To realize the down sizing of the loop tube cooling system, two experimental discussions are performed. First, the heat pump position is discussed. Cooling characteristic is measured when the heat pump position is changed in the down sizing of loop tube. From the experimental results, the phase difference of sound pressure and particle velocity is important to improve the cooling characteristic. Second, the parameter ωτ is discussed. This parameter is regarded as the dimensionless quantity to express the efficiency of heat-exchange ratio of the system. The experiments are carried out by changing the total length of the loop tube under the same constant value of ωτ. From the experimental results, ωτ is the useful and important parameter for the design of the miniaturization of the loop tube cooling system.
