た。 Such a cooling system consists of a shroud installed in the radiator that acts as a guide plate and a fan installed in the cylindrical part of the shroud.The required clearance between the fan blade and the shroud makes it possible to operate the fan at particularly high speeds when the fan rotates. When the rotation or low speed rotation occurs, a backflow, ie, air turbulence occurs in the vicinity, causing noise generation and a reduction in the cooling effect.

る。尚、同図１２は括れ部である。 In the figure, R is a radiator, and a resin shroud 5 is provided on one side of the radiator. 6 is a press fan with a blade shape based on blade theory;
As shown in the figure, four blades 8 are arranged radially on a central boss portion 7, and a flat ring 9 is integrally provided around the outer periphery of the blades 8. A cylindrical portion 10 at the center of the shroud 5 is provided with an annular storage portion 11 for storing the ring 9 of the fan 6. Since this annular storage portion 11 is for storing the ring 9 of the press fan 6, it only needs to have a width slightly larger than the thickness of the ring 9, and the length of the cylindrical portion 10 of the shroud 5 is It doesn't need to be long. As shown in FIG. 4, the fan 6 is provided within the cylindrical portion 10 of the shroud 5 with the ring 9 housed within the annular housing portion 11. Note that FIG. 12 shows a constricted portion.

できる。 In this way, if the ring 9 of the fan 6 is stored in the storage part 11 of the shroud 5, there will be no clearance between the fan 6 and the shroud 5, and the backflow that occurs near the fan 6 and the shroud 5 due to the clearance will be eliminated. In other words, air turbulence is eliminated, noise generation is prevented, and the cooling effect is sufficiently exhibited. Of course, since the fan 6 is integrally provided with the ring 9, its mechanical strength can also be increased.

２で逆の方向に捻つて連結されている。 6 and 7 show other embodiments of the connection structure between the blade 8 of the fan 6 and the ring 9 provided integrally around its outer periphery. Noise is prevented and the cooling effect is sufficiently exhibited. FIG. 6 shows an example in which the constricted portion 12 is provided between the wing 8 and the ring 9 as described above. Fig. 7 shows an example without the constricted portion 12, and although the mechanical strength of the fan shown in Fig. 6 is slightly weaker than that of Fig. 7, the resistance is small and the weight can be reduced. The intensity of the target will increase. Note that the blade 8 tilted in one direction and the flat ring 9 are connected to this constricted portion 1.
2, they are connected by twisting in the opposite direction.
