Fan with central intake
A fan with central intake comprises a fan frame, a fan wheel and a fan motor. The fan frame provides a hub seat with an annular spacing for fluid flowing through and a joining part at the center of the hub seat for supporting the bearings. The fan wheel is received in the fan frame and provides a hub with an open side and a hollow side with a circular opening. The annular spacing associated with the circular opening constitutes a central flow route for admitting fluid to pass through such that heat from the central area of a radiator under the fan can be dissipated efficiently.
