He has a conductivity coefficent K (W/mK) = .151 and air = .026. Since everything else in heat flux eq is linear, approximately 5x rate of heat movement per degree that the HD is heated beyond surrounding air is expected.
- tedunangst 8y agoYeah, I can read a table of figures too, but what does that mean in the context of a hard drive? What percentage of the heat generated by the write heads (or whatever) is conducted away via air?
- mattrices 8y agoThat is a function of the design implemented. Since you can read a table of figures you can probably also plug them in the heat flux equation in with your own guesses at air gap distances and surface area. The relevant info is that 5 times the energy per degree difference are conducted, that is why any hot spots from friction are smoothed.
