Abstract

An electronic rack includes a rack manifold having a rack liquid supply line and a rack liquid return line, and server blades arranged in a stack. Each server blade includes cold plates and a server liquid distribution loop, and a leak detector configured to detect leaking of the cooling liquid distributed to the server blade. The electronic rack further includes server FCDs corresponding to the server blades and an RMC unit coupled to the server FCDs and leak detectors of the server blades. In one embodiment, in response to a signal received from a first leak detector of the first server blade indicating that there is a leak within the first server blade, the RMC unit is configured to transmit a control signal to the first server FCD to reduce an amount of cooling liquid to be distributedto the first server blade or bypass the liquid completely.

Description

technical field [0001] Embodiments of the invention relate generally to data centers. More specifically, embodiments of the invention relate to liquid distribution unit designs for liquid cooling of electronics racks in data centers. Background technique [0002] Heat dissipation is an important factor in computer system and data center design. The number of high-performance electronic components, such as high-performance processors packaged inside servers, has steadily increased, increasing the amount of heat generated and dissipated during normal operation of the server. The reliability of servers used in a data center decreases if the environment in which the servers are allowed to operate increases in temperature over time. Maintaining a suitable thermal environment is critical to the proper operation of these servers in the data center, as well as server performance and longevity. This requires more effective and efficient cooling solutions, especially in cooling the...
