It has higher heat exchange efficiency and better heat dissipation effect than the traditional single air cooling method. This invention enhances airflow efficiency between heat sinks by incorporating ventilation openings on the heat sinks. A regulating component drives an adjusting frame to rotate, thereby raising and lowering several heat sinks to adjust their positions. Simultaneously, changing the position of the ventilation openings alters the airflow direction within the heat dissipation unit, thus adjusting the heat dissipation effect. To improve the structural strength of the adjusting frame, several reinforcing plates are fixedly connected to its inner wall. The corrective positioning component of this invention supports each heat sink fin with a pusher plate, ensuring consistent spacing between them. Simultaneously, the pusher plate and the mating groove limit the heat sink fins, preventing tilting or displacement during adjustment by the connecting parts. This maintains the vertical stability of each heat sink fin, ensuring stable airflow through the ventilation openings. Furthermore, during spray cooling, water mist can fall freely, achieving thorough cooling of all parts of the heat sink fins. The pusher frame and pusher plate are moved up and down via a lifting guide rail. The pusher plate pushes along the gaps between the heat sink fins, removing impurities and contaminants. When a heat sink fin deforms due to high temperature or external force, the pusher plate can push it back to its original position by moving within the cavity, thus correcting the positioning of the heat dissipation unit.

[0018] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0019] like Figures 1 to 8As shown in the embodiment of the present invention, a transformer external forced circulation water cooling heat dissipation device is provided, including a mounting frame 101. A monocrystalline silicon photovoltaic panel 102 is fixedly connected to the top of the mounting frame 101. It is also equipped with an energy storage lithium battery pack 506 and an intelligent charge / discharge controller, forming a solar power supply system with the monocrystalline silicon photovoltaic panel 102. Under daylight conditions, the photovoltaic panel 102 converts solar energy into electrical energy and stores it in the lithium battery pack 506 for the overall operation of the device. When there is insufficient sunlight or the stored energy is lower than a preset value (e.g., 20%) at night, the system automatically switches to mains power supply mode. An AC / DC conversion module ensures the continuous and stable operation of the device's electrical components, achieving synergy between clean energy and the traditional power grid, thereby saving energy. A heat dissipation mechanism 2 is provided in the middle of the mounting frame 101. The heat dissipation mechanism 2 includes two symmetrically arranged heat dissipation components. A water supply component 5 is provided below the heat dissipation mechanism 2. Spray components 3 are provided on both sides of the water supply component 5. The spray components 3 include... The bottom pipe 301 has several branch nozzles 302 fixedly connected to its top. Each branch nozzle 302 has an atomizing nozzle 303 fixedly installed at its end. The atomizing nozzles 303 are all inclined toward the heat dissipation mechanism 2. This application uses water mist sprayed directly onto the heat sink 204 to dissipate heat through the atomization and evaporation of the water mist. The cooling water is converted into micron-sized water mist through the atomizing nozzles 303. After making full contact with the surface of the heat dissipation component, the phase change evaporation is completed quickly. By utilizing the latent heat of phase change of water, the heat accumulated on the heat sink 204 is quickly removed, significantly reducing the temperature rise rate of the equipment. The heat exchange efficiency is higher than that of the traditional single air cooling method.

[0020] Please see Figure 2 The heat dissipation assembly includes a side frame 201. Two heat dissipation units arranged vertically are slidably mounted on the inner wall of the side frame 201. Each heat dissipation unit includes a heat dissipation mounting plate 202, with several heat dissipation fins 204 on one side. To achieve stable heat dissipation for transformers of different sizes, this application separates the two heat dissipation units and slidably connects them to the side frame 201, allowing for vertical height adjustment. Specifically, the inner wall edge of the side frame 201 has movable grooves, and the edge of the heat dissipation mounting plate 202 of the heat dissipation unit is slidably mounted within these grooves. Several locking bolts 203 are rotatably connected to both sides of the side frame 201. The ends of the locking bolts 203 abut against the edge of the heat dissipation mounting plate 202. Tightening the locking bolts 203 by rotating them increases the resistance to the heat dissipation mounting plate 202, thus helping to fix the heat dissipation mounting plate 202 in the height direction.

[0021] In one embodiment, see Figure 1Both sides of the mounting bracket 101 are fixedly connected to the transverse support bracket 103, and the middle of the two side brackets 201 are slidably connected to the transverse support bracket 103. By setting the transverse support bracket 103, the horizontal fixation of the heat dissipation component is assisted. The load of the heat dissipation component is distributed by the transverse support bracket 103 and locking bolts 203, so as to avoid the problem that the entire weight of the heat dissipation mechanism 2 is supported by the transformer body after installation, which would cause the transformer body to be easily deformed and damaged.

