Graphical Processing Units (GPU) have become a vital source for data processing in many advanced or smart technologies. They have proven to be faster and more efficient than the Central Processing Unit (CPU) in computing large data sets. The automotive industry has adopted GPUs for Advanced Driver Assistance Systems (ADAS), but other systems like electric vehicles and autonomous vehicles will also employ GPUs soon. Although GPUs are faster at computing large data sets, there is the challenge of a substantial increase in core temperature during the process. This review paper primarily focuses on Active and Passive cooling methods for GPUs in automotive. The paper commences by addressing the role and need for GPUs in the automotive industry and explores the challenges faced by them and the factors that lead to an increase in temperature. The paper further reviews various cooling methods used by Original Equipment Manufacturers (OEM) in the automotive industry. The outcomes of the review are a detailed understanding of the use of GPUs in automotive, a brief interpretation of heating issues in GPUs and what causes them, a comprehensive understanding of the cooling methods used to reduce the core temperature, and a perception of an anticipated technology to resolve the heating problem.

“…As the technology matures and computer chips grow smaller in areas such as electronics, communications, aerospace, transportation, and manufacturing, the need for highperformance heat-transfer materials has arisen [1][2][3]. In many cases, higher performance means more heat, which becomes a limiting factor in electronics design.…”

Electronics depend on their ability to shed operational heat to maintain operating temperature. Inferior grease can create preventable problems in electronics. This is typically achieved through a thermal grease or paste. If this grease fails to dissipate heat or maintain thermal contact, then the equipment will have faults. Greases with less-than-optimal performance create excessive wear, heat, and reduced life expectancy. This can cause equipment failures and malfunctions at the most inopportune moments. Thermal greases are applied to Central Processors (CPU) and Graphics Processors (GPU) in avionics LRUs, computers, Solar panels, HVAC systems, and other electronics. A high-performance novel nano grease will shed excess heat and increase device life expectancy. The fabricated nano greases show improvements of up to 80% in thermal conductivity measurements. CPU testing resulted in a 100% decrease in the standard deviation of temperature variation from commercial greases.

“…One of the most common cooling methods for electric motor applications is the use of cooling jackets, in which a coolant absorbs the heat flux generated by the electric motor, avoiding the excessive rise in temperature [17][18][19][20]. Reducing the thermal capacity of the coolant fluid and increasing the speed of the coolant fluid are common methods for improving the heat transfer of a cooling system [21].…”

In this paper, the overall performance of an electric machine cooling system was examined in terms of heat transfer and fluid flow. The structure of the cooling system was based on the cooling jacket method. The cooling jacket contains spiral channels surrounding the stator and end-windings of the electric machine. Al2O3-water nanofluid is used inside the channels as the cooling fluid. The concentration of nanoparticles and the geometric structure of the cooling system have special effects on both aspects of heat transfer and fluid flow. Therefore, in this paper, the overall performance of the cooling system was evaluated by considering these effects. This study compared the importance of heat transfer and fluid flow performances on the overall performance of the cooling system. Numerical analyses were performed by 3D computational fluid dynamics and 3D fluid motion analysis. The analyses were carried out based on the 3D finite element method using the pressure-based solver of the Ansys Fluent software in steady mode.
