Nothing has really happened until it has been described.

Timothy J. Dake received his B.S. degree in Mechanical Engineering from Marquette University in December 2001. He then worked with Dr. Majdalani as a Research Assistant in the area of thermal management and electronics cooling.  He also served the Department of Mechanical Engineering as a Teaching Assistant, helping to organize and lead numerous Laboratory sections for the Energy Conversion Processes and Instrumentation and Measurements courses.  While his technical assistance to Dr. Majdalani led to several proposal grants and awards, his research work led to an important discovery in thermal management.  He determined that flow vortication in a confined space can have a significant effect on heat transfer enhancement; so he set on to research the most practical and simple configurations that could lead to flow-heat transfer enhancement in the context of electronics cooling. After experimenting with nearly a hundred different designs, he determined the optimal winglets/vortex trippers that generate the strongest vortices in channel flow. He also discovered that quadrupole vortices are among the simplest and most effective ways to control the flow in a channel.  His work led to a comprehensive 325-page M.S. thesis that was published in two volumes, in December 2004.  He graduated with a 3.875 GPA after receiving the 2002-2003 Graduate Fellowship Award from the NASA Wisconsin Space Grant Consortium for his work on "Cooling of the Next Generation Micro-Chips in Aerospace Communications."

Prior to beginning graduate degree work, he was employed for 15 years as a thermal engineer designing heat exchangers and HVAC&R systems (Modine/Thermacore). This professional work included projects involving the cooling by refrigerants and glycol solutions of servers and PCBs. During this period of full-time, professional employment, he has completed a Bachelor of Science degree in Mechanical Engineering with focus in thermal system analysis. While at Modine and Thermacore, he personally designed hundreds of heat exchangers of various types; participated in the design of nearly every kind of HVAC&R system; developed dozens of new products and methods of design and construction; tested and simulated scores of heat exchangers and systems; and was an integral part of the development of numerous new heat transfer advancements.

During his tenure in industry, he completed or took part in several major projects, including bringing the first HVAC&R application of a micro-channel all-aluminum heat exchanger to market in the Tecumseh Products AE-MAX condensing unit; leading development of a liquid cooling system for Sun servers; design and development of an all stainless steel, epoxy joined heat exchanger for a potable water distiller system for In-Sink-Erator; and more recently, design and development of large, stainless steel heat exchangers for power plant fuel cells for Ballard Systems and UTC. His MS project addressed an important case arising in multi-board chip package thermal management.
