Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to a cooling device for enameled wire used in transformer production. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. During the transformer manufacturing process, the enameled wire of the transformer winding needs to be annealed to soften the enameled wire and facilitate subsequent painting and winding.

[0003] A search revealed a Chinese patent (application number "202020736188.7") disclosing "a cooling device for enameled wire in transformer production." This cooling device includes a base and a cooling box. The cooling box is located on top of the base and is slidably connected to the base. A bracket is welded to the top of the base, with its bottom located on top of the base. A fixed seat is welded to the top of the bracket, and a fan is attached to the top of the fixed seat. An air duct is located at the bottom of the bracket, with an air outlet plate at its bottom. A strip groove is located on the top of the base, and a rotary motor is located inside the base. A bent rod is located on the top of the rotary motor, with its bottom welded to the output shaft of the rotary motor. A sliding sleeve is located at the bend of the bent rod, and the sliding sleeve and the bent rod are rotatably connected. A connecting rod is located on one side of the sliding sleeve, with its top passing through the strip groove to the bottom of the cooling box. However, the above-mentioned cooling device has the following problems during use: 1. When drying the cooled enameled wire, the enameled wire in the coolant was not lifted, which caused the cold air to not come into full contact with the enameled wire, resulting in low drying efficiency. 2. After the enameled wire is cooled, the heat in the coolant cannot be dissipated, the coolant temperature rises, and the enameled wire cannot be cooled sufficiently, resulting in low practicality. Utility Model Content

[0004] This utility model provides a cooling device for enameled wire used in transformer production, which solves the problems of the prior art where the cooling device does not lift the enameled wire in the coolant, resulting in insufficient contact between the cold air and the enameled wire, low drying efficiency, inability to dissipate heat in the coolant, increased coolant temperature, and insufficient cooling of the enameled wire, thus reducing its practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cooling device for enameled wire used in transformer production includes a cooling cylinder and three support legs fixed to the outer wall of the bottom of the cooling cylinder. A stirring mechanism is located below the cooling cylinder. The stirring mechanism includes a first mounting plate fixed to the outer wall of the middle portion of the three support legs, a drive motor bolted to the outer wall of the bottom of the first mounting plate, a discharge pipe penetrating through and connected to the inner wall of the bottom of the cooling cylinder via a bearing, and an impeller connected to the outer wall of the upper portion of the discharge pipe via a pin. A lifting mechanism is located at the top of the cooling cylinder. The lifting mechanism includes two mounting blocks bolted to the outer wall of the upper portion of the cooling cylinder, and two bolts bolted to the bottom of the two mounting blocks. The cooling cylinder has a lifting cylinder on its outer wall and a cylinder cover bolted to the top of the piston rods of the two lifting cylinders. The cylinder cover is equipped with a lifting assembly, which includes a lifting cylinder bolted to the top outer wall of the cylinder cover and a storage basket with several through holes on the outer wall. A cooling fan is provided on the upper part of one side of the cooling cylinder, and a cooling mechanism is provided on the side of the cooling cylinder away from the cooling fan. The cooling mechanism includes a mounting box with an air inlet on one side of the outer wall, several heat-conducting blocks that penetrate and are fixed to the inner wall of the cooling cylinder, a second mounting plate bolted to the lower inner wall of the mounting box, and several heat dissipation plates fixed to the top outer wall of the second mounting plate.

[0006] Preferably, the upper part of the output shaft of the drive motor is connected to a drive gear via a spline, the lower part of the discharge pipe passes through and is connected to the outer wall of the first mounting plate via a bearing, and the upper outer wall of the discharge pipe has several discharge holes, the lower outer wall of the discharge pipe is connected to a driven gear via a pin, and the driven gear meshes with the drive gear to form a transmission engagement, and a sealing plug is inserted into the discharge pipe.

