Description

Technical Field

[0001] This utility model relates to the field of computer equipment, specifically to a VPX air-cooled chassis with a convenient fan removal mechanism. Background Technology

[0002] VPX air-cooled chassis are now widely used in electronic equipment fields, including military, industrial, and communications sectors. VPX air-cooled chassis require long-term stable operation in both harsh and normal environments, placing stringent demands on internal heat dissipation. To ensure stable operation of equipment within the VPX chassis and facilitate subsequent repair and maintenance, adjustments to the internal cooling fan structure are necessary.

[0003] Most VPX air-cooled chassis on the market use built-in fans. In order to ensure that the modules inside the chassis can operate stably under specific ambient temperatures, VPX air-cooled chassis usually select appropriate fans according to the power consumption and temperature requirements of the internal modules. The fans are fixed on the trays or sheet metal inside the chassis, and the power cables of the fans are also pre-tied and routed. In this way, the position of the fans is relatively fixed, and they are installed directly under the chassis and locked together with the beams and trays, making it inconvenient to disassemble and change them.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, a VPX air-cooled chassis with easy fan removal is provided to solve the problem that fans in existing chassis are relatively fixed and inconvenient to remove and change.

[0006] To achieve the above objectives, a VPX air-cooled chassis with convenient fan removal is provided, comprising:

[0007] Chassis body;

[0008] The slide rail assembly includes two outer fixed rails and two inner fixed rails that cooperate with each other. The two outer fixed rails are fixed to the opposite inner sides of the chassis body, and the inner fixed rails are embedded in the grooves of the outer fixed rails to form a telescopic sliding pair.

[0009] A fan support tray is provided with multiple fan mounting positions, and two inner fixing rails are respectively installed on both sides of the fan support tray.

[0010] Preferably, the main body of the chassis includes at least a left cover plate, a right cover plate, a top ventilation plate, a bottom ventilation plate, and a rear cover plate that surround each other; and the outer fixing rail is fixed to the inner side of the left cover plate and the right cover plate.

[0019] The beneficial effects of this utility model are as follows:

[0020] Modular pull-out design: The nested slide rail structure of the outer and inner fixed rails allows the fan support tray to be pulled out from the inside of the chassis as a whole, enabling fan maintenance without disassembling the chassis body, significantly improving disassembly and assembly efficiency.

[0021] Precise positioning and anti-detachment: The combination of the positioning and anti-detachment screws and the inner fixed rail positioning groove ensures the stability of the slide rail extension and retraction, and prevents the tray from completely detaching from the chassis, avoiding the risk of parts falling off due to operational errors.

[0022] Cable management optimization: The cable tray space design between the fan support tray and the bottom ventilation plate, combined with the cable tie positions at the bottom of the tray, enables the orderly arrangement of power cables and signal cables, reducing the impact of cable interference on heat dissipation airflow.

[0023] Double fixing guarantee: The tray is locked to the bottom ventilation plate with fixing screws, and the slide rail limit structure forms a double fixing mechanism to ensure the vibration stability and position accuracy of the fan module during equipment operation.

[0024] Dust prevention and ventilation in tandem: The bottom ventilation plate integrates a dustproof net, which effectively blocks dust while ensuring air intake, extending the service life of the fan, and is especially suitable for dusty environments such as industrial and military industries.

[0025] Human-computer interaction optimization: The dual configuration of the operating handle and the carrying handle structure makes the tray pull-out operation and chassis transportation more convenient; the carrying handle storage sink design takes into account both portability and neat appearance.

[0026] Improved space utilization: The slide rail assembly is located close to the bottom, making full use of the space under the chassis, while reserving ample space for the installation of upper boards, meeting the high-density integration requirements of VPX standard equipment.

[0027] Reduced maintenance costs: Supports independent replacement of individual fans or maintenance of the entire module, reducing downtime, and is especially suitable for high-performance computing scenarios that require frequent adjustments to the heat dissipation configuration.

[0043] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] Reference Figures 1 to 7As shown, this utility model provides a VPX air-cooled chassis with convenient fan removal, including a chassis body 1, a slide rail assembly, and a fan support tray 2. The slide rail assembly includes two outer fixed rails 31 and two inner fixed rails 32 that cooperate with each other. The two outer fixed rails 31 are fixed to the opposite inner sides of the chassis body 1, and the inner fixed rails 32 are embedded in the grooves of the outer fixed rails 31 to form a retractable sliding pair 3. The fan support tray 2 is provided with multiple fan mounting positions 20 for installing fans 24, and the two inner fixed rails 32 are respectively installed on both sides of the fan support tray 2.

[0045] In this embodiment, the chassis body 1 can be any commercially available VPX air-cooled chassis body 1 structure. As a preferred embodiment, the chassis body 1 adopts a convection ventilation chassis structure, which includes at least a left cover plate 11, a right cover plate 12, a top ventilation plate 13, a bottom ventilation plate 14, and a rear cover plate 15 that enclose each other. By enclosing each other to form the chassis body structure, the cover plate structure on any side can be implemented as a transparent plate (such as an acrylic plate). Furthermore, the chassis body 1 also includes a chassis bracket 16, located at the corner of the chassis body 1. The left cover plate 11, right cover plate 12, top ventilation plate 13, bottom ventilation plate 14, and rear cover plate 15 are fixed to the chassis bracket 16. Preferably, the chassis bracket 16 can be made of angle steel strips, and its structure can be assembled with other plates using screws.

