Description

Technical Field

[0001] This utility model belongs to the technical field of cooling fan equipment, and in particular relates to a high-efficiency cooling fan. Background Technology

[0002] With the rapid development of electronic technology, the operating speed of heat-generating electronic components such as central processing units is getting faster and faster, and the heat generated during operation is also increasing accordingly. In order to dissipate this heat and ensure the normal operation of electronic components, the industry uses fans to cool electronic components. Traditional fans generally include a stator, a rotor, and a frame that houses the stator and rotor. The rotor usually includes a hub and several fan blades evenly arranged around the hub and radiating outwards. In the existing technology, the fan rotation drives the air to flow from one side of the heat dissipation device to the other side, moving the heat on the CPU to achieve the heat dissipation function. However, the existing cooling fans have a single heat dissipation path during use, which affects the heat dissipation efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a high-efficiency cooling fan, which aims to solve the technical problem of low heat dissipation efficiency of existing cooling fans.

[0004] To achieve the above objectives, this utility model provides a high-efficiency cooling fan, including a mounting frame, fan blades, and a heat dissipation ring. The mounting frame has a main ventilation hole and at least one side ventilation hole, which are connected to each other. A drive device is disposed in the main ventilation hole within the mounting frame. The fan blades are fixedly mounted on the rotating end of the drive device. The heat dissipation ring is also disposed within the heat dissipation ring, and the edges of each blade are fixedly connected to the inner surface of the heat dissipation ring. The side ventilation hole is disposed opposite to the outer surface of the heat dissipation ring.

[0005] Preferably, the heat dissipation ring includes a collar and a plurality of exhaust plates, each blade being fixedly connected to the inner side of the collar, and each exhaust plate being arranged at intervals around the outer side of the collar.

[0006] Preferably, the exhaust plate is bent and inclined to one side from the connection end with the side of the collar, and the bending direction of the exhaust plate is the same as the bending direction of the blade.

[0007] Preferably, the top of the exhaust plate is provided with a clearance notch, which penetrates the free end side of the exhaust plate.

[0008] Preferably, the connection surface between the clearance notch and the collar is an arc-shaped curved surface.

[0009] Preferably, the free end side of the exhaust plate is provided with an arc-shaped curved surface.

[0010] Preferably, the mounting frame includes a carrier plate and a protective housing, the driving device is disposed on the carrier plate, the main ventilation hole is disposed on the protective housing, and the main ventilation hole is connected to the air inlet on the carrier plate.

[0011] Preferably, the carrier plate is provided with a mounting bracket, the mounting bracket is located in the air inlet, and the drive device is fixedly mounted on the mounting bracket.

[0012] Preferably, the mounting bracket is provided with several cable trays.

[0013] Preferably, the protective housing is provided with a plurality of downwardly extending fasteners, each of which is engaged with the carrier plate.

[0014] The high-efficiency cooling fan provided in this embodiment of the present invention has at least one of the following technical effects:

[0015] The high-efficiency cooling fan of this invention is assembled from a mounting frame, fan blades, and a heat dissipation ring. The fan blades and heat dissipation ring are integrally formed, so that the fan blades rotate while driving the heat dissipation ring to rotate, achieving simultaneous airflow from both fan blades and the side airflow from the heat dissipation ring. During manufacturing, a main ventilation hole and a side ventilation hole are opened on the mounting frame, with at least one side ventilation hole to ensure the main cooling airflow of the cooling fan and the side airflow diversion. During assembly, the fan blades with heat dissipation rings are fixedly mounted on the drive device of the mounting frame, with the heat dissipation ring positioned at the side ventilation hole. When the drive device drives the fan blades to rotate, the heat dissipation ring rotates synchronously in the side ventilation hole. The fan blades guide airflow from one side of the mounting frame to the other, and the heat dissipation ring diverts the airflow in the main ventilation hole through rotation, allowing it to flow out from the side ventilation hole. Through the above structural design, the cooling fan of this application achieves multi-channel airflow cooling, greatly improving the cooling efficiency. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0030] In one embodiment of this utility model, such as Figures 1-4 As shown, a high-efficiency cooling fan is provided, including a mounting frame 10, fan blades 20, and a heat dissipation ring 30. The mounting frame 10 has a main ventilation hole 121 and at least one side ventilation hole 122. The main ventilation hole 121 and the side ventilation hole 122 are connected. A drive device is provided in the main ventilation hole 121 in the mounting frame 10. The fan blades 20 are fixedly mounted on the rotating end of the drive device and are also disposed in the heat dissipation ring 30. The edges of each blade of the fan blades 20 are fixedly connected to the inner surface of the heat dissipation ring 30. The side ventilation hole 122 is disposed opposite to the outer surface of the heat dissipation ring 30. During the rotation of the heat dissipation ring 30, gas is pushed out from the side ventilation hole 122.

