The higher the heat transfer coefficient of the same material radiator, the better its thermal performance. Measures can be taken to improve the thermal performance of the radiator, such as increasing the outer wall heat dissipation area (adding wings (ribs)), increasing the flow velocity of the air around the radiator (such as adding a cover to a steel string radiator), strengthening the radiation intensity of the outer surface of the radiator (such as decorating the outer surface with a high radiation coefficient coating), and reducing the contact thermal resistance between different parts of the radiator (such as the steel pipe and string of a steel string radiator).
