Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor equipment, and more specifically, to a thyristor mounting structure. Background Art

[0002] Polysilicon, as an important semiconductor material, has been widely used in the fields of electronics, solar energy, etc. In previous years, with the development of the semiconductor industry, the market demand for polysilicon has increased year by year, and the industry scale has also been continuously expanding. With more production enterprises entering this industry, the industry competition has intensified, which also forces each enterprise to continuously improve the process and technology, reduce costs while improving production capacity and quality. In addition to the need for production enterprises to continuously upgrade the polysilicon production process, the supporting equipment also needs to be continuously optimized and upgraded to better meet the production and maintenance requirements. Among them, the thyristor (silicon controlled rectifier), as a key component in the polysilicon production process, is installed in the power distribution cabinet (power regulation cabinet) of the polysilicon reduction furnace, and its installation method will determine its maintenance convenience.

[0003] Currently, the commonly used thyristor installation method is to clamp the thyristor between the water-cooled package and the water-cooled aluminum row through a clamping mechanism. Through the clamping and release of the clamping mechanism, the fixing and replacement maintenance of the thyristor are completed;

[0004] When maintaining or replacing the thyristor, it is necessary to release the clamping mechanism. At this time, there is no directly fixedly connected device between the water-cooled package and the water-cooled aluminum row. It is necessary for the maintenance personnel to hold the water-cooled package with one hand all the time to ensure that the water-cooled package does not fall, and at the same time use the other hand to maintain or replace the thyristor. In the compact space of the power cabinet, the maintenance is not convenient and there are great potential safety hazards.

[0005] In summary, how to provide a thyristor mounting structure that can avoid the water-cooled package from falling during the replacement of the thyristor is an urgent problem to be solved by those skilled in the art at present. Summary of the Utility Model

[0035] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0036] The core of the present utility model is to provide a thyristor installation structure. By adding a limiting mechanism between the water-cooled package and the insulating baffle, when the clamping mechanism fails, the water-cooled package can still have a relatively stable relative position relationship with the water-cooled aluminum row, will not fall and be damaged, and is convenient for replacing and maintaining the thyristor with one hand in a narrow space.

[0037] Please refer to Figures 1 - 4 , a thyristor installation structure, including a water-cooled aluminum row 1 and a water-cooled package 3, which are used to abut against the thyristor 2 from both sides. Two groups of parallel pull rods 8 are arranged on the surface of the water-cooled aluminum row 1, and the water-cooled package 3 is arranged between the two groups of pull rods 8;

[0038] An insulating baffle 4 is slidably arranged on the pull rod 8, and the insulating baffle 4 abuts against the side of the water-cooled package 3 away from the water-cooled aluminum row 1;

[0039] A clamping mechanism 10 is arranged at the end of the pull rod 8, which is used to force the insulating baffle 4 to approach the water-cooled aluminum row 1;

[0040] A limiting mechanism is arranged between the water-cooled package 3 and the insulating baffle 4, which is used to limit the displacement of the water-cooled package 3 on the contact surface with the insulating baffle 4;

[0041] During use, the water-cooled aluminum row 1 is fixed to the distribution box, then the insulating baffle 4 and the clamping mechanism 10 are assembled, then the water-cooled package 3 and the thyristor 2 are installed, and finally the clamping mechanism 10 is clamped to complete the operation;

[0042] The thyristor 2 is clamped from both sides by the water-cooled aluminum bar 1 and the water-cooled pack 3 to ensure its stability and heat dissipation capacity;

[0043] When performing maintenance on the thyristor 2, the clamping mechanism 10 is released and the thyristor 2 is taken out;

[0044] At the same time, a limiting mechanism is added between the water-cooling pack 3 and the insulating baffle 4, so that the insulating baffle 4 and the water-cooling pack 3 have a relatively stable relative position relationship when they are in a non-clamped state. The insulating baffle 4 is slidably installed with the pull rod 8, so the water-cooling pack 3 is also restricted by the pull rod 8 and will not fall naturally. This makes it unnecessary to lift the water-cooling pack 3 by hand when installing or replacing the thyristor 2 to avoid it from falling and being damaged.

