The invention discloses a stepped sharp-end hole radiator which is composed of a heat absorption face, a heat dissipation face center high-position radiator, distributed stepped sharp-end radiators and a heat dissipation face peripheral outmost side sharp-end radiator. Quick heat transfer is achieved by utilizing the stepped sharp ends, the amount of heat dissipation bodies is reduced and heat dissipation air flow rate is improved by utilizing distributed hole heat dissipation parts, the air flow heat dissipation speed is improved by utilizing the temperature difference of the stepped radiators, and the sharp-end hole heat dissipation parts are combined through pipe plates, plates and pipes. The stepped sharp-end hole radiator is suitable for heat dissipation of a solid heat source, a liquid heat source and a gaseous heat dissipation, is applied to the fields of electronic parts, power parts, aviation, aerospace, petroleum, chemical industry, environmental protection and treatment, energy saving, emission reduction and new energy utilization, achieves industrial, standard, universal and serial production of products, is simple in manufacturing process, does not produce pollutants in the production process and saves energy and reduces emission in the using process, and the products are repeatedly used in a full life cycle.
