Server rack with leak protection and detection
A liquid cooling system can be installed to an information technology (IT) rack. The liquid cooling system can include a cooling assembly that has a cooling chassis and cold plates fixed at a bottom portion of the cooling chassis. Fluid lines are arranged in an interior of the cooling chassis to fluidly connect the cold plates to a supply line and a return line. The cooling chassis includes an outlet port that provides a path for a leaked fluid to flow out of the cooling chassis. The outlet port is inserted into an opening of a detection channel that has one or more fluid sensors within the detection channel. The floor of the cooling chassis may have a shape or other features to assist flow of leaked fluid towards the outlet port to assist in depositing the leaked fluid in the detection channel.
