[0002] Currently, electronic equipment enclosures need to be designed as sealed enclosures to meet protection requirements. Since these enclosures contain heat-generating electronic components, they require cooling systems to ensure normal operation. However, current cooling methods for sealed enclosures typically involve installing turbulence fans inside the enclosure. These fans usually consume electrical energy, resulting in high operating costs for the cooling systems.

[0003] In conclusion, how to solve the problem of high operating costs of heat dissipation systems in enclosed chassis has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, this application provides a turbulence device and a heat dissipation system for a sealed chassis to solve the problem of high operating costs of heat dissipation systems for sealed chassis.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A flow-dissipating device, applied to a sealed enclosure, comprising:

[0007] The fan blades are rotatably mounted outside the sealed enclosure and can rotate by receiving external wind energy.

[0008] The turbulence fan blades are rotatably mounted inside the sealed enclosure;

[0009] The transmission mechanism has an input end and an output end. The input end is connected to the fan blade, and the output end is connected to the deflector blade, so that the rotation of the fan blade can drive the deflector blade to rotate.

[0010] In some embodiments of this application, the input end is configured as an input shaft, and the fan blade is fixedly disposed on the input shaft.

[0011] In some embodiments of this application, the output terminal is configured as an output shaft rotatably disposed on the sealed chassis, and the turbulence fan blades are disposed on the output shaft and can rotate with the output shaft.

[0012] In some embodiments of this application, the transmission mechanism includes an input shaft, an output shaft, and a transmission part connected between the input shaft and the output shaft. The fan blade is disposed on the input shaft and can drive the input shaft to rotate. The deflector fan blade is disposed on the output shaft and can rotate with the output shaft.

[0013] In some embodiments of this application, the transmission unit is configured as a transmission shaft rotatably disposed in the sealed housing, the transmission shaft being connected to the input shaft via a first bevel gear set, and the transmission shaft being connected to the output shaft via a second bevel gear set.

[0014] In some embodiments of this application, a swing bracket is also included, which can freely swing about the axis of the transmission shaft, and the input shaft is rotatably disposed on the swing bracket.

[0015] In some embodiments of this application, the swing bracket includes a swing body and a first bushing and a second bushing disposed on the swing body. The axis of the first bushing and the axis of the second bushing are coplanar and arranged perpendicularly. The input shaft is disposed on the first bushing in a rotatable manner, and the second bushing is disposed on the transmission shaft or the sealed housing in a rotatable manner around the axis of the transmission shaft.

[0016] In some embodiments of this application, an air regulating plate is further provided on the swing bracket, the surface of the air regulating plate being parallel or coplanar with a preset plane, wherein the preset plane is the coplanar plane containing the axis of the first bushing and the axis of the second bushing.

[0017] In some embodiments of this application, the lower end of the swing bracket is higher than the top surface of the sealed chassis by a predetermined distance.

[0018] In some embodiments of this application, a mounting base is provided on the sealed enclosure, and the drive shaft is mounted on the mounting base via a drive bearing; wherein the mounting base is located on the outer side wall or the inner side wall of the sealed enclosure.

[0019] To address the high operating costs of heat dissipation systems in sealed enclosures, this application provides a flow-dissipating device comprising a fan blade, a deflector blade, and a transmission mechanism. The fan blade is rotatably mounted outside the sealed enclosure and can rotate by receiving external wind energy. The deflector blade is rotatably mounted inside the sealed enclosure. The transmission mechanism has an input end and an output end; the input end is driven by the fan blade, and the output end is driven by the deflector blade, so that the rotation of the fan blade drives the rotation of the deflector blade. When applied to a sealed enclosure, this flow-dissipating device utilizes the fan blade to receive external wind energy from the enclosure and rotate. Since the input end of the transmission mechanism is driven by the fan blade, and the output end is driven by the deflector blade, and the deflector blade is rotatably mounted inside the sealed enclosure, the rotation of the fan blade drives the rotation of the deflector blade, thereby enabling the deflector blade to turbulently dissipate heat from the airflow within the sealed enclosure. This flow-dissipating device operates solely on external wind energy and does not consume electrical energy, significantly reducing the operating costs of the heat dissipation system for sealed enclosures.

[0053] The core of this application is to provide a turbulence device and a heat dissipation system for a sealed chassis, so as to solve the problem of high operating costs of heat dissipation systems for sealed chassis.

