摘要

In order to obtain the thermal physical parameters of heat transfer in Chinese kang, the ?uid-solid coupling heat transfer is analyzed through the Fluent and Static Structural modules in ANSYS. The indoor temperature fieldchanges under different external in?uences are obtained, and the distribution characteristics of the severity of the thermal damage area of the kang body are basically grasped. The temperature distribution in the heated area of the Chinese kang is not uniform, and the temperature of the kang body changes more slowly than air. One hour after the heating is stopped, the temperature of the kang body can still continue to rise. The equivalent elastic strain value near the smoke heating area is higher, and the value is between 1.2752 × 10- 12–1.5939 × 10- 12 m/m. This area has a higher risk of thermal damage and structural deformation. The traditional Chinese kang has good thermal inertia and has a 5 h warmth retention effect after heating is stopped.
