The Vuilleumier cryocooler is a heat engine which uses heat energy rather than mechanical energy to cyclically pressurize the working gas. The Vuilleumier cryocooler has the potential advantages of long lifetime and low mechanical vibration. This paper describes the specifications required for the machine, and detailes of design based an isothermal thermodynamic cycle. The analytical model can be used to clarity the working gas behavior in the system and determine the performance characteristics of the machine by calculating all losses to be mutually decoupled. As typical performance values from the calculation, the machine has a cooling capacity of 2.03 watts at 80 K under heater input power of 150 watts, charge pressure of 3 MPa and cycle speed of 4 s^<-1>. The nominal dimensions of the first trial machine are length of 300 mm, width of 150 mm and height of 280 mm. The weight of the complete machine was 6 kg.
