(57) [Summary] [Purpose] To provide an engine-lubricating-oil water-cooled oil cooler with excellent heat exchange efficiency with little pressure loss due to changes in the direction of lubricating oil and cooling water flow. [Configuration] A lubricating oil water-cooled oil cooler 1 is formed in a spiral shape in which lubricating oil passages 2 to 2 and cooling water passages 3 to 3 are alternately in contact with each other in the vertical direction.

Description
【０００１】[0001]
この考案は、エンジン潤滑油水冷式オイルクーラーに関する。 This invention relates to an engine lubricating oil water-cooled oil cooler.
【０００２】[0002]
従来のエンジン潤滑油水冷式オイルクーラーを図３を参照して説明すると、オ イルクーラー１０は円筒状に形成され、その内部には環状の冷却水室１１〜１１ と同様に環状の潤滑油室１２〜１２が上下方向に交互に形成され、潤滑油室１２ 〜１２は相互間を上下方向の連通管を介して連結されている。 A conventional engine lubricating oil water-cooling type oil cooler will be described with reference to FIG. 3. The oil cooler 10 is formed in a cylindrical shape, and an annular lubricating oil chamber is formed therein as in the annular cooling water chambers 11 to 11. 12 to 12 are formed alternately in the vertical direction, and the lubricating oil chambers 12 to 12 are connected to each other via a communication pipe in the vertical direction.
【０００３】[0003]
ところで、このような潤滑油水冷式オイルクーラーでは、潤滑油は潤滑油室１ ２を円周方向に流れた後、次段の潤滑油室１２に上下方向の連通管を介して流入 する構成であり、このため連通管部位で流れの方向が変わって淀みが生じること となっていた。このような流れの方向の変化は冷却水室１１〜１１間においても 同様であり、このため熱交換効率が低下するとともに、圧力損失が大きい欠点を 有していた。 By the way, in such a lubricating oil water-cooled oil cooler, after the lubricating oil flows in the lubricating oil chamber 12 in the circumferential direction, the lubricating oil flows into the lubricating oil chamber 12 of the next stage through the communication pipe in the vertical direction. As a result, the flow direction changed at the connecting pipe, causing stagnation. Such a change in the direction of the flow is the same between the cooling water chambers 11 to 11, so that the heat exchange efficiency is reduced and the pressure loss is large.

上記課題を解決するため、本考案の潤滑油水冷式オイルクーラーは潤滑油通路 と冷却水通路とをそれぞれが互いに上下方向で交互に接触する螺旋状に形成して 構成される。 In order to solve the above problems, the lubricating oil / water cooling type oil cooler of the present invention is configured by forming a lubricating oil passage and a cooling water passage in a spiral shape that are alternately in contact with each other in the vertical direction.
【０００５】[0005]
本考案の潤滑油水冷式オイルクーラーでは、潤滑油及び冷却水はそれぞれ螺旋 状の潤滑油通路と冷却水通路を通って、入口から出口に至り、急激な方向変換を 伴うことなく円滑に流れることができる。 In the lubricating oil water-cooled oil cooler of the present invention, the lubricating oil and the cooling water flow smoothly from the inlet to the outlet through the spiral lubricating oil passage and the cooling water passage, respectively, without sudden direction change. You can
【０００６】[0006]
次に本考案の実施例を図１及び図２を参照して説明する。 図１に縦断面で示した潤滑油水冷式オイルクーラー１（以下単にオイルクーラ ー１という）は相互に螺旋状に連続する冷却水通路２〜２と、同様に相互に螺旋 状に連続する潤滑油通路３〜３とを、二重螺旋状に重ね合わせ、最上段及び最下 段のものを除き、各冷却水通路２が潤滑油通路３と上下に隣接するように、また 、逆に言うと各潤滑油通路３が冷却水通路２と上下に隣接するように配置して構 成されており、中央部にはオイルクーラー１を固定するためのボルト（図示しな い）を挿通するための穴４が形成されている。 Next, an embodiment of the present invention will be described with reference to FIGS. A lubricating oil water-cooled oil cooler 1 (hereinafter simply referred to as an oil cooler 1) shown in a longitudinal section in FIG. The oil passages 3 to 3 are overlapped with each other in a double spiral shape, and each cooling water passage 2 is vertically adjacent to the lubricating oil passage 3 except for the uppermost and lowermost ones, and vice versa. And each lubricating oil passage 3 are arranged vertically adjacent to the cooling water passage 2, and a bolt (not shown) for fixing the oil cooler 1 is inserted in the central portion. Hole 4 is formed.
