Abstract:
The research object is a micro heat exchanger (MHT) applied in chip cooling, a three dimensional simulation model is developed to analyze the transient heat transfer of the exchanger according to both exponential and periodic heat fluxes. Based on the computational results of the profiles of temperature and thermal stress, a comparison of performance of heat exchangers made of copper and silicon nitride compound is carried out. The results indicate that the capability of a copper heat exchanger is better than that of a silicon nitride exchanger under low load working condition due to the excel

Abstract:
A two-dimensional, transient mathematical model that accounts for diffusion and variable properties on the operation of a heat pipe is presented. The major advantage over previous models is that this model treats the noncondensable gas as a separate entity, which is described by mass transport phenomena. Also, the energy transport through the wall is coupled to the transient operation of the heat pipe through the use of a conjugate solution technique. The complete behavior of the heat pipe, along with the location and two-dimensional shape of the noncondensable gas front, are modeled from the

The transient response of an erodable ribbon element heat flux gauge has been assessed using a two-dimensional finite element (FE) analysis. Such transient heat flux gauges have previously been used for measurements in internal combustion (IC) engines. To identify the heat flux from the measurements of surface temperature, it is commonly assumed that the heat transfer within these devices is one-dimensional. A corollary of the one-dimensional treatment is that only one value of the thermal product, , is needed for identification of the transient heat flux, even though erodable heat flux gauges

In many research activities related to the heated environment near the wall or surface, measurement of transient surface temperature and determination of convective heating rate is one of the most important tasks.

Thin film gauges with these properties are best suited for such short duration transient surface temperature measurements. This study focuses on the establishment of

Under these conditions, it is reasonable to neglect the transverse temperature gradients in the casting and assume that all die temperatures below a certain depth from the cavity surface
