Liquid cooling eases data centre heat

05 August 2008

Over half of the energy consumed by data centres is cooling the equipment, making efficiency a priority.

Liquid cooling packages from Rittal are claimed to solve the high density heat issues up to 70kW and also improve cooling efficiencies and so reduce energy costs. The company claims that cooling can be free for nearly 70 per cent of the year within the UK, using these LCPs (liquid cooling packages).

The environmentally controlled chambers can be fitted as an extension to the rack or inside the rack and are capable of removing over 30kW of heat. Alternatively, two systems either side of a rack can provide an even distribution of chilled air at a more even temperature than conventional cooling. It also has the benefit of freeing up internal space.

Microelectronics monitor the system and are based on a series of environmental and heat load measurements. The LCPs also include leak detection, which activates an alarm and can isolate the affected rack system and trigger a ‘dump’ mechanism in <3secs.

The company also supplies server and remote monitoring, with the Rittal Computer Multi-Control (CMC), which allows doors to be locked. Features include smoke detection, vibration detection, temperature monitoring, real-time web-cam, and monitoring of fan RPM and water flow. Racks and LCP systems can be monitored from any location via the web.