[0031] The high-efficiency cooling fan of this utility model is assembled from a mounting frame 10, fan blades 20, and a heat dissipation ring 30. The fan blades 20 and the heat dissipation ring 30 are integrally formed, so that when the fan blades 20 rotate, they drive the heat dissipation ring 30 to rotate simultaneously, achieving simultaneous airflow from the two fan blades 20 and the side airflow from the heat dissipation ring 30. During manufacturing, a main ventilation hole 121 and a side ventilation hole 122 are opened on the mounting frame 10, and at least one side ventilation hole 122 is provided to ensure the main cooling airflow of the cooling fan and the side airflow diversion for the intake air. During assembly, […]. The fan blade 20 with a heat dissipation ring 30 is fixedly mounted on the drive device of the mounting frame 10, and the heat dissipation ring 30 is located at the side ventilation hole 122. When the drive device drives the fan blade 20 to rotate, the heat dissipation ring 30 rotates synchronously in the side ventilation hole 122. The fan blade 20 guides the air to flow from one side of the mounting frame 10 to the other side. The heat dissipation ring 30 diverts the airflow in the main ventilation hole 121 by rotating and flows out from the side ventilation hole 122. Through the above structural arrangement, the cooling fan of this application achieves multi-channel air outlet heat dissipation, which greatly improves the heat dissipation efficiency.

[0032] In another embodiment of this utility model, such as Figures 1-4As shown, the heat dissipation ring 30 includes a collar 31 and several exhaust plates 32. Each blade is fixedly connected to the inner side of the collar 31. Each exhaust plate 32 is arranged at intervals around the outer side of the collar 31. While the collar 31 drives the exhaust plate 32 to rotate, the exhaust plate 32 pushes the gas to move in a fixed direction and is discharged when it passes through the side ventilation hole 122.

[0033] In another embodiment of this utility model, such as Figures 1-4 As shown, the exhaust plate 32 is bent and tilted to one side from the connection end with the collar 31, and the bending direction of the exhaust plate 32 is the same as the bending direction of the blade. The exhaust plate 32 is bent and tilted in the opposite direction of its movement, which can effectively reduce the resistance generated by the air directly in the process of movement.

[0034] In another embodiment of this utility model, such as Figures 3-4 As shown, the top of the exhaust plate 32 is provided with a clearance notch 321, which penetrates the free end side of the exhaust plate 32 to facilitate the assembly of the fan blade 20 and prevent the end of the exhaust plate 32 from obstructing the installation of the fan blade 20 into the mounting frame 10.

[0035] In another embodiment of this utility model, such as Figures 3-4 As shown, the connection surface between the clearance notch 321 and the collar 31 is set as an arc-shaped curved surface. The arc-shaped curved surface can effectively avoid jamming, making the fan blade 20 more smoothly assembled and preventing jamming with the inside of the mounting frame 10.

[0036] In another embodiment of this utility model, such as Figures 1-4 As shown, the free end side of the exhaust plate 32 is set with an arc-shaped curved surface. During the movement of the exhaust plate 32, the gas is guided to flow along the arc-shaped curved surface, which effectively reduces the resistance between the exhaust plate 32 and the gas.

[0037] In another embodiment of this utility model, such as Figures 1-2 As shown, the mounting frame 10 includes a carrier plate 11 and a protective housing 12. The drive device is mounted on the carrier plate 11, and the main ventilation hole 121 is mounted on the protective housing 12. The main ventilation hole 121 is connected to the air inlet on the carrier plate 11. The combined mounting frame 10 of the carrier plate 11 and the protective housing 12 facilitates the assembly of the fan blade 20 and protects the fan blade 20 by wrapping it with the protective housing 12 to prevent the fan blade 20 from falling off.

[0038] In another embodiment of this utility model, such as Figure 2 As shown, a mounting bracket 111 is provided on the carrier plate 11. The mounting bracket 111 is located in the air inlet, and the drive device is fixedly installed on the mounting bracket 111, so that the drive device is located in the center of the main ventilation hole 121.

[0039] In another embodiment of this utility model, such as Figure 2 As shown, the mounting bracket 111 is provided with several cable trays 112 to facilitate the external connection of the drive device's wiring.

[0040] In another embodiment of this utility model, such as Figure 2 As shown, the protective housing 12 is provided with several downwardly extending fasteners (not shown in the figure), each of which is engaged with the carrier plate 11, thereby improving the ease of assembly between the protective housing 12 and the carrier plate 11.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
