This innovative human body cooling system centers around semiconductor refrigeration

utilizing liquid circulation and a connected waterway to deliver cooling power to the human body cooling garment. By exchanging heat between the cooling garment and the human body

the desired cooling effect is achieved. To achieve a small

lightweight

portable

and highly integrated refrigeration system

this paper proposes a novel high-density toothed copper heat exchange solution on the hot end and an integrated aluminum fin water cooling system on the cold end. This design significantly reduces the volume and weight of the core refrigeration components

with the heat exchanger and refrigeration unit being seamlessly welded together

eliminating any mechanical connections and reducing the loss of cooling power caused by thermal short-circuiting

thereby enhancing the cooling capacity and conversion efficiency. The core refrigeration component has a cooling capacity of 21 W

with an efficiency of 80%

and weighs only 160 g

occupying a volume of 7×3×6 cm³. The specially designed waterway system in the cooling garment minimizes liquid flow resistance

facilitating uniform temperature distribution. Additionally

the adjustable and specialized structural design of the cooling garment ensures an effective fit for different body types

enabling ample heat exchange between the human body and the cooling garment

achieving optimal cooling effect.
