COOLING STRUCTURE OF RADIO BASE STATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To position an axial fan and a unit close to each other without causing variations in heat generation. SOLUTION: An air duct device 16 having a parallel surface 16a which is parallel to the axe of an axial fan 10, and an inclined surface 16b which is inclined from the parallel surface 16a on the side end of the axial fan 10 to the direction of the unit 14 is placed in a part where no fin 12 is placed in such a way that the air from the axial fan 10 is conducted to the direction of the fins by the parallel surface 16a and the inclined surface 16b.
