Abstract

Thermoelectric is a semi-conductor module that is commonly used in portable cooler box because it is light, saves electricity and does not require a large space. This thermoelectric based on cooling technology design is expected to provide data and analysis results that help cooler box designers to produce the best performance The purpose of this research is to study the effect of using thermal paste, environmental factors and heatsink. The results of the study show  that testing with thermal paste obtained the best conditions with the average temperature of the cold side being -1.17 oC with the best temperature being -6.05 oC. In the test conditions in the box if proven better than the open temperature conditions with a temperature difference of 7.4 oC. In the heatsink test, there was a decrease in performance caused by the influence of the conductivity of the heatsink material, which was 4.87o C.

Abstract

The electric vehicle (EV) industries have grown; in 2023 EV sales increased by more than 30% compared to 2022. The central issue of this industry is the battery because of the cost and environmental problems.  This makes efficient battery operation and condition imperative. The electric vehicle lithium-ion batteries are highly temperature-dependent for optimal performance and longevity. A cooling system is needed to maintain the temperature of the lithium-ion battery within the optimal temperature range. This study proposes nanofluid cooling based on Cellulose Nanocrystals (CNC) inside the wavy channel tube. Other fluid cooling, such as air and water, are compared. Three-dimensional (3D) transient simulation is performed by varying the cooling fluid and mass flow rate. On the other hand, experiments were conducted to validate the simulation's conformity to the battery module's temperature. The performance of the cooling fluid inside the wavy channel effectively keeps the battery heat dissipation and temperature uniformity. The nanofluid can maintain the temperature of the battery module at its optimal temperature (below 40°C), even with the lowest flow rate (5×10-4 kg/s).
