US Patent 11317543 High power density based two phase system design

A cooling system can include an input channel from which a fluid enters the cooling system and an output channel from which the fluid exits the cooling system. The cooling system can include a vapor buffer and a liquid buffer, and the connections between the two buffers. Vapor buffer valves arranged in fluid channels of the cooling system can be controlled to, in a first mode, disconnect the vapor buffer from an input channel, and, in a second mode, connect the vapor buffer to the input channel and disconnect the vapor buffer from the input of the condenser or the port that is attachable to the input of the condenser.
