この考案は、気液分離された混相状の液化ガスを良好に
気化させるオープンタイプ熱交換器に関する。[Detailed Description of the Invention] This invention relates to an open type heat exchanger that satisfactorily vaporizes multiphase liquefied gas separated into gas and liquid.
従来、液化冷媒を気化する方法として、多数のフィン付
きチューブを垂直に並列し、チューブ上下両端にヘッダ
ータンクを固着して一枚のカーテン状パネルをなす熱交
換部を形威し、液化冷媒を下部ヘッダータンクから導入
し、熱交換部外表面を流れる常温の空気または液体によ
り冷媒に熱を与えて蒸発させ、上部ヘッダータンクより
常温のガスとして送出する熱交換器が使われている。Conventionally, as a method of vaporizing liquefied refrigerant, a large number of finned tubes are arranged vertically in parallel, header tanks are fixed to both the upper and lower ends of the tubes, and a heat exchange section is formed to form a curtain-like panel. A heat exchanger is used in which the refrigerant is introduced from the lower header tank and is heated by room temperature air or liquid flowing on the outer surface of the heat exchanger, causing it to evaporate and then being sent out as room temperature gas from the upper header tank.
ところで、導入する液化冷媒が一部気化した、つまり、
気液相混合の冷媒である場合が多分にあり、上記熱交換

りもフィン付きチューブに速く流入し、各フィン付きチ
ューブの外周面を流れる空気または液体により出口側に
上昇するに従って温度上昇を来たす。By the way, some of the liquefied refrigerant introduced has vaporized, that is,
There are many cases where the refrigerant is a gas-liquid phase mixture, and if it is vaporized in the heat exchanger mentioned above, it will separate into upper and lower two phases when it is introduced into the lower header tank, and the vaporized refrigerant will be more finned than the liquefied refrigerant. Air or liquid quickly flows into the tube and flows around the outer circumferential surface of each finned tube, causing the temperature to rise as it rises toward the outlet side.
一方、液化冷媒は、フィン付きチューブに流入して外部
からの伝達熱量により出口側に上昇するに従って気化さ
れる。On the other hand, the liquefied refrigerant flows into the finned tube and is vaporized as it rises toward the outlet side due to the amount of heat transferred from the outside.
つまり、フィン付きチューブ内の温度分布、流れが非常
に不均一となり、熱交換性能の低下、熱交換器の寿命の
短縮等、種々の不都合を来たすという欠点があった。In other words, the temperature distribution and flow within the finned tube become extremely nonuniform, resulting in various disadvantages such as a reduction in heat exchange performance and a shortened life of the heat exchanger.
更に、上記フィン付きチューブを使用した熱交換器は、
製造コストが高く、伝熱面積の拡大が図れず性能向上に
限界がある等、経済性、実用性に問題があった。Furthermore, the heat exchanger using the above finned tube,
There were problems in terms of economy and practicality, such as high manufacturing costs and the inability to expand the heat transfer area, limiting performance improvement.
この考案は、上記の欠点の解消を目的とするオープンタ
イプ熱交換器を提案するものである。This invention proposes an open type heat exchanger aimed at eliminating the above-mentioned drawbacks.
この考案は、第1図に示す如く、波形フィン1を挾んで

用ヘッダータンク8を該熱交換部4の下端に設けている
。As shown in FIG. 1, this invention consists of two flat plates 2 facing each other with a corrugated fin 1 in between, and a spacer bar 3 closing both ends of the flow path. Fix the header tank 5 and attach the lower header tank 6 to the lower end of the X4.
A header tank 8 for gas-liquid mixing is provided at the lower end of the heat exchange section 4, and a header tank 8 for gas-liquid mixing is provided with a plurality of live tubes 7 protruding from the lower surface in the axial direction.
一方、多数のノズル9を櫛状に突設した小径管10を下
部ヘッダータンク6内に挿入し二重管構造とし、該ノズ
ル9を上記気液混合用ヘツダータンク6の各連結管7内
に空隙をもって同心して挿入し該気液混合用ヘッダータ
ンク6内にノズル9先端を突出させて一体化してなる。On the other hand, a small diameter pipe 10 having a number of nozzles 9 protruding in a comb shape is inserted into the lower header tank 6 to form a double pipe structure, and the nozzles 9 are inserted into each connecting pipe 7 of the header tank 6 for gas-liquid mixing with a gap. The nozzle 9 is inserted concentrically into the gas-liquid mixing header tank 6 with the tip of the nozzle 9 protruding into the header tank 6.
また、下部ヘッダータンク6と小径管10の各々一端を
管端板により閉塞しており、気液相混合液化ガスの導入

上部を前記下部ヘッダータンク6の開口端に、下部を前

ている。In addition, one end of each of the lower header tank 6 and the small diameter pipe 10 is closed by a pipe end plate, and the upper part of an external gas-liquid phase separation drum etc. connected to the gas-liquid phase mixed liquefied gas introduction pipe (not shown) is closed. The lower part is connected to the open end of the lower header tank 6 and the open end of the small diameter pipe 10 via an introduction pipe or the like.
なお、11は散水管、12.13は円環状間隙である。Note that 11 is a water sprinkler pipe, and 12.13 is an annular gap.
上記熱交換器において、散水管11より例えば海水を散

に流入し、分離された液化冷媒を小径管10内に、気化
冷媒を下部ヘッダータンク6の円環状間隙12に導入す
る。In the heat exchanger, for example, seawater is sprinkled from the sprinkler pipe 11, and the seawater is dropped in a film along the heat exchange section 4, and the gas-liquid phase mixed liquefied gas is transferred to a gas-liquid phase separation drum (not shown).
The separated liquefied refrigerant is introduced into the small diameter pipe 10, and the vaporized refrigerant is introduced into the annular gap 12 of the lower header tank 6.
該液化冷媒はノズル9を通って、また気化冷媒は連結管
7とノズル9により形成された円環状間隙13を通って
気液混合用ヘッダータンク8内へ流入する。The liquefied refrigerant flows through the nozzle 9, and the vaporized refrigerant flows into the gas-liquid mixing header tank 8 through the annular gap 13 formed by the connecting pipe 7 and the nozzle 9.
このとき、液化冷媒と気化冷媒の温度差は、下部ヘッダ
ータンク6が二重管構造であるため比較的小さく保て、
また、圧力差も各々、ノズル9と、その外周の円環状間
隙13を別々に通して気液混合用ヘッダータンク8内へ
の流入に対する抵抗を増大させたので、あまり問題にな
らない。At this time, the temperature difference between the liquefied refrigerant and the vaporized refrigerant can be kept relatively small because the lower header tank 6 has a double pipe structure.
Furthermore, the pressure difference does not pose much of a problem because the resistance to the flow into the gas-liquid mixing header tank 8 through the nozzle 9 and the annular gap 13 on its outer periphery is increased.
従って、気液混合用ヘッダータンク8内で液化冷媒と気

る。Therefore, the liquefied refrigerant and the vaporized refrigerant are always uniformly mixed in the header tank 8 for gas-liquid mixing, and the corrugated fins 1 and the flat plate 2
The gas flows into the flow path formed by the gas, is heated by the seawater flowing on the outer surface of the flat plate 2, becomes completely room temperature gas at the upper end of the heat exchange section 4, and is sent out from the upper header tank 5.
