AI Technical Summary
After the equipment frame is disengaged from the coolant, the existing air-mounted liquid cooling box only relies on leaks and air-drying to dry, which takes a long time and leads to an increase in maintenance time.
An airborne sealed liquid-cooled chassis including a lifting mechanism and an auxiliary drying mechanism is designed. The lifting mechanism realizes the rise and fall of the equipment frame through the transmission screw and the motor, and the auxiliary drying mechanism uses the meshing effect of the synchronization wheel and the synchronization belt to achieve heat guidance and accelerated flow of coolant by linking the auxiliary drying assembly and the electric heating plate.
By accelerating the flow of coolant and the conduction of heat, the drying time of the electronic equipment surface is significantly shortened and maintenance efficiency is improved.

However, due to the increase in the number of components, the power density and heat flux density of electronic equipment have increased significantly, heat is concentrated, and the local temperature is too high. If the heat is not dissipated in time, it will cause the performance of the electronic equipment to decline or even crash.

[0004] When the above-mentioned airborne closed liquid-cooled chassis is in use, after the equipment frame is lifted up and separated from the coolant with the related electronic equipment in the chassis through the screw drive, it only relies on the leakage from the leakage holes at the bottom of the equipment frame and air drying to dry the coolant around the electronic equipment. However, this drying process takes a long time, thereby increasing the maintenance time. For this reason, we propose an airborne closed liquid-cooled chassis. Utility Model Content
