If you are thinking about heat conduction in the aluminum, it can be tricky. If you only need the shielding capabilities of the aluminum, try a baffle with thermal resistance.

Thanks Joan.. there is not only heat conduction, also we are thinking about radiation effects.. and radiation coefficients of this layer also important for this problem.. i will try to use baffle interface.. thanks a lot..
