And the second core portion are connected in series via an intermediate tank, and the intermediate tank is provided with a cooling water outlet.

そして、好ましくは、前記中間タンクには、その内部を前記第１コア部側と前記第２コア部側とに分割するように仕切部が形成されており、前記第１コア部のチューブから前記中間タンクに流入した冷却水と、前記第２コア部のチューブから前記中間タンクに流入した冷却水とがそれぞれ、直接、干渉し合わないように構成されているのがよい。   Preferably, the intermediate tank is formed with a partition portion so as to divide the inside thereof into the first core portion side and the second core portion side, and the tube from the first core portion is It is preferable that the cooling water flowing into the intermediate tank and the cooling water flowing into the intermediate tank from the tube of the second core portion are not directly interfered with each other.

さらに、前記冷却水出口は、通水断面積が前記第１コア部のチューブと前記第２コア部のチューブの合計通水断面積より大きくなるように形成されているのがよい。   Furthermore, the cooling water outlet may be formed so that a water flow cross-sectional area is larger than a total water flow cross-sectional area of the tube of the first core part and the tube of the second core part.

本発明によれば、冷却水の圧力損失を低減し、冷却水の流量を十分に確保することができるため、放熱性能の向上を図ることのできる等、種々の優れた効果を得ることができる。   According to the present invention, the pressure loss of the cooling water can be reduced and the flow rate of the cooling water can be sufficiently secured, so that various excellent effects can be obtained, such as the improvement of the heat dissipation performance. .

以下、図１を参照しつつ、本発明の実施の形態について説明する。ここで、図１は本実施の形態に係るクロスフロー型ラジエータを示す正面図である。   Hereinafter, an embodiment of the present invention will be described with reference to FIG. Here, FIG. 1 is a front view showing a cross-flow radiator according to the present embodiment.

このクロスフロー型ラジエータ１１は、コア１２と、コア１２の左右両側にそれぞれ鉛直姿勢で設けられた入口側タンク１３，１４とが一体ろう付けにより固定されて構成されており、入口側タンク１３，１４の上部にはそれぞれ冷却水入口１５，１６が設けられている。   The cross-flow radiator 11 is configured by fixing a core 12 and inlet side tanks 13 and 14 provided in a vertical posture on both the left and right sides of the core 12 by integral brazing. Cooling water inlets 15 and 16 are provided in the upper part of 14 respectively.

コア１２は、第１コア部１７と第２コア部１８とに分割されており、第１コア部１７と第２コア部１８は鉛直に設けられた中間タンク１９を介して直列に接続されている。また、第１コア部１７及び第２コア部１８は、それぞれ、水平に並設された複数のチューブ２０，２１と各チューブ２０，２１の周りに設けられたフィン２２，２３とから構成され、第１コア部１７及ぶ第２コア部１８の上下にはそれぞれ補強プレート２４，２５が設けられている。   The core 12 is divided into a first core part 17 and a second core part 18, and the first core part 17 and the second core part 18 are connected in series via an intermediate tank 19 provided vertically. Yes. The first core portion 17 and the second core portion 18 are each composed of a plurality of tubes 20 and 21 horizontally arranged and fins 22 and 23 provided around the tubes 20 and 21, respectively. Reinforcing plates 24 and 25 are provided above and below the first core portion 17 and the second core portion 18, respectively.

中間タンク１９には、その内部を第１コア部１７側と第２コア部１８側とに分割するように鉛直に仕切部２６が形成されており、第１コア部１７のチューブ２０から中間タンク１９に流入した冷却水と、第２コア部１８のチューブ２１から中間タンク１９に流入した冷却水とがそれぞれ、直接、干渉し合わないようになっている。また、中間タンク１９には、下端に冷却水出口２７が設けられており、冷却水出口２７の通水断面積は第１コア部１７のチューブ２０と第２コア部１８のチューブ２１の合計通水断面積より大きくなっている。   In the intermediate tank 19, a partition part 26 is vertically formed so as to divide the inside into the first core part 17 side and the second core part 18 side, and the intermediate tank 19 extends from the tube 20 of the first core part 17. The cooling water that has flowed into 19 and the cooling water that has flowed into the intermediate tank 19 from the tube 21 of the second core portion 18 do not directly interfere with each other. The intermediate tank 19 is provided with a cooling water outlet 27 at the lower end, and the cross-sectional area of the cooling water outlet 27 is the total passage of the tube 20 of the first core portion 17 and the tube 21 of the second core portion 18. It is larger than the water cross section.

次に、本実施の形態に係るクロスフロー型ラジエータ１１の作用について説明する。   Next, the operation of the crossflow radiator 11 according to the present embodiment will be described.

