A Study of Optical Engine System Design With Promoting Heat Transfer
The purpose of this study is focused on the design and improvement of fan noise and heat dissipation at LCD Panel of optical engine. The measured temperature was proceeded in the laboratory of CHUANG YEOU technology company. The temperature results of numerical analysis were agreed with the present experimental measured temperature data. The numerical software of CFD code was employed to simulate and analyze the dissipative heat transfer in optical engine system. The Taguchi's method was also used to find the best dissipative heat transfer with improvement and design of an optical engine. The considered parameters of this study are airflows and rotational speed of four fans. According to the analysis of Taguchi's method, we had obtained that the best conditions of this optical engine system are A3(decreased airflow and rotational speed of suction fan),B1(increased airflow and rotational speed of discharge fan),C2(constant airflow and rotational speed of blower),D1(increased airflow and rotational speed of small fan). The present calculated results had analyzed an optimum condition by Taguchi's method, then we had found that the high temperature at B panel of LCD Panels (called R,G,B respectively) because the heat flow of an optical engine was brought to B by the rotated flow field was increased with the blowing upward airflow with rotation from blower. In order to improve the effects of rotating airflow, in this study we had presented the modified model(called P1) which is a punching hole under mirror. The calculated results of the modified model(P1) was shown that the thermal efficiency was better than the original model at 20.2%.