[0022] In one embodiment, see Figure 3 To further improve the heat dissipation effect of the heat sink 204, ventilation openings 205 are provided in the middle of several heat sinks 204. These ventilation openings 205 enhance the airflow efficiency between the heat sinks. Please refer to [link / reference]. Figure 4 An adjustment groove is provided in the middle of one side of the heat dissipation mounting plate 202. An adjustment component 207 for adjusting the height of the heat sink 204 is provided inside the adjustment groove. Several docking grooves 206 are provided on the side of the heat dissipation mounting plate 202 near the adjustment groove. The edges of several heat sinks 204 are slidably connected to several docking grooves 206 respectively. The docking grooves 206 are used to guide and limit the lifting and lowering movement of the heat sinks 204.

[0023] In one embodiment, see Figure 5 The adjustment assembly 207 includes an adjustment frame 2071. Several adjustment motors 2072 are fixedly installed on the inner wall of the adjustment frame 2071. Adjustment gears 2073 are fixedly connected to the output ends of the adjustment motors 2072. Several adjustment guide grooves 209 are formed on the inner wall of the adjustment groove. The adjustment gears 2073 are rotatably installed within the adjustment guide grooves 209. The adjustment motors 2072 drive the adjustment gears 2073 to rotate, and the friction between the adjustment gears 2073 and the adjustment guide grooves 209 drives the adjustment frame 2071 to rotate and shift as a whole. A number of connectors 208 are rotatably mounted on the side for connecting the heat sink 204. The movement of the connectors 208 drives the heat sink 204 to move. The adjustment component 207 of this application drives the adjustment frame 2071 to rotate, thereby driving the heat sink 204 to rise and fall and move, thereby adjusting the position of the heat sink 204. At the same time, it changes the position of the vent 205 and changes the airflow direction inside the heat dissipation unit, thereby adjusting the heat dissipation effect. In order to improve the structural strength of the adjustment frame 2071, a number of reinforcing plates 2074 are fixedly connected to the inner wall of the adjustment frame 2071.

[0024] In one embodiment, see Figure 6Since the connector 208 will move synchronously with the rotation of the adjusting frame 2071, in order to ensure a stable connection to the heat sink 204 during the movement, the connector 208 itself includes a rotating column 2081. The top of the rotating column 2081 is rotatably connected to a support frame 2082. The top of the support frame 2082 is provided with a displacement groove. The inner wall of the displacement groove is slidably connected to a docking plate 2083. One side of the docking plate 2083 is fixedly connected to the heat sink 204. The inner wall of the displacement groove is provided with a limiting groove. The side of the docking plate 2083 near the displacement groove is fixedly connected to a limiting post 2084. The limiting post 2084 is slidably connected to the inner wall of the limiting groove. In this way, the docking plate 2083 and the heat sink 204 connected to it can rotate at a certain angle and slide within a certain distance, so as to achieve stable movement and adjustment of the heat sink 204.

[0025] In one embodiment, see Figure 3 To improve the heat dissipation and ventilation effect inside the heat dissipation unit, air inlets corresponding to the positions of each heat dissipation unit are opened on both sides of the side frame 201. Natural air is introduced through the air inlets, and the heat dissipation unit is cooled by side air intake. In practical implementation, a fan 211 can be installed on the inner wall of the air vent by covering one side of the air vent with a fan 210. When there is no natural wind, the rotation of the fan 211 can be used to accelerate the airflow and force airflow to achieve heat dissipation.

[0026] In one embodiment, see Figure 1 and Figure 7Each of the two heat dissipation components has a trimming and positioning component 4 on one side. The trimming and positioning component 4 includes a lifting guide rail 403, and a pusher frame 401 is slidably installed on the inner wall of the lifting guide rail 403. Several pusher plates 402 are fixedly connected to the bottom of one side of the pusher frame 401. The pusher plates 402 are respectively positioned corresponding to the gaps between several heat dissipation fins 204, and the width of the pusher plates 402 is the same as the width of the gaps. The technical effects achieved by setting the trimming and positioning components in this application are as follows: First, the presence of the pusher plates 402 supports each heat dissipation fin 204, making the spacing between each heat dissipation fin 204 consistent. At the same time, the pusher plates 402 and the docking groove 206 limit the heat dissipation fins 204, preventing the heat dissipation fins 204 from tilting and shifting as the connecting piece 208 rotates during the adjustment of the adjusting frame 2071, keeping the posture of each heat dissipation fin 204 vertical and stable, thereby ensuring airflow. The stable passage of water through the vent 205 allows the water mist to fall freely during spray cooling, achieving sufficient cooling of all parts of the heat sink 204. Secondly, the lifting guide rail 403 drives the pusher frame 401 and pusher plate 402 to move up and down. The pusher plate 402 pushes along the gaps between the heat sinks 204, removing impurities and dirt blocking the gaps. Simultaneously, when the heat sink 204 deforms due to high temperature or external force, the pusher plate 402 can push the heat sink 204 back to its original position by moving within the cavity, thus correcting the positioning of the heat dissipation unit. Thirdly, if the water flow from the atomizing nozzle 303 is not completely evaporated by the heat of the heat sink 204, it will drip to the bottom of the device, contaminating the water supply component 5 and the ground. This application uses the pusher plate 402 to seal the bottom of the gaps in the heat sink 204, thereby collecting the sprayed atomized water flow for centralized treatment.

