本考案は、高温のオイルを通す円筒を冷媒中で回転させ
オイルを冷却するようにした回転式オイルクーラに関す
る。[Detailed Description of the Invention] The present invention relates to a rotary oil cooler in which a cylinder through which hot oil passes is rotated in a refrigerant to cool the oil.
従来、エンジンに付設されるオイルクーラには、エンジ
ンのラジェータタンク内に二重管式の熱交換器を設置し
、高温オイルを該熱交換器に通し、二重管の内外からエ
ンジン冷却水によりオイルを冷却するようにした静止型
のものが多かった。Conventionally, oil coolers attached to engines have a double-tube heat exchanger installed inside the engine's radiator tank, and high-temperature oil is passed through the heat exchanger, and engine cooling water is supplied from the inside and outside of the double-tube. Many were stationary types that cooled the oil.
しかしながら小さなラジェータタンク内にオイル用熱交
換器を設置することは設計上、製作上窮屈であり、充分
な性能を持つオイルクーラを作ることは困難であった。However, installing an oil heat exchanger inside a small radiator tank is difficult in terms of design and manufacturing, and it has been difficult to create an oil cooler with sufficient performance.
またオイルクーラをラジェータの外に設けると、冷却水
を流動させるために別にポンプが必要となり、経済的に
得策でない。Furthermore, if the oil cooler is provided outside the radiator, a separate pump will be required to flow the cooling water, which is not economically advisable.
本考案は、このような従来のオイルクーラの欠点を除い
た有効なオイルクーラを得ることを目的とした考案であ
って、オイルクーラをエンジン用ラジェータの外に設け
、しかも冷媒はオイルの動圧を利用したオイルクーラ自
体の回転により流動させるという新規な構造の回転式オ
イルクーラを得たものである。The present invention aims to provide an effective oil cooler that eliminates the drawbacks of conventional oil coolers, and the oil cooler is installed outside the engine radiator, and the refrigerant is controlled by the dynamic pressure of the oil. This is a rotary oil cooler with a novel structure in which fluid is caused by the rotation of the oil cooler itself.
以下図示の実施例について説明する。The illustrated embodiment will be described below.
第１図は回転式オイルクーラの第一実施例の縦断側面図
であって、回転円筒１の両端を絞り直径を小さくして軸
受２を結合し、外筒３に水密に取付けたオイルの入口管
４、出口管５に回転自在に嵌合させている。FIG. 1 is a longitudinal sectional side view of a first embodiment of a rotary oil cooler, in which both ends of a rotating cylinder 1 are narrowed to reduce its diameter, a bearing 2 is connected thereto, and an oil inlet is watertightly attached to an outer cylinder 3. It is rotatably fitted into the pipe 4 and outlet pipe 5.
６は外筒３と多管４，５とを水密に結合すると共に軸受
２と摺接して推力を受ける軸受である。Reference numeral 6 denotes a bearing that connects the outer cylinder 3 and the multi-tubes 4 and 5 in a watertight manner, and also receives thrust by slidingly contacting the bearing 2.
回転円筒１の内面には螺旋羽根７の外周を固定し、螺旋
羽根７の内周には中子８を固定する。The outer periphery of a spiral blade 7 is fixed to the inner surface of the rotating cylinder 1, and the core 8 is fixed to the inner periphery of the spiral blade 7.
回転円筒１の外面には羽根板９を点在させて取付ける。Wing plates 9 are attached to the outer surface of the rotating cylinder 1 in a scattered manner.
この羽根板９には回転円筒１の回転により外筒３内の冷
却液を入口１０から出口１１に向けて流動させるように
迎え角を付しておく。The vane plate 9 is provided with an angle of attack so that the rotation of the rotary cylinder 1 causes the coolant in the outer cylinder 3 to flow from the inlet 10 to the outlet 11.
以上のように構成されるから、ポンプにより圧送される
高温のオイルを入口管４から回転円筒１内へ流入させる
と、オイルは円筒１の内面と中子８との間を通って出口
管５へ流出するが、その間に螺旋羽根７を押して円筒１
を回転させる。With the above structure, when high-temperature oil pumped by the pump flows into the rotating cylinder 1 from the inlet pipe 4, the oil passes between the inner surface of the cylinder 1 and the core 8 and flows into the outlet pipe 5. During this time, the spiral blade 7 is pushed and the cylinder 1 is
Rotate.
これにより円筒１の外面に取付けた迎え角を持つ羽根板
９が円筒１と外筒３との間に充満した冷却液中で回転し
、冷却液を入口１０から出口１１に向けて流動させる。As a result, the vane plate 9 attached to the outer surface of the cylinder 1 and having an angle of attack rotates in the coolant filled between the cylinder 1 and the outer cylinder 3, causing the coolant to flow from the inlet 10 to the outlet 11.
このように回転円筒１を回転させつつ螺旋羽根７に沿っ
てオイルが流動する間に、オイルの持つ熱は円筒１およ
び羽根板９に伝わり、該円筒１および羽根板９の外面か
ら冷却液中に放散され、オイルは冷却されて出口管５か
ら流出する。While the rotating cylinder 1 is rotated and the oil flows along the spiral blades 7, the heat of the oil is transmitted to the cylinder 1 and the blade plate 9, and is transferred from the outer surface of the cylinder 1 and the blade plate 9 into the cooling liquid. The oil is cooled and flows out from the outlet pipe 5.
