Description

[0002] Transformers are an essential piece of power generation technology. Due to material constraints, part of the electrical energy is converted into excess heat during operation. The heat generated by losses in the windings and core must be quickly dissipated to prevent insulation damage caused by overheating. There are a variety of cooling methods for transformers of different power levels, including natural air cooling, forced air cooling, oil-immersed natural cooling, and oil-immersed air cooling.

In this method, an oil pump is used to circulate the cooling oil, and a fan is used to dissipate the heat from the cooling oil. However, due to the high external temperature in summer, it is difficult for the transformer cooling system to ensure sufficient heat dissipation strength. Summary of the Invention

[0018] In order to make the above objects, features and advantages of the present invention more clear and understandable, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings of the specification.

[0019] Numerous specific details are set forth below to facilitate a thorough understanding of the present invention; however, the present invention may be practiced in other ways than those described herein, and similar extensions may be made by those skilled in the art without departing from the spirit of the present invention, and therefore the present invention is not limited by the specific examples disclosed below.

[0020] Also, as used herein, "one embodiment" or "embodiment" refers to a particular feature, structure, or characteristic that may be included in at least one embodiment of the present invention. The appearances of the phrase "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they mutually exclusive embodiments separate or alternative from other embodiments.

[0021] Furthermore, the present invention will be described in detail in conjunction with schematic drawings, and when describing the embodiments of the present invention in detail, for ease of explanation, the cross-sectional views showing the structure of the device are partially enlarged and not according to the normal scale, and the schematic drawings are merely illustrative and do not limit the scope of protection of the present invention, and should include three-dimensional spatial dimensions of length, width and depth during actual production.

[0022] Example 1 Referring to FIGS. 1 to 3, a first embodiment of the present invention provides a cooling device for a transformer, the cooling device for a transformer comprising: An oil tank 100, the interior of which is used to mount a transformer, an oil conservator 200 fixedly installed on the top of the oil tank 100, and cooling oil stored inside the oil conservator 200; a cooling assembly 300 including an air blowing member 301 and an oil feeding member 302 provided on one side of the oil tank 100, and a rotating member 303 and a temperature reducing member 304 provided on one side of the oil feeding member 302; The air blowing member 301 includes a storage member 401 provided on one side thereof, and an auxiliary assembly 400 including a spray member 402 provided on one side thereof.

[0023] In use, the transformer is installed inside the oil tank 100, which is filled with cooling oil. The oil conservator 200 can replenish the cooling oil in time when the cooling oil inside the oil tank 100 leaks. The cooling assembly 300 is mainly used for transporting the cooling oil and dissipating heat from the cooling oil. The auxiliary assembly 400, as an auxiliary device, can enhance the cooling effect of the cooling assembly 300.

[0024] Example 2 2 to 6, the second embodiment of the present invention differs from the first embodiment as follows: the air blowing member 301 includes an air chamber 301a, a rack 301b, a motor 301c, and a fan 301d; the air chamber 301a is fixedly mounted on the side of the oil tank 100; there are two racks 301b, each fixedly mounted on the bottom and top of the air chamber 301a; the motors 301c are fixedly mounted inside each rack 301b; the fans 301d are fixedly mounted on the output ends of the motors 301c; after starting up, the motors 301c rotate the fans 301d, and the fans 301d at the top and bottom of the air chamber 301a rotate in opposite directions; and when the fans 301d rotate, they can form an airflow from the top to the bottom of the air chamber 301a.

[0025] When the fans 301d rotate, the top fan 301d blows air toward the inside of the air chamber 301a, and the bottom fan 301d blows air toward the outside of the air chamber 301a, so that the airflow inside the air chamber 301a flows from top to bottom, allowing full contact with the duct. On the other hand, when conventional fans 301d perform cooling, the two fans 301d blow air perpendicular to the duct, limiting the area of ​​contact between the airflow and the duct and reducing the heat dissipation efficiency of the cooling oil.

