Abstract

This disclosed concept proposes an option of measurement kit having varies sensors along with Rear Door Hear Exchanger doors (Also termed as RDHx doors) for modern Data Centers (also termed as DC). This kit enables DC manager’s to achieve enhanced, safe optimal performance of RDHx doors by providing visibility into gradient temperature for zones and any deviation of water pressure and flow.

Thermal measurement kit for water based Rear Door Heat Exchanger ( RDHx)h*

The growth of computer networking and particularly the rapid growth of the high computing resource for myriad business applications have resulted in a rapid increase in demand for server computers. Most commonly these server computers are housed in 19 inch racks. Typically a large number of such racks are housed in a building known as a data centre. In a data centre, one or more large rooms are provided. Each room houses rows of IT equipment racks and, associated cabling and network communication equipment. A modern rack when fully loaded with servers consumes a large amount of electrical power when operating. As consequence, a large amount of waste heat is produced. Many data centres now employ racks of 10 to 25kW to achieve enormous computing power in a smaller footprint, these racks develops equivalent or a little less of waste heat. To avoid damage to the servers by overheating, this waste heat must be removed. In a commonly used arrangement, data centre rooms are cooled by computer room air conditioning units. However, soaring energy prices have forced DC managers to adopt alternative cooling techniques such as water based Rear Door Exchangers. NOTE: Water is much efficient then air to remove the heat energy.

Fundamentally RDHx door are passive devices and uses water to remove the heat generated by IT racks before it mixes up with DC ambience. The RDHx doors are being used for additional cooling in typical data center environments. Chilled water is streamed through RDHx pipes (doors) with constant pressure and temperature. The water pipes reduce the passing through air temperature by at-least 70% as claimed via product features. However, existing RDHx working methodology is to operate as stand-alone also does not provide first hand view of its efficiency and optimal usage. This becomes a critical factor for dynamic data centers (meaning frequent a...
