Description

Technical Field

[0001] This application relates to the field of energy storage device technologies, and in particular, to a fan assembly and a device housing. Background Art

[0002] In modern energy storage systems and server devices, the role of fans is indispensable. These devices usually need to use multiple fans to keep the temperature and heat dissipation within a controllable range to ensure the stability and performance of the devices. Usually, multiple fans are placed in parallel on a bracket to provide sufficient cooling effect.

[0003] When one or more of the fans fail, they need to be replaced and maintained. To simplify the maintenance process, multiple fans are usually installed on a bracket or connected together by hinges, and then the entire fan system is placed in a guide rail. This design enables the entire fan system to be easily withdrawn or inserted from the device for maintenance operations.

[0004] However, this design has some problems. First, the guide rail needs to wrap around the front and rear sides of the fan bracket, and the fan bracket itself also needs to be packaged on the front and rear sides of the fan, resulting in a large device space occupied by the installation of the fan system. Second, due to this design, the distance between the air guiding structure designed on the device behind the fan and the fan is enlarged, resulting in a gap exceeding the specified value, thereby causing a large amount of air leakage and reducing the heat dissipation performance of the device. Summary of the Utility Model

[0005] In order to improve the problems that the installation of the fan system occupies a large device space and is prone to air leakage, this application provides a fan assembly and a device housing.

[0006] The fan assembly and device housing provided by this application adopt the following technical solutions:

[0007] A fan assembly includes a guide rail frame, multiple fans, and multiple brackets that are rotatably connected to each other. The fans correspond to the brackets one by one and are accommodated in the brackets, and the brackets are accommodated in the guide rail frame. The guide rail frame is provided with guide and limit strips that are arranged along the length direction, and the brackets slide in the guide rail frame along the guide and limit strips, and the brackets are fixedly connected to the guide and limit strips.

[0008] By adopting the above technical solution, when in use, each fan is paired with its corresponding bracket, and the fan is placed in the bracket, and a plurality of interconnected brackets are slid along the guide limit strips in the guide rail frame, and the brackets are fixed in contact with the guide limit strips, thereby realizing the installation and pulling of the fan assembly; in this process, the setting of the guide limit strips can effectively limit the movement range of the bracket in the guide rail frame, thereby realizing the limiting and guiding of the bracket; since the connection between the bracket and the fan is restricted in the guide rail frame, this design can reduce the space occupied by the fan assembly in the thickness direction, so that the fan can be set closer to the wind guide structure of the equipment, and the wind guide structure can more effectively guide the wind flow, thereby improving the heat dissipation effect of the equipment.

[0009] In a specific feasible implementation scheme, the bracket includes a first plate and a second plate covering the fan in the thickness direction and a baffle covering the fan in the length direction, and the first plate and the second plate are arranged on both sides of the baffle; the guide rail frame includes a third plate and a fourth plate covering the bracket in the thickness direction and a mounting plate covering the bracket in the length direction, and the third plate and the fourth plate are arranged on both sides of the mounting plate; the first plate is in conflict with the third plate, the second plate is in conflict with the fourth plate, the guide limit strip is arranged on the fourth plate, and the second plate is fixedly connected to the guide limit strip.

[0010] By adopting the above technical solution and utilizing the above design, the first plate and the second plate in the bracket are arranged on the upper and lower sides of the fan instead of on the front and rear sides of the fan, and the third plate and the fourth plate in the guide rail frame are arranged on the upper and lower sides of the bracket instead of on the front and rear sides of the bracket, thereby avoiding all-round covering of the fan and the bracket in the thickness direction and reducing the space occupied by the fan assembly in this direction; and in the design, the width of the first plate is greater than the width of the third plate, and the width of the fourth plate is greater than the width of the second plate. Such an arrangement causes the bracket and the guide rail frame to be misaligned in the thickness direction, thereby achieving the purpose of at least partially extending the bracket and the fan out of the guide rail frame, further saving the thickness of the overall structure in the thickness direction and saving occupied space.

[0011] In a specific possible implementation manner, the first plates of adjacent brackets are connected by a hinge, the first plates extend out of the third plate, and a guide connection block is provided on one side of the first plate extending out of the third plate.

