この発明は、リザーバタンクからオーバーフローした冷却水を、ラジエータファンを通過する通過風によって周囲に飛散させることなく、車両下方へ排出する目的を、排出ロから縦壁部側に延びた後、縦壁部に沿って鉛直方向に延びる凹溝をリザーバタンクの上面と前面とにわたって形成して実現するものである。   The present invention aims to discharge the cooling water overflowed from the reservoir tank to the lower side of the vehicle without being scattered around by the passing air passing through the radiator fan. A concave groove extending in the vertical direction along the portion is formed across the upper surface and the front surface of the reservoir tank.

図１〜図６は、この発明の実施例を示すものである。
図１〜図３において、１は車両前部でエンジンの前方に搭載されるラジエータである。
このラジエータ１は、中央部のラジエータ本体２と、このラジエータ本体２の上部に連設した上側タンク３と、ラジエータ本体２の下部に連設した下側タンク４とが一体的になって構成される。
このラジエータ１の本体２の後部には、ファンシュラウド５が取り付けられる。
このファンシュラウド５は、ラジエータファン６の全周を覆って通過風を車両後方に案内する円筒部７と、この円筒部７の径方向外側に拡がってラジエータ１の後部に取り付けられる縦壁部８とを有する。
ラジエータ１の円筒部７の上側かつ縦壁部８の後部には、エンジンの冷却水を貯留するリザーバタンク９が取り付けられるとともに、このリザーバタンク９の冷却水排出装置１０が設けられる。
この冷却水排出装置１０は、リザーバタンク９からオーバーフローした冷却水を外部に排出する排出口１１をリザーバタンク９の上部に備えている。
また、冷却水排出装置１０においては、図３、図６に示すように、排出口１１から縦壁部８側に延びた後、縦壁部８に沿って鉛直方向に延びる凹溝１２が、リザーバタンク９の上面１３と前面１４とにわたって、上面側凹溝１２Ａと前面側凹溝１２Ｂとして形成される。 1 to 6 show an embodiment of the present invention.
1 to 3, reference numeral 1 denotes a radiator mounted in front of the engine at the front of the vehicle.
The radiator 1 includes a central radiator body 2, an upper tank 3 connected to the upper portion of the radiator body 2, and a lower tank 4 connected to the lower portion of the radiator body 2. The
A fan shroud 5 is attached to the rear portion of the main body 2 of the radiator 1.
The fan shroud 5 includes a cylindrical portion 7 that covers the entire circumference of the radiator fan 6 and guides the passing air to the rear of the vehicle, and a vertical wall portion 8 that extends outward in the radial direction of the cylindrical portion 7 and is attached to the rear portion of the radiator 1. And have.
A reservoir tank 9 for storing engine cooling water is attached to an upper side of the cylindrical portion 7 of the radiator 1 and a rear portion of the vertical wall portion 8, and a cooling water discharge device 10 for the reservoir tank 9 is provided.
The cooling water discharge device 10 includes a discharge port 11 for discharging the cooling water overflowed from the reservoir tank 9 to the outside at the upper part of the reservoir tank 9.
Further, in the cooling water discharge device 10, as shown in FIGS. 3 and 6, the groove 12 extending in the vertical direction along the vertical wall portion 8 after extending from the discharge port 11 to the vertical wall portion 8 side, Over the upper surface 13 and the front surface 14 of the reservoir tank 9, it is formed as an upper surface side concave groove 12A and a front surface side concave groove 12B.