[0054] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0055] In existing technologies, electronic device enclosures often have protection level requirements, necessitating a sealed enclosure design. Furthermore, since these sealed enclosures contain heat-generating electronic components, a cooling system is required to meet the operational needs of the electronic equipment. Currently, cooling methods for sealed enclosures generally fall into three categories: The first method involves a sealed enclosure without a turbulent fan, relying entirely on self-cooling. The second method includes a turbulent fan inside the enclosure. The internal circulating airflow generated by the turbulent fan allows heat generated by the electronic components to better contact the inner wall of the enclosure, thus dissipating heat to the outside atmosphere through the enclosure. The third method involves a sealed enclosure with a heat exchanger. An internal turbulent fan drives airflow within the internal circulating duct through the portion of the heat exchanger inside the enclosure. An external cooling fan dissipates the heat conducted by the heat exchanger into the atmosphere, achieving efficient heat dissipation. Of the three heat dissipation methods for sealed chassis mentioned above, the first method, although inexpensive, has poor heat dissipation effect and lacks internal turbulence, which is detrimental to the lifespan of electronic components. The second and third methods both have turbulence fans, however, the operation of turbulence fans usually consumes electrical energy, and the lifespan of turbulence fans is limited, requiring replacement and maintenance when damaged. Therefore, both the second and third methods suffer from high operating costs for the heat dissipation system.

[0056] Based on this, refer to Figure 1As shown, this application provides a flow-disrupting device applied to a sealed enclosure 2 to reduce the operating cost of the enclosure 2's heat dissipation system. The flow-disrupting device specifically includes a fan blade 11, a deflector fan blade 12, and a transmission mechanism 13. The fan blade 11 is rotatably mounted outside the sealed enclosure 2 and can rotate by receiving external wind energy. The working principle of the fan blade 11 is similar to a windmill in a child's toy, rotating under wind force. The specific structural form of the fan blade 11 is not limited as long as it can receive wind energy and rotate. For example, the rotation structure of the fan blade 11 can be designed to rotate under wind force in the direction of the rotation axis, or it can be designed to rotate radially under wind force. Furthermore, external wind energy refers to the external airflow of the sealed enclosure 2, specifically, external... The airflow in the atmosphere can also be the airflow from the outlet of a device, without specific limitations. The turbulence fan blade 12 is rotatably mounted inside the sealed casing 2. The rotation of the turbulence fan blade 12 can turbulentize the airflow inside the sealed casing 2. On the one hand, it can make the heat distribution of the airflow inside the sealed casing 2 more uniform. On the other hand, it can make the heat generated by the electronic components inside the sealed casing 2 better contact the inner wall of the outer shell of the sealed casing 2, thereby dissipating heat to the outside atmosphere through the outer shell. The transmission mechanism 13 has an input end and an output end. The input end is connected to the fan blade 11, and the output end is connected to the turbulence fan blade 12. Through the transmission mechanism 13, the rotational kinetic energy of the fan blade 11 can be transmitted to the turbulence fan blade 12, so that the rotation of the fan blade 11 can drive the turbulence fan blade 12 to rotate.

[0057] When applied to the sealed enclosure 2, this airflow turbulence device utilizes the fan blades 11 to receive external wind energy and rotate. Since the input end of the transmission mechanism 13 is connected to the fan blades 11 and the output end is connected to the turbulence fan blades 12, and the turbulence fan blades 12 are rotatably mounted inside the sealed enclosure 2, the rotation of the fan blades 11 drives the turbulence fan blades 12 to rotate, thereby enabling the turbulence fan blades 12 to turbulently dissipate heat from the airflow within the sealed enclosure 2. The operation of this airflow turbulence device relies solely on external wind energy and does not consume electrical energy, significantly reducing the operating cost of the cooling system of the sealed enclosure 2.

[0058] In some specific implementation plans, refer to Figure 1 and Figure 2As shown, the input end can be specifically constructed as an input shaft 131, with the fan blade 11 fixedly mounted on it. The fan blade 11 can be detachably mounted on the input shaft 131, for example, by a key connection, but not limited to that; or it can be non-detachably mounted on the input shaft 131, for example, by welding, but not limited to that. No specific limitations are made here. Specifically, the fan blade 11 rotates under the influence of external wind, which in turn drives the input shaft 131 to rotate, and then transmits the rotational kinetic energy to the output end of the transmission mechanism 13 through the input shaft 131. By designing the input end as an input shaft 131, the fan blade 11 can be directly fixed to the input shaft 131, making the installation and arrangement of the fan blade 11 more convenient and reducing the risk of interference between the fan blade 11 and the transmission mechanism 13. It is understandable that the input end design as an input shaft 131 is merely an example of an embodiment in this application. In actual applications, it can be designed with other structural forms. For example, the fan blade 11 can be mounted on the outside of the sealed casing 2 via a mounting bracket, with a transmission sprocket or transmission pulley located at the rotation center of the fan blade 11, and the input end being a chain fitted onto the transmission sprocket or a belt onto the transmission pulley. Alternatively, a first transmission gear can be located at the rotation center of the fan blade 11, and the input end can be a second transmission gear meshing with the first transmission gear. In actual applications, the configuration can be selected according to actual needs, and no further specific limitations are made here.

