Description

Technical Field

[0001] The utility model relates to the technical field of wind power converter cabinets, in particular to an air-cooled heat dissipation device for a wind power converter cabinet. Background Art

[0002] When the wind power converter cabinet is installed inside the nacelle, the concentrated heat dissipation of the generator, pitch motor, yaw motor and other equipment in the nacelle often leads to excessively high ambient temperature inside the converter cabinet under high ambient temperature and long-term full-power load, which reduces the life and reliability of the components in the cabinet and causes the temperature protection relay to operate, causing the entire wind turbine to shut down, resulting in great economic losses.

[0003] During use, wind power converter cabinets currently usually use an air-cooled heat dissipation structure for heat dissipation. The air-cooled heat dissipation structure needs to be used in conjunction with a filter to block dust and impurities entering the cabinet to prevent them from affecting the use and life of components in the cabinet. However, long-term use will cause dust accumulation on the filter, which will lead to a significant reduction in the air intake, that is, the heat dissipation efficiency in the converter cabinet is poor, and the existing methods mostly require manual cleaning, which is less practical.

DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1

[0030] Reference Figure 1~Figure 4, which is the first embodiment of the utility model, and this embodiment provides an air-cooled heat dissipation device for a wind power converter cabinet, which can achieve the effect of ensuring the cabinet exhaust volume by side air intake when the filter screen is clogged with dust, thereby avoiding the cabinet heat dissipation effect from being affected. It includes an installation component 100, including a guide cover 101, a mounting plate 102 arranged on one side of the guide cover 101, a filter frame 103 arranged in the guide cover 101, a support frame 104 arranged in the guide cover 101, and a fan 105 arranged on one side of the support frame 104; a connecting component 200, including a connecting component 201 arranged on one side of the guide cover 101, a ventilation component 202 arranged on one side of the filter frame 103, and a negative pressure component 206 arranged on the side wall of the guide cover 101.

[0031] Specifically, the guide cover 101 is installed on the exhaust side of the converter through the mounting plate 102. The guide cover 101 guides the air flowing through the converter, which can increase the flow rate of the air flowing through the converter, thereby improving the heat dissipation efficiency of the converter in the cabinet. Figure 1 The guide cover 101 is provided with an exhaust channel on one side of the fan 105, and its diameter is smaller than the air intake side of the guide cover 101. Through the Bernoulli principle, it can assist in providing the wind speed when the air is discharged through the fan 105, accelerate the circulation speed of the air, and further assist in the heat dissipation and exhaust process of the inverter.

[0032] Furthermore, the connecting component 201 includes a connecting frame 201a fixedly connected to the side wall of the guide cover 101, a connecting groove 201b is provided in the connecting frame 201a, the connecting groove 201b connects the guide cover 101 and the mounting frame 202a, a collecting filter plate 201c is provided in the connecting groove 201b, and an air inlet frame 201d is fixedly connected to the inner wall of the guide cover 101; the ventilation component 202 includes a mounting frame 202a arranged on one side of the filter frame 103, an air duct 202b is fixedly connected to one side of the mounting frame 202a, an air inlet 202c is provided on the side wall of the air duct 202b, and the air inlet 202c is connected to the ventilation duct 202b, and the negative pressure component 206 includes a negative pressure groove 206a opened on one side of the guide cover 101, and the side wall of the guide cover 101 located at the negative pressure groove 206a is rotatably connected to a swing plate 206b.

[0033] The air inlet frame 201d is located on one side of the guide cover 101 and is provided with an air inlet slot. The air that is blocked by the dust on the filter frame 103 and cannot circulate normally enters the mounting frame 202a through the air inlet slot and the connecting slot 201b therein, and is finally discharged through the exhaust direction of the guide cover 101. The collecting filter plate 201c is located in the mounting frame 202a and can be used to collect dust in the air passing through the connecting slot 201b. The negative pressure slot 206a is as shown in FIG. Figure 1It is shown as an inclined groove inclined toward the mounting plate 102, wherein the swing plate 206b is in a closed state in the initial state, and its open state is adjusted with the adjustment of the air intake volume and the size of the negative pressure generated by the air circulation at the negative pressure groove 206a, which is used to control the air intake volume of the guide cover 101 by the size of the air negative pressure, and at the same time has the effect of supplementing the intake air for the guide cover 101. In addition, the negative pressure groove 206a is inclined toward the direction of the inverter, and under the guidance of the swing plate 206b in the open state, the external air can be sucked in and directed toward the direction of the inverter, which is used to assist in cooling and ventilating the inverter by sucking in relatively low-temperature external air.

