Comparing Armfield HT30XC and Armfield HT30X
The Armfield HT30XC and Armfield HT30X are both heat transfer apparatus designed specifically to teach and demonstrate thermal conductivity. Both of these models are tried, tested and accepted by engineers and teaching institutions around the world. The HT30XC utilises electrical heating while the HT30X applies hot oil as the primary source of heat.
Both apparatus feature a core section where the heating element is situated and insulated panels which are identical in length and width but differ in terms of insulation thickness by a factor of two. This generates two different thermal reservoirs with differing clearance gaps. The annular pipe serves to connect the core section to the reservoir and provide an effective circulation path for the hot fluids. A variety of configurations are possible with the HT30X due to the interchangeable pipe sections and temperature sensor.
The core section of the HT30XC comprises a resistive heating element with an adjustable temperature controller. The die-cast heating element is also interlinked with a top mounted fin assembly for improved heat transfer. An adjustable flow control valve and air-cooled fan provides additional control of the unit. In addition, the HT30XC includes an external controller which monitors the temperature of the hot water and records the readings on a graphic display so users can easily compare their findings.
The HT30X on the other hand utilizes hot oil as a medium of heat transfer. This apparatus features a practical demonstration unit that is used to introduce students to heat transfer by convection. The model comes with an adjustable differential controller and an annular pipe to effect flow of the hot oil. The temperature can be monitored and recorded using the LED display and a chart recorder, respectively. Users can also adjust the temperature using a range of oil inlets and adjust the flow rate using the variable flow control valves mounted on the base.
In summary, both the Armfield HT30XC and Armfield HT30X are valuable tools when it comes to teaching and demonstrating heat transfer. The HT30XC is designed with an adjustable temperature controller which allows users to easily adjust the temperatures and record their findings. The HT30X features an adjustable flow control valve and annular pipe which makes it ideal for demonstrating heat transfer by convection. Both models are durable and have been accepted by teaching institutions around the world.
