Detailed Description
Referring to fig. 1 and 2, the display card module 10a of the present embodiment includes a display card 20 and a fan 100a, wherein the fan 100a is disposed at one side of the display card 20.
In the present embodiment, a fin 30 is further disposed between the fan 100a and the display card 20, and the fan 100a is fixed to the fin 30 through the housing 40. The heat generated by the operation of the display card 20 can be exhausted through the fins 30, and the fan 100a can actively dissipate the heat of the fins 30, so as to accelerate the heat transferred to the fins 30 to be exhausted to the external environment.
Referring to fig. 2 to 4, the fan 100a of the present embodiment includes a hub 110, an outer frame 120, and a plurality of blades 130. In the present embodiment, the outer frame 120 surrounds the hub 110 and has a first annular edge 122 and a second annular edge 124 opposite to each other, and the first annular edge 122 and the second annular edge 124 are disposed along the axial direction X of the hub 110. When the fan 100a is in operation, one side of the first annular edge 122 is an air inlet side, one side of the second annular edge 124 is an air outlet side, and the second annular edge 124 is close to the display card 20.
The plurality of blades 130 extend from the hub 110 to the outer frame 120, respectively. As can be seen in FIG. 3, on one side of the first annular edge 122, a plurality of vanes 130 are flush with or below the first annular edge 122. That is, the plurality of blades 130 do not protrude from the first annular edge 122 of the outer frame 120 when viewed from the entire display card module 10a (fig. 1). Therefore, the appearance of the display card module 10a is beautiful, and the plurality of blades 130 are protected by the frame 120 and are not easily damaged.
As can be seen from fig. 4, at least several blades 1301 of the plurality of blades 130 have a plurality of protrusions 132 away from the hub 110 on the side of the second annular edge 124, and the plurality of protrusions 132 protrude from the second annular edge 124 to the outer frame 120. The size of the plurality of blades 1301 can be increased by the plurality of protruding portions 132, and the plurality of blades 1301 can generate a large air volume. Therefore, the fan 100a of the present invention has a better heat dissipation effect.
Further, since the plurality of protruding portions 132 are disposed in a region away from the hub 110, the plurality of protruding portions 132 do not interfere with components on the hub 110 (fig. 4). Also, since the plurality of protrusions 132 protrude from the second annular edge 124 to the outer frame 120, i.e., from a side close to the display card 20, the plurality of protrusions 132 are located inside the display card module 10 a.
In the present embodiment, the number of the plurality of blades 130 may be odd or even, and each of the plurality of blades 130 has the protruding portion 132.
In the present embodiment, the height of each of the plurality of protruding portions 132 protruding from the second annular edge 124 to the outer frame 120 is a protruding height H, and the protruding height H is between one quarter and one third of the distance D between the first annular edge 122 and the second annular edge 124. Thereby, the plurality of blades 1301 are increased in size enough to effectively increase the air volume, while the plurality of protruding portions 132 are not excessively high, and thus do not interfere with other members near the second annular rim 124.
In the present embodiment, the plurality of blades 130 extend from the hub 110 to the outer frame 120 in a curved manner, that is, the plurality of blades 130 have an arc shape. In addition, each of the plurality of protruding portions 132 may extend onto the second annular edge 124 of the outer frame 120.
In the present embodiment, the length L2 of each of the plurality of protruding portions 132 is between one third and one half of the length L1 that the corresponding blade 1301 extends from the hub 110 to the outer frame 120. Therefore, the plurality of blades 1301 are increased in size enough to effectively increase the air volume, and the plurality of protruding portions 132 can avoid the components on the hub 110 to avoid the problem caused by interference.
It should be noted that the following embodiments follow the reference numerals and parts of the foregoing embodiments, wherein the same reference numerals are used to indicate the same or similar elements, and the description of the same technical contents is omitted. For the description of the omitted parts, reference may be made to the foregoing embodiments, and the following embodiments will not be repeated.
Referring to fig. 5 to 8, the display card module 10b of the present embodiment is similar to the display card module 10a of fig. 1 to 4, and the difference therebetween is: in the present embodiment, the plurality of blades 130 of the fan 100b include a blade 1301 having the protruding portion 132 and a blade 1302 not having the protruding portion 132.
Specifically, in the present embodiment, the number of the plurality of blades 130 is even, and at least several blades 1301 having the plurality of protruding portions 132 among the plurality of blades 130 are arranged along a fixed interval. As shown in fig. 8, in the present embodiment, between any two blades 1301 of the plurality of blades 130 having the plurality of protruding portions 132, one blade 1302 having no plurality of protruding portions 132 is spaced. However, the present invention is not limited to the above, and in other embodiments, two or more blades 1302 not having the plurality of protruding portions 132 may be provided between any two blades 1301 having the plurality of protruding portions 132 among the plurality of blades 130. Alternatively, even if the number of the plurality of blades 130 is an even number, each of the plurality of blades 130 may be the blade 1301 having the protruding portion 132.
In summary, in the fan of the present invention, at least some of the plurality of blades have a plurality of protruding portions away from the hub, and the plurality of protruding portions protrude from the outer frame from the second annular edge. By means of the protruding part, the fan can generate large air volume. In addition, the display card module of the utility model comprises the fan, thereby having good heat dissipation efficiency.
Finally, it should be noted that: the above embodiments are merely to illustrate the technical aspects of the present invention, and not to limit the same; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical means and the utility model described in the foregoing embodiments can be modified, or some or all of the technical features can be equivalently replaced; and such modifications or substitutions do not substantially depart from the scope of the utility model as defined by the appended claims.
