Description

Technical Field

[0001] This invention relates to the field of cooling fan technology, and in particular to a cooling fan with an auxiliary cooling mechanism. Background Technology

[0002] The heat dissipation efficiency of a cooling fan is one of its core performance indicators. High-efficiency cooling fans are gradually adopting new motor designs, new processes and new materials to improve output efficiency by reducing various types of energy loss. For the heat accumulation problem of large and medium-sized models, a structure with axial and radial ventilation channels in the iron core and an internal fan installed at the rotor end is usually adopted to accelerate the exhaust of hot air and heat transfer, thereby achieving efficient cooling.

[0003] In existing cooling fans, after the internal heat is exhausted by the fan, the flowing air carrying the heat will directly contact the motor casing, causing the temperature on the outside of the motor to rise. This will gradually reduce the heat dissipation effect during motor operation, resulting in continuous heat accumulation on the casing and posing a significant safety risk. Summary of the Invention

[0004] In view of the problems existing in the current cooling fan with an auxiliary heat dissipation mechanism, the present invention is proposed.

[0005] Therefore, the present invention provides a cooling fan with an auxiliary heat dissipation mechanism, the purpose of which is to solve the problems of existing cooling fans where hot air discharged directly contacts the motor housing, causing the temperature to rise, the heat dissipation effect to gradually deteriorate, heat to accumulate continuously, and safety risks to exist.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a cooling fan with an auxiliary heat dissipation mechanism, comprising a cooling fan, a motor unit fixedly installed inside the cooling fan, and a heat dissipation unit fixedly installed on the motor unit; the motor unit comprises a motor body fixedly installed on the cooling fan, and a cooling fan fixedly installed at the output end of the motor body, wherein the cooling fan is rotatably connected to the cooling fan; the heat dissipation unit comprises a protective component fixedly installed at the other end of the motor body, a heat dissipation component fixedly installed inside the protective component, and a water-cooling component rotatably connected inside the heat dissipation component, wherein the water-cooling component is rotatably connected to the protective component.

[0008] As a preferred embodiment of the cooling fan with an auxiliary heat dissipation mechanism described in this invention, a plurality of ventilation openings are provided on the inner wall of the heat dissipation shell.

[0009] As a preferred embodiment of the cooling fan with an auxiliary heat dissipation mechanism described in this invention, the water-cooling assembly includes a heat-absorbing plate rotatably mounted on the motor body, a circulating cooling pipe fixedly mounted on the heat-absorbing plate, and a cooling fan fixedly mounted on the heat-absorbing plate, wherein the cooling fan is fixedly connected to the circulating cooling pipe.

[0010] As a preferred embodiment of the cooling fan with an auxiliary heat dissipation mechanism described in this invention, a cooling component is fixedly installed on the inner wall of the cooling fan, and the cooling component is fixedly connected to the circulating cooling pipe.

[0011] As a preferred embodiment of the cooling fan with an auxiliary heat dissipation mechanism described in this invention, a drive rod is fixedly installed at the other end of the first cooling fan, and a second cooling fan is fixedly installed at the other end of the drive rod, with the drive rod passing through the heat dissipation assembly and rotatably connected.

[0012] As a preferred embodiment of the cooling fan with an auxiliary heat dissipation mechanism described in this invention, the heat dissipation component includes a conical absorption member fixedly installed on the inner wall of the heat dissipation housing, an extrusion member fixedly installed on the heat dissipation housing, and a conical output member fixedly installed on the other end of the extrusion member, wherein the conical output member is fixedly connected to the heat dissipation housing.

[0013] As a preferred embodiment of the cooling fan with an auxiliary heat dissipation mechanism described in this invention, a guide ring is fixedly installed on the outer wall of the drive rod, an enlarged plate is fixedly installed on the guide ring, a baffle is fixedly installed on the enlarged plate, and the enlarged plate and the guide ring are rotatably connected to the conical output component.

[0015] As a preferred embodiment of the cooling fan with an auxiliary heat dissipation mechanism described in this invention, an arc-shaped guide is fixedly installed on the inner wall of the conical output component, and the arc-shaped guide cooperates with the guide plate.

[0016] The beneficial effects of this invention are as follows: This invention achieves basic heat dissipation by driving a cooling fan through the motor body. The other end of the water-cooled component, together with the internal cooling components, circulating cooling pipes, and heat absorption plate, forms a high-efficiency water-cooling circuit, precisely solving the problem of heat generation during long-term motor operation. Moreover, water-cooling has high heat exchange efficiency and is more energy-efficient than simple air cooling. When the water-cooled component dissipates heat, it simultaneously draws in outside air, which is then guided into the heat dissipation component through the protection component. The heat dissipation component converts the horizontal airflow into a high-pressure rotating airflow through pressurization and rotation guidance, impacting the other end of the water-cooled component and driving the first and second cooling fans to rotate synchronously. No additional motor drive is required, which greatly saves driving force and reduces ineffective energy consumption. At the same time, a pressure difference is formed between the front and rear ends, maximizing the heat dissipation and ventilation efficiency. This avoids the problems of temperature rise, heat dissipation attenuation, and heat accumulation caused by the direct contact of hot air with the motor casing by traditional cooling fans, reducing the risk of motor overheating, reducing overheating energy waste, and significantly improving the operational stability, heat dissipation reliability, and service life of the equipment.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Example 1, referring to Figure 1 - Figure 3 The first embodiment of the present invention provides a cooling fan with an auxiliary heat dissipation mechanism. The device includes: a cooling fan 1, a motor unit 2 fixedly installed inside the cooling fan 1 for providing heat dissipation drive; and a heat dissipation unit 3 fixedly installed on the motor unit 2 for dissipating heat from the motor unit 2.

