Description
【０００１】[0001]
本考案は、自動車用空気調和装置などの冷房サイクルに組み込まれるリキッド タンクに関する。 The present invention relates to a liquid tank incorporated in a cooling cycle of an air conditioner for a vehicle.
【０００２】[0002]
一般に、自動車用空気調和装置は、冷房サイクル中の余剰冷媒の貯留、気液分 離あるいは水分、塵埃の除去等を行うためのリキッドタンクを有している（例え ば、実開昭５８−１０８，３８０号公報）。 Generally, an air conditioner for an automobile has a liquid tank for storing excess refrigerant, separating gas and liquid, or removing water and dust during a cooling cycle (for example, the actual opening 58-108). , 380).
【０００３】 従来のリキッドタンク１は、図４に示すように、有底筒状のタンク本体部２と 、このタンク本体部２の上部開口３を閉塞するヘッド部４とを有している。As shown in FIG. 4, a conventional liquid tank 1 has a bottomed cylindrical tank main body 2 and a head 4 for closing an upper opening 3 of the tank main body 2.
【０００４】 ヘッド部４には、冷媒入口部５と冷媒出口部６とが形成されており、この冷媒 入口部５の一端にはコンデンサに連通する入口導管１６が接続され、他端はタン ク本体部２の内部空間と連通されている。また、冷媒出口部６は、一端に膨張弁 と接続される出口導管１７が接続され、他端に冷媒取出管７が取付けられるＬ字 状の通路であり、タンク本体部２の底部２ｃに貯溜した液冷媒のみを取出すため に、タンク本体部２の底部２ｃ近傍まで垂下している。また、冷媒取出管７の上 方には、冷媒出口部６内の冷媒流動状態を目視するためのサイトグラス８が設け られており、冷媒取出管７の下方には、冷媒が流通する乾燥剤充填部９が設けら れている。乾燥剤充填部９は、多数の小孔１０が開設された上支持板１１と下支 持板１２とを有し、これら支持板１１，１２の間には、乾燥剤１４およびグラス ウール等からなるフィルタ１５が下支持板１２により包まれるように収容されて いる。A refrigerant inlet portion 5 and a refrigerant outlet portion 6 are formed in the head portion 4, one end of the refrigerant inlet portion 5 is connected to an inlet conduit 16 communicating with a condenser, and the other end thereof is connected to a tank. It communicates with the internal space of the main body 2. The refrigerant outlet portion 6 is an L-shaped passage having an outlet conduit 17 connected to an expansion valve at one end and a refrigerant outlet pipe 7 attached at the other end, and is stored in the bottom portion 2c of the tank body portion 2. In order to take out only the generated liquid refrigerant, it is hung down to near the bottom portion 2c of the tank body 2. Further, a sight glass 8 for visually observing the flow state of the refrigerant in the refrigerant outlet 6 is provided above the refrigerant take-out pipe 7, and below the refrigerant take-out pipe 7, a desiccant in which the refrigerant flows. A filling section 9 is provided. The desiccant filling section 9 has an upper support plate 11 and a lower support plate 12 in which a large number of small holes 10 are formed. Between the support plates 11 and 12, the desiccant 14 and glass wool are used. The filter 15 is housed so as to be wrapped by the lower support plate 12.
【０００５】 特に、近年、冷媒の気液分離性を高める観点から、冷媒取出管７の中間位置に 偏流部材２０が設けられている。偏流部材２０は、外方ほど降下するテーパ面２ １を有し、その最外周に設けられた複数の突起２２によりタンク本体部２の内周 面に取付けられている。タンク本体部２内に流入した媒体は、気液混合状態であ り、偏流部材２０のテーパ面２１に衝突したり、これに沿って流されてタンク本 体部２の内周面に衝突し、流速を弱められ、これにより気液が分離されつつ偏流 部材２０とタンク本体部２との間の隙間２３を通って下方の乾燥剤充填部９に導 かれる。In particular, in recent years, from the viewpoint of improving the gas-liquid separation property of the refrigerant, a drift member 20 is provided at an intermediate position of the refrigerant outlet pipe 7. The drift member 20 has a tapered surface 21 that descends toward the outside, and is attached to the inner peripheral surface of the tank body 2 by a plurality of protrusions 22 provided on the outermost periphery thereof. The medium that has flowed into the tank main body 2 is in a gas-liquid mixed state and collides with the tapered surface 21 of the drift member 20 or is flowed along this and collides with the inner peripheral surface of the tank main body 2. The flow velocity is weakened, whereby the gas-liquid is separated and guided to the lower desiccant filling section 9 through the gap 23 between the drift member 20 and the tank body 2.
