Description

本発明は、加圧式リザーブタンクに関し、詳しくは、その耐圧構造の改良に関する。   The present invention relates to a pressurized reserve tank, and in particular, to an improvement in its pressure resistance structure.

従来、ラジエータ内の冷却水の量及び内圧調整を行うため、エンジンとラジエータの間の冷却水回路に加圧式リザーブタンクを設ける技術が公知になっている（特許文献１、２参照）。   2. Description of the Related Art Conventionally, a technique for providing a pressurized reserve tank in a cooling water circuit between an engine and a radiator in order to adjust the amount of cooling water in the radiator and internal pressure is known (see Patent Documents 1 and 2).

このような加圧式リザーブタンクは、加圧キャップを備えてタンク本体内にも圧力が掛かる構造として外気を遮断し、冷却水を完全に密封している。
従って、開放式のリザーブタンクに比べて、リザーブタンクを冷却水回路の一部とすることで、全冷却水を常に循環させることにより外気との接触を無くして、蒸発による冷却水の減少や外気接触による劣化の防止を図ることができる。
また、冷却水回路内の気泡をリザーブタンク内で気体と液体に分離できるため、気液分離性能の向上が図れる等の効果が得られる。
さらに、タンク本体の内部は、通常、複数の仕切り壁によって格子状の室に区画されており、気液混合の冷却水が各仕切り壁に設けられたスリットを介して室同士間を自由に流通することにより気液分離する構造となっている。
実開昭６１−９４２３２号公報 特開平６−１４６８８３号公報 Such a pressure type reserve tank is provided with a pressure cap and has a structure in which pressure is also applied to the inside of the tank body to block outside air and completely seal the cooling water.
Therefore, compared to an open-type reserve tank, by making the reserve tank a part of the cooling water circuit, all the cooling water is constantly circulated to eliminate contact with the outside air, thereby reducing the cooling water due to evaporation and the outside air. It is possible to prevent deterioration due to contact.
In addition, since the bubbles in the cooling water circuit can be separated into gas and liquid in the reserve tank, effects such as improvement of gas-liquid separation performance can be obtained.
Furthermore, the interior of the tank body is usually partitioned into a lattice-like chamber by a plurality of partition walls, and the cooling water for gas-liquid mixing freely circulates between the chambers through slits provided in each partition wall. By doing so, it has a structure for gas-liquid separation.

しかしながら、従来の加圧式リザーブタンクにあっては、タンク本体の内部が、複数の仕切り壁によって格子状の室に区画されるため、内圧によって応力が集中する部位が発生して亀裂・破損する虞があった。   However, in the conventional pressurized reserve tank, the inside of the tank main body is partitioned into a lattice-like chamber by a plurality of partition walls, and there is a risk that a portion where stress is concentrated by internal pressure may be generated and cracked or damaged. was there.

そこで、仕切り壁の厚みをより厚く形成したり、スリットを浅く形成して剛性を上げることが考えられるが、この場合、材料コストや重量が増加する上、気液分離性能が悪化してしまう。   Thus, it is conceivable to increase the rigidity by forming the partition wall thicker or forming the slit shallower, but in this case, the material cost and weight increase and the gas-liquid separation performance deteriorates.

And a slit is provided in the cylindrical wall to communicate with a chamber adjacent to the chamber in the cylindrical wall.

先ず、全体構成を説明する。
図１〜３に示すように、本実施例１の加圧式リザーブタンクは、タンク本体Ａが上部容器１と下部容器２で構成されている。 First, the overall configuration will be described.
As shown in FIGS. 1 to 3, in the pressurization type reserve tank of the first embodiment, the tank body A is composed of an upper container 1 and a lower container 2.

