Respected experts,
1). My system is a heat generating part present at the centre.
2). Above the heating part, there is a fin for heat dissipation.
3). Internally, there is only air between the side covers and the system.
4). Some amount of energy dissipates to the side covers through convection at the internal volume.
5). It is natural convection. Not forced convection.
Please help me in solving this computation.

Thanks!
