[0008] The present invention further describes that two pipes are connected between the bottom of the hydraulic chamber and the top of the impact chamber, and the two pipes are a liquid inlet pipe and a liquid outlet pipe, and pressure valves are provided in the liquid inlet pipe and the liquid 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.

At the same time, when the expansion joint shakes, it drives the disc to jump left and right. When the disc jumps, the elastic force applied by the two elastic chambers produces a buffer to prevent the entire device from vibrating and damaging the heat sink due to excessive jumping amplitude, thereby protecting the transformer radiator.

DETAILED DESCRIPTION

[0023] The following is a further non-limiting detailed description of the technical solution of the present invention in conjunction with the preferred embodiments and the accompanying drawings. 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.

[0024] See also Figure 1-6 The present invention provides a technical solution: a transformer radiator fixed with inner fins, including a transformer heat dissipation device, the transformer heat dissipation device includes two collecting pipes 1, a bracket 2, two support plates 3, a plurality of cleaning cottons 4, a plurality of heat sinks and a cleaning mechanism;

[0025] The cleaning mechanism includes two sliders 5, an undulating chamber 6 and a telescopic joint 61, the telescopic joint 61 is connected to the external hydraulic pump pipeline, and the two manifolds 1 each include a plurality of inner fins 11, an end cover 12, two interpenetrating rods 13 and a plurality of connectors 14;

[0026] Two headers 1 are fixedly installed on the upper and lower sides of the bracket 2, respectively. A plurality of inner fins 11 are fixed to the end cover 12 through two insertion rods 13 and are all arranged inside the header 1. A plurality of heat sinks are fixedly installed between the two headers 1 through a connector 14. Slide grooves are arranged on the front and rear sides of the bracket 2, and two sliders 5 are slidably connected in the slide grooves, respectively. Two support plates 3 are fixed to the inner sides of the two sliders 5, respectively. A plurality of cleaning cottons 4 are fixedly installed between the two support plates 3 and inserted between the heat sinks. The undulating cavity 6 is fixedly installed on one side of the bottom of the bracket 2, and a hole is opened on the top. The telescopic joint 61 is inserted in the hole, and the upper end is fixed to the slider 5, and the 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 tube wall through the internal fins in the collecting tube 1, improves the heat transfer efficiency, and guides the fluid to form turbulence in the collecting tube 1, thereby enhancing heat transfer. In the process of heat dissipation of the heat sink, the cleaning cotton 4 is located at the upper end of the heat sink in the initial state. Then the external hydraulic pump runs to extract the liquid in the telescopic joint 61, so that the telescopic joint 61 is shortened. The telescopic joint 61 drives the slider 5 to slide downward through the slide groove, thereby driving the cleaning cotton 4 to move downward through the support plate 3. The cleaning cotton 4 cleans the surface of the heat sink, and the dust on the heat sink is scraped to the bottom of the heat sink, thereby improving the heat dissipation efficiency of the heat sink. Then the external hydraulic pump re-injects the liquid into the telescopic joint 61 to make it extend and reset, thereby driving the cleaning cotton 4 to reset, and repeats the operation to clean the heat sink. The automatic cleaning is efficient and convenient, and the heat dissipation efficiency of the heat sink can be guaranteed at all times.

[0028] The external hydraulic pump connected to the expansion joint 61 is provided with a regulating system, and the regulating system is used for the operator to input a frequency, and according to the frequency, the external hydraulic pump is controlled to inject and extract the liquid in the expansion joint 61, thereby adjusting the frequency of cleaning the heat sink;

[0029] The operator can manually adjust the frequency of the external hydraulic pump to extract the liquid in the telescopic joint 61 and inject hydraulic pressure, so as to change the frequency of the cleaning cotton 4 moving up and down, and freely control the cleaning efficiency. On the one hand, it can ensure the cleaning effect, and on the other hand, it can reduce the cleaning frequency due to the small amount of dust in the air, thereby reducing energy consumption and saving costs.

