Abstract: The present invention relates to a jet structure of a fan rotor, which comprises a fan wheel and at least one connecting channel. The fan wheel has a hub and plural blades disposed on the circumferential side of the hub. The hub has a top portion and a sidewall. Each of the blades has an upper surface and a lower surface which form a high-pressure zone and a low-pressure zone, respectively. The connecting channel is provided with at least one first inlet disposed in the high-pressure zone and at least one first outlet disposed in the low-pressure zone. The first inlet and the first outlet are a first end and a second end of the connecting channel, respectively. By means of the design of the present invention, the effect of noise reduction can be achieved.

Abstract: A fan frame body with bypass structure and a fan thereof. The fan includes a first fan, a second fan and a bypass structure. The second fan has a second frame body correspondingly serially connected with a first frame body of the first fan, whereby a first flow way of the first frame body communicates with a second flow way of the second frame body. The bypass structure is disposed in the first flow way or the second flow way. The bypass structure defines a bypass flow way on a circumference of the first flow way or the second flow way. By means of the bypass structure, without increasing the size of the fan and without increasing the consumed power of the fan, the air volume of the fan can be enhanced.

Abstract: A fan frame body structure and a fan with the fan frame body. The fan frame body structure includes a first fan frame body, a second fan frame body and a connection member. The connection member has a first opening and a second opening. The first and second openings are nonparallel to each other. The first and second fan frame bodies are respectively disposed at the first and second openings. The first and second fan frame bodies are inclined from each other. The first and second fan frame bodies are serially connected in a nonparallel form. Therefore, in the system, due to the resistance of the structure with such configuration, the audio frequency dipole structure is destructed so that the periodical noise and vibration characteristic are lowered.

Abstract: A series fan with support frame includes a first fan, a second fan and a hollow support frame. The support frame has a first receiving space, a second receiving space, an inlet, an outlet and an inclined passage in communication between the first and second receiving spaces. The first and second receiving spaces are respectively positioned in the support frame in adjacency to the inlet and the outlet. The first and second fans are respectively correspondingly received in the first and second receiving spaces. A first virtual central line of the first fan and a second virtual central line of the second fan intersect each other in the inclined passage.

Abstract: A fan structure with non-circular circumference includes a frame, a first hub, a second hub, a transmission belt member, a first assembling member and a second assembling member. A first and a second base are provided in and protruded from a bottom of the frame. The first and the second hub are respectively mounted on the first and the second base, and a stator unit is provided between the first hub and the first base. The transmission belt member is fitted around side walls of the first and second hubs, and has a plurality of blades spaced on an outer surface thereof. The first and the second assembling member are correspondingly assembled to the tops of the first and the second hub. With the above arrangements, the fan structure can operate with largely reduced vibration and noise and can be manufactured at reduced material and production costs.

Abstract: A series fan inclination structure includes an inclined frame body assembly, a first rotor assembly and a second rotor assembly. The inclined frame body assembly has a receiving space. The receiving space includes a first space, a second space and a flow guide passage. A first base seat is obliquely disposed in the first space. A second base seat is obliquely disposed in the second space. The flow guide passage is formed between the first and second base seats in communication with the first and second spaces. The first and second rotor assemblies are correspondingly rotatably disposed on the first and second base seats. The series fan inclination structure is able to greatly reduce the vibration and lower the noise caused by the interaction of the dipole.
