Description

Technical Field

[0001] This application relates to the field of heat dissipation equipment technology, and more specifically, to a series fan housing and a series fan. Background Technology

[0002] With the rapid development of data centers and 5G base stations, the demand for high-density heat dissipation systems is increasing. To improve the air pressure and heat dissipation efficiency of fans, the application of multi-fan series connection has been promoted.

[0003] The tandem fan housing is the main load-bearing component for the internal fan. The tandem fan housing is usually formed by assembling the housing body in series. Therefore, the reliability of the connection between the housing bodies will directly affect the performance of the tandem fan.

[0004] Currently, the connection of series fan frames on the market mainly adopts the method of snap-fit ​​plate and convex buckle, which has poor connection reliability. After long-term use, the series fan frame is prone to loosening, and there is even a risk of disintegration. Utility Model Content

[0005] This application provides a series fan housing, which solves the problem of poor connection stability of series fan housings, improves installation accuracy, and enhances the firmness of the connection.

[0006] In a first aspect, this application provides a series fan frame, comprising at least two frame bodies connected in series, each frame body having a connecting end face, and further comprising:

[0007] A limiting component is disposed on the connecting end face. The limiting component includes an axial limiting component and a circumferential limiting component. The axial limiting component is used to guide the two frame bodies to be connected in series to move towards each other along the axial direction so that the connecting end faces to be connected fit together. The circumferential limiting component is used to guide the two fitted frame bodies to move circumferentially between an unlock position and a locking position.

[0008] A locking component is disposed on the connection end face. The locking component is used to lock the two frame bodies to the locked position and to unlock the two frame bodies to the unlocked position.

[0009] In this embodiment, an axial limiting component, a circumferential limiting component, and a locking component are provided on the connecting end faces of two series-connected frame bodies. The axial limiting component guides the two series-connected frame bodies to move towards each other along the axial direction, enabling the connecting end faces to fit quickly and accurately, improving assembly efficiency. The circumferential limiting component guides the two frame bodies to move circumferentially between the unlocked and locked positions, ensuring alignment accuracy during the connection process and preventing misalignment. The locking component effectively locks the two frame bodies in the locked position, improving connection stability and reliability and preventing loosening during operation. Furthermore, this application has a simple structure and compact layout, does not occupy the external space of the fan frame, and can achieve a secure locking between series-connected fan frames.

[0010] In some embodiments, the locking component includes a cantilever and a first snap-fit ​​member. The cantilever is fixedly connected to the connection end face of one of the series-connected frame bodies. The cantilever is provided with a second snap-fit ​​member. The outer wall surface of the other series-connected frame body is provided with a mounting groove. The first snap-fit ​​member is fixedly disposed in the mounting groove and is used to snap-fit ​​and adapt to the second snap-fit ​​member.

[0011] After being guided into the locking position by the axial and circumferential limiting components, the two frame bodies are engaged with the first locking component of the cantilever assembly via the second locking component, achieving a secure lock and improving the stability of the connection. The cantilever assembly can be completely accommodated within the mounting slot, without occupying external space of the frame body, resulting in a more aesthetically pleasing appearance.

[0012] In some embodiments, the cantilever member and the first snap-fit ​​member constitute a first snap-fit ​​assembly, and there are multiple first snap-fit ​​assemblies, which are evenly distributed circumferentially on the connection end faces of the two series-connected frame bodies.

[0013] By uniformly arranging multiple first locking components circumferentially on the connecting end faces of two series-connected frame bodies, a circumferentially uniform locking structure can be formed, improving the locking force and making the connection between the two frame bodies more secure, thus avoiding loosening or displacement caused by uneven force.

[0014] In some embodiments, the side peripheral wall of the first snap-fit ​​member is provided with a guide surface, which is used to guide the second snap-fit ​​member to snap into the first snap-fit ​​member.

[0015] By providing a guide surface on the side wall of the first snap-fit ​​component, the second snap-fit ​​component can be effectively guided to enter along the guide surface and snap into the first snap-fit ​​component, thereby improving the smoothness of the engagement.

