Referring to fig. 1 and fig. 2, which are a perspective view and a top view of a first embodiment of a fan blade structure according to the present invention, as shown in the drawings, the fan blade structure 10 according to the present invention includes a body 110, in the present embodiment, the fan blade structure 10 is shown as being applied to a pumping chamber (not shown) of a water-cooling heat dissipation module, but is not limited thereto, in other embodiments, the fan blade structure 10 may also be applied to other types of pumping chambers, and the application of the fan blade structure 10 is not limited by the present invention.
The body 110 has a first side 111, a second side 112 and a first through hole 113, the first side 111 is located on the upper side of the body 110, the second side 112 is located on the lower side of the body 110, the first through hole 113 communicates with the first and second sides 111, 112, and the first side 111 has a plurality of blades 120 surrounding the first through hole 113. The fan blade 120 has a first end 121 and a second end 122, and in the present embodiment, the first end 121 is adjacent to the outer edge of the first through hole 113.
The fan blades 120 respectively have a first combining portion 123, in the embodiment, the first combining portion 123 is located at the second end 122 of each fan blade 120, but the invention is not limited thereto, and in other embodiments, the first combining portion 123 is located at other suitable positions of the fan blades 120. Also in the present embodiment, the first coupling portion 123 is shown as a groove. The first coupling portion 123 is used to couple with a rotor (not shown), so that the rotor rotates to drive the fan blade structure 10 to rotate.
The fan blade 120 has a first side 124, a second side 125 and a third side 126, the first and second sides 124, 125 are spaced apart from each other and extend from the second end 122 toward the first through hole 113, the third side 126 is connected to the first and second sides 124, 125 at the first end 121 to define a fan blade top surface 127, the outer edge of the body 110 has a virtual line 20, and the virtual line 20 is tangent to a portion 201 of the second side 125 contacting the outer edge of the body 110.
The virtual line 20 forms an included angle X with the second side 125, and in this embodiment, the included angle X is 75 degrees. The virtual line 20 is a virtual line, and is not a physical element or structure of the fan blade structure 10, and is designed to facilitate the user to measure the included angle formed between the virtual line 20 and the second edge 125. In this embodiment, the fan blades 120 are each a block, a first end 121 of the block has a short guiding surface 128 opposite to the third edge 126, and a second end 122 of the block has a long guiding surface 129 opposite to the second edge 125.
A channel 130 is defined between each fan blade 120, the channel 130 is communicated with the first through hole 113, the channel 130 forms a narrow flow passage 131 opposite to the third edge 126, the narrow flow passage 131 has a narrow plane, the channel 130 forms a divergent flow passage 132 opposite to the second edge 125, and the bottom of the divergent flow passage 132 is a divergent plane outward from the first through hole 113. In the pumping chamber of the water-cooled heat dissipation module, a cooling fluid (not shown) can flow in from the first through hole 113 and flow out from the channel 130 between the fan blades 120 through the centrifugal force generated by the rotation of the fan blade structure 10.
When the fan blade structure 10 rotates in the pumping chamber of the water-cooling heat dissipation module, since the cooling fluid flows through the narrow flow channel 131 from the first through hole 113 and then flows through the divergent flow channel 132 from the narrow flow channel 131, the flow velocity of the cooling fluid in the narrow flow channel 131 is fast, when the cooling fluid enters the divergent flow channel 132, the cooling fluid can be decelerated and pressurized, and then the cooling fluid can be discharged to the outside of the fan blade structure 10, and meanwhile, since the pressure in the pumping chamber of the water-cooling heat dissipation module is reduced, the cooling fluid at the first through hole 113 is sucked, so that the cooling fluid outside the first through hole 113 is sucked, and the circulation of the cooling fluid is continued.
In addition, since the fan blades 120 are respectively block bodies, when the fan blade structure 10 rotates, the second ends 122 of the fan blades 120 do not vibrate and generate local thermal stress, so that noise can be reduced and the service life of the fan blade structure 10 can be prolonged.
