Hi 3DDave, the conclusion indicated in red in the attached article made me lean toward, that there might be substantial changes, but as you and georgeverghese suggested, I will be applying 0.7-0.8 to anodized aluminum surface at 20-120degC in the thermal simulation case. Will be testing the...
Can someone please share the info for Emissivity Coefficients of .050" Thk. black-anodized aluminum at a temperature range of 20 to 120 degrees C? I found the emissivity coefficient as 0.8 at the ambient temperature (20 degrees C), but I need to find the emissivity coefficient at 120 degrees C...
The emissivity coefficient of aluminum anodized is 0.77 as shown in the attachment. However, as applied the provided value to a thermal simulation case in SolidWorks, it seems 0.77 is way higher so that the simulated results for its surface temperature are very low compared to the real lab...
Hi 3DDave, thank you so much for the input. As suggested, I will add the simulation input conditions with Contact Resistances between the components and will monitor the simulation results accordingly compared with the actual thermal testing results in the lab. Thank you again for sharing the links.
Hi WKTaylor, Noted well NOTE1. Thanks. Regarding NOTE2, the purpose of anodization to this particular product is for thermal characteristics solely that reduce its surface touch temperature as run the thermal inputs in an ambient and thermal chamber. No functional or decorative but thermal...
Instead of dealing with the thermal conductivity value for AL5052 anodized, it might be more appropriate to adjust by defining thermal/contact resistance between the components. In this case, do you have some data in handy on the thermal/contact resistance value of the aluminum anodized material...
Hi 3DDave, thank you for the valuable input. As illustrated in the screenshot, the heat resource is to be conducted to the AL5052 anodized enclosure through Thermal Pad, and I need to simulate the outside touch temperature of the enclosure. It is one of the simulation scenarios in which the...
Thank you, WKTaylor. Refer to the JPEG files attached. To run a flow simulation with the SolidWorks Electronics Cooling for the simulation case as described in the attached, I need to know the value of the thermal conductivity that I can punch into the item properties of AL5052 anodized. The...
I have the part in my hand that is black-anodized, but I don't know what surface type of anodizing is applied. It seems to me the surface was treated with fine sandblasting (mild texturing) and then applied the black anodization on the entire surface. So, I don't know if it should be described...
The thermal conductivity of AL5052 and AL6061 is 138 and 167 W/(m*K) respectively. What would be the thermal conductivity for those materials as it black-anodized?
