基于冬季人们对保暖产品的巨大需求，以及市场现有产品起热慢，温度不可控等缺点，本文开发了一种基于珀尔贴效应的新型柔性复合热电发热贴片，并对该发热贴片进行了性能测试。结果表明：发热贴片的塞贝克系数为92μV∕K，导热系数为0.224 W/(m?K)，平均电阻值为38.58Ω。当发热贴片置于皮肤上施加0.3 A电流时，热端最高温度可达45.5℃；置于衣物上施加0.4 A电流时热端最高温度可达56.3℃。与传统暖宝宝相比，该发热贴片升温至最高温度的时间大幅缩短，恒温使用时长大幅增加，可以反复使用。
Abstract：Based on the great demand of heating products in winter and the disadvantages of the existing products in the market, such as slow heating and uncontrollable temperature, a new flexible composite thermoelectric heating patch based on Peltier effect is developed in this paper and the performance of the heating patch is tested. The results show that the Seebeck coefficient, thermal conductivity coefficient and average resistance are 92 μV/K, 0.224 W/(m?K), 38.58 Ω respectively. The highest temperature at the hot end can reach 45.5 ℃ when a current of 0.3 A is applied to skin and 56.3 ℃ when a current of 0.4 A is applied to clothing. Compared with the traditional warmer patch, the time for heating the heating patch to reach the highest temperature is significantly shortened and the duration of constant temperature use is also increased by a large margin. Additionally, it can be used repeatedly.
