PURPOSE: A device for inspecting the performance of electric and machinery parts is provided to apply mechanical vibration with thermal impact to the electric and machinery parts while controlling humidity inside a chamber, thereby testing the performance of the parts under various conditions. CONSTITUTION: A device for inspecting the performance of electric and machinery parts comprises a first chamber, a second chamber, a humidity controlling unit(20), a liquefied gas supplying unit(10), and a heater unit. The first chamber includes a vibration plate where an external device is positioned. The second chamber includes a driving unit vibrating the vibration plate. The humidity controlling unit is connected to one side of the first chamber, thereby controlling the humidity by supplying steam to the first chamber or removing the steam existed inside the first chamber. The liquefied gas supplying unit decreases the temperature of the first chamber by supplying the liquefied gas to the inside of the first chamber, thereby applying thermal impact to the external device. The heater unit increases the temperature of the first chamber. |