Please refer to fig. 3 and fig. 4, which are a perspective view and a top view of a second embodiment of the fan structure of the present invention, and refer to fig. 1 and fig. 2, as shown in the figures, part of the structure and functions of the present embodiment are the same as those of the first embodiment, and therefore will not be described herein again, but the difference between the present embodiment and the first embodiment is that the first end 121 of the fan blade 120 is not connected to the outer edge of the first through hole 113, and the virtual line 20 and the second edge 125 form an included angle Y, and in the present embodiment, the included angle Y is 60 degrees.
Thus, the same effect as the first embodiment of the fan structure of the present invention can be achieved.
Referring to fig. 5 and fig. 6, which are perspective views of a fan structure according to a third embodiment of the present invention, and with reference to fig. 1 to 4, as shown in the figures, part of the structure and function of the present embodiment are the same as those of the first and second embodiments, and therefore will not be described herein again, but the difference between the present embodiment and the first and second embodiments is that the first combining portion 123 of the fan blade 120 is shown as a convex body.
Thus, the same effects as those of the first and second embodiments of the fan structure of the present invention can be achieved.
Referring to fig. 7, 8, 9 and 10, which are an exploded view and an assembled view of a rotor assembly according to a first embodiment of the present invention, and an exploded view and an assembled view of an alternative embodiment thereof, and referring to fig. 1 to 4, as shown in the drawings, a rotor assembly 40 according to the present invention includes a blade structure 10 and a rotor structure 30, in the present embodiment, the rotor assembly 40 is shown to be applied to a pumping chamber (not shown) of the water-cooling heat dissipation module according to the first embodiment of the blade structure of the present invention, but not limited thereto, in other embodiments, the rotor assembly 40 may also be applied to other types of pumping chambers, and the present invention does not limit the application of the rotor assembly 40.
The structure and effect of the fan blade structure 10 in this embodiment are the same as the fan blade structure 10 in the first and second embodiments of the fan blade structure of the present invention, and therefore the structure and effect of the fan blade structure 10 will not be described in detail in this embodiment. The rotor structure 30 has a main body 310, and in the present embodiment, the rotor structure 30 can be correspondingly coupled with a stator set (not shown) to induce and excite rotation. The main body 310 has a third side 311 and a fourth side 312, the third side 311 is opposite to the fourth side 312, and the third side 311 of the main body 310 corresponds to the first side 111 of the main body 110. The third side 311 has a plurality of second coupling portions 313, and the first coupling portion 123 of the body 110 is coupled to the second coupling portions 313 of the rotor 310.
In the first and second embodiments of the fan blade structure of the present invention, the first combining portion 123 is located at the second end 122 of each fan blade 120, and therefore, in this embodiment, the second combining portion 123 is located on the third side 311 corresponding to the first combining portion 123. In the first embodiment of the blade structure of the present invention, the first combining portion 123 is represented as a groove, so that in this embodiment, each second combining portion 313 is formed as a protrusion, and the groove of the first combining portion 123 and the protrusion of the second combining portion 313 are correspondingly combined, although the groove and the protrusion may be alternatively arranged oppositely (as shown in fig. 11 to 14).
In this embodiment, the first combining portion 123 and the second combining portion 313 can be combined by any one of riveting, interference fit, adhesion and magnetic attraction, and the invention does not limit the combining manner of the first combining portion 123 and the second combining portion 313. When the stator assembly (not shown) is energized, the stator assembly (not shown) and the rotor assembly 40 generate induced excitation to be converted into mechanical kinetic energy, and then the mechanical kinetic energy drives the rotor assembly, and because the rotor structure 30 and the fan blade structure 10 are combined with each other, the rotor structure 30 can drive the fan blade structure 10 to rotate at the same time, and the cooling fluid can flow out from the channel 130 between the fan blades 120 of the fan blade structure 10 through the centrifugal force generated by the rotation of the fan blade structure 10. Moreover, since the fan blades 120 are respectively block bodies, the same effect as the first and second embodiments of the fan blade structure of the present invention can be achieved when the fan blade structure 10 rotates.
Therefore, the second end 122 of the fan blade 120 of the fan blade structure 10 and the rotor set 40 thereof of the present invention does not generate vibration and local thermal stress, so as to achieve the effects of reducing noise and prolonging the service life of the fan blade structure 10.
The present invention has been described in detail, but the above description is only a preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made according to the scope of the present invention should also be covered by the claims of the present invention.
