A novel technology for thermal control for ISP module for space applications

Thermal control is one of the most important themes in space package technology such as Integrated Sub-system Package technology. At present the technical solutions reducing heat stagnation are thermal dissipation and thermal cooling. In this paper a novel approach to increase thermal dissipation, based on the use of the pyroelectric materials, is proposed. The pyroelectric materials are able to convert the thermal energy into electric energy spontaneously. This characteristic is employed to increase thermal flux inside the microelectronic units and to reduce the thermal overstocking. In order to evaluate the temperature distribution inside the component a numerical evaluation of the transient thermal problem inside a multi-layered wall electronic device is performed and a preliminary design of an adaptive dissipation device based on pyroelectric material is presented.
