We describe an apparatus and a method that directly measure the cooling performance of a TEM such as current for maximum cooling (I-max), maximum cooling power (Q(c,max)), and maximum temperature difference (Delta T-max). The apparatus is designed based on a finite element model to ensure a simple heat flow measurement. We evaluate the module performance metrics based on differential measurement between the cooling powers with temperature difference across the module under transient conditions. The use of transient data reduces measurement time, and the use of a differential technique enables compensation of the thermal losses. The measured data fit well with conventional theoretical relations for the TEM performance metrics. We test a commercial TEM and validate the results using the Harman method. (C) 2015 Elsevier Ltd.
