Natural convection and Radiation Manufacturer,Supplier and Exporter in India
Product Code : EL-EE-12183
Quick Answer: Natural Convection and Radiation is a heat transfer test unit in which a polished vertical brass tube, heated from inside by an electric element, loses heat to the air in a rectangular duct by natural convection.
Last updated: October 2026
Key Features
- Brass tube mounted vertically in a rectangular duct open at the top and bottom
- Acrylic window on one side of the duct for visualisation
- Heating element inside the tube raises the tube surface temperature
- Polished tube surface to minimise radiation losses
- Multichannel digital temperature indicator reads the tube temperature sensors
- Variac controls the heat input shown on a digital ammeter and voltmeter

About This Product
Heat transfer practicals often start with a heated vertical cylinder in still air. In this unit the duct keeps draughts away, the acrylic window lets students view the set-up, and the sensors with a multichannel selector let them note the tube temperatures at each heater setting. The ammeter and voltmeter readings give the electrical heat input. It is used in mechanical and thermal engineering classes to show how a hot surface loses heat to the air around it. The Natural Convection and Radiation can be supplied and exported to buyers in Albania, Mauritius, Barbados, Laos and Trinidad and Tobago.
