Description

Technical Field

[0001] This invention relates to the field of switch technology, specifically to a quick-release air-cooled chassis with front-to-back airflow. Background Technology

[0002] As electronic devices such as communication equipment, industrial control computers, servers, and energy storage converters develop towards higher integration and higher power density, the heat generated during equipment operation increases significantly. Heat dissipation capacity directly determines the stability and lifespan of the equipment. Forced air cooling structures with front-to-back airflow have become the mainstream heat dissipation method for rack-mounted electronic equipment chassis due to their simple airflow and stable heat dissipation efficiency.

[0003] In practical engineering applications, fans, as consumable components, require regular maintenance, replacement, and overhaul. However, existing air-cooled enclosures generally suffer from the following common technical defects: fans are mostly installed using bolt fastening, requiring screwdrivers, hex wrenches, and other tools for disassembly and assembly, resulting in cumbersome and time-consuming maintenance processes and low on-site operation and maintenance efficiency; fan installation lacks reliable guiding and positioning structures, making it prone to tilting and jamming during installation, resulting in poor assembly accuracy, loosening and abnormal noises during long-term operation, and also compromising the air duct's sealing; the fan's power supply connectors and speed control feedback connectors are mostly hidden inside the enclosure or behind the fan, making it impossible to visually observe whether the connections are in place after installation, easily leading to faults such as loose connections, missing connections, and poor contact, causing fan shutdown, equipment overheating, and downtime; the air duct structure is open with large gaps, resulting in air leakage, cross-flow, and turbulence, low effective airflow utilization, poor heat dissipation, and high operating noise.

[0004] In the prior art, the closest to this invention is a chassis with a quick-change air-cooling module (CN202522694652.6), which discloses a side-pluggable fan module structure, enabling tool-free quick replacement and improving maintenance efficiency to some extent. However, this chassis still has problems such as insufficient positioning accuracy, invisible electrical connectors, and poor air duct sealing, failing to fundamentally solve the systemic defects of existing air-cooling chassis. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a quick-release air-cooled chassis with front airflow and rear airflow.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quick-release air-cooled chassis with front airflow and rear airflow, comprising a chassis body and a fan unit, wherein the chassis body is provided with a front shielding window at the front and a removable rear shielding window at the rear.

[0007] The wind turbine unit has an independent modular structure and can be plugged into the chassis body from top to bottom.

[0008] The fan unit includes a top plate, a front air inlet mounting plate, a rear air outlet mounting plate, a bottom plate, and left and right side plates; the fan is fixedly installed on the front air inlet mounting plate; the rear air outlet mounting plate has a fan inlet and a plug / socket viewing port; the front air inlet mounting plate and the rear air outlet mounting plate cooperate with each other to close the gaps around the fan unit, forming a one-way air duct that only allows airflow through the fan inlet;

[0009] The left and right side plates are provided with guide rails on their outer sides, and the corresponding positions of the chassis body are provided with guide rail grooves that are adapted to the guide rails; the bottom plate is provided with guide pins, power plugs and speed control feedback plugs, and the corresponding positions of the chassis body are provided with guide pin seats, power sockets and speed control feedback sockets; when the fan unit is inserted into the chassis body from top to bottom, the guide pins and guide pin seats cooperate to achieve positioning, and the power plugs and speed control feedback plugs are synchronously connected to the corresponding sockets during the insertion and removal action;

[0010] The top plate is equipped with a folding handle and is fixed to the chassis body by a detachable fastener. After removing the detachable rear shielding window, the contact status of the power supply plug, speed control feedback plug and corresponding socket can be observed through the plug and socket viewing port.

[0011] In some embodiments, the top plate, front air inlet mounting plate, rear air outlet mounting plate, bottom plate, and left and right side plates of the fan unit enclose an independent modular cavity; the front air inlet mounting plate and the rear air outlet mounting plate respectively enclose the front and rear of the fan unit, the left and right side plates enclose the left and right sides of the fan unit, the bottom plate encloses the bottom of the fan unit, the top plate encloses the top of the fan unit, and only the fan outlet on the rear air outlet mounting plate allows airflow to pass through.

[0012] In some embodiments, guide rails are fixedly installed on the outer sides of the left and right side plates, and guide rail grooves adapted to the guide rails are opened at corresponding positions on the chassis body. The guide rails and guide rail grooves slide together to provide guidance for the insertion and removal of the fan unit.

