Multi-stage temperature control protection design device for glasses based on phase change material and protection method thereof

Abstract

The invention discloses a multi-stage temperature control protection design device for glasses based on a phase change material and a protection method thereof. The device includes a glasses frame, aninsulating casing, a button cell, a longitudinal magnetic field generator, a transverse magnetic field generator, explosion-proof lenses, a phase change nano capsule, a temperature sensor, a carbon nano micro channel, a fiber foam framework and a phase change material layer. The device is advantaged in that the phase change nano capsule and the phase change material layer are utilized to emit orabsorb heat in the phase change process, low temperature damage and condensation corrosion of the lenses are avoided, and overheating damage to the lenses in the external high temperature environmentis further avoided; the characteristic that a heat conductivity coefficient of the fiber foam framework is inversely proportional to the temperature is utilized, and anti-freeze insulation of the lenses under the low temperature, steam condensation and overheating under the high temperature are further realized; the effect of enhancing heat transfer or suppressing heat transfer is achieved by mixing single-walled carbon nanotubes or graphene nanosheets in the carbon nano micro channel with magnetic nanoparticles, and the device has the multi-level protection function, is highly adaptable to the environment and can be used in the extreme environment where the temperature difference varies greatly.

Description

technical field [0001] The invention relates to the field of phase change heat storage and heat release, in particular to a multi-stage temperature control protection design device for glasses based on phase change materials and a protection method thereof. Background technique [0002] In real life, glasses are composed of lenses and frames. There are four kinds of glasses for myopia, glasses for farsightedness, glasses for presbyopia and glasses for astigmatism. With the development of the times, there are more and more wearers of glasses, and the use of glasses is becoming more and more popular. However, there are still many maintenance problems in glasses at this stage. It is necessary to avoid long-term direct sunlight and high temperature (above 60 °C), otherwise they will be easily damaged. Cause lens, frame deterioration, deterioration, discoloration, etc. In the future, the survival and development footprints of human society will spread all over the world, and ev...
