The main components include: frequency converter, radiator support, radiator core body, cooling fan, cooling pipeline, cooling liquid, etc. The blockage of the surface of the radiator core body will have a significant impact on the heat dissipation efficiency of the radiator core body, so it is necessary to reduce the impact of blockage or other factors on the heat dissipation efficiency.
[0003] The structure of the adsorbed matter barrier tool for the converter radiator of the present scheme is to manufacture a certain distance of the heat dissipation cavity between the radiator support and the radiator core body, use a dust screen with smaller mesh number, and screen and block the dust and willow catkins around the cavity, so as to reduce the amount of attachments on the surface of the radiator core body.
[0004] The dust screen can play a certain barrier role, but it cannot be maintained in a plane due to strength factors, and the cooling fan will generate a large suction force when operating at high frequency, so the dust screen will be adsorbed from the middle to the radiator core body, resulting in the dust screen approaching zero. Therefore, it is necessary to design a adsorbed matter barrier tool for the wind generating set converter radiator. UTILITY MODEL CONTENTS
[0005] The first purpose of the utility model is to provide an adsorbed matter barrier tool for the wind generating set converter radiator, which can effectively solve the problem of reduced heat dissipation efficiency of the wind generating set converter radiator caused by the accumulation of adsorbed matter.
[0006] The second purpose of the utility model is to provide a wind generating set converter radiator.
[0007] The first purpose of the utility model is realized by the following technical scheme: a dust absorption blocking tool for a wind turbine generator system converter radiator, comprising a net frame, a dust screen, an upper adjusting support and a lower adjusting support; wherein the upper adjusting support and the lower adjusting support are respectively detachably installed on the upper and lower parts of the radiator support of the radiator, the net frame is detachably installed on the upper adjusting support and the lower adjusting support, and the inside of the net frame is attached to the radiator core by adjusting the upper and lower adjusting supports, the outside of the net frame is kept apart from the radiator core to ensure the relative distance between the dust screen and the radiator core, the two vertical edges of the outside of the net frame are formed with vertically opposite vertical sliding rails, and the bottom edge is formed with a groove for supporting the dust screen, the dust screen is inserted into the vertical sliding rails of the two vertical edges of the outside of the net frame and is limited in the groove by the dead weight, and is used for blocking the dust absorption material from blocking the radiator core.
[0008] Preferably, the net frame is a square frame matching the shape and size of the radiator core.
[0009] Preferably, the dust screen covers the practical surface of the side of the radiator core facing the dust screen.
[0010] Preferably, the dust screen is a square net, the four peripheral edges of which are fixed by pressing strips, and a handle is arranged at the top.
[0011] Preferably, the distance between the outside of the net frame and the radiator core is 200mm.
[0012] Preferably, the dust screen is an 80-mesh dust screen.
[0013] Preferably, the upper adjusting support and the lower adjusting support are angle irons.
[0014] Preferably, the upper adjusting support and the lower adjusting support are installed on the radiator support by bolts.
[0015] Preferably, the net frame is installed on the upper adjusting support and the lower adjusting support by bolts.
[0016] The second purpose of the utility model is realized by the following technical scheme: a wind turbine generator system converter radiator, comprising a plurality of the above-mentioned dust absorption blocking tools, and one dust absorption blocking tool is matched with one radiator core, and the radiator core is transversely arranged on the radiator support.
[0017] Compared with the prior art, the utility model has the following advantages and beneficial effects:
[0018] 1. The utility model has simple and reliable structure, is convenient to install, and has no requirement for the experience and operation proficiency of operators.
[0019] 2. This utility model adopts an external mechanical structure design of heat dissipation bracket fixed to the converter heat sink. The positioning holes are fixed at the original bolt hole positions, which increases the relative distance between the barrier surface and the heat dissipation core. In addition, the dustproof net covers the entire usable surface of the heat dissipation core, which greatly improves the heat dissipation efficiency of the heat sink.
[0020] 3. The main function of the mesh frame and the upper and lower adjustment brackets is to increase the relative distance between the adsorbent and the heat dissipation core, maximizing the heat dissipation contact surface. The main function of the dustproof mesh is to block the adsorbent and reduce the accumulation on the surface of the heat dissipation core. At different spacings, the force of the airflow generated by the cooling fan on the adsorbent varies. By starting the cooling fan and testing the corresponding airflow, the spacing range with the smaller adsorption force was obtained, which is approximately 200mm. If the mesh count of the dustproof mesh is too high, it will lead to poor ventilation and reduced heat exchange efficiency with the outside air. If it is too low, fine particles will not be blocked. Therefore, an 80-mesh dustproof mesh is used, which can block particles well without affecting the heat exchange efficiency. Attached Figure Description

[0024] The present invention will be further described below with reference to specific embodiments.
