The paper presents two electro-thermal numerical models which can be used for the modeling and optimization of high currents busbar contacts for DC. The models are obtained by coupling of the electric model with the thermal field problem. The coupling is carried out by the source term of the differential equation which describes the thermal field. The models allow the calculation of the space distribution...
Thermal interface resistance of solids is an important factor for heat conduction from one solid to another. Interface resistance disrupts heat flow in systems like CPUs and various solid state devices like LEDs. Interface materials play an important role in heat transport through interface. In this study, Al203 with different thickness was coated on a copper substrate. The overall thermal conductivity...
Thermal interface resistance of solids is an important factor for heat conduction from one solid to another. Interface resistance disrupts heat flow in systems like CPUs and various solid state devices like LEDs. Interface materials play an important role in heat transport through an interface. In this study, TiN/Ti with different Ti thickness and Ti/TiN was coated on a copper substrate. In general...
A thermal interface material (TIM) with the highest thermal conductivity does not automatically deliver the best thermal management performance. It is just as important to achieve the best surface contact between TIM and various substrates. Softer interface materials like silicone gap fillers tend to lower contact resistance and thermal impedance. More importantly, the low modulus of silicone gap...
Solid thermal interface materials are often used in thermal reliability tests of IC packages to minimize contact thermal resistance without contaminating the test environment. In this paper, thermal characterizations of solid thermal interface materials, including indium, graphite, and fiberglass were conducted. A TIM tester was utilized to measure the specific thermal resistances across the different...
ldquoDevelopment for advanced thermoelectric conversion systemsrdquo supported by the new energy and industrial technology development organization (NEDO) has been successfully completed as one of the Japanese national energy conservation projects. Three types of the cascaded thermoelectric modules operating up to 850 K in high electrode temperature and two types of Bi-Te thermoelectric modules operating...
