Abstract

The liquid cooling system has several liquid cooling units (4) in a rack (2) or cabinet and associated with individual electronic units (1) and a monitoring and control device (9) for monitoring the cooling temperature. The cooling units are connected via branch points (5.1) to a common central liquid cooling system (5) integrated into the rack or cabinet.
