Does the protective cover of the data line affect the heat dissipation?

It has no effect on heat dissipation, and it does not have any benefit to the data line. It is just good looking, and it cannot prevent the data line from breaking. There is, heat dissipation, general data line, line body will not heat, will heat is generally the position of the plug at both ends. Especially the power adapter end, but the phone end is fine. So the kind of pretty stickers, stickers actually have an impact on the heat dissipation of the charger adapter, so it's best not to stick similar stickers.
