Abstract
We have been developing a small-size heat-driven pulse tube cooler to study the possibility of cold production. A thermal compressor unit of the Vuilleumier cooler was utilized for this machine. The charge pressure and speed of displacer piston were selected as major operating parameters. Test results of the heat-driven pulse tube cooler showed that the cooling temperature of 173 K without heat load, and 1 watt was maximum cooling capacity at 200 K.