[0012] By adopting the above technical solution, a guide connecting block is designed on one side of the first plate extending out from the third plate, and the guide connecting block serves as a guide structure for subsequent connection with the device. By setting the connection structure on the first plate of the bracket instead of setting it on the guide rail frame, the space occupied by the fan assembly can be reduced while realizing the subsequent connection guide between the fan assembly and the device, thereby solving the problem of insufficient space.

[0013] In a specific feasible implementation, a guiding arc surface is provided at the end of the guiding connection block.

[0014] By adopting the above technical solution, during the actual installation process, the design of the guiding arc surface enables the guiding connection block to pass more smoothly through the connection part of the device during installation, can guide the connection block to move along the expected path, ensure its correct alignment to the connection point of the device, thereby avoiding possible deviations or misalignments during installation, and the guiding arc surface also helps to reduce the collision and friction between the connection block and the device, reducing the risk of damage that may be caused by the installation process.

[0015] In a specific feasible implementation, a stepped portion is provided on the side of the fourth plate away from the mounting plate, and the guiding limiting strip is located on the side of the fourth plate close to the stepped portion.

[0016] By adopting the above technical solution, with the setting of the stepped portion, the stepped portion can serve as a support point, providing additional support and installation space, ensuring that the device or structure remains stable and balanced after installation, can make the most of the available space within a limited space, increase the space utilization efficiency, and provide convenience for installing other components or accessories, such as accommodating the laying of the fan wiring harness, while enhancing the strength and stability of the entire structure.

[0017] In a specific feasible implementation, a guiding inclined surface is provided at the end of the guiding limiting strip.

[0018] By adopting the above technical solution, with the design of the guiding inclined surface, the guiding limiting strip can guide the bracket to be installed on the guide rail frame more smoothly, and can ensure that the bracket maintains the correct direction and position during the installation process, improving the installation efficiency and the reliability of the connection.

[0019] In a specific feasible implementation, the first or last bracket is provided with a handle structure.

[0020] By adopting the above technical solution, with the design of the handle structure, users can easily manipulate the bracket and the fan, install them on the guide rail frame without additional tools. Users can directly hold the handle and accurately push the bracket into or pull it out of the guide rail bracket, thus simplifying the installation process; when maintenance or replacement of the fan or bracket is required, users only need to easily hold the handle and take it out of the guide rail frame without worrying about inconvenient operation or damaging the device; the design of the handle structure provides convenience for the installation and maintenance of the fan and the bracket, improving the operation convenience, safety and user experience.

[0021] An equipment housing, the equipment housing includes a wind guiding structure and the fan assembly as described above, the equipment housing is provided with a receiving groove, the fan assembly slides and abuts within the receiving groove and is fixed within the receiving groove, the wind guiding structure is arranged within the receiving groove, and the wind guiding structure is arranged along the height direction and abuts against the guide rail frame.

[0022] By adopting the above technical solution, the equipment housing of the present application utilizes the fan assembly of the present application. Since the fan assembly is restricted within the guide rail frame and at least partially extends out of the guide rail frame, this design can reduce the space occupied by the fan assembly in the thickness direction, shorten the distance between the fan assembly and the wind guiding structure of the equipment housing. By combining the fan assembly with the wind guiding structure of the equipment housing, the wind guiding gap can be reduced, the air leakage problem can be improved, and it is ensured that more of the air flow blown by the fan passes through the wind guiding structure, thereby improving the heat dissipation performance of the equipment.

[0023] In a specific feasible implementation, the receiving groove is provided with a communicating guiding groove, and the guiding connection block of the bracket slides and abuts within the guiding groove and is fixed within the guiding groove.

[0024] By adopting the above technical solution, during the installation process of the fan assembly and the equipment housing, by utilizing the design of the guiding groove within the receiving groove, the guiding connection block of the bracket can accurately align with the guiding groove, thereby ensuring that the fan assembly can be correctly positioned and fixed within the receiving groove of the equipment housing, thus improving the installation efficiency and product quality.

[0025] In a specific feasible implementation, the handle structure abuts against the outer wall of the equipment housing, the wind guiding structure abuts against the stepped portion, and the guide rail frame abuts against the receiving groove; the handle structure and the equipment housing, the wind guiding structure and the stepped portion, and the guide rail frame and the receiving groove are all fixed by screws.

