“…This may be because aluminium and its alloys are much more difficult to be processed by DMLS compared to stainless steels and commercially pure titanium and its alloys due to their poor flowability, high laser reflectivity and thermal conductivity and oxidation [18,19]. Only more recently, Ameli et al (2013) [20] used DMLS to produce the aluminium heat pipes with porous wick structures designed by repeating an octahedral unit cell. This work concentrated on the functional properties of heat pipes such as permeability, but did not evaluate the microstructure and mechanical properties of the as-made metal lattices.…”

“…Ameli et al [10] studied a possibility of using the Selective Laser Sintering/Melting (SLS/SLM) manufacturing process for the development of a sintered aluminium/ammonia heat pipe with a sintered wick structure. The application of the SLS/SLM processes helped manufacture very complicated wick structures with different thickness, porosity, permeability and pore sizes in different regions of a heat pipe.…”

“…Because of the complicated fabrication process and the use of copper as the wall and wick material, the cost of heat pipe limits its wide application in BTMS. Therefore, considering the aluminum heat pipe manufacturing and feasibility [33,34], the investigation on applying aluminum heat pipe in BTMS can be revealed as effective and reliable way to reduce the cost and weight of EV. In order to validate the use of UMHP in EV application, the thermal performance of UMHP BTMS by considering the influence of EV shock and vibration can be investigated in the future.…”

Due to the heat pipes' transient conduction, phase change and fluid dynamics during cooling/heating with high frequency charging/discharging of batteries, it is crucial to investigate in depth the experimental dynamic thermal characteristics in such complex heat transfer processes for more accurate thermal analysis and design of a BTMS. In this paper, the use of ultra-thin micro heat pipe (UMHP) for thermal management of a lithium-ion battery pack in EVs is explored by experiments to reveal the cooling/heating characteristics of the UMHP pack. The cooling performance is evaluated under different constant discharging and transient heat inputs conditions. And the heating efficiency is assessed under several sub-zero temperatures through heating films with/without UMHPs. Results show that the proposed UMHP BTMS with forced convection can keep the maximum temperature of the pack below 40 °C under 1 ~ 3C discharging, and effectively reduced the instant temperature increases and minimize the temperature fluctuation of the pack during transient federal urban driving schedule (FUDS) road conditions. Experimental data also indicate that heating films stuck on the fins of UMHPs brought about adequate high heating efficiency comparing with that stuck on the surface of cells under the same heating power, but has more convenient maintenance and less cost for the BTMS. The experimental dynamic temperature characteristics of UMHP which is found to be a high-efficient and lowenergy consumption cooling/heating method for BTMSs, can be performed to guide thermal analysis and optimization of heat pipe BTMSs.Keywords: Electric vehicle, Lithium-ion battery, Thermal management, Ultra-thin micro heat pipe © The Author(s) 2018.
