[0026] Through the above structural design, the tested product and data acquisition equipment are separated in two environments, which not only meets the aging temperature of the tested product of 85±5℃, but also meets the optimal working temperature of the instruments and meters in the data acquisition equipment of 27±5℃. At the same time, there is no need to arrange a small room in the high temperature room to place the instruments and meters, which reduces the space occupied by the high temperature room. Compared with the aging cabinets currently used in the past, the volume is reduced and the energy consumption is reduced.
[0027] The aging cabinet in this embodiment is as follows Figure 2As shown, the aging cabinet 1 includes a cabinet body and a high-temperature cabinet control box 11 arranged on the cabinet body, and a controller and a power supply unit are arranged in the high-temperature cabinet control box 11.