[0013] In some embodiments, there are two guide pins, which are set on the bottom plate. The corresponding position of the chassis body is provided with a guide pin seat plate. When the fan unit is inserted into the chassis body from top to bottom, the two guide pins and the guide pin seat plate cooperate precisely to achieve bidirectional positioning.

[0014] In some embodiments, the power supply socket and the speed control feedback socket are fixed to a socket mounting plate, which is mounted on the chassis body.

[0015] In some embodiments, the folding handles are a pair, mounted on the top plate, and can be folded and stored on the surface of the top plate.

[0016] In some embodiments, the top plate is detachably fixed to the chassis body by screws.

[0017] In some embodiments, airflow enters the chassis body through the front shielding window, flows through the functional areas inside the chassis body and reaches the fan unit, and finally exits through the removable rear shielding window, forming a complete front-to-back airflow cooling duct.

[0018] In some embodiments, the plug and socket viewing port is located on the rear air outlet mounting plate and corresponds to the positions of the power socket and the speed control feedback socket.

[0019] In some embodiments, the guide rail and the guide rail groove cooperate to achieve coarse guidance for the insertion and removal of the fan unit, and the guide pin and the guide pin seat plate cooperate to achieve fine positioning when the fan unit is inserted, together forming a dual guide positioning structure.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] Because this invention adopts a modular, top-to-bottom vertical plug-in assembly method for wind turbine units, it can achieve quick assembly and disassembly without tools, making operation simple and maintenance efficiency greatly improved.

[0022] Thanks to the dual guiding and positioning structure of coarse guide rail and fine guide pin, the fan assembly is precise, without skewing or jamming, and operates stably without abnormal noise.

[0023] Because of the structure that allows the bottom power supply plug and speed control feedback plug to be plugged in and out simultaneously, mechanical positioning and electrical connection are completed in one step, ensuring reliable wiring, stable contact, and a significantly reduced failure rate.

[0024] With the addition of a removable shielded window at the rear and a visible port for the plug and socket, the wiring status can be directly inspected, and loose connections and missing parts can be eliminated in advance, greatly improving the safety and reliability of the equipment operation.

[0025] Because it adopts a unidirectional air duct structure with closed front and rear panels and ventilation only at the fan inlet, the airflow is turbulent, leak-proof, and does not cross-flow, resulting in high air volume utilization, improved heat dissipation efficiency, and reduced operating noise.

[0026] In summary, this invention brings functional improvements through structural innovation, and has outstanding advantages such as quick assembly and disassembly, accurate positioning, reliable connection, intuitive inspection, efficient heat dissipation, and stable operation.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1

[0037] like Figures 1 to 5 As shown, this embodiment provides a quick-release air-cooled chassis with front airflow and rear airflow, including a chassis body 2 and a fan unit 3 as an independent modular structure.

[0038] The chassis body 2 is a rectangular frame structure with a front shielding window 1 fixedly installed at the front and a removable rear shielding window 4 installed at the rear. The front shielding window 1 has a grid or mesh structure, allowing cooling airflow into the chassis. The removable rear shielding window 4 is detachably connected to the rear frame of the chassis body 2 by screws or clips, and can be removed to expose the rear internal space of the chassis.

[0039] The fan unit 3 is an independent modular structure, with an overall rectangular box shape, which can be vertically plugged in and unplugged into the pre-set mounting cavity at the rear of the chassis body 2. The fan unit 3 includes a top plate 32, a front air inlet mounting plate 31, a rear air outlet mounting plate 34, a bottom plate 39, and left and right side plates 311. The above plates enclose a modular cavity with a closed bottom and top and a hollow interior. The fan 35 is fixedly mounted on the front air inlet mounting plate 31 with screws. The air inlet of the fan 35 faces the outside of the front air inlet mounting plate 31, and the air outlet faces the rear air outlet mounting plate 34. The rear air outlet mounting plate 34 has a fan outlet corresponding to the air outlet of the fan 35, and a plug and socket viewing port located below the fan outlet. The four edges of the front air inlet mounting plate 31 and the rear air outlet mounting plate 34 are tightly fitted with the left and right side plates 311, the top plate 32, and the bottom plate 39, respectively, sealing the gaps around the fan unit 3 and forming a one-way air duct that only allows airflow to pass through the fan inlet.

