Data center with dual radiator cabinets for redundant operation

摘要

Methods of preventing overheating of computer equipment in a cabinet when a supply coolant to a cooler in the cabinet fails. An example embodiment is a data center that includes a plurality of cabinets and at least two main coolant supply lines. The cabinets are configured to house computer equipment and the main coolant supply lines provide coolant to the plurality of cabinets. Moreover, each cabinet includes a cooler and each of these coolers includes at least two radiators which receive coolant from different main coolant supply lines.

1. A method for preventing the overheating of computer equipment in a cabinet, the cabinet including at least two radiators for cooling exhaust air, the method comprising:
coupling a first radiator in the cabinet to a first main coolant supply line and a second radiator in the cabinet to a second main coolant supply line, each of the first main coolant supply line and the second main coolant supply line supplying coolant to a plurality of cabinets; comparing a first temperature difference between a first front temperature sensor positioned at a front side of the first radiator and a first back temperature sensor positioned at a back side of the first radiator; and comparing a second temperature difference between a second front temperature sensor positioned at a front side of the second radiator and a second back temperature sensor positioned at a back side of the second radiator; detecting a leak in one of the first main coolant supply line or second main coolant supply line by detecting one of the first temperature difference or the second temperature difference is below a threshold value; activating the first louvers to block airflow through the first radiator while the second set of louvers remains open to allow exhaust air to flow through the second radiator and computer equipment if the detected leak is in the first main coolant supply line; and activating the second louvers to block airflow through the second radiator while the first set of louvers remain open to allow exhaust air to flow through the first radiator and computer equipment if the detected leak is in the second main cooling line.