【０００６】[0006]
このようにタンク本体部２内に偏流部材２０を設けることにより冷媒の気液分 離を促進すると、この隙間２３により冷媒は圧力損失を生じ、気液分離が促進さ れないこともあり、偏流部材２０を設けているにも拘らず、冷房能力の向上を図 れないという問題があり、加えて、凝縮時の冷媒の圧力および温度が高くなり、 液化される冷媒の量が相対的に減少し、冷媒封入量を削減できないという問題も ある。 When the gas flow-liquid separation of the refrigerant is promoted by providing the non-uniform flow member 20 in the tank main body 2 as described above, the refrigerant loses pressure due to the gap 23, and the gas-liquid separation may not be promoted. Despite the provision of the member 20, there is a problem in that the cooling capacity cannot be improved. In addition, the pressure and temperature of the refrigerant during condensation increase, and the amount of liquefied refrigerant decreases relatively. However, there is also a problem that the amount of refrigerant enclosed cannot be reduced.
【０００７】 本考案は、このような従来技術の問題点に鑑みてなされたものであり、冷媒の 圧力損失を極力少なくしながら冷媒の気液分離を促進し、これにより、冷房能力 の向上を図ると共に封入冷媒量を低減したリキッドタンクを提供することを目的 とする。The present invention has been made in view of the above problems of the prior art, and promotes gas-liquid separation of the refrigerant while minimizing the pressure loss of the refrigerant, thereby improving the cooling capacity. It is an object of the present invention to provide a liquid tank in which the amount of filled refrigerant is reduced and the amount of the enclosed refrigerant is reduced.
【０００８】[0008]
上記目的を達成すべく本考案は、有底筒状をしたタンク本体部の上部開口をヘ ッド部により閉塞し、このヘッド部に設けた冷媒入口部と前記タンク本体部内に 設けられた乾燥剤充填部との間に、流入した冷媒をタンク本体部内で側方に偏流 させタンク本体部の内周壁と衝突させる偏流部材を有し、前記タンク本体部の下 部に貯溜した液冷媒を冷媒取出管を介して前記ヘッド部の冷媒取出口から流出す るようにしたリキッドタンクにおいて、前記偏流部材は、径方向の所定位置より 外方に向って降下する外方テーパ部と、前記所定位置より内方に向って降下する 内方テーパ部とを有し、この偏流部材とタンク本体部の内周面および冷媒取出管 との間に各々隙間を設けたことを特徴とするリキッドタンクである。 In order to achieve the above object, the present invention closes the upper opening of a tank body having a bottomed cylindrical shape with a head, and a refrigerant inlet provided in the head and a drying unit provided in the tank body. Between the agent filling section and the agent filling section, there is a drift member that biases the inflowing refrigerant laterally in the tank body section and collides with the inner peripheral wall of the tank body section. In a liquid tank configured to flow out from a refrigerant outlet of the head portion via an outlet pipe, the drift member includes an outer taper portion that descends outward from a predetermined radial position and the predetermined position. A liquid tank having an inner taper portion that descends further inward, and a gap is provided between the drift member and the inner peripheral surface of the tank main body and the refrigerant outlet pipe. ..
【０００９】[0009]
このように構成したリキッドタンクでは、冷媒は、偏流部材の内方あるいは外 方に設けられた隙間を通って流下するので、外方テーパ部のみならず内方テーパ 部によっても気液分離が促進される。しかも冷媒は、偏流部材とタンク本体部の 内周面との隙間のみならず、偏流部材と冷媒取出管との隙間からも下方に導かれ るため、冷媒が流れ易く、偏流部材上方での圧力が高くなることがなく、冷媒の 圧力損失を低減でき、気液分離がより一層促進される。したがって、冷媒能力の 向上を図ることができ、凝縮時の冷媒の圧力および温度が低下し、液化する冷媒 の量が増大し、この結果、封入冷媒量も低減できる。 In the liquid tank configured as described above, the refrigerant flows down through the gap provided inside or outside the drift member, so that the gas-liquid separation is promoted not only by the outer tapered portion but also by the inner tapered portion. To be done. Moreover, since the refrigerant is guided downward not only through the gap between the drift member and the inner peripheral surface of the tank main body but also through the gap between the drift member and the refrigerant outlet pipe, the refrigerant easily flows and the pressure above the drift member is increased. Does not increase, the pressure loss of the refrigerant can be reduced, and gas-liquid separation is further promoted. Therefore, the refrigerant capacity can be improved, the pressure and temperature of the refrigerant at the time of condensation are reduced, and the amount of liquefied refrigerant is increased. As a result, the amount of enclosed refrigerant can be reduced.

