摘要： Porous damping material (40) is attached to an entire inner circumference of the fan shroud (20) opposing to an end of a fan (4) and is exposed to opposing space without using conventional perforated metal. Accordingly, jet noise caused by strong swirl between the fan (4) and the fan shroud (20) can be damped by the damping material (40) and impulsive sound scarcely occurs. Thus, both of the impulsive sound and the jet noise can be effectively damped, thereby securely reducing noise. The pours member (401) constituting the porous damping material (40) is a die-molding product made by a die (150) having a cavity (153).
摘要翻译：多孔阻尼材料（40）附接到与风扇（4）的端部相对的风扇罩（20）的整个内周，并且不使用常规的穿孔金属而暴露于相对的空间。因此，由风扇（4）和风扇罩（20）之间的强烈漩涡引起的喷气噪声可被阻尼材料（40）阻尼，并且几乎不发生脉冲声。因此，可以有效地抑制脉冲声和喷射噪声，从而可靠地降低噪音。构成多孔阻尼材料（40）的浇注构件（401）是具有空腔（153）的模具（150）制成的模制产品。

摘要： A blade of a hybrid type fan includes: a blade body 21 made of a synthetic resin; and a metallic insert 22 that is insert molded simultaneously with the blade body 21 and mounted to a mounting arm of a spider. At a corner on an outer side of a radial direction and a forward side of a rotary direction of the insert 22, a bulging portion 26 is provided to bulge toward the outer side of the radial direction and the forward side of the rotary direction. A bulging region 27 of the bulging portion 26 that the most prominently bulges toward the outer side of the radial direction is located to be forward in the rotary direction relative to a mounting center C of the insert 22 and the mounting arm along the radial direction.

摘要： A curved section (12) is provided at a proximal end of a fan (10), so that a rotation locus thereof is configured in a shape conforming to a flow of a cooling air such as center-dented. Accordingly, the cooling air can be smoothly sucked in by the fan (10) as well as fan shroud along an arcuate section on an inlet side. Further, since natural flow toward radially outward flow of the cooling air can be guided by an arcuate section on an outlet side, thus smoothly discharging the cooling air. Therefore, the flow of the cooling air can be made smooth entirely from upstream to downstream, thus increasing flow rate and reducing noise.
摘要翻译：弯曲部分（12）设置在风扇（10）的近端处，使得其旋转轨迹被构造成符合诸如中心凹陷的冷却空气的流动的形状。因此，可以通过风扇（10）以及沿着入口侧的弓形部分的风扇罩平滑地吸入冷却空气。此外，由于朝向冷却空气的径向向外流动的自然流动可以由出口侧的弓形部分引导，从而平滑地排出冷却空气。因此，冷却空气的流动可以从上游到下游完全平滑，从而增加流量并降低噪音。
