Description

本発明は冷凍サイクルに装備される冷媒の気液分離器に関する。   The present invention relates to a refrigerant gas-liquid separator equipped in a refrigeration cycle.

冷凍サイクルに使用される気液分離器のうちで、冷媒のコンデンサの側面に直接に取付けられる構造を持つ気液分離器が提案されている。
自動車に装備される空気調和機は、エンジンルームの省スペース化に伴い、コンデンサの小型化とともに気液分離器の細径化が求められている。
気液分離器に流入する気液混合冷媒に旋回流を付与して、遠心力により気相冷媒と液相冷媒の分離を助長するものが下記特許文献１に開示されている。
特開２００３−２０２１６８号公報 Among the gas-liquid separators used in the refrigeration cycle, a gas-liquid separator having a structure that is directly attached to the side surface of the refrigerant condenser has been proposed.
Air conditioners installed in automobiles are required to reduce the size of the condenser and to reduce the diameter of the gas-liquid separator as the space in the engine room is reduced.
Patent Document 1 below discloses that a swirl flow is imparted to a gas-liquid mixed refrigerant flowing into the gas-liquid separator to promote separation of the gas-phase refrigerant and the liquid-phase refrigerant by centrifugal force.
Japanese Patent Laid-Open No. 2003-202168

細径の円筒形状の気液分離器を縦長の状態でコンデンサの側面に取付けて、上部から気液混合冷媒を螺旋運動を与えて気液分離器内に流入させると、細径のために、旋回流速が速くなる等の理由によって、旋回流体が気液分離器の底側に溜った液冷媒に衝突し、溜った液を巻き上げることとなる。
この液冷媒の巻き上げは、気液分離性能を低下させる原因となる。
そこで本発明は、上述した不具合を解消する気液分離器を提供するものである。 When a small-diameter cylindrical gas-liquid separator is attached to the side of the condenser in a vertically long state, the gas-liquid mixed refrigerant is given a spiral motion from the top and flows into the gas-liquid separator. For example, the swirling fluid collides with the liquid refrigerant accumulated on the bottom side of the gas-liquid separator, and the accumulated liquid is wound up due to the reason that the swirling flow velocity is increased.
This winding up of the liquid refrigerant causes the gas-liquid separation performance to deteriorate.
Therefore, the present invention provides a gas-liquid separator that eliminates the above-described problems.

本発明の気液分離器は、基本的手段として、円筒形状の本体と、本体の中心部に挿入される気相冷媒の流出パイプと、本体の上部に対して接線方向に取付けられる２相冷媒の流入口と、本体の下部に取付けられる液相冷媒の流出口と、２相冷媒の流入口と液相冷媒の流出口との間の取付けられる冷媒の整流部材を備える。そして、整流部材は遠心分離された冷媒を整流して液相冷媒の貯溜部へ送る機能を備えるものである。   The gas-liquid separator of the present invention includes, as basic means, a cylindrical main body, a gas-phase refrigerant outflow pipe inserted into the center of the main body, and a two-phase refrigerant tangentially attached to the upper portion of the main body. An inflow port of the liquid phase refrigerant, an outflow port of the liquid phase refrigerant attached to the lower portion of the main body, and a refrigerant rectifying member attached between the inflow port of the two phase refrigerant and the outflow port of the liquid phase refrigerant. The rectifying member has a function of rectifying the separated refrigerant and sending the rectified refrigerant to the liquid phase refrigerant reservoir.

本発明の気液分離器は、以上の構成を備えることにより、分離された気冷媒は貯溜部を乱すことなく、気液分離性能を向上することができる。   By providing the gas-liquid separator of the present invention with the above-described configuration, the separated gas refrigerant can improve the gas-liquid separation performance without disturbing the reservoir.

図１は、本発明の気液分離器の構造を示す説明図である。
全体を符号１で示す気液分離器は、細径の円筒形状の本体１０を有し、本体１０内の中央部に気相冷媒の流出パイプ２０を備える。気相冷媒の流出パイプ２０は、本体１０内の上部に開口する気相冷媒の流入口２２と、本体１０の底部から突出する流出口２４を有する。
本体１０の上部には、気相と液相が混合された２相冷媒の流入パイプ３０が取付けられる。この２相冷媒の流入パイプ３０の出口部３２は、円筒形状の本体１０に対して、接線方向に開口するように取付けられる。 FIG. 1 is an explanatory view showing the structure of the gas-liquid separator of the present invention.
The gas-liquid separator generally indicated by reference numeral 1 has a thin cylindrical main body 10, and includes a gas-phase refrigerant outflow pipe 20 in the center of the main body 10.

