Technical field
It is the cool-down garments of heat storage medium with the phase-change material that the utility model relates to a kind of, belongs to the articles for labour protection that use in a kind of high-temperature work environment.
Background technology
When the operation personnel wear the relatively poor protective clothes of high thermal resistance value and water-permeable and air permeable, or when working in the high-temperature operation environment, the quantity of heat production of human body is difficult to all shed, and can store in vivo.Body temperature will continue to rise in this case, and under the condition of non-infectious pathology heating, body temperature rises to 38.3 ℃ and causes light heat stroke, and when body temperature rose to 40.0 ℃, perspiration stopped, and severe heat stroke occurred, if do not take measures, the people will be in peril of one's life.
At present common solution is to increase cooling system on the protective garment basis, absorbs the human body quantity of heat production by cooling system, reduces human body accumulation of heat rate, make human body wear protective garment during not reason store too much heat and suffer heatstroke.The cooling system that is increased mainly contains three classes.The first kind is the pipeline cold supply system, and (Air Cooling AC) and liquid phase cools (LiquidCooling), owing to there being the cooling pipeline to link to each other with the operating personnel, cause personnel handicapped, and the auxiliary device volume is bigger, is restricted in the application to comprise gas phase cooling; Second class be evaporative cooling system (Evaporative Cooling, EC); The 3rd class is the phase-changing energy-storing cooling system, comprises ice bag cooling and the cooling of other phase-change materials, referring to " Zhang Fuli, the micro climate cooling system summary of heat-protective clothing. Chinese Individual protective gear, 2003,3:29~30 ".
Because phase-change material can be in a kind of narrow clear and definite temperature range, it is usually said interior its phase that changes of phase transformation range, form with latent heat absorbs, stores a large amount of heats, select the phase-change material of phase transition temperature near the body surface temperature, both can effectively absorb the unnecessary heat of human body, series of negative physiological reaction such as can not cause that again the excessive cold exposure of skin and vessel retraction, tissue are ached.
Existing use phase-change material has following defective as the cool-down garments of heat storage medium on the market.At first, the phase transition temperature of phase-change material is unreasonable, if the material phase transformation temperature is low excessively, will cause the too high series of negative physiological reaction such as cause that the excessive cold exposure of skin and vessel retraction, tissue are ached of heat flow; The too high then material of phase transition temperature is difficult to effective fusing, is not enough to offset the human body heat production, and cooling-down effect is not obvious.As use ice bag as coldness storage bag, low excessively user's the sense of discomfort that causes of the skin surface temperature of pressing close to it; Or the use fusing point is 29.92 ℃ six hydration calcium chloride (CaCl
26H
2O),, under intercepting, clothes can not effectively melt heat absorption, referring to " what is strong, cooling in summer clothes, CN 2229148Y, 1996.6.19 " because fusing point is too high less with skin surface temperature (33~34 ℃) difference.Secondly, phase-change material consumption and irrational distribution, the system of mourning of only will lowering the temperature becomes simple vest shape and be covered with coldness storage bag on vest, after body temperature upper zone phase-change material melts fully, other regional phase-change materials also do not melt, cause the waste on the overall consumption of phase-change material, make that also cooling clothes overall weight is excessive, influence user's normal activity; And there is excessive cold stimulation at the position that uniform phase-change material should not be suffered from cold to belly and waist, harm user's health.Thereby distribute and comfortableness is tested according to human body temperature, it is effectively and very necessary that phase transition temperature, consumption and the distribution on clothes of phase-change material is optimized.
The utility model content
