Abstract:
Long-term work in the environment of high temperature and high humidity underground not only endangers the health of miners, but also easily leads to the occurrence of underground accidents. In view of this situation, personal cooling garments can be used as an individual cooling device. This paper summarizes the existing cooling garments technology and its development, which is divided into air-cooled garments, liquid-cooled garments, phase change garments, semiconductor cooling garments and chemical ice bag cooling garments according to the different cooling medium. This paper discusses the working principle, advantages and disadvantages, as well as the feasibility of existing personal cooling garments in the underground. Finally, this paper looks forward to the future development direction of personal cooling garments.
