The principle of the medical vaccine storage and transportation device based on the multilayer phase change cold storage gel structure provided by the embodiment of the invention is as follows:
the optimal medical vaccine storage and transportation device structure based on the refrigeration film takes the phase change energy storage material of water as a refrigerant, and utilizes phase change conversion to release cold, wherein the hydrogel is a gel taking water as a dispersion medium and is a high-molecular network system, the high-molecular network can change the water state and water vaporization behavior in the hydrogel, so that the energy required by water evaporation is further reduced, free water, intermediate water and bound water exist in the hydrogel, and compared with the free water, the intermediate water has less energy requirement on water evaporation, so that the water evaporation and heat absorption in the hydrogel are feasible, and the heat energy is used for the evaporation of the water in the molecular network by introducing external heat into the hydrogel; the function of the aerogel is mainly embodied in three aspects, firstly, the aerogel is a nano-scale porous solid material, has high specific surface area and high pore volume rate, wherein the proportion of air is as high as more than 80 percent, so that excessive steam transmission resistance can not be generated for the evaporation of the inner-layer hydrogel, and when the external environment temperature is lower than the temperature in a box, the hydrogel film can absorb a certain amount of water vapor from the air to recover the self state; secondly, the aerogel and the hydrogel have a similar network system, so that evaporation and heat exchange of water in the hydrogel are facilitated; most importantly, the aerogel has good mechanical strength and physical properties, can bear pressure which is thousands of times of the self-quality, ensures the normal work of the hydrogel and the stable structure of the device, can be melted when the temperature reaches 1200 ℃, has excellent insulating property and can ensure the adaptability of the device; according to the experimental setting, hydrogel with the thickness of 5mm is laid in the device, the device is placed in a room environment at normal temperature, and the time of losing the refrigeration effect of the device is about 200 hours through tests, namely the time of single use of the hydrogel is as long as 200 hours; the porous heat collecting material can realize the absorption of the box body to the heat of the surrounding environment in the process of carrying in the open air, the energy is transferred to the hydrogel to compensate the energy loss of hydrogel evaporation, and the proper water transmission is ensured to realize continuous water evaporation.
The invention has novel structure and excellent comprehensive performance, and the device is found not to occupy too much space by simulating the actual storage and transportation environment, and the taking and using cannot be greatly influenced by keeping a space between teeth within a certain range by paying attention to the storage position structure. Experiments show that when a weight of 20kg is placed in the box body, the stacking height of the box body can reach three layers, and the basic life and transportation requirements can be met; the zigzag structure ensures that the device is stable and practical, and provides assistance for the uniform and proper temperature in the device; a porous heat collecting layer is additionally arranged between the aerogel-hydrogel film and the inner layer structure, the heat collecting layer can collect heat, the evaporation effect is enhanced, the pores are favorable for storing hydrogel to play a role, and the service life of the outer hydrogel and the refrigeration life of the device are prolonged.

And the standard calculation that 2.62 tons of carbon dioxide, 8.5kg of sulfur dioxide and 7.4kg of nitrogen oxide can be generated by burning one ton of coal is equivalent to the reduction of 2.92299 tons of carbon dioxide emission, the reduction of 9.48299kg of sulfur dioxide emission and the reduction of 8.25578kg of nitrogen oxide emission, so that the method has considerable energy-saving and emission-reducing benefits.
