Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present application provides a heat dissipation fan, including:
a receiving member 1 having a receiving chamber 2;
the fixed shaft 3 is arranged in the accommodating chamber 2, and two ends of the fixed shaft are respectively fixedly connected with the top wall and the bottom wall of the accommodating chamber 2 so as to support the accommodating chamber 2;
the rotating assembly is sleeved outside the fixed shaft 3 and can rotate relative to the fixed shaft 3 at least in part;
and the driving component is at least connected with the fan blade 4 so as to drive the fan blade 4 and the rotating component to rotate.
For example, the heat dissipation fan is disposed in the accommodating component 1, and the accommodating component 1 may be a housing of the heat dissipation fan, or may be an equipment housing, which is not the only one. Fixed axle 3 sets up in accommodation chamber 2, and both ends respectively with accommodation chamber 2's roof and diapire fixed connection, the both ends of fixed axle 3 respectively with accommodation chamber 2's roof and diapire fixed butt, perhaps, roof and diapire are passed respectively at the both ends of fixed axle 3, and with roof and diapire fixed connection, or again, fixed axle 3 still can with accommodation chamber 2's roof and diapire detachable connection, like threaded connection etc., promptly, the both ends of fixed axle 3 and accommodation chamber 2's roof, the diapire corresponds and is equipped with the screwed joint and the thread groove of matching, the screw hole, thereby realize connecting, certainly still can adopt other modes to realize connecting, for example add the fastener that is used for fixing a position fixed axle 3 in accommodation chamber 2, clamping spare etc., do not specifically give unnecessary details. The rotating component is sleeved outside the fixed shaft 3 and at least partially can rotate relative to the fixed shaft, and the fan blades 4 are connected with the rotating component which can rotate relative to the fixed shaft 3, so that the rotating component and the fan blades can be linked. The driving assembly is disposed in the accommodating chamber 2 and interacts with the fan blades 4 to drive the fan blades 4 and the rotating assembly to rotate. The driving assembly may specifically include a driving motor, etc., but is not limited thereto as long as the fan blade 4 can be driven to rotate. Because the rotating assembly is sleeved outside the fixed shaft 3, and the fan blades 4 are connected with the rotating assembly, the fan blades 4 and the rotating assembly are located in the area fixedly supported by the fixed shaft 3, when the accommodating part 1 is extruded by external force, the fixed shaft 3 can firmly support the accommodating cavity 2, and the phenomenon that the area where the fan is located is reduced, the space area where the fan is located is reduced, the air inlet and exhaust space of the fan is influenced, and the heat dissipation performance of equipment is reduced is at least avoided. Specifically, as shown in fig. 2 and fig. 3, the structure diagram of the fan in the prior art and the structure diagram of the heat dissipation fan in the present application show that the first shaft 11 and the second shaft 12 of the fan in the prior art cooperate to realize the rotation of the fan blades 4, and because the first shaft 11 and the second shaft 12 of the fan have a larger interval with the accommodating member 1, when the accommodating member 1 is squeezed, the heat dissipation space of the fan in the prior art is compressed, which affects the heat dissipation performance of the fan, and the squeezed accommodating member 1 is likely to contact with the fan, which may hinder the operation of the fan, and thus the fan is easily damaged. And contrary this application, owing to be equipped with fixed axle 3 in this application, it can effectively support the holding piece and not receive external extrusion, has effectively guaranteed radiator fan's normal operating and the stability in heat dissipation space.
Therefore, the beneficial effects that this application embodiment possesses include that make the roof and the diapire of holding 1 to be propped up through setting up fixed axle 3, and establish runner assembly, flabellum 4 cover and make it rotate round fixed axle 3 outside fixed axle 3, can guarantee that runner assembly and flabellum 4 are located constantly by fixed axle 3 support fixed region, and then guarantee that runner assembly and flabellum 4 can not receive harm, aversion etc. because of holding 1 is pressed, guaranteed heat dissipation space and radiating effect's stability.
Further, the rotating assembly in the embodiment of the present application includes:
the rotating part 5 is hollow, the rotating part 5 is sleeved outside the fixed shaft 3, and the fan blades 4 are connected with the rotating part 5.
