Description

Technical Field

[0001] This utility model relates to the field of heat exchange equipment technology, and in particular to an air cooler. Background Technology

[0002] The temperature of the gas-liquid mixture delivered to the distribution station is generally between 25℃ and 50℃, such as oil, gas, water, and methanol. It needs to be cooled to 15℃-20℃ by an air cooler before being sent to a gas-liquid separator for separation. The air cooler is made up of multiple air cooler pipes spliced ​​together. During the operation of the air cooler, if one of the air cooler pipes leaks, the damaged air cooler pipe needs to be repaired or replaced to ensure the operation of the air cooler.

[0003] Chinese patent CN217383875U discloses an air cooler for a gas storage facility, including a frame, tube bundle components, and a fan. The frame includes four side plates, eight corner braces, an annular protective plate, and four matrix-distributed columns. The side plates are connected to adjacent columns by multiple bolts, and two diagonally opposite columns are connected by support plates. The annular protective plate and the fan are mounted on the support plates, with the fan located inside the annular protective plate. The bottom of each side plate is connected to the corresponding column by two corner braces. The tube bundle components... It includes a tube box, multiple sets of corrugated pressure strips, and multiple heat exchange tubes. The tube box is open at the bottom and top. Multiple heat exchange tubes are arrayed inside the tube box. Two rows of heat exchange tubes are separated by a set of corrugated pressure strips. The tube bundle components are assembled on the top of the frame. In use, for one row of heat exchange tubes, adjacent heat exchange tubes are connected by connecting pipes. When the medium to be cooled is input into the air cooler, it will circulate through all the heat exchange tubes before flowing out. The medium to be cooled circulates in the heat exchange tubes, and the heat is dissipated by the fan, thereby achieving the cooling effect.

[0004] However, each set of corrugated strips is welded inside the tube box, and two adjacent rows of heat exchange tube bundles are separated by a set of corrugated strips. Furthermore, a set of corrugated strips is also welded to the top of the heat exchange tube. If one of the heat exchange tube bundles is damaged and leaks and needs to be replaced, the staff must first remove the corrugated strips layer by layer before replacing the heat exchange tube bundle, which takes a lot of time and is inconvenient to disassemble.

[0032] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0033] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] It should be understood that the terms "first," "second," etc., are used in this utility model to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be called "second" information, and similarly, "second" information can also be called "first" information.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] like Figures 1 to 6As shown, a preferred embodiment of the present invention provides an air cooler comprising: a housing 1, wherein air cooling pipes, a first clamping frame 141, a second clamping frame 142, and a driving device are disposed within the housing 1; the length direction of the air cooler is defined as the first direction X, and the width direction of the air cooler is defined as the second direction Y, wherein the first direction X and the second direction Y are perpendicular to each other; the air cooling pipes include a plurality of U-shaped pipes 12, each U-shaped pipe 12 extending along the first direction X of the housing 1, and adjacent U-shaped pipes 12 being connected by connecting pipes to form a continuous flow channel, allowing the heat exchange medium to circulate within the heat dissipation assembly.

[0037] The first clamping frame 141 and / or the second clamping frame 142 slide along the second direction Y; the driving device is fixed inside the housing 1 and is connected to the first clamping frame 141 and / or the second clamping frame 142 to drive the first clamping frame 141 and the second clamping frame 142 to slide closer or further away. The first clamping frame 141 and the second clamping frame 142 slide closer to form a clamping space for clamping air-cooled pipe fittings. By setting the first clamping frame 141 and the second clamping frame 142 to slide along the second direction Y, and cooperating with the driving device, the clamping space can be quickly adjusted, which solves the problem of cumbersome replacement of heat exchange tube bundles caused by welded corrugated pressure strips in traditional air coolers, significantly improving maintenance efficiency and reducing disassembly and assembly time. At the same time, the transmission connection between the driving device and the clamping frame simplifies the operation process and reduces the intensity of manual labor. In addition, the adjustability of the clamping space adapts to the needs of air-cooled pipe fittings of different sizes, improves the structural versatility, and reflects the advantages of modular design.

[0038] Specifically, both ends of the first clamping frame 141 along the first direction X are connected to the driving device, and both ends of the second clamping frame 142 along the first direction X are also connected to the driving device. The bottom wall of the housing 1 is symmetrically provided with sliding grooves 23 extending along the second direction Y of the housing 1. The bottom of the first clamping frame 141 and the second clamping frame 142 are provided with sliders (not shown in the figure). The sliders are slidably disposed in the sliding grooves 23, thereby realizing the sliding of the first clamping frame 141 and the second clamping frame 142 relative to the housing 1. This achieves precise guiding sliding of the clamping frames along the second direction Y of the housing 1. The driving device synchronously drives the first clamping frame 141 and the second clamping frame 142 to slide closer or further away, improving the stability and synchronicity of the clamping action.

