▎ 摘　　要

NOVELTY - The radiator has a radiating base (10) and multiple radiating columns (20). The radiating columns are distributed on an upper surface of a substrate (11) in an array. Each radiating column includes a cylinder housing (21), a graphene core portion (22) and a graphene structure (23). The cylinder housing is made of heat-dissipating metal material. A lower end of the cylinder housing is combined with an upper surface of the substrate through hot-press welding. The graphene core portion is formed in the cylinder housing. A lower end surface of the graphene core portion is attached to the upper surface of the substrate. The graphene structure is formed to cover an outer side of the cylinder housing. An upper end of the graphene structure is integrally connected with the upper end of the graphene core portion and completely covers the upper end surface of the cylinder housing. A lower end of the graphene structure is combined with the graphene coating (12). USE - Radiator formed by semi-solid die-casting. ADVANTAGE - The traditional method of die-casting integrated molding is replaced, which effectively simplifies the molding process and reduces the cost. The graphene coating, the graphene core portion and the graphene structure are set together to effectively improve the heat dissipation effect of the product, and the overall performance of the product is better, which is worthy of promotion. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the radiator formed by semi-solid die-casting. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the radiator formed by semi-solid die-casting.