[0027] In one embodiment, see Figure 1 and Figure 8 The water supply component 5 includes a water tank 501. Two partitions 502 are fixedly connected to both sides of the water tank 501. A device box 505 is set between the two partitions 502. The device box 505 is equipped with a lithium battery pack 506 and a power supply system component such as a charge and discharge controller. The specific structure is implemented according to the technical solution of the existing photovoltaic power supply control component. One end of the water tank 501 is fixedly connected to a water inlet pipe 503. One end of the water inlet pipe 503 is connected to an external water source. The device box 505 is set as a square box and is tilted so that one edge faces the port of the water inlet pipe 503. In this way, the device box 505 is directly in contact with the water flow sent by the water inlet pipe 503 to achieve cooling of the device box 505 and the internal components, so as to ensure the long-term stable operation of each component. In one embodiment, in order to deliver water to the spray assembly 3, two spray water pumps 511 are provided on one side of the inner wall of the water tank 501. The outlet ends of the two spray water pumps 511 are fixedly connected to connecting pipes. One end of the two connecting pipes is fixedly connected to the middle of the two partitions 502 respectively. Both ends of the water tank 501 are fixedly connected to discharge pipes 504. The two discharge pipes 504 are fixedly connected to the two bottom pipes 301 respectively.

[0028] In one embodiment, to further improve the heat dissipation effect of water flow on the device box 505, a positioning plate 508 is fixedly connected to the side of the device box 505 away from the water inlet pipe 503. A guide plate 507 is fixedly connected to both sides of the positioning plate 508. The guide plate 507 is inclined and parallel to the side wall of the device box 505. The water flow is made to flow in a way that fits the side wall of the device box 505 through the support of the guide plate 507, so as to achieve efficient heat dissipation of the device box 505. An outlet 509 is opened on one side of the guide plate 507. A water guide cover 510 is fixedly connected to the outlet 509. A water guide pipe is fixedly connected to one side of the water guide cover 510. The two water guide pipes are fixedly connected to the inlet of the two jet water pumps 511 respectively.

[0029] In one embodiment, to treat the water accumulated on the pusher frame 401, a return water pump 513 is fixedly installed on both sides of the top of the water tank 501. The inlet ends of the two return water pumps 513 are fixedly connected to return hoses 512. One end of the two return hoses 512 is fixedly connected to the top of one side of the two pusher frames 401 respectively. The outlet ends of the two return water pumps 513 are fixedly connected to return pipes. When recycling is required, the return pipes are connected to the water tank 501. In this state, a filter can be installed in the middle of the return hose 512 to facilitate the removal of impurities and avoid the problem of the atomizing nozzle 303 being blocked by the recycled water. When recycling is not required, the return pipes are connected to the sewage discharge equipment.

[0030] In use, the device is first installed by placing two sets of columns on either side of the transformer, then installing the horizontal support frame 103 in the middle of the columns. Next, two heat dissipation components are installed on either side of the transformer, and the height of the heat dissipation unit is adjusted so that one side of the heat dissipation mounting plate 202 is in contact with the heat-generating part of the transformer. The height of the heat dissipation mounting plate 202 is then fixed by tightening the locking bolts 203, using their ends to press against the edge of the heat dissipation mounting plate 202. Then, the external connectors 208 are used to fix the heat dissipation unit to the transformer and the side frame 201 to the horizontal support frame 103, thus fixing the horizontal position of the heat dissipation components. Next, the water supply component 5 is placed below the transformer, and two spray components 3 are placed on either side of the water supply component 5, adjusting their positions so that the atomizing nozzles 303 face the heat dissipation fins 204 of the heat dissipation component. The discharge pipe 504 is then connected to the bottom pipe 301. Finally, the top photovoltaic module is installed, and the power supply and photovoltaic control components are electrically connected. For the status of the device after installation, please refer to [link to relevant documentation]. Figure 1 (The transformer is not shown in the location diagram; it is located between the heat dissipation components on both sides.) During heat dissipation, the heat dissipation mounting plate 202 contacts the transformer, and heat is conducted to the heat sink 204 for dissipation. Water is pumped by the jet pump 511 to the discharge pipe 504, then sent to the distribution nozzle 302 through the bottom pipe 301, and finally sprayed out by the atomizing nozzle 303 in the form of water mist to cool the heat sink 204, thereby maintaining the low temperature of the heat sink 204 and achieving continuous cooling of the transformer. When the ambient temperature is high, the fan 211 can be activated to blow airflow into the heat dissipation unit, which then passes through several vents 205 to further cool the heat dissipation mounting plate 202 and the heat sink 204. When the temperature sensor detects that the transformer temperature is too high, the adjustment component 207 drives the heat transfer plates to move up and down, thereby changing the height of each vent 205 and guiding the airflow from the fan 211 to increase the airflow at high temperature locations. This controls the local heat dissipation capacity of the heat dissipation mounting plate 202 and maintains a stable and efficient heat dissipation effect.

[0031] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