For example, the rotating member 5 is a hollow shaft, which is sleeved outside the fixed shaft 3 and connected to the fan blades 4, so as to rotate together with the fan blades 4 around the fixed shaft 3 as an axis under the driving of the fan blades 4. The rotating member 5 can contact the fixed shaft 3, and as in the present embodiment, a safety distance is provided between the rotating member 5 and the fixed shaft 3, so that how the rotating member 5 rotates can be ensured not to contact the fixed shaft 3, that is, any contact between the rotating member 5 and the fixed shaft 3 does not occur. Through this kind of setting, can guarantee that fixed axle 3 can support accommodation chamber 2 more firmly, can not receive the interference that rotates piece 5, especially rotate piece 5 under long-time high-speed operation, if it often takes place to touch with fixed axle 3, the friction will very easily lead to fixed axle 3 to receive wearing and tearing, even with the junction of the roof of accommodation chamber 2, diapire produce the crack, influence the supporting effect of fixed axle 3. As shown in fig. 2 and fig. 3, by comparing the structure of the fan in the prior art and the heat dissipation fan of the present application, the first shaft 11 and the second shaft 12 of the fan in the prior art are tightly attached to each other, and when the fan blades drive the second shaft 12 and the first shaft 11 to rotate relatively, severe friction is generated between the two shafts, which affects the performance of the two shafts and reduces the service life of the two shafts. In the present application, since the safety distance is set between the rotating member 5 and the fixing shaft 4, the above-mentioned undesirable phenomena can be effectively avoided, and the service life of the heat dissipation fan is prolonged.
Further, in order to ensure the rotational stability of the rotating member 5, the rotating assembly in the present embodiment further includes:
the first limiting member 6 is annular and fixed in the accommodating member 1, and the rotating member 5 is located between the fixed shaft 3 and the first limiting member 6 to limit the radial position of the rotating member 5.
That is, the first limiting member 6 is sleeved outside the fixed shaft 3 and is fixedly connected to the bottom wall of the accommodating member 1, so as to ensure the position stability of the first limiting member 6. The rotating part 5 is sleeved outside the fixed shaft 3 and is positioned in an annular region formed by the fixed shaft 3 and the first limiting part 6 in a matched mode, the rotating part 5 can be effectively prevented from radially separating from the annular region when rotating through the limitation of the annular region, the safe distance between the rotating part 5 and the fixed shaft 3 is guaranteed all the time, and namely, the radial position stability of the rotating part 5 can be effectively guaranteed through the first limiting part 6.
Specifically, the rotating member 5 in this embodiment abuts against the first limiting member 6 and can rotate relative to the first limiting member 6. In other words, the peripheral surface of the rotating member 5 is correspondingly abutted against the inner ring surface of the first limiting member 6, and can rotate relatively. In order to ensure that the first limiting member 6 does not slow down or obstruct the rotation of the rotating member 5, the friction coefficient between the first limiting member 6 and the rotating member 5 should satisfy a specific threshold, which is not specifically unique, but is a friction coefficient range, so long as the friction coefficient between the first limiting member 6 and the rotating member 5 satisfies the specific threshold, it can be ensured that the first limiting member 6 does not significantly affect the rotation speed of the rotating member 5. To ensure the coefficient of friction, it may be achieved by restricting the materials of the first restricting member 6 and the rotating member 5, or by applying a lubricant or the like therebetween, or the first restricting member 6 may be provided as an oil-impregnated bearing or the like as in the present embodiment.
Further, in the present embodiment, the fixed shaft 3 is further sleeved with a second limiting member 7 located below the rotating member 5 for assisting in limiting the axial position of the rotating member 5, for example, the second limiting member 7 is also in a ring shape, and is sleeved outside the fixed shaft 3 and located below the rotating member 5, and the second limiting member 7 abuts against the rotating member 5 and allows the rotating member 5 to rotate relative to the rotating member 5. The second limiting member 7 is disposed to stabilize the height position of the rotating member 5 in the axial direction, so that the rotating member does not fall into the annular region, and the first limiting member 6 contacts and rubs against the fan blades 4. Of course, the two may not abut against each other, for example, a hanger is fixed above the rotating member 5, and the rotating member 5 is rotatably installed on the hanger. Similarly, in order to avoid the rotation speed of the rotation member 5 from being blocked due to the contact and abutment of the rotation member 5 and the second limiting member 7, the friction coefficient between the second limiting member 7 and the rotation member 5 also satisfies the above-mentioned specific threshold, specifically, a ball or the like may be disposed between the rotation member 5 and the second limiting member 7, or, as in the present embodiment, the second limiting member 7 may be disposed as a metal oil seal, specifically, it is not necessary.
Further, the fan blades 4 in this embodiment may be directly and fixedly connected with the rotating member 5, or a plurality of fan blades 4 may be fixed on a connecting ring in advance as in this embodiment, so as to fix the fan blades 4 on the rotating member 5 through the connecting ring. In order to prevent the blade 4 from slipping and the rotating member 5 from slipping, a stop member 8 is further sleeved on the fixed shaft 3 above the rotating member 5 in the embodiment, when the rotating member 5 and the blade 4 rotate at too high speed, the rotating member 5 and the blade 4 can be effectively prevented from slipping by the pressing action of the stop member 8, and the stable operation of the fan is ensured. The stop member 8 has a specific structure and a mounting manner, and may be fixedly welded to the fixing shaft 3, integrally formed with the fixing shaft 3, or detachably connected to the fixing shaft 3, such as a threaded connection, a snap connection, or the like.