[0031] The motor unit 2 includes a motor body 22 fixedly mounted on the cooling fan 1 for driving the cooling fan 21 to rotate; and a cooling fan 21 fixedly mounted on the output end of the motor body 22, wherein the cooling fan 21 is rotatably connected to the cooling fan 1 and works with the motor body 22 to dissipate heat from the equipment.

[0032] Furthermore, the heat dissipation unit 3 includes a protective component 31 fixedly installed at the other end of the motor body 22 for protecting the entire heat dissipation unit 3; a heat dissipation component 33 fixedly installed inside the protective component 31 for strong ventilation and heat dissipation of the motor body 22; and a water cooling component 32 rotatably connected inside the heat dissipation component 33, and the water cooling component 32 is rotatably connected to the protective component 31 for absorbing the heat of the motor body 22 and performing water cooling heat dissipation.

[0033] During use, firstly, when the motor body 22 drives the cooling fan 21 to work with the cooling fan 1 for normal heat dissipation, the motor body 22 generates heat due to long-term operation. At this time, the water-cooling component 32 at the other end of the motor body 22 starts to rotate to dissipate heat from the motor body 22. At the same time, the cooling component 323 inside the motor body 22 delivers coolant to the circulating cooling pipe 322, which, together with the heat absorption plate 321, performs water-cooling heat dissipation while performing normal heat dissipation from the motor body 22.

[0034] Furthermore, while performing water cooling, the water cooling component 32 draws external air into the protection component 31, causing the air to enter the heat dissipation component 33. The heat dissipation component 33 pressurizes and guides the incoming air, causing the horizontally entering air to rotate and compress, increasing the air pressure. At the same time, the heat dissipation component 33 rotates and guides the pressurized air, allowing the cooling air to directly impact the water cooling component 32 on the other end. This causes the cooling fans 326 and 324 inside the two water cooling components 32 to rotate synchronously. Moreover, the cooling fan 326 gradually drives the cooling fan 324 to rotate, so that the motor body 22 only needs to drive the output end to rotate, while the water cooling component 32 is driven by the heat dissipation component 33 to rotate and dissipate heat rapidly.

[0035] Meanwhile, the water-cooling component 32 generates a pressure difference at both ends, maximizing the heat dissipation and ventilation efficiency. This eliminates the need for additional drive from the motor body 22, saving the driving force of the motor body 22. It also avoids the problems of temperature rise, heat dissipation attenuation, and heat accumulation caused by the direct contact of hot air with the motor housing by the traditional cooling fan. This effectively reduces the safety risk of motor overheating and significantly improves the stability of equipment operation, the reliability of heat dissipation, and service life.

[0036] Example 2, refer to Figure 1 - Figure 6 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the protective component 31 includes a heat dissipation shell 311 fixedly installed on the motor body 22, which provides ventilation protection for the whole; it also includes a connecting base plate 313 fixedly installed on the heat dissipation shell 311, which cooperates with the heat dissipation shell 311 for protection. The inner wall of the heat dissipation shell 311 is provided with multiple sets of ventilation holes 312 for delivering ventilation airflow into the heat dissipation shell 311.

[0037] Compared to Embodiment 1, the water-cooling assembly 32 further includes a heat-absorbing plate 321 rotatably mounted on the motor body 22 for absorbing the heat generated by the motor body 22; a circulating cooling pipe 322 fixedly mounted on the heat-absorbing plate 321 for cooling the heat absorbed by the heat-absorbing plate 321; and a cooling fan 324 fixedly mounted on the heat-absorbing plate 321, wherein the cooling fan 324 is fixedly connected to the circulating cooling pipe 322 and works in conjunction with the circulating cooling pipe 322 to dissipate heat.

[0038] Furthermore, a cooling component 323 is fixedly installed on the inner wall of the cooling fan 324, and the cooling component 323 is fixedly connected to the circulating cooling pipe 322 for supplying coolant to the circulating cooling pipe 322.

[0039] Furthermore, a drive rod 325 is fixedly installed at the other end of the cooling fan 324. The drive rod is connected to the cooling fan 326. The other end of the drive rod 325 is fixedly installed with the cooling fan 326. The drive rod 325 passes through the heat dissipation assembly 33 and is rotatably connected to it. Together with the cooling fan 324 and the circulating cooling pipe 322, it achieves water cooling and air cooling.

