| Summary: | Nowadays an intercooler is commonly
integrated in vehicles to cool the air during induction.
However, the intercooler does not perform effectively in
countries where the climate is humid and hot as the air
temperature is relatively higher. Therefore, this study is
focused at developing an aftermarket intercooler spray to
combat this predicament. The goal of the study was to
improve the performance of a cooling-spray-integrated topmount intercooler via the analysis of nozzle diameter and
spraying angles. Experiments were conducted on five nozzle
types and three spraying angles: 00
, 150 and 300
. It was
observed that the efficiency of the intercooler with the spray
cooling unit was improved from 89.7% to 95.33%. A B1/8BX3 Hollow Cone Nozzle gave the highest efficiency, followed by
B1/8QPPA+QPHA-5 Standard Full Cone Nozzle, HB1/8VV8007 Flat Fan Nozzle, HB1/8VV-6507 Flat Fan Nozzle and
B1/8GG-4.3W Standard Full Cone Nozzle. The highest
efficiency was observed at nozzle spray angle of 150
. Nozzle
diameter and spraying angle were found critical in ensuring
an enhanced overall performance of the intercooler.
