“…An important feature of the created material is a very slow degradation of its wicking functionality with time. The long-lasting wicking functionality along with a wide operational temperature range make the created texture suitable for a variety of practical applications, where the choice of materials is currently very limited, such as cooling high-heat flux electronics, thermal and fluid management in aerospace systems [5][6][7], cooling data centers [1,2], heat dissipation in power batteries and electronics of hybrid vehicles [15,110,111], and M-cycle applications, including air-conditioning [21][22][23][24][25], waste heat recovery [10][11][12], water desalination/purification [8,9,[112][113][114], and cooling towers [115]. Potential significant energy savings in air-conditioning of buildings [59] and cooling data centers [60] due to application of the material created here can contribute to mitigation of global warming.…”

“…Recent trends in cooling data centers [1,2], heat dissipation in high-heat flux electronics [3], cooling supercomputers [4], spacecraft thermal management [5][6][7], water desalination [8][9][10], waste heat recovery [11][12][13][14], cooling batteries [15], energy-harvesting [16][17][18][19], aircraft anti-icing [20], and Maisotsenko cycle (M-cycle) technologies [21][22][23][24][25] necessitate the creation of advanced capillary materials with efficient wicking/super-hydrophilic functionality at elevated temperatures. In particular, there is a fast-growing demand for these materials in cooling high-heat flux 5G electronics and in creating the next generation of M-cycle air-conditioning systems that will consume less electric power than the traditional compressor coolers by a factor of 5-8 [21,[26][27][28][29].…”

A superwicking Ti-6Al-4V alloy material with a hierarchical capillary surface structure was fabricated using femtosecond laser. The basic capillary surface structure is an array of micropillars/microholes. For enhancing its capillary action, the surface of the micropillars/microholes is additionally structured by regular fine microgrooves using a technique of laser-induced periodic surface structures (LIPSS), providing an extremely strong capillary action in a temperature range between 23 °C and 80 °C. Due to strong capillary action, a water drop quickly spreads in the wicking surface structure and forms a thin film over a large surface area, resulting in fast evaporation. The maximum water flow velocity after the acceleration stage is found to be 225–250 mm/s. In contrast to other metallic materials with surface capillarity produced by laser processing, the wicking performance of which quickly degrades with time, the wicking functionality of the material created here is long-lasting. Strong and long-lasting wicking properties make the created material suitable for a large variety of practical applications based on liquid-vapor phase change. Potential significant energy savings in air-conditioning and cooling data centers due to application of the material created here can contribute to mitigation of global warming.

As the increasing concern of degradation or thermal runaway of lithium-ion batteries, direct cooling system on electric vehicles draws much attention and has been broadly researched. Although satisfactory energy efficiency and thermal performance can be achieved according to current appliances, in-depth discussion of system design and modeling is still necessary for providing mature applications. Herein, a comprehensive review of direct cooling system is presented, and essential components on the overall design are introduced as 4C chain (construction of the system, component modeling, cooling plate design, and coolant selection). Construction, coolant, cooling plate, and component modeling are presented independently for discussing the research progress, where detailed information is provided contributing to the selection of essential components. Moreover, the typical applications on electric vehicles of direct cooling are also investigated, and more productions are under research.

“…The simplest method adopted consists in air cooling systems, both in natural and forced convection, often supported by heat sinks/pin-fins [6,7]. Liquid cooling strategies are more effective for EVs applications because of their high thermal capacity [8,9].

This paper presents an experimental evaluation of thermal and electrical performances of a 26650 cylindrical Lithium Iron Phosphate/graphite battery cell. Thermal management of Lithium batteries is a fundamental issue of electric mobility, where batteries are subjected to severe operating conditions. Therefore, battery heat generation is a very important characteristic to be studied. In this work cell performances were assessed during battery discharge at ambient temperature over a wide range of discharge rates. The cell surface temperature was measured both with thermocouples and infrared thermography. Furthermore, also the open circuit potential and entropic heat coefficient were experimentally measured. Based on this experimental data, a simplified battery thermal model was used to evaluate the battery heat generation. The results show a substantial increase of battery surface temperature especially at high discharge rates. During discharge, the heat generated is greater at low battery state of charge due to the sudden decrease of cell potential. The contributions to heat generation are also carefully evaluated.
