This paper presents an optimal design of a 1W / 80K co-axial miniature pulse tube cooler based on the aid of numerical model that incorporates both thermodynamics and hydrodynamics for the oscillating flow and the regenerator matrix. The simulation allowed clear visualization of the instantaneous parameters variations and the entire process occurring in the pulse tube cooler and gave quantitative information on the dominant influence in the cooling capacity of the co-axial miniature pulse tube cooler. The cooler should produce 1W of cooling power at 80K with a total input power of less than 30W and with a heat sink temperature of 300K. Based on the numerical analysis, a compact co-axial miniature pulse tube cooler with a rotary drive 1.66cc compressor was designed and studied. The flow channels of the pulse tube and regenerator were designed to fit the cold heat exchanger. A lowest temperature of 66.5K and cooling capacity of 0.6W at 80K with a total input power of 66W was achieved with the system pressure of 4.0MPa and the operating frequency of around 30Hz. This design was very compact and could be made into a commercially available pulse tube cooler.
