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.

Abstract: A fan frame includes a first frame and a second frame. The first frame includes at least a first sidewall and a first connecting element, wherein the first connecting element is disposed on the first sidewall. The second frame includes at least a second sidewall and a second connecting element, wherein the second connecting element is disposed on the second sidewall and at least partially overlapped with the first connecting element. The second connecting element includes a first end and a second end in a first direction, wherein the first end and the second end are bent toward the first connecting element, respectively, for grasping the first connecting element. As a result, the accuracy error and the precision error are avoided, the stresses are internally counterbalanced, and the deformation of the fan frame is avoided.
