Description

Technical Field

[0001] The utility model belongs to the technical field of heat dissipation fans, and in particular relates to a high-efficiency energy-saving heat dissipation fan pressure boosting structure. Background Art

[0002] With the continuous development of electronic equipment, while its performance is constantly improving, the heat dissipation problem has become increasingly prominent. Traditional cooling fans are gradually facing challenges in meeting high heat dissipation requirements. Against this background, the cooling fan boost structure came into being. Electronic equipment such as high-performance computers and servers have internal chips and components that generate a lot of heat when running at high loads, requiring stronger heat dissipation capabilities. However, the wind pressure of ordinary cooling fans is limited, and it is difficult to ensure that air can efficiently pass through complex structures such as cooling fins to take away the heat. The cooling fan boost structure aims to increase the air pressure at the fan outlet by optimizing the fan's aerodynamic design, motor and transmission system, thereby enhancing the air flow capacity.

[0003] However, the current cooling fan boost structure will lead to energy waste. Under the same cooling demand, more electricity is needed, which increases the cost of use and causes unnecessary consumption of energy. Secondly, due to low efficiency, it may not provide sufficient wind pressure and air volume to effectively cool the heat-generating equipment, affecting the performance stability of the equipment and shortening the service life of the equipment. For example, in the server, it may cause the chip to overheat and reduce the frequency. Furthermore, the non-efficient and energy-saving boost structure may generate more heat, further increasing the heat dissipation burden, and may also increase the risk of equipment failure due to poor heat dissipation.

[0024] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will make a detailed description of the specific embodiments of the present utility model in conjunction with the attached drawings of the specification.

[0025] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0026] Secondly, the "one embodiment" or "embodiment" mentioned herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it an individual or selectively mutually exclusive embodiment with other embodiments.

[0027] Embodiment 1

[0028] As Figures 1-5 shown, this is the first embodiment of the present utility model. This embodiment provides an energy-efficient heat dissipation fan supercharging structure, which includes a radiator 1, and a heat dissipation fan mechanism 2 is arranged on the top of the radiator 1;

[0029] The heat dissipation fan mechanism 2 includes a flow guide cover 201, a brushless DC motor 202, supercharging blades 203, supercharging ribs 204, through holes 205, heat dissipation ports 206 and a dust-proof protection net 207. The supercharging ribs 204 are evenly distributed around the bottom of the inner cavity of the flow guide cover 201. The brushless DC motor 202 is adaptively installed at the center of the top of the supercharging ribs 204. The supercharging blades 203 are evenly distributed around the surface of the brushless DC motor 202. The through holes 205 are opened at the top of the flow guide cover 201. The heat dissipation ports 206 are opened at the bottom of the brushless DC motor 202. The dust-proof protection net 207 is located in the inner cavity of the heat dissipation port 206.

[0030] As Figures 1-5 shown, the flow guide cover 201 helps to guide air to enter the heat dissipation fan mechanism 2 more smoothly, reduces the intake resistance, enables the brushless DC motor 202 to utilize energy more efficiently when driving the supercharging blades 203 to rotate, because the special shape of the supercharging blades 203 can make the air flow out evenly, reduce the turbulent flow, and reduce the energy loss. The angle of attack of the supercharging blades 203 at different radii can be maintained within a more appropriate range to adapt to the circumferential speed difference of the air at different radii, enabling the air to flow out of the heat dissipation fan mechanism 2 more evenly, reducing the turbulent flow phenomenon of the air, reducing the energy loss, improving the efficiency of the heat dissipation fan mechanism 2, and helping to achieve a better supercharging effect in a limited space. The brushless DC motor 202 itself has high efficiency, no brush friction and spark discharge loss, can accurately control the rotation speed according to needs, and avoids unnecessary energy consumption. The dust-proof protection net 207 at the heat dissipation port 206 can prevent dust from entering and affecting the performance of the brushless DC motor 202, ensuring the continuous and efficient operation of the brushless DC motor 202. The design of the through holes 205 helps the reasonable flow of air. The combined action of these factors enables the heat dissipation fan mechanism 2 to minimize energy waste while meeting the heat dissipation requirements, achieving the effect of high efficiency and energy saving.

[0031] Embodiment 2

[0032] Refer to Figure 2 andFigure 5 , which is the second embodiment of the present utility model. This embodiment is based on the previous embodiment.

