Cooling treatment is known as one of the effective treatment for injury. It has an optimum cooling temperature level depending on a symptom or an injury. Hence a highly precise temperature control function is required for a cooling device for this kind of treatment. A mathematical model of cooling device using a Peltier element is necessary to realize its functions. In this paper, we examined the characteristics of model parameters by identification experimentally and comparison of its values. Three cooling devices (A, B and C) were used. A Peltier element of device A and device B were the same size with different cooling performance respectively. Whereas a Peltier element of device C was bigger than the two devices. Effects of devices size and cooling performance on the model parameters were investigated. It is shown that most of the parameter values were increased in the device C. The Seebeck coefficient and the internal resistance had little dependent relation with the device size while the other heat conductances were strongly dependence upon the size. From these results, the characteristics of each parameters became mostly evident by comparison of three devices of different sizes and cooling performances. However, it is required to analyze more and utilize different devices to carry out the development of cooling device by using this model.
