Thermoelectric cooler ( TEC) is commonly used to cool and maintain laser diode module ( LDM) junction at predetermined temperature, therefore, the simulation for performance of TEC is very important for thermal design and optimization of LDM. 作为半导体激光器组件的重要一部分,热电制冷器(TEC)工作特性的模拟对激光器组件的设计与优化有着重要的意义。
For transforming compensating voltage to temperature, adopting least squares techniques to fit thermoelectric curves of thermo junction, the thermoelectric curve is acquired. 为了将补偿后的电压转换为测量点的温度值,本文采用最小二乘法对热电偶的热电特性曲线进行了拟合,得到了热电特性方程。