流入パイプ３０の出口部３２から本体１０の接線方向に流入する２相冷媒Ｒ１は、旋回流を形成し、その遠心力により、比重の大きな液相冷媒Ｒ２と比重の小さな気相冷媒Ｒ３が分離される。
分離された気相冷媒Ｒ３は、気相冷媒流出パイプ２０の流入口２２に流入し、圧縮機側へ送られる。

貯留された液相冷媒Ｒ２は、液相冷媒流出パイプ４０の入口部４２から流出し、膨張弁側へ送られる。
以下、整流部材の複数の実施例を説明する。 The two-phase refrigerant R 1 flowing in the tangential direction of the main body 10 from the outlet portion 32 of the inflow pipe 30 forms a swirl flow, and due to the centrifugal force, the liquid phase refrigerant R 2 having a large specific gravity and the gas phase refrigerant R having a small specific gravity. 3 are separated.
The separated gas-phase refrigerant R 3 flows into the inlet 22 of the gas-phase refrigerant outflow pipe 20 and is sent to the compressor side.
It separated liquid-phase refrigerant R 2 passes through the rectifying member 100 of the present invention to be described later. The liquid phase refrigerant R 2 rectified by the rectifying member 100 is stored in the lower part of the main body 10.
Storing liquid phase refrigerant R 2 flows out from the inlet portion 42 of the liquid-phase refrigerant outlet pipe 40 is sent to the expansion valve side.

図８は、本発明の気液分離器の他の実施の形態を示す説明図である。
全体を符号２００で示す気液分離器は、円筒形状の本体２１０を有し、本体２１０の下部の開口部にはヘッダ２２０が溶接加工部Ｗ１により固着される。
ヘッダ２２０には気相冷媒の流出パイプ２２２が取付けられる。ヘッダ２２０の内側中央部にはボス部２２４が形成され、ボス部２２４の中央に設けた穴にパイプ部材２３０の下端部が差し込まれて、パイプ部材２３０が支持される。 FIG. 8 is an explanatory view showing another embodiment of the gas-liquid separator of the present invention.
The gas-liquid separator generally indicated by reference numeral 200 has a cylindrical main body 210, and a header 220 is fixed to an opening at a lower portion of the main body 210 by a welded portion W 1 .
A gas-phase refrigerant outflow pipe 222 is attached to the header 220. A boss portion 224 is formed at the inner center portion of the header 220, and the lower end portion of the pipe member 230 is inserted into a hole provided in the center of the boss portion 224 so that the pipe member 230 is supported.

本体２１０の上部の中央部には貫通穴２１２が形成され、２相冷媒の流入パイプ２４０が連結される。この流入パイプ２４０の直下には、気液分離部材２５０が配設される。
この気液分離部材２５０は、例えば、樹脂を一体成形してつくられる部材であって、凸部２５４を利用して、パイプ部材２５０の上端部に嵌合される。 A through hole 212 is formed in the central portion of the upper portion of the main body 210, and an inflow pipe 240 for a two-phase refrigerant is connected. A gas-liquid separation member 250 is disposed immediately below the inflow pipe 240.
The gas-liquid separation member 250 is a member made by integrally molding resin, for example, and is fitted to the upper end portion of the pipe member 250 using the convex portion 254.

気液分離部材２５０の上部には、旋回羽根部２６０が設けられる。流入パイプ２４０から貫通穴２１２を通って気液分離器の本体２１０内に流入する２相冷媒は、この旋回羽根部２６０により画成される。
旋回流路２６２内を通過する際に、旋回流となって本体２１０の内部に噴射される。この旋回流の遠心力によって、重量の大きい液相冷媒と、重量の小さな気相冷媒に分離される。 A swirl vane portion 260 is provided on the upper part of the gas-liquid separation member 250. The two-phase refrigerant that flows into the main body 210 of the gas-liquid separator from the inflow pipe 240 through the through hole 212 is defined by the swirl vane portion 260.
When passing through the swirl flow path 262, the swirl flow is injected into the main body 210. The centrifugal force of the swirling flow separates the liquid refrigerant with a large weight and the gas-phase refrigerant with a small weight.

気液分離部材２５０には、スリット２５２が形成されており、このスリット２５２を通って気相冷媒はパイプ部材２３０内に入り、流出パイプ２２２から送り出される。
液相冷媒は貯溜部２３２内に貯溜されるが、前述した整流部材等を設けてもよい。このために、パイプ部材２３０に支持板２３４を設けることもできる。 A slit 252 is formed in the gas-liquid separation member 250, and the gas-phase refrigerant enters the pipe member 230 through the slit 252 and is sent out from the outflow pipe 222.
The liquid-phase refrigerant is stored in the storage unit 232, but the aforementioned rectifying member or the like may be provided. For this purpose, a support plate 234 may be provided on the pipe member 230.

