Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and specifically to a high-stability heat exchange mechanism for cooling towers. Background Technology

[0002] Closed-circuit cooling towers are increasingly widely used due to their high heat exchange performance and small footprint. In application, the condenser assembly is the core component of a closed-circuit cooling tower. Existing condenser assemblies consist of several evenly distributed condenser tubes, which are composed of straight and bent tubes connected end-to-end and fixedly installed on the outer frame. Because the temperature of the heat exchange medium in contact with the condenser tubes at different locations varies, the deformation of the condenser tubes at different locations also varies. Therefore, cracks are prone to appear at the connection points between the bent and straight tubes, causing leakage of the heat exchange medium. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a high-stability heat exchange mechanism for cooling towers, wherein one of the connecting components at both ends of the heat exchange structure is fixedly installed on the frame and the other is movably installed on the frame. During the heating process, the movably installed connecting component moves relative to the frame, which can effectively avoid the sealing effect between the heat exchange tube and the flat plate being affected by thermal expansion and contraction.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A high-stability heat exchange mechanism for a cooling tower includes a frame on which a plurality of heat exchange structures are mounted in a vertical direction. Each heat exchange structure has a connecting component at both ends passing through the frame. A connection port is provided in the middle of the connecting component. Connecting pipes are provided between adjacent connection ports at the same end of the plurality of heat exchange structures. The connecting pipes at both ends of the heat exchange structures are distributed alternately. One connecting component at the same end of the plurality of heat exchange structures is fixedly mounted on the frame. Another connecting component at the same end of the plurality of heat exchange structures is movably connected to the frame by a connecting structure.

[0006] Preferably, the heat exchange structure includes a plurality of uniformly distributed heat exchange tubes, and spiral fins are installed on the outer side of the heat exchange tubes.

[0007] Preferably, the connecting component is a closed semi-circular cylinder, the semi-circular cylinder includes a flat plate and an arc-shaped panel, the connection port is located at the center of the arc surface of the arc-shaped panel, and a plurality of the heat exchange tubes are evenly installed on the flat plate.

[0008] Preferably, the connection structure includes a plurality of evenly distributed mounting holes corresponding to the flat plate and the frame, bolts are installed in the mounting holes, one end of the bolts passes through the frame and the flat plate in sequence and is threaded with a nut, and a pressure spring is fitted on the bolt between the nut and the flat plate.

[0009] Preferably, a plurality of evenly distributed guide posts are fixedly installed on the frame, and the flat plate is provided with support holes that cooperate with the guide posts. The guide posts are inserted into the support holes and abut against the inner wall of the support holes.

[0010] The beneficial effects of this utility model are as follows:

[0011] In this utility model, one of the connecting components at both ends of the heat exchange structure is fixedly installed on the frame and the other is movably installed on the frame. During the process of the heat exchange tube being heated, the movably installed connecting component moves relative to the frame, which can effectively avoid the sealing effect between the heat exchange tube and the flat plate being affected by thermal expansion and contraction.

[0012] In this invention, a semi-circular cylinder is used to redirect and redistribute the heat exchange material in different heat exchange tubes. The convergence of the heat exchange material in the semi-circular cylinder can be used to adjust the temperature of the heat exchange material, making the temperature of the heat exchange material in the semi-circular cylinder more uniform. With multiple uses of the semi-circular cylinder, the temperature of the heat exchange material can be adjusted multiple times, which can effectively improve the overall heat exchange effect.

[0013] In this utility model, the guide post and the support hole are used to support the movable connecting component, which can effectively avoid the problem of heat exchange tube deformation or even breakage at the connection between the heat exchange tube and the flat plate due to its own weight.

[0014] This invention utilizes a bolt and a pressure spring in combination. The pressure spring can absorb the stress generated by the thermal expansion and contraction of the heat exchange tube, thus ensuring the stability of the connection between the flat plate and the heat exchange tube.

[0018] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0019] like Figure 1-2 The high-stability heat exchange mechanism for a cooling tower shown includes a frame 1. Several heat exchange structures 4 distributed vertically are mounted on the frame 1. Each heat exchange structure 4 has a connecting component 2 passing through both ends of the frame 1. A connection port is provided in the middle of each connecting component 2. Connecting pipes 3 connect adjacent connection ports at the same end of the heat exchange structures 4. The connecting pipes 3 at both ends of the heat exchange structures 4 are alternately distributed. One connecting component 2 at the same end of the heat exchange structures 4 is fixedly mounted on the frame 1. Another connecting component 2 at the same end of the heat exchange structures 4 is movably connected to the frame 1 via a connecting structure 5. One connecting component 2 at each end of the heat exchange structure 4 is fixedly mounted on the frame 1, and the other is movably mounted on the frame 1. During the heating process, the movably mounted connecting component 2 allows relative movement between the heat exchange tube and the frame 1, effectively preventing thermal expansion and contraction from affecting the sealing effect between the heat exchange tube and the flat plate.

[0020] The heat exchange structure 4 includes several uniformly distributed heat exchange tubes. Spiral fins are installed on the outside of the heat exchange tubes. The spiral fins can increase the contact area between the spray water and the heat exchange structure 4 and delay the fall of the spray water, which can effectively improve the heat exchange efficiency.

[0021] The connecting component 2 is configured as a closed semi-circular cylinder, which includes a flat plate and an arc-shaped panel. The connection port is located at the center of the arc-shaped surface of the arc-shaped panel. Several heat exchange tubes are evenly installed on the flat plate. The semi-circular cylinder is used to redirect and redistribute the heat exchange material in different heat exchange tubes. The convergence of the heat exchange material in the semi-circular cylinder can be used to adjust the temperature of the heat exchange material, making the temperature of the heat exchange material in the semi-circular cylinder more uniform. With multiple uses of the semi-circular cylinder, the temperature of the heat exchange material can be adjusted multiple times, which can effectively improve the overall heat exchange effect.

[0022] The connection structure 5 includes a plurality of evenly distributed mounting holes corresponding to the planar plate and the frame 1. Bolts 501 are installed in the mounting holes. One end of the bolt 501 passes through the frame 1 and the planar plate and is threaded with a nut 502. A pressure spring 503 is fitted on the bolt 501 between the nut 502 and the planar plate. The bolt 501 and the pressure spring 503 cooperate to absorb the stress generated by the thermal expansion and contraction of the heat exchange tube, which can ensure the stability of the connection between the planar plate and the heat exchange tube.

[0023] A plurality of evenly distributed guide posts 504 are fixedly installed on the frame 1. The flat plate is provided with support holes 505 that cooperate with the guide posts 504. The guide posts 504 are inserted into the support holes 505 and abut against the inner wall of the support holes 505. By using the cooperation between the guide posts 504 and the support holes 505, the movable connecting component 2 can be supported, which can effectively avoid the problem of heat exchange tube deformation or even breakage at the connection between the heat exchange tube and the flat plate due to its own weight.

[0024] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
