    Abstract
    Alat penukar kalor (heat exchanger) pipa konsentris tiga saluran merupakan pengembangan atau perbaikan alat penukar kalor konsentris dua saluran. Penelitian ini dilakukan untuk mengetahui temperature keluaran masing-masing saluran, serta membandingkan hasil perhitungan secara teori menggunakan pemodelan matematika terhadap hasil eksperimen yang dilakukan dilapangan. Sehingga didapat perbedaan nilai antara hasil eksperimen terhadap hasil perhitungan teori. Pada penelitian ini memiliki 3 variasi data suhu yaitu sebesar 50°C, 55°C, dan 60°C dengan dua aliran yaitu CounterFlow dan PararellFLow dan debit 2,5 l/menit, sedangkan fluida dingin dengan 25°C debit 1,5 l/menit. Dari analisa diatas dapat disimpulkan temperature fluida panas keluar dari APK pada eksperimen cenderung lebih tinggi dibandingkan dengan temperatur fluida panas keluar dari APK pada perhitungan teoritis metode pemodelan matematika. Sementara itu temperatur fluida dingin dingin keluar dari APK pada eksperimental cenderung lebih rendah dibandingkan dengan temperatur fluida dingin keluar dari APK pada perhitungan teoritis metode pemodelan matematika.
     
    A three-channel concentric pipes heat exchanger is a development or improvement of a two-channel concentric heat exchange apparatus. This study was conducted to determine the output temperature of each channel, and compare the results of theoretical calculations using mathematical modeling of experimental results conducted in the field. So that obtained difference of value between result of experiment to result of theory calculation. In this study have 3 variations of temperature data that is 50 ° C, 55 ° C, and 60 ° C with two streams namely CounterFlow and PararellFLow and discharge 2.5 l/minute, while cold fluid with 25 ° C discharge 1.5 l/minute. From the above analysis it can be concluded that the temperature of the hot fluid coming out of the APK in the experiment tends to be higher than the temperature of the hot fluid coming out of the APK on theoretical calculations of mathematical modeling methods. Meanwhile, the cold cold fluid temperature coming out of the APK in experimental tends to be lower than the temperature of the cold fluid coming out of the APK on theoretical calculations of mathematical modeling methods.
