  A Parametric Study on a Thermoelectric-Integrated Battery Thermal Management System for Electric Vehicles: New Designs Utilizing Different Numbers of Thermoelectric Modules

  Tuğan, Volkan

  The safety, lifespan, and performance of battery systems in electric vehicles directly depend on the implementation of an effective thermal management strategy. In this study, a novel lithium-ion battery thermal management system integrated with a wavy cooling channel and different numbers of thermoelectric modules is proposed. Computational fluid dynamics-based numerical simulations were conducted at two ambient temperatures (298.15 K and 303.15 K) and three different thermoelectric temperatures (288.15 K, 293.15 K, and 298.15 K). Three configurations with four, six, and eight thermoelectric modules were analyzed and compared with the conventional case without thermoelectrics. The lowest maximum battery temperature was obtained with the design employing eight thermoelectric modules under the conditions of 298.15 K ambient temperature and 288.15 K thermoelectric temperature. It was found that integrating thermoelectrics into the battery thermal management system reduced the maximum battery temperature by up to 12.11 K and the maximum temperature difference by up to 5.83 K. Furthermore, maintaining the thermoelectric temperature approximately 5–10 K below the ambient temperature was identified as a critical design parameter to ensure both efficient cooling and thermal homogeneity. The use of different numbers of thermoelectric modules and the selection of appropriate operating temperatures were shown to play a decisive role in optimizing system performance.

  Effects of İnclined Plate in a Channel to Control Melting of PCM in a Body İnserted on the Bottom Wall

  Öztop, H.F.; Bakır, E.; Selimefendigil, F.; Gür, M.; Coşanay, H.

  A two-dimensional time-dependent computational analysis was carried out to examine the effects of inclined plate on melting time of Phase Change Material (PCM) filled square block on the bottom wall of a channel. Solution of the governing equations are performed by using finite volume method. The RT25HC material is chosen as PCM. The study is done for different parameters of inclination angle of the plate and Reynolds number. It is observed that the inclined plate can be used to control of melting time of PCM in a block as well as flow field and temperature distribution in the channel. Using of acceleration angle as θ = 110° accelerates the melting time of PCM inside the block. Thus, mass fraction rate increases 4 times with application of inclined thin plate.

  Heat transfer performance by forced convection of microencapsulated phase change material-latent functional thermal fluid flowing in a mini-channels heat sink

  Conventional single-phase coolants have not been able to meet the high cooling requirements of electronic devices. Microencapsulated phase change material-latent functional thermal fluid (MPCM-LFTF), a solid–liquid two-phase cooling medium, has the dual advantages of active liquid cooling and passive phase change material cooling. However, it also increases the power consumption in the mini-channels, and the cooling efficiency of MPCM-LFTF in practical applications needs to be further studied. A new MPCM-LFTF was prepared by paraffin melamine resin MPCM and base fluid (absolute ethanol and deionized water) in this work. The heat transfer performance and hydrodynamic properties were investigated using the dimensionless wall temperature and friction factor, respectively. The efficiency factor was introduced to evaluate the cooling efficiency of MPCM-LFTF in mini-channels. The experimental results showed that the addition of MPCM increased the viscosity of MPCM-LFTF, which increased the friction factor. MPCM-LFTF with a mass fraction of 15 % had the best effect of temperature control and reduced the dimensionless wall temperature by 40.5 %. However, considering the characteristics of flow resistance and improved heat transfer, MPCM-LFTF with a mass fraction of 10 % had the highest cooling efficiency and the efficiency factor was 57.0 % higher than that of the base fluid.
