Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically to a water distribution structure for heat exchange components. Background Technology

[0002] In existing technologies, gas-liquid heat exchange components and gas-to-gas heat exchange components are commonly used in cooling towers, especially condensing defogging and water-saving cooling towers. The gas-liquid heat exchange component (usually a water-spraying packing component) is used for gas-liquid contact heat exchange between dry, cold air and circulating water to cool the circulating water, and humid, hot air is generated after the heat exchange. The gas-to-gas heat exchange component is placed above the water-spraying packing to eliminate white mist. The gas-to-gas heat exchange component has different channels, which allow the humid, hot air generated after the gas-liquid heat exchange in the water-spraying packing component inside the tower to undergo indirect heat exchange with the dry, cold air outside the tower.

[0003] The prior art discloses a patent with publication number CN118361993B, which includes alternating first and second plates to form cold and hot channels. Both the first and second plates include an integrally formed main heat exchange zone and an efficiency-enhancing heat exchange zone. The main heat exchange zone, from top to bottom, has an upper guide zone, a heat exchange zone, and a lower guide zone. Both the cold and hot channels have one outlet and two inlets. The cold channel inlet is located in the middle half-width section at the bottom of the heat exchange component, and the two outlets are located on the two sides of the top quarter-width section. The hot channel inlet is located in the middle half-width section at the top of the component, and the two outlets are located on the two sides of the bottom quarter-width section of the component block. This invention, while achieving defogging and circulating water cooling, can completely eliminate fogging in low-temperature environments such as winter, and reduces resistance within the tower and component flow channels. It can reduce ineffective heat exchange areas and increase the overall heat exchange area.

[0004] The shortcomings of existing technology have gradually become apparent with use, mainly in the following aspects:

[0005] The existing water distribution structure has a narrow adjustment range, making it impossible to switch between summer, winter, and spring / autumn modes, and unable to make fine adjustments according to different climates.

[0006] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a water distribution structure for heat exchange components, which solves the problems of narrow adjustment range, inability to switch between summer, winter and spring / autumn modes, and inability to make fine adjustments according to different climates in the existing water distribution structures of traditional technologies.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A water distribution structure for a heat exchange component includes a tower body. The tower body is provided with an anti-fogging water distribution main pipe and a regular water distribution main pipe. The anti-fogging water distribution main pipe and the regular water distribution main pipe are each provided with several branch pipe groups in parallel. The branch pipe groups of the anti-fogging water distribution main pipe and the regular water distribution main pipe are arranged alternately. The branch pipe group includes a regular branch pipe, a summer branch pipe, and a regulating branch pipe arranged in parallel.

[0010] As an optimized solution, the summer branch pipe is located within the cold aisle of the tower body.

[0011] As an optimized solution, the normal branch pipe and the regulating branch pipe are located in the hot channel of the tower body.

[0012] As an optimized solution, the normal branch pipe and the regulating branch pipe are located directly above the partition used to separate the hot passage and the cold passage, and the normal branch pipe and the regulating branch pipe are respectively connected to the nozzle located in the middle of the hot passage through parallel right-angle connecting pipes.

[0013] As an optimized solution, the nozzles on the normal branch pipe, summer branch pipe, and regulating branch pipe are at the same horizontal height.

[0014] As an optimized solution, the adjusting branch pipe is higher than the nozzle height of the summer branch pipe, and the nozzle height of the summer branch pipe is the same as that of the normal branch pipe.

[0015] As an optimized solution, the height of the normal branch pipe and the regulating branch pipe is the same, and the summer branch pipe is lower than the normal branch pipe and the regulating branch pipe.

[0016] As an optimized solution, the summer branch pipe is at the same horizontal level as the normal branch pipe and the regulating branch pipe.

[0017] As an optimized solution, the conventional water distribution main pipe is located on one side of the air inlet surface of the tower body, and the anti-fog water distribution main pipe is located outside the tower body. The conventional water distribution main pipe and the anti-fog water distribution main pipe are arranged perpendicularly to each other in the top view direction.

[0018] As an optimized solution, the anti-fog water distribution main pipe and the conventional water distribution main pipe are arranged side by side, with the anti-fog water distribution main pipe located above the conventional water distribution main pipe.

[0019] As an optimized solution, several branch pipe groups located on the main defogging water distribution pipe and the conventional main water distribution pipe are at the same height.

[0020] As an optimized solution, the anti-fog water distribution main pipe and the conventional water distribution main pipe are located on opposite sides of the tower body.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] (1) The height of the normal branch pipe and the regulating branch pipe is the same. In summer, the branch pipe is lower than the normal branch pipe and the regulating branch pipe. This arrangement can effectively reduce the wind resistance caused by the branch pipes being at the same height.

[0023] (2) When the normal branch pipe, summer branch pipe, and regulating branch pipe are at the same height, in order to reduce wind resistance, a branch pipe with a smaller diameter can be selected.

