Description
Technical Field
The invention relates to a high-temperature operation cooling dehumidification vest applying a phase-change material and a radiation reflection film, belonging to the field of individual protection.
Background
In high-temperature and high-heat radiation operation environments without effective cooling means such as fire protection, metallurgy, summer field and the like, workers face the problem of heat stress under high-temperature operation. How to take effective measures to reduce heat stress and protect the health of operators is a popular research in the field of individual protection. The cooling system is applied to clothing worn by staff, and heat dissipation and cooling are feasible and effective measures aiming at individual individuals.
There are two general classes of ways to apply cooling systems to the wear of high temperature scene practitioners: the first type is an active cooling system, and the second type is a gas and liquid cooling system, and is characterized in that a gas or liquid coolant in a storage tank is connected with a clothing body, and a switch of the storage tank is opened to enable the coolant to enter a cavity of the clothing to exchange heat with a human body, so that the cooling effect is achieved. As in patent CN105495762a, a cooling vest is invented, which comprises a vest body, a storage tank, a flow guide pipe and the like, wherein liquid carbon dioxide is stored in the storage tank, and after the switch is turned on, the liquid carbon dioxide flows into the back core through the flow guide pipe, so that the effect of reducing the temperature of a human body is achieved. The problem of this patent lies in that cooling system is complicated, and liquid carbon dioxide holding vessel carries very inconveniently, and a plurality of accessories that relate to about liquid carbon dioxide are various complicated, very easily break down when the staff uses, lead to the holding vessel internal pressure too big thereby have the leakage risk. Another active cooling system is a solar blowing cooling vest as described in patent CN101375739a, wherein a solar power generation plate is coated on the outer surface of the vest to supply power to a light miniature high-speed fan in the vest, and the fan drives air in a pipeline in the vest to cool a human body. The problem of this patent lies in that the fan can not be operated under the condition that does not have sunny sunshine condition, can't normally cool down for the staff. The second type is a cold accumulation type passive cooling system, and the cold accumulation type is divided into two types, namely sensible heat cold accumulation and phase change cold accumulation. The sensible heat cold accumulation is to store and use cold energy by utilizing the temperature change process of a substance in the cold accumulation and heat release processes; the phase change cold accumulation is to store and use the cold energy by utilizing the energy absorbed or released by the phase change material in the phase change process. The cold accumulation type passive cooling system is characterized in that after cold accumulation of the cold accumulation material is completed, the cold accumulation material is encapsulated in a cooling back center, and the cold accumulation material is contacted with a human body to reduce the temperature of the human body. The cooling device for a vest, a cool pillow and a sun-proof cap disclosed in patent CN106165923a has the disadvantage that the used crystal mud compound cannot absorb heat generated by a human body, only has the effect of increasing the thermal resistance with an external heat source, and cannot ensure the comfort of wearing the vest when facing high temperature.
The invention uses the phase-change material after cold accumulation as a cold source, and the phase-change material generates phase change after being heated, absorbs the physiological heat and the environmental heat of the human body, and ensures that the human body is in a more comfortable temperature range; the dehumidifying agent is used for absorbing a large amount of sweat discharged by a human body in a high-temperature environment, so that the problem that sweat cannot be effectively discharged under the condition that a worker wears more clothes is solved; the aluminum foil heat-insulating coiled material is used for covering the chest and the back to emit heat radiation, so that the heat insulation effect is achieved. The invention has the advantages of comfortable wearing, large phase change latent heat, repeated use and the like, and can effectively relieve the thermal stress of a human body in a high-temperature environment.
