Abstract：An explosion-proof shell with natural convection heat dissipation was designed for a certain electronic device with high heat generation that needs to be used underground in coal mines.It can quickly transfer the heat of electronic devices inside the explosion-proof shell to the finned radiator substrate through heat pipes,and then transfer the heat to the fins outside the explosion-proof shell through heat conduction.The fin and the surrounding air convection heat transfer heat.The temperature distribution of air between fins of a finned radiator was analyzed using icepak software at different fin spacing,and the performance of the finned radiator was optimized.The feasibility of the design was verified through simulation.
