This paper presents an analytical model for on-chip heat dissipation in VLSI design. A chip and its test configuration also are developed to verify modeling results. The model and chip are representative of general IC packages. Our research shows that circuit location on a chip determines its default offset temperature and heat transport properties, which must be considered for accurate predict...

In this study, it was attempted to design a high-performance single-walled carbon nanotube (SWCNT) bundle interconnects in a full adder. For this purpose, the circuit performance was investigated using simulation in HSPICE software and considering the technology of 32-nm. Next, the effects of geometric parameters including the diameter of a nanotube, distance between nanotubes in a bundle, and ...

Thermal resistance is a key technical index which indicates the thermal management of multi-chip module high power LED (MCM-LED) packaging heat dissipation system. In this paper, the prototype structure of MCM-LED packaging heat dissipation system is proposed to study the reliable thermal resistance calculation method. In order to analyze the total thermal resistance of the MCM-LED packaging he...

Heat at the junction of light-emitting diodes (LED) affects the overall performance of the LED in terms of light output, spectrum, and life. Usually it is difficult to measure junction temperature of a LED directly. There are several techniques for estimating LED junction temperature. One-dimensional heat transfer analysis is one of the most popular methods for estimating the junction temperatu...

In this paper, we study the influence of heat sink (or source) on the peristaltic motion of pseudoplastic fluid in the presence of Hall current, where channel walls are non-conducting in nature. Flow analysis has been carried out under the approximations of a low Reynolds number and long wavelength. Coupled equations are solved using shooting method for numerical solution for the axial velocity...

Global warming induces a dramatic elevation of heat-related morbidity and mortality worldwide. Individual variation of heat stress vulnerability depends on various factors such as age, gender, living area and conditions, health status, and individual innate characteristics. Sasang typology is a unique form of Korean traditional medicine, which is based on the hypothesis that constitution-specif...

This paper presents the numerical analysis of a Miniature-Scale Refrigeration System (MSRS) for electronics cooling. The system consists of a simulated electronic chip attached to a microchannel cold plate evaporator, a compressor, a microchannel condenser, and an expansion device. The system uses R-134a as the refrigerant. A copper block heater is designed to simulate the heat generation of an...
