The application discloses a liquid-cooled
server mainboard and a protection method and a liquid-cooled
server thereof, and relates to the technical field of liquid-cooled servers.The method uses
polyolefin material as a waterproof
coating material, divides the mainboard into multiple
processing areas according to functional areas, and makes the waterproof
coating material infiltrate and expand to the root of the device pin and the bottom gap under the capillary effect through glue dispensing to form a bottom
isolation layer, and then forms a top cover layer in at least part of the
processing area.The top cover layer and the bottom
isolation layer are homogeneous materials and the molecular chains are interpenetrated and fused at the interface to form a continuous gradient film thickness structure without an interlayer interface, thereby constructing a complete and continuous physical waterproof barrier on the surface of the mainboard.The method realizes the change from passive post-alarm to active pre-protection, and the
server mainboard can still keep running without
downtime even when the cooling liquid leaks or even immerses the surface of the mainboard, thereby effectively avoiding business interruption and hardware damage caused by liquid leakage.
