The standard of the heat sink

Thermal performance of the heat sink
The higher the heat transfer coefficient of the radiator with the same material, the better its thermal performance. It can be used to increase the heat dissipation area of the outer wall (add wings (ribs), improve the flow speed of the air around the radiator (such as adding a cover to the steel cascade radiator), strengthen the radiation intensity of the outer surface of the radiator (such as the coating with high radiation coefficient on the outer surface) and reduce the space between various parts of the radiator (such as the steel pipe and cascade of the steel cascade radiator) The thermal performance of the radiator is improved by measures such as contact thermal resistance.

Economic indicators of the heat sink
The lower the cost per unit heat dissipation of the radiator (yuan / W), the lower the installation cost, the longer the service life, and the better its economy. The higher the metal heat intensity of the radiator of the same material (unit mass metal, heat dissipation per 1 ℃ heat transfer temperature difference (unit: w / (kg ·℃)), the better its economy.

Requirements for installation, use and process of the heat sink
The radiator shall have certain mechanical strength and pressure bearing capacity, and shall be easy to install and combine into the required heat dissipation area; The size shall be small and occupy less room area and space; It is not easy to be damaged during installation and use; The manufacturing process is simple and suitable for mass production.

Hygienic and aesthetic requirements of the heat sink
The surface of the radiator shall be smooth and easy to remove dust; The appearance shall be beautiful and coordinated with the room decoration.
