Thermal Convection
Mar 06, 2019

Thermal convection is the phenomenon of heat spreading from one part of a space to another through a moving medium. The larger the area of ventilation hole, the faster the velocity of heat convection. The higher the ventilation hole is, the faster the heat convection velocity is. Heat convection is an important way of heat transmission and the most important factor affecting the development of early fire. The main factors affecting heat conduction are temperature difference, thermal conductivity and the thickness and cross-sectional area of the heat-conducting object. The greater the coefficient of thermal conductivity, the smaller the thickness, the more heat conduction.
