Temperature profiles and heat flux over three different heat transfer surfaces can be easily studied.
The HT19 is designed for use with the Armfield HT10XC Heat Transfer Teaching Equipment.
This unit consists of a bench mounted vertical air duct positioned on the top of a centrifugal fan. The air duct incorporates an aperture positioned at the rear wall of the duct, into which three different types of heat-transfer surfaces can be inserted. The three types of heat exchanger supplied are; flat plate, cylindrical pins and finned surface.
Incorporating an electrical heating element, with positive thermal
cut-out, and thermocouples for precise temperature measurement.
The clamping mechanism ensures accurate alignment of the surface inside the duct. The front wall of the duct is acrylic, to allow viewing
of the heated surface and measurement sensors.
For forced convection, the centrifugal fan draws ambient air upward through a flow straightener and over the heated surface. A manually variable throttle controls the air flow.
An air-velocity sensor measures the air velocity inside the duct upstream of the heat exchanger.
Thermocouples measure the air temperature before and after the heated surface, together with the surface temperature at three positions along the extended surface exchangers.
On the HT19 the heater power, the air flow rate and the configuration of the heated surfaces can all be controlled via the HT10XC, either from the front panel controls or from the software.
