Description

Technical Field

[0001] The utility model relates to the technical field of transformer core production, in particular to a temperature reduction device for core production. Background Technique

[0002] The structural design of the amorphous three-dimensional wound core is innovative and efficient. Its core structure is mainly made of amorphous alloy strips through a winding process to form a unique three-dimensional wound structure. This structure not only has no joints, but also has a balanced three-phase magnetic circuit, which helps to achieve efficient electromagnetic conversion.

[0003] During its production process, an annealing furnace needs to be used to heat-treat the wound core to improve its physical and mechanical properties. However, after annealing, the core needs to be taken out of the annealing furnace and cooled. But after being taken out of the annealing furnace, the core still has a high temperature and needs to be placed outside the annealing furnace for further cooling. The traditional cooling method simply uses fans on both sides of the core to blow air for cooling. However, such a cooling method can only blow air for cooling through both sides of the core, and this cooling method has low efficiency and needs to be further adjusted. Summary of the Invention

[0026] Please refer to Figures 1-4 A cooling device for iron core production shown in the figure, which includes a side cooling device 1 and a bottom cooling device 2. The side cooling device 1 is arranged on one side of the bottom cooling device 2. The bottom cooling device 2 includes a bottom box 201, a group of symmetrically arranged air outlet pipes 202 on the left and right, a first air outlet hole 203, a second air outlet hole 204, and a first through hole 205. A group of air outlet pipes 202 are arranged at the bottom of the bottom box 201. The first air outlet hole 203 is arranged in the upper middle part of the air outlet pipe 202. There are multiple second air outlet holes 204, which are evenly arranged on both sides of the first air outlet hole 203 respectively. The first through hole 205 is arranged on the end face of the bottom box 201, and there are multiple first through holes 205 arranged in a matrix on the upper end face of the bottom box 201. A sliding groove 206 is also arranged on the upper end face of the bottom box 201. An adjusting plate 207 that can slide in the sliding groove 206 is arranged in the sliding groove 206. A second through hole 208 is arranged on the adjusting plate 207. There are multiple bottom cooling devices 2, and the air outlet pipes 202 arranged on each bottom cooling device 2 are connected, and a valve 209 is arranged at the connection place. A cylindrical guide pair 210 is also arranged on multiple bottom boxes 201. The cylindrical guide pair 210 is fixedly arranged on the upper part of the bottom box 201. A supporting net 211 for placing the iron core is arranged on the slider of the cylindrical guide pair 210;

[0027] The side cooling device 1 includes a fan frame 101 and a cooling fan group 102. The fan frame 101 is arranged on the bottom box 201, and there is at least one cooling fan group 102 and it is arranged on the fan frame 101 in an array arrangement. A group of symmetrically arranged fans 103 on the upper and lower sides are arranged on the cooling fan group 102.

[0028] Specifically, the first through hole 205 and the second through hole 208 have the same size, and the distance between two second through holes 208 is greater than the outer diameter of the first through hole 205.

[0029] Specifically, the air outlet pipe 202 at the outermost end after multiple bottom cooling devices 2 are connected is also connected to a blower 3.

[0030] Specifically, the second air outlet hole 204 is inclined.

[0031] Specifically, after multiple bottom cooling devices 2 are connected, the end far away from the blower 3 is sealed.

[0032] Specifically, a handle 4 for convenient pulling is provided on the supporting net 211.

[0033] Working principle: When blowing and cooling the iron core, the staff places the iron core on the supporting net 211 of the bottom cooling device 2, and then starts the equipment. The blower 3 extracts the room-temperature air and sends it into the two air outlet pipes 202, and blows it out from the first air outlet holes 203 and the second air outlet holes 204 designed on the air outlet pipes 202 and blows air onto the iron core placed on the supporting net 211 for cooling. In actual production, sometimes it is necessary to adjust the blowing air volume of the bottom cooling device 2 for the iron core. At this time, the position of the adjusting plate 207 can be adjusted by pulling. Since the distance between the second through holes 208 provided on the adjusting plate 207 is greater than the outer diameter of the first through hole 205, the position of the adjusting plate 207 can be adjusted by pulling and the first through hole 205 can be completely or partially covered, so as to achieve the purpose of adjusting the air outlet volume. When it is necessary to cool the iron core with the highest efficiency, the first through hole 205 and the second through hole 208 can be made to coincide by pulling the adjusting plate 207. At the same time, the electric control of the cooling fan group 102 provided on the side cooling device 1 is controlled separately and is not set in a series mode, so that the required cooling fan group 102 can be selectively turned on or off. If only one bottom cooling device 2 or a part of the bottom cooling devices 2 needs to be used, only the corresponding valve 209 needs to be closed.
