Abstract An electric motor, a battery and an inverter are the key components of any hybrid vehicle. The most commonly used switching device in the electric power conversion system is Insulated Gate Bipolar Transistor (IGBT) modules. Heat sinks with their fins are optimized to provide the maximum heat flow to the surrounding and Pure copper is used as it has high thermal conductivity with reasonable heat resistance. This helps to decrease the temperature of the IGBT and heat will spread to the fins. Parallel forced air cooling is utilised to give maximum possible heat removal rate. Further experimentation was done on a IGBT using an Inverter circuit and it was analyzed on ANSYS software and it was observed that the results obtained by numerical method and experimental method are approximately same.

The aim of the work is to choose a method of a solar car battery cooling. The student engineering team of Peter the Great Petersburg Polytechnic University designs the car. The analysis of the electrical circuit of the battery is carried out, the heat release is estimated due to three factors. According to the conditions of reliable operation of the battery, it is necessary to maintain its temperature range below 45°C, which requires cooling. The paper analyzes the possibilities of liquid, air-cooling, compares the free and forced methods of convective heat transfer. For the normal operating mode of the electric vehicle, environmental temperature at the level up to 38°C, a criterion thermal engineering calculation of the forced air-cooling of the corridor assembly of 405 battery cells providing the required heat dissipation is performed. It is shown that relatively high values of the heat transfer coefficient are provided under turbulent flow conditions characterized by Reynolds criteria above 103. On the basis of an analysis of the steady-state stationary heat-removal regime, it was concluded that an air flow provides a temperature gradient, sufficient for cooling the lithium-ion battery of a Solar Car «Polytech Solar».

According to the structural characteristics of the controller and micro-groove heat sink technique, a new cooling system was designed for high power control unit of electric vehicles. And an experimental comparison on the radiating effect of forced air cooling, micro capillary groove radiator and their combination was then carried out. The experimental results showed that when compared with air-cooling method, the higher the power is, the more significant the heat dissipation effect is. The air cooling unit alone cannot meet cooling requirements when the heating power reaches 30 watts, with temperature exceeding the allowable ceiling for power devices. The strong heat removal ability of micro capillary groove radiator has a better effect for diminishing local overheating of IGBT, and it’s more applicable to cooling conditions of large heat flux.

The present work compares the performance of various competing thermal management technologies for the desktop sector. An air-cooled heat sink used for the Intel Pentium 4 Processor is used as the baseline for comparison. Heat sinks based on metal foams, microchannels (with single-phase liquid) and jet impingement (with air and single-phase liquid) are compared based on total heat sink system thermal resistance and heat dissipation capacity. The analysis is carried out under the constraints of a fixed heat sink volume available in a typical desktop, and a fixed ambient air temperature. The comparison of thermal resistances is made under the constraint of the same pumping power as in the baseline heat sink. The maximum heat dissipation possible using a particular heat sink technology is estimated and this can be used to select technologies to meet future thermal challenges as outlined in the International Technology Roadmap for Semiconductors (ITRS). The results show that microchannel and liquid jet impingement cooling provide the greatest heat removal rates under the given constraints. The maximum power dissipation for these cases is almost double that of the baseline air-cooled heat sink. Under the chosen constant value of the junction to heat sink resistance, only modest improvements in heat removal rate are obtained with the microchannel and jet impingement technologies even if the pumping power constraint is relaxed, and a specific pump curve is used instead. The junction to heat sink resistance is significantly higher than the heat sink to ambient resistance, and is the key determinant in the comparisons.

As an effort in reducing the dependency on fossil fuel, efforts have been gathered to develop electric vehicle (EV) for the past decades. Technology of electric vehicles (EV) has been initialized in developed countries. However, the latter have different geographical and environmental conditions. Therefore, the system of EV cannot be utilized directly in this country. The controller of an EV functions by utilizing a potentiometer; supplying a certain amount of voltage from the batteries to the motor by driver’s force applied to the acceleration pedal. This action generates a huge amount of heat due to the internal resistance of the controller (e.g. potentiometer). In order for an EV to operate at optimum condition, temperature of the controller has to be maintained at a certain limit. Hence an effective cooling system is required to be designed to fulfill the above condition. The objective of this paper is to present the design of the cooling system for the controller of an electric vehicle (EV). Two types of cooling system namely liquid cooled plate heat exchanger and forced air cooled finned structure are designed and evaluated to assess the behavior of heat transfer as well as effects of heat transfer fluids and cooling system material towards the heat removal rate. Simulation using Computational Fluid Dynamics (CFD) for both cooling systems has been carried out to have better understanding. CFD results are compared with some of the analytical results. The findings revealed that both systems are suitable to be implemented as EV controller cooling system in Malaysian Environment.

Two Fluid

The flow and heat transfer characteristics in a forced-air cooled electronic device are calculated with a two-fluid model of turbulence. The fluids are defined as turbulent and nonturbulent, and precludes the need for low-Reynolds number model in the near-wall regions. Transport equations are solved for the zone-averaged variables of each fluid. Empirical relations, established in prior work, are used to express interchange of mass, momentum, and energy at the interface. Gradient-diffusion flux is considered an intrafluid source of turbulence. Several cases are considered showing effects of Reynolds number and heat-dissipation density on the flow and thermal fields. A critical comparison is made between the results based on the application of this model and the conventional k-ε model. Such results include velocity vectors and temperature distribution. In addition, the two-fluid model predicts spatial distribution of the intermittency factor, which provides a measure of the extent of turbulence and mixing in the electronic system.
