In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 5 is an AA sectional view of a cooling fan shroud having a heat suction function according to an embodiment of the present invention, FIG. 6 is a sectional view of a cooling fan shroud having a heat suction function according to an embodiment of the present invention, Is a combined state view of a cooling fan shroud having a heat suction function according to an embodiment of the present invention.

The present invention communicates the inside of the engine compartment and the under cover under which air flow phenomenon occurs, thereby eliminating the fluid flow phenomenon by using the pressure difference (see FIG. 3). That is, the air flow inside the engine room is relatively low speed and high pressure state, and the air flow under the under cover is formed by the running of the vehicle at relatively high speed and low pressure.

As a result, a pressure difference is formed between the inside of the engine room and the under cover, so that the inside of the engine compartment and the under cover are communicated with each other so that the hot air inside the engine compartment is discharged to the under cover. Therefore, the fluidity inside the engine room is solved and the low-temperature external air flows into the engine room at the same time, and at the same time, the high-temperature air inside the engine room is discharged to lower the atmospheric temperature inside the engine room.

Hereinafter, the configuration of the present invention will be described in detail.

4 to 7, a cooling fan shroud having a heat suction function, in which a blowing hole 2 is formed so as to allow an air flow generated by the cooling fan 1 according to an embodiment of the present invention to pass therethrough, 100, a first discharge hole 200, and a hollow portion 300.

The suction hole 100 is formed on the upper surface of the cooling fan shroud 3 and serves to suck the accumulated flow inside the engine compartment and the first discharge hole 200 is formed on the upper surface of the cooling fan shroud 3 The hollow portion 300 serves to discharge the sucked rubbing flow to the lower portion of the cooling fan shroud 3 and the hollow portion 300 is formed to communicate with the suction hole 100 and the first discharge hole 200 .

The cooling fan shroud 3 is bent so that the first discharge hole 200 is communicated with the lower portion of the under cover so that the first discharge hole 200 faces the flow direction of the outside air when the vehicle travels .

That is, when the vehicle is running, a flow of air is formed in a direction opposite to the traveling direction of the vehicle. At this time, a fluid sieve phenomenon occurs in the engine room, so that relatively low air flow is formed, and the inside of the engine room becomes relatively high pressure. On the other hand, a relatively high-speed air flow is formed in the lower portion of the under cover, and a relatively low pressure portion is formed in the under cover. That is, a pressure difference is generated between the inside of the engine room and the under cover bottom portion.

Therefore, the low-speed, high-pressure air in the engine room is transmitted to the hollow portion 300 through the suction hole 100. Thereafter, the air passes through the first discharge hole 200 and is discharged to the under cover. At this time, the cooling fan shroud 3 is bent such that the first discharge hole 200 is directed to the flow direction of the outside air when the vehicle is running. This is to minimize the air discharge resistance during driving and to facilitate the discharge of the air inside the engine room.

The cooling fan shroud having the heat suction function is formed on the inner surface of the cooling fan shroud 3 and includes a second discharge hole 400 for communicating the hollow portion 300 with the blow hole 2 . A plurality of the second discharge holes 400 may be formed.

The cooling fan shroud having the heat suction function is connected to the second discharge hole 400 and includes a guide unit 500 for guiding the accumulated flow sucked in the suction hole 100 to the second discharge hole 400, And a control unit. The guide part 500 is formed at a predetermined angle from the rear surface of the cooling fan shroud 3 toward the hollow part 300.

A part of the air delivered to the hollow part 300 passes through the second outlet 400 and is discharged to the blowing port 2. That is, by the operation of the cooling fan 1, a relatively high-speed air flow is generated in the air blowing port 2. Therefore, a part of the air delivered to the hollow portion 300 is discharged to the air outlet 2 through the second outlet 400 because the pressure difference between the hollow portion 300 and the air outlet 2 is generated. Accordingly, it is possible to quickly solve the fluidity phenomenon in the engine room.

At this time, the guide portion 500 is formed in the second discharge hole 400 to guide the discharge of the air from the hollow portion 300 to the air outlet 2. [ The guide part 500 may be formed at a predetermined angle from the rear surface of the cooling fan shroud 3 toward the hollow part 300. The predetermined angle may be determined depending on the performance of the cooling fan 1, And the like. Also, the guide part 500 may prevent the air flow from flowing back from the air outlet 2 to the hollow part 300.

The cooling fan shroud having the heat suction function includes a plurality of support portions 600 disposed between the front surface and the rear surface of the cooling fan shroud 3 so as to partition the suction hole 100. Therefore, the support portion 600 prevents the deterioration of the rigidity of the fan shroud, which was a panel structure in the prior art, due to the volume configuration. In addition, when the air flow inside the engine compartment is discharged to the lower portion of the under cover, the support portion 600 may smooth the air flow and increase the discharge efficiency.

Test results according to the application of the present invention are as shown in Table 1 below.

Temperature Power performance Action interval Fuel efficiency Engine room intake ON:
Decrease 10-15 degrees Celsius Engine torque: 3 ~ 5% improvement Whole area 0.5% improvement Engine room exhaust temperature:
Decrease by 10 degrees Celsius Used Sections 1.0% better

As shown in Table 1, it can be seen that the application of the present invention eliminates the fluid body inside the engine room, thereby reducing the atmospheric temperature of the engine room and the intake / exhaust temperature of the engine room. Thus, it can be seen that the power and fuel efficiency of the engine are maximized.

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory only and are not restrictive of the invention, as claimed, and will be fully understood by those of ordinary skill in the art. The present invention is not limited thereto. It will be apparent to those skilled in the art that various substitutions, modifications and variations are possible within the scope of the present invention, and it is obvious that those parts easily changeable by those skilled in the art are included in the scope of the present invention .
