Technical Field
[0001] The utility model relates to the technical field of phase change temperature control, in particular to a temperature control vest with a replaceable gel-based phase change sheet. Background Art
[0002] Under the influence of global warming and the El Niño phenomenon, high temperatures have been common around the world in recent years, with temperatures so high and lasting so long that they are rare in more than half a century. In a high-temperature environment, the health of workers is often seriously threatened. Long-term exposure to hot conditions will cause a series of physiological reactions in the human body, such as increased body temperature, increased sweating, and increased heart rate, which will not only consume a lot of energy, but may also lead to heat-related diseases such as heat stroke and heat stroke. If not treated promptly and effectively, the mortality rate of heat stroke is 20% to 60%, and the mortality rate of patients over 50 years old can be as high as 80%. In addition, a high-temperature environment will also have an adverse effect on the psychological state of workers, such as emotional reactions such as irritability and anxiety, thereby reducing their work efficiency.
[0003] In the existing technical field, although there are various protective clothing designed to improve the working comfort of workers in different environments, how to effectively regulate the human body surface temperature in a hot environment to ensure the life, health and work efficiency of workers is still an urgent problem to be solved. Traditional protective vests are often unable to effectively cope with extreme high temperature environments, making workers susceptible to fatigue, heat stroke and even life-threatening after working for a long time. Therefore, developing a vest that can regulate temperature and ensure that the human body can remain comfortable and efficient in a hot environment has important practical significance and application value.
[0004] Phase change temperature control technology is a new type of temperature control technology that has been studied in recent years. During the phase change process of the material, it can exchange energy with the external environment (absorb heat from the external environment or release heat to the external environment), thereby achieving the purpose of controlling the ambient temperature and utilizing energy. Compared with other temperature control methods, phase change temperature control has the advantages of no need for external energy, temperature control in both hot and cold environments, precise temperature control, compact size, maintenance-free, safe and reliable.
[0005] Therefore, there is a need to provide a temperature control vest with a replaceable gel-based phase change sheet, aiming to provide workers with a safer and more comfortable working environment through innovative phase change temperature control technology. Utility Model Content
