This product is designed to be used in conjunction with the basic experimental platform of heat transfer to conduct verification and experimental research on the comprehensive heat transfer principles and laws of convection (natural and forced convection) and radiation in "Heat Transfer". The experimental platform is equipped with a blackbody like thermal radiation heating circular tube, based on the theoretical model of outward swept circular tube convection, and conducts comprehensive experiments related to convection and radiation by configuring air channels, fans, air volume control devices, rotatable electric heating, etc. The data is collected to the basic experimental platform of heat transfer to support experimental design within the discipline.
