[0033] The water storage cavity 101 is filled with cooling water; a through hole 701 slidably matched with the outer tube 3 is arranged in the middle of the partition plate 7, the inner tube 2 penetrates the outer tube 3, a section of the inner tube 2 inside the water storage cavity 101 is a water inlet section, a section of the inner tube 2 inside the air drying cavity 102 is a water outlet section, a water inlet 201 communicating with the water storage cavity 101 is arranged at the top of the water inlet section, and a water outlet 202 communicating with the air drying cavity 102 is arranged at the bottom of the water outlet section; the liquid level of the cooling water is higher than the water inlet 201, and the outer tube 3 adjusts the position by sliding on the inner tube 2 to realize the adjustment of the opening degree of the water inlet 201. Thus, the conductor annealing cooling device of the embodiment of the present application can realize the covering adjustment of the outer tube 3 to the water inlet 201 by the sliding mechanism formed by the inner tube 2 and the outer tube 3, flexibly changes the opening degree of the water inlet 201, controls the usage amount of the cooling water into the inner tube 2, thereby effectively preventing the water carrying phenomenon caused by overcooling due to the fast speed when producing small wire gauge, and simultaneously, since a part (i.e. the water inlet section) of the inner tube 2 is located inside the water storage cavity 101 and the other part (i.e. the water outlet section) is located inside the air drying cavity 102, the effective cooling length of the conductor annealing is not limited to the range of the water storage cavity 101, especially when producing large wire gauge, the effective cooling length can be designed to be longer, the continuity of the whole cooling system is enhanced, and the surface oxidation or local oxidation problem caused by the high temperature of the conductor after passing through the cooling system when producing large wire gauge is effectively solved.