[0026] The oil supply member 302 comprises an oil supply pipe 302a and an oil pump 302b. The oil supply pipe 302a is connected to the outside of the oil tank 100, and the outlet of the oil pump 302b is connected to the outside of the bottom of the oil tank 100. The oil pump 302b is used to suck the cooling oil from the top of the oil tank 100 to the outside after absorbing heat, and transport the cooling oil to the bottom of the oil tank 100 after the cooling assembly 300 dissipates the heat of the cooling oil, thereby forming a cooling oil circulation.

[0027] The oil feed member 302 further includes a spiral pipe 302c and a side edge plate 302d. The oil feed pipe 302a penetrates the outside of the air chamber 301a and extends to the inside. The spiral pipe 302c is rotatably provided at one end of the oil feed pipe 302a that is remote from the oil tank 100. The other end of the spiral pipe 302c that is remote from the oil feed pipe 302a is rotatably provided at the inlet of the oil pump 302b. The spiral pipe 302c is located between the oil feed pipe 302a and the oil pump 302b. Compared to a conventional straight pipe, The spiral tube 302c extends the time the cooling oil passes through the cooling device, thereby improving the heat dissipation effect of the cooling oil, and the side edge plate 302d is fixedly installed surrounding the side of the spiral tube 302c. The side edge plate 302d is spiral-shaped and surrounds the side of the spiral tube 302c. The side edge plate 302d is mainly used to interact with the blower member 301 and the spray member 402, thereby making full use of the spiral shape of the spiral tube 302c to achieve the purpose of improving the heat dissipation effect of the cooling oil.

[0028] The rotating member 303 includes a ring member 1 303a, a support bar 1 303b, a curved plate 1 303c, an air guide cover 303d, a ring member 2 303e, a support bar 2 303f, and a curved plate 2 303g. The ring member 1 303a is fitted and fixedly provided on the top end side of the spiral tube 302c. The support bar 1 303b is fixedly provided on one side of the ring member 1 303a. The curved plate 1 303c and the air guide cover 303d are fixedly provided on the side of the support bar 1 303b. The air guide cover 303d is fixed to the ring member 1 303e of the curved plate 1 303c. 3a, and the outer wall of the air guide cover 303d can guide the airflow to the middle section and assist the operation of the temperature reducing member 304. Ring member 2 303e is fitted into the bottom end of the spiral tube 302c and fixedly installed. Support bar 2 303f is fixedly installed on one side of ring member 2 303e. Curved plate 2 303g is fixedly installed on the side of support bar 2 303f. Curved plate 1 303c and curved plate 2 303g function like a turbine, catching the wind and rotating the support bar, which in turn rotates the spiral tube 302c.

[0029] Here, when the spiral tube 302c begins to rotate due to the driving of the rotating member 303, the side edge plate 302d comes into contact with the air flow in the air chamber 301a, and the air flow forms a rotation, thereby extending the time that the air flow around the spiral tube 302c comes into contact with the spiral tube 302c, thereby improving the heat dissipation effect of the cooling oil by the cooling assembly 300.

[0030] The temperature reducing member 304 includes a central shaft 304a, a windshield cover 304b, an air duct 304c, an intermediate cover 304d, an intake pipe 304e, an exhaust pipe 1 304f, and an exhaust pipe 2 304g. The central shaft 304a is fixedly attached to the side of the spiral pipe 302c. The windshield cover 304b is rotatably attached to the side of the central shaft 304a via a bracket. The air duct 304c is connected to the bottom of the windshield cover 304b. The windshield cover 304b receives airflow from above downwards. The air guide cover 303d increases the flow rate of the airflow received by the windshield cover 304b. The intermediate cover 304d is connected to the side of the air duct 304c. The windshield cover 304b is connected to the windshield cover 304c through the ventilation pipe 304c, and a plurality of exhaust ports are provided inside the intermediate cover 304d. The intake pipe 304e is fixedly mounted inside the intermediate cover 304d and is connected to the intermediate cover 304d through the exhaust ports. The exhaust pipes 1 304f and 2 304g are connected to different sides of the intake pipe 304e. The exhaust pipe 1 304f is located on the side of the intake pipe 304e away from the ventilation pipe 402c. The airflow inside the windshield cover 304b flows into the ventilation pipe 304c, then passes through the ventilation pipe 304c to each of the intermediate covers 304d, and further passes through each of the exhaust ports in the intermediate cover 304d to flow into the intake pipe 304e.

