COOLING STRUCTURE FOR RADIATOR FOR WATER-COOLED POWER UNIT

摘要

Disclosed is a radiator cooling structure for cooling a radiator 67 of a water-cooled power unit mounted on a small vehicle and disposed on a laterally outer side of the small vehicle, which radiator cooling structure improves the efficiency of cooling an internal combustion engine 16 by using a head wind. The radiator 67 is provided with a radiator cover 68 having a louver 69 for guiding cooling air to the radiator 67. The louver 69 is formed such that a rear part thereof is more protruded laterally outward than a front part thereof. The louver 69 of the radiator cover 68 has parallel slats 69a tilting forward, and a lower body cover 13A is provided with a cooling air intake opening 70 capable of guiding a head wind toward the louver 69 positioned obliquely above and rearward of the cooling air intake opening 70.
