Don't talk much . First question A heat conduction problem with heat source term .

① First of all , Because given the exothermic watt （ Joules / second ） Is a constant that does not change with time . Good to consider ,

② second , Because the length of this chassis is 12 rice , And the diameter is only 1 rice , Directly reduced to one dimension （ A two-dimensional ） Heat transfer equation ,（ Don't bully me , With your strength , Just a few days. , Three dimensions are not solvable , If you don't believe it, try ）

therefore , First, make the curve of the central temperature of the chassis changing with time , Reanalyze the heat source （ This heat source is a constant , Don't put it in the equation , Of course, you can put it in ~）

 

③ Third , Consider a steady state , Is to keep 80 Chassis temperature balance of degrees , So let's assume that the initial temperature is 80 degree , Let's first look at the cooling of the chassis .

As you can see, over time Temperature by 80 The degree gradually drops to 20 degree ....
