Aimed at the problems of uneven flow distribution, excessive flow resistance, difficulty in balancing heatdissipation and pressure drop in the bottom liquid cooling plate for energy storage battery packs, as well as heat accumulation under high-temperature operating conditions. A novel liquid cooling plate with symmetric diamond-meshchannels was innovatively designed, and a pre-cooling strategy was proposed for intermittent discharge under hightemperature environments. The flow and heat transfer performances of the novel liquid cooling plate were comparedwith those of the parallel-channel liquid cooling plate, symmetric serpentine-channel liquid cooling plate and commercial liquid cooling plate. The results showed that under the same boundary conditions, the lowest battery packtemperature was obtained by using the symmetric diamond-mesh channel liquid cooling plate, and the system pressure drop was reduced by 24. 40%, 44. 41% and 63. 93% respectively compared with the other three structures.The influences of coolant inlet flow rate, inlet temperature and channel height on cooling performance and systempower consumption were further analyzed. On the basis of the balance between heat dissipation effect and pressuredrop, the optimal inlet flow rate of 7. 5 L / min and the channel height of 4 mm were determined. In the 40 ℃ hightemperature environment, the maximum temperature of the battery pack was kept within the suitable working rangeunder different coolant inlet temperatures. When the coolant inlet temperature was increased by 10 ℃ , the maximum temperature of the battery pack was increased by 7. 5 ℃ . Under the intermittent discharge condition in hightemperature environment, the maximum temperature of the battery pack was controlled at 39. 97 ℃ throughout thewhole process with the pre-cooling strategy applied, which met the requirements for safe operation.Keywords: liquid cooling plate; structural design; battery for energy storage; thermal management; heat dissipation
