[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0038] This invention provides a water-cooled transformer for a high-power, high-frequency switching power supply, such as... Figures 1 to 7 As shown, it includes: a transformer 1, which is a high-power high-frequency switching power supply water-cooled transformer in the prior art; a copper busbar 2 is provided on the transformer 1; a connection hole 3 is provided on the copper busbar 2; the connection hole facilitates the connection of the copper busbar 2 to the copper busbar on external equipment; and a moisture-proof component is provided on the outside of the copper busbar 2; the moisture-proof component can prevent the copper busbar 2 from moisture.

[0039] The moisture-proof components include: a circular frame 4, a circular ring 5, a telescopic cover 6, an air outlet 7, an air duct 8, a dehumidification component for dehumidifying the airflow blown out from the air duct 8, and a support component for supporting the circular ring 5.

[0040] The circular frame 4 is fixedly installed on the outside of the transformer 1. The circular frame 4 is located outside the copper busbar 2. The air outlet 7 is set on the top of the circular frame 4. The circular ring 5 is connected to the circular frame 4 through the telescopic cover 6. The air duct 8 is set on the outside of the transformer 1. The position of the air duct 8 corresponds to that of the air outlet 7. The bottom of the air duct 8 is provided with circular holes at equal intervals.

[0041] In use, connect the duct 8 to an external blower and the copper busbar 2 to an external device. Then, pull the ring 5 to move it away from the circular frame 4, thereby unfolding the telescopic cover 6. Finally, the telescopic cover 6, together with the ring 5, covers the connection between the copper busbar 2 and the external device. The support component supports the ring 5 to keep it stationary. The blower blows air into the duct 8. The air is blown out through the circular hole, dehumidified by the dehumidification component, and then enters the space formed by the circular frame 4, the telescopic cover 6, and the ring 5 through the air outlet 7. Then it is blown outward, preventing the humid air from the outside from contacting the copper busbar 2. This prevents moisture from entering the connection between the copper busbar 2 and the external device, ensuring the normal use of the copper busbar 2 and the overall normal use of the transformer. The airflow generated in the space formed by the circular frame 4, the telescopic cover 6, and the ring 5 can also carry away the heat generated by the copper busbar 2 for heat dissipation.

[0042] like Figures 2 to 7As shown, the dehumidification assembly includes: a moisture-absorbing strip 11, a heat dissipation vent 12 opened on the outside of the transformer 1, a guide wheel 13, a drive assembly for driving the guide wheel 13 to rotate, and an adjustment assembly for adjusting the vertical position of the air duct 8.

[0043] The guide wheel 13 is rotatably installed on the outside of the transformer 1. The moisture-absorbing strip 11 is sleeved on the outside of the guide wheel 13 and the circular frame 4. The moisture-absorbing strip 11 can pass through the heat dissipation port 12. The moisture-absorbing strip 11 passes between the air duct 8 and the circular frame 4. The air duct 8 and the moisture-absorbing strip 11 are in contact.

[0044] The airflow blown out of the duct 8 is dehumidified after passing through the moisture-absorbing strip 11. After a period of time, the duct 8 is adjusted upward by the adjustment component, so that the duct 8 is away from the moisture-absorbing strip 11. Then, the drive component drives the guide wheel 13 to rotate, thereby driving the moisture-absorbing strip 11 to move, rotating the moisture-absorbing part to a position away from the duct 8. The heat inside the transformer 1 can be dissipated outward through the heat dissipation port 12. The moisture-absorbing strip 11 at the heat dissipation port 12 can be dried. As the moisture-absorbing strip 11 moves, the dried moisture-absorbing strip 11 can be moved to the duct 8. Then, the drive component stops driving the guide wheel 13, and the duct 8 is reset by the adjustment component, so that the circular frame 4 clamps the moisture-absorbing strip 11, completing the switching of the dried part of the moisture-absorbing strip 11. The above operation is repeated at intervals, so that the dried moisture-absorbing strip 11 can always be located at the duct 8 to dehumidify the airflow. The specific interval is determined according to the humidity at the site.

[0045] like Figure 3 and Figure 7 As shown, the drive assembly includes: a motor 14, a bracket, a baffle 15, a baffle 16, and a rectangular groove formed on the outside of the guide wheel 13;

[0046] The motor 14 is fixedly installed on the outside of the transformer 1 by a bracket. The baffle 15 is fixedly sleeved on the output shaft of the motor 14. The end of the output shaft of the motor 14 matches the rectangular groove and extends into the rectangular groove. The baffle 16 is set on the outside of the air duct 8. Both the baffle 15 and the baffle 16 are in contact with the outside of the moisture-absorbing strip 11.

