Description
Technical field
The present invention particularly can effectively reduce noise and fan that increases blast and fan frame thereof about a kind of about a kind of fan and fan frame thereof.
Background technique
Along with electronic product towards high-performance, high frequency, high-speed and lightening developing rapidly; Cause the heating temperature of electronic product also increasingly high; Thereby be easy to generate wild effect; Influencing product reliability, is to become one of important topic of present electronic product development how to solve heat dissipation problem.
Fan is a kind of traditional sink, to different system the time, uses the fan of different qualities curve to satisfy the demands, and when keeping or promoting the blast characteristic, the reduction of noise usually is the key factor of fan when selecting for use.
In view of this, how to provide a kind of and reduce noise and keep fan and the fan frame thereof of fan duty effectively electronic component heat energy is taken away originally, real is one of important topic.
Summary of the invention
Therefore, for addressing the above problem, the present invention provides a kind of and can effectively reduce noise and keep or promote fan and the fan frame thereof of stream condition effectively electronic component heat energy is taken away originally, to promote the environmental quality on using.
For achieving the above object, the present invention provides a kind of fan, and it comprises an impeller, a motor and a fan frame.Motor is connected with impeller and drives impeller is rotated, and the fan frame is in order to ccontaining impeller and motor.In addition; The fan frame also comprises a body; One forms the internal ring portion of a runner, and one forms the chamfered corners of fan outlet, and chamfered corners links to each other with internal ring portion; One motor base then is arranged at the centre of runner in the body, and a plurality of supporting members then are connected between body and the motor base and have one unsettled section and are not connected with above-mentioned chamfered corners.
Hold the above, according to a kind of fan of the present invention and fan frame thereof, the design that provides a supporting member not to be connected with the chamfered corners of exhaust outlet can effectively avoid air-flow to increase the noise decibel in chamfered corners again because of unnecessary structure produces drag effects blast characteristic.
For letting above-mentioned and other purposes of the present invention, characteristic and the advantage can be more obviously understandable, hereinafter is special lifts a preferred embodiment, and conjunction with figs., elaborates as follows:

Embodiment
Below will a kind of fan and fan frame thereof according to preferred embodiment of the present invention be described with reference to relevant drawings, wherein components identical will be explained with identical reference marks.
Please with reference to Fig. 1 and shown in Figure 2, comprise an impeller 11, one motors 12 and a fan frame 13 according to a kind of fan 10 of preferred embodiment of the present invention, motor 12 is connected with impeller 11 and drives impeller 11 rotations, fans frame 13 in order to ccontaining impeller 11 and motor 12.In addition, fan frame 13 comprises that also a body 131, forms the chamfered corners 133 of internal ring portion 132, the one formation fan outlets of a runner.
Chamfered corners 133 links to each other with internal ring portion 132; Between the internal ring portion 132 that 134 centre that are arranged at runner in the body 131 of one motor base, 135 of a plurality of supporting members are connected in body 131 and the motor base 134 and have one unsettled section B at adjacent internal ring portion 132 places and be not connected with above-mentioned chamfered corners 133.Fan 10 of the present invention is applied to electronicss such as power supply unit, server, communications equipment, automotive electronics or computer.The body 131 of fan 10 is roughly rounded, ellipse or polygonal.
Please be simultaneously with reference to Fig. 2 and Fig. 3; With body 131 integrally formed supporting members 135 be stator blade or rib form; Shape then is wing or planar; Supporting member 135 links to each other to body 131 extensions and with internal ring portion 132 from motor base 134 and forms a linkage section A, and linkage section A length is more than or equal to the degree of depth of unsettled section B, and the lateral projection of unsettled section B and runner center line C parallel (as shown in Figure 2) or not parallel (as shown in Figure 3).
When design supporting member 135, fan frame 13 has the length of side with centimetre metering, and the quantity of supporting member 135 is 1.3 times integer greater than this length of side, so that fan frame 13 has the supporting member 135 of sufficient amount enough blast and protection is provided.Under this design, when the spacing of adjacent two supporting members 135 was the column measurer F test of 12mm with a diameter, column measurer F can't stretch into be as the criterion (as shown in Figure 1) from 135 of adjacent supporting members.Thus, can reach the impeller 11 of the protective action person's of avoiding the use of finger false touch rotation.
In sum; According to a kind of fan of the present invention and fan frame thereof; Provide one not to be connected and to have a supporting member of one unsettled section with the exhaust outlet chamfered corners; In the time of can effectively avoiding structure to be connected, the air-flow through chamfered corners is produced resistance, effectively keep or promote the blast characteristic and reduce air-flow and the noise (as shown in Figure 4) of structure impact generation with chamfered corners.
Though the present invention with a preferred embodiment openly as above; Right its is not in order to limit the present invention; Any those skilled in the art; Do not breaking away from the spirit and scope of the present invention, when can doing various changes and retouching, so protection scope of the present invention is as the criterion when looking the accompanying Claim book person of defining.