[0034] When in use, the guide cover 101 is installed at the inverter through the mounting plate 102. At this time, the inverter is in the guide cover 101. The operation of the fan 105 and the guidance of the inhaled air by the guide cover 101 can guide the air passing through the inverter, and the air in the air-cooling is concentrated through the inverter to guide it to have a heat dissipation effect on the inverter, and then flows to the fan 105 through the filter frame 103, and finally discharged through the exhaust port of the guide cover 101. At this time, the air passing through the exhaust port of the guide cover 101 has a large difference in aperture size between the exhaust port and the air inlet 202c, so the air flow rate at the exhaust port is increased, providing a relatively large air flow rate for the dust accumulation on the filter screen of the filter frame 103 to prevent it from accumulating on it. The effect of dust accumulation on the filter is achieved, but there will still be a certain amount of dust accumulated on the filter during this process. At this time, as the dust accumulates, the air circulation at the filter will be affected. At this time, the air enters the connecting groove 201b through the air inlet groove of the air inlet frame 201d, and is connected to the exhaust of the guide cover 101 through the mounting frame 202a. At this time, as the dust on the filter continues to accumulate, the amount of air entering from the air inlet groove gradually increases, and at the same time, the amount of air passing through the filter gradually decreases, but the air discharged through the air inlet groove and the connecting groove 201b will keep the amount of air discharged through the fan 105 unchanged, thereby avoiding the problem that the amount of air discharged from the guide cover 101 is reduced and the heat dissipation process of the inverter is affected.

[0035] In summary, the air inlet slot and the connecting slot 201b on the side of the guide cover 101 can provide sufficient air discharge for the guide cover 101 when the filter is clogged with dust, thereby avoiding the problem that the exhaust volume of the guide cover 101 is affected and the heat dissipation process of the inverter is affected.

[0036] Example 2

[0037] Reference Figure 5~Figure 6, which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a cleaning component 204 of an air-cooled heat dissipation device of a wind power converter cabinet, which solves the problem that the filter needs to be manually cleaned after a large amount of dust accumulates, which affects the heat dissipation process of the converter. It includes a rotating shaft 203a that passes through a rotating connection mounting frame 202a, and a fan blade 203b is fixedly connected to the side wall of the rotating shaft 203a. The fan blade 203b is arranged in the air duct 202b. The cleaning component 204 includes a rotating frame 203a fixedly connected to the side wall of the rotating shaft 203a. 04a, an air inlet 204b is provided on one side of the rotating frame 204a, a connecting net 204c is provided on one side of the mounting frame 202a, the connecting net 204c is connected to the ventilation duct 202b, the air inlet 204b is connected to the ventilation duct 202b, the mounting assembly 205 includes a connecting block 205b arranged in the connecting groove 201b, a sliding groove 205a is provided on one side of the connecting block 205b, the collecting filter plate 201c is slidably connected to the sliding groove 205a, a mounting groove 205c is provided on one side of the connecting frame 201a, and the collecting filter plate 201c passes through the sliding connection mounting groove 205c.

[0038] Specifically, the rotating frame 204a is in sliding contact with the filter, and the direction of its air inlet 204b is consistent with the rotation direction of the rotating frame 204a. In addition, the connecting net 204c is in a connected state with the filter, and the rotating frame 204a is in sliding contact with the connecting net 204c, and the air inlet 204b is connected to the connecting net 204c, wherein the collecting filter plate 201c is located at the air inlet 202c of the connecting groove 201b to collect the dust cleaned on the filter.

[0039] During use, when dust accumulates on the filter, a large amount of air flows through the air inlet groove and the connecting groove 201b during the air circulation process. At this time, the air enters the air duct 202b through the air inlet port 204b, and then enters the connecting groove 201b through the ventilation pipe 202b and the air inlet groove. At this time, during the air circulation process, due to the eccentric entry and discharge process, that is, the air flows through the inner wall of the air duct 202b, this will drive the fan blades 203b in the air duct 202b to rotate, and then drive the rotation of the rotating shaft 203a, and at the same time drive the rotating frame 204a to rotate on the filter. At this time, the rotation of the rotating frame 204a cleans the dust accumulated on the filter. At this time, the dust on the filter is cleaned by the rotating plate 301e, and a part of it enters the air duct 202b through the connecting net 204c, and the other part flows out through the air inlet port 204b The air passes through the air duct 202b and then enters the connecting groove 201b through the ventilation pipe 202b and the air inlet groove, and is then blocked and collected by the collecting filter plate 201c in the connecting groove 201b. At this time, the collecting filter plate 201c can be slid out through the mounting groove 205c on the side wall of the mounting frame 202a, which is used for convenient cleaning and installation and disassembly of the dust collected on the collecting filter plate 201c. Compared with the cleaning of the filter screen at the filter frame 103, the process is more convenient and faster. When the dust on the filter frame 103 is cleaned by the rotating frame 204a, a large amount of air circulates through the filter screen on the filter frame 103, so that the air in the guide cover 101 maintains a normal circulation state. Then, the above process is repeated to achieve the effect of cleaning the dust on the filter screen without interfering with the air flow in the guide cover 101.

