DIPLOMAT Case Cooling
NEW AND IMPROVED COOLING PERFORMANCE
The DIPLOMAT range of enclosures has improved cooling performance in both
the standard and fan plinth versions. The fan plinth version has a wider plinth
with an increased ventilation surface area to increase the volume of air flow. The
plinth can either act as a chamber for air collection when fans are mounted on
the rear panel of the unit (pull through air flow) or can be used to mount fans
directly hence employing a push method of cooling. Fans can be mounted in the
plinth and on the rear panel employing a push-pull method of cooling.
Ducting plates can be placed in the plinth to give additional direction to the
air flow, concentrating the flow towards hot cards or components. The level
of cooling performance achieved will depend on a number of variables, such
as the internal component architecture and hot component positioning. A test
was set up where a 6U DIPLOMAT unit 19" wide was fitted with a populated
card frame, 220mm boards to a 6U full width backplane, and air flow indicating
componentry. Two 95CFM fans were mounted on the rear panel and a standard
ducting plate used to direct the air across the cards, the results recorded are
shown below.
The results below were measurements of air velocity taken from the standard
DIPLOMAT with new 38mm deep plinth with ducting plate, and 2 x 95 CFM fans
mounted on the rear panel. The top panel was non ventilated.
