2 Terminologi Suatu alat yang memungkinkan perpindahan panas dan bisa berfungsi sebagai pemanas maupun sebagai pendingin dengan cara kontak tidak langsung Tipe aliran pada HE Counter current flow (aliran berlawanan arah) Paralel flow/co current flow (aliran searah) Cross flow (aliran silang) Cross counter flow (aliran silang berlawanan) Jenis-Jenis HE : Plate and Frame Heat Exchanger Shell and Tube Heat Exchanger Adiabatic wheel heat exchanger Pillow plate heat exchanger Dynamic scraped surface heat exchanger Phase – change heat exchanger Double Pipe Heat Exchanger

3 Faktor yang Mempengaruhi Perancangan
Jenis fluida yang digunakan, baik itu fisik maupun kimia Temperatur Tekanan Fouling factor Luas Area Velocity

4 Formulasi Perancangan
Log Mean Temperature Difference Temperature correction factor Mean Temperature Difference Provisional Area Number of Tube

5 Tube Pitch and Bundle Diameter
Shell Diameter and Baffle Spacing Area for Cross-flow Shell Side Mass Velocity Shell Side Equivalent Diameter

6 Shell Side Prandtle and Reynold Number
Shell Side Heat Transfer Coefficient Pressure Drop in Shell Number of tubes per pass Tube Side Mass Velocity Tube Side Velocity Prandtle and Reynold Number for Tube

7 Heat Transfer Coefficient
Overall Heat Transfer Coefficient Factor Tube Side Pressure Drop
