Disposable protective clothing based on semiconductor refrigeration and PCM cold storage temperature control

Abstract

The invention provides a disposable protective garment based on semiconductor refrigeration and PCM cold storage temperature control, which comprises: a protective garment shell device, wherein the protective garment shell device is of an upper clothing and lower clothing connecting structure, and a groove shell assembly is arranged at the connecting position of the upper clothing and the lower clothing; a refrigeration heat exchange device which is embedded into a groove shell assembly arranged on the protective clothing shell device through a fixing assembly and comprises a PCM cold storage module used for transferring cold energy and absorbing heat; a fixing assembly which comprises a position buckle structure and a clamping buckle structure and is used for connecting the protective clothing shell device and the refrigeration and heat exchange device; a sealing waistband device which is connected with the groove shell assembly in the protective clothing shell device and used for fixing and sealing the refrigeration heat exchange device and conducting internal circulation heat exchange; and a feedback control device which is arranged outside the protective clothing shell device, is connected with the refrigeration heat exchange device and the sealing waistband device through circuits, and is used for man-machine exchange control and continuous supply of electric energy. The disposable protective garment has the advantages of being light in function integration, good in refrigeration and heat exchange effect and convenient to move.

Description

technical field [0001] The invention relates to the technical field of clothing refrigeration, in particular to a disposable protective clothing based on semiconductor refrigeration and PCM cold storage and temperature control. Background technique [0002] As the COVID-19 epidemic spreads all over the world, due to the special working environment requirements, the vast number of medical workers must isolate themselves from the virus to protect themselves, and their whole bodies need to be wrapped in closed protective clothing. However, under such protection requirements, the heat on the body surface cannot be dissipated. In addition to the busy work content, medical staff wear protective clothing for at least 5 hours, and as many as ten hours. They are always sweating and drenched. Even heatstroke occurs, so this problem needs to be solved urgently. Traditional fan cooling and ice cooling, due to the closed design of protective clothing, have poor cooling effects and canno...

AI Technical Summary

Problems solved by technology

However, under such protection requirements, the heat on the body surface cannot be dissipated. In addition to the busy work content, medical staff wear protective clothing for at least 5 hours, and as many as ten hours. They are always sweating and drenched. Even heat stroke occurs, so this kind of problem needs to be solved urgently

Traditional fan cooling and ice cooling, due to the closed design of the protective clothing, the cooling effect is poor, which cannot solve the problems of medical staff

[0003] The existing "air-cooled vest" on the market, its main structural form is to wear a vest inside the clothes, and hang a fan convection ice bag on the back to cool down. However, in this way, the cooling time is short, the transmission range is small, and the heat cannot be discharged after absorption. , It is not easy to replace the ice pack and other shortcomings

Another kind of "air-conditioning suit" is to transfer the cold energy of the evaporator of the air conditioner to the surface of the body through the water medium. However, this method requires external heavy-weight refrigeration equipment, and limits the movement, which is not conducive to workers who move frequently. Poor ease of use
