Cooling plate for server electronics with two-phase fluid cooling
A recently granted patent (Publication Number: US11968803B2) discloses a cooling plate designed for server electronics cooling. The cooling plate features an inlet port for receiving a two-phase fluid from a cooling source, a base plate for attachment to server electronics, heat spreading structures on the base plate to extend the heat exchange area, and fluid channels inserted between the heat spreading structures. These fluid channels have inlet and outlet ports, along with intermediate outlets for the two-phase fluid to exit either in vapor or liquid form. The design aims to efficiently cool server electronics by maximizing heat exchange through the innovative layout of heat spreading structures and fluid channels.
Moreover, the patent also covers a server enclosure incorporating the cooling plate design. The server enclosure includes supply lines, fluid supply connectors, a server chassis for housing electronics submerged in a two-phase immersion fluid, and the cooling plates within the chassis. The cooling plates, similar to the standalone cooling plate, facilitate the transfer of the two-phase fluid to cool the server electronics effectively. The system's design ensures optimal cooling performance by strategically placing the fluid channels between the heat spreading structures, enhancing heat dissipation and overall efficiency. Additionally, the inclusion of a temperature sensor to control the pump managing the fluid flow further enhances the system's cooling capabilities, making it a comprehensive solution for efficient server cooling within an immersion environment.
