COOLING FAN

摘要

PURPOSE: A cooling fan device is provided to enhance the standardization and productivity of work by improving an assembling structure of a heat sink and heat discharging fan. CONSTITUTION: The cooling fan comprises a heat sink(10) discharging heat transferred from an IC package by heat exchanging and a heat discharging fan(20) improving cooling efficiency by forcible convection operation by providing wind blow to the heat sink. The heat sink consists of a base having a plain lower surface in order to closely contact to a heat emitting surface of IC package and a cooling pin to rapidly discharge the heat transferred from the base to the atmosphere. The cooling pin is formed as a single body with the base and is formed in a lattice arrangement perpendicular to the base having a fixed space. The heat discharging fan uses a general motor having a blade(22) to generate wind blow. The heat sink and heat discharging fan is connected by simple insertion assembling without using a screw. The heat sink is equipped with a perpendicular cylindrical post(30) formed in a single body with the cooling pin at the corner. An insertion part(31) formed in the top of post is inserted to a connection part(36) of connection bracket(35).
