TITLE : HOTBOX EXAMPLE - HEAT DISSIPATION IN A DATA-COMMUNICATIONS COLLECTION BLOCK

BY : CHAM Development Team - D Radosavljevic
FOR : Northern Telecom Europe Ltd.
DATE : 1992
PHOENICS Version : HOTBOX 1.6

DETAILS :

• Two-Dimensional Steady-State flow
• Cartesian Computational grid

NOTES :

• Example of how a heat bridge can be used to significantly enhance heat transfer between two separate components.
• Heat is transferred by natural convection between the Heat Source and a heat-sink across the air gap between them.
• WITHOUT heat bridge RESULT : Block over-heated to 165 C.
• WITH heat bridge RESULT : Block cooled to 85 C.

Pictures are as follows :