[0026] By adopting the above technical solution, the handle structure, the air guiding structure, the guide rail frame and the equipment shell are fixed by screws, ensuring the tight connection and stability between them. This fixing method makes the equipment not easily affected by external vibration or impact during operation; the contact between the guide rail frame and the accommodating groove can ensure the stable installation of the fan assembly on the equipment shell, and the contact between the air guiding structure and the stepped part enables the air guiding structure to more stably guide the air flow generated by the guiding fan assembly to the equipment shell, and the contact between the handle structure and the outer wall of the equipment shell helps to provide additional support and stability; and in the design of this application, the guide rail frame and the bracket are respectively fixed to the equipment shell, which is convenient for the subsequent maintenance of the fan. When it is necessary to maintain or replace the fan in the bracket, only the connection between the bracket and the equipment shell needs to be released to replace the fan, without having to remove the equipment shell together with all the internal and external parts. This can save time and manpower and reduce the interference with the equipment during the maintenance process, making the maintenance process more efficient and convenient.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. For the fan assembly of this application, by designing that the first plate and the second plate in the bracket are arranged on the upper and lower sides of the fan instead of the front and rear sides of the fan, and the third plate and the fourth plate in the guide rail frame are arranged on the upper and lower sides of the bracket instead of the front and rear sides of the bracket, it avoids the full - scale wrapping of the fan and the bracket in the thickness direction, reducing the space occupied by the fan assembly in this direction; and the setting of the guiding and limiting strips can effectively limit the moving range of the bracket in the guide rail frame, realizing the limiting and guiding of the bracket, and at least part of the bracket and the fan extend out of the guide rail frame. This design can further reduce the space occupied by the fan assembly in the thickness direction, enabling the fan to be arranged closer to the air guiding structure of the equipment, so that the air guiding structure can more effectively guide the air flow, thereby improving the heat dissipation effect of the equipment.

[0029] 2. For the equipment shell of this application, by using the design of the fan assembly, since the fan assembly is restricted in the guide rail frame and at least part of it extends out of the guide rail frame, this design can reduce the space occupied by the fan assembly in the thickness direction, shorten the distance from the fan assembly to the air guiding structure of the equipment shell, and by combining the fan assembly with the air guiding structure of the equipment shell, the air guiding gap between the fan assembly and the equipment shell can be reduced, improving the air leakage problem, ensuring that more of the air flow blown by the fan passes through the air guiding structure, thereby improving the heat dissipation performance of the equipment.

[0036] The following further describes the present application in detail Figures 1-5 with reference to the attached drawings.

[0037] Embodiment 1

[0038] Please refer to Figures 1-3 as shown in the figure. In the embodiment of the present application, a fan assembly is disclosed. In this embodiment, the fan assembly 1 includes but is not limited to a heat dissipation auxiliary device applied to energy storage equipment;

[0039] The fan assembly 1 includes a guide rail frame 2, a plurality of fans 3, and a plurality of brackets 4 that are rotatably connected to each other. In this embodiment, the plurality of brackets 4 include but are not limited to being rotatably connected through hinges. The fans 3 correspond to the brackets 4 one by one, and the fans 3 are accommodated in the brackets 4. In this embodiment, the fans 3 and the brackets 4 include but are not limited to being fixedly connected by screws. The plurality of interconnected brackets 4 are accommodated in the guide rail frame 2;

[0040] The first or last bracket 4 is provided with a handle structure 8. In this embodiment, the handle structure 8 includes a fixing plate 81 provided on the bracket 4 and a handle 82 provided on the fixing plate 81. The fixing plate 81 is provided with a fixing hole 811 for installation. The design of the handle structure 8 enables the operator to easily manipulate the bracket 4 and the fan 3 and install them on the guide rail bracket 2 without additional tools. The user can directly hold the handle 82 and accurately push or pull the bracket 4 into or out of the guide rail bracket, thus simplifying the installation process. When maintenance or replacement of the fan 3 or the bracket 4 is required, the user only needs to easily hold the handle 82 and take it out of the guide rail bracket 2 without worrying about inconvenience in operation or damage to the equipment. The design of the handle structure 8 provides convenience for the installation and maintenance of the fan 3 and the bracket 4, improving the convenience, safety and user experience of operation.

