Cooling garment can provide cooling protection for all kinds of workers under high temperature and improve the comfort degree of human microclimate zone. This paper analyzes the cooling method, principles and characteristics of different types of garment, and summarizes the current research progress of the state of the art cooling garment. Moreover, key technologies and research directions of phase change cooling garment are described. Also discussed are issues such as liquid phase change material against leakage and erosion, easy plastic packaging materials and good packaging technology, improved thermal conductivity of phase change material, combining nano technology with phase change material microcapsule for long-life and good heat dissipation composite phase change material, and combining phase change cooling technology with other technologies for cooling effect controllable garment. New equipment or new material which can quickly activate the phase change material is proposed as well so that the phase change material can quickly store cold and reduce the heat of human body.
