Did a topic on thermodynamic so gladly moving onto that. I've given this some thought as well like the Zeta so good question.

The "Heat Vampire/Magnet" situation is actually how Killer Frost is typically portrayed.

With Cold Guns, propelling freezing agents (iquid helium perhaps, super fluid anyhow) which the beam contained in a "packet" until it makes contact, releasing contents to freeze into land ice bergs instananeously. This works particularly well with Captain Cold.

Freeze and Icicle Sr's cold weapons however, seem less discrete. With Freeze you can pretend he has enough liquid/gas to allow, but the flow rate's just too damn high for that to be feasibly. (this stuff aint that cheap). So to accomodate for production of material and solve the heat energy issue, I've assembles a sort of internal convection system. Two Tube Streams for their powers, the first is the fluid as it leaves the weapon, on the outside which we see. Then have heat energy and a fair bit of the used fluid converge to the centre, transporting latent heat with it, which then goes back in opposite direction to the beam. The Heat Energy which arrives back to the device is then used to power the production of the fluid itself. The elements are common, nitrogen, oxygen, helium, all very cold in liquid form and prevalent in atmosphere. The problem with producing is typically energy cost to power refrigeration devices (refirgerator is actually one of the pinnacles of "useful" thermodynamics, bit more complex then a kitchen fridge in this case though)

For Junior, his powers were inutero mutations due to his father's long exposure to his cold weapons. So i assume that a similar mechanism in used except internalise, also the ice being part of body composition, is able to use more generally, shaping near solid fluid to form weapons etc.
