AI Technical Summary
The separate layout of circuit boards and power supplies in existing chassis leads to insufficient space utilization, increases chassis size, and makes it impossible to flexibly configure the number of circuit boards.
A cabinet structure is provided, which enables flexible layout of boards and power supplies through detachable mounting brackets and multiple mounting positions. It supports multiple configuration modes, including non-full configuration multi-channel and full configuration multi-channel layouts. Combined with heat dissipation and cable management design, it optimizes space utilization.
Without increasing the chassis size, the number of boards can be flexibly configured to meet the needs of different application scenarios, improve space utilization and aesthetics, and ensure stable power supply.
