  • 결정성장 도중 전류에 의해 고/액 계면에서 발생하는 Peltier 열을 이용하면 온도구배의 증가와 이에 따른 성장속도의 증가 및 결정성의 향상에 기여할 것이라 예상되어, 고/액 계면에서 복합적으로 발생하는 Peltier 효과를 조사하였다. 전류 밀도, 극성 및 온도구배의 변화에 따른 고상과 액상 및 그 계면에서의 온도변화로부터 이론적 추론에 의해 Peltier 열, Thomson 열 및 Joule 열만의 영향으로 분류할 수 있었고, 고상/액상 계에 대한 Peltier 계수 및 Thomson 계수도 구할 수 있었다.

  • This paper presents temperature control of aluminum plate using Peltier module. As one of the thermoelectric effect, Peltier effect is heat pumping phenomena by electric energy. So if current is charged to Peltier module, it absorbs heat from low temperature side and emits heat to high temperature side. In this experiment, Peltier module is used to control the temperature of small aluminum plate with heating and cooling ability of Peltier module with current control and fan On/OFF control. And current control of Peltier module was accomplished by PWM method. As a results of experiments, it takes about 125sec to control temperature of aluminium plate between $30^{\circ}C\;and\;70^{\circ}C$ and about 70sec between $40^{\circ}C\;and\;60^{\circ}C$, in ambient temperature $29^{\circ}C$ while operating cooling fan only while cooling duration. Future aim is to realize more rapid temperature control and develop SMHA(special metal hydride actuator) by using Peltier module as a heating and cooling source.

  • This study is experimentally performed for using the oyster shell as a desiccant in the batch type system. The peltier element(thermoelectric device) is used for absorbing and releasing the adsorption and desorption heat generation. The cooling and heating effects of peltier element exist in this experiment and these effects are generally known phenomena among some references. The increase in electric current induced into peltier element is effectively release the heat generation of adsorption and desorption. Consequently, the non-dimensional adsorption and desorption amount would increase with increase in electric current. However, in the case of adsorption, the increase of induced current into peltier element, the heat of cold side can not release sufficiently. So the heat of hot side of peltier is transferred into the cold side.

  • This paper presents the temperature control in aluminum plate with Peltier module. From the experimental work, Peltier module is used to control the temperature of small aluminum plate for both heating and cooling with the control of current and fan ON/OFF. And current control of Peltier module was accomplished by PWM method. As a result of experiments, it is proper that operate cooling fan only while cooling duration and there exist a proper cooling current to drop temperature rapidly. It takes about 125sec to control temperature of aluminium plate between $30^{\circ}C$ and $70^{\circ}C$ and about 70sec between $40^{\circ}C$ and $60^{\circ}C$, in ambient temperature $28^{\circ}C{\sim}29^{\circ}C$ while cooling fan is operated only cooling duration. With the cooling current, temperature control of aluminum plate was accomplished more rapidly in comparison without cooling current. Future aim is to realize more rapid temperature control and develop SMHA(special metal hydride actuator) by using Peltier module as a heating and cooling source.

  • This paper presents the temperature control of aluminum plate by using Peltier element. Peltier effect is heat pumping phenomena by electric energy as one of the thermoelectric effect. So if current is charged to Peltier element, it absorbs heat from low temperature side and emits heat to high temperature side. In this experiment, Peltier element is used to control the temperature of small aluminum plate with current control and operating cooling fan only while cooling duration. Operating cooling fan only while cooling duration is proper to get more rapid heating and cooling duration. As a result of experiment, it takes about 100sec period to repeating temperature between $35^{\circ}C$ and $70^{\circ}C$ and about 80sec from $40^{\circ}C$ to $70^{\circ}C$ in ambient air temperature $25^{\circ}C$ and while operating cooling fan only in cooling duration. Future aim is to apply this temperature control method in actuating SMHA(special metal hydride actuator) which is applicable in Siver project acting in low frequency range by using Peltier element for heating and cooling.

  • $\textrm{Bi}_{2}\textrm{Te}_{3}$의 고/액 계면을 통하여 전류밀도와 방향을 달리 하면서 통전시켰을 때 발생하는 고상, 액상 및 고/액 계면에서의 미소 온도변화를 측정하였다. 이 냉각(가열) 효과는 전류밀도, 통전방향 및 시간에 따라 다르게 나타났으며, 온도변화에 미치는 Peltier 열, Thomson 열 및 Joule 열의 영향을 이론 및 실험에 의해 각각 분류하였다. $\textrm{Bi}_{2}\textrm{Te}_{3}$의 고/액상간의 Peltier 계수는 -1.10$\times\textrm{10}^{-1}$V이었으며, 고상과 액상의 Thomson 계수는 각각 7.31\times\textrm{10}^{-4}V/K와 5.77\times\textrm{10}^{-5}V/K이었다. 직류를 통전하면서 Bi$_2$Te$_3$결정을 성장한 결과, 고상에서 액상으로 통전한 경우, Peltier 냉각에 의한 온도구배의 상승으로 방향성이 향상된 결정을 얻을 수 있었지만, 전류의 방향을 반대로 하면, 결정성 향상에 별 도움을 주지 못하였다.

  • In the research, we developed a device for cooling the drive section of the gripper of a robot for handling the high temperature material. In this study, By using a Peltier element, the high-temperature material is not affected and driving cylinder is cooled to prevent damage due to high temperatures. Hot part of the Peltier element is towards the robot gripper. Cool part of the Peltier element is towards the driving cylinder. The heat sink portion is made to keep the cooling effect. As the performance result, cooling-test is taken, and their result is satisfy.
