Visual experiment device for frosting of trace water

The invention relates to a visual experiment device for frosting of trace water, and belongs to the technical field of design of frosting experiment devices. The device includes: a desublimation cavity which is internally provided with a desublimation cold surface for desublimation deposition of trace water vapor and growth of a frost layer; a cold source which is used for providing cold energy for desublimation and frosting of trace water vapor; a temperature control assembly which is used for controlling the temperature of the desublimation cold surface, so that the whole desublimation frosting process occurs under a constant-temperature condition; a micro-mass measurement assembly which is arranged at the bottom of the desublimation cold surface and is used for measuring the mass of a desublimated and frosted frost layer on the cold surface; a microscopic shooting assembly which is used for obtaining frost layer growth morphologies at different times and measuring the thickness of a desublimated and froste
