SOLUTION: In a heat exchanger in which an opening 4 is formed in the hood 3 of a part where an air scoop 2 is positioned and an inter-cooler 5 being a heat exchanger is arranged below the opening 4, the inter-cooler 5 is arranged in a direction approximately in parallel with a hood surface, and thickness T1 on a vehicle front side is formed thicker than thickness T2 on a rear side. Also, fins 6 arranged between a plurality of tubes 11 by which an inlet side tank 9 and an outlet side tank 10 are connected to each other, are inclined in an opposite direction on the vehicle front side and the rear side, and formed into an approximately opened angle shape. Further, fin pitches being intervals among the fins 6 are finely set according as they approach the rear side. Hereby, the cooling wind passing amount of the inter-cooler 5 can be uniformalized.

In this figure, an opening 4 is provided in a bonnet 3 at a position where the air scoop 2 is located, and an intercooler 5 as a heat exchanger is provided on an engine (not shown) located below the hood. ing. The intercooler 5
Is disposed substantially parallel to the hood surface, and the thickness T 1 of the front side of the vehicle is thicker than the thickness T 2 of the rear side.
The fins 6 are inclined in opposite directions on the front side and the rear side of the vehicle, and have a substantially U shape. The air 8 taken in from the inlet 7 of the air scoop 2 flows in the direction of the arrow, and the flow direction of the air on the front side and the rear side of the intercooler 5 and the inclination angle of the fins 6 substantially match. Further, the fin pitch, which is the distance between the fins 6, is closer on the rear side. This is because the amount of air entering from the inlet during traveling of the vehicle is larger on the rear side, so that the fin pitch is made denser to more effectively release heat.

Next, FIG. 3 shows a plan view of the intercooler alone shown in FIG. An inlet-side tank 9 is provided on the front side of the vehicle, and an outlet-side tank 10 is provided on the rear side of the vehicle. Fins 6 and tubes 11 are provided between the tanks 9 and 10 along the vehicle front-rear direction. The fins 6 are metal plates formed in a wavy shape, and the distance between them becomes closer toward the rear. The front fin pitch L 1 is the largest, which is two to three times the conventional value, and the rear fin pitch L 2
Is the smallest, which is about 1/2 of the conventional value. The planar width D also gradually increases toward the rear. Also,
The tube is also made of metal like the fin, and has a gradually decreasing cross-sectional area toward the rear.

FIG. 4 is a longitudinal sectional view taken along line IV-IV in FIG. The thickness of the intercooler 5 is larger on the front side, and the intercooler 5 is formed in a substantially J-shape in which the height of the upper surface decreases toward the rear. Further, as described above, the inclination of the fin 6 is different between the front and the rear. That is, the front fins 6 are inclined rearward,
The rear fin 6 is formed in a substantially C-shape inclined forward. The inclination angle θ of the fin 6 with respect to the vertical
10 °. When the fins 6 are inclined as described above,
Since the flow direction of the air 8 taken in from the air scoop 2 and the inclination angle θ of the fins 6 are substantially the same, the air 8
The resistance when passing through is reduced. Further, since the rear side has a larger amount of air to be taken in, the heat radiation performance is improved by reducing the fin pitch, and the balance of the heat radiation performance of the intercooler 5 is adjusted.

As described above, according to the heat exchanger of the present invention, (1) the amount of cooling air entering from the air scoop is larger on the rear side of the intercooler, and the pitch of the fins is also higher on the rear side. Therefore, the amount of cooling air passing through the intercooler can be made uniform, and the heat radiation performance is improved. (2) Since the cross-sectional area of the tube is smaller on the rear side of the intercooler, the heat radiation performance is improved. (3) By providing the fins with an inclination, the air resistance when the air entering from the air scoop passes through the intercooler is reduced, and the heat radiation performance is improved.
