Cooling of Chips in Circuit Boards Problem One way to cool chips mounted on circuit boards is to encapsulate the boards in metal frames that provide efficient pathways for conduction to supporting cold plates.
T = 32 Celsius
Circuit Board Frames. T=47 Celsius, N=10
Circuit Board Containing Chips
With a total of N = 10 passages, the total heat dissipation is
To find how much of the heat generated by the circuit boards is transferred to air.
2,670W 9.5 percent(low) Heat Transfer to the Air
