[0002] A solar transformer is an electrical device used in photovoltaic systems that can change the AC voltage while keeping the AC frequency unchanged. Its main functions in photovoltaic systems include electrical isolation, component PID suppression, and voltage matching. In photovoltaic power generation systems, the application of transformers is crucial. It is not only related to the efficiency and stability of the system, but also directly affects the operating cost and maintenance difficulty of the system. Therefore, the cooling structure of the transformer is of great significance to maintaining the normal operation of the transformer.

[0003] The specification of Chinese invention patent CN118155990B discloses a high-efficiency heat dissipation device for transformers that is easy to maintain. The water pipe is squeezed by an extrusion plate, so that the cross-section of the contact part between the water pipe and the extrusion plate changes from a circle to an ellipse, thereby increasing the contact area between the water pipe and the winding, thereby taking away more heat from the winding and improving the cooling effect of the cooling water on the winding; by reducing the cross-sectional area of ​​the part of the water pipe squeezed by the extrusion plate, the flow rate of the cooling water passing through the above part is accelerated, so that the heat exchange rate of the above part is accelerated, thereby improving the cooling effect of the winding at the above part.

[0010] As a further improvement of the present application, the surfaces of the water cooling tube and the adjusting belt are provided with anti-slip grooves, and the adjusting belt is always in a straight state, and the extrusion friction contact force between the adjusting belt and the water cooling tube is not less than the water cooling tube's own weight.

[0030] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0031] The first implementation method:

[0032] Figure 1-4A solar transformer cooling device is shown, comprising a transformer body 1, a ventilation hole is opened on the surface of the transformer body 1, and a waterproof breathable plate is installed inside the ventilation hole, a plurality of windings 3 are installed inside the transformer body 1, and a water cooling pipe 6 with an elliptical cross-section is spirally fitted on the surface of the winding 3, a water circulator 2 is installed on the top of the transformer body 1, and both ends of the water cooling pipe 6 extend to the inside of the water circulator 2, a fan 4 is installed above the winding 3, and a reciprocating unit is installed on the top of the winding 3, the reciprocating unit comprises a coupling rod 7 connected to the output shaft of the fan 4, the surface of the coupling rod 7 is connected with a first bevel gear set 8 and a second bevel gear set 9 arranged up and down, and two vertically arranged lead screws 10 are installed above the winding 3 through the first bevel gear set 8 and the second bevel gear set 9, and each lead screw 10 is provided with a threaded area in opposite directions on the surface, a moving sleeve 15 is threadedly connected to the surface of the threaded area, an adjusting belt 5 is connected to the surface of the moving sleeve 15, and the surface of the adjusting belt 5 is pressed and contacted with the surface of the water cooling pipe 6, and the bottom of the winding 3 is connected with a reset member through an automatic reset shaft.

[0033] Figure 5 As shown, the reset member includes a gear 13 fixedly sleeved on the surface of the automatic reset shaft, and the surface of the gear 13 is meshedly connected with a vertically arranged No. 1 rack group 12 and a No. 2 rack group 14, and the No. 1 rack group 12 and the No. 2 rack group 14 are both composed of two racks, and the tail ends of the No. 1 rack group 12 and the No. 2 rack group 14 are connected to the tail end of the adjustment belt 5.

[0034] Specifically, when providing internal cooling service for the solar transformer body 1, the fan 4 may be started first to enhance the airflow exchange inside and outside the transformer body 1 through the ventilation holes, thereby achieving air-cooling heat exchange;

[0035] When the fan 4 rotates, the coupling rod 7 is driven to rotate, and then the first bevel gear set 8 and the second bevel gear set 9 on the surface are driven to rotate. Under the cooperation of the first bevel gear set 8 and the second bevel gear set 9, the two lead screws 10 are driven to rotate, so that the moving sleeves 15 on the surfaces of the lead screws 10 are in the process of approaching each other. At this time, the moving sleeve 15 drives the adjustment belt 5 to move upward, and then drives the water-cooling tube 6 in the squeeze contact state of the adjustment belt 5 to gradually flip along the surface of the winding 3, so as to achieve a change in the contact area between the water-cooling tube 6 and the surface of the winding 3 (such as Figure 6 As shown), in addition, when the movable sleeves 15 move away from each other, under the action of the automatic reset shaft, the gear 13 rotates, driving the No. 1 rack set 12 and the No. 2 rack set 14 to move horizontally, so as to ensure that the adjustment belt 5 is still kept in a tight state during the reset process (so as to more conveniently ensure the extrusion contact state between the adjustment belt 5 and the water-cooling pipe 6). In this process, the area where the water-cooling pipe 6 contacts the surface of the winding 3 with water cooling changes here, forming a dynamic water cooling treatment, which, combined with air cooling heat dissipation, can comprehensively improve the heat dissipation efficiency in the transformer body 1;

