Technical Field
[0001] This invention belongs to the field of heat exchanger ventilation technology, and relates to a heat exchanger ventilation flow equalization device and method. Background Technology
[0002] A heat exchanger exchanges heat between cold air outside and the medium inside, causing the steam inside to condense or the temperature of the medium to decrease. Heat exchangers that condense steam are called air-cooled condensers, and those that decrease the temperature of the medium are called air-cooled radiators. Air-cooled condensers and air-cooled radiators are crucial equipment at the cold end of thermal and nuclear power plants. The better the uniformity of the airflow entering the heat exchanger, the higher the overall cooling efficiency.
[0003] The airflow outlet of the mechanical or natural ventilation duct supplying air to the heat exchanger is upward, while the airflow inlet is horizontal. The airflow direction turns from horizontal to vertical. For vertically arranged heat exchangers, the airflow volume is large at the top and decreases towards the bottom. For horizontally arranged heat exchangers, the airflow volume is large on the outside and decreases towards the inside. As the scale of thermal and nuclear power plant units increases, the height of heat exchanger installations also increases, and the unevenness becomes more and more significant. To integrate various heat dissipation needs, heat exchangers with different functions are combined and arranged in a single air supply facility, which can save investment and space. However, different functions of heat exchangers require different air volumes, resulting in an air supply mismatch problem. Summary of the Invention

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.
[0020] It should be noted that the terms "first," "second," etc., in the specification and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0021] The present invention will now be described in further detail with reference to the accompanying drawings: Example 1: See Figure 1 This embodiment discloses a heat exchanger ventilation and flow equalization device, including: a support frame 11, a plurality of axial sliding parts 12, a plurality of flow guide panels 16, a first locking part and an angle adjustment part 13; Define the direction of movement of the axial sliding part 12 along the support frame 11 as the first direction AB; The support frame 11 is the main support component, providing stable structural support for the entire ventilation and flow equalization device of the heat exchanger 1.
[0022] In this embodiment of the invention, the support frame 11 includes two parallel distance adjustment shafts 6, and the axial sliding part 12 slidably connects the two distance adjustment shafts 6.
[0023] In this embodiment of the invention, the support frame 11 also includes a base, and two distance adjustment shafts 6 are fixedly mounted on the base to further improve the stability of the device.
[0024] Several axial sliding parts 12 are slidably connected to the support frame 11 and can slide along the first direction AB, so that the guide panel 16 connected to the axial sliding parts 12 can be adjusted in position within a certain range. According to the actual size, layout and airflow distribution characteristics of the heat exchanger 1, the position of the guide panel 16 can be flexibly changed, thereby better adapting to the airflow guidance requirements under different operating conditions and improving the versatility and adaptability of the device.
[0025] The first locking part is used to fix the axial sliding part 12 on the support frame 11 after the axial sliding part 12 is adjusted to the correct position. After the axial sliding part 12 is adjusted to the appropriate position, the first locking part can fix the axial sliding part 12 on the support frame 11, ensuring the stability of the position of the guide panel 16 and ensuring the reliability of the airflow guiding effect.
[0026] In this embodiment of the invention, the axial sliding part 12 includes a plane angle adjusting shaft 7 and two first sleeves 14. The two first sleeves 14 are fixedly connected to the plane angle adjusting shaft 7, and each first sleeve 14 is slidably sleeved on one of the distance adjusting shafts 6.
[0027] In this embodiment of the invention, the first locking part includes a first positioning pin, a plurality of first positioning holes formed on the distance adjustment shaft 6, and a second positioning hole formed on the first sleeve 14. The first positioning pin passes through both the first positioning hole and the second positioning hole. When the position of the guide panel 16 needs to be adjusted, the first positioning pin is pulled out, and the first sleeve 14 can slide freely on the distance adjustment shaft 6. After the position of the guide panel 16 is adjusted to the correct position, the first positioning pin is inserted into the first positioning hole and the second positioning hole to achieve a fixed connection between the first sleeve 14 and the distance adjustment shaft 6.
[0028] The airflow guide panel 16 is rotatably connected to the axial sliding part 12, facilitating the adjustment of the angle of the airflow guide panel 16. This changes the direction of airflow, allowing cold air to pass through the heat exchanger 1 more evenly, effectively improving the problem of uneven airflow in the heat exchanger 1 and increasing cooling efficiency. Simultaneously, combined with the sliding function of the axial sliding part 12, the position and angle of the airflow guide panel 16 can be adjusted in multiple dimensions, further enhancing the ability to control airflow.
