Conclusions The aluminum vapor chamber (Al-VC) utilizing phase-change heat transfer on the porous-coated surface was applied to the thermal management of the lithium-ion battery cell. The thermal performance of the Al-VC was systematically investigated to identify the effect of working fluid, cooling plate placement, and the filling ratio.
The connection between the heat pipe and the battery wall pays an important role in heat dissipation. Inserting the heat pipe in to an aluminum fin appears to be suitable for reducing the rise in temperature and maintaining a uniform temperature distribution on the surface of the battery. 1. Introduction
Although there have been several studies of the thermal behavior of lead-acid , , , lithium-ion , and lithium-polymer batteries , , , , heat dissipation designs are seldom mentioned.
Thus, the use of a heat pipe in lithium-ion batteries to improve heat dissipation represents an innovation. A two-dimensional transient thermal model has also been developed to predict the heat dissipation behavior of lithium-ion batteries. Finally, theoretical predictions obtained from this model are compared with experimental values. 2.
Consequently, temperature distribution and heat dissipation are important factors in the development of thermal management strategies for lithium-ion batteries.
Aluminum battery covers often incorporate fins, channels, or other heat-dissipating structures to enhance thermal management. These designs help regulate the temperature of the battery during operation, mitigating the risk of thermal runaway and improving overall efficiency.
