Abstract

The utility model discloses a fan which comprises a rotor assembly, a frame main body, an oil-retaining bearing and at least one heat dissipation structure, and the rotor assembly comprises an axis. An accommodating space for accommodating the rotor assembly is formed in the frame main body, and a preset area capable of dissipating heat is arranged on the frame main body; the oil-retaining bearing is fixed on the frame main body, and the axis is pivoted in the oil-retaining bearing; and the heat dissipation structure is connected with the oil-retaining bearing and extends to the preset area from the oil-retaining bearing. According to the fan, the friction section of the oil-retaining bearing and the axis can be regarded as the heating end, the acting heat dissipation area of the heat dissipation structure and the rotor assembly is regarded as the cold end, heat is transmitted to the cold end from the heating end, the temperature of the oil-retaining bearing can be effectively reduced, and therefore the service life of the fan is prolonged.

Description

technical field [0001] The present application relates to the field of fans, in particular to a fan. Background technique [0002] As an active cooling element, fans are widely used in the PC industry, communication industry, medical equipment and consumer electronics industry. [0003] The service life of the fan depends on the selection of fan bearings. At present, there are two types of bearings: roller bearings and oil bearings. The life of roller bearing fans will be longer than oil bearings, but in addition to being expensive, the noise caused by ball bearings is quieter. It will cause hearing discomfort in the working environment. Oil-bearing fans are cheaper, but their service life is shorter than that of ball bearing fans. The noise generated by the fan operation is lower than that of ball bearing fans, and the sound quality is better than that of ball bearing fans. Therefore, for indoor products, many designers and Individual consumers prefer oil bearing fans. H...
