Uniform-temperature high-temperature aging testing machine and high-temperature aging test method

Abstract

The invention relates to the technical field of aging testing, in particular to a uniform-temperature high-temperature aging testing machine and a high-temperature aging testing method. The uniform-temperature high-temperature aging testing machine comprises a heat insulation rack, an aging testing box, a heating device, a controller, a pressure release valve and a plurality of carrying tables, and a first constant-temperature cavity and a second constant-temperature cavity are formed in the heat insulation rack; the heating device is communicated with the first constant-temperature cavity and the second constant-temperature cavity, the multiple carrying tables divide the inner cavity of the aging test box into multiple aging test cavities, the aging test cavities are provided with temperature detection sets, the temperature detection sets comprise multiple temperature sensors, and the aging test cavities are provided with matrix valve sets; the aging test cavity is communicated with the first constant-temperature cavity and the second constant-temperature cavity through a matrix valve group; and the matrix valve group comprises a plurality of control valves or automatic opening and closing doors. The temperature of the inner cavity of the aging test box is rapidly increased, the high-temperature aging test can be carried out on a plurality of samples at a time, the high-temperature aging test efficiency of the samples is improved, the temperature is uniform, and the high-temperature aging test quality is high.

Description
