Description

Technical Field

[0001] This invention belongs to the technical field of transformer radiators, specifically relating to a transformer radiator with internal fins fixedly attached. Background Technology

[0002] Transformers generate a lot of heat during operation. If heat is not dissipated in time, the temperature may rise, affecting the performance and lifespan of the transformer. Installing a radiator can increase the heat dissipation area, accelerate heat dissipation, and thus effectively control the temperature of the transformer and ensure its stable operation.

[0003] In existing transformer radiators, dust accumulation on the heat sink fins during heat dissipation can affect performance and effectiveness. Cleaning of the fin surface is necessary, but this is typically done manually, which is inefficient and yields poor results. Furthermore, dust accumulated at the base of the fins is often not thoroughly removed, further reducing heat dissipation. This issue has become a pressing problem for those in the field. Summary of the Invention

[0004] The purpose of this invention is to provide a transformer radiator with internal fins fixedly attached, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a transformer radiator with internal fins fixedly attached, comprising a transformer heat dissipation device, wherein the transformer heat dissipation device includes two manifolds, a bracket, two support plates, a plurality of cleaning cotton, a plurality of heat dissipation fins, and a cleaning mechanism; the cleaning mechanism includes two sliders, an undulating cavity, and an expansion joint, wherein the expansion joint is connected to an external hydraulic pump pipeline; each of the two manifolds includes a plurality of internal fins, an end cap, two through rods, and a plurality of connectors; the two manifolds are respectively fixedly installed on the upper and lower sides of the bracket, and the plurality of internal fins... The bracket is fixed to the end cap by two through rods, both of which are located inside the manifold. Several heat sinks are fixedly installed between the two manifolds by connectors. Slide grooves are provided on both the front and rear sides of the bracket, and two sliders are slidably connected in the slide grooves. Two support plates are fixed to the inner sides of the two sliders respectively. Several cleaning cottons are fixedly installed between the two support plates and are inserted between the heat sinks. The undulating cavity is fixedly installed on one side of the bottom of the bracket, and a hole is opened at the top. The telescopic joint is inserted into the hole, and its upper end is fixed to the slider, and its lower end is fixed to the inside of the undulating cavity.

[0006] The present invention further explains that the external hydraulic pump connected to the expansion joint is equipped with an adjustment system. The adjustment system is used by the operator to input a frequency and control the frequency of liquid injection and liquid extraction from the external hydraulic pump according to the frequency, thereby adjusting the frequency of cleaning the heat sink.

[0007] The present invention further illustrates that, one of the sliders is fixed with a pressing rod on one side, a through hole is provided above the undulating cavity, and a hydraulic rod is slidably connected in the through hole, and a hydraulic cavity is fixed at the bottom of the inner wall of the undulating cavity; a hydraulic plate is slidably connected to the inner wall of the hydraulic cavity, the hydraulic rod is fixedly connected to the hydraulic plate, the hydraulic plate is spring-connected to the bottom of the inner wall of the hydraulic cavity, a disc is fixed to the bottom of the telescopic joint, a spring spring is fixed to the bottom of the disc, an impact rod is fixed to the bottom of the spring spring, an impact cavity is fixed to the bottom of the inner wall of the undulating cavity, an impact plate is slidably connected to the inner wall of the impact cavity, and the upper surface of the impact plate is fixedly connected to the bottom of the impact rod.

[0008] The present invention further illustrates that two pipes are connected between the bottom of the hydraulic chamber and the top of the impact chamber, and the two pipes are an inlet pipe and an outlet pipe, respectively. Pressure valves are installed in both the inlet pipe and the outlet pipe; the bottom end of the extrusion rod and the upper end of the hydraulic rod are both spherical, and the extrusion rod contacts the hydraulic rod after moving downward.

[0009] The present invention further illustrates that a gear is installed on the bearing of the inner wall of the undulating cavity, and a plurality of tooth blocks are provided on one side of the hydraulic rod, which mesh with the gear through the plurality of tooth blocks; a pushing cavity is fixed on one side of the gear, a push-pull plate is slidably connected to the inner wall of the pushing cavity, a push-pull rod is fixed on the inner side of the push-pull plate, and a spring connects the push-pull plate and the inner wall of the pushing cavity; after the gear rotates, the push-pull rod contacts the telescopic joint.

[0010] The present invention further illustrates that there is a pipe connection between the outer side of the pushing cavity and the bottom of the impact cavity.

[0011] The present invention further illustrates that elastic cavities are attached to both the left and right sides of the disk, one of the elastic cavities is fixed to one side of the hydraulic cavity, and the other elastic cavity is fixed to the inner wall of the undulating cavity; both elastic cavities are elastic.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention controls the extension and retraction of the telescopic joint, thereby driving the cleaning cotton to move up and down. Repeating this operation cleans the heat sink, which is automated, efficient and convenient, and can always ensure the heat dissipation efficiency of the heat sink. Moreover, the frequency of the cleaning cotton moving up and down can be controlled, and the cleaning efficiency can be freely controlled. On the one hand, it can ensure the cleaning effect, and on the other hand, it can reduce the cleaning frequency when the amount of air dust is small, thereby reducing energy consumption and saving costs.

