Abstract: [Purposes] In order to effctively reduce energy consumption and improve human thermal comfort in high-temperature environments,this paper proposes a lightweight and efficient thermal management strategy that can directly regulate the temperature of the human body's surrounding environment.[Methods] Firstly,a human thermal management system based on aerogel film,capillary water cooling tube and graphene film is designed.Secondly,relevant experiments are conducted to investigate the aerogel/graphene film thickness,the water flow of capillary water cooling tube,and the effect of water temperature on the average temperature diference between the system’s hot and cold surfaces.[Fingdings]The water flow rate increased from2O mL/minto4O mL/min,the temperaturedifference between the hot and cold surfaces increased from 5.5°C to 8.1 ,and the heat dissipation efficiency of the system increased. The water temperature of the capillary tube rose from 12°C to 18 °C ,the temperature difference decreased from 5.5°C to 4.3°C ,and the heat dissipation efficiency of the system decreased. The thickness of the aerogel film increased from 1.0mm to 3.0mm ,and the temperature difference rose from approximately 3.5°C to 8.2°C ,improving its heat insulation performance. The thickness of the graphene film increased from 0.10mm to 0.20mm ,the temperature difference decreased from 11.6 °C to 8.2 ℃, and its heat transfer effect was improved.[Conclusions] The research results contribute to understandingthe performance characteristics of human thermal management system,and can provide reference for the design and development of lightweight and comfortable new liquid cooling clothing.
