Penelitian ini bertujuan untuk membandingkan kinerja pola aliran searah (parallel flow) dan berlawanan (counter flow) pada heat exchanger tipe shell and tube skala laboratorium. Metode yang digunakan adalah eksperimen dengan memanfaatkan air sebagai fluida panas maupun fluida dingin. Variabel utama yang diamati meliputi temperatur masuk dan keluar fluida panas serta fluida dingin, waktu operasi, serta efektivitas perpindahan panas yang dianalisis menggunakan pendekatan Log Mean Temperature Difference (LMTD). Hasil penelitian menunjukkan bahwa konfigurasi aliran berlawanan menghasilkan kinerja perpindahan panas lebih baik dibandingkan dengan aliran searah. Hal ini ditunjukkan oleh temperatur keluar fluida panas yang lebih rendah (68,9°C dibandingkan 70,7°C) dan temperatur keluar fluida dingin yang lebih tinggi (44,1°C dibandingkan 41,9°C). Meskipun waktu perpindahan panas pada aliran berlawanan lebih lama (5,61 menit) dibandingkan searah (4,55 menit), efektivitas perpindahan panas pada konfigurasi aliran berlawanan tetap lebih tinggi. Dengan demikian, pola aliran berlawanan direkomendasikan sebagai konfigurasi yang lebih efisien dalam meningkatkan performa heat exchanger tipe shell and tube, baik sebagai media pembelajaran maupun untuk aplikasi industri skala kecil.