このような構造により、排出口１１からオーバーフローした冷却水（図面上の白抜きの矢印Ｗで示す）を、ファンシュラウド５の縦壁部８側に流出させることができ、ラジエータファン６を通過する通過風から冷却水を遠ざけることができる。
また、リザーバタンク９には縦壁部８に沿って鉛直方向に延びる凹溝１２を形成したことで、排出口１１からオーバーフローした冷却水を、凹溝１２に沿って流すことができ、縦壁部８と凹溝１２とで、この冷却水が、ラジエータファン６の前方側に流れ込んだり、大きく進路を外れたりすることを防止でき、また、ラジエータファン６を通過した通過風に晒されて飛散されることなく、車両下方へと落下することができる。
これによって、ラジエータファン６を通過する通過風にリザーバタンク９からオーバーフローした冷却水が晒されることがなくなり、リザーバタンク９の周囲に冷却水が飛散するのを防止できる。 With such a structure, the cooling water overflowed from the discharge port 11 (indicated by a white arrow W in the drawing) can be discharged to the vertical wall portion 8 side of the fan shroud 5 and passes through the radiator fan 6. Cooling water can be kept away from passing air.
Further, since the reservoir tank 9 is formed with the concave groove 12 extending in the vertical direction along the vertical wall portion 8, the cooling water overflowed from the discharge port 11 can flow along the concave groove 12. The cooling water can be prevented from flowing into the front side of the radiator fan 6 or greatly deviating from the course by the portion 8 and the concave groove 12, and is also scattered by being exposed to the passing air passing through the radiator fan 6. It can fall to the vehicle lower part without being done.
Accordingly, the cooling water overflowed from the reservoir tank 9 is not exposed to the passing air passing through the radiator fan 6, and the cooling water can be prevented from scattering around the reservoir tank 9.

また、図１、図５に示すように、リザーバタンク９の底面１５は、円筒部７の一部に沿って湾曲状に形成され、円筒部７に対して所定の隙間Ｓを隔てた状態で対向する。また、円筒部７には、リザーバタンク９の底面１５側に突出して冷却水を円筒部７の周方向に導く遮蔽壁１６を形成する。
このような構造では、遮蔽壁１６によって、リザーバタンク９の底面１５と円筒部７との間に形成される隙間Ｓを遮蔽できる。
これによって、凹溝１２を通過して円筒部７に流れてきた冷却水を隙間Ｓからラジエータファン６側へ流れ出るのを防止でき、冷却水を円筒部７の周方向に導くことができ、ラジエータファン６を通過した通過風から冷却水を遠ざけることができる。 Further, as shown in FIGS. 1 and 5, the bottom surface 15 of the reservoir tank 9 is formed in a curved shape along a part of the cylindrical portion 7, with a predetermined gap S from the cylindrical portion 7. opposite. The cylindrical portion 7 is formed with a shielding wall 16 that protrudes toward the bottom surface 15 of the reservoir tank 9 and guides the cooling water in the circumferential direction of the cylindrical portion 7.
In such a structure, the gap S formed between the bottom surface 15 of the reservoir tank 9 and the cylindrical portion 7 can be shielded by the shielding wall 16.
Accordingly, it is possible to prevent the cooling water flowing through the concave groove 12 and flowing into the cylindrical portion 7 from flowing out from the gap S toward the radiator fan 6, and to guide the cooling water in the circumferential direction of the cylindrical portion 7. The cooling water can be kept away from the passing air that has passed through the fan 6.

更に、図１、図２、図５に示すように、ファンシュラウド５には、リザーバタンク９を取り付ける取付部１７を形成し、そして、この取付部１７を遮蔽壁１６に連結する。
このような構造では、取付部１７によって遮蔽壁１６の剛性を高めることができ、車両の振動による遮蔽壁１６の変形や撓みを抑制できる。
これによって、リザーバタンク９と円筒部７の間を遮蔽壁１６によって気密にでき、遮蔽壁１６で冷却水がラジエータファン６側に流れ出るのを確実に防止できる。 Further, as shown in FIGS. 1, 2, and 5, the fan shroud 5 is formed with an attachment portion 17 for attaching the reservoir tank 9, and the attachment portion 17 is connected to the shielding wall 16.
In such a structure, the rigidity of the shielding wall 16 can be increased by the mounting portion 17, and deformation and bending of the shielding wall 16 due to vibration of the vehicle can be suppressed.
Thus, between the reservoir tank 9 and the cylindrical portion 7 can airtightly by the shielding wall 16, cooling water can be reliably prevented from flowing to the radiator fan 6 side shielding wall 16.
