The Thermoelectric Module is a new type of artificial refrigeration technology development on the basis of the discovery in 1834 of Peltier effect. The use of Thermoelectric Module is used as a heat pump has the advantages of no pollution, small size, no noise and other characteristics in line with environmental protection requirements, low power consumption has been widely used in many industries. Thermoelectric Module production from material to product assembly process has certain reference now, but with the application of Thermoelectric Module is more and more widely than before, people's requirement on the efficiency of Thermoelectric Module and reliability becomes higher. people pay more deep research on the Thermoelectric Module. At present, the research for efficiency of Thermoelectric Module on the international is mainly concentrated in the material. However, the research of materials has certain limit, the research of materials had reached a bottleneck. NAUT (Non-contact Air coupled Ultrasonic Testing) is an inspection technique to remedy the existing contact inspection by supplementing energy loss created by differences of acoustic impedance between the solid and the air with high power ultrasonic Pulser Receiver, PRE-AMP, and high sensitivity probe, and enabling the ultrasonic inspection which uses the air as a medium. As explained above, in this thesis will show you how to use the NAUT to check out the defects inside. According to the scanning picture to judge the position and the size of defects inside. Above all, solved the problem of the detection of joint situation, and this method could give some help to improve the performance of Thermoelectric Module.
