Product types and performance indicators of radiators

thermal performance 

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 heat dissipation area of the outer wall (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 coating the outer surface with a high radiation coefficient), and reducing the contact thermal resistance between different parts of the radiator (such as the steel pipe and string of a steel string radiator).

Economic indicators

The lower the unit heat dissipation cost (yuan/W) of the radiator, the lower the installation cost, the longer the service life, and the better its economy. The higher the metal thermal strength (unit mass of metal, heat dissipation per 1 ℃ temperature difference (in W/(kg ·℃)) of the same material radiator, the better its economy.

Requirements for installation, usage, and manufacturing processes

The radiator should have a certain mechanical strength and pressure bearing capacity, and should be easy to install and assemble into the required heat dissipation area; The size should be smaller, occupying less room area and space; Not easily damaged during installation and use; The manufacturing process is simple and suitable for mass production.

Requirements for hygiene and aesthetics

The surface of the radiator should be smooth and easy to remove dust; The appearance should be beautiful and coordinated with the room decoration.
