Description
Technical Field
[0001] This invention relates to the field of electromechanical equipment technology. Background Technology
[0002] Existing VPX chassis generally use only a single card slot or fixed slot design, which cannot meet the high integration requirements of multiple modules working in parallel, and there is signal interference between different modules. Furthermore, due to the overall structure being unfavorable for heat dissipation, it is easy to cause airflow obstruction and heat dissipation blind spots. There is a serious problem of high-power heat generation caused by highly integrated modules. During use, dust will inevitably accumulate in the ventilation holes, making it difficult to clean, and the heat dissipation efficiency will decrease after long-term use. Summary of the Invention
[0003] The purpose of this invention is to provide a portable VPX chassis that effectively solves problems such as insufficient integration flexibility, cumbersome disassembly and assembly, and unreasonable heat dissipation structure.
[0004] To solve the above-mentioned technical problems, the present invention provides a portable VPX chassis, including a chassis body, which is a rectangular frame structure with front and rear openings. The chassis body is divided into front and rear parts by a horizontal back panel. A longitudinal partition is fixed to the front of the back panel inside the chassis body. Each partition has a strip hole for ventilation. Side ventilation holes are opened on the left and right side walls of the chassis body. A fan module is fixed to one side of the chassis body against the inner wall.
[0005] The longitudinal partition is equipped with guide rails.
[0006] The box contains multiple rectangular module guide slots located at the rear of the back panel.
[0007] The front end of the box is equipped with an openable front cover, and an operation panel is mounted on the side of the front cover.
[0008] The top surface of the box is fixed with an upper cover plate, and the bottom surface of the box is fixed with a lower cover plate.
[0009] The front two sides of the box are integrally provided with handles.
[0010] Pull-out aids and pull-out supports are installed on the top and bottom edges of the rear end of the housing.
[0011] The rear end of the enclosure is equipped with a VPX power supply and an RF power supply board.
[0012] The enclosure has a detachable air inlet plate on one side wall with side ventilation holes, and the other side wall is a detachable air outlet plate with a shielding window fixed to the fan module.
[0013] The guide rail has a slotted hole in the middle for ventilation.
[0014] Compared to existing technologies, this invention divides the enclosure into front and rear sections using a horizontal back panel. The front section accommodates various functional modules via longitudinal partitions and guide rails, while the rear section utilizes multiple rectangular module guide slots specifically for deploying VPX modules. The power supply and RF power supply boards achieve physical partitioning and independent layout of functional modules and power modules. One side of the enclosure has a removable air intake panel, and the other side has a fully removable air exhaust panel. Combined with the front cover that can be opened and closed, it breaks the limitation of traditional VPX enclosures that require the removal of multiple cover panels to inspect internal components. At the same time, the pull-out aids and pull-out brackets at the rear solve the problem of disassembly difficulties caused by uneven force during module insertion and removal, enabling quick removal or installation of modules and significantly shortening maintenance and replacement time. A multi-level ventilation path is constructed, with strip holes in the middle of the longitudinal partitions and guide rails. Combined with the side ventilation holes on both sides of the enclosure, airflow can penetrate the core heat-generating parts of the module installation area. In addition, the corresponding arrangement of the fan module and the air exhaust panel forms a directional airflow channel from the air intake panel, through the surface of each heat-generating module, and finally discharged from the shielding window by the fan module. This avoids heat dissipation blind spots caused by airflow obstruction, and provides more comprehensive heat dissipation coverage, which can effectively cope with the high-power heat generation problem brought by highly integrated modules.
