Turned LED heat sink. Do you know what material is better

For everyone who needs to turn LED heat sink, what you need to know is that copper has a high thermal conductivity, but loses heat more slowly. Aluminum has lower thermal conductivity than copper. But it dissipates heat faster. Steel doesn't do anything. Today, electronic radiator manufacturers will tell you why aluminum Turned LED heat sink will be better. The answer is as follows:

In theory, on the radiator, the copper base is in direct contact with the heating element, and then the radiator uses aluminum. This is good. In the same way, radiators made entirely of copper generally need to be equipped with fans. And the use of aluminum radiator generally do not need to install a fan (can also add a better effect).

Aluminum has several advantages over copper: light, cheap, easy to process, large specific heat capacity can absorb more heat, not easy oxidation and so on. So light is judged by its material. Plus your problem is not the radiator, but asked to do the heat sink (ordinary heat sink theory can be divided into two parts of the heat conduction substrate and heat sink). So the answer is aluminum is a better radiator.

You can look at mid to high end CPU radiators on a lot of computers. All are copper or heat pipe as heat conduction substrate. Aluminum for heat sink. This is a good combination in theory. See here I believe you have a clear understanding of the aluminum Turned LED heat sink.
