Abstract: A fan includes a fan frame and a rotor having a hub, a shaft connected with the hub at its rotation center, blades, and a disk structure connected with the blades and hub within the fan frame. The fan frame has a frame wall having inlet and outlet surfaces, a base carrying the rotor and frame wall, a cover on one side of the frame wall opposite to the base, and a tongue structure between the base and cover. The normal lines of the inlet and outlet surfaces are not parallel to the extension direction of the shaft. The distance between the virtual line segment of the outlet surface and shaft is the shortest distance between the shaft and outlet surface. The extended line from the center of the groove opening of the tongue structure intersects the imaginary plane where the virtual line segment and shaft are located.

Abstract: A cross flow fan includes a fan frame and a rotor having a hub, a shaft connected with the hub at its rotation center, a plurality of blades, and a disk structure connected with the blades and hub within the fan frame. The fan frame has a frame wall having a lateral flow inlet to the rotor and a lateral flow outlet from the rotor, a base carrying the rotor and frame wall, a cover on one side of the frame wall opposite to the base, and a partition structure disposed between the blades and an inner wall surface of the frame wall. A normal line of the lateral flow inlet and a normal line of the lateral flow outlet are not parallel to an extension direction of the shaft. The blades directly face the lateral flow inlet and the lateral flow outlet along radial directions of the shaft.