[0040] Long strip guide rails 310 are fixedly installed on the outer sides of the left and right side plates 311 by screws. Guide rail grooves that match the cross-sectional shape of the guide rails 310 are opened on the left and right inner side walls of the corresponding mounting cavity of the chassis body 2. The guide rails 310 slide with the guide rail grooves to provide coarse guidance for the insertion and removal of the fan unit 3 from top to bottom, and to prevent the fan unit 3 from deviating to the left or right during the insertion process.

[0041] Two cylindrical guide pins 36, a power supply plug 38, and a speed feedback plug 37 are fixedly mounted on the lower surface of the bottom plate 39. The two guide pins 36 are symmetrically arranged along the longitudinal center line of the bottom plate 39, located on both sides of the power supply plug 38 and the speed feedback plug 37. A guide pin seat plate 8 is provided at the bottom of the mounting cavity of the chassis body 2, and the guide pin seat plate 8 has guide holes corresponding to the diameter and position of the guide pins 36. The power supply socket 6 and the speed feedback socket 5 are fixedly mounted on the socket fixing plate 7, which is fixed to the bottom of the mounting cavity of the chassis body 2 by screws, and the positions of the power supply socket 6 and the speed feedback socket 5 correspond to the power supply plug 38 and the speed feedback plug 37, respectively.

[0042] When the fan unit 3 is inserted into the casing body 2 from top to bottom, the guide rail 310 first enters the guide rail groove for coarse guidance. As the fan unit 3 continues to descend, the two guide pins 36 are respectively inserted into the corresponding guide holes of the guide pin seat plate 8 for bidirectional fine positioning. At the same time, the power supply plug 38 and the speed control feedback plug 37 are simultaneously inserted into the power supply socket 6 and the speed control feedback socket 5, respectively, completing the synchronous docking of mechanical positioning and electrical connection. The fit clearance between the guide pin 36 and the guide pin seat plate 8 is smaller than the fit clearance between the guide rail 310 and the guide rail groove, ensuring precise alignment of the electrical connection.

[0043] A pair of folding handles 33 are installed on the upper surface of the top plate 32. The folding handles 33 are hinged to the top plate 32 via a pivot. They can be flipped around the pivot to a vertical position for gripping and lifting, or flipped to a horizontal position to fit snugly into the surface of the top plate 32. The top plate 32 has through holes at its four corners, which can be detachably fixed to the corresponding screw holes on the top of the chassis body 2 by screws, so as to realize quick locking and unlocking of the fan unit 3.

[0044] The chassis body 2 has a functional module installation area inside. Airflow enters the chassis body 2 through the front shielding window 1, flows through the internal functional module area and carries away heat, and then reaches the front air intake mounting plate 31 of the fan unit 3. Under the suction of the fan 35, it passes through the fan 35 and is discharged through the fan port on the rear air outlet mounting plate 34. Finally, it is discharged outside the chassis through the detachable rear shielding window 4, forming a complete front air and rear air outlet heat dissipation air duct.

[0045] When it is necessary to check the wiring status, remove the removable rear shielding window 4. The operator can directly observe the plug-in status of the power supply plug 38 and power supply socket 6, and the speed control feedback plug 37 and speed control feedback socket 5 through the plug and socket viewing port on the rear air outlet mounting plate 34, and determine whether there are any loose connections, misalignments or omissions.

[0046] Example 2

[0047] The difference between this embodiment and Embodiment 1 lies in the specific implementation of the guide positioning structure. In this embodiment, the outer sides of the left and right side plates 311 are integrally formed with protruding guide ribs, and the corresponding positions of the chassis body 2 are provided with guide grooves adapted to the guide ribs. The guide ribs and guide grooves slide together to achieve coarse guidance for the insertion and removal of the fan unit 3. The lower surface of the bottom plate 39 is provided with a positioning boss, and the corresponding positions of the chassis body 2 are provided with positioning holes. The positioning boss and positioning holes are inserted together to achieve fine positioning. The remaining structure and working principle are the same as in Embodiment 1. This embodiment shows that the guide positioning structure can adopt various conventional mechanical guide positioning forms such as guide rails and grooves, guide ribs and grooves, and positioning bosses and positioning holes, all of which can achieve precise assembly of the fan unit 3.