【０００７】 オイルクーラー１の下面には最下段の潤滑油通路３に連通する潤滑油入口５が 設けられており、また、中央部の穴４の上部には最上段の潤滑油通路３に連通す る潤滑油出口６、６が形成され、図示しないエンジンから潤滑油入口５に導かれ た潤滑油は潤滑油通路３〜３を上下方向に螺旋状に流れて潤滑油出口６、６を経 て再びエンジンに戻される。なお、潤滑油出口６、６を出た潤滑油は上記ボルト に設けた通路を通ってエンジンに導かれるものである。A lubricating oil inlet 5 communicating with the lowermost lubricating oil passage 3 is provided on the lower surface of the oil cooler 1, and a lubricating oil inlet 5 communicating with the uppermost lubricating oil passage 3 is provided above the central hole 4. Lubricating oil outlets 6 and 6 are formed. The lubricating oil introduced from the engine (not shown) to the lubricating oil inlet 5 flows vertically through the lubricating oil passages 3 to 3 and passes through the lubricating oil outlets 6 and 6. And is returned to the engine again. The lubricating oil exiting the lubricating oil outlets 6, 6 is guided to the engine through the passage provided in the bolt.
【０００８】 一方、オイルクーラー１の下部外周、及び上面には、最下段の冷却水通路２及 び最上段の冷却水通路２にそれぞれ連続するコネクタ７及び８が接続されており 、図示しないラジエターの低温側から導かれた冷却水はこれらのコネクタ７及び ８のいずれかを一方を入口として冷却水通路２〜２を螺旋状に流れ、コネクタ７ 及び８の他方から流出するようになっている。On the other hand, the lower outer circumference and the upper surface of the oil cooler 1 are connected to the cooling water passage 2 at the lowermost stage and the connectors 7 and 8 continuous to the cooling water passage 2 at the uppermost stage, respectively. The cooling water introduced from the low temperature side of the connector spirally flows through the cooling water passages 2 to 2 with one of the connectors 7 and 8 as an inlet and flows out from the other of the connectors 7 and 8. .
【０００９】 次に、上記の冷却水通路２〜２と潤滑油通路３〜３を相互に隔てる螺旋状の隔 壁は図２に示した隔壁部材９を複数連結することにより形成されており、隔壁部 材９は同図２に示すように螺旋の一部をなし、一端９ａから他端９ｂに至り徐々 に上方に傾斜した略扇形の形状に形成されている。他端９ｂには上段に位置する 同様な隔壁部材９の一端９ａとの連結部９ｃが段状に形成されており、この連結 部９ｃを介して隔壁部材９〜９を順次連結することで、連続する螺旋状の隔壁を 形成することができるものである。Next, the spiral partition wall that separates the cooling water passages 2-2 and the lubricating oil passages 3-3 from each other is formed by connecting a plurality of partition wall members 9 shown in FIG. The partition wall member 9 forms a part of a spiral as shown in FIG. 2, and is formed in a substantially fan shape that gradually inclines upward from one end 9a to the other end 9b. On the other end 9b, a connecting portion 9c with the one end 9a of the similar partition member 9 located on the upper stage is formed in a stepped shape, and by sequentially connecting the partition members 9 to 9 through this connecting portion 9c, It is possible to form a continuous spiral partition wall.
【００１０】 本実施例のオイルクーラー１では、冷却水通路２〜２と潤滑油通路３〜３とは いずれも螺旋状に形成されており、冷却水はコネクタ７から８その逆向きに螺旋 状に流れ、また潤滑油も潤滑油入口５から潤滑油出口６、６に至り螺旋状に流れ 、いずれも急激な方向変換を伴わない円滑な流れが得られるものである。従って 、冷却水及び潤滑油の圧力損失が少なくなり、熱交換効率が向上して冷却能力が 向上する利点を有する。In the oil cooler 1 of the present embodiment, the cooling water passages 2 to 2 and the lubricating oil passages 3 to 3 are both formed in a spiral shape, and the cooling water is formed in a spiral shape in the opposite direction from the connectors 7 to 8. In addition, the lubricating oil flows from the lubricating oil inlet 5 to the lubricating oil outlets 6, 6 in a spiral shape, and a smooth flow is obtained without any sudden direction change. Therefore, there is an advantage that the pressure loss of the cooling water and the lubricating oil is reduced, the heat exchange efficiency is improved, and the cooling capacity is improved.
