This technology utilizes a tandem-type oscillating heat pipe channel structure that positions the refrigerant evaporation zone at the center of the battery cell and condensation zones at both edges, effectively eliminating localized hotspots and optimizing heat transfer efficiency from the center to the periphery.
Existing cooling methods have faced challenges such as the risk of thermal runaway during high-temperature operation of lithium-ion batteries, performance degradation due to localized hotspots, structural complexity, and low heat transfer efficiency.
This technology features a pair of tandem channels (first and second channels) symmetrical about the center line within the cooling plate. By designing the central area facing the battery as the evaporation zone and the peripheral area as the condensation zone, the refrigerant circulates through a closed loop driven by vaporization-expansion pressure differentials, providing a practical solution for next-generation battery thermal management and safety systems.