[0045] In some embodiments, the clamping mechanism 10 adopts an inclined-lever type clamping mechanism, for example, a disc is rotatably provided at the end of the pull rod 8, and the contact surface between the disc and the insulating baffle 4 is a wedge-shaped surface. When the disc rotates, the insulating baffle 4 can be pushed away from the end of the pull rod 8, thereby making the insulating baffle 4 close to the water-cooled aluminum row 1, and clamping the water-cooling package 3 and the thyristor 2;

[0046] In some embodiments, a hinged lever clamping mechanism is used, such as a handle and a long rod are hinged at the end of the pull rod 8, a short rod is connected between the handle and the middle position of the long rod, both ends of the short rod are connected in a hinged manner, and a clamping piece abutting against the insulating baffle 4 is provided at the free end of the long rod. When the clamping mechanism 10 is in a clamping state, the handle and the short rod axis overlap, and the handle is perpendicular to the long rod axis. At this time, the clamping mechanism 10 is in a self-locking state, which can also ensure that the water cooling pack 3 and the thyristor 2 are in a clamping state;

[0047] The limiting mechanism uses screws, rivets, etc. to fix the water-cooling pack 3 and the insulating baffle 4. However, when the water-cooling pack 3 needs to be repaired, the insulating baffle 4 needs to be removed together. Therefore, in some embodiments, a plurality of groups of pins are set on the surface of the insulating baffle 4, and pin holes are set at corresponding positions of the water-cooling pack 3. The relative positioning of the pins and the pin holes is utilized to achieve the relative limitation of the two. When the stroke released by the clamping mechanism 10 is small, that is, the pin cannot be completely detached from the water-cooling pack 3, the limiting mechanism can effectively ensure the relative position stability of the insulating baffle 4 and the water-cooling pack 3.

[0048] In some embodiments, Figure 1 and Figure 2 As shown, the clamping mechanism 10 comprises:

[0049] The pressing plate 6 is slidably mounted on the pull rod 8, and a threaded hole is provided on the surface of the pressing plate 6;

[0050] The adjusting bolt 7 is threadedly connected to the threaded hole, and its end abuts against the side of the insulating baffle 4 away from the water-cooling package 3;

[0051] The locking nut 9 is fixedly connected to the free end of the pull rod 8 by threaded connection to prevent the pressing plate 6 and the insulating baffle 4 from detaching from the pull rod 8;

[0052] By using the cooperation of the adjusting bolt 7 and the internal threaded hole of the pressing plate 6, the clamping force of the clamping mechanism 10 can be adjusted by rotating the adjusting bolt 7, so as to be suitable for the quick replacement and maintenance of water-cooling packages 3 and thyristors 2 of different specifications.

[0053] In some embodiments, as Figure 2 shown, a pressing cover plate 5 is rotatably arranged at the end of the adjusting bolt 7. The pressing cover plate 5 abuts against the side of the insulating baffle 4 away from the water-cooling package 3, and the contact area between the pressing cover plate 5 and the insulating baffle 4 is larger than the contact area of the end of the adjusting bolt 7 for contact;

[0054] The pressing cover plate 5 is arranged at the end of the adjusting bolt 7, which increases the contact area between the adjusting bolt 7 and the insulating baffle 4, avoiding the damage of the insulating baffle 4 caused by the over-concentration of the acting force. At the same time, when the pressing cover plate 5 and the adjusting bolt 7 are rotatably installed, when the clamping mechanism 10 is released, the pressing cover plate 5 will not detach from the adjusting bolt 7, avoiding the maintenance difficulty caused by the dropping of the pressing cover plate 5 during the maintenance in the distribution box with a narrow space.

[0055] In some embodiments, the water-cooling package 3 is of an L-shaped structure. The vertical wall of the water-cooling package 3 close to the thyristor 2 abuts against the end face of the thyristor 2, and the lower surface of the horizontal wall of the water-cooling package 3 abuts against the upper surface of the insulating baffle 4 and / or the water-cooling aluminum row 1;

[0056] As Figure 3 shown, through the L-shaped design of the water-cooling package 3, the horizontal wall is hung on the upper end of the insulating baffle 4, so that when the clamping mechanism 10 is released, the water-cooling package 3 still will not fall, without the need to hold it by hand, and the water-cooling package 3 can be pulled out from above, facilitating the maintenance and replacement of the water-cooling package 3;

[0057] At the same time, the right vertical wall of the water-cooling package 3 is the first working surface 301, which abuts against the thyristor 2 for the heat dissipation of the thyristor 2. The upper surface of the horizontal wall of the water-cooling package 3 can also be used as the second working surface 302, which abuts against other components to be heat-dissipated for heat dissipation, that is, the effective working area of the water-cooling package 3 is increased.

