  • The object of this paper is to propose a method to solve resulting heat in using numerous modulized watt-class LEDs in MCPCB as lighting device. To use LED for lighting, the chip needs to have a large capacity, resulting in extra heat in P-N connection area. To solve this problem, a Pottier Module, heat-sink panel and a fan was installed to measure variations in the temperature. Additionally, temperature variation characteristics were observed according to the heat conductor panel connecting cooling module and heat-sink panel, insulator and thermal grease. As a result, the type and amount of heat-sink panel was the most important facto. The fan would effect the temperature by max. $18[^{\circ}C]$ while other materials affected the temperature by $2{\sim}3[^{\circ}C]$, showing significant difference.

  • This study is to evaluate the cooling performance of the Bonding type and Injection type of heat sink using three different kinds of industrial Peltier module by digital $LabView^{TM}$ measurement. Injection type of heat sink could be more efficient for the heat transfer than Bonding type, even with 30% more radiating surface area. In addition, the experimental results revealed that the sufficient power supplied was able to show the better cooling performance of Peltier module.

  • 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.

  • The purpose of this study is to manufacture and test a thermoelectric generator which converts unused energy from close-at-hand sources, such as garbage incineration heat and industrial exhaust, to electricity. A manufacturing process and the properties of a thermoelectric generator are discussed before simulating the thermal stress and thermal properties of a thermoelectric module located between an aluminum tube and alumina plate. We can design the thermoelectric modules having the good properties of thermoelectric generation. Resistivity of thermoelectric module for thermoelectric generation consisting of 62 cells was 0.15-0.4$\Omega$ Developed thermoelectric modules can be expected th have better properties than thermoelectric cooling modules above $70^{\circ}C$ in temperature difference between hot and cold ends.

  • This article presents the optimal operation of an air conditioner using thermoelectric modules. A prototype of air conditioner using four thermoelectric modules has been designed and built. The system performance with evaporative cooling for hot side of the module are studied in detail for several operating parameters, such as input power to the thermoelectric module, fans and pump. It is found that the optimal input voltage to the thermoelectric module and pump is selected for the best system performance based on the cooling capacity and the COP at a given operating condition. It is also found that both the cooling capacity and COP of a system is increased with an increase in the input power to fans. The cooling performance could be improved when the ambient temperature is increased and the relative humidity is decreased since the evaporative cooling at the hot side has been increased.

  • 본 논문에서는 열전소자(TEC모듈)를 이용한 에어컨의 개발에 대하여 검토한다. 사용한 TEC모듈의 개수와 TEC모듈의 발열부를 냉각하는 FAN냉각방식과 분사냉각방식에 따른 냉각능력을 평가하였다. 분사냉각방식의 경우에는 기존의 에어컨과 동등한 수준의 냉각능력을 갖는다는 것을 알 수 있었다. 급속냉각은 어렵지만 약 1시간 후부터는 충분히 사용 가능하며, 열전소자 한 개당 약 1평을 냉각할 수 있으며, 기존에어컨의 가격에 비해 약 50∼70%정도로 충분한 가격 경쟁력이 있다. 빙축열 방식 등을 적용하면, peak 쳐t등의 효용성으로 상품화 가능성이 매우 크다고 판단된다.
