large scale microelectronic chip,
A simplified
representation for cooling in very large-scale integration (VLSI)
of microelectronics is shown in the sketch below. A silicon chip is
mounted in a dielectric substrate, and one surface of the system is
convectively cooled, while the reminding surfaces are well
insulated from the surrounding. The problem is rendered two
dimensional by assuming the system to be very large in the
direction perpendicular to the paper....

Part 2 - Problems (75 marks) I. Copper fins (k 401 W/mK) of uniform square cross-section (2mm x 2mm) and length L 30mm are used in a fin array to enhance heat transfer from a 40mm x 40mm surface that is maintained at Tb 170°C. There are a total of 100 fins, and the tip of the fins is maintained at 35°C. Air circulates over the fin array with a temperature of To = 15°C and a convection coefficient of...

The heat that is conducted through a body must frequently be removed by other heat transfer processes. For example, the heat generated in an electronic device must be dissipated to the surroundings through convection by means of fins. Consider the one-dimensional aluminum fin (thickness t 3.0 mm, width 20 cm, length L) shown in Figure 1, that is exposed to a surrounding fluid at a temperature T. The conductivity of the aluminum fin (k) and coefficient of heat convection of...
