Free and Forced Convection Manufacturer,Supplier and Exporter in India
Product Code : EL-VATP-11379
The bench-mounting equipment includes a vertical duct that holds the chosen heat transfer surface and all instruments needed.
Include three different common heat transfer surfaces with the equipment:
A Flat Plate.
A Pinned Surface – similar to a tubular heat exchanger.
A sensitive anemometer measures the air velocity.
A Finned Surface – similar to the fins on air-cooled engines or electrical heat sinks.
Each surface has its own built-in variable-power electric heater.
Students choose which surface they need to test and fit it to the duct using simple fixings.
For free convection tests, the heated air rises from the surface and up the duct.
For forced convection tests, a variable-speed fan draws air up through the duct and across the surface. Thermocouples measure the air temperature upstream and downstream of the surface and the temperature at the heat transfer surface.
Two controls allow students to set different air velocities and heater power for a full range of tests.
A digital display shows the heater power, air velocity and the temperatures measured by the thermocouples.
The downstream probe moves in a traverse mechanism to measure the temperature distribution across the duct, allowing calculation of the bulk outlet temperature.
An additional probe allows students to measure the temperature distribution along the extended surfaces of the pinned and finned heater transfer surfaces.
