Natural and forced convection heat transfer experimental apparatus
This is a tabletop experimental device that conducts experiments on natural convection, forced convection, and heat transfer using heater modules with different surface shapes. The device consists of a duct measuring 128mm x 75mm, a removable fan, and three types of heater modules. Three thermocouples measure the temperature at the inlet and outlet of the duct, as well as the surface temperature of the heater modules. Additionally, a manual thermocouple is included to measure the surface temperature at six locations along the module from the side of the duct. The measured temperatures and wind speeds are displayed in real-time on a digital display. Furthermore, by using an optional (sold separately) data acquisition system (VDAS-B), various data can be collected and analyzed in real-time on a PC (sold separately).
