“…These air cooled heat exchangers are bulky and heavy, so they are not suited for mobile applications. Water cooled heat sinks have also been designed previously [6,7]. A circular tube with internal fins was selected by Riffat and Qiu [7], while Chein and Chen [6] designed a microchannel heat sink (hydraulic diameter of up to 150 m).…”

“…While the study by Jang et al (14) revealed that the impinging jet design of the microchannel heat sink enhances the heat dissipation capability by 48.5% compared to the conventional type; the reduction in pressure drop, 90.5%. Chein and Chen (15) used experimental and theoretical means for the study of the heat dissipation with coupling of thermoelectric cooler and microchannel as an aid; their results indicated that the thermal resistance determined by experiment is in agreement with that predicted by the theoretical model based on a lumped system. Besides, an increase in the current derived from the thermoelectric cooler decreases the thermal resistance.…”

This study investigated the behavior of pressure drops and heat transfer coefficients for four sets of triangular microchannels. Results of this study indicated that for Reynolds numbers less than 100, the Nusselt number tends to be nearly linearly increasing as the Reynolds number increases. The product of the friction factor and the Reynolds number (fRe) is slightly lower than those predicated by the conventional theory. Besides, high temperature gradient exists in the regions between the inlet and the exit of the flow channel. Furthermore, the difference between the values for Nu of those obtained from the empirical correlation for triangular microchannel and those from the experimental measurements was found to be within 15%.

“…Pemilihan sistem pendingin kompresi uap cocok untuk dikembangkan pada sespan berpendingin dengan kapasitas angkut yang besar, karena memiliki nilai COP yang tinggi. Sedangkan sistem pendingin pada alat transportasi ikan untuk pedagang ikan keliling dengan kapasitas kecil dapat menggunakan pendingin termoelektrik (Chein & Chen, 2005;Jugsujinda et al, 2010;Sutjahja, 2010;Zhou & Yu, 2011;dan Shen et al, 2012). Evaporator terbuat dari pipa alumunium diameter 6 mm kemudian dililitkan di bagian dalam dinding peti insulasi sedangkan kondensor (dibuat dari bahan sama dengan evaporator) dililitkan pada bagian luar peti insulasi.…”

ABSTRAKPenelitian untuk mendapatkan desain sespan berpendingin untuk pedagang ikan keliling telah dilakukan. Penelitian ini dilakukan untuk mendapatkan desain sespan berpendingin untuk pedagang ikan keliling, yang diharapkan dapat mempertahankan mutu ikan segar selama transportasi. Tahapan desain dilakukan dengan menentukan kriteria desain, penentuan konsep desain, analisis desain, pembuatan alat dan uji kinerja. Sespan berpendingin untuk pedagang ikan keliling terdiri dari peti insulasi, sistem pendingin dan penghubung peti ke sepeda motor. Uji kinerja dilakukan dengan mengamati suhu ruang peti dalam kondisi kosong, suhu ikan selama transportasi, penentuan nilai Coefficient of Performance (COP), serta pengamatan mutu ikan sebelum dan setelah transportasi. Hasil uji performansi alat dalam kondisi kosong selama 2,5 jam menunjukkan bahwa suhu ruang peti mencapai -17,6 °C. Sespan berpendingin dapat mempertahankan suhu ikan antara 1,0-2,4 °C selama transportasi. Nilai organoleptik ikan sebelum dan setelah transportasi adalah 7,13 dan 7,1. Sedangkan angka TPC ikan sebelum dan setelah transportasi adalah 1,6 x 10 3 dan 2,2 x 10 3 koloni/g. Nilai TPC dan organoleptik ikan setelah transportasi memenuhi standar mutu ikan segar, hal ini menunjukkan bahwa peti ikan segar berpendingin dapat mempertahankan mutu ikan segar selama proses penjualan ikan secara eceran. Nilai COP sespan berpendingin sebesar 0,44. KATA KUNCI:sespan berpendingin, COP, mutu ikan segar, pedagang ikan keliling ABSTRACT Research on refrigerated sidecar design for fish pitchman was conducted. The research aimed to maintain the quality of fresh fish during transportation. This study was carried out through
