Does this model have any problems?

 

Uranus and Neptune have a similar internal structure.

However, inside temperature difference is very high.

Two planets big difference seems that they have different rotation direction to their moving direction.

This Figure is the internal structure of the two planets.

Interacting ice area is a special part of ice which is made at the ultra high pressure.

The contacting area is in the next picture.

Therefore we can imagine that the temperature difference between the two planet might be the result of interactions between Dark Matter and special ice solid.

This is the Uranus image. Why behind part is so bright?

To get the exact conclusion, I think, more research is needed.

More quantitative results are required.

Are there any other theory to explain the big difference of the generated heat flux of the two planets?

Not much is known about both Neptune and Uranus, really. Without a better detail of the two planets, no one is going to be sure of what the difference is, but to answer your question, there are plenty of possible reasons Neptune gives off more heat than it receives.

 

Decay of radioactives like potassium, it and/or it with its moon system may still be compressing under it's own gravity, or the high spin rate means that there is a fair amount of turbulence in its atmosphere, and the heating may just be due to turbulent viscous heating.

 

Plenty of ideas apart from your pet dark matter idea.
