You are actually pretty close.  If you want to equate thermodynamics to 
electronics, temperature equates to voltage and temperature difference 
equates to voltage difference, heat flow equates to current, thermal 
resistance equates to electrical resistance.  Use the right units and 
ohms law works with heat transfer.  BTW mass equates to capacitance.
