Compared with the cooling liquid on the side far from the spin sink, the temperature of the cooling liquid on the side close to the spin sink will rise rapidly. Since the inner wall of the cooling coil is smooth and has no corners, the position of the cooling liquid at different positions on the same section relative to the spin sink does not change greatly.

[0031] The outer wall surface of spiral coil 2 is fixedly connected with heat preservation layer 7, heat preservation layer 7 improves the heat preservation effect inside spiral coil 2, reduces the heat exchange of cooling liquid inside spiral coil 2 and external environment, reduces unnecessary loss, the upper end of spiral coil 2 is fixedly connected with water inlet pipe 5, the lower end of spiral coil 2 is fixedly connected with water outlet pipe 6, cooling liquid can enter the inside of spiral coil 2 through water inlet pipe 5, and finally is discharged through water outlet pipe 6.

[0032] Referring to Figures 2-4 The inner part of the spiral coil 2 is fixedly connected with a fixed sheet 3, the outer wall of the fixed sheet 3 is in close contact with the inner wall of the spiral coil 2, the side surface of the fixed sheet 3 close to the sink body 1 is in close contact with the outer wall of the sink body 1, the number of the fixed sheet 3 is several, and the several fixed sheets 3 are fixedly connected in the inner part of the spiral coil 2 along the spiral path of the spiral coil 2, which can continuously guide and disturb the cooling liquid and further improve the mixing effect between the cooling liquids at different positions. The outer side surface of the fixed sheet 3 is provided with a spiral groove 4, and the number of the spiral grooves 4 is several, and the several spiral grooves 4 are arranged in a staggered manner on the outer side surface of the fixed sheet 3.

[0033] When the cooling liquid reaches the fixed sheet 3, it will continue to flow after being divided by the several spiral grooves 4.

When the liquid passes through the fixed sheet 3, it will be divided into several streams by the several spiral grooves 4, and each stream can rotate and flow along the path of the spiral groove 4. When the several streams pass through the spiral groove 4 and intersect, they will mix with each other, so that the temperature of the cooling liquids at different positions on the same cross section in the inner part of the spiral coil 2 is kept balanced, the situation that the temperature of the cooling liquid close to the side of the sink body 1 is high is reduced, and the cooling effect of the sink body 1 is further improved.