[0016] In some embodiments, the mounting groove includes a vertical sub-mounting groove and a circumferential sub-mounting groove. The vertical sub-mounting grooves are vertically distributed, and the circumferential sub-mounting grooves are connected to the vertical sub-mounting grooves. The movable end of the cantilever is fixedly connected to a snap-fit ​​portion, and the second snap-fit ​​member is disposed on the snap-fit ​​portion. The vertical sub-mounting groove is used to guide the cantilever and the snap-fit ​​portion to enter axially. The vertical sub-mounting groove and the cantilever form the axial limiting component, and the circumferential sub-mounting groove and the snap-fit ​​portion form the circumferential limiting component.

[0017] The use of vertical and circumferential mounting slots allows for axial and circumferential movement and adjustment of the cantilever components, facilitating precise installation and disassembly.

[0018] In some embodiments, the circumferential limiting component further includes a guide groove and a guide post, the guide groove and the guide post being respectively disposed on the connecting end faces of the two frame bodies connected in series, and the guide post being slidably adapted to the guide groove.

[0019] By employing a combination of guide grooves and guide posts in the circumferential limiting component, the radial displacement of the frame can be effectively limited, thereby improving the rigidity and stability of the overall structure.

[0020] In some embodiments, there are multiple guide posts distributed on the same connecting end face of the frame body, and the guide grooves are correspondingly set and slidably adapted to the guide posts.

[0021] By evenly distributing multiple guide posts on the connecting end face, it is possible to ensure precise positioning of the frame body and the docking components, avoiding offset or misalignment during assembly.

[0022] In some embodiments, the length of the circumferential sub-mounting slot is greater than the length of the vertical sub-mounting slot in the circumferential direction.

[0023] The length of the circumferential sub-mounting groove is greater than the length of the vertical sub-mounting groove to form a circumferential sliding adjustment space for the cantilever component. The cantilever component, which enters the circumferential sub-mounting groove from the vertical sub-mounting groove, moves along the circumferential sub-mounting groove to a preset displacement and gradually locks in until the first snap-fit ​​component is completely snapped into the second snap-fit ​​component, thus achieving flexible assembly. The circumferential adjustment space can compensate for errors and avoid assembly failures caused by misalignment, thereby reducing processing accuracy and assembly accuracy.

[0024] In some embodiments, the locking assembly further includes a second locking member, which includes a protrusion and a limiting post. The connecting end face of one of the frame bodies connected in series is provided with a receiving groove, and the protrusion is disposed in the receiving groove. The connecting end face of the other frame body extends to form the limiting post, and the receiving groove is used to accommodate the limiting post. The cantilever member, the receiving groove, and the protrusion form a limiting space for circumferentially limiting the limiting post.

[0025] By adding a second locking element to the first locking element, the reliability of the locking can be further improved, preventing the series fan frame from being unlocked under external force, thus improving the reliability of the locking.

[0026] Secondly, embodiments of this application provide a series fan, including a series fan housing as described in any of the preceding claims.

[0027] In this embodiment, a multi-directional limiting and bi-directional rotary self-locking structure is adopted. During installation, the two frame bodies are first guided to move axially by the axial limiting component, so that the connecting end faces are fitted together to achieve axial clamping. The two frame bodies are then rotated counterclockwise and clockwise in a coordinated manner, and the locking component is adjusted to the locked position by the circumferential limiting component to achieve circumferential locking. This application has a compact layout, is convenient and quick to install, and provides a firm and reliable lock, thereby improving the assembly accuracy and assembly tightness of the tandem fan frame.

Obviously, the described embodiments are only some embodiments of this application, 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.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0043] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.

[0044] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone.

[0045] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0046] In this application, "multiple" means two or more (including two).

[0047] Please refer to Figure 1 and Figure 2 This application provides a series fan frame, mainly comprising at least two frame bodies 1. The frame bodies 1 may be, but are not limited to, square or annular frame structures. Each frame body 1 has at least one connecting end face 11 for connecting with other frames connected in series, forming a series fan frame. Fan blades and a drive motor are installed inside the frame body 1. The frame body 1 provides installation space for the fan blades and drive motor, maintaining the stability of the airflow channel. By connecting the frame bodies 1 in series, a series fan frame is formed, thereby achieving the superposition of wind pressure or airflow. The number of frame bodies 1 can be two or more, and the frame bodies 1 are connected in series through the connecting end faces 11 to form a multi-stage fan structure.