また、液相冷媒の流出口を設けることは、前述の実施例と同様である。
また、気液分離部材２５０のフランジ２５６により、液相冷媒がスリット２５２側へ戻ることが防止される。 In addition, the provision of the liquid-phase refrigerant outlet is the same as in the previous embodiment.
Further, the liquid 256 is prevented from returning to the slit 252 side by the flange 256 of the gas-liquid separation member 250.

図９、図１０は、本発明の気液分離器の更に他の実施の形態を示す説明図である。
全体を符号３００で示す気液分離器は、円筒形状の本体３１０を有する。
図９は、本体３１０の上部の構成のみを示すが、その他の構造は、図８で説明した構造と同様であるので省略する。
本体３１０の上部には、本体３１０の軸線Ｃ１から半径方向にＲ１だけ離れた位置に貫通穴３１２が設けられている。この貫通穴３１２に２相冷媒の流入パイプ３４０が連結される。 9 and 10 are explanatory diagrams showing still another embodiment of the gas-liquid separator of the present invention.
The gas-liquid separator generally indicated by reference numeral 300 has a cylindrical main body 310.
FIG. 9 shows only the configuration of the upper part of the main body 310, but the other structure is the same as the structure described in FIG.
A through hole 312 is provided in the upper portion of the main body 310 at a position separated from the axis C 1 of the main body 310 by R 1 in the radial direction. A two-phase refrigerant inflow pipe 340 is connected to the through hole 312.

本体３１０の軸線Ｃ１上に取付けられるパイプ部材３３０の上端部に対して、気液分離部材３５０が取付けられる。
この気液分離部材３５０は、本体３１０の貫通穴３１２に挿入される冷媒の導入部３６１と、本体３１０の内周面に沿って冷媒を案内するように設けられる旋回通路３６２を有する。 A gas-liquid separation member 350 is attached to the upper end portion of the pipe member 330 attached on the axis C 1 of the main body 310.
The gas-liquid separation member 350 includes a refrigerant introduction portion 361 inserted into the through hole 312 of the main body 310 and a swirl passage 362 provided to guide the refrigerant along the inner peripheral surface of the main body 310.

図１０にも示すように、この旋回通路３６２は、冷媒の導入部の軸心から９０度の範囲にのみ設けられ、導出端３６３で終了する。
流入パイプ３４０、貫通穴３１２を通って本体３１０の軸線に平行に送り込まれる２相冷媒は、この旋回通路３６２により旋回流に変換され、本体３１０の内周面３１１に沿って流れる。 As shown also in FIG. 10, this turning passage 362 is provided only within a range of 90 degrees from the axis of the refrigerant introduction portion, and ends at the outlet end 363.
The two-phase refrigerant fed in parallel to the axis of the main body 310 through the inflow pipe 340 and the through hole 312 is converted into a swirl flow by the swirl passage 362 and flows along the inner peripheral surface 311 of the main body 310.

気液分離部材３５０の冷媒の導入部３６１の軸心に対して、旋回通路３６２とは反対側には、１８０度にわたる傾斜下面３６８が形成してある。
冷媒の旋回流は、この傾斜下面に当って、下向きに偏流され、渦流に変換される。この下向きの渦流にあっては、比重の差により２相冷媒は液相冷媒と気相冷媒に分離される。 An inclined lower surface 368 extending 180 degrees is formed on the opposite side of the swirl passage 362 with respect to the axis of the refrigerant introduction portion 361 of the gas-liquid separation member 350.
The swirling flow of the refrigerant strikes the inclined lower surface and is drifted downward and converted into a vortex flow. In this downward vortex, the two-phase refrigerant is separated into a liquid-phase refrigerant and a gas-phase refrigerant due to the difference in specific gravity.

分離された気相冷媒の気液分離部材３５０のスリット３５２を通ってパイプ部材３３０を介して外部へ送り出される。
気液分離部材３５０のフランジ３５６は、液相冷媒がスリット側へ混入するのを防止する。
分離された液相冷媒は、本体３１０の下部に貯溜され、必要に応じて送り出される。 The separated gas phase refrigerant is sent to the outside through the pipe member 330 through the slit 352 of the gas-liquid separation member 350.
The flange 356 of the gas-liquid separation member 350 prevents liquid phase refrigerant from entering the slit side.