[0039] Specifically, a drive device is provided at both ends of the housing 1 along the first direction X. Each drive device includes a drive component, a transmission plate 18 and a first gear 161. The drive component is fixed on the bottom wall of the housing 1. The first gear 161 is rotatably mounted on the bottom wall of the housing 1. A positioning rod 17 is provided on the bottom wall of the housing 1. A bearing 6 is on the positioning rod 17. The inner ring of the bearing 6 is fixedly connected to the outer wall of the positioning rod 17. The outer ring of the bearing 6 is fixedly connected to the first gear 161, thereby realizing that the first gear 161 is rotatably mounted on the bottom wall of the housing 1.

[0040] The first clamping frame 141 has a first rack 151 at both ends along the first direction X, and a first gear 161 meshes with the first rack 151. One end of the transmission plate 18 is hinged to the driving end of the driving member, and the other end of the transmission plate 18 is hinged to the first gear 161. The hinge point between the transmission plate 18 and the first gear 161 is located at the edge of the first gear 161. The power output by the driving member is transmitted to the transmission plate 18. The transmission plate 18 converts the motion into the rotational motion of the first gear 161 through the hinge at both ends, thereby driving the first clamping frame 141 to slide, improving the clamping stability. The meshing characteristics of the gear and rack, combined with the dead point position of the linkage mechanism, can form a self-locking mechanism in the clamping state, preventing the clamping frame from loosening due to vibration or external force, thus improving safety. Furthermore, the hinge point between the transmission plate 18 and the first gear 161 is located at the edge of the first gear 161, which shortens the transmission path of the transmission plate 18 to the first gear 161 and reduces the stress concentration between the transmission plate 18 and the first gear 161.

[0041] Specifically, each drive device also includes a second gear 162, which is rotatably mounted on the bottom wall of the housing 1. A positioning rod 17 is provided on the bottom wall of the housing 1, and a bearing 6 is on the positioning rod 17. The inner ring of the bearing 6 is fixedly connected to the outer wall of the positioning rod 17, and the outer ring of the bearing 6 is fixedly connected to the first gear 161, thereby realizing that the first gear 161 is rotatably mounted on the bottom wall of the housing 1.

[0042] The second clamping frame 142 has second racks 152 at both ends along the first direction X, and the second gear 162 meshes with the second racks 152; the driving member has transmission plates 18 on both sides along the second direction Y, one end of one transmission plate 18 is hinged to the driving end of the driving member, and the other end of the transmission plate 18 is hinged to the first gear 161, with the hinge point between the transmission plate 18 and the first gear 161 located at the edge of the first gear 161; the other transmission plate 18 has one end hinged to the driving end of the driving member, and the transmission... The other end of the transmission plate 18 is hinged to the second gear 162, and the hinge point between the transmission plate 18 and the second gear 162 is located at the edge of the second gear 162; the driving member is provided with transmission plates 18 on both sides along the second direction Y, so that when the driving member moves, the transmission plates 18 on both sides synchronously convert the movement of the driving member into the rotation of the first gear 161 and the second gear 162, thereby driving the first clamping frame 141 and the second clamping frame 142 to slide synchronously, avoiding the clamping frame from generating off-center load due to asynchronous movement, and improving clamping stability.

[0043] Specifically, each driving component has an active push plate 19 at its driving end, and one end of each transmission plate 18 is hinged to the active push plate 19. This avoids reducing the structural strength of the driving component by opening multiple mounting holes at its driving end, resulting in a compact structure and reasonable layout.

[0044] Specifically, the first gear 161 has a first notch at one end facing the inner cavity of the housing 1, and the second gear 162 has a second notch at one end facing the inner cavity of the housing 1. The notch design avoids interference between the driving end of the drive component and the first gear 161 or the second gear 162, ensuring the stability of the drive component's driving process. At the same time, the notch forms a stroke limit. Taking the first gear 161 as an example, when the first gear 161 rotates to the position of the first notch, the first gear 161 disengages from the first rack 151, stopping further driving the first clamping frame 141 to slide, preventing the first clamping frame 141 from sliding too much and causing structural damage.

[0045] Specifically, the bottom of the housing 1 is provided with a first auxiliary meshing block 71, which is located at the end of the first gear 161 away from the first notch. The first auxiliary meshing block 71 is used to stop the first gear 161 when it deviates laterally. The bottom of the housing 1 is provided with a second auxiliary meshing block 72, which is located at the end of the second gear 162 away from the second notch. The second auxiliary meshing block 72 is used to stop the second gear 162 when it deviates laterally. The first auxiliary meshing block 71 and the second auxiliary meshing block 72 further restrict the axial movement of the gears during transmission, so as to avoid tooth loss or transmission failure caused by axial deviation.

[0046] Specifically, each driving component is a cylinder 21, the driving end of the cylinder 21 is a driving guide plate 20, and the bottom wall of the housing 1 is provided with a mounting groove 8. The cylinder 21 is fixed in the mounting groove 8, which saves space and facilitates maintenance.

