None.

Explanation:

A black dwarf is a white dwarf that has cooled to the point where it is emitting no significant tradition (heat or light). If we say that 5000K is cool enough then it will take about 10^15 years for a white dwarf to cool enough.

The universe has only been around for about 1.37*10^10 years. So no white dwarf has had enough time to cool enough.