In addition, “29” indicates an O-ring for enhancing the airtightness between the inlet conduit 16 and the outlet conduit 17 and the head portion 4. Further, the head portion 4 is formed with a sight glass 8 for visually observing the state of the refrigerant flowing through the refrigerant outlet portion 6, and a pressure switch 27 for detecting the pressure of the refrigerant in the liquid tank 20.
【００１４】 タンク本体部２の下方において、ヘッド部４から垂下した冷媒取出管７に、乾 燥剤充填部９が固着されている。この乾燥剤充填部９は、その収納容器として、 上蓋部材１１と、これの下側にかしめ等により嵌合された有底筒状のカップ部材 １２とを備えている。この上蓋部材１１の上面には、冷媒を乾燥剤充填部３０内 に導くための多数の小孔１０が形成されていると共に、カップ部材１２の底面に も、乾燥剤充填部９内から冷媒を下方に導くための多数の小孔１０が形成されて いる。この乾燥剤充填部９内には、乾燥剤１４が封入されており、さらにこれの 下方にフィルタ１５が配置されている。乾燥剤１４は冷媒中の水分を吸着する働 きをし、例えば、シリカゲルや合成ゼオライトなどが用いられる。フィルタ１５ は、ここを通過する冷媒中の塵埃を除去する働きをすると共に、乾燥剤１４が車 載時の振動から破砕するのを防止する緩衝材しての働きをし、グラスウール等が 用いられる。A desiccant filling section 9 is fixed to a refrigerant take-out pipe 7 hanging from the head section 4 below the tank main body section 2.

【００１５】 特に、本実施例では、冷媒入口部５と触媒充填部９との中間位置に、断面逆Ｗ 字状の偏流部材３０が設けられている。この偏流部材３０は、図２にも示すよう に、タンク本体部２の内周面に対して径方向外方ほど降下するようなテーパ面で ある外方テーパ部３１と、冷媒取出管７の外周面に対して径方向内方ほど降下す るようなテーパ面である内方テーパ部３２とから構成されている。In particular, in this embodiment, a drift member 30 having an inverted W-shaped cross section is provided at an intermediate position between the refrigerant inlet portion 5 and the catalyst filling portion 9. As shown in FIG. 2, the non-uniform flow member 30 includes an outer taper portion 31 which is a taper surface that descends radially outward with respect to the inner peripheral surface of the tank body 2, and the refrigerant outlet pipe 7. It is composed of an inner taper portion 32 which is a taper surface which is lowered radially inward with respect to the outer peripheral surface.
【００１６】 外方テーパ部３１の外方下端には、タンク本体部２の内周面との間に所定の隙 間３３を形成する環状面３５が設けられている。この環状面３５には、タンク本 体部２の内周面に圧接して取り付けるための複数の突起３６が設けられている。 内方テーパ部３２の内方下端には、冷媒取出管７の外周面との間に所定の隙間３ ４を形成する環状面３７が設けられている。この環状面３７には、冷媒取出管７ の外周面に圧接して取り付けるための複数の突起３８が設けられている。At the outer lower end of the outer tapered portion 31, an annular surface 35 is provided which forms a predetermined gap 33 with the inner peripheral surface of the tank body 2. The annular surface 35 is provided with a plurality of protrusions 36 for press-fitting and attaching to the inner peripheral surface of the tank main body 2. An annular surface 37 that forms a predetermined gap 34 with the outer peripheral surface of the refrigerant outlet pipe 7 is provided at the inner lower end of the inner tapered portion 32. The annular surface 37 is provided with a plurality of projections 38 for being pressed against and attached to the outer peripheral surface of the refrigerant outlet pipe 7.
【００１７】 次に、実施例の作用を説明する。 コンプレッサから吐出された冷媒は、コンデンサ内で凝縮されるが、常に完全 に液化されるものではなく、気液混合状態の冷媒もリキッドタンク内に流入する ことになる。この冷媒は、入口導管１６およびヘッド部４の冷媒入口部５よりタ ンク本体部２内に流入する。この気液混合状態の冷媒は、偏流部材３０の外方テ ーパ部３１および内方テーパ部３２に沿って流れ、タンク本体部２の内周面およ び冷媒取出管７の外周面に衝突し、偏流部材３０とタンク本体部２および冷媒取 出管７との間の隙間３３，３４を通して下方の乾燥剤充填部９に導かれる。Next, the operation of the embodiment will be described. Although the refrigerant discharged from the compressor is condensed in the condenser, it is not always completely liquefied, and the refrigerant in a gas-liquid mixed state also flows into the liquid tank. This refrigerant flows into the tank body 2 through the inlet conduit 16 and the refrigerant inlet portion 5 of the head portion 4. The refrigerant in the gas-liquid mixed state flows along the outer taper portion 31 and the inner taper portion 32 of the nonuniform flow member 30, and flows to the inner peripheral surface of the tank main body 2 and the outer peripheral surface of the refrigerant outlet pipe 7. It collides and is guided to the desiccant filling section 9 below through the gaps 33, 34 between the drift member 30 and the tank main body 2 and the refrigerant discharge pipe 7.
