Abstract:
We analyzed the thermal performance of louvered fin heat
exchanger with equal and unequal louver pitch which
continuously increased by 20% from air inlet area to the
redirection region and difference of thermal performance of the
louvered fin heat exchanger with unequal louver pitch was
compared with that of equal louver pitch. The frost blocking of
the spaces between louvers at front side of the louvered fin heat
exchanger with unequal louver pitch was delayed and the time,
the heat transfer rate of louvered fin heat exchanger reached
50% of the maximum heat transfer rate, of the unequal louver
pitch louvered fin heat exchanger was also delayed than that of
the equal louver pitch louvered fin heat exchanger. The
operating time of louvered fin heat exchanger with unequal
louver pitch was longer than that of equal louver pitch and the
total heat transfer until reaching 50% of the maximum heat
transfer rate increased at 18% than that of equal louver pitch.