[0030] An extrusion rod 51 is fixed to one side of one of the sliders 5, a through hole is opened above the ups and downs cavity 6, and a hydraulic rod 62 is slidably connected in the through hole, and a hydraulic cavity 63 is fixed to the bottom of the inner wall of the ups and downs cavity 6;

[0031] The inner wall of the hydraulic chamber 63 is slidably connected with a hydraulic plate 631, the hydraulic rod 62 is fixedly connected to the hydraulic plate 631, the hydraulic plate 631 is spring-connected to the bottom of the inner wall of the hydraulic chamber 63, a disc 611 is fixed to the bottom end of the telescopic joint 61, an elastic spring 612 is fixed to the bottom end of the disc 611, an impact rod 613 is fixed to the bottom end of the elastic 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, and the upper surface of the impact plate 641 is fixedly connected to the bottom end 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 a liquid inlet pipe and a liquid outlet pipe, and pressure valves 65 are arranged in the liquid inlet pipe and the liquid 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 is shortened so that the cleaning cotton 4 scrapes the dust on the heat sink to the bottom, the slider 5 moves to the bottom at the same time and drives the squeezing rod 51 to squeeze the hydraulic rod 62. The hydraulic rod 62 is forced to drive the hydraulic plate 631 to slide downward 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 liquid inlet pipe. The pressure valve 65 opens after reaching the pressure limit, and the liquid quickly enters the impact chamber 64 through the liquid inlet pipe. The liquid impacts the top of the impact plate 641. The impact plate 641 is subjected to the impact force, so that the telescopic joint 61 moves downward rapidly as a whole, thereby causing the cleaning cotton 4 to move downward rapidly, generating an impact force, which can impact the dust scraped from the heat sink to the lower heat sink, thereby preventing the dust from being fully scraped off the heat sink due to the large resistance of the dust and the low suction force of the external hydraulic pump, thereby preventing the dust from accumulating at the bottom of the heat sink and reducing the heat dissipation effect.

[0035] Afterwards, the telescopic joint 61 is reset, so that the slide plate 5 is reset, the extrusion rod 51 is out of contact with the hydraulic rod 62, and the spring generates a reaction force to reset the hydraulic plate 631. During the reset process, the liquid in the impact cavity 64 is pumped out through the liquid outlet pipe to reset it, so that the dust can be fully scraped off each time the heat sink is cleaned.

[0036] The inner wall bearing of the undulating chamber 6 is provided with a gear 66, and one side of the hydraulic rod 62 is provided with a plurality of tooth blocks, which mesh with the gear 66 through the plurality of tooth blocks;

[0037] A push cavity 67 is fixed to one side of the gear 66, and a push-pull plate 671 is slidably connected to the inner wall of the push cavity 67. A push-pull rod 672 is fixed to the inner side of the push-pull plate 671. The push-pull plate 671 is connected to the inner wall of the push cavity 67 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 tooth block, driving 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 are squeezed, causing the telescopic joint 61 to shift in the hole, and the elastic spring 612 is deformed under force. After that, after the hydraulic rod 62 is reset, the gear 66 is reset, the push-pull rod 672 is disengaged from the telescopic joint 61, and the elastic spring 612 generates a reaction force to reset, thereby causing the telescopic joint 61 to shake. During the shaking process, the cleaning cotton 4 is driven to shake through the slider 5 and the support plate 3, so that dust on the cleaning cotton 4 and residual dust on the heat sink can be shaken off, further improving the cleaning effect.

[0039] The outer side of the pushing chamber 67 is connected to the bottom of the impact chamber 64 by a pipeline;

[0040] When the push-pull rod 672 contacts and squeezes the telescopic joint 61, the push-pull rod 672 is subjected to force to make the push-pull plate 671 slide outward along the inner wall of the push chamber 67, and the gas on one side of the push-pull plate 671 is squeezed into the bottom of the impact chamber 64 through the pipeline. The gas generates an impact force to make the impact plate 641 subject to upward force, so that the pressure valve 65 in the liquid outlet pipe can be opened smoothly, which is convenient for the resetting of the push plate 671, so that each time the cleaning cotton 4 is cleaned, it can impact the scraped dust.

[0041] Elastic cavities 68 are attached to both left and right sides of the disc 611, one of the elastic cavities 68 is fixed to one side of the hydraulic cavity 63, and the other elastic cavity 68 is fixed to the inner wall of the undulating cavity 6;

[0042] Both elastic chambers 68 are elastic;

[0043] When the external hydraulic pump extracts the liquid in the telescopic joint 61, the disc 611 is clamped by the two elastic chambers 68, thereby improving the stability during the working process, so that the impact plate 641 can remain stable;

[0044] At the same time, when the expansion joint 61 shakes, the disc 611 is driven to jump left and right. When the disc 611 jumps, the elastic force applied by the two elastic chambers 68 produces a buffer to prevent the entire device from vibrating too much and damaging the heat sink, thereby protecting the transformer radiator.