[0036] In addition, as the water-cooling tube 6 gradually turns over along the surface of the winding 3, the water in the water-cooling tube 6 changes dynamically, so that the cooling liquid inside the water-cooling tube 6 can change into the inner and outer layers, further improving the heat exchange degree.

[0037] Pulley shafts 11 corresponding to the adjustment belts 5 are arranged near the top and bottom ends of the surface of the winding 3, and the cross-sectional width value of the projection of the pulley shaft 11 in the vertical direction is greater than the cross-sectional width value of the projection of the water-cooling tube 6 in the vertical direction, and the adjustment belt 5 is wrapped around the surface of the pulley shaft 11.

[0038] Specifically, the pulley shaft 11 guides the adjustment belt 5 and can limit and lift the top and bottom ends of the water-cooling tube 6 in the flipped displacement state to prevent the water-cooling tube 6 from detaching from the surface of the winding 3, thereby ensuring the water-cooling contact area of ​​the surface of the winding 3.

[0039] The surfaces of the water cooling tube 6 and the adjusting belt 5 are both provided with anti-slip grooves, and the adjusting belt 5 is always in a straight state. The extrusion friction contact force between the adjusting belt 5 and the water cooling tube 6 is not less than the self-weight of the water cooling tube 6.

[0040] Specifically, the frictional contact between the adjustment belt 5 and the water-cooling tube 6 can prevent the water-cooling tube 6 from sliding down due to gravity during the flipping and displacement process, thereby ensuring smooth flipping and heating operations.

[0041] like Figure 7-8 It is shown that the connection between the movable sleeve 15 and the adjusting belt 5, the multiple racks in the No. 1 rack group 12 and the No. 2 rack group 14 and the adjusting belt 5 are all through-connected, and the tail ends of the multiple adjusting belts 5 are respectively wrapped around the bottom of the movable sleeve 15 and the multiple racks, and the bottom of the movable sleeve 15 and the multiple racks are both installed with an electromagnetic frame 16, and the inside of the electromagnetic frame 16 is slidably connected with a magnetic moving part 17, and the magnetic moving part 17 is fixedly connected to the tail end of the adjusting belt 5.

[0042] Specifically, by adjusting the length of the adjusting belt 5, the degree of extrusion contact of the adjusting belt 5 on the water-cooling tube 6 can be indirectly adjusted, thereby controlling the degree of deformation of the water-cooling tube 6, thereby adjusting the contact area between the water-cooling tube 6 and the surface of the winding 3. The electromagnetic frame 16 generates a force of mutual repulsion with the magnetic moving part 17, so that the distance between the electromagnetic frame 16 and the magnetic moving part 17 is increased, which will tighten the ends of the adjusting belt 5, thereby increasing the compression degree of the water-cooling tube 6. On the contrary, the electromagnetic frame 16 and the magnetic moving part 17 attract each other and reduce the distance between the two, so that the ends of the adjusting belt 5 are relaxed, which will reduce the contact area between the water-cooling tube 6 and the winding 3 (such as Fig. 9 as shown).

[0043] It also includes a cooling control system, which includes a temperature monitoring module and an adjustment control module. The temperature monitoring module includes a temperature sensor installed inside the transformer body 1 and the water circulator 2, which is used to monitor the cooling temperature in the water cooling pipe 6 and the temperature in the transformer body 1. The adjustment control module is connected to the electromagnetic frame 16 signal and is used to control the horizontal distance value between the electromagnetic frame 16 and the magnetic moving part 17.

