Rittal DCP – A system solution for optimum cooling of drives and power electronics within enclosures. A new standard in switchgear and control system engineering. Liquid-cooled partial mounting plates with pressed-in copper or stainless steel tubes on their reverse face, integrated into closed loop chiller systems or an existing water circuit. With Rittal partial mounting plates, installation into the TS 8 top enclosure system is child's play with a system for installing accessories at 25 mm intervals. At the same time, however, a 4-point attachment facility permits direct mounting on the mounting plate or any other surface. Drive components can be cooled more effectively by way of the liquid cooled DCP mounting plate (Direct Cooling Package). Heat losses are dissipated from the enclosure or housing without compromising a high enclosure protection category in any way. Furthermore, liquid cooling is both quiet and 1000 times more efficient than heat dissipation via air.

Three dimensions of drive cooling Rittal system integration: Enclosure + mounted drive + climate control components 1. Conventional installation The simplest form of installation: The drive is mounted directly on the mounting plate of the TS 8 top enclosure system. The fans of the drive draw cool air from the lower section of the enclosure and establish a flow over the heat sinks of the drive. The warmed air is returned to the enclosure interior. The cooling output required for the whole enclosure is provided by air conditioners, air/water heat exchangers and other Rittal climate control components. Higher heat loads are dissipated most effectively via air/water heat exchangers in combination with an externally installed recooling system. This configuration avoids unnecessary heating of the ambient air.

2. New solutions for pass-through technologies An interesting alternative – and cost-effective: Where the ambient air is cool and clean, pass-through solutions are a very efficient means of removing a significant proportion of the heat losses from the enclosure, when the drives and other heat providing equipment possess protruding heat sinks. Solution 1: A sealing frame between a cut-out in the rear panel of the enclosure and the mounting plate. Solution 2: Blanking panels replace the original rear panel and close the space between the enclosure frame and mounting plate. If necessary, the heat loss remaining in the enclosure can be dissipated by way of air/air heat exchangers, fan-and-filter units or other climate control components.

3. Direct cooling package Keep a "cool head": Rittal DCP – the fluid-cooled partial mounting plate represents the new standard for the effective cooling of drives and power electronics. Compatibility with the TS 8 partial mounting panel installation system saves time and money. Even high degrees of enclosure protection are in no way impaired by the DCP Cold Plate. Some 70 – 80 % of the heat loss of the drive is dissipated to the chilled water – absolutely quiet and directly from the source. With the appropriate configuration, it may be possible to completely eliminate the need for other cooling solutions.