[0029] Angle adjustment unit 13 is connected to the air guide panel 16. The angle adjustment unit 13 is used to adjust the angle of the air guide panel 16. By precisely adjusting the angle of the air guide panel 16, the best airflow guiding effect can be achieved, thereby further improving the cooling efficiency of the heat exchanger 1.
[0030] In this embodiment of the invention, the flow guiding panel 16 includes a plurality of first flow guiding panels 9 and a plurality of second flow guiding panels 10, wherein the first flow guiding panels 9 and the second flow guiding panels 10 are arranged alternately. Both the first flow guide panel 9 and the second flow guide panel 10 include a plurality of spaced movable plates 4. The projection of the movable plates 4 of the first flow guide panel 9 on the first direction AB completely blocks the gap between the movable plates 4 of the second flow guide panel 10. In this embodiment of the invention, a certain gap is left between the first guide panel 9 and the second guide panel 10 to allow limited flow in the space on both sides of the heat exchanger ventilation equalization device, that is, to guide the airflow smoothly into the heat exchanger and automatically balance the pressure difference. The angle between the first guide panel 9 and the second guide panel 10 is adjustable, and the first guide panel 9 and the second guide panel 10 can be parallel to each other or have a certain angle, which helps to guide the direction of the airflow and reduce the dead angle of the heat exchanger ventilation. Adjacent first guide panels 9 and second guide panels 10 are grouped together, and several groups are arranged in the height direction of the heat exchanger. When the air inlet channels between the first guide panel 9 and the second guide panel 10 need to be completely isolated, the planar distance between the first guide panel 9 and the second guide panel 10 can be adjusted to the minimum, so that the first guide panel 9 and the second guide panel 10 are staggered and closed, thus achieving isolation of the air inlet channels between the groups. When the heat exchanger demand of each group of heat exchangers is different and the air inlet volume needs to be adapted, the angle between the plane of the first guide panel 9 and the second guide panel 10 and the heat exchanger can be adjusted. The heat exchanger with a large heat exchange capacity can increase the air inlet area, and the heat exchanger with a small heat exchange capacity can decrease the air inlet area.
[0031] In this embodiment, the edge of the movable layer 4 is provided with a raised baffle 17. When the planar distance between the first guide panel 9 and the second guide panel 10 in the same group is adjusted to the minimum, the movable layer 4 of the first guide panel 9 and the second guide panel 10 are interlocked by the raised baffle 17, so that the first guide panel 9 and the second guide panel 10 are staggered and closed, thereby achieving isolation of the air intake channels between each group.
[0032] See Figure 5 and Figure 6 In this embodiment, both the first guide panel 9 and the second guide panel 10 include a guide frame 5, a first connecting rod 18, and a power unit 22. A plurality of the layer movable pieces 4 are rotatably connected to the guide frame 5, and the plurality of the layer movable pieces 4 are movably connected to the first connecting rod 18. The power unit 22 is fixedly connected to the guide frame 5. The output end of the power unit 22 is connected to a transmission rod 19 through a transmission device. The transmission rod 19 is rotatably connected to the guide frame 5. A second connecting rod 20 is fixedly connected to the transmission rod 19. A third connecting rod 21 is movably connected to the second connecting rod 20. The third connecting rod 21 is movably connected to the first connecting rod 18.
[0033] In actual operation, the output end of the power unit 22 drives the transmission rod 19 to rotate through the transmission device. The transmission rod 19 synchronously drives the second connecting rod 20 to rotate. The second connecting rod 20 drives the first connecting rod 18 away from or near the flow guide frame 5 through the third connecting rod 21. When the first connecting rod 18 moves away from or near the flow guide frame 5, it drives the layer movable plate 4 to rotate, thereby adjusting the angle of the layer movable plate 4, guiding the direction of airflow, and reducing the dead angle of heat exchanger ventilation.
[0034] Preferably, the shape of the flow guide frame 5 is determined according to the shape of the heat exchanger 1, and the flow guide frame 5 can be triangular, fan-shaped, rectangular, etc. See also Figure 1 and Figure 2 The flow guide frame 5 is triangular in shape, see [reference]. Figure 5 and Figure 6 The flow guide frame 5 is rectangular in shape.