[0044] Specifically, by detecting the cooling temperature in the water-cooling tube 6 and the temperature in the transformer body 1, the temperature difference between the two is determined. If the temperature difference exceeds a threshold value (the threshold value is a threshold value set according to actual conditions and is not fixed), the adjustment belt 5 needs to be tightened. At this time, the electromagnetic frame 16 and the magnetic moving part 17 repel each other. If the temperature difference is within the threshold range, the adjustment belt 5 needs to be loosened so that the electromagnetic frame 16 and the magnetic moving part 17 attract each other.

[0045] The second implementation method:

[0046] Fig.10 It is shown that the inner wall of the water-cooling tube 6 is provided with rib stripes, and a plurality of electric variable strips 18 made of elastic material are installed inside the water-cooling tube 6 , and the initial diameter value of the electric variable strips 18 is less than one-fifth of the short axis length value of the water-cooling tube 6 .

[0047] A small suction pump and a liquid storage frame are installed inside the transformer body 1, and the interior of the liquid storage frame is filled with electrorheological fluid. The liquid storage frame, the small suction pump and the electrorheological strip 18 are connected by pipes. A liquid turbidity sensor and an ultrasonic sensor are installed inside the water cooling pipe 6, and the liquid turbidity sensor and the ultrasonic sensor are both electrically connected to the suction pump and the electrorheological strip 18.

[0048] The electrorheological strip 18 is in a deflated state in an initial state, and the electrorheological strip 18 is filled with electrorheological fluid and then energized and solidified.

[0049] Different from the first embodiment, this embodiment effectively improves the cleaning of stains on the inner wall of the water-cooling tube 6, thereby avoiding the deposition of stains on the inner wall of the water-cooling tube 6 due to long-term use, reducing the thermal conductivity of the water-cooling tube 6, and thus ensuring the cooling effect of the water-cooling tube 6 on the surface of the winding 3.

[0050] Specifically, in the initial state, the electric transformer bar 18 is in a shriveled state, so it occupies a small space inside the water cooling tube 6, and does not cause significant interference to the flow of hot and cold liquids inside the water cooling tube 6;

[0051] When the liquid turbidity sensor detects that the liquid turbidity inside the water-cooling tube 6 is relatively large or the ultrasonic sensor detects that there are deposited stains on the inner wall of the water-cooling tube 6, the suction pump is started to fill the electrorheological fluid into the electrorheological strip 18, so that the electrorheological strip 18 is filled. Since the electrorheological strip 18 is made of elastic material, the diameter will increase after more liquid is filled inside. Then, power is turned on to solidify the electrorheological strip 18 in the water-cooling tube 6 (such as Fig.11 As shown), the fan 4 is then started, and the adjusting belt 5 is moved up and down, thereby driving the water-cooling tube 6 to flip. During this process, the rib stripes inside the water-cooling tube 6 and the electric transformer strips 18 with increased diameter and solidified have a rubbing effect, so that the stubborn stains deposited on the inner wall of the water-cooling tube 6 can be scrubbed and cleaned, and then discharged from the inside of the water-cooling tube 6 (the tail end of the water-cooling tube 6 can be connected to the input end of another suction pump, and the cleaned sewage can be sucked out and then the cooling liquid can be refilled into the water-cooling tube 6).

[0052] In summary, when the solar transformer body 1 is cooled, the fan 4 is started to drive the transformer body 1 to perform air cooling and heat dissipation. At the same time, the lead screw 10 rotates, driving the movable sleeves 15 to approach each other and then move away from each other, and can drive the adjusting belt 5 to rise and fall, thereby driving the water-cooling tube 6 to gradually flip along the surface of the winding 3, driving the cooling liquid in the water-cooling tube 6 to flip and replace, and can also drive the water-cooling tube 6 to perform dynamic water cooling treatment on the winding 3. Combined with air cooling and heat dissipation, it can provide a more uniform and efficient cooling treatment for the winding 3 inside the transformer body 1. In addition, in order to achieve the cleaning of the inside of the water-cooling tube 6, when cleaning is needed, the internal electric variable strip 18 can be filled with electrorheological fluid and energized to solidify, and then the rib strips inside the water-cooling tube 6 and the expanded and solidified electric variable strip 18 are driven to rub against each other under the lifting and falling changes of the adjusting belt 5, so as to effectively clean the stubborn stains deposited on the inner wall of the water-cooling tube 6.

[0053] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