[0041] The guide rail bracket 2 is provided with a guiding and limiting strip 5. The guiding and limiting strip 5 is arranged along the length direction. The bracket 4 slides and abuts inside the guide rail bracket 2 along the guiding and limiting strip 5. The bracket 4 is fixedly connected to the guiding and limiting strip 5. At least part of the bracket 4 and the fan 3 extends out of the guide rail bracket 2.

[0042] The end of the guiding and limiting strip 5 is provided with a guiding inclined surface 51. In this embodiment, the bracket 4 is provided with a mating inclined surface. The guiding inclined surface 51 and the mating inclined surface are in abutting and fitting cooperation to achieve accurate alignment between the bracket 4 and the guiding and limiting strip 5. The design of the guiding inclined surface 51 enables the guiding and limiting strip 5 to more smoothly guide the bracket 4 to be installed on the guide rail bracket 2 and ensures that the bracket 4 maintains the correct direction and position during the installation process, improving the installation efficiency and the reliability of the connection.

[0043] During installation, each fan 3 is paired with its corresponding bracket 4, and the fan 3 is placed inside the bracket 4. The operator manipulates the handle structure 8 provided on the bracket 4 and pushes the multiple interconnected brackets 4 into the guide rail bracket 2 along the guiding and limiting strip 5. The guiding inclined surface 51 of the guiding and limiting strip 5 guides the bracket 4 to accurately enter the guide rail bracket 2. The bracket 4 slides inside the guide rail bracket 2 and the bracket 4 is fixedly connected to the guiding and limiting strip 5, thus realizing the installation and pulling of the fan assembly 1.

[0044] During this process, the guiding and limiting strip 5 can effectively limit the moving range of the bracket 4 inside the guide rail bracket 2, realizing the limiting and guiding of the bracket 4. Since the connection between the bracket 4 and the fan 3 is restricted inside the guide rail bracket 2, and at least part of the bracket 4 and the fan 3 extends out of the guide rail bracket 2, this design can reduce the space occupied by the fan assembly 1 in the thickness direction, enabling the fan 3 to be arranged closer to the air guiding structure 10 of the energy storage device. The air guiding structure 10 can then more effectively guide the air flow, thereby improving the heat dissipation effect of the energy storage device.

[0045] The bracket 4 includes a first plate 41 and a second plate 42 that wrap the fan 3 in the thickness direction, and a baffle 43 that wraps the fan 3 in the length direction. The first plate 41 and the second plate 42 are disposed on both sides of the baffle 43; the first plate 41 and the second plate 42 in the bracket 4 are disposed on the upper and lower sides of the fan 3 instead of the front and rear sides of the fan 3, so that the bracket 4 does not need to directly cover the front and rear surfaces of the fan 3 in the thickness direction, avoiding a full wrap of the fan 3 in the thickness direction;

[0046] The guide rail bracket 2 includes a third plate 21 and a fourth plate 22 that wrap the bracket 4 in the thickness direction, and a mounting plate 23 that wraps the bracket 4 in the length direction. The third plate 21 and the fourth plate 22 are disposed on both sides of the mounting plate 23. In this embodiment, a plurality of mounting holes 211 are provided on the third plate 21; the third plate 21 and the fourth plate 22 in the guide rail bracket 2 are disposed on the upper and lower sides of the bracket 4 instead of the front and rear sides of the bracket 4, so that the guide rail bracket 2 does not need to directly wrap the front and rear surfaces of the bracket 4, avoiding a full wrap of the fan 3 in the thickness direction;

[0047] The first plate 41 abuts against the third plate 21, and the second plate 42 abuts against the fourth plate 22. The width of the first plate 41 is greater than the width of the third plate 21, and the width of the fourth plate 22 is greater than the width of the second plate 42. The guiding and limiting strip 5 is disposed on the fourth plate 22, and the second plate 42 is fixedly connected to the guiding and limiting strip 5; the above design causes the bracket 4 and the guide rail bracket 2 to be misaligned in the thickness direction, achieving the purpose that the bracket 4 and the fan 3 at least partially extend out of the guide rail bracket 2, further reducing the thickness of the overall structure in the thickness direction, saving the installation space occupied by the fan assembly 1, and being able to reduce the gap between the fan assembly 1 and the air guiding structure 10 on the energy storage device, thereby improving the heat dissipation effect.