[0048] The limiting component 2 includes an axial limiting component 21 and a circumferential limiting component 22, both of which are disposed on the connecting end face 11. The axial limiting component 21 is used to guide the locking component 3 to move axially. The locking component 3 guides the two frame bodies 1 to move closer together axially, ensuring that the connecting end face 11 is completely fitted, preventing axial and radial misalignment, and ensuring the accuracy of subsequent circumferential position adjustment.

[0049] The circumferential limiting component 22 causes the frame body 1 to rotate relative to each other in the circumferential direction by a certain angle. The circumferential limiting component 22 and the axial limiting component 21 work together to limit the circumferential rotation angle of the frame body 1, ensuring that the locking component 3 can be accurately aligned and locked, thereby allowing the locking component 3 to move between the maximum unlock position and the locked position.

[0050] In this embodiment, when in the unlocked position, the connected frame bodies 1 are separated; when in the locked position, the relative positions between the connected frame bodies 1 are fixed.

[0051] The locking component 3 moves synchronously or in conjunction with the axial limiting component 21 and the circumferential limiting component 22. The locking component 3 is disposed on the connecting end face 11 of the series-connected frame body 1. When the frame body 1 rotates to the locked position, the locking component 3 locks both components together, achieving axial, circumferential, and radial limiting to prevent displacement in all three directions. When the frame body 1 rotates to the unlocked position, the locking component 3 disengages the components, allowing the frame body 1 to separate axially or rotate circumferentially for position adjustment and disassembly.

[0052] When locked, the two frame bodies 1 are brought closer together axially by the axial limiting component 21, guiding the connecting end faces 11 to fit together. Thereafter, by bidirectional rotation (for example, the first frame rotates counterclockwise and the second frame rotates clockwise), the locking component 3 moves from the unlocked position to the locked position, thereby locking the series-connected frame bodies 1.

[0053] When unlocking, rotate bidirectionally in the opposite direction to the locking direction (for example, the first frame rotates clockwise and the second frame rotates counterclockwise, so that when the locking component 3 is rotated to the unlock position, the locking component 3 is released from constraint, and the frame body 1 can be separated).

[0054] In this embodiment, the locking component 3 achieves locking and unlocking between the two frame bodies 1 through its mechanical action, specifically in two states: locked state and unlocked state. When the locking component 3 is triggered (e.g., tightened, pressed, or slid), it applies a constraint force to the two frame bodies 1, fixing their relative positions and reaching the locked position. At this time, there is no relative displacement between the frame bodies 1, ensuring connection stability. The series fan frame is in the locked state (see reference). Figure 1 Release the constraint of locking component 3 (e.g., reverse operation, such as unscrewing, pressing to release, or sliding in the opposite direction), allowing the two frame bodies 1 to separate freely or move relative to each other. At this time, the series fan frame is in the unlocked state (see reference). Figure 2 ).

[0055] The axial limiting component 21 and the circumferential limiting component 22 in this application also serve as radial limiting components, enabling multi-directional limiting and bi-directional rotational self-locking. The locking is secure, highly reliable, and prevents loosening due to external vibration. Furthermore, this application allows for tool-free assembly and disassembly, making it easy to operate.

[0056] Continue to refer to Figure 3In one specific embodiment, the locking component 3 includes a cantilever 31 and a first latching member 32. One end of the cantilever 31 is fixed to the frame body 1 and is fixedly connected to the connecting end face 11 of the first frame body 1, typically by welding, fastening with locking components, or integral molding. The other end of the cantilever 31 is a free end, and a second latching member 33a is provided at the free end of the cantilever 31. The free end of the cantilever 31 can elastically deform under force, achieving a fastening with the first latching member 32 and ensuring a stable connection between the two frame bodies 1.

