Description
Technical field
The present invention relates to a kind of is the cool-down garments of heat storage medium with the phase-change material, 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 in 38.3 ℃ of light diseases of initiation and affixes one's name to, 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.
Summary of the invention
The purpose of this invention is to provide a kind of phase-change material cooling clothes, make its thermal comfort that can under hot environment, keep human body, and can user's health not damaged.
Technical scheme of the present invention is as follows:
A kind of phase-change material cooling clothes, it is characterized in that: described cooling clothes are made of vest, headgear and neck cover, chest and flank in described vest predecessor, pocket is arranged at the last back of back body and position, both sides, do not arrange pocket at stomach, belly and kidney position, form " door " font structure, the volume on described headgear, temporo, position, cheek, the neck front portion that neck puts is furnished with pocket simultaneously; Phase transition temperature be housed be 25～27 ℃ phase-change material coldness storage bag in each pocket.
Technical characterictic of the present invention also is: described phase-change material is made up of calcium chloride, sodium chloride, potassium chloride and four kinds of materials of water, and its phase transition temperature is 26.5～27 ℃.
The present invention compared with prior art has the following advantages and the high-lighting effect: the phase-change material bag is " door " font and distributes at trunk, be placed on the main muscle group of human body, as pectoralis major, latissimus dorsi etc., it is strong that this zone has the cold stimulation tolerance, the characteristics that side effect is little.Simultaneously, on phase-change material is arranged, avoided the human internal organ that to suffer from cold in the traditional Chinese medicine,, guaranteed the health of human body, the sense of discomfort of aching that avoiding suffers from cold for a long time causes as stomach, kidney etc.For human body head and neck, because the hotness susceptibility is bigger, these area arrangements phase-change material bags are lowered the temperature can obtain better cooling effect, effectively controls the overall thermal sensation.The use phase transition temperature is 25～27 ℃ a phase-change material coldness storage bag, can keep suitable heat flow between human body surface and phase-change material surface.
