This utility model discloses a two-phase flow cooling chassis for airborne electronic equipment, including a chassis body. The chassis body includes a front insertion processing module, a lower cooling plate, a right side cooling plate, an upper cooling plate, a left side cooling plate, and a rear insertion interface module.

This utility model discloses a light strip control device, including a control box. A controller is fixedly connected to the center of the inner side of the control box, and a first wire is fixedly connected to one side of the outer surface of the controller. A connector is fixedly connected to the end of the first wire away from the controller. This light strip control device, through the arrangement of a connector, clamping arm, connecting rod, and a first spring, allows the clamping arm at the connecting rod to rotate and unfold under the support of a support plate. The first spring is compressed, inserting the light strip interface into the connector. This eliminates the need for welding or complex wiring, significantly shortening installation time. Releasing the clamping arm, under the action of the first spring, causes the connecting plate and connecting rod to reset the clamping arm. The clamping arm limits the light strip interface, preventing the light strip from accidentally detaching from the connector due to external pulling during use. This avoids electrical short circuits, leakage, and other safety hazards caused by the light strip falling off, ensuring long-term connection stability and providing convenience for disassembly and assembly.
