• Design of a new calorimeter for measuring heat power loss in electrical components.
• The calorimeter can operate in a temperature range from −50 °C to 150 °C.
• An analytical model of heat transfers for this new calorimeter is presented.
• The theoretical sensibility of the new apparatus is estimated at ±1 mW.
This paper deals with an analytical modeling of heat transfers simulating a new radiation calorimeter operating in a temperature range from −50 °C to 150 °C. The aim of this modeling is the evaluation of the feasibility and performance of the calorimeter by assessing the measurement of power losses of some electrical devices by radiation, the influence of the geometry and materials. Finally a theoretical sensibility of the new apparatus is estimated at ±1 mW. From these results the calorimeter has been successfully implemented and patented.
