NOVELTY - A heat sink for charging pile, consists of base layer and coating. The coating is uniformly applied to upper surface of base layer. The coating is comprised with several inclined heat dissipation holes which are longitudinally opened in base layer. The coating is made of graphene solution comprising 10-20 pts. wt. graphene, 30-55 pts. wt. adhesive, 0.3-0.5 pt. wt. dispersing agent, 0.1-0.4 pt. wt. surfactant and 2-4 pts. wt. defoamer. USE - Heat sink for charging pile. ADVANTAGE - The heat sink has extremely high thermal conductivity, improved radiating speed and increased internal emission efficiency.
