Pin Fin Apparatus
Product Code : EL-HTL-11082
Quick answer: The pin fin apparatus is used to measure the temperature distribution, heat transfer coefficient and effectiveness of a pin fin in natural and forced convection. Interchangeable mild steel, brass and aluminium fins are heated at the base, with five thermocouples along the fin and a blower for forced air. Lab Exports manufactures it in Delhi for engineering colleges, polytechnics and TVET institutes.

How the pin fin experiment is done
A fin adds surface area so that more heat can leave a hot body by convection. Heat flows along the fin by conduction and leaves its surface to the air, so the temperature falls from base to tip. For a fin with an insulated tip the excess temperature follows theta / theta0 = cosh(m (L - x)) / cosh(m L), with m = sqrt(h P / (k A)), where P is the perimeter and A the cross-section.
The fin material sets how far the heat travels. Aluminium and brass, with high conductivity, stay warm further along their length than mild steel and so dissipate more heat. Fitting each fin in turn, with the window open for natural convection or the blower running for forced convection, lets students compare h, fin efficiency and effectiveness under both conditions.
- Fit a fin, switch on the heater and set the input with the dimmerstat.
- For natural convection, leave the window above the fin open and wait for steady state.
- Record the five fin temperatures, the air temperature and the heater input.
- For forced convection, start the blower, set the airflow and read the orifice meter manometer.
- Repeat for each fin material and compare the measured profile with theory.
