DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-11 A transformer heat sink water-cooling and air-cooling integrated device comprises a transformer body 1, a heat sink cover 2 and a water storage tank 3. The transformer body 1 is provided with heat sinks 11 and heat sink covers 2 for dissipating heat from the heat sinks 11 all around. Several heat sinks 2 are connected by three-way pipes 4, and the water storage tank 3 is connected to one of the three-way pipes 4. A temperature sensor is provided inside the heat sink 11 for monitoring the temperature of the heat sink 11. Different temperature alarm values ​​are set for air cooling and water cooling respectively. When the set temperature value is reached, the corresponding air cooling or water cooling is started to accelerate the heat dissipation. Since the energy consumption and energy loss of water cooling are more serious, it is more appropriate to use air cooling when the heat dissipation requirement is not high.

[0033] The inner top of the heat dissipation cover 2 is provided with a plurality of spray pipes 21 located above the heat dissipation fins 11, and the bottom of the spray pipes 21 is provided with a plurality of spray heads 22. The spray heads 22 are adjustable, which facilitates the user to adjust the spray form of the spray heads to atomization or droplet before installing the heat dissipation cover 2, and is more convenient to use.

[0034] An air guide cover 24 is provided on one side of the inner wall of the heat dissipation cover 2, and a fan 25 with one side extending into the inside of the air guide cover 24 and not less than one fan is embedded in the bottom of one side of the heat dissipation cover 2, a plurality of ventilation holes are provided on one side of the inner wall of the air guide cover 24, and an air guide baffle 241 is provided in the middle position of one side of the inner wall of the air guide cover 24, and one end of the air guide baffle 241 extends to the middle position of one side of the fan 25.

[0035] A filter box 26 is also provided at the bottom of one side of the heat dissipation cover 2. The filter box 26 is located on one side of the plurality of fans 25. No less than two filter screens 261 are provided inside the filter box 26. A filter screen 262 is embedded on the side of the filter box 26 away from the heat dissipation cover 2.

[0036] As a specific technical solution of this embodiment, water inlet joints 23 are provided at both ends of the top of the heat dissipation hood 2, and the bottom ends of the two water inlet joints 23 are respectively connected to the two ends of the spray pipes 21 inside the heat dissipation hood 2, and the several spray pipes 21 inside the heat dissipation hood 2 are interconnected, and two adjacent water inlet joints 23 are connected through a three-way pipe 4.

[0037] In this implementation plan, refer to Figure 1 The two adjacent water inlet joints 23 on two adjacent heat dissipation covers 2 are connected to each other through a three-way pipe 4. This design makes it possible for the spray pipes 21 inside the multiple heat dissipation covers 2 to be connected to the clean water tank 31 through only one of the three-way pipes 4. The pump 33 is started to extract the water inside the clean water tank 31 and transport it to the three-way pipe 4 connected to the water inlet joint 23 through the clean water pipe 35. The water can then flow into the spray pipes 21 inside the multiple heat dissipation covers 2 through the three-way pipe 4 and be sprayed out through the spray head 22 to cool the heat sink 11.

[0038] As a specific technical solution of this embodiment, the inner bottom of the heat dissipation cover 2 is low in the middle and high on both sides, and water collecting joints 202 are provided at the bottom of both sides of the heat dissipation cover 2. One end of the water collecting joint 202 extends to the interior of the heat dissipation cover 2 and is connected to the low-lying part of the inner bottom of the heat dissipation cover 2. Two adjacent water collecting joints 202 are connected by a three-way pipe 4.

[0039] In the present embodiment, the inner bottom of the heat dissipation hood 2 is designed to be low in the middle and high on both sides, so as to collect the water sprayed out from the sprinkler head 22 to cool the heat sink 11, and collect it into the circulation box 32 through the water collecting joint 202, the three-way pipe 4 and the circulation pipe 36. A filter is provided at the input end of the pump 2 34 to filter the water collected in the circulation box 32, and then transport it to the clean water tank 31 for continued use after re-filtration, which is more environmentally friendly and energy-saving.

[0040] As a specific technical solution of this embodiment, valves 41 are provided on the three ends of the three-way pipe 4, and regulating pipes 42 are provided on both ends of the three-way pipe 4 for connecting the water inlet joint 23 and the water collecting joint 202. The regulating pipe 42 is connected to the three-way pipe 4 through an adjustable bellows 43, and the interior of the three-way pipe 4 is also provided with a plurality of support rods 44 with one end extending into the interior of the regulating pipe 42.

