Abstract
A thin cooling fan (1) includes a fan shell (10), a motor (20), a plurality of blades (30), and a PCB (40). The fan shell (10) comprises a base plate (11) and a shell cover (12) which cover to each other to form an inner space (100). The base plate (11) has a first surface (111) facing toward the inner space (100) and a second surface (112) having a receiving space (101) and opposite to the first surface (111). The motor (20) is combined in the inner space (100). The blades (30) are disposed in the inner space (100) and rotated by the motor (20). The PCB (40) is disposed in the receiving space (101) and flush with the second surface (112). Thus, the whole thickness of the cooling fan (1) is reduced and the flow channel design in the inner space (100) is not affected.
