Heat Transfer In Natural Convection
Product Code : JA-HTLE-7376
The Heat Transfer In Natural Convection apparatus (SKU JA-HTLE-7376) shows how a heated surface loses heat to still air. A polished brass tube stands vertically inside a rectangular duct that is open at top and bottom, and an electric heating element inside the tube warms its surface. This natural convection apparatus has an acrylic window for visualisation, temperature sensors along the tube and a variac with digital meters to set and read the heat input.
Specifications
The natural convection apparatus is specified by its vertical brass tube with internal heater, open rectangular duct with acrylic window, temperature sensors with a multi-channel digital indicator and a single-phase 220 V, 2 A supply. Tube dimensions and heater rating are confirmed on the quotation.

Experiments with the natural convection apparatus
The apparatus is used to determine the average heat transfer coefficient for a vertical cylinder cooled by natural convection, from the tube surface temperatures and the electrical heat input.
- Average heat transfer coefficient in natural convection
- Surface temperature distribution along a vertical tube
- Comparison with free-convection correlations
- Heat transfer practicals for B.Tech, diploma and ITI students
Scope of supply and ordering
The listing covers the Heat Transfer In Natural Convection apparatus with brass tube, heater, duct, sensors and control panel. The user provides a table for the set-up and a 220 V supply. Accessories, spares and quantities are confirmed on the quotation.
MOQ, lead time and packing are confirmed on each quotation for the quantity and the delivery destination. Single set-ups and complete heat transfer laboratories for engineering colleges, polytechnics and ITIs, including tender orders, are supplied.
Frequently asked questions
Why is the tube polished?
To keep radiation losses low, so that the heat loss measured is mainly by natural convection.
Can the air flow be seen?
The duct has a transparent acrylic window on one side for visualisation.
What supply is needed?
Single-phase 220 V AC, 2 A.
