    3 Device description Device description General functional description The Liquid Cooling Package DX (DX = Direct Expansion) is essentially a split air conditioning unit used to dissipate high heat losses from server enclosures or for the effec- tive cooling of devices built into a server enclosure. The air routing in the LCP DX supports the "front to back"...

  • Page 10: Lcp Rack Dx

    3 Device description In order to ensure targeted air routing in the system, the server enclosure should be divided vertically into warm air and cold air sections. The division is accomplished in the front section of the server assembly to the left and right of the 482.6 mm (19") level using foam strips or air baffle plates which, depending on the enclosure width and the number of server enclosures to be cooled, can...
