Stack/Heat-Exchanger Research for Thermoacoustic Heat Engines.

摘要

The goal of this project was to develop novel configurations of heat pumping elements and heat exchangers for thermoacoustic heat engines. The approach involved the use of anisotropic systems employing innovative technology. The approach allowed a heat exchange fluid to flow directly across the heat pumping element of the thermoacoustic heat engine (the 'stack'), eliminating the necessity of separate heat exchangers and improving efficiency. The research has led to a radically new design, which is robust (using stainless steel and durable materials), relatively easy to fabricate, an employs a filament array or 'pin' stack. One patent has been awarded, and a second is in process. Several companies which can fabricate crucial components for future refrigerators were identified in the course of the research. The research formed the basis for a Ph.D. thesis.
