Problem 3.142

Finned passages are frequently formed between parallel plates to enhance convection heat transfer in compact heat exchanger cores. An important application is in electronic equipment cooling, where one or more air-cooled stacks are placed between heat-dissipating electrical components. Consider a single stack of rectangular fins of length L and thickness t, with convection conditions corresponding to h and T. (a) Obtain expressions for the fin heat transfer rates, qf,o and qf,L, in terms of the base temperatures, To and TL. (b) In a specific application, a stack that is 200 mm wide and 100 mm deep contains 50 fins, each of length L 12 mm. The entire stack is made from aluminum, which is everywhere 1.0 mm thick. If temperature limitations associated with electrical components joined to opposite plates dictate maximum allowable plate temperatures of To 400 K and TL 350 K, what are the corresponding maximum power dissipations if h 150 W/m2 K and T 300 K?

DAY 1 Coding Vocab Syntax:​ The set of rules that defines the combinations of symbols that are considered to be a correctly structured document or fragment in that language (set of rules that govern how things are done) Command: ​ An instruction to a computer or device to perform a specific task Variable: A storage location paired with an associated symbolic name (an identifier), which contains some known or unknown quantity of information (a name we associate with some sort of data so MATLAB knows that, for example, a=15, and it’ll know every time we put “a”, it is 15. It is storing things we need in a variable.) Comment:​ A line of text (command) that will not be executed but it’s there to help you understand more. Add at the end and put a % sign. Function:​ A specia
