ATENG 12839 — Free and Forced Convection Heat Transfer Equipment
Bench-top unit.
Anodized aluminum frame and panels made of painted steel.
Main metallic elements made of stainless steel.
Diagram in the front panel with distribution of the elements similar to the real one.
- Stainless steel tunnel of rectangular section, 700 mm long, painted and resistant to
corrosion.
In the tunnel three type of different heat exchangers can be set.
Methacrylate viewer that allows a good visualization of the exchanger that is in use.
Stabilizers to guarantee an uniform air flux.
- Eight temperature sensors, (“J” type):
Two temperature sensors measure the air temperature at the inlet and outlet of area of ATENG 12839 detail
heat exchange.
Included exchangers
Temperature measurements, at different distances of the base of the pins and fins exchangers,
are made by five temperature sensors that are introduced by one side of the tunnel.
Temperature sensor in the exchangers.
- Maximum working temperature: 120 °C.
Flow sensor for measuring the air flow generated.
- Three aluminum exchangers:
- Flat heat exchanger: 100 x 100 mm. Flat exchanger
- Pins heat exchanger: seventeen pins, each one of 10 mm diameter and 125 mm longitude.
- Fins heat exchanger: nine fins, each one of 100 x 125 mm.
- Variable power heating element: 150 W for each exchanger.
- Variable speed fan, which generates air flux through the tunnel, range: 0 – 1200 l/min.