[0013] When the expansion joint shortens, the cleaning cotton scrapes the dust on the heat sink to the bottom, causing the cleaning cotton to move downwards quickly and generate an impact force. This force can knock the dust off the heat sink, preventing the dust from being unable to be fully scraped off the heat sink due to the high resistance of the dust and the low suction of the external hydraulic pump. This avoids dust accumulating at the bottom of the heat sink and reducing the heat dissipation effect, and ensures that the dust is fully scraped off every time the heat sink is cleaned.

[0014] During the dust cleaning process, the expansion joint vibrates. This vibration, along with the slider and support plate, causes the cleaning cotton to shake, dislodging dust from the cotton and residual dust from the heat sink, further improving the cleaning effect. Furthermore, when the external hydraulic pump draws liquid from the expansion joint, the disc is clamped by two elastic chambers, enhancing stability during operation and ensuring the impact plate remains stable. Simultaneously, the vibration of the expansion joint causes the disc to bounce left and right. The elastic force applied by the two chambers during this bounce provides cushioning, preventing excessive vibration that could damage the heat sink and thus protecting the transformer radiator.

[0023] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-6 The present invention provides a technical solution: a transformer radiator with internal fins fixedly attached, including a transformer heat dissipation device, which includes two current collectors 1, a bracket 2, two support plates 3, a number of cleaning cotton 4, a number of heat dissipation fins and a cleaning mechanism.

[0025] The cleaning mechanism includes two sliders 5, an undulating cavity 6, and a telescopic joint 61. The telescopic joint 61 is connected to an external hydraulic pump pipeline. Both manifolds 1 include several inner fins 11, end caps 12, two insert rods 13, and several connectors 14.

[0026] Two manifolds 1 are fixedly installed on the upper and lower sides of the bracket 2, respectively. Several inner fins 11 are fixed to the end caps 12 by two through rods 13 and are all located inside the manifolds 1. Several heat sinks are fixedly installed between the two manifolds 1 by connectors 14. Slide grooves are provided on the front and rear sides of the bracket 2, and two sliders 5 are slidably connected in the slide grooves. Two support plates 3 are fixed to the inner sides of the two sliders 5 respectively. Several cleaning cotton 4 are fixedly installed between the two support plates 3 and are inserted between the heat sinks. The undulating cavity 6 is fixedly installed on one side of the bottom of the bracket 2 and has a hole at the top. The expansion joint 61 is inserted into the hole and its upper end is fixed to the slider 5, and its lower end is fixed to the inside of the undulating cavity 6.

[0027] The heat sink increases the contact area between the fluid and the pipe wall through the inner fins inside the manifold 1, improving heat transfer efficiency and guiding the fluid to form turbulence within the manifold 1, thereby enhancing heat transfer. During the heat dissipation process, the cleaning cotton 4 is initially located at the upper end of the heat sink. Then, the external hydraulic pump operates, drawing out the liquid from the expansion joint 61, causing the expansion joint 61 to shorten. The expansion joint 61 drives the slider 5 to slide downward through the slide groove, thereby driving the cleaning cotton 4 downward through the support plate 3. The cleaning cotton 4 cleans the surface of the heat sink, scraping the dust on the heat sink to the bottom, thereby improving the heat dissipation efficiency of the heat sink. Afterward, the external hydraulic pump re-injects the liquid into the expansion joint 61, causing it to extend and reset, thereby driving the cleaning cotton 4 to reset. This operation is repeated to clean the heat sink. The automated cleaning process is efficient and convenient, and can ensure the heat dissipation efficiency of the heat sink at all times.

[0028] The external hydraulic pump connected to the expansion joint 61 is equipped with an adjustment system. The adjustment system is used by the operator to input the frequency and control the frequency of liquid injection and liquid extraction into the expansion joint 61 by the external hydraulic pump, thereby adjusting the frequency of cleaning the heat sink.

[0029] Operators can manually adjust the frequency of the external hydraulic pump drawing liquid from the telescopic joint 61 and injecting hydraulic pressure, thereby changing the frequency of the cleaning cotton 4 moving up and down, and freely controlling the cleaning efficiency. On the one hand, this ensures the cleaning effect, and on the other hand, it reduces the cleaning frequency when there is little dust in the air, thereby reducing energy consumption and saving costs.

[0030] One of the sliders 5 is fixed with a pressing rod 51 on one side, a through hole is opened above the undulating cavity 6, and a hydraulic rod 62 is slidably connected in the through hole. A hydraulic cavity 63 is fixed at the bottom of the inner wall of the undulating cavity 6.

[0031] A hydraulic plate 631 is slidably connected to the inner wall of the hydraulic chamber 63. A hydraulic rod 62 is fixedly connected to the hydraulic plate 631. A spring connects the hydraulic plate 631 to the bottom of the inner wall of the hydraulic chamber 63. A disc 611 is fixed to the bottom of the telescopic joint 61. A spring spring 612 is fixed to the bottom of the disc 611. An impact rod 613 is fixed to the bottom of the spring spring 612. An impact chamber 64 is fixed to the bottom of the inner wall of the undulating chamber 6. An impact plate 641 is slidably connected to the inner wall of the impact chamber 64. The upper surface of the impact plate 641 is fixedly connected to the bottom of the impact rod 613.

