Referring to the drawings, a general vehicle fan shroud 1 includes a fan 3 driven by a motor, a shroud 2 for guiding the flow of air, Is disposed on the rear surface of the radiator grille in the automobile engine room.

On the other hand, in the case of a vehicle running on a road covered with snow in the winter season, the snow on the road penetrates through the front grille of the vehicle and is accumulated in the fan shroud 1. The accumulated snow is melted by the surrounding heat, (Fig. 1, part a). At this time, the collected moisture is frozen by the low temperature around the vehicle while the vehicle is stationary, and becomes ice of a predetermined size. Thereafter, when the vehicle runs again, there is a problem that the fan collides with ice and is damaged. Further, there is a problem that the fan is fixed when ice is frozen and the motor for rotating the fan is burned. Accordingly, it is necessary to prevent moisture from collecting in the lower portion of the fan shroud 1.

Prior art to the present invention is disclosed in Japanese Patent Application Laid-Open No. 2007-27807 (motor-integrated fan shroud structure).

The present invention has been made in order to meet the above-mentioned need, and it is an object of the present invention to provide a vehicle fan shroud which allows the snow accumulated in the pan shroud of a vehicle that has driven on the snow road to be liquefied, Wood. &Lt; / RTI >

Referring to FIG. 2, the vehicle fan shroud 100 according to the embodiment of the present invention includes a shroud 120, a front drain guide 130, and a rear drain guide 140.

The fan shroud 100 is generally rectangular and includes a circular shroud 120 with a fan 3 disposed at the center of the fan shroud 100. Here, the fan 3 can be rotated at a predetermined rotation speed by a motor (not shown) operated by an external power source.

The shroud (120) guides the flow of air generated by the fan (3). The inner diameter of the shroud 120 corresponds to the turning radius of the fan 3. That is, the inner diameter of the shroud 120 is close to the outer end of the fan 3 but is spaced apart from the outer end of the fan 3 by a predetermined distance when the fan 3 rotates, It is preferable not to come into contact with the inner peripheral side.

Referring to FIGS. 3 and 4, it can be seen that a drain hole 122 having a predetermined size is formed on the lower side of the fan shroud 100.

The drain hole 122 is formed by penetrating the fan shroud 100 from the rear to the front. The drain hole 122 can drain the moisture generated from the outside of the snow to the front or rear of the fan shroud 100. Therefore, when snow flows in from the outside, water generated by the snow due to the surrounding heat can be drained through the drain hole 122.

A front drain guide 130 and a rear drain guide 140 are applied so that water can be easily drained to the front or rear of the fan shroud 100 through the drain hole 122.

As shown in FIG. 5, the front drain guide 130 and the rear drain guide 140 are connected to the front and rear of the drain hole 122. The front drain guide 130 and the rear drain guide 140 guide the drainage of water through the drain hole 122 easily.
