Problems solved by technology

However, although the ring-type cooling fan has ultra-thin blades, due to the increase of the guide ring, the mass will increase, the moment of inertia will also increase, and the power consumption will also increase. Therefore, when designing the guide ring, it is always hoped th

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the embodiments and the accompanying drawings.

[0013] Referring to Fig. 1-Fig. 3, a ring-type cooling fan with a reinforced guide ring is composed of a tray 3, a hub 1, fan blades 2, and a guide ring 4. The fan blades 2 and the guide ring 4 are connected together, and the material is A wire mesh circle 5 is embedded in the diversion ring 4 of the modified reinforced nylon, and the metal mesh circle 5 is embedded in the outer edge of the diversion ring 4 .

[0014] Referring to Fig. 4, the wire mesh circle 5 grids are plain weave.

[0015] Referring to Fig. 5, the grid of wire mesh ring 5 is twill weave.

[0016] Referring to Fig. 4 and Fig. 5, the mesh number of the wire mesh circle 5 is 5.

[0017] The invention not only has the advantages of small jump, good static balance, low noise, no eddy current during operation, little airflow secondary circulation between the fan and the wind guide co...

Abstract

The invention discloses a flow guiding ring reinforced type ring type cooled fan for car engine cooled system, which is characterized by the following: comprising with tray, boss, fly and flow guiding ring; connecting the fly and the flow guiding ring together; embedding metal mesh ring into the flow guiding ring with modified reinforced nylon as material; embedding the metal mesh ring on the outer rim of the flow guiding ring. This metal mesh can increase durability, tenacity and intensity of the flow guiding ring greatly.

Description

1. Technical field [0001] The invention relates to a cooling fan, in particular to an annular cooling fan used in a cooling system of an automobile engine. 2. Background technology [0002] The fan blades of ordinary cooling fans are open in the radial direction, so they are also called opening fans. In order to ensure the strength and rigidity of the fan blades, the fan blades gradually become thinner from the center of the hub radially outward (equal strength design), and are easily deformed during injection molding. Therefore, the jump is large, the unbalance is large, and the noise is large; there is an eddy current during work, and there is a secondary air circulation between the fan and the wind guide cover, so the energy consumption is also large, and the economy is not good. The ring-type cooling fan is an invention in recent years, which improves the streamline of the fan blades and adds a guide ring on the basis of the ordinary cooling fan. The ring-shaped coolin...
