There are four thermal management solutions for global energy storage systems: air cooling, liquid cooling, heat pipe cooling, and phase change cooling. At present, only air cooling and liquid cooling have entered large-scale applications, and heat pipe cooling and phase change cooling are still in the laboratory stage.

1. Introduction There are various types of renewable energy, 1,2 among which electricity is considered the best energy source due to its ideal energy provision. 3,4 With the development of electric vehicles (EVs), developing a useful and suitable battery is key to the success of EVs. 5–7 The research on power batteries includes various types
Evaporative cooling modes can generally be divided into direct evaporative cooling (DEC) and indirect evaporative cooling (IEC) modes according to whether the air treatment is in contact with the water or not, as shown in Fig. 1.The performance of DEC is greatly affected by the outdoor climate conditions, the moisture content of the output air,

The strategies of temperature control for BTMS include active cooling with air cooling, liquid cooling and thermoelectric cooling; passive cooling with a phase-change material (PCM); and hybrid cooling that combines active and passive cooling [7]. Studies of the BTMS involve battery modeling and the investigation of the cooling
In particular, air cooling is low cost and well integrated with electric vehicle air conditioning systems, while liquid cooling has better thermal conductivity and
In a study by Javani et al. [ 103 ], an exergy analysis of a coupled liquid-cooled and PCM cooling system demonstrated that increasing the PCM mass fraction from 65 % to 80 % elevated the Coefficient of Performance ( COP) and exergy efficiency from 2.78 to 2.85 and from 19.9 % to 21 %, respectively.
In this paper, a comparative analysis is conducted between air type and liquid type thermal management systems for a high-energy lithium-ion battery module. The parasitic power consumption and cooling performance of both thermal management systems are studied using computational fluid dynamics (CFD) simulations.
For liquid cooling and free cooling systems, climate conditions, cooling system structural design, coolant type, and flow rate are key factors in achieving thermal management and reducing
Liquid air energy storage (LAES): A review on technology state-of-the-art, integration pathways and future perspectives Compression heat can be used to satisfy external needs for heating and domestic hot water, while cooling demand can be met by either an additional absorption chiller [37, 54, 110] or, directly, from air
The air-cooling BTMS can be applied to electric vehicles with low energy density and low comfort requirements, such as vehicles with short operating hours. The liquid cooling BTMS is a promising cooling method, but it is very sensitive to the problem of liquid leakage. It needs high attention during design.
In the air cooling condition, the maximum cycle life difference rate ( ζN) is over 20% at a low Vin, e.g. 0.5 m s −1. With the increase of Vin, ζN is reduced. In PCM cooling condition, ζN is lower than 5% and the largest value is 4.1%, which has a strong link to the liquid phase fraction of PCM. 3.

Liquid cooling has larger convective heat transfer coefficient than air cooling, which can better control the temperature of electronic devices. However, as an active cooling technology, it is usually bulky, noisy, consumes extra pump power [ Citation 7, Citation 8 ], and it cannot cope well with short-time ultra-high thermal impulse.
It is important to consider these factors when choosing between air and liquid cooling systems. The choice of energy storage temperature control technology is the result of a comprehensive consideration of factors such as safety, economy, battery pack design, and the environment in which it is located, rather than a simple consideration of
A novel liquid CO 2 energy storage-based combined cooling, heating and power system was proposed in this study to resolve the large heat-transfer loss and system cost associated with indirect refrigeration and low cooling capacity without phase change for direct refrigeration. In the system proposed in this study, the cooling capacity
Abstract.

Air cooling and indirect liquid cooling considering water as a coolant [11] have been commercialized for BTMS.

The advantages of air cooling are simple structure and low cost, but the heat transfer coefficient and the cooling speed are slow. With the increase of battery density, air-cooling method gradually cannot meet the thermal safety demand of EVs [10, 11]. The cooling of PCM requires PCMs with high phase change potential and thermal

To maintain the indoor temperature of DCs or TBSs, the computer room air conditioning (CRAC) system and chilled-water system have been developed which are energy intensive (Borah et al., 2015) and contribute more carbon emissions.Energy-saving cooling technologies, as environmentally friendly and low-cost cooling solution, have
We hypothesized that directly cooling the CPUs with mineral oil would bring to near zero the ΔT between the heat source and the fluid in the discharge line. Based on this idea, we assembled an immersion system for our server blade as shown in Fig. 2.As Fig. 2 illustrates, our idea was to submerse a server blade up to the level of the CPUs in
The active cooling system such as liquid cooling consumes extra energy due to the additional water pump, shortening the total mileage of EVs or HEVs [135]. Park et al.