[0031] The temperature reducing member 304 further includes arc-shaped teeth 304h, a truncated cone 304i, an air guide ring 304j, and an air blocking groove 304k, the arc-shaped teeth 304h being fixedly provided on the inside of the air intake pipe, the truncated cone 304i being fixedly provided at the mouth of the exhaust pipe 2 304g, the air guide ring 304j being fixedly provided at the connection between the exhaust pipe 1 304f and the intake pipe 304e, and the air blocking groove 304k being provided on the inner wall of the exhaust pipe 2 304g.

[0032] Intake pipe 304e, exhaust pipe 1 304f, and exhaust pipe 2 304g form a structure similar to a vortex pipe. A vortex pipe generates cool air by utilizing the viscous friction between the inner and outer swirling layers of compressed gas inside the pipe. Its main working process is as follows: compressed gas enters the vortex pipe and forms a vortex flow. The angular velocity of the vortex flow increases toward the center, and friction occurs between the vortex layers due to the difference in angular velocity. The angular velocity of the air flow in the center is the highest, and energy is transferred to the outer layers with a lower angular velocity due to friction. The air flow in the center loses energy, its kinetic energy is small, and its speed and temperature decrease, forming a cool air flow. Meanwhile, the air flow in the outer layers gains momentum and its kinetic energy increases. At the same time, friction with the inner wall of the vortex pipe converts part of the kinetic energy into thermal energy, which is discharged from the other end of the vortex pipe, forming a hot air flow.

[0033] However, compared to conventional vortex tubes, the temperature-reducing member 304 has the following improvements: First, the arc-shaped teeth 304h improve the swirl strength within the second exhaust pipe 304g; second, the wind-blocking grooves 304k further reduce the swirl speed of the outer airflow within the second exhaust pipe 304g, so that the inner swirl within the second exhaust pipe 304g consumes more internal energy to move the outer airflow, resulting in a further reduction in the temperature of the inner airflow; and third, the middle cover 304d divides the airflow from the ventilation pipe 304c into multiple parts and directs them into the intake pipe 304e, forming swirls of uniform strength, which prevents airflows of different strengths from colliding with each other and wasting the internal energy of the gas in unnecessary places.

[0034] During use, as the operating time of the transformer increases, the cooling oil in the oil tank 100 continuously absorbs the heat released from the transformer. After being heated, the cooling oil collides and rises upward. Under the action of the oil pump 302b, it is absorbed into the spiral tube 302c through the oil supply pipe 302a. The airflow generated by the blower member 301 collides with the transmission member, thereby rotating the spiral tube 302c. The rotating spiral tube 302c is in full contact with the airflow through the side edge plate 302d, thereby improving the heat dissipation effect of the cooling assembly 300. During the rotation of the spiral tube 302c, the heat of the cooling oil is continuously absorbed by the airflow.

[0035] Part of the airflow passes through the middle cover 304d and enters the intake cover, where it is guided by the arc-shaped teeth 304h to form a swirling flow. Due to the blocking of the air guide ring 304j, most of the swirling flow enters the intake pipe 304e2, where it is relatively divided into two flows, cool air and hot air, according to the principle of vortex pipes. As it passes through the truncated cone 304i, the outer hot air flows out of the intake pipe 304e2, while the inner cold air flow is blocked. As the airflow accumulates, the cool air flows out of the exhaust pipe-1 304f. Because the exhaust pipe-1 304f is close to the spiral pipe 302c, the cool air further cools the spiral pipe 302c, thereby improving the heat dissipation effect of the cooling assembly 300.

[0036] The other structures are the same as those in the first embodiment.

