Abstract (en)
A fan shroud is mounted on a radiator for guiding air flow around an axial fan of a liquid cooled internal combustion engine. The fan shroud includes a mouth portion (16) which extends coaxially with the central axis of the fan. A plurality of fin plates (18) are circumferentially disposed at regular intervals on the inside surface of the mouth portion. The fin plates projects radially inwardly into the space between the fan and a core of the radiator. Within the space, irregular patterns of turbulent flow are controlled and transformed into regular patterns flying toward axial directions, whereby a volume of air flow increases and a fan noise per volume is diminished.
