Abstract
A human body heat protection suit and a method applying phase change materials for express takeoffs belong to the field of individual protection. The present invention utilizes Na2SO4·10H2The characteristic of O phase change reaction, and the addition of the auxiliary agent and the nucleating agent simultaneously prolongs the phase change period and has higher latent heat, thereby constructing the passive heat protective clothing. The protective clothing combines detachable armguard, evenly arranges the phase change material module on protective clothing and armguard, guarantees express delivery take-out personThe thermal comfort level is good in the environment of high-temperature operation in summer. When the invention is implemented, Na is added when the temperature of human body and the external temperature reach the phase transition temperature2SO4·10H2O is changed from solid to liquid, absorbs the heat of the cooling suit in the phase change process, and reduces the temperature of the cooling suit and the temperature of a human body after the phase change is finished, so that the heat comfort balance of the human body is ensured; can dismantle the armguard simultaneously and can satisfy express delivery take-out personnel's hot protection demand of hand, design the elastic cord in armguard wrist part, can freely contract and reduce the heat of environment and enter into inside the armguard, guarantee human comfort.
Description
Technical Field
A human body heat protection garment and a method for applying phase change materials to express takeoffs belong to the field of individual protection.
Background
The summer high-temperature operation has been common, and in the high-temperature and high-heat radiation operation environment without effective cooling means, such as fire fighting, metallurgy, summer field and the like, workers face the heat stress problem under the high-temperature operation. How to ensure good working state of personnel such as takemen, cleaners and security guards when working in high temperature environment is a social hotspot problem. The cooling system is applied to the clothes worn by workers, and heat dissipation and cooling for individual bodies are feasible and effective measures.
Currently, cooling systems are applied to wearing of high-temperature scene practitioners in two ways: the first type is an active cooling system, and the first type is a gas and liquid cooling system, which is characterized in that gas or liquid coolant in a storage tank is connected with a garment body, and a storage tank switch is opened to enable refrigerant to enter a cavity of the garment to exchange heat with a human body, so that the cooling effect is achieved. A cooling undershirt is invented like patent CN105495762A, including undershirt body, holding vessel, honeycomb duct etc. and there is liquid carbon dioxide in the holding vessel, and liquid carbon dioxide passes through the honeycomb duct and flows into the vest after the switch is opened, plays the effect that reduces human body temperature. This patent problem lies in that cooling system is complicated, and liquid carbon dioxide holding vessel carries very inconveniently, and a plurality of accessories about liquid carbon dioxide that involve are numerous complicated, very easily breaks down when the staff uses, thereby leads to the too big risk of leaking of holding vessel internal pressure. Another active cooling system is to drive a fan to complete cooling through electric power, for example, in the patent CN101375739A, a solar blowing cooling vest is provided, in which a solar power generation panel 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 the air in the pipeline in the vest to cool the human body. The problem of the patent is that the fan cannot operate under the condition of no sunshine in fine days, and the temperature of workers cannot be reduced normally.
The second type is a cold accumulation type passive cooling system, and the cold accumulation type is divided into sensible heat cold accumulation and phase change cold accumulation. The sensible heat cold accumulation is to realize the storage and the use of cold energy by utilizing the change process of the temperature 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 using 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 the cold accumulation material is packaged in the cooling back core after cold accumulation is finished, and the cold accumulation material is in contact with a human body to reduce the temperature of the human body. For example, in the CN106165923A patent, the crystal clay compound particles are used as a cold source and placed in articles such as vests to perform the cooling function, but the used crystal clay compound cannot absorb heat generated by human bodies, only plays a role of increasing thermal resistance between the crystal clay compound and an external heat source, and cannot ensure the comfort of wearing vests at high temperature.
The heat protection suit is constructed by directly utilizing the characteristic that the physical material absorbs heat in a phase change manner, and compared with gas, liquid and electric power cooling protection suits, the heat protection suit has the advantages of no need of a power supply, low cost, long service time, strong safety and no noise, and brings safer guarantee and more comfortable experience to users; compared with the existing cold storage type passive heat protection clothes, the cold storage type passive heat protection clothes have the advantages that the duration is longer, the material layering phenomenon is not easy to occur, the phase change material is more uniformly distributed on the surface of a human body, and the wearing is more comfortable.
