困難になるなどの問題があつた。 The required heat dissipation area of a radiator is determined in proportion to the amount of heat generated by the engine, and if you try to keep the height down, you end up with a horizontally long radiator. This has caused problems such as difficulty in effectively cooling with a cooling fan.

(Means for Solving the Problems) Therefore, the present invention provides a cooling system for an automobile engine in which two annular water tanks are installed at the front of the engine on both left and right sides with respect to the traveling direction of the automobile. The two tanks are arranged so that their axes coincide with each other, and the two tanks are communicated with each other through a plurality of water tubes, and a donut-shaped disk-shaped plate fin is perpendicular to the water tubes and fixed thereto, between the two tanks. A plurality of cooling fans are disposed on the inner diameter portions of the water tanks on both sides, and each cooling fan is rotatably driven by the same drive device so as to blow air from the center toward the outside in the axial direction. is used as a means to solve problems.

Figure 1 is a front view of a radiator according to an embodiment of the present invention, Figure 2 is a side view of Figure 1, and Figure 3 is a view of a plate fin. The side view of FIG. 4 shows the radiator 1 of FIG. 1 mounted on an automobile. Note that 9 in FIG. 4 is an engine.

ピツチで取付けられている。 First, to explain the radiator 1 in FIG. 1, 2 and 3 are water tanks formed in an annular shape with a rectangular cross section, and are arranged on both left and right sides, respectively. It is connected via tube 4. The cross-sectional shape of the water tube 4 is formed into a rectangular or oval shape having a longitudinal direction parallel to the vehicle traveling direction, as shown in FIG. Numeral 5 is a donut-like disc-shaped plate fin fixed perpendicularly to the water tube 4, and a plurality of plate fins are installed between both tanks 2 and 3 at equal pitches.

れている。 Cooling fans 6 and 7 are rotatably driven by a drive device 8 through the same shaft 10, using the inner diameter surfaces of the water tanks 2 and 3 as shrouds, and blow air outward. Note that the drive device 8 uses an electric motor, a hydraulic motor, or the like, and is built into the core.

フイン５の熱を奪つて流れる。 Next, the effect will be explained. If the water temperature rises when the vehicle is stopped (idling), the cooling fan 6,
7 is rotated by a drive device 8 via a shaft 10, and the air flows outward as indicated by the dotted arrow in FIG. 1, taking away the heat from the plate fins 5.

抗に比べて遥かに小さい。 Also, when the car is running, wind flows from the outside from the front of the radiator 1, as shown by the dotted arrow in Figure 2.
Removes heat from plate fin 5. At this time, the driving device 8 and the shaft 10 act as resistance to the wind blowing due to the vehicle speed.
This is much smaller than the conventional (fan + shroud) resistance.

Since the present invention is configured as described above in detail, only the drive device and its shaft provide resistance to the wind blowing due to the vehicle speed, which is much smaller than the resistance of a conventional fan shroud. Therefore, if the necessary core area during idling can be secured, a more compact design can be achieved. In addition, conventionally, the fan shroud was manufactured and assembled separately from the radiator, but the present invention has the advantage of being able to share the inner plate material of the water tank. The diameter of the cooling fan can be made smaller than that of a conventional cooling fan with an electric motor or a known viscous fluid coupling. Therefore, even if the cooling fan has the same diameter, its effective diameter can be increased. Further, in the present invention, since the water tanks of the annularly formed radiator are arranged on both the left and right sides, the height dimension can be kept low and the cooling fan can be used effectively.