[0057] refer to Figure 3 and combined Figure 4 For example, the first latching member 32 can be a buckle, and the second latching member 33a can be a latching hole. The latching hole can be circular, square, trapezoidal, or an irregularly shaped through hole, and the shape of the first latching member 32 matches that of the second latching member 33a. When assembling the tandem fan frame, the frame body 1 is rotated in the locking direction to engage the first latching member 32 with the second latching member 33a, thus locking the frame. When disassembling the tandem fan frame, the frame body 1 is rotated in the unlocking direction to disengage the first latching member 32 from the second latching member 33a, thus unlocking the fan.

[0058] In addition, the first snap-fit ​​component 32 can also be a snap hole, and the second snap-fit ​​component 33a can also be a snap buckle, or both the first snap-fit ​​component 32 and the second snap-fit ​​component 33a can be snap buckles to form a snap tooth structure, which can achieve interlocking through snap-fit ​​and mutual mating. Regarding the specific structure of the first snap-fit ​​component 32 and the second snap-fit ​​component 33a, in addition to the elastic snap hook structure, it can be a variety of other structures, such as magnetic attraction, snap button or pin, as long as the locking connection is achieved. This article does not limit this.

[0059] The outer wall of the frame body 1 is provided with a mounting groove 11a. The first snap-fit ​​member 32 is fixed in the mounting groove 11a of the frame body 1 and is connected to the mounting groove 11a by embedding, screw fastening, or integral molding. The protrusion 341 and the second snap-fit ​​member 33a form a mechanical interlock, and the connection between the two frame bodies 1 is achieved by snapping the second snap-fit ​​member 33a into the first snap-fit ​​member 32. When locked, the free end of the cantilever member 31 undergoes elastic deformation, causing the second snap-fit ​​member 33a to snap into the first snap-fit ​​member 32 to complete self-locking.

[0060] The cantilever component 31 and the first snap-fit ​​component 32 form the first snap-fit ​​assembly. There can be one or more first snap-fit ​​assemblies. Optionally, there can be multiple first snap-fit ​​assemblies, which are evenly distributed circumferentially on the connection end faces 11 of the two connected frame bodies 1 in series. This can form a circumferentially uniform snap-fit ​​structure, ensuring the uniformity of the locking force between the frame bodies 1, thereby improving the locking firmness.

[0061] In order to achieve smooth locking and unlocking of the first card assembly, a guide surface 321 can be provided on the side wall of the first card connector 32. The guide surface 321 can guide the relative sliding between the second card connector 33a and the first card connector 32 to avoid interference and jamming.

[0062] like Figure 5 As shown. In one specific embodiment, the mounting groove 11a includes a vertical sub-mounting groove 111a and a circumferential sub-mounting groove 112a. The vertical sub-mounting groove 111a is a groove that extends vertically (i.e. axially) and has a cross-sectional shape that matches the maximum size of the cantilever member 31 to ensure guided movement along the vertical sub-mounting groove 111a.

[0063] The vertical sub-mounting groove 111a guides the cantilever component 31 and the snap-fit ​​part 33 to be inserted axially and restricts the axial displacement of the cantilever component 31, ensuring linear alignment during assembly. The vertical sub-mounting groove 111a mates with the side wall of the cantilever component 31 to form the axial limiting assembly 21.

[0064] The circumferential sub-mounting groove 112a is a groove that surrounds the circumference (i.e., the direction of rotation). It can be arc-shaped, and a transition area is formed at the intersection of the circumferential sub-mounting groove 112a and the vertical sub-mounting groove 111a. After the engaging part 33 enters the circumferential sub-mounting groove 112a, it rotates a certain angle along the circumferential sub-mounting groove 112a to the locking position. At this time, the end face of the engaging part 33 abuts against the groove wall of the circumferential sub-mounting groove 112a, and the groove wall limits the rotation angle of the engaging part 33. The circumferential sub-mounting groove 112a and the engaging part 33 form a circumferential limiting component 22.

[0065] Therefore, the axial direction is constrained by the vertical sub-mounting groove 111a and the cantilever member 31, and the circumferential direction is constrained by the snap-fit ​​part 33 and the circumferential sub-mounting groove 112a. Thus, the vertical sub-mounting groove 111a and the circumferential sub-mounting groove 112a form a double limiting structure, which can satisfy the positioning in the axial, circumferential and radial directions.

