Description

Technical Field

[0001] This utility model relates to the field of VPX chassis technology, and in particular to a 5U VPX chassis. Background Technology

[0002] With the surge in demand for high-performance computing and high reliability in military electronic equipment, aerospace, and industrial automation, traditional VPX chassis architecture faces severe challenges. Due to the increased power density of VPX boards (such as GPUs / FPGAs), traditional air cooling is inefficient. Most 5U VPX chassis currently use natural cooling, which has limited heat dissipation capacity and is greatly affected by ambient temperature. This leads to a decline in the performance of power supplies and boards, and board components are prone to damage when exposed to high temperatures for extended periods. At the same time, the fixed structure is difficult to accommodate the mixed insertion of multiple types of boards, and replacing faulty modules requires system shutdown and disassembly, affecting system availability. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a 5U VPX chassis.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A 5U VPX chassis includes a chassis body, a heat dissipation module, and a board support bracket. The heat dissipation module includes an exhaust module mounted on the top of the chassis body from bottom to top, an air supply module mounted on the rear of the chassis body, and air supply holes on both sides of the chassis body. The chassis body is fixed with a crossbeam with slide rails. The board support bracket is mounted on the slide rails.

[0006] Furthermore, the enclosure includes a top panel, a bottom panel, a left side panel, a right side panel, a front panel, a rear panel, and a middle panel. The front panel is hinged to cover the plug-in door panel. The middle panel is provided with ventilation holes and is arranged parallel to the front panel and the rear panel. Both the middle panel and the front panel are fixedly provided with two upper and lower crossbeams.

[0007] Furthermore, a handle is provided on the front panel.

[0008] Furthermore, the slide rail is provided with a positioning component and a moving component; the moving component is connected to the board bracket, allowing the board bracket to move on the slide rail; the positioning component is used to fix the moving component.

[0009] Furthermore, the air supply module is located on the right side of the rear panel, and the exhaust module is located in the middle of the upper panel.

[0010] Furthermore, a heat spreader is provided on the back of the board bracket.

[0011] Furthermore, the housing, board bracket, and slide rail are all made of 6061-T6 aluminum alloy with surface treatment.

[0012] This utility model has the following beneficial effects: This utility model increases the heat dissipation, compatibility and flexibility of the chassis through layered board thermal management and dynamic expansion structure. Forced convection at the top and heat dissipation plate on the back of the board achieve chip-level directional heat dissipation, which reduces the temperature by more than 15°C compared with traditional solutions. At the same time, the design is a sliding rail type chassis, which allows the chassis to flexibly mix and match various types of boards. Attached Figure Description