[0033] In this embodiment, plate bodies 3 are fixedly installed around the bottom of the heat dissipation fan mechanism 2. Vibration damping mechanisms 9 are respectively arranged around the bottom of the plate bodies 3. The vibration damping mechanism 9 includes a threaded rod 901, a positioning hole 902, a buffer block 903, a buffer spring 904 and a bottom plate 905. The positioning hole 902 is horizontally opened at one end of the surface of the threaded rod 901. The buffer block 903 is sleeved on the surface of the threaded rod 901 near the top. The buffer spring 904 is sleeved on the surface of the threaded rod 901. The bottom plate 905 is fixedly connected to the end of the threaded rod 901. Heat dissipation fins 7 are arranged in the inner cavity of the radiator 1. Positioning blocks 10 are respectively fixedly installed on the outer sides around the bottom of the plate bodies 3.

[0034] As Figure 2 and Figure 5 shown, the buffer spring 904 in the vibration damping mechanism 9 can effectively buffer the vibration generated during the operation of the heat dissipation fan mechanism 2, reduce the noise that may be caused by the vibration transmitted to other components. The buffer block 903 further enhances the vibration buffering ability, avoiding the vibration directly acting on the threaded rod 901 and the bottom plate 905. The heat dissipation fins 7 can increase the heat dissipation area, improve the heat dissipation efficiency of the radiator 1, and work together with the heat dissipation fan mechanism 2 to ensure the efficient and stable operation of the entire heat dissipation system.

[0035] Embodiment 3

[0036] Referring to Figure 1 , Figure 3 and Figure 4 , which is the third embodiment of the present utility model. This embodiment is based on the previous two embodiments.

[0037] In this embodiment, ventilation grooves 13 are respectively opened on the front and rear sides of the bottom of the radiator 1. A ventilation hole 14 is opened at the center of the bottom of the radiator 1. Heat exchange grooves 15 are respectively opened on both sides of the bottom of the radiator 1 and located on both sides of the ventilation hole 14. Limit side plates 4 are respectively fixedly installed on both sides of the plate body 3. A positioning bracket 5 is sleeved and installed on the surface of the limit side plate 4. Mounting holes 12 are respectively opened on the upper and lower sides of the back surface of the positioning bracket 5. A card slot 11 is opened at the top of the positioning bracket 5. A positioning vertical plate 8 is sleeved and installed on the surface of the positioning bracket 5 and near the front position. A groove 6 is opened at the connection between the positioning vertical plate 8 and the positioning bracket 5.

[0038] As Figure 1 , Figure 3 and Figure 4As shown, the ventilation slots 13 and ventilation holes 14 provide channels for air to enter and exit the radiator 1, enabling cold air to enter smoothly and hot air to be discharged in a timely manner, thereby improving the heat dissipation efficiency. The heat exchange slots 15 further increase the contact area between the bottom of the radiator 1 and the air, enhancing the heat exchange effect. The cooperation between the limit side plates 4 and the positioning brackets 5, through the sleeved installation method, facilitates the connection and positioning of the radiator 1 with other components, enhancing the stability of the entire structure. The mounting holes 12 on the positioning brackets 5 facilitate the installation of the entire device onto other equipment or structures. The designs of the card slots 11 and the grooves 6 contribute to better cooperation with the positioning vertical plates 8, making the connection between components more tight and stable, ensuring that all components of the entire heat dissipation system work together and operate stably and reliably during the working process.

[0039] In summary, the air deflector 201 helps to guide air into the radiator fan mechanism 2 more smoothly, reducing the intake resistance, enabling the brushless DC motor 202 to utilize energy more efficiently when driving the booster blades 203 to rotate. Since the special shape of the booster blades 203 can make the air flow out evenly, reducing turbulence and energy loss. The angle of attack of the booster blades 203 at different radii can be maintained within a relatively appropriate range, adapting to the circumferential speed difference of the air at different radii, enabling the air to flow out of the radiator fan mechanism 2 more evenly, reducing the turbulence phenomenon of the air, lowering the energy loss, improving the efficiency of the radiator fan mechanism 2, and helping to achieve a better boosting effect in a limited space. The brushless DC motor 202 itself has high efficiency, without brush friction and spark losses, and can precisely control the rotation speed according to requirements, avoiding unnecessary energy consumption.
