Abstract:
A heat dissipation device includes a rotor, a plurality of centrifugal blades provided around the rotor, a stator provided inside the rotor for driving the rotor to rotate, and a base provided under the rotor and the stator without enclosing the rotor. The base includes a central portion connected with the stator, and a plurality of extension portions extending from the central portion to the outside. A plurality of holes are formed at a side of each of the plurality of extension portions away from the central portion, respectively.
Abstract:
A coupling structure for a tandem motor includes two bearing sleeves formed with grooves thereon, a connector and elastic fasteners. The connector has a first end and an opposed second end, and each of the first end and second end is formed with at least one groove. A first elastic fastener is fit into the groove of the connector at the first end and received in the groove formed on one of the two bearing sleeve, and a second elastic fastener is fit into the groove of the connector at the second end and received in the grooves formed on the other bearing sleeve.
Abstract:
A rotor assembly includes a housing and a hub. The housing has an open end and an opposed closed end, and is formed with a raised portion in the central location of the closed end. The hub is mounted on the closed end of the housing and covers the housing except for the raised portion to construct a thin motor.
Abstract:
A fan housing assembly includes a mounting base formed with a through hole thereon and a bushing. The bushing has a sleeve and is coupled to the mounting base by connecting the sleeve to the through hole. The mounting base and the bushing can be separately formed with predetermined materials in view of the different quality requirements before being assembled, thus resulting in lower manufacturing cost and enhanced flexibility in the fan design.
Abstract:
An axial flow serial fan includes a single frame, a first rotor vane having at least one first blades; and a second rotor vane having at least one second blades, wherein the first rotor vane and the second rotor vane are provided in series in the single frame along an axial direction to minimize space occupied by the axial-flow serial fan in the axial direction.
Abstract:
A fan frame for encircling an impeller of a fan that includes a base and a plurality of teeth. A hole is formed on the base to form an inner periphery. The plurality of teeth is substantially perpendicular to, and mounted around the inner periphery for encircling the impeller of the fan. A plurality of clearances is formed between each one of the plurality of teeth and its adjacent tooth.
Abstract:
An engagement structure of a fan, which is engaged with a heat dissipation plate having a plurality of heat dissipation fins. A plurality of lower engagement portions with inverted-L-shapes is formed on the plurality of heat dissipation fins. A plurality of clearances substantially parallel to the plurality of heat dissipation fins is formed on each of the lower engagement portions. The engagement structure includes a fan frame and a plurality of upper engagement portions with L-shapes. The plurality of upper engagement portions is elastically mounted around the fan frame. Each of the upper engagement portions includes an L-shaped portion. A plurality of ribs is formed on the L-shaped portions. When assembling the engagement structure with the heat dissipation plate, the L-shaped portions are engaged with the lower engagement portions with inverted-L-shapes for mounting in a vertical direction, while the plurality of ribs are engaged with the plurality of clearances for mounting in a horizontal direction.
Abstract:
A heat-dissipating device and a housing thereof. The housing includes a passage for guiding an air stream flowing from an opening to another opening, wherein an inner wall of the passage at at least one of the opening sides extends radially outwards with a rotational axis of the heat-dissipating device or the passage so as to enlarge intake or discharge area for the air streams. Accordingly, the intake airflow rate may be greatly increased and the heat-dissipating efficiency of the heat-dissipating device may be greatly enhanced without changing assembling conditions with other elements.
