- Description
- Abstract: A regenerator-based engine or refrigerator has a regenerator with two ends at two different temperatures, through which a gas oscillates at a first oscillating volumetric flow rate in the direction between the two ends and in which the pressure of the gas oscillates, and first and second heat exchangers, each of which is at one of the two different temperatures. A dead-end side branch into which the gas oscillates has compliance and is connected adjacent to one of the ends of the regenerator to form a second oscillating gas flow rate additive with the first oscillating volumetric flow rate, the compliance having a volume effective to provide a selected total oscillating gas volumetric flow rate through the first heat exchanger. This configuration enables the first heat exchanger to be configured and located to better enhance the performance of the heat exchanger rather than being confined to the location and configuration of the regenerator. Market Applications: The present invention may be used in thermoacoustic engines and refrigerators including Stirling engines and refrigerators as well as pulse-tube refrigerators and hybrids thereof. Benefits: This technology overcomes the geometrical constraints that make it difficult to build heat exchangers cheaply; geometrical constraints also make it difficult to achieve excellent heat transfer in heat exchangers in regenerator-based engines and refrigerators. This technology overcomes those challenges by providing for greater surface area for heat exchangers, higher heat-transfer coefficients, and more structural design options. Intellectual Property Status: U.S. Patent Number 6,560,970 issued on May 13, 2003 on this technology. The University is seeking to license this technology for development and commercialization. Respondents interested in obtaining such a license are asked to send letters of interest to the attention of Kathleen Herrera at the address below. The University will accept such letters until October 6, 2003. Those respondents will then be asked to prepare a commercialization plan explaining how that company envisions commercializing the technology. The University will select a potential licensee based on the content of the commercialization plans submitted by the respondents and proceed from that point into license negotiations for rights in the technology.
