Analysis and optimization of electroformed dendritic structures as enhanced heat transfer surfaces
(University of Missouri--Columbia, 2009)Over the past several years, the use of passive cooling devices in electronics such as heat pipes and vapor chambers has increased. Due to their more widespread use, these technologies have a high demand for more adaptable ... -
Compact oscillating heat pipe and development of fuzzy copper or wicking structures
(University of Missouri--Columbia, 2008)A central processing units (CPU) calculation speed is limited by the heat it produces. As the number of transistors and the clock speed of CPUs increase they become more powerful, but they also generate more heat which ... -
An experimental investigation of a meter-scale flat-plate oscillating heat pipe
(University of Missouri--Columbia, 2016)Ever-increasing demand for power in modern electronics presents challenge in thermal management. This paper shows the oscillating heat pipe (OHP) is considered a preferred solution for high heat application due to its heat ... -
Experimental investigation of a novel disc oscillating heat pipe and heat conduction effect on the startup of oscillating motion

(University of Missouri--Columbia, 2013)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] With ever increasing technological advances in electronics, modern computer components continue to produce higher power densities that present a challenge ... -
Heat and mass transfer of ambient air flowing over cold fins
(University of Missouri--Columbia, 2016)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Moisture condensation takes place as ambient air is contacting a surface with a temperature lower than the dew point. In the current investigation, a ... -
Heat transfer analysis in a finned heat sink embedded with two-phase heat pipes
(University of Missouri--Columbia, 2016)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The semiconductor technology development, as fast as consumer demands, led to advancements in miniaturization and power of computer chips. The low ... -
A high efficiency ejector refrigeration system
(University of Missouri--Columbia, 2010)In a time when efforts to reduce high-grade energy consumption are a necessity, it is useful to develop innovative alternatives to technologies that involve large amounts of power consumption, such as vapor compression ... -
An investigation into thermoelectric coolers
(University of Missouri--Columbia, 2018)A thermoelectric cooler (TEC) is a type of cooler that uses the electricity between the junction of two materials to cause a temperature drop. These coolers operate using the Peltier effect. Effectively, a TEC uses electrical ... -
Investigation of a flat plate oscillating heat pipe as a thermal spreader with centered heating
(University of Missouri--Columbia, 2015)Flat plate oscillating heat pipes are a relatively new and developing technology. They show much promise for advanced thermal management of current and future electronics cooling. However, while making them is easy, modeling ... -
Theoretical and experimental investigation of oscillating heat pipes
(University of Missouri--Columbia, 2006)A mathematical model describing the oscillation characteristics of slug flow in a capillary tube is presented. The model considers the vapor bubble as the gas spring for the oscillating motions in a capillary tube including ... -
