Gelişmekte olan laminer akışta mini kanallı soğutucu bloğun çok yanıtlı taguchı yöntemi kullanılarak optimizasyonu

Abstract

Excessive heat dissipation which adversely affects the working performance of electronic equipment is an important technological problem due to developing technology, increasing power and reducing dimensions. In this context, researches on the liquid-cooled mini-channel blocks are increasing. While it is expected that the cooling blocks is desired to have high heat transfer performance with a minimum pressure drop in terms of operating costs. This requires optimization of the geometric structure in the design of the cooling block. In this study, the design of a mini channel water cooled block to be used for the cooling of a chip, has been optimized with three different materials for high heat transfer performance and low pressure losses. The performance of the mini-channel cooling block, which is designed with different materials and different channel dimensions by utilizing the Taguchi orthogonal matrix, was investigated by using Computational Fluid Dynamics (CFD). As a criterion, the pressure loss and the maximum temperature at the base were taken into consideration. Since both criteria were taken into consideration, Multi Response Taguchi Analysis was used in the optimization. Temperature and pressure loss values were evaluated and optimized by the use of different weight values.
