponding pipes on the container side so that the two media flow in opposite directions to each other. The relationship between the entrance and exit is reversed. The direction of media flow is indicated by the arrow in Figure 1. be.

本発明による熱交換器は、蒸気を凝縮させるのに用いることができる。この場合は、熱交換器の容器は、急なピッチを有する直立したコイルの形にすることが好ましい。この場合の実施例は第６図に示されており、ここでは、第１図のものに対応する各要素には同一の参照符が付しである。フィン付きチューブ１１はこの実施例においても容器１０の対角線上に配置しであるから、容器の出口端にあるフィン付きチューブの連結管１７Ｖｉ容器の上側部分にあり、容器の入口端にある連結管１８は容器の下側部分にある。The heat exchanger according to the invention can be used to condense steam. in this case The heat exchanger vessel is preferably in the form of an upright coil with a steep pitch. Delicious. The embodiment in this case is shown in FIG. 6, and here the one in FIG. Each corresponding element has the same reference numeral. The finned tube 11 is like this Also in the embodiment, since it is arranged diagonally of the container 10, it is located at the outlet end of the container. Connecting pipe of finned tube 17Vi Located in the upper part of the container and at the inlet end of the container. A connecting pipe 18 is located in the lower part of the container.

かくして、容器の第１の室１５は、第２の室１４の上方に位置する。このことは、凝縮工程においては特に便利である。その理由は、蒸気が凝縮物と実質的に同じ方向、すなわち下方へ流れるため、容器を流れる蒸気が凝縮物をフィン表面から取り除くのに有効（６１ｑｉ表口３５自−５００３’／８（３）に寄与するからでおる。容器１０は、急なピッチの直立するコイル状に巻かれているため、凝縮物はコイルの下方部分に集めることができる０従って、比較的少量の凝縮物のみがフィン付きチューブを取り囲むこととなる。このことは凝縮物の過冷却をもたらす、すなわち、凝縮物の温度は凝縮温度以下に下降する。その理由は、フィン付きチューブの中の媒体によりさらに冷却が行なわれるためである。凝縮物の排出のため、コイル下方に出口１９が設けられている。Thus, the first chamber 15 of the container is located above the second chamber 14. This thing is , which is particularly useful in the condensation process. The reason is that steam is essentially the same as condensate. Since the steam flows in the same direction, i.e. downward, the steam flowing through the container will push the condensate away from the fin surface. (61qi surface 35 auto-5003'/8 (3)) Radeol. Since the container 10 is wound into an upright coil with a steep pitch, the condensation Condensate can collect in the lower part of the coil. Therefore, a relatively small amount of condensate The fins will surround the finned tube. This also leads to supercooling of the condensate. ie, the temperature of the condensate falls below the condensation temperature. The reason is that the fi This is because the medium in the tube with the tube provides further cooling. condensate For discharge, an outlet 19 is provided below the coil.

本発明による熱交換器の実施例としては２つのものしか説明しなかったが、本発明の範囲内において多くの異なる実施例及び改変が可能であることは明らかである。すなわち、容器が卵型又は細長い断面を有していることは必ずしも必要ではない。容器は円形の断面にすることもできるが、しかしこの場合に、フィン付きチューブと容器壁の間にゾール材を設ける必要がある。前記のようなシール材は、容器が卵型又は細長い断面を有する場合にも用いることができる。フィン付きチューブは容器の対角線上に設けることは必ずしも必要ではなく、容器の中心線上に設けてもよい。しかし、この場合は、容器は端部が特別の壁によってシールされる必要がわる。図（７）示の実施例においては、容器盾部の閉塞ｓＦｉ、容器を変形させて入口側及び出口側パイプと接するようにして設けることができ、このようにすれば、完全なシールは例えばハンダ付けによ抄行なうことができる。容器がコイル状に巻かれる場合は、少径のコイルに巻くことができるよう罠、容器の細長い断面の長手方向の軸がコイルの軸と平行になるように設けるのが望ましい。しかし、＃細物が容器の全長にわたって流れるように、容器の下部壁はフィンの形と若干異なる形にすることは重要なことである。熱い媒体がフィン付きチューブを流れるようにすれば、結反換器は蒸発のためにも好適に用いることができ国際調査報告Although only two embodiments of the heat exchanger according to the present invention have been described, Obviously, many different embodiments and modifications are possible within the scope of the invention. Ru. In other words, it is not necessarily necessary for the container to have an oval or elongated cross section. do not have. The container can also have a circular cross section, but in this case it can be finned. It is necessary to provide sol material between the tube and the container wall. The sealing material as mentioned above is It can also be used if the container has an oval or elongated cross section. with fins The tube does not necessarily need to be placed diagonally across the container, but rather It may be provided above. However, in this case, the container is sealed at the ends by special walls. The need to be treated is bad. Figure (7) In the embodiment shown, the container shield is closed sFi, the container is deformed, and the inlet and outlet sides are closed. It can be installed so that it is in contact with the mouth side pipe, and in this way, a complete system can be created. The roll can be made, for example, by soldering. The container is wound into a coil. If the trap is an elongated cross-section of the container, it can be wound into a small diameter coil in the longitudinal direction. It is desirable that the axis of the coil be parallel to the axis of the coil. However, #thin items are too small. The bottom wall of the container has a slightly different shape than the fins so that it flows the entire length of the container. It is important to do so. Allow the hot medium to flow through the finned tube. If so, the condensing reactor can also be suitably used for evaporation.
