Thermal fatigue test device and thermal fatigue test method

The invention relates to the technical field of test equipment, in particular to a thermal fatigue test device and a thermal fatigue test method.The thermal fatigue test device comprises a containing component and a circulation part used for containing cooling liquid, the circulation part communicates with the containing component, and the circulation part drives the cooling liquid contained in the containing component to circularly move to a preset position. The temperature of the cooling liquid is within a preset liquid temperature range. According to the thermal fatigue test device and the thermal fatigue test method provided by the invention, the phenomenon that the temperature of the cooling liquid is increased due to the influence of the temperature of the sample is effectively avoided, the precision of the thermal fatigue test is improved, and the experimental error of the thermal fatigue test is reduced. 本申请涉及试验设备技术领域，尤其是涉及一种热疲劳试验装置及热疲劳试验方法，热疲劳试验装置包括容纳构件和循环部，用于容纳冷却液体，循环部与容纳构件连通，循环部驱动容纳构件容纳的冷却液体循环移动至预定
