1. A device for exchanging heat between an inside of a blast furnace and an outside of the blast furnace, comprising:

  • a body configured to be at least partially inserted into an opening in the blast furnace; and

    at least one cavity disposed within the body, each of the at least one cavities extending from substantially one end of the body to substantially an opposite end of the body, each of the at least one cavities capable of containing coolant;

    wherein the body is configured to transfer heat between a coolant contained within each of the at least one cavities and a heat sink outside of the blast furnace, and when the body is inserted into the opening of the blast furnace and each of the at least one cavities contains the coolant;

    the one end of the body is exposed to heat generated by the blast furnace and the opposite end of the body is exposed to the outside of the blast furnace;

    heat is absorbed by the coolant in a portion of the cavity in the vicinity of the one end of the body and is transferred to the coolant in a portion of the cavity in the vicinity of the opposite end of the body;

    the heat in the portion of the cavity in the vicinity of the opposite end of the body is transferred from the coolant, through the body, to the heat sink; and

    the body forms a barrier between the coolant and the heat sink such that substantially none of the coolant within each of the at least one cavities is in direct contact with the heat sink.
