Baffles are one of the important components in heat exchangers that conduct insulation and to facilitate fluid contact in order to increase heat transfer. From previous studies, optimal baffle angle is not found yet, further research is needed of variations in appearance 50, 60, and 70 helical baffle. The purpose of this study was to determine the variation of helical baffle research on the evaluation of shell and tube heat exchanger. This study used shell and tube heat exchanger and helical baffles with helical variations of 50, 60, and 70 then the data obtained was calculated and described using tables and graphs. At 50 baffle got effetiveness 50.8%, at 60 baffle got results effectiveness 42.8 % and at the baffle 70 angle got results 31.4%. Thus, the most optimal results are in the variation of 50 because fluid would take longer to flow so that heat transfer would get better.
