Description

Novel engine cooling fan

Technical Field

The utility model relates to a fan technical field specifically is a novel engine cooling fan.

Background

The engine cooling fan plays an important role in normal operation of the engine as one of the most important heat dissipation components of the engine. The method is widely applied to the fields of automobiles, engineering machinery, hydroelectric engine units and the like.

The engine cooling fan is located either in front of or behind the engine, typically between the engine and the water tank and charge air cooler. It is driven by engine to rotate so as to implement large-amplitude air flow. The heat in the high inlet air temperature in the intercooler and the heat of the engine cooling water circulating in the water tank are continuously driven to the ambient air, and the engine temperature is kept in a stable optimal working range in the circulation.

The heat dissipation characteristic of the fan determines that a fan with excellent performance needs to have the characteristics of large wind pressure and large wind volume, and meanwhile, the fan needs to have lower power consumption, higher static pressure efficiency and lower noise in consideration of economic comfort of users. The existing engine fan with a ring has the advantages of large pressure, enough air quantity, stable and reliable working process and low noise compared with the conventional open fan due to the ring structure, and is widely applied at present.

It is known that the safety and reliability of the fan are greatly reduced by the deflection of the fan during high-speed operation, and the fan is likely to break. A fan with higher performance, less noise and power consumption has become very desirable. Therefore, further upgrading of ring fans with originally good performance is imperative.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides a novel engine cooling fan to solve the problem that mentions in the above-mentioned background art.

In order to solve the technical problem, the utility model provides a following technical scheme:

the novel engine cooling fan comprises a fan mounting plate, fan blades, a fan ring and flow guide ribs fixed on the fan ring, wherein the fan ring is connected with the tail ends of the fan blades, and the inner ends of the fan blades are fixedly connected with the fan mounting plate.

Preferably, the inner ends of the fan blades are fixed on the fan mounting plate in an insert injection molding mode.

Preferably, the fan ring is a trumpet-shaped annular structure.

Preferably, the diversion rib is arc-shaped.

Preferably, the diversion rib is S-shaped.

Compared with the prior art, the utility model discloses possess following beneficial effect:

(1) Because the position of the fan ring close to the air outlet is additionally provided with the flow guide ribs, the air is guided to be layered before air outlet in the operation of the fan, the flow direction of air flow is effectively guided, the air flow passing through the fan has a rectification effect, and the uniformity and stability of the air flow in the operation of the fan are further improved. Particularly, when the fan runs at high speed, the turbulent flow can be effectively reduced, and the swinging of the fan caused by unstable air volume can be reduced. Therefore, the diversion ribs are arranged on the ring, which is not only beneficial to the uniformity and stability of the air quantity, but also can effectively prolong the service life of the fan and reduce the risk of failure.

(2) The flow guide ribs on the fan ring effectively increase the bending resistance of the fan ring, reduce the stress concentration of the ring, improve the strength of the fan ring, reduce the stress and deformation of the fan and enable the structure of the fan blade to be more stable. Meanwhile, due to the structure of the traditional annular fan, the fan is formed by dispersing from inside to outside along each fan blade during injection molding, so that stress concentration is caused at the position where the ring and the ring are in butt joint in the molding process due to the fact that temperature and pressure are not easy to control, at the moment, stress can be effectively released on the flow guide rib as the last molding part due to the existence of the flow guide rib, and the ring with the flow guide rib has higher strength than the ring without the flow guide rib.

(3) The diversion ribs on the fan ring can increase the air pressure at the air outlet side of the fan by changing the angles and the shapes of the diversion ribs on the basis of not changing the general structure of the fan according to the fan performance required by actual working conditions. The increase of the wind pressure at the air outlet side leads the air quantity of the fan to be increased and the performance of the fan to be improved under the condition of not changing the air inlet area. The structure can conveniently improve the performance of the original structure, is convenient to adjust, can further reduce the variety of fan development, and meets diversified requirements.