[0059] In some other specific implementation schemes, refer to Figure 1 and Figure 5As shown, the output end can be specifically configured as an output shaft 132 rotatably mounted on the sealed casing 2. The turbulence fan blade 12 is mounted on the output shaft 132 and can rotate with it. Specifically, the turbulence fan blade 12 can be detachably fixed to the output shaft 132, for example, by a key connection, but not limited to this; or it can be non-detachably fixed to the output shaft 132, for example, by welding, but not limited to this. Specifically, the fan blade 11 rotates under the influence of external wind, and the rotational kinetic energy is transmitted to the output shaft 132 through the transmission mechanism 13. The rotation of the output shaft 132 drives the turbulence fan blade 12 to rotate, thereby achieving turbulence-induced heat dissipation within the sealed casing 2. By designing this structure, the turbulence fan blade 12 can be directly fixed to the output shaft 132, making the installation and arrangement of the turbulence fan blade 12 more convenient and reducing the risk of interference between the turbulence fan blade 12 and the transmission mechanism 13. It is understandable that the output end design as an output shaft 132 is merely an example of an embodiment in this application. In actual applications, other structural forms can also be designed. For example, the turbulence fan blade 12 can be mounted in a sealed housing 2 using a mounting bracket, with a transmission sprocket or transmission pulley located at the rotation center of the turbulence fan blade 12, and the output end being a chain fitted onto the transmission sprocket or a belt onto the transmission pulley. Alternatively, a third transmission gear can be located at the rotation center of the turbulence fan blade 12, and the output end can be a fourth transmission gear meshing with the first transmission gear. In actual applications, the configuration can be selected according to actual needs, and no further specific limitations are made here.

[0060] In some specific implementation plans, refer to Figure 1 , Figure 2 and Figure 5 As shown, the aforementioned transmission mechanism 13 may specifically include an input shaft 131, an output shaft 132, and a transmission part 133 connecting the input shaft 131 and the output shaft 132. The fan blade 11 is disposed on the input shaft 131 and can drive the input shaft 131 to rotate. The deflector fan blade 12 is disposed on the output shaft 132 and can rotate with the output shaft 132. The transmission part 133 is mainly used to transmit the rotational torque of the input shaft 131 to the output shaft 132, and its specific design can be as follows: Figure 3 The structure of the transmission shaft 133' shown can also be a gear assembly structure or a chain drive structure, as long as the torque transmission between the input shaft 131 and the output shaft 132 can be guaranteed. No further specific limitations are made here.

[0061] In a further implementation plan, refer to Figures 1-3 and Figure 5 , combined Figure 6As shown, the aforementioned transmission unit 133 can be specifically configured as a transmission shaft 133' rotatably mounted on the sealed housing 2. Specifically, a mounting base 3 can be provided on the sealed housing 2, and the transmission shaft 133' is mounted on the mounting base 3. The mounting base 3 can be designed on the outer wall of the sealed housing 2, in which case the transmission shaft 133' is located on the outer side of the sealed housing 2, or it can be designed on the inner side of the sealed housing 2, in which case part of the transmission shaft 133' is located on the inner side of the sealed housing 2 and part of it is located on the outer side of the sealed housing 2. In order to ensure that the transmission shaft 133' can rotate freely on the mounting base 3, the transmission shaft 133' can be mounted on the mounting base 3 by a transmission shaft 133' bearing. In order to allow the transmission shaft 133' to rotate normally while keeping the axial direction of the transmission shaft 133' from displacement, the transmission shaft 133' bearing can be specifically selected as a radial thrust bearing. A force bearing is used; the transmission shaft 133' is connected to the input shaft 131 via a first bevel gear set 134. Specifically, the first bevel gear set 134 may include a first A gear 134a mounted on the input shaft 131 and a first B gear 134b mounted on the transmission shaft 133'. The transmission shaft 133' is connected to the output shaft 132 via a second bevel gear set 135. The output shaft 132 may be mounted on the wall of the sealed housing 2 via a bearing 4. This bearing 4 may be a sealed bearing to prevent rainwater from entering the sealed housing 2. The second bevel gear set 135 may include a second A gear 135a mounted on the output shaft 132 and a second B gear 135b mounted on the transmission shaft 133'. By designing the transmission part 133 as a transmission shaft 133' and achieving transmission connections with the input shaft 131 and the output shaft 132 via the first bevel gear set 134 and the second bevel gear set 135 respectively, the torque transmission of the entire transmission mechanism 13 is made more stable and reliable.

