PURPOSE: An advection type fan is provided to enhance cooling efficiency because an air flow to a radial direction in the inside of a fan is not disturbed by a hub. CONSTITUTION: An advection type fan comprises a fan frame(1), a driving module(2), and an impeller(3). The fan frame comprises a first cover unit, a second cover unit, and a lateral wall unit. The lateral wall unit is arranged in between the first and second cover units. The lateral wall unit comprises an air inlet and an air outlet. The driving module accommodates the fan frame, thereby being joined to the first cover unit. The impeller comprises a hub and a plurality of blades. The hub is joined to the driving module to be rotated. The blades are joined to the hub. |
