AFT149 Free and Forced Convection: The Essential Educational Equipment for Heat Transfer Studies
Understanding the principles of thermodynamics is a cornerstone of engineering education. Among the three major heat transfer modes—conduction, radiation, and convection—convection often presents the most dynamic challenges for students to grasp. To bridge the gap between theoretical knowledge and practical application, the AFT149 Free and Forced Convection unit stands out as a premier piece of Educational Equipment designed specifically for comprehensive laboratory instruction.
I.Product Introduction
The AFT149 is a compact, benchtop Teaching Equipment unit that allows students to visualize and analyze both natural and forced convection. Natural convection occurs due to density variations caused by uneven temperature fields within a fluid, while forced convection is driven by external forces such as fans or pumps. This Didactic Equipment enables learners to observe these phenomena in real-time, making abstract concepts tangible.
At the heart of this Vocational Training Equipment is a vertical pipe with a detachable heating element. The system is thoughtfully engineered with multiple sensors, including a handheld temperature probe, a waterproof electrical adapter box, and a power supply box. A temperature sensor (T1) and an anemometer are positioned at the lower air inlet, while a 24V adjustable axial fan sits at the upper air outlet. The handheld probe (T3) can be inserted into reserved holes in the middle of the duct, offering flexibility in measurement.
II.Technical Specifications
One of the standout features of this Technical Teaching Equipment is its modular design. The vertical pipe accommodates three distinct types of heating elements, each equipped with its own temperature sensor (T4). These include a tube bundle heat exchanger with 23 tubes and a heating power of 20W (heat transfer area: 31.41 cm²), a cylindrical heat exchanger with uniform surface temperature available in 20W (111 cm²) and 40W (2 x 100 cm²) variants, and a cylinder with a heating foil rated at 40W (111 cm²).
This versatility makes the AFT149 an exceptional piece of Industrial Training Equipment. The unit operates on AC230V 50Hz power, features a flow cross-sectional area of 120x120mm, and stands approximately 0.6 meters tall. The axial fan delivers a maximum flow rate of 500m³/h, a maximum pressure difference of about 950Pa, and consumes 90W. The system supports air speeds from 0 to 10 m/s, temperature measurements from 4x 0 to 325°C, and heating power from 0 to 50W. It requires an ambient temperature of -10°C to +40°C and relative humidity below 85%.
III.Accessories and Practical Application
As a piece of Technical Training Equipment, the AFT149 is built to meet rigorous experimental teaching requirements. The package includes a cylinder with uniform surface temperature, a bundle-type experimental module, a cylinder with heating foil, a flat-type experimental module, sensor data cables, a USB data cable, a power cable, and a USB flash drive. The unit’s overall dimensions are 680mm x 390mm x 920mm, and it weighs less than 30KG, making it both sturdy and space-efficient.
The dedicated software provided with this Technical Skills Training Equipment allows users to quickly obtain and analyze experimental data. The product is designed to be plug-and-play, with fast-install accessories and a beautiful, durable construction.
For institutions seeking reliable and versatile Educational Equipment that seamlessly integrates theory with practice, the AFT149 Free and Forced Convection unit is an outstanding choice. Its robust design, modular components, and comprehensive experiment list make it an indispensable asset for any Teaching Equipment laboratory focused on thermodynamics, heat transfer, and fluid mechanics. Whether used in vocational training or university-level engineering courses, this Didactic Equipment ensures that students gain the practical skills and conceptual clarity needed to excel in their fields.