[0048] The first plates 41 of adjacent brackets 4 are connected by hinges. A guiding connection block 6 is provided on the side where the first plate 41 extends out of the third plate 21. In this embodiment, the guiding connection block 6 serves as a subsequent connection guiding structure for the energy storage device. By providing a connection structure on the first plate 41 of the bracket 4 instead of on the guide rail bracket 2, the occupied space of the fan assembly 1 can be reduced while enabling the subsequent connection guiding of the fan assembly 1 to the energy storage device, solving the problem of insufficient space;

[0049] Both ends of the guiding connection block 6 are provided with guiding arc surfaces 61; during the actual installation process, the design of the guiding arc surfaces 61 enables the guiding connection block 6 to pass more smoothly through the connection part of the energy storage device during installation, can guide the guiding connection block 6 to move along the expected path, ensure its correct alignment to the connection point of the device, thereby avoiding possible deviations or misalignments during installation, and the guiding arc surfaces 61 also help to reduce the collision and friction between the connection block and the energy storage device, reducing the risk of damage caused by the installation process.

[0050] On one side of the fourth plate 22 away from the mounting plate 23, there is a stepped portion 7. The guiding and limiting strip 5 is located on the side of the fourth plate 22 close to the stepped portion 7. In this embodiment, the stepped portion 7 is a structure formed by bending the end of the fourth plate 22 upward. There are several connecting holes 71 on the stepped portion 7; the stepped portion 7 can serve as a support point, providing additional support and installation space, ensuring that the device or structure remains stable and balanced after installation, being able to make the most of the available space within a limited space, increasing space utilization efficiency, and providing convenience for installing other components or accessories, such as accommodating the laying of the fan wire harness, while enhancing the strength and stability of the entire structure.

[0051] The implementation principle of the embodiment of this application is as follows: For the fan assembly 1 of this application, by designing the first plate 41 and the second plate 42 in the bracket 4 to be arranged on the upper and lower sides of the fan 3 instead of on the front and rear sides of the fan 3, and the third plate 21 and the fourth plate 22 in the guide rail bracket 2 to be arranged on the upper and lower sides of the bracket 4 instead of on the front and rear sides of the bracket 4, it avoids a full - range covering of the fan 3 and the bracket 4 in the thickness direction, reducing the space occupied by the fan assembly 1 in this direction;

[0052] And the setting of the guiding and limiting strip 5 can effectively limit the moving range of the bracket 4 within the guide rail bracket 2, realizing the limiting and guiding of the bracket 4. Moreover, at least part of the bracket 4 and the fan 3 extend out of the guide rail bracket 2. This design can reduce the space occupied by the fan assembly 1 in the thickness direction; and by setting the connecting structure on the first plate 41 of the bracket 4 instead of on the guide rail bracket 2, it can reduce the occupied space of the fan assembly 1 and at the same time realize the connection and guiding of the fan assembly 1 with the energy storage device in the future, improving the overall space utilization efficiency, enabling the fan 3 to be arranged closer to the air guiding structure 10 of the device. The air guiding structure 10 can then more effectively guide the air flow, thereby improving the heat dissipation effect of the device.

[0053] Embodiment Two

[0054] Please refer to Figures 4-5 As shown, this embodiment provides a device housing 9, and the device housing 9 includes but is not limited to being the housing of an energy storage device. The device housing 9 includes an air guiding structure 10 and the fan assembly 1 as described in Embodiment One; the device housing 9 is provided with a receiving groove 91. The fan assembly 1 slides and abuts within the receiving groove 91 and is fixed within the receiving groove 91. The air guiding structure 10 is arranged within the receiving groove 91, and the air guiding structure 10 is arranged along the height direction and abuts against the guide rail bracket 2 of the fan assembly 1;

[0055] During installation, the fan assembly 1 is installed in the receiving groove 91 of the device housing 9. At this time, the air guiding structure 10 of the device housing 9 will abut against the guide rail frame 2 of the fan assembly 1, so that the gap between the fan assembly 1 and the air guiding structure 10 can meet the actual use requirements; by using the design of the fan assembly 1 in the first embodiment, since the fan assembly 1 is restricted within the guide rail frame 2 and at least partially extends out of the guide rail frame 2, this design can reduce the space occupied by the fan assembly 1 in the thickness direction, shorten the distance from the fan assembly 1 to the air guiding structure 10 of the device housing 9. By combining the fan assembly 1 with the air guiding structure 10 of the device housing 9, the air guiding gap can be reduced, the air leakage problem can be improved, and it is ensured that more of the airflow blown out by the fan 3 passes through the air guiding structure 10, thereby improving the heat dissipation performance of the device.