図３、４に示すように、上部容器１は、中央に配置された円筒状の上部円筒壁３と、この上部円筒壁３から外側へ放射状に伸びる４つの上部仕切り壁４ａ〜４ｄで５つの上部タンク槽５ａ〜５ｅに区画され、その下端の開口周縁には鍔状のフランジ部Ｆ１が形成されている。
また、上部円筒壁３の下端には、所定の深さを有する縦長のスリット６ａ〜６ｄがそれぞれ形成されると共に、これらスリット６ａ〜６ｄを介して上部タンク槽５ａが各タンク槽５ｂ〜５ｅとそれぞれ連通した状態になっている。
さらに、上部タンク槽５ｂに連通して側方へ筒状に突出する入力ポートＰ１が設けられ、上部タンク槽５ｄに連通して上方へ筒状に突出する加圧キャップ取り付け口Ｃ１が形成されている。 As shown in FIGS. 3 and 4, the upper container 1 includes a cylindrical upper cylindrical wall 3 disposed in the center and four upper partition walls 4 a to 4 d extending radially outward from the upper cylindrical wall 3. The upper tank tanks 5a to 5e are partitioned, and a flange-like flange portion F1 is formed on the opening periphery of the lower end thereof.
In addition, longitudinal slits 6a to 6d having a predetermined depth are formed at the lower end of the upper cylindrical wall 3, and the upper tank tank 5a is connected to the tank tanks 5b to 5e via the slits 6a to 6d. Each is in communication.
Further, an input port P1 that communicates with the upper tank tank 5b and protrudes in a cylindrical shape is provided, and a pressure cap attachment port C1 that communicates with the upper tank tank 5d and protrudes in a cylindrical shape is formed. Yes.

図３、５に示すように、下部容器２は、上部容器１と同様に、中央に配置され、且つ、円筒状の下部円筒壁７と、この下部円筒壁７から外側へ放射状に伸びる４つの下部仕切り壁８ａ〜８ｄで５つの下部タンク槽９ａ〜９ｅに区画され、その上端の開口周縁にはフランジ部Ｆ２が形成されている。
また、下部円筒壁７の上端には、所定の深さを有する縦長のスリット１０ａ〜１０ｄがそれぞれ形成されると共に、これらスリット１０ａ〜１０ｄを介しての下部タンク槽９ａが各タンク槽９ｂ〜９ｅとそれぞれ連通した状態になっている。
また、上部容器１と下部容器２を重ね合わせた際に、スリット６ａ〜６ｄとスリット１０ａ〜１０ｄは重ならない位置に形成されている。
さらに、下部タンク槽９ｄに連通して側方へ筒状に突出する出力ポートＰ２が設けられている。 As shown in FIGS. 3 and 5, the lower container 2 is arranged at the center, like the upper container 1, and has a cylindrical lower cylindrical wall 7 and four radially extending outwards from the lower cylindrical wall 7. The lower partition walls 8a to 8d are partitioned into five lower tank tanks 9a to 9e, and a flange portion F2 is formed at the opening periphery of the upper end thereof.
In addition, longitudinal slits 10a to 10d having a predetermined depth are formed at the upper end of the lower cylindrical wall 7, and the lower tank tank 9a through the slits 10a to 10d is connected to the tank tanks 9b to 9e. Are in communication with each other.
Further, when the upper container 1 and the lower container 2 are overlapped, the slits 6a to 6d and the slits 10a to 10d are formed at positions where they do not overlap.
Furthermore, an output port P2 that communicates with the lower tank tank 9d and projects in a cylindrical shape to the side is provided.

そして、上部容器１と下部容器２は、それぞれ樹脂を材料として上下金型により成形され、上部容器１のフランジ部Ｆ１と下部容器２のフランジ部Ｆ２を加熱溶融して両者を最中状に重ね合わせることにより、両フランジ部F1,F2、両円筒壁3,7、両仕切り壁４ａ〜４ｄ,８ａ〜８ｄが溶着接合されることにより、タンク本体Ａが一体的に形成されている。   Then, the upper container 1 and the lower container 2 are respectively molded by the upper and lower molds using resin as a material, and the flange part F1 of the upper container 1 and the flange part F2 of the lower container 2 are heated and melted so that both are stacked in the middle. By combining the two flange portions F1, F2, the two cylindrical walls 3, 7, and the two partition walls 4a-4d, 8a-8d, the tank body A is integrally formed.

従って、図６に示すように、タンク本体Ａの内部は、両円筒壁3,7で形成される円筒壁１１の内側に室１３ａが設けられ、両仕切り壁４ａ〜４ｄ、８ａ〜８ｄで形成される４つの仕切り壁１２によって４つの室１３ｂ〜１３ｅが設けられている。   Therefore, as shown in FIG. 6, the inside of the tank body A is provided with a chamber 13a inside the cylindrical wall 11 formed by both cylindrical walls 3 and 7, and is formed by both partition walls 4a to 4d and 8a to 8d. Four chambers 13 b to 13 e are provided by the four partition walls 12.