[0047] The baffle 15 and the baffle 16 can limit the moisture-absorbing strip 11 so that it cannot be separated from the circular frame 4. The motor 14 is started so that its output shaft cooperates with the rectangular groove to rotate the guide wheel 13. The guide wheel 13 drives the moisture-absorbing strip 11 to rotate by the friction between it and the moisture-absorbing strip 11.

[0048] like Figures 2 to 7As shown, an arc-shaped groove is provided on the outside of the transformer 1, and an arc-shaped tube 17 is provided inside the arc-shaped groove. The top of the air duct 8 is connected to a connecting pipe 9, and a connector pipe 10 is connected to one side of the connecting pipe 9. The top of the connecting pipe 9 is connected to the arc-shaped tube 17 through a flexible hose 18. Specifically, one end of the flexible hose 18 passes through the transformer 1 and connects to the arc-shaped tube 17. A solenoid valve 19 is provided inside the connecting pipe 9. The solenoid valve 19 is located below the connector pipe 10. An opening is provided on the outside of the arc-shaped tube 17. The opening is directly opposite the side of the moisture-absorbing strip 11. When the air duct 8 is at the bottom, the air duct 8 can close the opening on the arc-shaped tube 17. A filter screen is provided at the air inlet of the external blower. The air can be filtered through the filter screen to prevent dust and impurities from entering the air duct 8.

[0049] When the air duct 8 comes into contact with the moisture-absorbing strip 11, the solenoid valve 19 opens, connecting the connector pipe 10 to the external blower. The airflow blown out by the blower enters the connecting pipe 9 through the connector pipe 10. Since the opening of the arc-shaped pipe 17 is closed by the air duct 8 at this time, the airflow can only enter the air duct 8 and then blow out through the round hole. If the environment is humid and accompanied by a small amount of dust, the dust will fall on the dried moisture-absorbing strip 11. This part of the dust will hinder the airflow through the moisture-absorbing strip 11 and affect the moisture-proof process.

[0050] Therefore, when the duct 8 rises, the duct 8 releases the seal on the opening. At this time, the solenoid valve 19 closes, and the airflow enters the arc-shaped pipe 17 through the hose 18. It blows outward through the opening, which can blow away the dry moisture-absorbing strip 11 that moves to the bottom of the duct 8, thereby blowing away the dust and impurities on the surface of the moisture-absorbing strip 11 and cleaning the moisture-absorbing strip 11. Then the duct 8 returns to its original position, the solenoid valve 19 opens, and the airflow blown out from the duct 8 will not be obstructed by dust and impurities, ensuring the moisture-proof effect.

[0051] like Figure 4 As shown, the adjustment assembly includes: slider 20, electromagnet 21, and spring 22;

[0052] A slide groove is provided on the outside of the transformer 1. The slider 20 is slidably installed in the slide groove. The slider 20 is fixedly connected to the air duct 8. The slider 20 is made of a material that can be magnetically attracted. The material of the slider 20 is iron. The spring 22 fixes the top of the slider 20 to the top wall of the slide groove. The electromagnet 21 is fixedly installed on the top wall of the slide groove.

[0053] When electromagnet 21 is energized, it becomes magnetic, attracting slider 20 and causing it to lift duct 8. This causes baffle 16 to move accordingly. As slider 20 rises, spring 22 is compressed and deformed. Eventually, duct 8 leaves moisture-absorbing strip 11 and the opening is no longer sealed. Baffle 16 also stops blocking the opening. When electromagnet 21 is de-energized, spring 22 returns to its original position, causing slider 20 and duct 8 to return to their original positions, making duct 8 come into contact with moisture-absorbing strip 11.

[0054] like Figure 3 As shown, the support assembly includes: a sleeve 23, a sliding rod slidably disposed inside the sleeve 23, and a fixing plate 24;

[0055] Bushings 23 are symmetrically fixedly installed on the outside of transformer 1. Bushings 23 are located on both sides of circular frame 4. Fixing plate 24 is slidably installed on one end of slide rod. The outer side of circular ring 5 has a groove corresponding to fixing plate 24. Fixing plate 24 extends into the groove. Fixing plate 24 and circular ring 5 are connected by bolts.

