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...

Analyzing a Fin Consider an infinitely long fin with a square cross section with 5mm. The base of the fin is held at a fixed temperature of To = 100°C and air is passing by the fin at T = 20°C with a convective heat transfer coefficient of h - 55 W/m-K. The fin is made from aluminum with a thermal conductivity of k- 180 W/mK. T. = 20°C n...

Consider the base plate of a 1200-W household iron that has a thickness of L = 0.5-cm, base area of A= 300-cm', and thermal conductivity of k = 15-W/m-C". The inner surface of the base plate is subjected to a uniform heat flux generated by the resistance heaters inside, and the outer surface losses heat to the surroundings at T = 20°C by convection. Taking the convection heat transfer coefficient to be h = 80-W/m--°C obtain an expression for the...