[0035] In this embodiment of the invention, the angle adjustment part 13 includes a movable plate connecting rod 3, an end limiting rod 8, and a second locking part. The flow guide panel 16 is connected to the end limiting rod 8 through the movable plate connecting rod 3. The movable plate connecting rod 3 is movably connected to a second sleeve 15. The second sleeve 15 is slidably sleeved on the end limiting rod 8. The second sleeve 15 is detachably and fixedly connected to the end limiting rod 8 through the second locking part.
[0036] During the angle adjustment of the flow guide panel 16, the second locking part is opened, allowing the second sleeve 15 to slide freely on the end limiting rod 8. After all the flow guide panels 16 are adjusted to the correct angle, the second locking part secures the second sleeve 15 to the end limiting rod 8, completing the angle adjustment of the flow guide panel 16. During the angle adjustment of the flow guide panel 16, the position and angle of the end limiting rod 8 change synchronously, and the end limiting rod 8 can move synchronously in the first direction AB and the second direction CD.
[0037] In this embodiment of the invention, the second locking part includes a second positioning pin, a plurality of third positioning holes formed on the end limiting rod 8, and a fourth positioning hole formed on the second sleeve 15, wherein the second positioning pin passes through both the third positioning holes and the fourth positioning hole.
[0038] During the angle adjustment of the flow guide panel 16, the second positioning pin is pulled out from the third and fourth positioning holes, and the second sleeve 15 can slide freely on the end limiting rod 8. After all the angles of the flow guide panels 16 are adjusted to the correct position, the second positioning pin is inserted into the third and fourth positioning holes, and the second sleeve 15 is fixed to the end limiting rod 8, thus completing the angle adjustment of the flow guide panel 16.
[0039] See Figure 4 Based on the above structure, the present invention also discloses a heat exchanger ventilation and flow equalization method, comprising the following steps: S1, the ventilation and airflow equalization device is placed on one side of the air inlet 2 of the heat exchanger, so that the device directly acts on the airflow entering the heat exchanger, which facilitates targeted guidance and adjustment of the airflow.
[0040] S2, the position of the guide panel 16 on the support frame 11 is adjusted by the axial sliding part 12, and the axial sliding part 12 is fixed on the support frame 11 by the first locking part; since heat exchangers of different specifications have differences in height and other dimensions, the position of the guide panel 16 on the support frame can be adjusted by the axial sliding part 12 to make the ventilation flow equalization device adapt to heat exchangers of various heights.
[0041] S3, the angle of the guide panel 16 is adjusted by the angle adjustment unit 13, thereby changing the airflow direction. This allows the airflow to enter the heat exchanger in the most suitable direction, ensuring that the airflow can fully exchange heat with the medium inside the heat exchanger and improving heat exchange efficiency. In actual operation, the operating conditions of the heat exchanger may change, such as changes in parameters like ambient temperature, medium flow rate, and heat exchange capacity. By adjusting the angle of the guide panel 16 in a timely manner by the angle adjustment unit, these changes in operating conditions can be flexibly addressed, ensuring that the ventilation and flow equalization device can always provide the best airflow guidance effect, guaranteeing that the heat exchanger maintains high cooling efficiency under different operating conditions, and improving the adaptability and stability of the entire system.
[0042] See Figure 2 This invention allows for the installation of one or more heat exchanger ventilation and flow equalization devices along the length or width of heat exchanger 1, depending on the arrangement of heat exchanger 1, to guide cold air evenly through the heat exchanger. The planar spacing of the guide panels 16 is adjustable to meet the requirements for isolated air intake between different groups of heat exchangers. When the heat exchange requirements of each group of heat exchangers are different and the air intake volume needs to be adapted, the air intake volume can be flexibly adjusted by adjusting the angle between the plane of the heat exchanger ventilation and flow equalization device and the heat exchanger to adapt to different heat exchange requirements, thereby improving the applicability and flexibility of the device under different operating conditions.
[0043] Example 2: See Figure 1 This invention discloses a heat exchanger ventilation and flow equalization device. Unlike the above embodiments, the cross-sectional shape of the movable plate 4 in this embodiment is arc-shaped. When the planar distance between the first guide panel 9 and the second guide panel 10 in the same group is adjusted to the minimum, the movable plates 4 of the first guide panel 9 and the second guide panel 10 interlock, so that the first guide panel 9 and the second guide panel 10 close alternately, thereby isolating the air inlet channels between each group.
