半导体制冷片的选型和应用
半导体制冷片 （Thermoelectric Cooler) 的选型和应用的英文介绍。
半导体制冷片 广泛应用于 通讯；医疗；激光 等行业。
A typical single stage cooler consists of two ceramic plates with p- and n-type semiconductor material bismuth telluride) between the plates. The elements of semiconductor material are connected electrically in series and thermally in parallel. When a positive DC voltage is applied to the n-type thermoelement, electrons pass from the p- to the n-type thermoelement and the cold side temperature will decrease as heat is absorbed. The heat absorption (cooling) is proportional to the current and the number of thermoelectric couples. This heat is transferred to the hot side of the cooler, where it is dissipated into the heat sink and surrounding environment.
