Updated: 2018/5/14 16:27:45

Abstract: Taking firefighter uniform with circulating cooling tube as the object of study, this paper studies its heat dispersion performance under different tube intervals, i.e., 3 cm, 3.5 cm, 4 cm, 4.5 cm and 5 cm. Results show that, tube interval has significant influence on cooling effect. When tube interval was 3.5 cm, the heating rate at tube was slow and time-consuming, and the cooling time at the space between tubes was prolonged.