[0044] Unlike the above embodiments, the angle adjustment part 13 in this embodiment includes a movable plate connecting rod 3, an end limiting rod 8, and a second locking part. The movable plate connecting rod 3 is a telescopic rod. The flow guide panel 16 is connected to the end limiting rod 8 through the movable plate connecting rod 3. The movable plate connecting rod 3 is movably connected to a second sleeve 15. The second sleeve 15 is slidably sleeved on the end limiting rod 8. The second sleeve 15 is detachably and fixedly connected to the end limiting rod 8 through the second locking part.
[0045] During the angle adjustment of the flow guide panel 16, the second locking part is opened, allowing the second sleeve 15 to slide freely on the end limiting rod 8. The telescopic rod extends and retracts simultaneously. After all the flow guide panels 16 are adjusted to their correct angles, the second locking part secures the second sleeve 15 to the end limiting rod 8, completing the angle adjustment of the flow guide panel 16. The telescopic rod ensures that the end limiting rod 8 remains fixed at all times.
[0046] In this embodiment of the invention, the end limiting rod 8 is connected and fixed to the support frame 11, thereby increasing the overall stability of the device.
[0047] Example 3: See Figure 1 , Figure 2 The present invention provides a heat exchanger ventilation and flow equalization device, the shape of which can be determined according to the shape of multiple heat exchangers 1 enclosed, and the projection of the ventilation and flow equalization device in the first direction AB is a triangle, a polygon or a fan shape.
[0048] In this embodiment, two heat exchangers 1 are arranged vertically at a certain angle. The projection of the heat exchanger ventilation and flow equalization device in the first direction AB is a triangle. The heat exchanger ventilation and flow equalization device is set on one side of the air inlet 2 of the heat exchanger. The heat exchanger ventilation and flow equalization device can be perpendicular to the surface of the heat exchanger 1 or at a certain angle. One or more heat exchanger ventilation and flow equalization devices can be set along the height direction of the heat exchanger 1.
[0049] The heat exchanger ventilation and flow equalization device consists of a first guide panel 9 and a second guide panel 10. Both the first and second guide panels 9 and 10 are provided with several rows of movable plates 4. The movable plates 4 of the first and second guide panels 9 and 10 can be arranged parallel to each other along a plane with the same or different gaps. The width of the movable plates 4 of the second guide panel 10 is slightly larger than the gap between the movable plates 4 of the first guide panel 9, and the gap between the movable plates 4 of the second guide panel 10 is slightly smaller than the width of the movable plates 4 of the first guide panel 9. The distance between the first and second guide panels 9 and 10 can be adjusted along the distance adjustment axis 6. When the first and second guide panels 9 and 10 are parallel and the distance is minimal, see [reference needed]. Figure 3The movable plates 4 of the first guide panel 9 and the second guide panel 10 are completely closed, completely isolating the space on both sides. The distance between the first guide panel 9 and the second guide panel 10 can be gradually increased along the distance adjustment axis 6. The opening height between the first guide panel 9 and the second guide panel 10 can be adjusted to allow limited flow in the space on both sides of the heat exchanger ventilation equalization device and balance the pressure difference. The angle of the first guide panel 9 and the second guide panel 10 is adjustable to guide the direction of airflow. The included angle between the first guide panel 9 and the second guide panel 10 can be the same, i.e., parallel, or different. When the heat exchange demand of each group of heat exchangers is different and the air intake volume needs to be adapted, the first guide panel 9 and the second guide panel 10 are rotated along the plane angle adjustment axis 7 to adjust the angle between the ventilation direction of the heat exchanger ventilation equalization device and the heat exchanger. For heat exchangers with large heat exchange capacity, the air inlet area is increased, and for heat exchangers with small heat exchange capacity, the air inlet area is decreased. When adjusting the plane angle, the end limit rod 8 can move forward and up and down. The vertical distance between the end of the movable plate connecting rod and the line connecting the distance adjustment shaft 6 is adjusted according to the required angle. By reasonably setting the airflow equalization device on the air inlet side of the heat exchanger, the overall heat exchanger achieves the best heat dissipation effect.
[0050] The above content is only for illustrating the technical concept of the present invention and should not be construed as limiting the scope of protection of the present invention. Any modifications made to the technical solution based on the technical concept proposed in this invention shall fall within the scope of protection of this invention.
