Abstract
A leak protection system deflects leaking water away from the rack-mounted critical systems and detects and reports the existence of a leak. In embodiments, this is accomplished without compromising access to or visibility of the critical systems or thermal management of heat dissipated by the critical systems. In embodiments, the leak protection system produces a minimalist visual footprint with limited impact on the aesthetics of the rack-mounted critical systems and data center.

A leak protection system for use with a rack-mounted critical system having an overhead cabling structure for routing cabling, said system comprising:
- a panel mounted above the rack-mounted critical system and cabling structure at an angle with a highest point that overhangs the back of the rack towards a hot aisle above the cabling structure and a lowest point that overhangs the front of the rack towards a cold aisle to deflect water that runs down the panel towards a front edge, said panel angled to allow access to the cabling and to direct rising heat out of the back of the rack-mounted critical system to the hot aisle;
- a raised lip that runs along the front edge of the panel at the lowest point to form a water channel to collect water;
- a water detection system positioned in and along the water channel to detect the presence of water and to issue a leak alert;
- and
- a gap in the water channel to evacuate the collected water.
A leak protection system, comprising:
- multiple rows of rack-mounted critical systems, each row including multiple rack-mounted critical systems positioned side-by-side, said racks generating heat that rises through the top of the rack, said rows separated by alternating hot and cold aisles;
- a cabling structure above each row for routing cabling to the racks;
- one or more panels mounted side-by-side above each row and the cabling structure at an angle with a high point that overhangs the back of the rack towards the hot aisle above the cabling structure and a low point that overhangs the front of the rack toward the cold aisle to deflect water that runs down the panel towards a front edge, said panel angled to allow access to the cabling and to direct the rising heat out the back of the rack to the hot aisle, said panel formed from a clear transparent acrylic material to allow overhead light through the panel to provide visibility of the cabling and rack-mounted critical systems while limiting the visibility of the panel;
- one or more raised lips that run along the front edge of the one or more panels at the low point to form a water channel to collect water in each said row;
- multiple water detection systems each comprising a water detector positioned in and along the water channel to detect the presence of water and a sensor that monitors a change in state of the water detector to issue a leak alert;
- one or more gaps in the water channel to evacuate the collected water;
- and
- a single sensor aggregator port responsive to the leak alert from said water detection systems for said multiple rows to generate and transmit a leak alert notification.
