Abstract

The current computational prediction investigated the effect of Non-Uniform Heat Flux (NUHF) patterns on Thermoelectric Generator (TEG) performance. It is studied the impact of changing resistance on the generated power under Uniform Heat Flux (UHF). The dissipated heat from the heat sink of electronic devices (e.g. CPU) through the TEG model, which was heated by NUHF and cooled by convection, was estimated. These devices tend to generate higher heat levels at their core, which gradually decreases toward the boundaries. In order to maintain an appropriate temperature for these electronic parts. A thermoelectric device, which includes a generator, is employed with a pin fin plate heat sink mounted on its back side to dissipate the heat. A numerical simulation was performed to determine the generated power and heat dissipation in the heat sink. When comparing UHF to NUHF, it is clear that the impact on generated electrical power is minimal and can be ignored. In addition, the findings showed that the difference between the NUHF and UHF is negligible and does not exceed 1%. The power generated in all cases is around 0.1 W and 4.6 W as a heat dissipation. It is found that the optimum load for the current suggested model is 3 Ohm. Also, there is a noticeable enhancement in the generated power by using the suggested heat sink reached up to 30% compared to the regular one.
