In this embodiment, two cooling fans 300 are arranged on the inner peripheral side of the fan shroud 310, but only one cooling fan 300 may be arranged on the inner peripheral side of the fan shroud 310, or three cooling fans 300 may be arranged. You may distribute more than that. Further, an air guide duct may be connected to the front side of the mounting shroud 1 in order to completely block the heated air flowing around the front side of the condenser 200. A partition wall may be provided inside the mounting shroud 1 or the fan shroud 310 to partition the inside into a plurality of air passages.

[0029]

According to the present invention, the condenser and the fan shroud can be attached to both sides of the radiator at the same time by fastening the attached leg portion and the attaching leg portion of the fan shroud together. Therefore, it is possible to reduce the work of tightening the bolts and the like required when fixing the condenser and the fan shroud to the radiator, respectively, and further reduce the number of parts such as the bolts, thereby reducing the work man-hour and the cost. be able to. In addition, since the tubular part covers the outer circumference of the condenser and the fan shroud covers the outer circumference of the cooling fan, the heated air heated when passing through the radiator is condensed again on the front side of the radiator and the condensation. It is possible to prevent wraparound to the front side of the container.
