The thermal conductivity or heat transfer rate of copper is 92% versus aluminum which is approximately 49%. However, the copper fin bonded to the tubes, or water passages, using lead solder is very inefficient and slows the heat transfer rate to just slightly better than that of aluminum.
1 Copper has a better heat transfer rate than an aluminum coil Repair Ease 2 A copper tube is easily repaired in the field when damaged whereas an aluminum coil, when damaged, typically requires an entire coil
Copper vs. Aluminum - Thermal Conductivity & Radiation Jan 28, 2009 · Copper is better at heat transfer and aluminum is better at heat dissipation, so good heatsinks have a copper base that quickly/efficeintly gets the heat away from whatever is being cooled, heatpipes that quickly take the heat away from the base, and the heatpipes are attatched to aluminum fins that quickly dissipate heat.
Copper is better at heat transfer and aluminum is better at heat dissipation, so good heat-sinks have a copper base that quickly/efficiently gets the heat away from whatever is being cooled,
Copper vs. Aluminum Heatsinks:What You Need to KnowElectronic devices can generate a lot of heat. So, heatsinks play an important role in helping to cool them. You may be aware that aluminum is the most popular metal for heatsinks, but that copper is also sometimes used. You may also realize that copper has better heat conductivity. So its natural to wonder, If copper has better heat conductivity, why is aluminum