[0041] In this embodiment, the adjustable bellows 43 is a telescopic tube commonly seen on the market, but its supporting effect is relatively poor, and a plurality of support rods 44 are provided, one end of the support rod 44 is fixed to the three-way pipe 4, and the other end extends to the interior of the adjusting pipe 42. This design allows the user to adjust the distance between the adjusting pipe 42 and the three-way pipe 4 while the plurality of support pipes can still maintain the coaxial stability between the adjusting pipe 42 and the three-way pipe 4, which facilitates adjustment according to the different distances between the two heat dissipation covers 2 during installation, thereby improving the versatility of the three-way pipe 4. The three ends of the three-way pipe 4 are all provided with a valve 41, which facilitates the user to independently shut off the water supply and water inlet maintenance of a single heat dissipation cover 2 without affecting the use of other heat dissipation covers 2.

[0042] As a specific technical solution of this embodiment, the water storage tank 3 includes a clean water tank 31 and a circulation box 32 arranged at the bottom of the clean water tank 31. The top and one side of the clean water tank 31 are respectively provided with a pump 1 33 and a pump 2 34 through a pump box. The input end of the pump 1 33 is connected to the clean water tank 31, and the output end of the pump 1 33 is connected to one of the water inlet joints 23 through a clean water pipe 35 and a three-way pipe 4. The input pipe of the pump 2 34 is connected to the circulation box 32, and the output end of the pump 2 34 is connected to the clean water tank 31. The circulation box 32 is connected to one of the water collecting joints 202 through a circulation pipe 36 and a three-way pipe 4. A water filling pipe 37 is provided on the top of the clean water tank 31, and a sewage pipe 38 is provided on one side of the circulation box 32.

[0043] In this embodiment, the circulation box 32 uses water to collect the water after spraying and cooling, so as to avoid the waste of water resources. The input end of the pump 2 34 is provided with a filter, which can filter the water inside the circulation box 32. The water inside the clean water tank 31 can be added with water through the water adding pipe 37, and the water inside the circulation box 32 can be discharged through the sewage pipe 38. The drainage pipe and the water adding pipe 37 need to be equipped with nut sealing covers for use later.

[0044] As a specific technical solution of this embodiment, the interior of the filter box 26 is provided with a flexible belt 264 located between two filter screens 261, the flexible belt 264 is flat, and a plurality of balls 265 are provided on the flexible belt 264, the balls 265 are made of metal, and the length of the flexible belt 264 is greater than the height of the filter box 26.

[0045] In this embodiment, the flexible belt 264 is made of leather, nylon and other materials, has soft characteristics and is flat, will not get tangled, and is more easily moved by the suction of the extension. When the fan 25 is started, one side of the fan 25 generates suction so that the flexible belt 264 is sucked and attached to one side of one of the filters 261. When the fan 25 is turned off, the flexible belt 264 loses the suction and resets and shakes, so that after the ball 265 hits the two filters 261 many times, the center of gravity remains stable and hangs between the two filters 261. When the ball 265 hits the filter 261, the dust intercepted on the filter 261 is shaken off to the conical surface, reducing the blockage of the filter 261, reducing the frequency of replacement and cleaning of the filter 261, and being more convenient to use. The ball 265 is made of metal but is hollow inside, and is easily attracted and moved by the fan 25.

[0046] As a specific technical solution of this embodiment, two conical surfaces are provided at the bottom of the inner wall of the filter box 26 and the two conical surfaces are respectively located at the bottom of two filter screens 261. A dust exhaust port 263 opposite to the middle position of the conical surface is provided at the bottom of the filter box 26. The dust exhaust port 263 is in a long strip shape. The width of the dust exhaust port 263 is smaller than the width of the filter screen 261. Handle grooves are provided at both ends of the filter screen 261.

[0047] In this embodiment, filter 1 261 can be pulled out from the interior of filter box 26 for cleaning through the handle groove. When filter 1 261 is pulled out, the dust on the conical surface is discharged through the dust outlet 263. The width of dust outlet 263 is smaller than the width of filter 1 261, so that when filter 1 261 is inside filter box 26, it can block dust outlet 263, thereby preventing air from entering filter box 26 through dust outlet 263. Filter 2 262 can block large particles or some garbage such as leaves. Filter 1 261 is used to further filter particles in the air, thereby preventing large particles of dust from entering the interior of heat sink 2 and adhering to heat sink 11 to affect the heat dissipation effect of heat sink 11.

