设计制作了珀尔帖效应与塞贝克效应综合演示仪。采用 DS18B20温度传感器和WH7016M温度控制器控制制冷温度，利用LabVIEW软件在电脑上显示制冷温度变化曲线。通过电压表电流表显示温差半导体制冷和发电时的电压电流。该演示仪既克服了以往此类演示仪不能定量演示且只能演示一种效应的缺点，又实现了温度变化用计算机图形演示的功能。该仪器操作简单、性能稳定、效果明显，在课堂演示中取得了良好的效果。

A Peltier and Seebeck effects integrated demonstrator Design, which overcomes theflaws of traditional demonstrator only demonstrating an effect. DS18B20 temperature sensor and WH7016M temperature controller are used to control the cooling temperature,displaying cooling temperature on the computer by Lab-VIEW software. The voltmeter and ammeter show the voltage and current when TEC cooling and power genera-tion. It overcomes the weakness of other demonstrators not quantitative demonstration and only showing one effect. It also realizes the function of temperature change displayed by computer graphics. This instrument is a simple,stable performance,which achieves good results in the classroom demonstration.