[0025] Example 1
[0026] like Figs. 1 to 3 As shown, this embodiment discloses an adsorption blocking fixture suitable for the radiator of a wind turbine generator converter, including a mesh frame 1, a dustproof net 2, an upper adjusting bracket 3, and a lower adjusting bracket 4. The upper adjusting bracket 3 and the lower adjusting bracket 4 are detachably mounted on the upper and lower parts of the radiator's heat dissipation bracket 5 by bolts. The mesh frame 1 is detachably mounted on the upper adjusting bracket 3 and the lower adjusting bracket 4 by bolts. By adjusting the upper adjusting bracket 3 and the lower adjusting bracket 4, the inner side of the mesh frame 1 is made to fit against the radiator's heat dissipation core 6. A gap is maintained between the outer side of the mesh frame 1 and the heat dissipation core 6 to ensure the relative distance between the dustproof net 2 and the heat dissipation core 6, maximizing the heat dissipation contact surface. Two opposing vertical slide rails 7 are formed on the outer two vertical sides of the mesh frame 1, and a groove 8 is formed on its bottom edge to support the dustproof net 2. The dustproof net 2 is inserted into the vertical slide rails 7 on the outer two vertical sides of the mesh frame 1 and is limited by its own weight in the groove 8, thus preventing adsorption from clogging the heat dissipation core 6.
[0027] Preferably, the frame 1 is a square frame matching the shape and size of the heat dissipation core 6; the dust screen 2 covers the practical surface of the side of the heat dissipation core 6 facing the dust screen 2 to block as many adsorbents as possible; the dust screen 2 is a square screen, the edges of which are fixed by the pressing strips 10, and the top of which is provided with the handle 9 to facilitate the workers to pull out the dust screen 2 from the frame 1 for replacement and cleaning; the upper adjusting support 3 and the lower adjusting support 4 are angle irons.
[0028] In the embodiment, the frame 1 and the upper adjusting support 3 and the lower adjusting support 4 mainly function to increase the relative distance between the adsorbents and the heat dissipation core 6 and increase the heat dissipation contact surface as much as possible; the dust screen 2 mainly functions to block the adsorbents and reduce the accumulation on the surface of the heat dissipation core 6; the wind force generated by the heat dissipation fan is different in the different intervals, and the interval with smaller adsorption force is about 200 mm by starting the heat dissipation fan and testing the corresponding wind force; the dust screen 2 with too high mesh number will cause poor ventilation and reduce the heat exchange efficiency with the external air, and the dust screen 2 with too low mesh number will not be able to block the fine particles, so the dust screen 2 with 80 mesh is adopted, which can better block the particles and will not affect the heat exchange efficiency.
[0029] During installation, the above tool is installed by two workers, the two workers cooperate to fix the upper adjusting support 3 and the lower adjusting support 4 to the heat dissipation support 5 by bolts without fastening, assemble the frame 1 to the upper adjusting support 3 and the lower adjusting support 4 by bolts according to the relevant requirements, after the above operation, one worker pushes the frame 1 towards the heat dissipation core 6, and the other worker fastens the bolts of the upper adjusting support 3, the lower adjusting support 4, the heat dissipation support 5 and the upper adjusting support 3, the lower adjusting support 4 and the frame 1, and after meeting the installation requirements, the worker inserts the dust screen 2 into the two vertical sliding rails 7 outside the frame 1, and after the wind turbine generator set is operated, the tool can be observed or cleaned regularly.
[0030] Embodiment 2
[0031] As shown in Fig. 3 the embodiment, the wind turbine generator set converter radiator comprises a plurality of adsorbent blocking tools of embodiment 1, and one adsorbent blocking tool is matched with one heat dissipation core 6, and the heat dissipation core 6 is transversely arranged on the heat dissipation support 5.
[0032] The above-mentioned embodiments are only the preferred embodiments of the utility model, and do not limit the implementation range of the utility model, so that any change made according to the shape and principle of the utility model should be covered in the protection range of the utility model.
