Passive Thermal Management Using Phase Change Materials, Yash Yogesh Ganatra
Open Access Theses
The trend of enhanced functionality and reducing thickness of mobile devices has led to a rapid increase in power density and a potential thermal bottleneck since thermal limits of components remain unchanged. Active cooling mechanisms are not feasible due to size, weight and cost constraints. This work explores the feasibility of a passive cooling system based on Phase Change Materials (PCMs) for thermal management of mobile devices. PCMs stabilize temperatures due to the latent heat of phase change thus increasing the operating time of the device before threshold temperatures are exceeded. The primary contribution of this work is the identification …
Non-Invasive Measurement Of The Internal Temperature Of Heat-Generating Bodies, Dean Raymond Anthony
Non-Invasive Measurement Of The Internal Temperature Of Heat-Generating Bodies, Dean Raymond Anthony
Mechanical and Aerospace Engineering Theses
While the surface temperature of a heat-generating solid body can be measured using a variety of methods, there is a scarcity of techniques that exist for non-invasively measuring the temperature inside the solid body. Internal temperature measurement is very desirable as mere measurement of surface temperature gives no indication of the internal temperature. The highest temperature, usually located at the core of the body, dictates system performance and safety. For example, Li-ion cells provide good energy storage and conversion characteristics, but unfortunately suffer from safety problems related to overheating due to insufficient heat removal during operation. The following thesis presents …

Experimental Characterization Of Hybrid Cooled Cisco Servers Including The Effect Of Warm Water Cooling, Md Malekkul Islam
Mechanical and Aerospace Engineering Theses
The information technology (IT) owners are experiencing a greater cooling challenge because of the increase in power density due to modern computational needs. The non-uniform power density in each server is forcing the industry to use hybrid cooling technology. Server components of different cooling requirement needs air water hybrid cooling which offers variable design alternatives. Such hybrid cooling technology cools the high heat generating components by using water or water based fluid, whereas, the rest of the components are cooled by air using internal fans. Conventional air cooling is more than sufficient for the components with less thermal demand. Air …
