The Effect of Ambient Temperature on Human Head’s Surface Skin Temperature
头部散热 红外测温 体表面积 体表温度 Head heat loss Infrared temperature measurement Body skin area Surface skin temperature
摘要
为研究人体头部局部特征部位的散热情况, 得到局部特征部位体表温度随环境温度变化规律, 选取身体健康、 体态标准的青年男女各20名为测试对象并分成男、 女两组, 根据红外热辐射测温原理对测试对象头部选取5个局部特征部位进行测温、 记录。 控制空气湿度50%和风速0.15 m·s-1, 并以2 ℃幅度逐渐将环境温度从18 ℃升高到32 ℃。 发现健康青年女性头部各特征部位体表温度略高于男性; 男女受试者头部各特征部位体表温度在一定范围内随环境温度近似正比例变化; 运动对头部体表各部分温度影响较小且存在差异。 分析结果可应用于人体头部特征部位热流研究并对人体健康状况判断提供参考数据。
Abstract
It is important to understand heat loss from human head because human head produces much heat for its high metabolism, it also functions as a heat radiator to keep body heat balance. Heat loss from human head is closely related to its skin temperature. Therefore, skin surface temperature of human head changes with ambient temperature is studied. In this research, several positions were sampled and the advanced infrared detectors (the infrared thermal imager and the infrared thermometer) were used as tools for measurement. For the sake of comparison, the young volunteers were grouped into the boys team and the girls team. Results showed that, firstly, between the groups, there was only a little difference in that girls’ head temperature was a little higher; secondly, head temperature of either girls or boys rises with air temperature till about 30 ℃; and thirdly, exercise has only a little effect on the head temperature variation. This research is practical for further investigation on head heat flow and referential for health diagnosing by comparing the data recorded in this experiment.