冷却水は、左右の各冷却水入口１５，１６から入口側タンク１３，１４を通り、第１コア部１７の各チューブ２０内及び第２コア部１８の各チューブ２１内に流入する。そして、この冷却水は、各チューブ２０，２１内を流通する間、チューブ２０，２１の外面及び各フィン２２，２３に接触する空気により冷却された後、中間タンク１９に流入する。この場合、コア１２が第１コア部１７と第２コア部１８の２つに分割されており、それぞれのチューブ２０，２１の長さが短縮されているため、各チューブ２０，２１を流通する際の冷却水の圧力損失を低く抑制することができる。したがって、各チューブ２０，２１において冷却水の流量を十分に確保することができ、各コア部１７，１８における放熱性能を高めることができる。   The cooling water flows from the left and right cooling water inlets 15, 16 through the inlet side tanks 13, 14 into the tubes 20 of the first core part 17 and the tubes 21 of the second core part 18. And while this cooling water distribute | circulates in each tube 20 and 21, after cooling with the air which contacts the outer surface of the tubes 20 and 21 and each fin 22 and 23, it flows in into the intermediate tank 19. FIG. In this case, the core 12 is divided into two parts, the first core part 17 and the second core part 18, and the lengths of the respective tubes 20, 21 are shortened. The pressure loss of the cooling water at the time can be suppressed low. Therefore, the flow rate of the cooling water can be sufficiently secured in each of the tubes 20 and 21, and the heat radiation performance in each of the core portions 17 and 18 can be enhanced.

そして、第１コア部１７のチューブ２０から中間タンク１９に流入した冷却水と、第２コア部１８のチューブ２１から中間タンク１９に流入した冷却水とはそれぞれ、仕切部２６に衝突し、下方に向かって流通し、冷却水出口２７からエンジンに還流される。すなわち、仕切部２６により、第１コア部１７側から中間タンク１９に流入した冷却水と、第２コア部１８側から中間タンク１９に流入した冷却水とが、それぞれ、直接、干渉し合わないようになっているため、中間タンク１９内において冷却水の流れは整流化され、冷却水の圧力損失を低く抑制することができる。また、冷却水出口２７は、その通水断面積が第１コア部１７のチューブ２０と第２コア部１８のチューブ２１の合計通水断面積より大きくなるように形成されているため、冷却水出口２７における冷却水の圧力損失も低く抑制することができる。   And the cooling water which flowed into the intermediate tank 19 from the tube 20 of the 1st core part 17, and the cooling water which flowed into the intermediate tank 19 from the tube 21 of the 2nd core part 18 collide with the partition part 26, respectively, And flows back to the engine from the cooling water outlet 27. In other words, the cooling water that has flowed into the intermediate tank 19 from the first core portion 17 side and the cooling water that has flowed into the intermediate tank 19 from the second core portion 18 side do not directly interfere with each other by the partition portion 26. Therefore, the flow of the cooling water is rectified in the intermediate tank 19, and the pressure loss of the cooling water can be suppressed low. Moreover, since the cooling water outlet 27 is formed so that the water flow cross-sectional area is larger than the total water flow cross-sectional area of the tube 20 of the first core portion 17 and the tube 21 of the second core portion 18, The pressure loss of the cooling water at the outlet 27 can also be suppressed low.

このように、上記したクロスフロー型ラジエータ１１によれば、チューブ２０，２１、中間タンク１９、及び冷却水出口２７において、それぞれ、冷却水の圧力損失を低減させることができるため、システム全体の効率を向上させることができる。   Thus, according to the cross flow type radiator 11 described above, the pressure loss of the cooling water can be reduced at the tubes 20 and 21, the intermediate tank 19, and the cooling water outlet 27, respectively. Can be improved.

なお、上記したクロスフロー型ラジエータ１１において、中間タンク１９をコア１２の中心に配置し、第１コア部１７と第２コア部１８が左右対称形状となるように構成させる他、コア部における空気の風抜け性を考慮して、第１コア部１７と第２コア部１８とで、各コア部の厚みやチューブ２０，２１及びフィン２２，２３の間隔又は長さを変えたりする等、各種変更が可能である。   In the cross-flow type radiator 11 described above, the intermediate tank 19 is disposed at the center of the core 12 and the first core portion 17 and the second core portion 18 are configured to have a bilaterally symmetrical shape. In consideration of the air draft of the first core portion 17 and the second core portion 18, various thicknesses such as changing the thickness of each core portion and the interval or length of the tubes 20 and 21 and the fins 22 and 23 are various. It can be changed.