[0066] In addition, the circumferential limiting component 22 also includes a guide groove 221 and a guide post 222. The guide groove 221 and the guide post 222 are respectively disposed on the connection end face 11 of the two frame bodies 1 connected in series. The guide post 222 and the guide groove 221 are slidably adapted.

[0067] The guide groove 221 is formed on the connecting end face 11 of the frame body 1. It is a semi-enclosed channel. The guide groove 221 is a groove structure formed circumferentially along the connecting end face 11. The cross-sectional shape can be rectangular, trapezoidal, or dovetail-shaped. Optionally, the open end of the guide groove 221 is chamfered to facilitate the initial alignment of the guide post 222.

[0068] The guide post 222 is fixed to the corresponding end face of the adjacent frame body 1 and has a protruding structure 341, such as a strip or block structure. The outer contour shape and size of the guide post 222 match the guide groove 221, and its size is slightly smaller than the guide groove 221 to achieve sliding fit.

[0069] In this embodiment, the guide groove 221 and guide post 222 work together to achieve circumferential limiting, thereby restricting the relative rotation angle of the frame bodies 1 around the axis. During unlocking or locking, the guide post 222 slides along the guide groove 221, guiding the frame bodies 1 to move along the predetermined unlocking path or the predetermined locking path to prevent deflection and ensure that when the movement reaches the unlocking range, the locking component 3 unlocks, and when the movement reaches the locking position, the locking component 3 locks.

[0070] The guide post 222 and the guide groove 221 cooperate to form the second circumferential limiting component 22. Multiple guide posts 222 and guide grooves 221 can be set, and can be circumferentially symmetrically distributed to form multiple guiding structures, which can improve the motion accuracy.

[0071] Optionally, the width of the circumferential sub-mounting groove 112a is greater than the width of the vertical sub-mounting groove 111a in the circumferential direction to form a circumferential guide space.

[0072] like Figure 4 As shown. Exemplarily, the cantilever component 31 includes a straight arm and a guide block. The guide block is located at the free end of the straight arm and extends to one side. The straight arm is vertically distributed, and the guide block is integrally formed with the straight arm. The straight arm mainly cooperates with the vertical sub-mounting groove 111a and slides vertically along the vertical sub-mounting groove 111a. The guide block cooperates with the circumferential sub-mounting groove 112a and slides along the circumferential sub-mounting groove 112a to adjust the locking state.

[0073] To enhance locking stability, another locking component 3 can be further provided. Specifically, the locking component 3 also includes a second locking member 34, which includes a protrusion 341 and a limiting post 342. The connecting end face 11 of one frame body 1 connected in series is provided with a receiving groove 11b, and the protrusion 341 is disposed in the receiving groove 11b. The connecting end face 11 of the other frame body 1 extends to form a limiting post 342. The receiving groove 11b can accommodate the limiting post 342. The cantilever member 31, the receiving groove 11b and the protrusion 341 form a limiting space to circumferentially limit the limiting post 342.

[0074] When locking is required, the limiting post 342 rotates along the receiving groove 11b until it passes the protrusion 341, at which point the limiting post 342 moves into the limiting space and is in the locked position. The limiting post 342 is blocked and limited by the protrusion 341 and the straight arm, forming a double locking structure with the first locking member 32 and the second locking member 33a to prevent reverse locking. When unlocking is required, the limiting post 342 rotates in the opposite direction along the receiving groove 11b until it passes the protrusion 341, at which point the limiting post 342 disengages from the limiting space and is in the unlocked position. The limiting post 342 is blocked and limited by the protrusion 341 and the groove arm of the mounting groove.

[0075] In summary, this application provides a series fan frame 100, which adopts a bidirectional rotational self-locking structure, using counter-rotation and forward rotation to achieve axial clamping and circumferential locking. Simultaneously, a multi-directional limiting structure is employed to ensure axial, circumferential, and radial constraints during rotation, thereby improving the robustness and stability of the frame body 1 connection.

[0076] In addition, this application also provides a series fan, including a series fan frame 100. This series fan, having the aforementioned series fan frame 100, enables precise and secure assembly and disassembly, thereby greatly improving work efficiency.

Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of this application.
