To maintain a machine running, a variety of fuels are required. Millions around the world have continued to work on the Internal Combustion (IC) engine, its processes, and its development despite the passage of time. In recent years, the main focus has been on improving fuel economy and lowering emissions. There is no alternative type that provides significant fuel economy or controlled emission perks, and none that compares to today's engines in terms of overall ease, protection, and adaptability, according to researchers. Thus, in this paper, we are discussing combustion engines, their types, and how they work, as well as the work done by a number of researchers to improve the efficiency of heat exchangers in combustion engines of various geometries.

“…When nanofluids were utilised, the heat dissipation rate of the finned heat sink rose, but the performance index of nanofluids was marginally lower when compared to base fluids [3,4]. Adeel Tariq et al looked at the thermal performance of a plate fin heat sink with holes and slots to see whether it may reduce pressure drop and heat sink weight [5]. Thermal performance was better for plate fin heat sinks with perforations and slots than for flat plate fin heat sinks [6].…”

The thermal performance of heat sinks with variable area straight fins with and without PCM is quantitatively explored in this article. The effects of diverse fin geometries (constant area straight fin, variable area straight fin, circular pin fin, hemispherical pin fin, and elliptical pin fin), varying Reynolds numbers, and fin densities on boosting electronics cooling performance were investigated. The goal of this research is to develop the best fin geometry for electronics cooling technologies. This research demonstrates that altering fin density can improve heat sink thermal performance while also reducing heat sink weight. The base temperature of the heat sink is found to be lower in variable area straight fins. In comparison to alternative configurations for heat transfer with PCM, the results show that variable area straight fin heat sinks are the most effective. The thermal resistance of the improved heat sink with variable fin density was reduced by 9%.

“…The results showed HTFF 158-2 that a straight minichannel heat sink (SMCHS) performed lower than the BWMCHSs in terms of thermal performance. Besides, four unique fins with holes and slots in rectangular and circular shapes using the conjugate heat transfer model were investigated experimentally and numerically by Tariq et al [7]. The results showed that the heat transfer coefficient of new plate-fin heat sinks is higher than that of plane fins without slots and holes.…”

In this paper, air-cooling models are investigated numerically on a new design of metal fin heat sinks based on the motor of the motorcycle using the Computational Fluid Dynamics (CFD) package ANSYS Fluent. The standard k -ε turbulence model was used in the numerical simulation. The domain was a rectangular geometry, and the metal fins created in the numerical model had three types: square pin, circle short pin, and circle long pin. These metal fin models were heated by a heat source at a power of 150-200 W based on the working range of the motorcycle's motor. Also, the air velocity for cooling was in the range of 40-60 km/h based on the motorcycle's speed. The temperature contours of the three models were used to compare the heat dissipation. The results showed that the thermal resistance did not change significantly when the heat source was changed. Notably, the circle long pin had the best effectiveness in dissipating heat compared to the others. The results from this research were important information that will help design and develop the heat sinks of the motor in the future.
