| Summary: | 碩士 === 國立臺北科技大學 === 能源與冷凍空調工程系碩士班 === 98 === Closed type server cabinets are supplied with cool air so that the servers can draw cool air for maintaining proper heat rejection. As the result of intensive energy consumption, IDC has consumed more power than television sets in the United States. In future cloud computing would only cause IDC to become a major energy use in developed nations. This study investigated the horizontal blade servers and rack servers closed when the heat applied to comparative performance, and to computational fluid dynamics software (FLUENT) to establish closed cabinet of 3D model to numerical simulation of flow field and temperature cabinet. The parameters studied were: (1) cabinet air entrance holes, (2) variable air volume of the cabinet, (3) The return flow of heat. Change the air flow through the entrance hole in the cabinet, when the cabinet air flow entrance and the entrance ipsilateral server, the server will result in the decline of the air temperature rise and exports. Changing the variable air volume of the cabinet, the cabinet out to improve air flow would reduce the amount of servers and increase the primary air fan energy. It was found to enhance the fan cabinet fan noise caused by wind along larger. Blade closed cabinet design, the server can be compared to horizontal to accommodate more servers, rack heat load when the blade reached 3.334kW, its blade server rack the average exit temperature of 307.7K (34.7 ℃), 2kW heat load at the time, its blade server exit temperature is 304.9K (31.9 ℃), the average temperature rose by only 2.8K, can be seen blade servers in the parameter optimization, additional heat inside the cabinet load, and heat dissipation without sacrificing server performance.
