Patent number: 8763408Abstract: A hybrid thermoelectric-ejector active cooling system having an increased Coefficient of Performance (COP) when compared to typical thermoelectric cooling modules. A thermoelectric cooling module is integrated with an ejector cooling device so that heat from the thermoelectric cooling module is rejected to a high temperature evaporator of the ejector cooling device. This provides for a total COP greater than the sum of the COPs of the thermoelectric cooling module and ejector cooling device individually. For example, given 1 unit input power into the thermoelectric cooling module, the heat received by the cold side of the thermoelectric cooling module would be COPTEC×1; and the energy rejected by the hot side of the thermoelectric cooling module and to drive the ejector cooling device would be COPTEC+1. Thus, the cooling received by the low temperature evaporator of the ejector cooling device is COPEJ×(COPTEC+1); and therefore total COPTE-Ej-AC is COPEj+COPTEC+COPEj×COPTEC.Type: GrantFiled: October 1, 2010Date of Patent: July 1, 2014Assignee: The Curators of the University of MissouriInventors: Hongbin Ma, Peng Cheng, Joseph A.

Patent number: 8343280Abstract: A method and system for multi-zone control of temperature for a substrate is described. The temperature control system comprises a heat exchanger coupled to two or more fluid channels in a substrate holder configured to support the substrate. The heat exchanger is configured to adjust the temperature of a heat transfer fluid flowing through the two or more fluid channels. The temperature control system further comprises a heat transfer unit having an inlet that is configured to receive heat transfer fluid from the heat exchanger at a bulk fluid temperature. Additionally, the heat transfer unit comprises a first outlet configured to couple a portion of the heat transfer fluid at a first temperature less than the bulk temperature to a first fluid channel of the two or more fluid channels, and a second outlet configured to couple a remaining portion of the heat transfer fluid at a second temperature greater than the bulk fluid temperature to a second fluid channel of the two or more fluid channels.Type: GrantFiled: March 28, 2006Date of Patent: January 1, 2013Assignee: Tokyo Electron LimitedInventor: Shunichi Iimuro

Publication number: 20120305044Abstract: The invention relates to thermoelectric systems, devices and methods for generating energy and, providing cooling and heating. Non-ceramic thermoelectric technology is employed. In the invention, non-ceramic substrates are used to replace the ceramic layers which are typically utilized in conventional thermoelectric structures. The non-ceramic substrates can be selected from metals and metal-containing materials known in the art which have a surface modification, such as but not limited to, a coating or a surface restructuring. The incorporation of non-ceramic substrates allows several other components which are associated with the use of ceramic layers in conventional thermoelectric structures to be eliminated from the thermoelectric device.Type: ApplicationFiled: December 7, 2011Publication date: December 6, 2012Inventor: ANDREY A. ZYKIN
