Kaji Sistem Peralatan Penyerap Kalor pada Kotak Penyimpan Darah
Abstract: This research aims
to produce an effective heat sink with thermoelectric which is a semi conductor
devices having several pairs of type P (positive) and N (negative) S content.
Type P has a lower energy level while type N had a higher energy level. This
tool, equipped with a heat sink as the heater, is mounted on a chamber to
create a heat exchanger for a portable cooler box. Three types of
thermoelectric modules were used with different fin types to find out the their
effects on the temperature, T, and the rate of heat transfer, Q, inside the
cooler box. The results shows that with the blood volume of 250 cc, the blood
temperature can be decreased from 29 oC to 5.8 oC within 145 minutes. The ideal
temperature for the blood storage ranges from 1 oC to 6 oC. Among the three
types of fins that were tested, the most effective heat transfer was given by
fin type no. 3, the cylindrical-shaped fins. The heat transfer obtained is
12.83 W/m2 oC. The lowest heat transfer was given by fin type no. 2, which is a
slot type, with heat transfer rate of 3.85 W/m2 oC.