[0056] When it is necessary to replace the moisture-absorbing strip 11, remove the bolts, pull the fixing plate 24 to slide it away from the groove, then raise the air duct 8 so that the baffle 16 can no longer restrict the moisture-absorbing strip 11, disassemble the bracket so that the output shaft of the motor 14 can leave the guide wheel 13, and at this time the moisture-absorbing strip 11 can be removed for replacement.

[0057] like Figure 3 As shown, the moisture-absorbing strip 11 is a mesh fabric bonded with moisture-absorbing silicone particles, and the circular frame 4 is made of stainless steel. The outer side of the circular frame 4 is smooth, and the guide wheel 13 can drive the moisture-absorbing strip 11 to move when it rotates in conjunction with friction.

[0058] Working principle: In use, connect the connector pipe 10 to the output end of the external blower, connect the copper busbar 2 to the external equipment, and then pull the ring 5 to move it away from the circular frame 4, thereby unfolding the telescopic cover 6. Finally, the telescopic cover 6, together with the ring 5, covers the connection between the copper busbar 2 and the external equipment. The support component supports the ring 5 to keep it stationary. Air is blown into the air duct 8 by the blower. The airflow blown by the blower enters the connecting pipe 9 through the connector pipe 10. Since the opening of the arc-shaped pipe 17 is closed by the air duct 8 at this time, This airflow can only enter the duct 8, and then blow out through the round hole. After being dehumidified by the moisture-absorbing strip 11, it enters the space formed by the round frame 4, the telescopic cover 6, and the ring 5 through the air outlet 7, and then blows outward, so that the humid air outside cannot come into contact with the copper busbar 2. This can prevent moisture from entering the connection between the copper busbar 2 and the external equipment, thus ensuring the normal use of the copper busbar 2 and the normal use of the transformer as a whole. In addition, the airflow generated in the space formed by the round frame 4, the telescopic cover 6, and the ring 5 can carry away the heat generated by the copper busbar 2 and dissipate it.

[0059] The airflow blown out of the duct 8 is dehumidified after passing through the moisture-absorbing strip 11. After a period of time, the duct 8 is adjusted upward by the adjustment component so that the duct 8 is away from the moisture-absorbing strip 11. Then, the guide wheel 13 is driven to rotate by the drive component, thereby driving the moisture-absorbing strip 11 to move and rotate the moisture-absorbing part to leave the duct 8. The heat inside the transformer 1 can be dissipated to the outside through the heat dissipation port 12. The moisture-absorbing strip 11 at the heat dissipation port 12 can be dried. As the moisture-absorbing strip 11 moves, the dried moisture-absorbing strip 11 can be moved to the duct 8. Then, the drive component stops driving the guide wheel 13, and the duct 8 is reset by the adjustment component so that the circular frame 4 clamps the moisture-absorbing strip 11, completing the switching of the dried part of the moisture-absorbing strip 11. The above operation is repeated at intervals to ensure that the dried moisture-absorbing strip 11 is always located at the duct 8 to dehumidify the airflow. The specific interval is determined according to the humidity at the site.

[0060] When the air duct 8 comes into contact with the moisture-absorbing strip 11, the solenoid valve 19 opens, connecting the connector pipe 10 to the external blower. The airflow blown out by the blower enters the connecting pipe 9 through the connector pipe 10. Since the opening of the arc-shaped pipe 17 is closed by the air duct 8 at this time, the airflow can only enter the air duct 8 and then blow out through the round hole. If the environment is humid and accompanied by a small amount of dust, the dust will fall on the dried moisture-absorbing strip 11. This part of the dust will hinder the airflow through the moisture-absorbing strip 11 and affect the moisture-proof process.

[0061] Therefore, when the duct 8 rises, the duct 8 releases the seal on the opening. At this time, the solenoid valve 19 closes, and the airflow enters the arc-shaped pipe 17 through the hose 18. It blows outward through the opening, which can blow away the dry moisture-absorbing strip 11 that moves to the bottom of the duct 8, thereby blowing away the dust and impurities on the surface of the moisture-absorbing strip 11 and cleaning the moisture-absorbing strip 11. Then the duct 8 returns to its original position, the solenoid valve 19 opens, and the airflow blown out from the duct 8 will not be obstructed by dust and impurities, ensuring the moisture-proof effect.

[0062] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