[0062] It is also worth mentioning that the transmission unit 133 is not limited to the structure of a transmission shaft 133'. In practical applications, it can also be designed into other transmission structures, such as chain drive, belt drive or gear drive, etc., without specific limitations.

[0063] In a further implementation plan, refer to Figure 1 Combination Figure 7 and Figure 8As shown, the aforementioned turbulence device may further include a swing bracket 14, which can freely swing around the axis of the drive shaft 133', and the input shaft 131 is rotatably mounted on the swing bracket 14. By setting the swing bracket 14, when the airflow blows towards the fan blade 11 fixed on the input shaft 131, under the blowing action of the wind force on the fan blade 11, the swing bracket 14 can adaptively swing a certain angle until the axis of the input shaft 131 is aligned with the wind direction or arranged in a position that conforms to the wind direction, ultimately enabling the fan blade 11 to reach the optimal position for receiving wind energy, that is, the fan blade 11 can continuously capture the optimal wind direction as the wind direction changes, and receive more wind energy, for example, when the wind direction changes from... Figure 1 The directional change shown is Figure 7 and Figure 8 When the wind direction is as shown, under the action of the swing bracket 14, the axial direction of the input shaft 131 can be changed to be consistent with the wind direction or arranged in accordance with the wind direction, so that the fan blade 11 can obtain more wind energy under the ventilation wind force level.

[0064] Specifically, refer to Figure 1 , Figure 7 and Figure 8 , combined Figure 4 As shown, the aforementioned swing bracket 14 may specifically include a swing body 141 and a first bushing 142 and a second bushing 143 disposed on the swing body 141. The axis of the first bushing 142 and the axis of the second bushing 143 are coplanar and arranged perpendicularly. The input shaft 131 is rotatably disposed on the first bushing 142. The second bushing 143 may be disposed on the transmission shaft 133' and can rotate freely around the axis of the transmission shaft 133', or the second bushing 143 may be disposed on the sealed housing 2 and can rotate freely around the axis of the transmission shaft 133'. In the latter case, a rotating seat coaxially arranged with the transmission shaft 133' may be disposed on the sealed housing 2, and the second bushing 143 may be rotatably disposed on the rotating seat. By designing the swing bracket 14 with the above-described structure, since the first bushing 142 and the second bushing 143 are coplanar and arranged perpendicularly, the swing bracket 14 has a better swing effect.

[0065] In a further implementation plan, refer to Figure 4 Combination Figure 7 and Figure 8As shown, the aforementioned turbulence device may further include a wind deflector 144 disposed on the swing bracket 14. Specifically, the wind deflector 144 can be designed as a planar plate structure. It can be disposed on the swing body 141 or on the second bushing 143. The surface of the wind deflector 144 is parallel or coplanar with a preset plane, where the preset plane is the coplanar plane containing the axes of the first bushing 142 and the second bushing 143. By designing this wind deflector 144, when the external airflow direction is not parallel to the wind deflector 144, the wind deflector 144 is driven by the wind force to swing the swing bracket 14 around the axis of the transmission shaft 133'. The final stable state is that the plane containing the wind deflector 144 is parallel to the wind direction. The wind deflector 144 is equivalent to a rigid flag. Under the action of this structure, the swing bracket 14 swings more smoothly with the wind direction, and the fan blades 11 can more stably capture the optimal wind direction and receive the most wind energy.

[0066] It should be noted that, referring to Figure 4 As shown, the above-mentioned swing body 141, first bushing 142, second bushing 143 and air regulating plate 144 can be designed as an integral structure, such as integral casting, or they can be designed as a separate fixed connection structure, such as welding.

[0067] In some other specific implementation schemes, refer to Figure 1 , Figure 7 and Figure 8 As shown, the aforementioned drive shaft 133' can be specifically designed to be arranged vertically, with the lower end of the swing bracket 14 extending a predetermined distance above the top surface of the sealed housing 2. In this case, the input shaft 131 and the fan blade 11 on the input shaft 131, both mounted on the swing bracket 14, are located at the top of the sealed housing 2. The top of the sealed housing 2, compared to its sides, has no obstructions, allowing for better wind energy reception. It is understood that designing the fan blade 11 at the top of the sealed housing 2 is merely an example of this embodiment. In practical applications, it can also be designed on the circumferential sidewalls of the sealed housing 2, excluding the door, as long as it can receive wind energy and rotate.

[0068] On the other hand, this application also provides a heat dissipation system for a sealed chassis, including a heat dissipation device, which at least includes the airflow turbulence device described in any of the above-mentioned solutions. Since the aforementioned airflow turbulence device has the above-mentioned technical effects, the heat dissipation system of the sealed chassis with this airflow turbulence device should also have corresponding technical effects, which will not be elaborated further here.

[0069] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
