Dynamic reliability test equipment for power device

The invention relates to the technical field of testing equipment, in particular to power device dynamic reliability testing equipment which comprises a machine shell, an electric appliance element used for testing the dynamic reliability of a power device is arranged in the machine shell, and a plurality of sets of cooling fans are arranged on the two sides of the electric appliance element respectively. A mounting cylinder is movably arranged below the electrical component, a mute fan is arranged in the mounting cylinder, a ventilation groove is formed in an opening in one end, close to the electrical component, of the mounting cylinder, and a filter screen is mounted on an opening in the other end of the mounting cylinder. High-temperature heat dissipation can be carried out on the left side, the right side and the lower side of the electric appliance element through multiple sets of heat dissipation fans and mute fans, and the heat dissipation effect is better; when the silent fan works, air outside the m
