| Abstract: | The heat transfer performance of an array of
vertical rectangular fins perpendicularly upwards from a high temperature horizontal base was
studied under the condition of natural convection The effects of fin geometrical size on flow and
on heat transfer were discussed by means of analyzing the experimental results In the light of
the physical characteristic of the heat transfer process of the fin array ,and according to the
method of the dimensional analysis, a non-dimensional equation of calculating heat transfer
coefficient of fins was obtained by using fin spacing as feature size:Nu=01314(GrsPr)037 |

| Keywords: | Fin array Natural convection Heat transfer coefficient High temperature base |
