TUCKER Ga., 6 Dec. 2006.Optima EPS, an Elma Company in Tucker, Ga., is announcing a cabinet enclosure designed for MicroTCA applications.
The modular cabinet features a stacked arrangement of open card cages, fan trays, and heat exchangers. Without top or bottom covers, the open card cages allow air to flow through several stacks of MicroTCA shelves.
The fan trays and heat exchangers cool the cabinet in this modular configuration. Various implementations of card cage shelves, fans, and cooling units can be configured in the cabinet.
The MicroTCA 19-inch cabinet is designed according to ETSI 300-119-3 with a 44U height, 750 millimeters wide, and 300 millimeters deep. The unit accepts 10 MicroTCA single-width subracks, accepting 120 full size modules or 240 compact modules plus power modules dissipating a total of approximately 6 kilowatts in a closed-loop heat exchanger concept.
MicroTCA shelves interleave with heat exchangers and fan trays. The heat exchangers require an external chiller unit. The typical shelf temperature rise is 15 degrees Celsius while the heat exchangers are able to provide a temperature drop of approximately 15 C.
This solution allows for high-density cabinet packaging and provides the following advantage extreme low noise, EMI containment (at closed cabinet level) and maximum possible cable routing space/management. For more information contact Elma online at www.elma.com.
