Heat dissipation design for lithium-ion batteries

Chen and Evans [8] investigated heat-transfer phenomena in lithium-polymer batteries for electric vehicles and found that air cooling was insufficient for heat dissipation from large-scale batteries due to the lower thermal conductivity of polymer as well as the larger relaxation time for heat conduction. Choi and Yao [2] pointed out that the temperature rise in …

How does an LED dissipate heat efficiently? : r/flashlight

Generally, heat is generated from the LED chip and is transferred through heat radiation, heat conduction, and heat convection. LED itself doesn''t have infrared and ultraviolet rays, so it has no radiation and heat dissipation function, mainly through conduction and convection. So LED flashlight should have a heat sink, which is the main medium for heat dissipation. After the …
