According to the internet Trend Report of 2019, 51% of the world’s population can access the Internet. The network applications will become the mainstream of human activities, especially after the popularity of 5G in the future. In this study, the most important and classical DMAIC management model in six sigma management is used to improve and validate the fan wall quality of network rack servers according to the projects. This study found that simplification, energy and cooling efficiency are the main issues to be raised after defining the main products, and further in-depth measurement scheme is established. Then this study carries out FMEA analysis of the main projects, such as cooling fans, and finally carries out a case study to explore the fan wall quality of network rack server.

The mechanical integrity of the process machine is one of the provisions of the High-Hazard Chemical Process Safety Management Act promulgated by the US federal government. This study gradually reviewed the integrity of each process machine and factory supply system to improve the safety level. The primary focus is to understand the critical equipment and its related hazard characteristics, this must be cut from the process machine, from the power supply system, monitoring system, gas or chemical supply systems, reactors etc. to understand their possibilities of high temperature, leakage poisoning, corrosion, fire, explosion, electric shock, coiling and other hazards, and finally obtain the results of risk assessment for management use in high-tech factory. However, this study explores the focus of the safety and mechanical integrity of the process equipment, from identifying the critical equipment and hazard characteristics applicable to the equipment integrity plan of the future machine to the well-written mechanical integrity insurance plan, which can be used in practice.

The program objective is to develop SOFCs, operating in the 500-700 degrees C range, based on Metal/Electrolyte square cell honeycomb formed by simultaneous powder extrusion of electrolyte and metal interconnects on alternate layers. The alloy interconnect is being formed as an oxide powder mixture which will be reduced to the metal and then co-sintered with the electrolyte during hydrogen thermal treatment. Goals include power density of 5 KW/liter, alternative fuels, designed thermal management, and low fabrication cost. The project is divided into electrolyte/electrode development, fabrication of hybrid and electrolyte monoliths, and thermo-mechanical stress modeling and heat transfer. Honeycomb fuel cells offer a great potential for high-power density and low-cost manufacturing. Also, producing multiple layers simultaneously forms a gas-tight high temperature seal in a single step, minimizing or eliminating difficulties encountered in other designs (planar or tubular) of SOFCs. The unique honeycomb cell geometry, however, poses some challenges in application of electrodes with desired microstructures to the honeycomb channels. However, near the end of the program, success was obtained in reduction and co-sintering of crack free, hermetic SOFC platform with alternating layers of metal interconnect and YSZ electrolyte. The structures were electroded and operated as fuel cells at modest powder levels. In, monolithic, all YSZ, honeycomb fuel cells, power levels of 0.09 W/sq cm of electrolyte area, 0.30 W/cu cm of call volume, and 0.15 W/g was achieved in the program.
