Abstract

The utility model discloses an automobile fan. The automobile fan adopts the structure that a flow separator is arranged at the junction part between the root on the reverse side of each fan blade of the fan and a fan journal; a guide vane is arranged on the front side curved surface of each fan blade; and the guide vanes are connected with the flow separators. As the guide vanes and the flow separators are designed on the fan so as to guide eddy flow in clearance, the eddy flow which can reduce the efficiency of the fan originally can enhance the efficiency of the fan conversely, and the air volume of the fan can be improved. By optimizing the structure of the cooling fan, the utility model can increase the heat dissipation air volume of the cooling fan, thereby enhancing the cooling capability of a cooling system, improving the service performance of an engine, and prolonging the service life of the engine.

Description

A kind of automobile fan

Technical field

The utility model relates to automobile cooling system, especially a kind of automobile fan.

Background technique

Cooling fan is one of important component of automobile engine system, and the cooling capacity of fan has very significant effects to motor.The effect of cooling fan is exactly to cooperate cooling system to make the temperature of motor remain on optimum working temperature; If the cooling capacity deficiency of fan can make the water temperature of motor too high, cause its performance to reduce, reduce working life.

There is inevitable gap in domestic automobile fan commonly used at present, and air produces eddy current in the crack during this time, reduces fan efficiency, owing to fully wind energy is not acted on the motor, causes the unnecessary wasting of resources, can not protect motor fully.

Summary of the invention

The purpose of this utility model is the heat radiation air quantity that increases cooling fan by the internal structure of optimizing cooling fan, thereby increases the cooling capacity of cooling system, and the usability and the working life of improving motor, the spy proposes a kind of automobile fan.

The technical solution of the utility model is for this reason, a kind of automobile fan, comprise fan body, it is characterized in that: root and fan axle journal jointing place at every flabellum reverse side of described fan are provided with flow separator, and on the curved surface of the front of every flabellum, being provided with stator, this stator is connected with flow separator.

Beneficial effect:

The utility model is provided with flow separator in the root and the fan axle journal jointing place of every flabellum reverse side, the front curved surface of every flabellum is provided with stator, this stator is connected with flow separator, eddy current channeling conduct to gap portion, make the eddy current of original reduction fan efficiency can add the efficient of strong wind fan on the contrary, improve the air quantity of fan, strengthened the air quantity of fan, improved the cooling capacity of whole cooling system, the air quantity of conventional fan is significantly increased on year-on-year basis.

Description of drawings

Fig. 1 is a plan view of the present utility model.

Fig. 2 is a shaft side figure of the present utility model.

Embodiment

As shown in Figure 1 and Figure 2,1 is stator, and 2 is flow separator, the 3rd, and fan body.

In the manufacture process of fan, the root of each flabellum reverse side of fan body 3 and fan axle journal jointing place are provided with flow separator 2, and are provided with stator 3 on the curved surface of the front of every flabellum, and this stator 3 is connected with flow separator 2.Flow separator 2 and stator 1 are carried out integrated injection moulding with fan 3, can guarantee the working life of fan.The injection moulding position of flow separator 2 and stator 1 is positioned at the inner ring of fan, and it is on the low side to have remedied inner ring fan linear velocity, and air is difficult for the defective of polymerization, can significantly improve the air quantity of fan, under the situation that does not increase fan diameter, has improved the performance of fan.

This fan 3 is installed between motor and the radiator, increases the heat radiation air quantity of cooling fan, thereby increase the cooling capacity of cooling system, the usability and the working life of improving motor by the structure of optimizing cooling fan.

Claims (1)

1. an automobile fan comprises fan body, it is characterized in that: root and fan axle journal jointing place at every flabellum reverse side of described fan are provided with flow separator, and are provided with stator on the curved surface of the front of every flabellum, and this stator is connected with flow separator.
