Cyclical-phase-transformation physical-temperature-control garment

Abstract

The invention relates to a cyclical-phase-transformation physical-temperature-control garment used for keeping the apparent temperature of a human body at comfortable temperature in hot summer and cold winter. The garment comprises an outer layer, a middle thermal-insulation layer and an inner layer, wherein the outer layer is used for reflecting most of infrared radiation in sunlight and part of visible light so as to reduce the absorption effect on external heat radiation; the middle thermal-insulation layer lowers heat transfer and heat convection and reduces heat exchanging to increase a temperature-control effect; in the microclimate within the thermal-insulation layer, the phase-transformation materials of the inner layer melt to absorb heat released by the human body; if the phase-transformation materials melt completely, the inner layer can be taken off and soaked in cold water for 1-2 minutes to allow the phase-transformation materials to be transformed from a liquid phase to a solid phase; in the winter, the cold water for soaking the inner layer is changed into hot water of about 45 DEG C; the phase-transformation materials of the inner layer include two different-melting-point phase-transformation materials respectively used for the winter and the summer.

Description

technical field [0001] The invention relates to the effect of physically controlling the temperature of the microclimate on the surface of the human body through the thermal properties of the phase change material, especially maintaining a stable and comfortable temperature for the human body in hot summer. Background technique [0002] There are various kinds of clothes in real life, and the types are various. Most of the functions of clothes are based on keeping warm, decorating and protecting the body. At present, the rapid development of social economy requires a large number of outdoor practitioners as a basis. In the hot summer, the temperature is often as high as 35°C or above. Construction workers, steel workers, and a large number of workers in high-temperature and sweltering environments need to endure extreme heat. In temperature to more comfortable clothes. The traditional mode of action of clothing determines that it cannot control the temperature within the c...

Similarly, in severe winters, especially those working in some extremely cold environments in northern regions, even if they wear thick clothes and the materials used in the clothes have good heat insulation effects, they cannot or can only achieve a warmer somatosensory environment. Someone has used the warm baby, which is based on the principle of using iron powder to oxidize and release chemical energy to generate heat slowly. This method is not repeatable, expensive, and a serious waste of resources.

At present, there are some cooling or heating clothes, which are complicated in structure and poor in effect, bulky, inconvenient to use, short in use time, not low-carbon and environmentally friendly, and high in manufacturing cost.
