heat evacuation from an enclosed RP

I'm developing an application using the RP, which is enclosed in a metal case. the case is buried underground, so no ventilation is available. the idea is to evacuate the dissipating heat from the RP to the metal case using a cooling fin (extended surface), and to the surrounding ground. I'm having trouble to predict the temperature of the Zynq CPU, which can't exceed 85 Celsius.
Has anyone tried cooling his RP in a similar manner?
