摘要： A rotor shaft includes a main body having a central portion and an extension portion. The extension portion has a plurality of extension sections radially outward extended from the central portion by different distances to together define a peripheral surface and a non-circular cross section of the main body. In a cooling fan using the rotor shaft, the main body of the rotor shaft is received in a shaft space internally defined by a bearing of the fan, and a lubricant is filled in a space left between the main body and the shaft space. With the non-circular cross section of the main body of the rotor shaft, the lubricant filled between the rotor shaft and the shaft space can have increased support pressure to thereby reduce the noise and vibration caused by frictional contact of the rotor shaft with the bearing during the operation of the cooling fan.

摘要： An oil-retaining bearing fan structure includes a fan base seat, an oil-retaining bearing and at least one magnetic member. The oil-retaining bearing is disposed in a bearing hole of the fan base seat. The magnetic member is disposed between the oil-retaining bearing and a wall of the bearing hole. The magnetic member serves to apply a magnetic attraction force to a shaft of the fan structure to make the shaft quickly restore to its optimal operation position so as to reduce wear and lower the noises and vibration of the fan structure in operation. Therefore, the lifetime of the fan structure can be prolonged.

摘要： A temperature controlling system for a LED module includes at least one LED unit, at least one fan, at least one temperature sensor and a controlling device. The controlling device generates a driving signal for controlling the rotating speed of the fan based on a temperature detection signal transmitted from the temperature sensor, so that the fan can generate a compulsive airflow for dissipating the heat generated by the LED unit. According to the present invention, the working temperatures of the respective LED units can be kept the same, and a uniform heat-dissipating effect can be achieved.

摘要： A thermal module includes a heat radiating unit, a heat transfer unit, and at least one cross-flow fan. The heat radiating unit has an air inlet and an air outlet that communicate with each other. The heat transfer unit has a heat absorbing section attached to a heat source and a heat dissipating section extended from the heat absorbing section to connect to the heat radiating unit. The cross-flow fan is arranged opposite to the heat radiating unit with an air-out side of the cross-flow fan located adjoining to the air inlet of the heat radiating unit. With the above arrangements, the thermal module occupies a largely reduced area while providing largely upgraded heat dissipation effect.
