The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0025] like Figures 1 to 7 As shown, the present invention provides an air-water cooling heat dissipation transformer for an offshore platform, comprising a shell 1, a transformer is arranged in the shell 1, a plurality of air passages 3 are arranged inside a coil 2 of the transformer, a backpack radiator and a water cooling component are fixedly mounted on the outer wall of the shell 1, the water cooling component is located below the backpack radiator, the top of the air passage 3 is connected to the backpack radiator, the air outlet end of the backpack radiator is connected to the bottom end of the air passage 3, the water cooling component is arranged at the air outlet end of the backpack radiator, and the water cooling component is used to cool the hot air flowing out of the air outlet end of the backpack radiator.

[0026] When the present invention is in use, the heat generated by the transformer during operation can heat the air in the air duct 3 arranged inside the coil 2. The hot air in the air duct 3 can be sucked away by the backpack radiator and enter the backpack radiator. Then, the hot air in the backpack radiator is cooled by the water cooling component below to form cold air, and re-enters the air duct 3 in the transformer from the bottom of the transformer to take away the heat of the transformer again. Such a cycle realizes the heat dissipation of the transformer.

[0027] The present invention adopts a closed circulating water circuit and air circulation passing through the inside of the transformer, which effectively solves the heat dissipation problem of the transformer. During the heat dissipation process, the transformer will not contact with the external ambient air, thereby solving the problem of salt mist corrosion to the transformer.

[0028] According to a further optimization scheme, in order to avoid the problem of local overheating of the coil 2, the air duct 3 is arranged in the vertical direction, and the air duct 3 is arranged inside the coil 2 at equal intervals in the circumferential direction.

[0029] A further optimization scheme is provided. In order to facilitate the use of the backpack radiator to discharge the hot air in the air duct 3, and at the same time to improve the heat dissipation effect of the backpack radiator, the backpack radiator includes a heat dissipation shell 4 fixedly mounted on the outer shell 1, and a fan is arranged inside the heat dissipation shell 4. A motor 5 for driving the fan to rotate is fixedly mounted on the outer wall of the heat dissipation shell 4. The air inlet end of the fan is connected to the top of the air duct 3 through a pipeline, and the air outlet end of the fan is arranged in the heat dissipation shell 4; the bottom of the heat dissipation shell 4 is fixedly connected to an air outlet pipe 6, and the end of the air outlet pipe 6 is connected to the bottom end of the air duct 3, and the water cooling component is arranged corresponding to the air outlet pipe 6.

[0030] A further optimized solution, in order to ensure the cooling effect of the hot air discharged from the backpack radiator, the water cooling assembly includes a cooling shell 7 fixedly mounted on the outer shell 1, a cooling water pipe 8 is arranged inside the cooling shell 7, and a plurality of cooling water tanks 9 are arranged in sequence on the cooling water pipe 8 along the flow direction of the cooling water, the air outlet pipe 6 passes through the plurality of cooling water tanks 9 in sequence, and the air flow direction in the air outlet pipe 6 is opposite to the cooling water connection direction in the cooling water pipe 8.

[0031] To further optimize the solution, in order to ensure sufficient contact between the cooling water and the air outlet pipe 6 , the cooling water tank 9 is arranged in the vertical direction, and multiple cooling water tanks 9 are arranged in sequence in the horizontal direction, and the water inlet end of the cooling water tank 9 is located at the bottom of the cooling water tank 9 .

[0032] To further optimize the solution, in order to facilitate the cleaning of the outer wall of the outlet pipe 6 in the cooling water tank 9, reduce the impact of scale on the outlet pipe 6, and ensure the heat exchange between the outlet pipe 6 and the cooling water, the cooling water tank 9 includes two correspondingly arranged box bodies 10, and an annular sealing groove 11 is opened on the opposite side of the two box bodies 10, and a sealing strip is arranged in the annular sealing groove 11; a connecting piece 12 for connecting the two box bodies 10 is fixedly installed on the outer wall of the box body 10.

[0033] To further optimize the solution, in order to increase the contact area with the cooling water, slow down the flow rate of the air flow, and improve the cooling effect of the cooling water, the air outlet pipe 6 is connected to a plurality of clustered pipe assemblies, and the clustered pipe assemblies are arranged in a one-to-one correspondence with the cooling water tank 9.

[0034] According to a further optimization scheme, the cluster tube assembly includes a plurality of micro tubes 13 , both ends of the micro tubes 13 are fixedly connected with a diverter plate 14 , the diverter plate 14 is connected with the air outlet pipe 6 , and the air outlet pipe 6 and the box body 10 are sealed by a sealing strip.

[0035] The air-water cooling heat dissipation transformer for offshore platforms provided by the present invention has the following working principles:

[0036] The heat generated by the transformer during operation is absorbed by the air in the air duct 3 in the coil 2, so that the air in the air duct 3 forms hot air and rises. At the same time, under the action of the fan, the hot air in the air duct 3 is pumped into the heat dissipation shell 4. Under the action of the hot air, the temperature of the heat dissipation shell 4 rises. Under the action of the external airflow, the heat dissipation shell 4 is cooled, thereby achieving a cooling effect on the hot air; the air in the heat dissipation shell 4 is discharged through the air outlet pipe 6 under the action of the fan, and when passing through the cluster pipe assembly on the air outlet pipe 6, it will exchange heat with the cooling water in the cooling water tank 9. Under the action of multiple cooling water tanks 9 and cluster pipe assemblies, the air temperature in the air outlet pipe 6 becomes lower and lower, and the temperature in the cooling water tank 9 becomes higher and higher. Through the circulation of cooling water, the cooling water after absorbing heat dissipates and cools on the outside of the cooling shell 7, thereby ensuring the cooling effect of the cooling water. After the air in the air outlet pipe 6 is cooled, it enters the air duct 3 in the transformer again and absorbs heat again. The above process is repeated to achieve heat dissipation of the transformer.

[0037] The above are only preferred specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