【００１８】 このように、本実施例では、気液混合状態にある冷媒は、外方テーパ部３１の みならず、内方テーパ部３２によっても気液分離が促進されることになるが、し かも本実施例では、冷媒は、偏流部材３０とタンク本体部２の内周面との隙間３ ３のみでなく偏流部材３０と冷媒取出管７との隙間３４からも下方に導かれる。 このため、従来と異なり冷媒通路が拡がり冷媒が流れ易く、偏流部材上方での圧 力が高くなることがなく、冷媒の圧力損失を低減でき、気液分離をより一層促進 することができる。したがって、冷媒能力の向上を図ることができ、凝縮時の冷 媒圧力および温度も低下することになり、液化する冷媒量が増大し、結果的に冷 媒封入量が低減できる。As described above, in the present embodiment, the refrigerant in the gas-liquid mixed state promotes gas-liquid separation not only by the outer taper portion 31 but also by the inner taper portion 32. However, in this embodiment, the refrigerant is guided downward not only from the gap 33 between the drift member 30 and the inner peripheral surface of the tank body 2, but also from the gap 34 between the drift member 30 and the refrigerant outlet pipe 7. For this reason, unlike the conventional case, the refrigerant passage is expanded and the refrigerant easily flows, the pressure above the non-uniform flow member is not increased, the pressure loss of the refrigerant can be reduced, and the gas-liquid separation can be further promoted. Therefore, the capacity of the refrigerant can be improved, the pressure and temperature of the cooling medium at the time of condensation are also lowered, the amount of the liquefied refrigerant is increased, and as a result, the amount of the sealed cooling medium can be reduced.
【００１９】 そして、乾燥剤充填部９に流入した冷媒は、乾燥剤充填部３０内に流下し、乾 燥剤１４により冷媒中の水分が吸着され、フィルタ１５により冷媒中の塵埃が除 去される。次いで、液冷媒は、リキッド本体部２の底部２ｃに貯溜され、その後 、冷媒取り出管７により取り出され、冷媒出口部６から出口導管１７を介して膨 脹弁に導かれる。Then, the refrigerant flowing into the desiccant filling section 9 flows down into the desiccant filling section 30, the moisture in the refrigerant is adsorbed by the desiccant 14, and the dust in the refrigerant is removed by the filter 15. It Next, the liquid refrigerant is stored in the bottom portion 2c of the liquid main body 2, then taken out by the refrigerant take-out pipe 7, and guided from the refrigerant outlet part 6 to the expansion valve via the outlet conduit 17.
【００２０】 なお、本考案は、上述した実施例に限定されるものではなく、例えば、偏流部 材３０は、図１，２に示す単なる逆Ｗ字状のみでなく、図３に示すように、外方 テーパ部３１および内方テーパ部３２をジグザグにしてもよい。この場合には、 冷媒の通路が増大しより一層圧力損失を削減することができる。The present invention is not limited to the above-described embodiment. For example, the drift member 30 is not limited to the mere inverted W shape shown in FIGS. The outer taper portion 31 and the inner taper portion 32 may be zigzag. In this case, the passage of the refrigerant is increased, and the pressure loss can be further reduced.
【００２１】[0021]
以上述べたように、本考案に係るリキッドタンクによれば、冷媒は、外方テー パ部のみならず、内方テーパ部によっても気液分離され、偏流部材とタンク本体 部との間の隙間のみならず、偏流部材と冷媒取出管との間の隙間からも流下する ので、冷媒が流れ易く、偏流部材上方での圧力が高くなることがなく、冷媒の圧 力損失を削減することができる。これにより、気液分離をより一層促進すること ができ、冷媒能力が向上し、凝縮時の冷媒圧力および温度が低下し、液化する冷 媒の量が増大し、封入冷媒量を低減できる。 As described above, according to the liquid tank of the present invention, the refrigerant is gas-liquid separated not only by the outer taper portion but also by the inner taper portion, so that the gap between the drift member and the tank body portion is increased. Not only that, it also flows down from the gap between the non-uniform flow member and the refrigerant outlet pipe, so that the refrigerant easily flows, the pressure above the non-uniform flow member does not increase, and the pressure loss of the refrigerant can be reduced. .. As a result, the gas-liquid separation can be further promoted, the refrigerant capacity can be improved, the refrigerant pressure and temperature at the time of condensation can be lowered, the amount of the liquefied cooling medium can be increased, and the amount of the enclosed refrigerant can be reduced.
