Disclaimer: there is no publicly available testing data about the final phase of this encounter, so what follows is only what is theorized to be the case from the dungeon journal.
Throughout the fight, the tanks will swap in order to manage their Chilling Touch stacks. Jaina casts Ice Shard at her target, which applies one stack of Chilling Touch. Each phase has different ways of dropping your Chilling Touch stacks. You will not gain stacks in either intermission.
In Phase 1, you can drop your stacks using Searing Pitch. You will want to swap whenever a Searing Pitch is available to drop stacks on.
In Phase 2, you will drop your stacks using the barrels of Unexploded Ordnance (when they explode, they cast Burning Explosion). How often you detonate one of these will depend on your raid’s strategy, as everyone else is also dealing with the same debuff.
In Phase 3, you are no longer able to drop your stacks. This means you will need someone to break you out of your ice block when you reach 20 Chilling Touch. Additionally you will gain stacks faster from Jaina’s Prismatic Image. You will have to decide how and when to deliberately be frozen, and this will be dependent on your raid’s strategy.
Catweavable: In Phase 2.
