123温差电致冷器件在大气中的测试方法

Method for testing 123 thermoelectric cooling device in atmosphere

123(产品代号)温差电致冷器件是为便携式空调而设计的一种温差电致冷器件。根据温差电致冷器的实际应用情况,依据热平衡原理,设计出特殊的测试器件温差、致冷功率的方法。对实测值与理论值的差距进行了多方面的分析比较,同时也从实际的测试结果分析中确定了该器件的最佳工作电压范围为30～36V。

The 123 thermoelectric cooling device is designed for portable airconditioner. A special method to test the temperature difference and cooling power of the termoelectric cooling device was developed according to its practical operating conditions and the principle of heat balance. The deviation between the measured value and the theoretical value was analyzed and compared. The optimal operating voltage range of the device is determined to be within 30-36 V by means of the analysis of practical test result.