[0058] In some embodiments, as Figure 3 shown, a limiting groove 303 is arranged at one end of the lower surface of the horizontal wall of the water-cooling package 3 close to the vertical wall, and the upper edge of the insulating baffle 4 is clamped in the limiting groove 303;

[0059] By providing a limiting groove 303 on the lower surface of the horizontal wall of the water-cooling package 3 and fitting and installing the insulating baffle 4 with the limiting groove 303, when the insulating baffle 4 moves, it can drive the water-cooling package 3 to move synchronously, avoiding the problem that the insulating baffle 4 slides out of the coverage range of the horizontal wall of the water-cooling package 3 and causing the water-cooling package 3 to fall off.

[0060] In some embodiments, as Figure 4 shown, both ends of the limiting groove 303 are of a closed structure, and a snap groove 304 is provided inside the closed structure;

[0061] Both ends of the upper edge of the insulating baffle 4 are provided with snaps 401, and the snaps 401 can be snap-fitted into the snap grooves 304;

[0062] By providing the snap groove 304 and combining it with the snap 401 of the insulating baffle 4, the relative fixation of the insulating baffle 4 and the water-cooling package 3 is realized. When the clamping mechanism 10 operates, the water-cooling package 3 can move together with the insulating baffle 4, and when the clamping mechanism 10 is released, the water-cooling package 3 can still be relatively fixed to the insulating baffle 4;

[0063] When it is necessary to replace the water-cooling package 3, just disengage the snap 401 from the snap groove 304, and the water-cooling package 3 can be withdrawn from above, realizing the separation of the water-cooling package 3 and the insulating baffle 4.

[0064] In some embodiments, a process seam 402 is provided at a position on the upper end of the insulating baffle 4 close to the snap 401. When the two sides of the insulating baffle 4 are pressed, the process seam 402 can be squeezed, causing the snaps 401 on both sides to retract inward, thereby disengaging from the snap grooves 304;

[0065] As Figure 4 shown, by providing the process seam 402, a clearance space is provided behind the snap 401. When the snap 401 is squeezed from the side, it can retract backward, thus facilitating the separation from the snap groove 304, and being suitable for operation in a narrow distribution box.

[0066] In some embodiments, as Figure 1 shown, threaded holes are provided on the upper surface of the horizontal wall of the water-cooling package 3 for connecting the workpiece to be cooled located on the upper surface of the horizontal wall of the water-cooling package 3;

[0067] The top of the L-shaped water-cooling package 3 can also be installed with the workpiece to be cooled. The workpiece is locked to the top surface of the water-cooling package 3 through bolts, making them fully contact and effectively dissipating heat.

[0068] In some embodiments, through holes are provided on the surface of the water-cooled aluminum row 1, the pull rod 8 passes through the through holes, and nuts are provided at both ends of the through holes for fixing the pull rod 8 to the water-cooled aluminum row 1 through threaded connection;

[0069] Through the pull rod 8 of this design, thyristors 2, as well as the water-cooled packages 3 and clamping mechanisms 10 for clamping the thyristors 2, can be arranged on both sides of the water-cooled aluminum row 1, thereby improving the utilization rate of the water-cooled aluminum row 1.

[0070] In some embodiments, grooves are respectively provided on both side surfaces of the water-cooled aluminum row 1 for accommodating the thyristors 2 and restricting the displacement of the thyristors 2 along their contact surfaces with the water-cooled aluminum row 1.

[0071] When designing the water-cooled aluminum row 1, the installation positions of the thyristors 2 are defined by setting grooves on its surface. And during assembly, there is no need to continuously hold up the thyristors 2 by hand, avoiding pinching hands.

[0072] However, it should be noted that the groove depth is less than the thickness of the thyristor 2, and the groove shape is the same as the cross-sectional shape of the thyristor 2. Even more, the center line of the groove can overlap with the axis of the adjusting bolt 7, so that when the thyristor 2 is clamped, the overall force is uniform and the clamping is stable.

[0073] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. The same or similar parts among the embodiments can be referred to each other.

[0074] The above has introduced the thyristor installation structure provided by the present utility model in detail. Specific examples are used herein to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