[0047] Specifically, the air-cooled tubes are provided with clamping rings 13 at both ends along the first direction X for clamping the air-cooled tubes. The clamping rings 13 assist in clamping the U-shaped tubes 12 and can still provide redundant clamping force when the first clamping frame 141 and the second clamping frame 142 are released, effectively preventing the heat exchange tube bundle from displacing due to vibration or thermal stress. When it is necessary to replace the U-shaped tubes 12, the U-shaped tubes 12 can be quickly disassembled and replaced simply by removing the clamping rings 13, which improves the ease of operation.

[0048] Specifically, the bottom of the housing 1 is equipped with at least one mounting bracket 4, and each mounting bracket 4 is fitted with a cooling fan 5. The top of the housing 1 is equipped with a top cover, which has several louvers 22. The mounting brackets 4 at the bottom of the housing 1 are used to fix the cooling fans 5, ensuring the stability of fan operation and facilitating maintenance. The louvers 22 on the top cover can adjust the airflow direction and flow rate, enhancing cooling efficiency while preventing external debris from entering. The airflow is evenly distributed by controlling the opening of the louvers 22. Combined with forced cooling at the bottom and controllable airflow discharge at the top, the overall heat dissipation performance of the air cooler is effectively improved.

[0049] Specifically, the bottom of the housing 1 is equipped with two mounting brackets 4.

[0050] Specifically, both ends of the housing 1 in the first direction X are provided with tube boxes 9. The side wall of the tube box 9 is provided with several evenly distributed through holes 10. Each through hole 10 is fixedly connected with a plug 11. The plug 11 seals each through hole 10 by a compression gasket to ensure that the tube box 9 does not leak under the medium pressure. At the same time, when it is necessary to clean the blocked heat exchange tubes or repair the leaking parts, the plug 11 can be removed to facilitate equipment maintenance.

[0051] One of the pipe boxes 9 has an inlet and an outlet at the top, with the inlet connected to the inlet of the heat dissipation component and the outlet of the heat dissipation component connected to the outlet.

[0052] Support legs 2 are fixedly connected to the four corners of the bottom of the box 1.

[0053] In other embodiments, the width direction of the box 1 can also be defined as the first direction X, and the length direction of the box 1 can be defined as the second direction Y.

[0054] In other embodiments, the drive device can be driven to only one end of the first clamping frame 141 along the first direction X. In this case, the drive device can drive the first clamping frame 141 to slide by moving one end of the first clamping frame 141 along the first direction X. This can also make the first clamping frame 141 and the second clamping frame 142 slide closer or slide further apart.

[0055] In other embodiments, the drive device can be driven to only one end of the second clamping frame 142 along the first direction X. In this case, the drive device can drive the second clamping frame 142 to slide by moving one end of the second clamping frame 142 along the first direction X. This can also make the first clamping frame 141 and the second clamping frame 142 slide closer or slide further apart.

[0056] In other embodiments, the drive device can be driven only to the two ends of the first clamping frame 141 along the first direction X. In this case, the drive device can drive the first clamping frame 141 to slide by driving the two ends of the first clamping frame 141 to move synchronously in the first direction X. This can also make the first clamping frame 141 and the second clamping frame 142 slide closer or slide further apart.

[0057] In other embodiments, the drive device can be driven only to the two ends of the second clamping frame 142 along the first direction X. In this case, the drive device can drive the second clamping frame 142 to slide by moving the two ends of the second clamping frame 142 along the first direction X. This can also make the first clamping frame 141 and the second clamping frame 142 slide closer or slide further apart.

[0058] The working process of this utility model is as follows: The air-cooled pipe fitting is initially clamped at both ends using clamping rings 13. Then, the initially clamped U-shaped pipe 12 is placed in the middle of the first clamping frame 141 and the second clamping frame 142. After the cylinder 21 is opened, the drive guide plate 20 of the cylinder 21 moves linearly, driving the active push plate 19 to move linearly. The transmission plate 18 transmits power to the first gear 161 and the second gear 162, synchronously driving the first gear 161 and the second gear 162 to rotate. During the process, the first rack 151 and the second rack 152 drive the first clamping frame 141 and the second clamping frame 142 to move towards each other or away from each other, thereby clamping or releasing multiple U-shaped tubes 12. After the entire air cooler starts to operate, the cooling fans inside the two mounting brackets 4 start at the same time, causing the air to circulate in the box 1. The relatively low temperature air from the outside is introduced, and after passing through the louvers 22, it flows through the surface of each U-shaped tube 12 and exchanges heat with the high temperature U-shaped tube 12, taking away the heat emitted by the U-shaped tube 12.

[0059] In summary, this utility model embodiment provides an air cooler that, by setting a first clamping frame and a second clamping frame that slide along a second direction, and in conjunction with a driving device, enables rapid adjustment of the clamping space. This solves the problem of cumbersome heat exchange tube bundle replacement caused by welded corrugated pressure strips in traditional air coolers, significantly improving maintenance efficiency and reducing disassembly and assembly time. At the same time, the transmission connection between the driving device and the clamping frame simplifies the operation process and reduces manual labor intensity. Furthermore, the adjustability of the clamping space adapts to the needs of air cooler fittings of different sizes, improving structural versatility and demonstrating the advantages of modular design.

[0060] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