[0048] As a specific technical solution of this embodiment, a plurality of exhaust holes and exhaust hole covers 201 corresponding to the exhaust holes are arranged on the top of the heat dissipation cover 2, a circle of the top of the exhaust holes is convex and a one-way exhaust valve is arranged inside the exhaust holes, the heat dissipation cover 2 is fixed to one side of the transformer body 1 by screws and a sealing ring is arranged between the heat dissipation cover 2 and the transformer body 1, and the filter box 26 is fixed to one side of the heat dissipation cover 2 by screws and a sealing ring is arranged between the filter box 26 and the heat dissipation cover 2.

[0049] In the present embodiment, the top of the exhaust hole is convex and a one-way exhaust valve is provided inside the exhaust hole. When used in conjunction with the exhaust hole cover 201, rainwater is prevented from entering the exhaust hole on rainy days. At the same time, the exhaust hole can only exhaust air in one direction and cannot take in air. The exhaust hole is close to one side of the transformer body 1 and is diagonally arranged with the fan 25, so that the air blown into the heat sink 2 by the fan 25 is in full contact with the heat sink 11, thereby ensuring the heat dissipation efficiency.

[0050] As a specific technical solution of this embodiment, a circle of water guide enclosure is provided on the outside of one side of the fan 25 extending to the inside of the air guide cover 24, the bottom of the air guide cover 24 is inclined and a water outlet 28 is provided at the lowest horizontal point, a force-bearing plate 27 is movably provided inside the air guide cover 24, a pressure plate 271 is provided at the bottom of the force-bearing plate 27, one end of the pressure plate 271 is rotatably connected to the bottom of the inner wall of the air guide cover 24, and a valve pad 272 is provided at the bottom of the other end of the pressure plate 271.

[0051] In the present embodiment, when water cooling is used for heat dissipation, when water droplets or water mist enter the interior of the air guide cover 24 through the ventilation holes, they come into contact with the inner wall of the air guide cover 24 and the air guide baffle 241. The setting of the water guide enclosure ensures that the water sliding down the inner wall of the air guide cover 24 will not contact the fan 25, but will slide down to the inner bottom of the water guide cover through the water guide enclosure, and finally flow into the inner bottom of the heat dissipation cover 2 through the water outlet 28 and flow into the interior of the circulation box 32 through the water collecting joint 202, the three-way pipe 4, and the circulation pipe 36 for reuse.

[0052] As a specific technical solution of this embodiment, the valve pad 272 is opposite to the water outlet 28, and a spring 273 is arranged on one side of the force-bearing plate 27. The end of the spring 273 away from the force-bearing plate 27 is connected to one side of the inner wall of the air guide cover 24. A rubber sheath movably connected to the outside of the spring 273 is also arranged between the force-bearing plate 27 and one side of the inner wall of the air guide cover 24. A baffle 29 located above the spring 273 is arranged on one side of the inner wall of the air guide cover 24.

[0053] In this embodiment, the design of the air guide baffle 241 can separate the wind blown out by the fan 25 into two parts, which are blown to the inside of the heat dissipation cover 2 from the upper and lower parts of the air guide baffle 241, respectively. With the arrangement of a plurality of ventilation holes, the wind delivered to the inside of the heat dissipation cover 2 is more uniform, and the hot air after dissipating heat at the bottom of the heat sink 11 will not dissipate heat again at the top of the heat sink 11. The heat is dissipated from one side of the heat sink 11, which is more suitable for use with narrower heat sinks 11, and the heat dissipation effect is better. Figure 8 When the fan 25 is not started, the spring 273 lifts the force plate 27 to drive the pressure plate 271 to lift up, so that the valve pad 272 is free from blocking the water outlet 28, see Fig. 9 When the fan 25 is started, the wind blown by the fan 25 presses the force-bearing plate 27, and the force-bearing plate 27 compresses the spring 273 and makes one end of the force-bearing plate 27 contact one end of the baffle 29. At the same time, the force-bearing plate 27 drives the pressure plate 271 to flip, so that the pressure plate 271 drives the valve pad 272 to block the water outlet 28, so that the air inside the air guide cover 24 can only enter the interior of the heat dissipation cover 2 through the ventilation hole.

[0054] To sum up, the transformer heat sink water-cooling and air-cooling integrated device detects the temperature value of the heat sink 11 through a temperature sensor and selects air cooling or water cooling for heat dissipation. Since water cooling has more serious energy consumption and energy loss, it is more appropriate to use air cooling when the heat dissipation requirement is not high. Both air cooling and water cooling are integrated into the heat dissipation cover 2. When used independently, they will not affect each other and can be used in conjunction with the three-way pipe 4, so that the heat dissipation covers 2 around the transformer body 1 can be closed independently for maintenance without affecting the use of other heat dissipation covers 2, and are more convenient to use.

[0055] It should be noted that, in this article, terms such as "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.
