Abstract

Disclosed are an item of human body thermal protective clothing for delivery men using phase change materials and a method therefor, which belongs to the field of individual protection. An item of passive thermal protective clothing is made by utilizing the properties of the phase change reaction of Na2SO4·10H2O, while an auxiliary and a nucleating agent are also added thereto to prolong the phase change cycle and makes same possess a higher latent heat. An item of protective clothing (17) is combined with a detachable arm guard, and the phase change material module is uniformly arranged on the protective clothing (17) and the arm, which guarantees that delivery men can have a good thermal comfort in the high-temperature operating environment experienced during summer. When the human body temperature and the external temperature reach the phase transition temperature, Na2SO4·10H2O turns into a liquid state from a solid state, and absorbs the heat from the protective clothing (17) during the phase change process; and after the phase change is finished, the temperatures of the protective clothing (17) and the human body decrease, ensuring the thermal comfort balance of the human body. Furthermore, the detachable arm guard can meet the hand thermal protection needs of delivery men, and the wrist part of the arm guard is designed with an elastic band, which can be retracted freely to reduce the amount of environmental heat entering the interior of the arm guard, thereby ensuring the comfort for a human body.

Description

Human body thermal protective clothing and method for applying phase change material to express delivery staff

Technical field

A thermal protective clothing and method for human body using phase change materials for express delivery workers belong to the field of personal protection.

Background technique

The occupation of high-temperature operations in summer has become very common. In the high-temperature and high-heat radiation working environment where there is no effective cooling method such as fire fighting, metallurgy and summer field, workers are faced with the problem of heat stress under high-temperature operations. How to ensure that the delivery staff, cleaners, security personnel and other personnel work in a high temperature environment to ensure good working conditions is a hot social issue. It is a feasible and effective measure to apply the cooling system to the clothing worn by the staff, and to conduct heat dissipation and cooling for individual individuals.

At present, there are two ways to apply the cooling system to the clothes of employees in high temperature scenes: the first type is an active cooling system, and the first type is a gas and liquid cooling system, which is characterized by combining the gas or liquid coolant in the storage tank with The clothing body is connected, and the storage tank switch is turned on to allow the refrigerant to enter the cavity of the clothing to exchange heat with the human body, thereby achieving the effect of cooling. For example, the patent CN105495762A invented a cooling vest, including the vest body, storage tank, draft tube, etc., liquid carbon dioxide is stored in the storage tank. After the switch is turned on, the liquid carbon dioxide flows into the vest through the draft tube, which reduces the body temperature. Effect. The problem of this patent is that the cooling system is complicated, the liquid carbon dioxide storage tank is very inconvenient to carry, and the multiple accessories related to the liquid carbon dioxide involved are various and complicated, and it is easy to malfunction when the staff uses it, resulting in excessive pressure in the storage tank and risk of leakage. . Another active cooling system is to drive a fan to complete the cooling. For example, a solar blowing cooling vest described in the patent CN101375739A, the light micro high-speed fan in the vest is powered by a solar panel on the outer surface of the vest. Drive the air in the pipeline in the vest to cool the human body. The problem with this patent is that the fan cannot operate without sunny conditions and cannot cool the staff normally.

The second type is a cold storage passive cooling system. The cold storage type is divided into two types: sensible heat storage and phase change cold storage. Sensible heat storage is the use of the temperature change process of the substance itself in the process of cold storage and heat release to realize the storage and use of cold energy; phase change cold storage uses the energy absorbed or released by the phase change material in the phase change process to carry out "cold energy" "Storage and use. The cold storage passive cooling system is characterized in that the cold storage material is packaged in a cooling vest after the cold storage is completed, and the cold storage material contacts the human body to reduce the temperature of the human body. As described in the patent CN106165923A, a cooling device for vests, cool pillows, and sun hats, the crystal mud compound particles are placed as a cold source in vests and other items to cool down. The disadvantage is that the crystal mud used The compound cannot absorb the heat generated by the human body, and only serves to increase the thermal resistance between the external heat source, and cannot guarantee the comfort of the vest when faced with high temperatures.

This patent directly uses the characteristics of phase change of physical materials to absorb heat to construct thermal protective clothing. Compared with gas, liquid and electric cooling protective clothing, its advantages are that it does not require power supply, lower cost, long use time, strong safety, and no noise. , To bring users a safer guarantee and a more comfortable experience; Compared with the existing cold storage passive thermal protective clothing, its advantages are that it lasts longer, is not prone to material delamination, and phase change materials are in the human body. The surface is more evenly distributed, and it is more comfortable to wear.
