Abstract
Efisiensi panel surya Photovoltaic (PV) di wilayah tropis sering terhambat oleh kenaikan suhu operasional yang menurunkan tegangan sirkuit terbuka dan memicu degradasi material. penelitian ini bertujuan untuk mengevaluasi kinerja termal pelat pendingin bersirip (fin cold plate) dengan membandingkan material aluminium dan tembaga, serta variasi media pendingin air distilasi dan fluida nano Zinc Oxide (ZnO) konsentrasi volume 1%. Analisis dilakukan melalui simulasi numerik Computational Fluid Dynamics (CFD) menggunakan perangkat lunak ANSYS Fluent. Pengujian dieksekusi dengan menerapkan pembebanan termal berupa heat flux konstan sebesar 700 W/m^2 dan kondisi fixed temperature pada permukaan panel 60°C, yang disimulasikan pada laju aliran 3, 5, dan 7 L/menit. Hasil simulasi membuktikan bahwa pelat tembaga mendemonstrasikan kapabilitas ekstraksi termal yang lebih superior dibandingkan aluminium, dan penggunaan fluida nano ZnO terbukti mampu mendongkrak perpindahan panas secara drastis dibandingkan air murni. Performa pendinginan paling optimal secara mutlak dicapai oleh kombinasi pelat tembaga dengan fluida nano ZnO pada debit maksimal 7 L/menit. Pada simulasi dengan kondisi heat flux, konfigurasi optimal ini menghasilkan koefisien perpindahan panas menyeluruh (U_eff) sebesar 557,20 W/m^2 K dengan tingkat efektivitas perpindahan panas memuncak pada 0,9811. Sementara itu, pada pengujian dengan kondisi fixed temperature, konfigurasi tersebut mencatatkan nilai U_eff sebesar 142,42 W/m^2 K dengan laju perpindahan panas total tertinggi mencapai 7.685,2 W.

The efficiency of Photovoltaic (PV) solar panels in tropical regions is frequently hindered by elevated operational temperatures, which reduce the open-circuit voltage and trigger material degradation. This study aims to evaluate the thermal performance of a finned cooling plate (fin cold plate) by comparing aluminum and copper materials, alongside variations in the cooling media using distilled water and Zinc Oxide (ZnO) nanofluid with a 1% volume concentration. The analysis was conducted through numerical Computational Fluid Dynamics (CFD) simulations using ANSYS Fluent software. The tests were executed by applying thermal loads in the form of a constant heat flux of 700 W/m² and a fixed panel surface temperature of 60°C, simulated at flow rates of 3, 5, and 7 L/min. The simulation results prove that the copper plate demonstrates superior thermal extraction capabilities compared to aluminum, and the utilization of ZnO nanofluid is proven to drastically boost heat transfer compared to pure water. The most optimal cooling performance is absolutely achieved by the combination of the copper plate and ZnO nanofluid at a maximum flow rate of 7 L/min. In the simulation under heat flux conditions, this optimal configuration yields an overall heat transfer coefficient ($U_{eff}$) of 557.20 W/m²K, with the heat transfer effectiveness peaking at 0.9811. Meanwhile, in the test under fixed temperature conditions, this configuration recorded a $U_{eff}$ value of 142.42 W/m²K, with the highest total heat transfer rate reaching 7,685.2 W.
