자연대류와 강제대류에서 펠티에 소자를 이용한 내부터널 구조를 가지는 히트싱크에 관한 연구

국문 초록 (Abstract)

펠티에 소자는 전자부품이나 장비에서 발생하는 열을 냉각하기 위한 방법으로 많이 사용되고, 히트싱크는 이러한 열을 외부로 방출하기 위한 방법으로 많이 사용되고 있다. 본 연구에서는 내부터널의 형상을 가지는 히트싱크에 대한 냉각 및 히팅성능을 자연대류와 강제대류 상태에서 열전달 특성에 대하여 고찰하였다. 또한, 시간에 따른 히트싱크의 열전달 특성 및 온도분포의 변화에 따른 실험을 수행하였고, 자연대류와 강제대류에 따른 히트싱크의 열전달 특성, 온도분포의 변화를 실험을 통해 비교 연구 하였다. 냉각 실험에서 A형상 및 B형상 냉각 핀 히트싱크는 자연대류보다는 강제대류에서 온도가 더 감소하는 것을 알 수가 있었고, 강제대류와 자연대류에서 A, B형상 모두 -15℃까지 떨어지는 것을 알 수 있었다. 전압이 증가 할수록 강제대류와 자연대류 상태에서 A, B형상 냉각 핀 히트싱크 모두 온도가 감소하였다. 히팅실험에서 A형상 및 B형상 냉각 핀 히트싱크는 자연대류보다는 강제대류에서 온도가 더 증가하는 것을 알 수가 있었고, 강제대류와 자연대류에 서 전압이 13V일 때, A형상 냉각 핀 히트싱크는 전압이 150℃, 강제대류에서 B형상 냉각 핀 히트싱크는 145℃까지 증가 하였다. 전압이 증가할수록 강제대류와 자연대류 상태에서 A, B형상 냉각 핀 히트싱크 모두 온도가 증가하였다.

The Peltier Module has been used to dissipate the heat from electronic devices and electronic components. In this module, a heat sink is used to release the operating heat into the air outside. This study addressed the heat transfer characteristics for a heat sink with an inner tunnel. Under forced and natural convection conditions, the heat transfer characteristics were different. Therefore, the cooling and heating performances were studied for the heat sink, which has an inner tunnel. The heat transfer conditions were also evaluated by performing an experimental test, which investigated the heat transfer characteristics related to the variance in time and temperature distribution. Experiments on the heat transfer characteristics of the heat sink were conducted based on the forced and natural convection and temperature distribution changes. In the cooling experiment, the A- and B-shaped cooling pin heat sinks decreased the temperature of the forced convection than the temperature of natural convection. In the forced and natural convection, the A- and B-shaped decreased to a minimum of -15°C. Under the forced and natural convection conditions, A- and B-shaped cooling pin heat sinks decreased the temperature when the voltage was increased. In the heating experiment, the A- and B-shaped cooling pin heat sinks increased the temperature of the forced convection than the temperature of natural convection. In forced convection, when the voltage was 15°C, the temperature of the A-shaped cooling pin heat sink increased to 150℃, and the temperature of the B-shaped cooling pin heat sink increased to 145℃. Under forced and natural convection conditions, the A- and B-shaped cooling pin heat sinks showed an increase in temperature with increasing voltage.
