“…This requires a classification of the car cabin into different volumes is necessary since each body part has a different temperature sensation. The temperature distribution and heat flows in the car cabin can be investigated in detail with CFD, but the modelling effort is very high and the simulation speed for fast predictions is too slow [5] [6]. As a compromise between computation time and accuracy, a 5-zone model was chosen.…”

Abstract. This paper presents a 5-zone-car-cabin model which is able to simulate the car cabin's thermal condition depending on several influencing parameters. This includes the solar radiation, to which special attention is paid in this paper. In addition, a generic methodology for parameter optimization considering measurements on a reference vehicle is presented. Thus, a very high degree of determination of the model was achieved. This paper is motivated by the impact of auxiliary loads on overall energy consumption in battery electric vehicles. The further use of the model is intended to calculate the energy saving potentials of the heating, ventilation, and air conditioning system by reducing or increasing the target interior temperature. This is necessary for a predictive control of secondary consumers. IntroductionMost of the potential car buyers do not trust in the vehicle range of battery electric vehicles (BEVs), as they are often smaller than the manufacturer indicates. In addition, the so-called range anxiety (The fear that a vehicle cannot reach its destination because of insufficient range.) is still widespread. In order to counteract the range disadvantage, an efficient use of the available energy is necessary. This requires the knowledge of the overall energy requirement to cover the present route. Each route has different energy loads in terms of propulsion and secondary consumers. The heating, ventilation, and air-conditioning (HVAC) system can be the largest auxiliary load. It is shown that the range of electric vehicles significantly reduces when the HVAC system is activated [1], [2]. Depending on the weather conditions, up to 25% of the required energy is used by secondary consumers [3]. Thus, the HVAC system offers a considerable energy saving potential by reducing or increasing the target interior temperature in case of a predictive control. However, possible energy savings quickly lead to the conflict with passenger's comfort. To identify the energy saving potentials of an HVAC system, some preparation steps are necessary, according to figure 1.

“…With the development of 3D numerical computation and simulation, it has gradually replaced the earlier experiential design methods of engine cooling systems, promoting the accuracy of matching cooling air flow rates with radiator heat dissipation capacity, as well as solving systematical problems of overcooling or overheating [164]. Every approach has its own merits and demerits [165,166]. The 3D simulation approach simulates the distribution of temperature, velocity and pressure field and it also facilitates the structuration design and optimization, but 3D simulation actually has difficulties in describing the relevance between multi-thermodynamic cycle systems, which can be easily realized by the 1D approach.…”

“…Considering a real module simulation, such as the engine, pipes, bumper, crossbars, shroud, fan, battery, etc., which interact with the airflow field and might result in flow separation, cross flows, increased mixture, recirculation and pressure drop, etc., the 1D and 3D co-simulation is an approach that can integrate the advantages of the two simulation approaches while simultaneously eliminating the drawbacks [165][166][167][168][169].…”

Abstract:With the increasing demands for vehicle dynamic performance, economy, safety and comfort, and with ever stricter laws concerning energy conservation and emissions, vehicle power systems are becoming much more complex. To pursue high efficiency and light weight in automobile design, the power system and its vehicle integrated thermal management (VITM) system have attracted widespread attention as the major components of modern vehicle technology. Regarding the internal combustion engine vehicle (ICEV), its integrated thermal management (ITM) mainly contains internal combustion engine (ICE) cooling, turbo-charged cooling, exhaust gas recirculation (EGR) cooling, lubrication cooling and air conditioning (AC) or heat pump (HP). As for electric vehicles (EVs), the ITM mainly includes battery cooling/preheating, electric machines (EM) cooling and AC or HP. With the rational effective and comprehensive control over the mentioned dynamic devices and thermal components, the modern VITM can realize collaborative optimization of multiple thermodynamic processes from the aspect of system integration. Furthermore, the computer-aided calculation and numerical simulation have been the significant design methods, especially for complex VITM. The 1D programming can correlate multi-thermal components and the 3D simulating can develop structuralized and modularized design. Additionally, co-simulations can virtualize simulation of various thermo-hydraulic behaviors under the vehicle transient operational conditions. This article reviews relevant researching work and current advances in the ever broadening field of modern vehicle thermal management (VTM). Based on the systematic summaries of the design methods and applications of ITM, future tasks and proposals are presented. This article aims to promote innovation of ITM, strengthen the precise control and the performance predictable ability, furthermore, to enhance the level of research and development (R&D).

“…It found that the performing of the generator mostly depends on the heat transfer through the modules and especially on the thermal contact resistance. Pang et al (2012) investigated the cooling system of an internal combustion engine by coupling one-dimensional and three-dimensional simulations. The results of the study showed that the thermal performance of the radiator played a critical role in cooling system performance.…”

In the present experimental investigation, ethylene glycol cooling in a plate-fin heat sink was attached inside an aluminum cooling block for the cooling unit of a thermoelectric (TE) power generator system. The plate-fin heat sink with two different fin heights was made from aluminum with length, width and base thickness of 300, 200, and 25 mm, respectively. The ethylene glycol was used as a coolant. The effects of fin height, coolant volume flow rate, and hot side surface temperature were considered for the temperature differences between the hot side surface and cold side surface of the TE power module. The ethylene glycol cooling of the rectangular plate-fin heat sink inside the aluminum cooling block was compared to water and air cooling. The plate-fin heat sink for ethylene glycol cooling showed a significant effect on the cold side surface of the TE power module for cooling of the TE power generator system. The experiments were performed under conditions of the heat input to the hot side surface area within 60 min after steady state, for which the volumetric flow rates were 0.005, 0.010 and 0.015 m 3 /min. The results indicated heat transfer rate increase with increasing coolant volume flow rate and higher fin. When compared to the water and air cooling methods, the plate-fin is attached inside the aluminum cooling block gives the highest efficiency. The results of this study could be used for guidance that will enable the design of a cooling system with improved heat transfer performance in a TE power generator system.