[0048] Example 3

[0049] The difference between this embodiment and Embodiment 1 lies in the electrical connection method. In this embodiment, the lower surface of the bottom plate 39 of the fan unit 3 is provided with an elastic conductive spring, and the corresponding position of the chassis body 2 is provided with a conductive contact plate. After the fan unit 3 is inserted into place, the elastic conductive spring and the conductive contact plate are elastically pressed together to realize the power supply and speed control signal transmission of the fan. Alternatively, quick-connect connectors are provided on the outer sides of the left and right side plates 311 of the fan unit 3, and the corresponding positions of the chassis body 2 are provided with docking sockets. When the fan unit 3 is inserted, the quick-connect connectors and docking sockets are inserted synchronously. The remaining structure and working principle are the same as in Embodiment 1. This embodiment shows that the electrical connection can adopt various methods such as plug and socket, spring contact, pin connection, quick-connect connector, etc., all of which can realize the electrical conduction between the fan unit 3 and the chassis body 2.

[0050] Example 4

[0051] The difference between this embodiment and Embodiment 1 lies in the fixing method of the fan unit 3. In this embodiment, the top plate 32 and the chassis body 2 are fixed together by a rotating locking structure for detachable fixing. The top plate 32 has rotatable locking handles on both sides, and the chassis body 2 has corresponding locking slots. After the fan unit 3 is inserted, the rotating locking handles engage with the locking slots, achieving tool-free quick locking; to unlock, the locking handles are rotated in the opposite direction to release the fixation. Alternatively, the top plate 32 and the chassis body 2 can be fixed together by an elastic locking plate structure. The elastic locking plate is located at the edge of the top plate 32, and after the fan unit 3 is inserted, the elastic locking plate automatically engages with the slot in the chassis body 2. The remaining structure and working principle are the same as in Embodiment 1. This embodiment shows that the fan unit 3 can be fixed using various quick-locking structures such as screws, rotating locking plates, pressing clips, elastic locking plates, and magnetic attraction, all of which can achieve tool-free quick assembly and disassembly.

[0052] Example 5

[0053] The difference between this embodiment and Embodiment 1 lies in the specific implementation of the sealed air duct structure. In this embodiment, sealing strips are provided around the perimeter of the front air inlet mounting plate 31 and the rear air outlet mounting plate 34. After the fan unit 3 is inserted into the chassis body 2, the sealing strips are elastically pressed against the inner wall of the mounting cavity of the chassis body 2, further sealing the gap between the fan unit 3 and the chassis body 2 to prevent air leakage. Alternatively, a guide hood is provided at the air outlet of the fan 35 inside the fan unit 3. The guide hood is connected to the fan outlet on the rear air outlet mounting plate 34 to guide the airflow in a directional manner and reduce turbulence. The remaining structure and working principle are the same as in Embodiment 1. This embodiment shows that a unidirectional sealed air duct can be achieved through various methods such as plate sealing, sealing strips, guide hoods, and labyrinth sealing, all of which can effectively improve airflow utilization and heat dissipation efficiency.

[0054] Example 6

[0055] The difference between this embodiment and Embodiment 1 lies in the insertion and removal direction of the fan unit 3. In this embodiment, the fan unit 3 is assembled to the chassis body 2 by insertion and removal from the bottom up. The mounting cavity of the chassis body 2 is located at the bottom. The fan unit 3 is inserted from the bottom of the chassis body 2 upwards. The guide rail 310 slides and engages with the guide rail groove from the bottom up. The guide pin 36 and the guide pin seat plate 8 are inserted and engaged from the bottom up. The power plug 38 and the speed control feedback plug 37 are simultaneously inserted into the corresponding sockets from the bottom up. The top plate 32 is finally fixed to the top of the chassis body 2 with screws. The remaining structure and working principle are the same as in Embodiment 1. This embodiment shows that the fan unit 3 can be inserted and removed in various assembly directions, such as from the top down, from the bottom up, from the front, the rear, or the side, all of which can achieve the purpose of modular quick disassembly.

[0056] Example 7

[0057] The difference between this embodiment and Embodiment 1 lies in the visualization inspection structure. In this embodiment, a portion of the detachable rear shielding window 4 is made of transparent acrylic sheet, forming a transparent inspection window. The electrical connection status within the plug and socket viewing port can be directly observed without disassembling the detachable rear shielding window 4. Alternatively, the detachable rear shielding window 4 can be hinged to the chassis body 2, forming a flip-up inspection window. After flipping it open, the internal wiring status can be observed. The remaining structure and working principle are the same as in Embodiment 1. This embodiment demonstrates that visualization inspection can be achieved through various structures such as detachable shielding windows, transparent covers, flip-up inspection windows, and pull-out inspection panels, all of which can achieve the technical effect of visually inspecting the wiring status.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
