Surface temperature uniformity of thermal manikin

Thermal manikin is equipped with heating wire which serves as internal heat source to simulate the human body heat dissipating,and mainly used for testing the thermal resistance of garments,whose surface temperature uniformity is critical.The aim of this study is to find out the main factors influencing the uniformity of the temperature on the surface of thermal manikin and how to meet the requirement of uniform distribution of the temperature.The arrangement of the heating wire and test method of the temperature are presented.Comparative experiments are conducted and temperature distribution rule on the surface of the thermal manikin is observed.The test results indicate that the laying interval of heating wire,thickness of thermal manikin′s skin cover,and the side boundary conditions on the surface all have influence on the temperature uniformity to different extents.
