Shorter cycle times, better product quality and less product outage can be possible with faster cooling. But mold cooling channels can only be made in linear directions and limited forms via classical manufacturing methods. Therefore, it limits that performance of mold cooling. Developed in recent years additive manufacturing technologies are capable of building complex geometries and monoblock 3D products. With this technology it is possible to produce metal molds with conformal cooling channels in different forms and capable of qualified cooling. In this study, conformal cooling channels were designed in order to achieve optimum cooling in monoblock permanent mold. In this study, CFD (Computational Fluid Dynamic) analyses are performed to steady stead conditions for designed conformal cooling channels and classical cooling channel mold. Pressure drops, cooling channel outlet temperatures and exergy destructions are calculated depending on the flow velocity rate in channels. The numerical investigations of the cooling process have shown that approximately 5% higher cooling performance can be achieved with conformal cooling channels. However, the pressure drop in the conformal cooling is observed to be higher than classical cooling channel. In addition, exergy destruction in the conformal cooling channel is approximately 12% greater than the classical cooling channel.

“…The cooling method of using phase change materials to achieve battery heat dissipation requires the installation of another cooling system to assist in heat dissipation, and the higher maintenance cost also limits its application in the battery thermal management system (Alipanah and Li, 2016;Li et al, 2018). Therefore, the liquid cooling method with higher heat dissipation efficiency and lower cost has more obvious advantages for battery module heat dissipation and can effectively prevent the overheating of lithium-ion battery under high discharge rate (Imran et al, 2018).…”

As a key component of a pure electric vehicle, the battery in an overheated state will have a direct impact on battery life and vehicle safety. To promote battery heat dissipation, a novel cobweb-like type (C-type) channel cooling plate with asymmetric inlet and outlet is designed. The C-type channel cooling plate is numerically simulated in two coolant flow directions (Ifd and IIfd), using the computational fluid dynamics software STAR-CCM+, and compared to the conventional serpentine type (S-type) channel. Meanwhile, the effects of three structural parameters (channel diameter, spacing, and cooling plate thickness) on maximum temperature and temperature difference of the C-type cooling plate, and pressure drop are investigated. Based on this, the C-type channel is optimized by orthogonal test. The results show that the C-type with IIfd coolant flow direction has a better heat dissipation effect on the battery module than the C-type with Ifd and S-type under the same conditions, and the maximum temperature and temperature difference are respectively reduced by 0.2% and 17.8%, while the pressure drop is increased by 17.3%. In addition, increasing channel diameter can obtain good battery temperature distribution and smaller pressure drop, while the increase of cooling plate thickness and channel spacing has a greater effect on the battery temperature difference compared to the change of maximum temperature. Finally, the results of the orthogonal tests show that the cooling effect is best when the diameter of the cobweb-like channel cooling plate is 7 mm, the thickness of the cooling plate is 12 mm, and the channel spacing is 16 mm, and the maximum temperature and temperature difference are reduced by 0.7% and 6.8%, respectively, and the pressure drop is reduced by 37.6% compared to the initial cobweb-like channel scheme. This offers a fresh perspective on cooling plate channel design in liquid-cooled battery thermal management.

“…By applying the nite element method, the cooling performance of mold cooling channels and the solidi cation process of liquid metal can be simulated. Numerical studies point out the possibility of an increase in the cooling performance with a decrease in the solidi cation time through the conformal cooling channel [10][11][12][13][14][15][16]. Conformal cooling channels for the plastic injection mold design and the numerical and experimental cooling performance were examined.…”

The cooling process in metal molds is one of the important factors in the solidi cation process of molten metal. Molding defects, such as hot spot defects and warping, are usually present in cast products when cooling is not uniform. However, quali ed and faster cooling positively a ects product quality. Molding is one of the important processes both in terms of cycle time and product quality, with permanent mold casting, high-quality liquid metal casting, and quality product. Selective Laser Melting (SLM) method was used to design metal mold cores with unique cooling channels to be compactly produced. The e ects of the designed cooling channels, heat transfer, and solidi cation of the molten metal are studied in transient numerical terms. The temperature distributions at the 1st, 3rd, and 5th seconds after casting were obtained, and the solidi cation processes were investigated according to the standard cooling channels of the original cooling channels. According to the results obtained, it was observed that solidi cation would function better in the originally designed cooling channels.