[0046] To facilitate the assembly of the fan support tray 2 with the chassis body 1 via the retractable sliding joint 3, two outer fixing rails 31 are fixed to the inner sides of the left cover plate 11 and the right cover plate 12. Furthermore, the retractable sliding joint 3 is located inside the chassis body 1 near the bottom ventilation plate 14; a cable tray space is provided between the fan support tray 2 and the bottom ventilation plate 14 for convenient cable routing. Preferably, cable routing channels (a standard feature) are provided in the cable tray space, at the bottom of the fan support tray 2, and on the sides of the left and right cover plates 12, and cable tie positions 23 are provided at the bottom of the fan support tray 2 for routing and organizing power cables and connecting wires.

[0047] Furthermore, a dustproof net (a standard feature, not shown in the diagram) is also provided on the bottom ventilation plate 14 to prevent dust from entering the main body of the chassis 1 due to air intake from the bottom ventilation plate 14 on the fan support tray 2.

[0048] The fan support tray 2 is pulled out and installed inside the chassis body 1 via a retractable sliding joint 3, creating an installation space for circuit boards and other structures above the fan support tray 2. Furthermore, an upper bracket 42 and a lower bracket 41 are provided inside the chassis body 1 and above the fan support tray 2, with circuit boards installed between the upper bracket 42 and the lower bracket 41. Even further, an upper bracket 44 and a lower bracket 43 for installing a pull-out aid are respectively provided on the upper bracket 42 and the lower bracket 41. The pull-out aid, as a circuit board mounting accessory, is a common structural feature and will not be explained further here.

[0049] To further improve the sliding structure of the fan support tray 2 and achieve anti-detachment and fixed positioning of the fan support tray 2, as a preferred embodiment of this invention, the main body 1 of the chassis is also provided with a limiting and anti-detachment structure, which consists of limiting and anti-detachment screws 33 that penetrate the outer fixed rail 31. The inner fixed rail 32 is provided with a limiting groove 320 along the extension and retraction direction of the slide rail assembly, and the end of the limiting and anti-detachment screw 33 is embedded in the limiting groove 320 to limit the maximum extension stroke of the slide rail assembly.

[0050] Furthermore, the main body 1 of the chassis is also equipped with a fixing structure, which consists of fixing screws 21 that pass through the fan support tray 2; the fixing screws 21 are fixed to the bottom ventilation plate 14. An operating handle 22 is also provided on the outer side of the fan support tray 2 to facilitate the pushing and pulling of the fan support tray 2.

[0051] Specifically, such as Figure 5 As shown, the outer fixed rail 31 is a bar rail with a guide groove, the opening of which faces the inner fixed rail 32. The cross-section of the guide groove is a dovetail groove, a trapezoidal groove, or a convex groove, ensuring that the opening of the guide groove is smaller than the width of the guide groove. Therefore, when the inner fixed rail 32 is inserted into the guide groove, displacement in a non-guided direction can be prevented. Specifically, the inner fixed rail 32 includes at least an insert portion 322 and a mounting portion 321. The insert portion 322 is inserted into the guide groove, and the mounting portion 321 is mounted on the fan support tray 2. The inner fixed rail 32 is an H-shaped bar rail, and the insert portion 322 and the mounting portion 321 are connected by a transverse connecting portion 323.

[0052] As a preferred embodiment of this invention, foot pads are provided at the bottom of the chassis body 1, preferably pin-type foot pads 17, so that an air intake space is formed below the bottom ventilation plate 14.

[0053] As a preferred embodiment of this example, please refer to... Figure 1 and Figure 2This embodiment also includes a handle structure 5, which includes a handle base plate 51, a handle movable shaft 52, and a handle 53; the top ventilation plate 13 is provided with an installation port 130, the handle base plate 51 is installed in the installation port 130, the handle base plate 51 has a storage groove, and the handle 53 is installed in the storage groove through the handle movable shaft 52.

[0054] Fan replacement or removal procedure:

[0055] In its normal state, the fan support tray 2 is tightly attached to the surface of the bottom ventilation plate 14 of the chassis, and the fan support tray 2 is locked with fixing screws 21, so that the entire fan module is inside the chassis. When disassembly or assembly is required, first remove the rear cover plate 15 of the chassis, disconnect the power cable of the fan 24, then remove the fixing screws 21 between the fan support tray 2 and the bottom ventilation plate 14. Grasp the operating handle 22 with both hands and pull it outward. The fan module inside the chassis will move outward with the fan support tray 2. When the handle is pulled outward to its maximum, the fan module is outside the chassis. After removing the screws fixing the fan 24, the fan inside the chassis can be removed. If it is necessary to replace the fan 24 and reroute the cable, remove the limiting anti-loosening screws 33 on the left and right side panels of the chassis, and the entire fan support tray 2 can be completely pulled out from inside the chassis.

[0056] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