また、図７に示すように、上部容器１と下部容器２を接合すると、スリット６ａ〜６ｄの下端開口が仕切り壁８ａ〜８ｄによって塞がれた長孔形状となると同時に、スリット１０ａ〜１０ｄの上端開口が仕切り壁４ａ〜４ｄの下端によって塞がれた孔形状になり、これによって、室１３ａは長孔形状のスリット６ａ〜６ｄ、１０ａ〜１０ｄを介して各室１３ｂ〜１３ｅに連通状態になっている。   Moreover, as shown in FIG. 7, when the upper container 1 and the lower container 2 are joined, the lower end openings of the slits 6a to 6d become a long hole shape closed by the partition walls 8a to 8d, and at the same time, the slits 10a to 10d. The upper end opening has a hole shape closed by the lower ends of the partition walls 4a to 4d, whereby the chamber 13a communicates with the chambers 13b to 13e through the long hole-shaped slits 6a to 6d and 10a to 10d. It has become.

従って、本実施例１のタンク本体Ａの内部は、中央に配置され、且つ、略円筒状に形成された円筒壁１１と、この円筒壁１１から外側へ放射状に伸びる仕切り壁１２で複数の室１３ａ〜１３ｅに区画され、円筒壁１１に室１３ａと隣接する室１３ｂ〜１３ｅを連通状態にするスリット６ａ〜６ｄ、１０ａ〜１０ｄが形成されることとなる。   Accordingly, the inside of the tank main body A of the first embodiment has a plurality of chambers including a cylindrical wall 11 disposed in the center and formed in a substantially cylindrical shape, and a partition wall 12 extending radially outward from the cylindrical wall 11. The slits 6a to 6d and 10a to 10d are formed in the cylindrical wall 11 to communicate the chambers 13b to 13e adjacent to the chamber 13a.

次に、作用を説明する。
このように構成された加圧式リザーブタンクは、図８に示すようなエンジン２０とラジエータ２１の間に設けられた冷却水回路の途中にラジエータ２１と並列に加圧式リザーブタンクが介装される。 Next, the operation will be described.
The pressurized reserve tank configured as described above is provided with a pressurized reserve tank in parallel with the radiator 21 in the middle of a cooling water circuit provided between the engine 20 and the radiator 21 as shown in FIG.

具体的には、加圧式リザーブタンクの入力ポートＰ１がエンジンから排出される冷却水回路側に接続され、出力ポートＰ２がエンジンへ流入する冷却水回路側のサーモスタット２２とウォーターポンプ２３の間に接続される。   Specifically, the input port P1 of the pressurized reserve tank is connected to the cooling water circuit side discharged from the engine, and the output port P2 is connected between the thermostat 22 on the cooling water circuit side flowing into the engine and the water pump 23. Is done.

そして、タンク本体Ａ内には、加圧キャップ取り付け口Ｃ１に装着された加圧キャップＣによって例えば１ｋｇ／ｃｍ2前後の内圧が掛けられる他、入力ポートＰ１から室１３ｂに流入した気液混合の冷却水は、スリット6a,10aを介して室１３ａに流入し、さらに、室１３ａの冷却水は、スリット６ｂ〜６ｄ、１０ｂ〜１０ｄを介して各室１３ｃ〜１３ｅに同時に流入して各室１３ａ〜１３ｅを流通する間に拡散して完全に気液分離された後、出力ポートＰ２から排出される。 In the tank body A, an internal pressure of, for example, about 1 kg / cm 2 is applied by the pressure cap C attached to the pressure cap attachment port C1, and the gas-liquid mixture flowing into the chamber 13b from the input port P1 is applied. The cooling water flows into the chamber 13a through the slits 6a and 10a, and the cooling water in the chamber 13a simultaneously flows into the chambers 13c to 13e through the slits 6b to 6d and 10b to 10d. ˜13e is diffused during circulation and completely gas-liquid separated and then discharged from the output port P2.

ここで、従来の発明にあっては、タンク本体の内部が、複数の仕切り壁によって格子状の室に区画されるため、内圧によって応力が集中する部位が発生し、この部位が亀裂・破損する虞があった。
なお、上記亀裂・破損が生じた場合、本実施例１の加圧式リザーブタンクは最終的に両フランジ部F1,F2の溶着部位が剥がれて内部の冷却水が漏れる虞がある。 Here, in the conventional invention, since the inside of the tank body is partitioned into a lattice-like chamber by a plurality of partition walls, a portion where stress is concentrated by the internal pressure is generated, and this portion is cracked / damaged. There was a fear.
In the case where the above-mentioned crack / breakage occurs, the pressurized reserve tank of the first embodiment may eventually peel off the welded portions of both flange portions F1 and F2 and leak the cooling water inside.