即ち螺旋羽根７および羽根板９は伝熱用フィンの役目も
している。That is, the spiral blades 7 and the blade plates 9 also serve as heat transfer fins.
第２図は回転円筒１の軸受部分の構造を変更した第二実
施例を示し、入口管４、出口管５を軸受２を介して回転
円筒１に油密に固定し、容管４゜５を軸受６で回転自在
に支持し、円筒１と共に回転する管４，５にはロータリ
ジヨイント１２，１３を介して送油するようにしたもの
である。FIG. 2 shows a second embodiment in which the structure of the bearing part of the rotating cylinder 1 is changed, and the inlet pipe 4 and the outlet pipe 5 are oil-tightly fixed to the rotating cylinder 1 via the bearing 2, and the container pipe 4°5 is rotatably supported by a bearing 6, and oil is supplied to tubes 4 and 5 rotating together with the cylinder 1 via rotary joints 12 and 13.
第一実施例の構造では軸受２の部分で油が漏ると冷却液
中の混入するため漏油防止に考慮を払わなければならな
いが、第二実施例ではこの心配はない。In the structure of the first embodiment, if oil leaks from the bearing 2, it will mix in the coolant, so consideration must be given to preventing oil leakage, but in the second embodiment, this is not a concern.
その他の構造は第一実施例と同様であり、熱交換作用も
同様である。The rest of the structure is the same as that of the first embodiment, and the heat exchange function is also the same.
本考案のオイルクーラは、上記実施例で判るように、ポ
ンプにより圧送される高温オイルを回転円筒１と中子８
との間に形成される狭い通路を通すことによってオイル
の持つ熱を円筒１、羽根板９に伝えるものであるから、
伝熱効率がよく、これと共に回転円筒１に回転運動を起
させ、冷却液をも流動させるものであるから、冷却水循
還ポンプや駆動用動力装置が不要である。As can be seen from the above embodiment, the oil cooler of the present invention pumps high-temperature oil between the rotating cylinder 1 and the core 8.
The heat of the oil is transmitted to the cylinder 1 and the blade plate 9 by passing through a narrow passage formed between the cylinder 1 and the blade plate 9.
Since the heat transfer efficiency is good and the rotary cylinder 1 is caused to rotate and the coolant is also caused to flow, a coolant circulation pump or a driving power device is not required.
特に本考案は、紡錘形の中子８を螺旋羽根７を介して回
転円筒１の中心部に保持し、回転円筒１の両端部を中子
８の形状に倣って次第に細くしたから、入口管４から回

に誘導され、その結果、回転円筒壁を通しての伝熱、即
ち冷却が良好に行なわれ、また円筒１を回転させるトル
クを大きくすることができる。In particular, in the present invention, the spindle-shaped core 8 is held in the center of the rotating cylinder 1 via the spiral blade 7, and both ends of the rotating cylinder 1 are tapered gradually following the shape of the core 8, so that the inlet pipe 4 The oil flowing into the rotating cylinder 1 is guided near the inner surface of the rotating cylinder 1, and as a result, heat transfer through the rotating cylinder wall, that is, cooling is performed well, and the torque for rotating the cylinder 1 is increased. be able to.
この作用はエンジンの回転速度の変化によって変り、エ
ンジンの回転速度が大でオイルの温度上昇が大きくなる
に従って冷却の程度を大きくし、常にエンジンの運転状
態に適応したオイル冷却が行なえる。This effect changes depending on changes in the engine rotational speed, and as the engine rotational speed increases and the temperature rise of the oil increases, the degree of cooling increases, and oil cooling can always be performed in accordance with the operating conditions of the engine.
またエンジンラジェータとは別個に設置されるものであ
るから、設置空間、大きさ、形状の制約が緩やかになり
、回転円筒の径を充分大きくして伝熱面積を増したり、
螺旋羽根７、羽根板９の大きさ、数等を自由に選択して
効率のよい冷却を行なうことができるものである。In addition, since it is installed separately from the engine radiator, there are fewer restrictions on installation space, size, and shape, and the diameter of the rotating cylinder can be made sufficiently large to increase the heat transfer area.
Efficient cooling can be achieved by freely selecting the size, number, etc. of the spiral blades 7 and blade plates 9.
なお、上記実施例には冷却液を使用するものを示したが
、羽根板９を大きくして空冷型として構成することも可
能である。Although the above embodiment uses a cooling liquid, it is also possible to make the blade plate 9 larger and configure it as an air-cooled type.
この場合は外筒３を省いて大気中で回転円筒１を回転さ
せるようにすることもできる。In this case, the outer cylinder 3 may be omitted and the rotary cylinder 1 may be rotated in the atmosphere.
また螺旋羽根７、羽根板９は、状況に応じて連続させた
り断続させたりすることができるものである。Further, the spiral blades 7 and the blade plates 9 can be made continuous or intermittent depending on the situation.
