US Patent 11076505 Cooling system for edge computing device

According to one embodiment, an edge cooling system with an IT container having an edge device partially submerged within a liquid coolant. The device generates heat that is transferred into liquid coolant thereby causing the liquid coolant to vaporize into vapor. The system includes a condenser that condenses vapor into liquid coolant, a vapor buffer configured to buffer and provide vapor to the condenser, a liquid accumulator configured to accumulate condensed liquid coolant and provide liquid coolant to the IT container, a main liquid supply line that couples the condenser and IT container to the liquid accumulator, and a main vapor return line that couples the condenser and IT container to the vapor buffer to create a heat exchanging loop. The system design includes the liquid accumulator and vapor buffer, and functions multiple cooling modes including a supplemental cooling. Each of the components are fully enclosed within an edge container.
