An expansion surface heat transfer formula is given as follows.
hot (Rx)- Too)=0
Based on the boundary conditions above, four temperature
distribution formulas and heat transfer rates can be obtained as
shown in Table 2.1. Here, when the boundary condition is the
second case of insulation at the end of the fin, the boundary
condition is given as follows.
I
boundary condition 1) (0) -9.
2)
de
At this time, induce the temperature distribution and heat transfer
rate of the fin from the boundary condition.
(To induce the equation below.)
