Description

Be used for performance server fin test mechanism Technical Field The invention relates to the technical field of cooling fin tests, in particular to a cooling fin test mechanism for a performance server. Background With the rapid development of the cloud computing and big data fields, the power density of a core device of a performance server is increased, a radiating fin is used as a core radiating component, and the integrity of welding seams between the fin and a substrate and between a heat pipe and the substrate directly determines the running stability of the server. If the weld joint has the defects of microcracks, cold joint and the like, the weld joint can be rapidly expanded in the running vibration environment of the server, and the loss is caused by the fault, so that the weld joint quality detection is a core quality control link. At present, nondestructive detection modes such as ultrasonic flaw detection and the like are mainly adopted in the industry to detect welding seams, but the existing test mechanisms are in a static detection mode and a cold and hot detection mode and are disjointed from the real service working condition of the radiating fin. When the performance server operates, the radiating fins are always in a continuous vibration state, and the alternating stress can induce the extension of hidden defects of welding seams, so that the hidden defects can not be detected by static detection, and serious hidden dangers of missed detection exist. In addition, the weld joint detection and cold and hot detection modes of the existing mechanism cannot be developed cooperatively, and the defect evolution process cannot be traced. Meanwhile, the server is miniaturized to be high in density, weld defects are tiny and hidden, and static detection is difficult to meet the high-precision requirement. In summary, aiming at the pain points such as the existing detection working condition disconnection, easy omission detection, poor synergy and the like, the development of a test mechanism capable of synchronously simulating the real vibration and the cold and hot environment of the cooling fin during the weld joint detection is urgently needed, the detection reliability is improved, and the high-precision detection requirement of the cooling fin of the performance server is met.
