Ste eve cooler, in particular for blast furnace in metallurgy 10 is the metallurgical front (14) facing the inside of, the opposite back (16), having a top surface, opposite bottom surface and two sides, the panel body (12 and a). At least one internal cooling passage (36) is disposed in said L nyeolhyeong body 12. The panel-shaped body 12 is provided with a ledge (22) on its front (14); The ledge 22 extends between the side (10) to be arranged in a horizontal plane. At least one protection unit 100 is provided to cover at least a portion of the top surface 30 of the ledge 22. The protection section 100 includes a first side 110, second side 120 and the central portion (130); The first side 110 and second side 120 has a front portion 122 and a narrow connecting portion 124 is enlarged, respectively. The panel body (12) is provided in turn with each of the first side 110 and second side 120, and at least one through-arranged so that the center portion can obtain over 31. The invention also relates to a protection method of the ledge 22 of the stacking, such as Eve cooler 10.
