The Leaf Vein series 5G base stations use multi-antenna technology to improve spectrum efficiency and meet the requirements of large-traffic network communication. One of the main design challenges of such devices is heat dissipation. This design is inspired by the veins of leaves, which are the main path for water vapor to be discharged from a plant. In this case, the 'veins' of the bionic leaves rapidly dissipate heat. A variety of designs (palmlike veins, parallel veins&straight veins) can be applied in scenarios such as tropical, temperate, and cold zones to meet the different requirements of power consumption.