[0040] In summary, by driving the rotating frame 204a and the fan blades 203b, the filter on the filter frame 103 can be automatically cleaned, and at the same time, the flow rate of the air circulating in the guide cover 101 is not affected when the filter frame 103 is blocked.

[0041] Example 3

[0042] Reference Figure 7, which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides a blocking component 300 of an air-cooled heat dissipation device for a wind power converter cabinet, which solves the problem that dust accumulates in the filter holes of the filter screen and cannot be thoroughly cleaned by rotating the rotating plate 301e. It includes a connecting base 301a fixedly connected to one side of the filter frame 103, a guide rod 301b is fixedly connected to one side of the connecting base 301a, a side wall of the guide rod 301b is slidably connected to a movable sleeve 301c, a side wall of the movable sleeve 301c is fixedly connected to a rotating base 301d, and a rotating base One side of 301d is rotatably connected to a rotating plate 301e, one side of the rotating plate 301e is provided with a protrusion 301f, the propulsion assembly 302 includes a driving groove 302a opened on the side wall of the movable sleeve 301c, the side wall of the guide rod 301b is fixedly connected to a tooth plate 302b, the rotating base 301d is rotatably connected to a gear 302c, the gear 302c is meshed with the tooth plate 302b, the reset assembly 303 includes a connecting plate 303b fixedly connected to one end of the guide rod 301b, and the connecting plate 303b and the opposite side wall of the movable sleeve 301c are elastically connected with a reset spring 303a.

[0043] Specifically, the connecting base 301a is fixedly connected to the center position of the filter frame 103, and when the filter frame 103 is not blocked by dust, the rotating plate 301e is in a rotationally closed state. In addition, the rotating plate 301e and the gear 302c are coaxially connected and are in a synchronous rotation state, wherein the gear 302c passes through the driving groove 302a and engages with the tooth plate 302b. At the same time, the return spring 303a is in a contracted state when the filter plate is not blocked by dust, and it is in a maximum contracted state and is in a balanced state with the air thrust passing through the filter frame 103. At this time, the rotating plate 301e is in a rotationally closed state, i.e., a contracted state.

[0044] When in use, when the dust on the filter frame 103 gradually blocks the filter screen on the filter frame 103, the thrust of the air passing through the filter frame 103 on the movable sleeve 301c gradually decreases, and the return spring 303a gradually begins to return to the state, pushing the movable sleeve 301c to move toward the filter frame 103, and the gear 302c and the tooth plate 302b gradually mesh. When the gear 302c continues to move in the meshing state, the meshing of the gear 302c and the tooth plate 302b drives the gear 302c to rotate in the rotating base 301d, and drives the rotating plate 301e to gradually be in the state as shown in FIG. Figure 7301c is in the open state shown in the figure, and the movable sleeve 301c is close to the filter frame 103. Then, when the filter screen on the filter frame 103 is clogged with dust until the rotating frame 204a starts to rotate, the rotating plate 301e moves to fit with the filter frame 103 under the pushing action of the return spring 303a. Through the contact between the rotating plate 301e and the filter frame 103, the protrusion 301f fits with the filter hole on the filter screen correspondingly, and the dust in the filter hole of the filter screen is contacted and cleaned. At the same time, the contact resistance between the rotating plate 301e and the filter frame 103 is The fan blade 203b is blocked, which can provide a larger air circulation volume for the rotation of the fan blade 203b, and assist in cleaning the dust on the filter frame 103. As the dust on the filter screen on the filter frame 103 is cleaned, the air circulation volume through the filter frame 103 gradually increases, and the rotating plate 301e and the movable sleeve 301c are pushed to move. At this time, the gear 302c is engaged with the tooth plate 302b to drive the rotating plate 301e to rotate and reset. At this time, the reset spring 303a is compressed and stored to provide reset potential energy for the next cleaning of the dust on the filter frame 103.

[0045] In summary, by rotating the rotating plate 301e to open and close, the dust on the filter frame 103 can be assisted to be cleaned, and at the same time, the amount of air passing through the air inlet 204b can be increased to provide auxiliary obstruction of the air flow for the rotation of the rotating frame 204a, thereby assisting the cleaning of the dust on the filter frame 103 and processing the residual dust in the filter mesh holes, thereby further improving the efficiency of dust cleaning on the filter frame 103.
