Abstract

Studi ini menyelidiki kinerja kotak pendingin portabel 66 liter yang menggunakan modul ThermoelectricCooler (TEC) (TEC-12715). Desain eksperimental mengevaluasi dua konfigurasi utama: susunan satu lapis yang menggunakan 14 modul TEC dan susunan dua lapis yang menggunakan 10 modul TEC, yang diuji dalam kondisi tanpa beban dan beban penuh selama 120 menit. Metrik kinerja, termasuk pengurangan suhu dan Koefisien Kinerja (COP), dianalisis secara komprehensif. Hasil menunjukkan bahwa konfigurasi satu lapis memberikan stabilitas termal yang lebih unggul. Dalam kondisi tanpa beban, konfigurasi ini mencapai suhu internal minimum -3,74°C dengan COP rata-rata 10,44, sedangkan dalam kondisi beban penuh, konfigurasi ini mempertahankan suhu -2,94°C dengan COP rata-rata 10,39 tanpa mengalami kegagalan termal. Sebaliknya, konfigurasi dua lapis menunjukkan pendinginan awal yang lebih cepat tetapi mengalami ketidakstabilan termal yang melonjak selama operasi jangka panjang. Pada beban penuh, suhu optimal mencapai -1,47°C pada menit ke-95 dengan COP rata-rata 1,49, sebelum mengalami pelarian termal kritis pada menit ke-120. Kegagalan ini menyebabkan suhu internal melonjak hingga 31,04°C karena pembuangan panas sisi panas yang tidak memadai dan aliran balik termal. Pada akhirnya, konfigurasi TEC lapisan tunggal sangat direkomendasikan untuk aplikasi pendinginan jangka panjang yang stabil, sedangkan desain lapisan ganda di masa mendatang memerlukan peningkatan signifikan dalam kapasitas pembuangan panas, seperti penggunaan sistem pendingin cair atau heatsink dengan konduktivitas termal tinggi. ======================================================================================================================================
This study investigates the performance of a portable 66-liter cooling box utilizing ThermoelectricCooler (TEC) modules (TEC-12715). The experimental design evaluates two primary configurations: a single-layer arrangement utilizing 14 TEC modules and a double-layer arrangement utilizing 10 TEC modules, tested under both no-load and full-load conditions over a 120-minute duration. Performance metrics, including temperature reduction and Coefficient of Performance (COP), were comprehensively analyzed. The results indicate that the single-layer configuration provides superior thermal stability. Under no-load conditions, it achieved a minimum internal temperature of -3.74°C with an average COP of 10.44, while under full-load, it maintained -2.94°C with an average COP of 10.39 without experiencing thermal failure. Conversely, the double-layer configuration demonstrated faster initial cooling but suffered from severe thermal instability during long-term operation. Under full-load, it reached an optimal -1.47°C at 95 minutes with an average COP of 1.49, before experiencing a critical thermal runaway by the 120-minute mark. This failure caused the internal temperature to spike to 31.04°C due to inadequate hot-side heat dissipation and thermal backflow. Ultimately, the single-layer TEC configuration is highly recommended for stable, long- term cooling applications, whereas future double-layer designs require significant improvements in heat dissipation capacities, such as utilizing a liquid cooling system or high-thermal-conductivity heatsinks.
