TITLE : HOTBOX EXAMPLE : CIRCUIT-BOARD COOLING IN AN ELECTRONICS CABINET (Library Case : 106)

BY : CHAM Development Team - D Radosavljevic
FOR : Demonstration Case
DATE : 1990
PHOENICS Version : HOTBOX 1.6

DETAILS :

• Three-Dimensional, Steady flow
• Cartesian computational grid

NOTES :

• HOTBOX predicts the temperatures and velocities in the cabinet from information about the heat sources and the fan characteristics
• Cooling of 12 Chips dissipating heat on 2 PCBs
• Air enters the cabinet through an inlet fan at 5 m/s
• The inlet-air temperature is 25 Degrees
• The air freely exits the cabinet through an outlet duct
