As used herein, the term 'phase change material' is well known as PCM (phase change material). This refers to a material other than water that causes a phase change at 0 °C, for example, the state of the material changes at a temperature desired by the user, such as 5 °C, 10 °C, 18 °C, 22 °C, 28 °C, 32 °C to 48 °C. It refers to a material that can absorb or release a lot of heat while doing so. This material mainly uses latent heat and is also called heat storage material. In general, PCM can be classified into hydrocarbon-based organic substances such as tetradecane, octadecane, and nonadetane, inorganic substances such as calcium chloride in the form of hydrates, and plant substances that can be obtained from nature. According to a study by the National Aeronautics and Space Administration (NASA), it is reported that there are about 100 to 200 types of PCM that are practically applicable. Originally, PCM was developed to protect spaceships and astronauts from external temperature changes, but in recent years, it has been widely applied to general consumers, such as heating and cooling systems using PCM for room temperature (5℃ heat storage).

The 'phase change material' according to the present invention is a material that causes a phase change at a specific temperature selected from 5° C. to 48° C., and may be used without limitation, especially if there is no volatility and there is no alcohol component. If there is volatility, the period of use may be limited because the volatilized gas component penetrates through the thermoplastic polyurethane film and is emitted. Because.

The temperature range of the phase change material of the cooling vest 10 provided according to the present invention can be selected from various temperature ranges according to the wearer's use environment or external temperature factors.

For example, a phase change material having a specific temperature range of 5 ℃ or 10 ℃ or 18 ℃ can be used by filling the cooling vest (10). In the case of such a temperature range, it is advantageous for rapidly recovering to normal body temperature when body temperature rises rapidly, so it can be used for athletes, construction sites, vinyl house workers, and hot summer days.

In addition, a phase change material having a specific temperature range between 20 ℃ ~ 32 ℃ can be used by filling the cooling vest (10). Such a temperature zone may cause serious thermal problems due to an increase in internal temperature if, for example, quarantine medical personnel or firefighters work for a long time while wearing protective clothing and firefighters to perform their duties. For this purpose, it is advantageous to restore the body temperature to normal body temperature by wearing the cooling vest 10 on the body and wearing a protective clothing or firefighting suit on the outside.

In addition, a phase change material having a specific temperature range between 32 ° C and 48 ° C can be used by filling the cooling vest 10 . When the body is exposed to a cold temperature, such a temperature range can be advantageously used to keep the body warm, for example, when the body temperature falls under the influence of an external environment, such as a scuba diver who sneaks in cold water or a skier in winter.

As described above, the cooling vest 10 of the present invention can be manufactured by filling a phase change material that causes a phase change at a specific temperature selected from 5° C. to 48° C. according to the wearer's use environment or external temperature factors.

In the above, the present invention has been described with reference to a specific embodiment, but those skilled in the art can make various and modified configurations by referring to and combining various features described in this specification. Therefore, it is pointed out that the scope of the present invention is not limited to the described embodiments, but should be construed by the appended claims.
