“…The heat released from the actuator is absorbed by the cold side of a thermoelectric cooler, and pumped to the hot side. The pumped heat with the input power to the cooler is then extricated to the ambient through a heat sink (Huang & Duang, 2000). , cooling load, which is conducted from the cold side to the hot side, should be greater than the heat generated by the coil for the proper cooling.…”

Large displacement, large generated stress and easy fabrication process lead to the large industrial use of the magnetostrictive materials. However, the thermal expansion restricts their application in precise positioning, which is about 12 ℃ ⁄ and too much to be neglected. In this research, the cooling system was exploited in order to eliminate the joule heat generated by coils under the direct current and solve inaccuracy problem. The investigation consists of two parts; first was design and fabricating the actuator of Terfenol-D with length of 30mm which offers 10 displacement under the DC current of 1A, and second was the cooling system consisting of the thermoelectric cooler, heat sink and control circuit to inhibit the Terfenol-D temperature to be increased. Without the cooling system, as the time was going on and the Terfenol-D was warming up, after about two hours the displacement reached to 68 which deteriorated the accuracy of positioning significantly. By applying the cooling system, the displacement was maintained in 10 with the tolerance of ±1 , which realized the precise positioning by the Terfenol-D actuator.

“…The next step in the proposed procedure is aimed to obtain the value of parameter , which is the parameter directly related to the thermoelectric effect. Knowing the value of it is possible to apply equation 2 also for T=0, hence The method to estimate these parameters based on Imax, Vmax, Qmax and Tmax [6] differ from these values 18,5% in the worst case. The main reason for a better accuracy of the method presented in this paper is the use of several data point read from the datasheet graphs instead of using just the values corresponding to the most extreme condition.…”

Manufacturers of commercial thermoelectric modules provide datasheets of the modules including information and graphs about the performance attained at several working conditions. Details about internal parameters are not made available to customers, because in the broad majority of the cases they are not necessary. However, when developing non-standard applications or conducting research projects it is sometimes necessary to make the modules work in different conditions than those shown in the performance curves. This paper shows a methodology to extract thermoelectric internal parameters from the information provided by performance curves, hence allowing scientists to predict the performance of the module at any working condition. The method is based on the basic equations that link thermal and electrical dynamics in which some parameters must be estimated. As a result it is possible to predict the behavior of the modules if they are operated in a non-standard way. One good example is to simulate how a module designed for cooling applications will behave if used as a Seebeck module for power generation. The proposed methodology has been successfully applied to a commercial Peltier module for which the behavior as a thermoelectric generator was simulated and then tested experimentally, attaining very similar results.

A thermoelectric module is a device, which can transfer heat from one surface to another surface when a current is applied. A cooling system employing the thermoelectric module is generally known as a thermoelectric cooling system. A thermoelectric cooling system has no moving parts and does not require any refrigerant, so they are environmentally friendly, inherently reliable, and virtually maintenance free. In this study, a numerical analysis for optimization of a thermoelectric cooler is presented. A single-stage system, cuboids type twostage system and pyramid type two-stage system are analyzed concerning maximum cooling capacity. For two-stage thermoelectric systems, which are composed of two thermoelectric modules, the optimum ratio of current for each stage is analyzed theoretically. The cooling load and heat sink design are also analyzed to optimize the cooling capacity. When the temperature of the hot side of the thermoelectric module was fixed for all systems, the pyramid type twostage system showed an approximately 10.48% higher cooling capacity than that of a single system. The method to improve the performance of the pyramid type two-stage system was suggested by reducing the wasted area of the module surface.
