Free and Forced Convection Manufacturer,Supplier and Exporter in India
Product Code : EL-VATP-11379
Quick Answer: The Free and Forced Convection apparatus is a bench-mounting unit with a vertical duct that holds one of three heat transfer surfaces: a flat plate, a pinned surface or a finned surface. Each surface has its own variable-power electric heater.
Last updated: October 2026
Key Features
- Three heat transfer surfaces: flat plate, pinned surface and finned surface
- Built-in variable-power electric heater in each surface
- Free convection with heated air rising up the duct, or forced convection with a variable-speed fan
- Thermocouples upstream and downstream of the surface and on the surface itself; anemometer for air velocity
- Downstream probe on a traverse to measure temperature across the duct for the bulk outlet temperature
- Extra probe for temperature along the pinned and finned surfaces; digital display of power, velocity and temperatures

About This Product
The pinned surface is similar to a tubular heat exchanger and the finned surface to the fins on air-cooled engines or electrical heat sinks, so results relate directly to familiar hardware. Students compare heat transfer from each surface in free and forced convection over a range of air velocities and heater powers. Enquiries from Antigua and Barbuda, Saudi Arabia, Botswana, Grenada, Cambodia and Maldives for the Free and Forced Convection receive an export quotation.
Frequently Asked Questions
Which surfaces are supplied with the Free and Forced Convection apparatus?
Three: a flat plate, a pinned surface and a finned surface, each with its own variable-power electric heater.
How is forced convection produced?
A variable-speed fan draws air up through the duct and across the heated surface.
