Question

Consider a 18-mm by 18-mm chip that is cooled on its top surface by a 6 m/s flow of 25 ºC air. Any heat transfer from its bottom surface to the circuit board is ignored. Because of the chip construction, the electrical power dissipated in the chip results in a uniform heat flux over the surface of the chip. If the maximum temperature that any part of the chip can experience is 85ºC, determine the maximum allowable chip power. Note: the air properties can be determined at the ‘film" (or average) temperature.

Answer 2

Answer:

Explanation:

Length (l) = 10

Width (w) = 10

Velocity =

Ambient Temperature = 25 degrees Celsius

Surface Temperature = 85 degrees Celsius.

Note these values as what we will use to solve for the maximum allowable chip power, then go through the attached files for a step by step explanation of how the answer is gotten.