[0032] Two pipes are connected between the bottom of the hydraulic chamber 63 and the top of the impact chamber 64, and the two pipes are an inlet pipe and an outlet pipe, and a pressure valve 65 is installed in both the inlet pipe and the outlet pipe.

[0033] The bottom end of the extrusion rod 51 and the upper end of the hydraulic rod 62 are both spherical, and the extrusion rod 51 contacts the hydraulic rod 62 after moving downward.

[0034] When the telescopic joint 61 shortens, the cleaning cotton 4 scrapes the dust on the heat sink to the bottom. At the same time, the slider 5 moves to the bottom and drives the extrusion rod 51 to squeeze the hydraulic rod 62. The hydraulic rod 62 is forced to drive the hydraulic plate 631 to slide down along the inner wall of the hydraulic chamber 63. The spring is deformed by the force, and the hydraulic pressure below the hydraulic plate 631 is squeezed into the inlet pipe. After the pressure valve 65 reaches the pressure limit, it opens. The liquid quickly enters the impact chamber 64 through the inlet pipe. The liquid impacts the upper part of the impact plate 641. The impact plate 641 is subjected to the impact force, which causes the telescopic joint 61 to move down quickly as a whole, which causes the cleaning cotton 4 to move down quickly and generate an impact force. This can knock the dust scraped off the heat sink and prevent the dust from being fully scraped off the heat sink due to the large resistance of the dust and the low suction of the external hydraulic pump. This also prevents the dust from accumulating at the bottom of the heat sink and reducing the heat dissipation effect.

[0035] Then the telescopic joint 61 resets, causing the slide plate 5 to reset. The squeezing rod 51 disengages from the hydraulic rod 62, and the spring generates a reaction force, causing the hydraulic plate 631 to reset. During the reset process, the liquid in the impact chamber 64 is extracted through the liquid outlet pipe, thereby resetting it. This ensures that dust can be thoroughly scraped off each time the heat sink is cleaned.

[0036] Gear 66 is installed on the bearing inside the undulating cavity 6. Several tooth blocks are provided on one side of the hydraulic rod 62, and the tooth blocks mesh with the gear 66.

[0037] A push cavity 67 is fixed on one side of the gear 66. A push-pull plate 671 is slidably connected to the inner wall of the push cavity 67. A push-pull rod 672 is fixed on the inner side of the push-pull plate 671. The push-pull plate 671 and the inner wall of the push cavity 67 are connected by a spring. After the gear 66 rotates, the push-pull rod 672 contacts the telescopic joint 61.

[0038] When the hydraulic rod 62 moves downward, it meshes with the gear 66 through the toothed block, causing the gear 66 to rotate. The gear 66 drives the push-pull rod 672 to rotate around the center through the push chamber 67. When the push-pull rod 672 rotates to contact one side of the telescopic joint 61, the two squeeze each other, causing the telescopic joint 61 to shift within the hole. The spring spring 612 is deformed by force. After the hydraulic rod 62 returns to its original position, the gear 66 returns to its original position, and the push-pull rod 672 disengages from the telescopic joint 61. The spring spring 612 generates a reaction force to return to its original position, causing the telescopic joint 61 to shake. During the shaking process, the cleaning cotton 4 shakes through the slider 5 and the support plate 3, which can shake off the dust on the cleaning cotton 4 and the residual dust on the heat sink, further improving the cleaning effect.

[0039] A pipe connects the outer side of the pushing chamber 67 to the bottom of the impact chamber 64;

[0040] When the push-pull rod 672 contacts and squeezes against the telescopic joint 61, the push-pull rod 672 is subjected to force, causing the push-pull plate 671 to slide outward along the inner wall of the push chamber 67. The gas on one side of the push-pull plate 671 is squeezed and enters the bottom of the impact chamber 64 through the pipe. The gas generates an impact force, causing the impact plate 641 to be subjected to upward force, thereby enabling the pressure valve 65 in the liquid outlet pipe to open smoothly, facilitating the reset of the push plate 671, so that the cleaning cotton 4 can impact the scraped dust each time.

[0041] Both sides of the disc 611 are fitted with elastic cavities 68, one of which is fixed to one side of the hydraulic cavity 63, and the other is fixed to the inner wall of the undulating cavity 6.

[0042] Both elastic cavities 68 are elastic;

[0043] When the external hydraulic pump draws liquid from the telescopic joint 61, the disc 611 is clamped by the two elastic chambers 68, thereby improving the stability during operation and enabling the impact plate 641 to remain stable.

[0044] At the same time, when the expansion joint 61 shakes, it causes the disc 611 to bounce left and right. When the disc 611 bounces, the elastic force applied by the two elastic chambers 68 generates a buffer, preventing the entire device from vibrating and damaging the heat sink due to excessive bouncing amplitude, thus protecting the transformer heat sink.
