Energy Analysis of Novel Data Center Cooling Technology : Evaporative Cooling System Operation and Microchannel Heat Exchanger Manufacturing

Creator:: Lajevardi, Babak
Abstract:: Worldwide, many organizations are pursuing higher energy efficiency by reducing power consumption of their processes, systems, and supporting infrastructure. The rapid growth of the information technology (IT) industry and the miniaturization of semiconductors have resulted in substantial increases in energy consumption and power density of IT equipment, and, subsequently, heat...

A microchannel-based thermal management system for hydrogen storage adsorbent beds

Creator:: Steigleder, Leif J.
Abstract:: Hydrogen has been shown to be a promising replacement for fossil fuels for use in light duty vehicles because it is a clean, renewable and plentiful resource with a high gravimetric energy density. However, in order to obtain an acceptable volumetric energy density, densification of the hydrogen is required. Adsorptive...

Development of a radial microlamination architecture for cylindrical microchannel arrays

Creator:: Vlieg, James H.
Abstract:: Microchannel arrays are being developed across a wide spectrum of microfluidic applications including blood processing, fuel cells and thermal management among many others. Typical arrays are based on a flat laminated architecture produced in a vacuum hot press (VHP) through solid-state diffusion bonding. Due to the cylindrical nature of certain...

Laser keyhole welding for microlaminating a high-temperature microchannel array

Creator:: Lajevardi, Babak
Abstract:: Microchannel process technology (MPT) components are chemical unit operations which exploit highly-parallel arrays of microchannels to process large fluid volumes for portable and distributed applications. Microchannel heat exchangers (MCHXs) have demonstrated 3 to 5 times higher heat fluxes when compared to conventional heat exchangers resulting in proportionate reductions in size...

A Manufacturing Process Design for Producing a Membrane-based Energy Recovery Ventilator with High Aspect Ratio Support Ribs

Creator:: Kawula, Steven P.
Abstract:: Heating, ventilation, and air conditioning systems represent nearly half of building energy usage in the United States. Recent building regulations requiring increased air turnover within buildings will result in even greater air conditioning usage. To alleviate these concerns, membrane-based heat-and-moisture exchangers known as energy recovery ventilators have been developed to...

Determining the dimensional requirements of a reliable compression sealing method for use in microchannel hemodialysers

Creator:: Ward, Dustin K.
Abstract:: Almost 600,000 people in the United States were treated for End Stage Renal Disease in 2010. A majority of those people received hemodialysis from central medical facilities. It has been reported a better treatment option for these patients would be realized if the patients had more frequent hemodialysis treatments. A...

Manufacturing Process Design and Electrically-Assisted Embossing of a Microchannel Solar Receiver

Creator:: McNeff, Patrick S.
Abstract:: Manufacturing process design (MPD) represents a design-oriented approach to manufacturing engineering. In this dissertation, Haynes 230 (H230), a solid solution-strengthened Ni-based superalloy, was chosen to meet the material requirements of a microchannel solar receiver (MSR) needed to increase the efficiency and reduce the cost of solar thermal power generation. An...

Uniform residence time in microreactor-assisted solution deposition of CdS thin-films for CIGS photovoltaic cells

Creator:: Hires, Clayton Lamar
Abstract:: Photovoltaic (PV) cells have long been an attractive alternative for the consumption of fossil fuels but current manufacturing practices suffer from poor energy efficiency, large carbon footprints, low material utilization, high processing temperatures and high solvent usage. A critical step in PV production is the deposition of CdS as a...

Cooling rate limitations in the diffusion bonding of large microchannel arrays

Creator:: Lingam, Gopi K.
Abstract:: A significant barrier to the diffusion bonding of large (i.e. 600 mm) microchannel devices is the large capital investment required to setup production. This large capital investment extends from long heating and cooling cycles leading to poor production capacities. Empirical studies in industry have shown that cooling rate is limited...

Development of an economical high temperature microchannel recuperator for solid oxide fuel cells

Creator:: Brannon, Samuel T.
Abstract:: To improve the performance of solid oxide fuel cells, a secondary power cycle can be driven by the recuperation of exhaust gas heat. Microchannel recuperators are attractive for waste heat recuperation due to compact form factors which also minimize the mass of the expensive superalloys required. This paper introduces a...
