In extreme high-temperature environments such as metallurgy, firefighting, and chemical smelting, the thermal protection performance of protective clothing directly impacts workers’ safety and efficiency. Traditional human testing carries risks of heatstroke and data variability. Thermal manikins, equipped with biomimetic heat simulation technology, create a “digital safety laboratory” to make thermal protection measurable, analyzable, and reliable.
For extreme environments ranging from 40°C to 120°C, thermal manikins integrate full-dimensional thermal response systems with high-precision sensor arrays, accurately simulating human heat production, dissipation, and heat stress under high-temperature conditions, establishing a standardized testing framework for the industry.
High-Temperature Adaptability: The manikin’s intelligent temperature control system ensures stable operation in up to 45°C environments. It can simulate complex heat flux conditions of 0–10 kW/m², suitable for outdoor engineering, steel hot-rolling, and other medium-high temperature scenarios.
Biomimetic Heat Production & Dissipation: Dozens of independent heating modules simulate metabolic heat from resting (50 kcal/h) to high-intensity work (500 kcal/h). In a 45°C humid environment (60% RH), the manikin can precisely control skin sweat evaporation (0–2 L/h adjustable), replicating the human “heat generation – convection – evaporative” cooling mechanism with ≤±1.5% error.
Millimeter-Level Heat Stress Monitoring: Real-time monitoring of skin surface temperature (±0.1°C) and core temperature captures thermal anomalies at vulnerable areas such as collars and cuffs. Local temperature increases as small as 0.5°C can be identified.
Case Simulation: 45°C Dry Heat + Light Activity (200 kcal/h)
Thermal Radiation Insulation: At a heat flux of 5 kW/m² (equivalent to high summer solar radiation), premium garments maintain average skin temperature ≤39°C (comfort threshold 40°C) and core temperature fluctuation ≤0.8°C over 8 hours. Ordinary products exceeded 42°C within 2 hours, with core temperature rising 0.5°C every 30 minutes, posing heatstroke risks.
Sweat Evaporation & Cooling Efficiency: In 45°C, 50% RH conditions, poorly breathable garments showed inner-layer humidity rising to 85% within 1 hour, reducing evaporative cooling efficiency by 50%.
Dynamic Heat Tolerance During Activity: Simulated frequent joint movements revealed fabric stretch at elbows and knees increased heat penetration by 15%. Optimized 3D-cut garments reduced peak skin temperature by 3°C and lowered joint heat loss by 20%, preventing localized overheating during motion.
For summer outdoor work, the manikin can be configured with 45°C environment, 6 kW/m² heat flux, and high humidity, assisting enterprises in developing lightweight protective clothing that balances insulation and breathability, addressing both sweat retention and burn risk. Every degree of temperature and every detail is quantified, reinforcing a technological safety barrier for high-temperature operators.
