Description

Cooling suit with phase-change material
Technical Field
The invention relates to the technical field of cooling clothes, in particular to a cooling clothes with phase-change materials.
Background
At present, most of the excavation depths of coal mines in China exceed 800 m. As the ground temperature increase rate of the coal field is generally 2-4 ℃/100m, the problem of high temperature of the mine becomes more and more prominent along with the continuous development of the mining depth of the mine to the deep part, and the thermal damage of the mine becomes a bottleneck for restricting the development of the coal industry. Therefore, the temperature of the mine is urgently reduced. When a worker wears the protective clothing with poor water and air permeability to work in a high-temperature working environment, the heat generated by the human body is difficult to be completely dissipated and can be stored in the body. In this case, the body temperature will rise continuously, and in the case of non-infectious pathological fever, the body temperature rises to 38 ℃ to cause mild heatstroke, and when the body temperature rises to 40 ℃, sweating stops, severe heatstroke occurs, and if no measures are taken, the person will be life-threatening.
At present, the common schemes for preventing and treating the heat damage of the mine mainly comprise a cooling system, a non-artificial refrigeration cooling technology and an artificial refrigeration cooling technology. The air quantity increasing is a non-artificial refrigeration cooling technology, and is a simple and feasible cooling method, but when the temperature of surrounding rocks reaches a certain height, the cooling range is limited, and the air quantity increasing cannot play a role in cooling due to the influence of factors such as the air inlet temperature and the temperature of the surrounding rocks. At the moment, a cooling system is needed to absorb the heat generated by the human body, the heat storage rate of the human body is reduced, and the protective clothing can achieve the effect of cooling. The incremental cooling system includes three types: the first type of pipeline cooling system comprises gas phase cooling and liquid phase cooling, and is inconvenient for personnel to move due to the connection of a cooling pipeline and operating personnel, and the accessory equipment has larger volume and is limited in application; the second type is evaporative cooling systems; the third type is a phase change energy storage cooling system. The defects of serious loss of cooling capacity of an air inlet roadway and large heat exchange capacity of a working surface exist in the aboveground refrigeration; the problems of heat accumulation due to heat condensation, unreasonable cold quantity transmission of a working surface and the like exist in the underground refrigeration mode; due to the damp-heat coupling, the high-temperature working surface has the problem of high humidity at the same time.
The development of cooling clothes has a certain breakthrough and progress so far, and can be roughly divided into three categories of gas, liquid and phase change. Gas and liquid cooling clothes have certain problems and are not widely applied at present.