[0037] Example 3 7 to 9, the third embodiment of the present invention differs from the second embodiment in the following points: the storage member 401 includes a water tank 401a, a screen 401b, a cross plate 401c, a partition plate 401d, a water hole 401e, a stepped column 401f, a stopper rod 401g, a limit plate 401h, and a buoyancy plug 401i; the water tank 401a is fixedly installed on the top of the wind chamber 301a; the water tank 401a is installed outdoors and can normally receive rainwater from the outside; the screen 401b is installed on the top of the water tank 401a; The screen 401b is mainly used to prevent waste from entering the water storage tank 401a, the cross plates 401c are fixedly installed inside the water storage tank 401a and are arranged crosswise along different heights inside the water storage tank 401a and are mainly used to block water vapor as the water evaporates, condense the water vapor on the cross plates 401c and return it to the water storage tank 401a, and the partition plate 401d is fixedly installed inside the water storage tank 401a and divides the internal space of the water storage tank 401a into upper and lower parts.

[0038] The water passage hole 401e opens at the center of the partition plate 401d, and the stepped column 401f is provided inside the water passage hole 401e so as to be able to slide freely. The stepped column 401f is divided into a thick part and a thin part, and the thick part slides out of the water passage hole 401e, so that the water in the upper part of the water storage tank 401a can flow to the bottom of the water storage tank 401a through the gap between the thin part of the stepped column 401f and the water passage hole 401e. The stopper rod 401g is The stopper rod 401g is fixedly attached to the top of the stepped column 401f, and is used to prevent the stepped column 401f from coming out of the water hole 401e. Both ends of the limit plate 401h are fixedly attached to the outside of the stepped column 401f and the bottom of the stopper rod 401g, mainly to ensure that the stepped column 401f can always slide along the inner wall of the water hole 401e when sliding. The buoyancy plug 401i is fixedly attached to the bottom of the stepped column 401f.

[0039] The spray member 402 includes a water pipe 402a, a nozzle 402b, an air pipe 402c, a slide stand 402d, an arc-shaped block 402e, a spring 402f, and an extrusion ring 402g. The water pipe 402a is connected to the lower half of the water storage tank 401a, and one end of the water pipe 402a remote from the water storage tank 401a penetrates the rack 301b and extends to the inside. The nozzle 402b is connected to the end of the water pipe 402a. One end of the air pipe 402c is connected to the bottom of the water storage tank 401a. The end of the spring 402f penetrates the outer wall of the air chamber 301a and extends into the interior of the rack 301b, the slide base 402d is slidably mounted on the inner wall of the ventilation pipe 402c, the arc-shaped block 402e is fixedly mounted on the end of the slide base 402d, both ends of the spring 402f are fixedly mounted on the side surface of the slide base 402d and the inside of the ventilation pipe 402c, and the push ring 402g is fitted onto the output end of the motor 301c, and the side wall of the push ring 402g is slidably fitted with the arc-shaped block 402e.

[0040] In use, the water tank 401a needs to be divided into two parts to form a sealed space. Without the partition 401d, when the spray element 402 applies pressure, the pressure will flow out from the top of the water tank 401a. At this time, the water mist discharged from the nozzle 402b will decrease. If there is enough water in the water tank 401a, the auxiliary assembly 400 will perform the following functions: First, after the fan 301d rotates, the side wall of the extrusion ring 402g will extrude the arc-shaped block 402e, and the arc-shaped block 402e will slide into the slide frame. 402d is slid, and after the sliding base 402d has slid, it pushes out the lower part of the water tank 401a, and since the water tank 401a is sealed, the pushed-out water flow is discharged from the nozzle 402b along the water supply pipe 402a, forming a water mist, which is then blown into the inside of the air chamber 301a by the fan 301d, and at the same time, the side edge plate 302d collects the water mist and forms water droplets, which can absorb the heat of the spiral tube 302c as they flow along the side edge plate 302d, thereby improving the heat dissipation effect of the spiral tube 302c.

[0041] When the water flow at the bottom of the water storage tank 401a is lost, the buoyancy plug 401i slides downward, and the water flow in the water storage tank 401a flows from the top to the bottom, thereby replenishing the water in the bottom of the water storage tank 401a, the water supply pipe 402a, and the air vent pipe 402c, making it possible to perform the next spraying.

[0042] The other structures are the same as those in the second embodiment.
