Structural design and performance experiment of the refrigeration device for protective clothing air supply backpack
摘要
Abstract
To address the issue of poor comfort of protective clothing in high temperature,stuffy and other environments,a refrigerated air supply backpack for protective clothing was designed and the performance experiments were conducted.The effects of the material and bottom plate thickness of the cooling profile,the size and bottom plate thickness of the heat dissipation profile on the refrigeration performance were compared by the experiment of the semiconductor refrigeration device.An integrated refrigeration device was built to study the influences of the structure of U-shape and linear air duct,the amount and position of refrigeration plate,and the different environmental temperatures on the refrigeration performance,respectively.The results show that,while meeting the basic air supply needs of the wearer,the U-shape air duct structure has better refrigeration performance.The temperature can be reduced by about 13.2℃when opening four refrigeration chips.When two refrigeration chips are opened,the refrigeration performance of the upper and lower refrigeration chips near the air outlet side is better,which can reduce the temperature by about 8.4℃.The environmental temperature mainly affects the heat dissipation performance of the refrigeration device,and then affects the cold and heat exchange of semiconductor cooler.The research content provides some reference for the application of semiconductor refrigeration technology in protective clothing.关键词