[0056] The receiving groove 91 is provided with a communicating guiding groove 92. In this embodiment, the guiding groove 92 is arranged along the groove body direction of the receiving groove 91. The guiding connection block 6 on the first plate 41 of the bracket 4 slides and abuts within the guiding groove 92, and the guiding connection block 6 is fixed within the guiding groove 92; during the installation process, due to the design of the guiding groove 92, the guiding connection block 6 of the bracket 4 can be accurately aligned with the guiding groove 92, so as to ensure that the fan assembly 1 can be correctly positioned and fixed within the receiving groove 91 of the device housing 9, thereby improving the installation efficiency and product quality;

[0057] The handle structure 8 abuts against the outer wall of the device housing 9, the air guiding structure 10 abuts against the stepped portion 7, and the guide rail frame 2 abuts against the receiving groove 91; the abutment between the guide rail frame 2 and the receiving groove 91 can ensure the stable installation of the fan assembly 1 on the device housing 9. The abutment between the air guiding structure 10 and the stepped portion 7 enables the air guiding structure 10 to more stably guide the airflow generated by the fan assembly 1 to the device housing 9. The abutment between the handle structure 8 and the outer wall of the device housing 9 helps to provide additional support and stability;

[0058] The handle structure 8 and the device housing 9, the air guiding structure 10 and the stepped portion 7, and the guide rail frame 2 and the receiving groove 91 are all fixed by screws; by fixing the handle structure 8, the air guiding structure 10, the guide rail frame 2 and the device housing 9 with screws, the tight connection and stability between them are ensured. This fixing method makes the device not easily affected by external vibration or impact during operation; and in the design of this application, the guide rail frame 2 and the bracket 4 are respectively fixed to the device housing 9, which facilitates the subsequent maintenance work of the fan 3. When it is necessary to maintain or replace the fan 3 within the bracket 4, only the connection between the bracket 4 and the device housing 9 needs to be released to replace the fan, without having to disassemble the device housing together with all the internal and external parts, which can save time and manpower and reduce the interference to the device during the maintenance process, making the maintenance process more efficient and convenient.

[0059] The implementation principle of the embodiments of this application is as follows: During installation, the fan assembly 1 is installed in the accommodation groove 91 of the device housing 9. Specifically, in the fan assembly 1, the mounting holes 211 on the guide rail frame 2 are aligned with the mounting holes in the accommodation groove 91 of the device housing 9, and are fastened with screws. Then, the connection holes 71 are aligned with the corresponding mounting holes of the device housing 9 for fastening, thus completing the installation of the guide rail frame 2 of the fan assembly 1;

[0060] During installation, the fan 3 is installed on the bracket 4. Specifically, the fan 3 is aligned with the bracket 4, and the fan 3 is successively installed on the bracket 4 using countersunk flat-tail self-tapping screws; Then, the operator manipulates the handle structure 8 provided on the bracket 4 to push the entire fan assembly 1 into the accommodation groove 91. At this time, the guiding connection block 6 will abut against the guiding groove 92, and the air guiding structure 10 of the device housing 9 will abut against the step portion 7 of the guide rail frame 2 of the fan assembly 1. The entire fan assembly 1 abuts against the accommodation groove 91, and the handle structure 8 abuts against the outer wall of the device housing 9; Then, the handle structure 8, the air guiding structure 10, the guide rail frame 2 and the device housing 9 are fixed with screws, ensuring the tight connection and stability between them;

[0061] With the design of the fan assembly 1 in the first embodiment, the device housing 9 of this application can reduce the space occupied by the fan assembly 1 in the thickness direction, shorten the distance from the fan assembly 1 to the air guiding structure 10 of the device housing 9. By combining the fan assembly 1 with the air guiding structure 10 of the device housing 9, the air guiding gap can be reduced, the air leakage problem can be improved, and it is ensured that more air flow blown out by the fan 3 passes through the air guiding structure 10, thereby improving the heat dissipation performance of the device.