しかしながら、本実施例１の加圧式リザーブタンクにあっては、タンク本体Ａの内部を、円筒壁１１と仕切り壁１２で複数の室１３ａ〜１３ｅに区画したため、内圧を円筒壁１１から外側へ均等に分散させて応力集中を避けることができ、従来品よりも優れた耐圧構造を実現できる。   However, in the pressurization type reserve tank of the first embodiment, the inside of the tank main body A is partitioned into the plurality of chambers 13a to 13e by the cylindrical wall 11 and the partition wall 12, so that the internal pressure is evenly distributed from the cylindrical wall 11 to the outside. It is possible to avoid the concentration of stress by dispersing it in a layer and to realize a pressure-resistant structure superior to that of the conventional product.

また、スリット６ａ〜６ｄ、１０ａ〜１０ｄによって剛性が低下し易い円筒壁１１を仕切り壁１２で支持して剛性向上を図ることができ、これにより、円筒壁１１と仕切り壁１２を従来の厚みと同じまたはそれ以下にしつつ、亀裂・破損を防止できる。   Further, the cylindrical wall 11 whose rigidity is likely to be lowered by the slits 6a to 6d and 10a to 10d can be supported by the partition wall 12 to improve the rigidity, and thereby the cylindrical wall 11 and the partition wall 12 can be made to have the conventional thickness. Cracks and breakage can be prevented while keeping the same or lower.

さらに、室１３ａの冷却水は、スリット６ｂ〜６ｄ、１０ｂ〜１０ｄを介して各室１３ｃ〜１３ｅに同時に流入するため、気液混合の冷却水を連鎖連通ではなく同時連通させて効率よく気液分離させることができ、気液分離性能をさらに向上させることができる。   Further, since the cooling water in the chamber 13a simultaneously flows into the chambers 13c to 13e via the slits 6b to 6d, 10b to 10d, the gas-liquid mixed cooling water is connected simultaneously instead of chained and efficiently. The gas-liquid separation performance can be further improved.

次に、効果を説明する。
以上、説明したように、本実施例１の加圧式リザーブタンクにあっては、タンク本体Ａの内部を、中央に配置され、且つ、略円筒状に形成された円筒壁１１と、この円筒壁１１から外側へ放射状に伸びる仕切り壁１２で複数の室１３ａ〜１３ｅに区画し、円筒壁１１に、該円筒壁内１１の室１３ａと隣接する室１３ｂ〜１３ｅを連通状態にするスリット６ａ〜６ｄ、１０ａ〜１０ｄを設けたため、内圧による応力集中を無くすことができると同時に、気液分離性能を向上できる。 Next, the effect will be described.
As described above, in the pressurization type reserve tank of the first embodiment, the inside of the tank main body A is disposed in the center and the cylindrical wall 11 is formed in a substantially cylindrical shape, and the cylindrical wall. A partition wall 12 radially extending from 11 to the outside is partitioned into a plurality of chambers 13a to 13e, and slits 6a to 6d are connected to the cylindrical wall 11 so that the chambers 13b to 13e adjacent to the chamber 13a in the cylindrical wall 11 communicate with each other. Since 10a to 10d are provided, stress concentration due to internal pressure can be eliminated, and at the same time gas-liquid separation performance can be improved.

以上、本実施例を説明してきたが、本発明は上述の実施例に限られるものではなく、本発明の要旨を逸脱しない範囲の設計変更等があっても、本発明に含まれる。
例えば、タンク本体Ａの内部を区画する区画数については適宜設定でき、同様に、スリットの形状、形成数、形成位置についても適宜設定できる。
また、円筒壁１１を例えば、６角形状、または８角形状等に形成することは当然考えられるが、角を形成すると応力がこの部位に集中し易いため、あまり好ましくない。 Although the present embodiment has been described above, the present invention is not limited to the above-described embodiment, and design changes and the like within the scope not departing from the gist of the present invention are included in the present invention.
For example, the number of compartments that divide the inside of the tank main body A can be set as appropriate, and similarly, the shape, number of formations, and formation positions of the slits can be set as appropriate.
In addition, it is naturally conceivable to form the cylindrical wall 11 in, for example, a hexagonal shape, an octagonal shape, or the like. However, forming a corner is not preferable because stress tends to concentrate on this portion.
