Description
Technical Field
A human body protection system based on a phase change material and suitable for the environment in a tank belongs to the field of special equipment environment control.
Background
Armored forces are combat forces in the army which are basically equipped with tanks and other armored vehicles. The armored vehicles and the tanks are mainly medium-sized and micro-sized, and the maximum internal temperature of the vehicles can reach about 60 ℃ due to heat dissipation of vehicle engines, heat dissipation of equipment in a battle room, sunlight irradiation and internal space sealing, so that how to guarantee physical performance of fighters in specific spaces of the armored vehicles and the tanks and the problem that the fighters face heat stress in a high-temperature environment become urgent. The cooling system is applied to the clothes worn by workers, and the cooling system is a feasible and effective measure for radiating and cooling individual bodies, so that the prior case of applying the related technology to the battle of armored vehicles does not exist at present.
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. For example, patent CN105495762A discloses a cooling vest, which comprises a vest body, a storage tank, a flow guide tube, etc., wherein liquid carbon dioxide is stored in the storage tank, and the liquid carbon dioxide flows into the vest through the flow guide tube after a switch is turned on, thereby achieving the effect of reducing the temperature of the human body. 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 break down when using, thereby lead to the too big risk of leaking of holding vessel internal pressure. Another active cooling system is to complete cooling through an electric drive fan, for example, in 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 micro high-speed fan in the vest, and the fan drives the air in the pipeline in the vest to cool the human body. The protective clothing consumes electric energy and needs battery storage, and the waste battery is easy to cause secondary pollution to the environment; the whole weight is close to 10kg, and the human body load is increased; and because sweat is discharged, the electric leakage risk is generated, and the special environment of the armored vehicle cannot be adapted.
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 the vest to cool the vest, the cool pillow, and the sun hat, and the used crystal clay compound particles cannot absorb heat generated by the human body, and only increase the thermal resistance between the crystal clay compound and the external heat source, so that the comfort of wearing the vest at high temperature cannot be ensured.
The invention abandons the traditional air circulation type ventilation and directly utilizes Na2SO4·10H2The characteristic of O phase change reaction establishes that no power supply is neededPassive thermal protective clothing. Compare traditional cooling clothes that use the fan, the hot protective clothing cost that this patent relates to is lower, and the live time is of a specified duration, and it is strong to need not power security, and noiselessness can effectively reduce human body and feel the temperature in 4 hours under the high temperature environment more than 50 ℃, and has designed the tank cap of using phase change material alone and be used for the supplementary cooling of head, and overall design can bring safer guarantee and more comfortable experience for the user.