[0040] During operation, firstly, when the motor body 22 generates a large amount of heat during normal operation, the heat absorption plate 321 begins to absorb the heat generated by the motor body 22. At the same time, the cooling component 323 delivers coolant to the circulating cooling pipe 322, allowing the circulating cooling pipe 322 to begin water-cooling the heat absorbed by the heat absorption plate 321. Simultaneously, the cooling fan 324 also begins to rotate, providing initial ventilation and heat dissipation. With the assistance of the vent 312, external air is drawn into the protection component 31 and then blown by the cooling fan 324 onto the heat dissipation component 33. The heat dissipation component 33 pressurizes and guides the incoming air, increasing the air speed. The increased pressure impacts the cooling fan 326, causing it to rotate. This causes the cooling fans 326 and 324 inside the water-cooling components 32 on both sides to rotate synchronously, creating a pressure difference at both ends. This optimizes the cooling and ventilation efficiency. Furthermore, the cooling fan 326 gradually drives the cooling fan 324 to rotate, so the motor body 22 only needs to drive the output end to rotate. The cooling fan 324 is then driven by the heat dissipation component 33 to rotate rapidly for heat dissipation, thereby enhancing the heat dissipation effect, effectively reducing the safety risk of motor overheating, and significantly improving the stability of equipment operation, the reliability of heat dissipation, and the service life.

[0041] The remaining structure is the same as that in Example 1.

[0042] Example 3, referring to Figure 1 - Figure 10This is the third embodiment of the present invention, which differs from the second embodiment in that: the heat dissipation assembly 33 includes a conical absorption member 331 fixedly installed on the inner wall of the heat dissipation shell 311, which is used to collect and transport air over a wide area; it also includes an extrusion member 332 fixedly installed on the heat dissipation shell 311, which is used to initially pressurize and rotate the collected air; and a conical output member 333 fixedly installed on the other end of the extrusion member 332, which is fixedly connected to the heat dissipation shell 311 and is used to output the air after being extruded and guided.

[0043] Compared to Embodiment 2, a guide ring 335 is further fixedly installed on the outer wall of the drive rod 325 for circumferential guidance of the air after the extrusion 332 is reinforced. An enlarger plate 336 is fixedly installed on the guide ring 335 for increasing the air flow. A wind baffle 338 is fixedly installed on the enlarger plate 336. The enlarger plate 336 and the guide ring 335 are rotatably connected to the conical output member 333, and the conical output member 333 and the enlarger plate 336 work together to guide and convey the air.

[0044] Furthermore, a guide plate 334 is fixedly installed on the inner wall of the extruder 332 to provide initial rotational guidance for the air passing through the extruder 332. An arc-shaped guide 337 is fixedly installed on the inner wall of the conical output part 333, and the arc-shaped guide 337 cooperates with the guide plate 334 to rotate and guide the air distributed and guided by the guide ring 335, so that the air forms a strong rotating wind after being output.

[0045] During use, firstly, when the motor body 22 is initially cooled and ventilated by the water-cooling component 32, the water-cooling component 32 draws the outside air into the protection component 31 and blows the air toward the conical absorber 331. The conical absorber 331 delivers a large amount of air to the extrusion component 332. At the same time, as the extrusion component 332 rapidly shrinks, the large amount of air flowing from the conical absorber 331 into the extrusion component 332 is pressurized, and the wind speed begins to increase.

[0046] Meanwhile, the airflow is initially rotated and guided by the guide plate 334 on the inner wall of the extruder 332, and then the airflow is delivered to the guide ring 335. Guided by the guide ring 335, the airflow begins to move towards the outer wall of the conical output part 333. Under the limiting action of the arc-shaped guide 337 on the outer wall of the guide ring 335, the airflow speed reaches its maximum. At the same time, the airflow forms a rotating wind and then directly impacts the second cooling fan 326, causing the second cooling fan 326 to start rotating. This also creates a wind pressure difference between the two ends of the second cooling fan 326 and the first cooling fan 324, allowing the airflow passing through the extruder 332 to be quickly accelerated, thus increasing the ventilation speed inside the heat dissipation shell 311. Together with the water cooling component 32, this quickly dissipates heat from the motor body 22.

[0047] When the second cooling fan 326 rotates, it also drives the drive rod 325 to rotate together with the first cooling fan 324. This means that the motor body 22 does not need to drive the first cooling fan 324, but only needs to drive the output end. This enhances the heat dissipation effect of the motor body 22, thereby maximizing the heat dissipation and ventilation efficiency. It avoids the problems of temperature rise, heat dissipation attenuation, and heat accumulation caused by the direct contact of hot air with the motor casing by the traditional cooling fan. This reduces the risk of motor overheating, reduces the waste of energy due to overheating, and greatly improves the stability of equipment operation, the reliability of heat dissipation, and the service life.

[0048] The remaining structure is the same as that in Example 2.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
