PENAMBAHAN DAN VARIASI DIMENSI SIRIP ALUMINIUM PADA TUBE TERHADAP LAJU DAN EFEKTIVITAS PERPINDAHAN PANAS DALAM HEAT EXCHANGER TIPE SHELL AND TUBE
Abstract: Heat exchanger is a
device that serves to change temperature and the phase of fluid. By utilizing
heat transfer between two fluids with different temperature from the higher
temperature fluid to a lower temperature fluid. This study aims to determine
the effect of the addition aluminum fins and dimensional variations on the
effectiveness shell and tube heat exchanger. Heat Exchanger was tested by
varying the dimensions of the aluminum fins on the tube from the tube without
fins, fin tube with a length of 10 mm, 20 mm, and 30 mm. Tests carried out in
counter flow so that the heat transfer rate will be better than the directional
flow. Of the test will come out hot fluid temperature and cold fluid
temperature out. The results showed decreases in the rate of heat transfer fins
greater dimension and the dimension of the highest effectiveness without fins.
The highest effectiveness is 25.85% in tube without fins. It can be concluded
that the addition of fin in this research will reduce the effectiveness of the
heat exchanger shell and tube type.
