Design of Portable Beverage Cooler Using One Stage Thermoelectric Cooler (TEC) Module

Abstract

The Portable Beverage Cooler (PBC) has been designed to satisfy the need of cooler apparatus that could be carried easily. The utilization of this apparatus was intended to minimize the environmental damage affected by vapour compression refrigeration system using CFCs Refrigerant. The peltier effect from thermoelectric module was utilized in this PBC and called as Thermoelectric Cooler (TEC). Furthermore, heat-sink and fan were needed to ensure the cooling effect continously worked. To achieved the objectives of this machine (portable, environment-friendly, low watt, affordable), the design consideration are heat load, insulating material, weight of components, electric consumption, and dimension of the cooling box. The results of the design shows the PBC cooling box dimension is 6 cm x 6.5 x 15 cm. The insulation of the PBC cooling box are polyurethane foam and polystyrene expanded with thickness 6 mm and 5.3 mm, respectively. The alumunium plate was applied as inner wall to enhance the cooling capacity of cooling room temperature. In this PBC was used one stage of TEC that could yield cooling room temperature until 15 oC in 30 minutes operation by consuming 20 W of electricity.

Experimental Performance of a Cooler Box with Heat Dissipation Unit Variations

“…The COP depended on the voltage input, but the COP was lower for an aluminum heat dissipation unit. Sujith et al [10] Aluminum tank filled with water 0.124 Kaushik et al [11] Not mentioned Not available Ahamat et al [12] Heat sink with water flow. 0.5-3.2 Pokale et al [13] Heat sink with a fan 0.03-0.19 Maral et al [14] An aluminum water block 0.26-1.2 Aziz et al [15] Heat sink with a fan Not available…”

“…P for the TEM is noted by PTEC, while P for the fan is written as Pfan, see Eq. (11). Then the performance of the cooler box can be expressed in the term of COP.…”

Kinerja Kotak Pendingin (Cooler Box) Berpendingin TEC1-12715 Pada Beberapa Beban Pendinginan

“…Kotak pendingin dengan menggunakan TEC sebagai sumber pendingin kotak sudah banyak dikaji, terutama dari tipe TEC1-12706. Kajian kinerja dari TEC1-12706 sebagai sumber pendingin kotak sudah dilaporkan, diantaranya oleh Gultom et al (2016), Aziz et al (2017), dan Mirmanto et al (2018). Akan tetapi sumber pendingin berbasis TEC1-12715 belum banyak dikaji kinerjanya dalam mendinginkan ruangan kotak pendingin.…”
