I dont know, but its not just the core, I go underground a lot of times during the year, and it can be 100 degrees outside but the underground is a cool 60, then in the winter it can be -20 outside, but the underground is a warm 50, and the only reason for the temprature change is becuase there are spaces that are open to the conditions.
my guess would be only the first few feet of ground change with the temprature, the rest is insulated
as for the core, possibly the pressure and gravity?
It bundles up?
Actually, I'm glad you asked, I'll have you know:
The heat of the Earth's core is a mixture of two sources. The first is the
initial heat from the formation of the planet. That is, as the smaller
bodies coalesced to form the Earth, their gravitational potential energy was
converted to a good deal of heat. The second source is the (continuing)
decay of radioactive elements in the bulk of the Earth (mantle as well as
the core). In spite of the latter, the planet has been slowly losing
net heat for quite some time. As this heat is lost, more and more of the
liquid outer core 'freezes' to enlarge the solid inner core.

They have a fireplace.
Or at least resoursefullness...