[0007] Preferably, two support plates are fixed on the lower outer wall of the cooling cylinder, and two lifting cylinders are respectively connected to the top outer wall of the two support plates by bolts. Four limiting rods are fixed on the bottom outer wall of the cylinder cover, and the four limiting rods pass through each other and slide on the outer wall of the two mounting blocks.

[0008] Preferably, a connecting plate is fixed to the bottom end of the piston rod of the lifting cylinder, and a connecting rod is fixed to the bottom of the connecting plate. The storage basket is bolted to the outer wall of the bottom end of the connecting rod.

[0009] Preferably, a fixing block is fixed on the upper outer wall of one side of the cooling cylinder, and the cooling fan is connected to the outer wall of the fixing block by bolts.

[0010] The above solution involves moving the storage basket and the enameled wire inside the basket by lifting the piston rod of the cylinder, so that the enameled wire is cooled in the coolant or above the coolant. The cooling fan operates to deliver outside air into the storage basket and dry the enameled wire. The existing technology enables the piston rods of the two lifting cylinders to rise synchronously, driving the cylinder cover and the storage basket to rise and separate from the cooling cylinder, thereby realizing the loading or unloading of the enameled wire.

[0011] Preferably, a connecting block is fixed on the outer wall of the cooling cylinder away from the heat dissipation fan, and the mounting box is bolted to the outer wall of the connecting block. An air outlet is opened on the outer wall of the mounting box. Several heat-conducting blocks are respectively inserted through and fixed on the inner wall of the mounting box, and several heat-conducting blocks are respectively fixed on the bottom outer wall of the second mounting plate.

[0012] The above scheme involves transferring heat from the coolant to one end of a heat-conducting block located inside the mounting box via multiple heat-conducting blocks. The second mounting plate exchanges heat with the multiple heat-conducting blocks, while the second mounting plate transfers heat to the heat sink. The cooling fan operates to deliver cool air from the outside into the mounting box, and the cool air from the outside transfers heat from the heat sink to the outside of the mounting box.

[0013] Preferably, the drive motor and the cooling fan are each connected to a switch via wires, and the two switches are each connected to a power supply line.

[0014] The beneficial effects of this utility model are as follows: 1. The piston rod of the lifting cylinder drives the storage basket and the enameled wire inside the basket to move, so that the enameled wire is in the coolant for cooling or above the coolant. The cooling fan runs to deliver outside air into the storage basket and air-dry the enameled wire. The existing technology enables the piston rods of the two lifting cylinders to rise synchronously, driving the cylinder cover and storage basket to rise and separate from the cooling cylinder, realizing the loading or unloading of enameled wire. The position of the enameled wire can be adjusted so that the enameled wire can fully contact the cold air, improving the air-drying efficiency.

[0015] 2. Multiple heat-conducting blocks transfer heat from the coolant to one end of the heat-conducting blocks located inside the mounting box. The second mounting plate exchanges heat with the multiple heat-conducting blocks. At the same time, the second mounting plate transfers heat to the heat dissipation plate. The cooling fan operates to deliver cool air from the outside into the mounting box. The cool air from the outside transfers heat from the heat dissipation plate to the outside of the mounting box. This can dissipate the heat in the coolant, prevent the coolant temperature from rising and slowing down the cooling speed of the enameled wire, and improve practicality.

[0016] In summary, this invention can adjust the position of the enameled wire, allowing it to fully contact the cold air, thus improving the drying efficiency. It can also dissipate heat from the coolant, preventing the coolant temperature from rising and slowing down the cooling speed of the enameled wire, thereby improving its practicality.

Multiple heat-conducting blocks 803 transfer heat from the coolant to one end of the heat-conducting block 803 located in the mounting box 802. The second mounting plate 804 exchanges heat with the multiple heat-conducting blocks 803, and at the same time, the second mounting plate 804 transfers heat to the heat sink 805. The outside cold air delivers the heat from the heat sink 805 to the outside of the mounting box 802.
