Ceramic Heat Sink Vs Copper

Copper is better at heat transfer and aluminum is better at heat dissipation so good heat sinks have a copper.

Ceramic heat sink vs copper.

As you can see in this table copper is more conductive than aluminum. Copper is an excellent conductor of heat and radian uses cu1100 which has a thermal conductivity of 380w m k. Ceramic heat sinks for innovative thermal management.

They might look alike but they may have either a greater mass of aluminum a copper insert or more fins as well as possibly a fan with greater cfm s. This is because aluminum costs less than copper. The best practical coolers have a copper base usually heat pipes and aluminum fins. Despite the excellent thermal properties of a copper heatsinks aluminum heatsinks are typically used as they weigh approximately half as much as a copper conductor having the same conductivity and are also less expensive.

For more traditional uses the deep sink helps with large families and their consequent. The new ceramcool gu10 led spot works with any led. Aluminum alloys are the most common heat sink material. In fact aluminum only has 60 of the thermal conductivity that copper does.

Heat sinks are designed to maximize the surface area in contact with the coolant fluid. With a ceramic heat sink even if the driver fails completely mains electricity is not conducted by the heat sink and the product is safe. Some heat sinks use a combination aluminum fins with a copper base. That s one point for copper.

However copper is used where higher levels of thermal conductivity are needed.
