Liquid cooling systems use a liquid coolant, typically water or a specialized coolant fluid, to absorb and dissipate heat from the energy storage components. The coolant circulates through the system, absorbing heat from the batteries and other components before being cooled down in a heat exchanger and recirculated. This process is highly ...
Coolant is the most critical part of immersion liquid cooling technology. The selection of coolant should consider the following factors: Firstly, the coolant is in direct contact with the battery, and the risk of thermal runaway due to internal short circuits is significantly increased.
A non-conductive, i.e., low dielectric constant coolant, should ensure safety when operating the cooling system. Secondly, for the same reason to ensure safety, the ideal coolant should have a high flash point and be incombustible to avoid solidification or combustion in the use temperature range.
3. The coolant's viscosity and mass flow rate determine the power consumption to deliver the coolant. Since the viscosity of mineral oil is the largest, the power consumption under the same conditions is also the largest.
The average temperature change of the battery at a 3-C discharge rate, using different coolants: (a) pentaerythritol esters; (b) mineral oil; (c) No.10 transformer oil.
4. The comparative analysis of the three coolants shows that the pentaerythritol esters proposed in this study have certain advantages as a coolant for BICS, both in terms of cooling effect and power consumption.
The most typical coolants used for immersion thermal management systems can be divided into five categories: hydrofluoroethers, mineral oils (MOs), esters, silicone oils, and water-based. Hydrofluoroether was first used for immersion cooling of power electronics and has recently opened its way to the electric vehicle market.
