An electronic radiator is a device that accelerates the heat dissipation of a heating element. There are two points to measure the quality of a radiator: heat dissipation and silence.
The quality of the material (purity, thickness, machining accuracy, etc.) and manufacturing process (cracks, shrinkage holes, etc. produced by casting), inferior materials and rough and defective processes will directly affect the thermal conductivity of the radiator.
The surface roughness and flatness of the radiator contacting the table surface directly affect the contact thermal resistance and pressure drop; the disc spring used for the radiator should ensure that the free height should be stable after being flattened for 24 hours, otherwise the spring may fail after a period of use. It will cause poor contact between the heat sink and the die.
When installing the radiator, a lot of pressure or torque is required. Since the diameter of the heat sink mesa is larger than the diameter of the die, the heat sink mesa will inevitably be deformed under the action of this pressure or torque. If a die with the same diameter or a larger diameter is mounted on the heat sink, the contact between the mesa and the surface of the die will be poor, and a good heat dissipation effect cannot be guaranteed. If the user needs to reuse the radiator, he must ensure that the surface roughness, parallelism and flatness of the radiator table meet the requirements, otherwise it is easy to damage the device due to overheating during operation.
Especially for water-cooled series radiators, before repeated use, be sure to check the deformation of the table carefully. If there is obvious sag, it should be replaced. In order to ensure good heat dissipation conditions for profile radiators and insert radiators, each die should have a corresponding radiator match.