[0024] The system is divided into regular branch management, summer branch management, and adjustment branch management. The switching between summer mode, winter mode, and spring / autumn mode is achieved by switching between the branch managements.

[0025] Summer mode: Summer mode is the normal cooling state. The heat exchange components are used as ordinary packing. Water flows through the summer branch pipe of the cold aisle and the normal branch pipe of the hot aisle. The regulating branch pipe is closed.

[0026] Winter mode: Winter mode is the defogging mode. The heat exchange component's heat channel normally has both the main branch pipe and the regulating branch pipe open (the nozzles of the two branch pipes in the heat channel can be at the same height or at different heights; the height configuration helps reduce ventilation resistance). The branch pipes are closed in summer.

[0027] Spring and Autumn Mode: Spring and Autumn Mode can adjust some heat exchange components that are in winter mode to summer mode based on the cooling tower's fogging situation, while keeping some heat exchange components in winter mode, in order to meet the fogging requirements.

[0028] (3) The two conventional water distribution main pipes and the anti-fog water distribution main pipe are arranged in a top view direction, with the anti-fog water distribution main pipe located on one side of the air inlet side of the tower body and the conventional water distribution main pipe located inside the tower body.

[0029] In winter mode, the main water distribution pipe for defogging is running, the hot channel of the heat exchange component is filled with water, the main water distribution pipe for regular use is stopped, and the cold channel of the heat exchange component is not filled with water.

[0030] In summer mode, both the defogging water main and the regular water main are in operation, and water flows through both the hot and cold channels of the heat exchange components.

[0031] (4) The anti-fog water distribution main is located above the conventional water distribution main. The two sets of water distribution mains are arranged vertically, and the branch pipes are at the same height. The anti-fog water distribution main is on top, and the conventional water distribution main is on the bottom.

[0032] In winter mode, the defogging water distribution main pipe is running, the hot channel of the heat exchange component is filled with water, the regular water distribution main pipe is stopped, and the cold channel of the heat exchange component is not filled with water.

[0033] In summer mode, both the defogging water main and the regular water main are in operation, and water flows through both the hot and cold channels of the heat exchange components.

[0034] (5) The main water distribution pipe for fog elimination and the main water distribution pipe for conventional water distribution are located on both sides of the tower body, and both are arranged in a branch-shaped water distribution pattern;

[0035] In winter mode, the defogging water distribution main pipe is running, the hot channel of the heat exchange component is filled with water, the regular water distribution main pipe is stopped, and the cold channel of the heat exchange component is not filled with water.

[0036] In summer mode, both the defogging water main and the regular water main are in operation, and water flows through both the hot and cold channels of the heat exchange components. Attached Figure Description

[0044] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0045] Example 1,

[0046] like Figure 1 As shown, the tower body includes a main water distribution pipe 4 and a conventional water distribution pipe 5. The main water distribution pipe 4 and the conventional water distribution pipe 5 are each provided with several branch pipe groups in parallel. The branch pipe groups of the main water distribution pipe 4 and the conventional water distribution pipe 5 are arranged alternately. The branch pipe group includes a conventional branch pipe 1, a summer branch pipe 2, and a regulating branch pipe 3 arranged in parallel.

[0047] A main water supply pipe is installed outside the tower, and the fog-dissipating water supply pipe 4 and the regular water supply pipe 5 are branches of the main water supply pipe.

[0048] In summer, branch pipe 2 is located in the cold aisle of the tower.

[0049] Normal branch pipe 1 and regulating branch pipe 3 are located in the hot channel of the tower body.

[0050] Normal branch pipe 1 and regulating branch pipe 3 are located directly above the partition used to separate the hot passage and the cold passage, respectively. Normal branch pipe 1 and regulating branch pipe 3 are respectively connected to nozzles located in the middle of the hot passage through parallel right-angle connecting pipes.

[0051] Normal branch pipe 1, summer branch pipe 2, and regulating branch pipe 3 are at the same height.

[0052] The height of the normal branch pipe 1 and the regulating branch pipe 3 is the same. The summer branch pipe 2 is lower than the normal branch pipe 1 and the regulating branch pipe 3. The normal branch pipe 1, the summer branch pipe 2 and the regulating branch pipe 3 are separated from the main pipe. The switching between the summer mode, the winter mode and the spring and autumn mode is realized by switching between the branches.

[0053] Summer mode: Summer mode is the normal cooling state. The heat exchange components are used as ordinary packing. Water flows through the summer branch pipe 2 of the cold aisle and the normal branch pipe 1 of the hot aisle. The regulating branch pipe 3 is closed.

[0054] Winter mode: Winter mode is the defogging state. The heat exchange component's heat channel normally opens branch pipe 1 and regulating branch pipe 3 (the nozzles of the two branch pipes in the heat channel can be at the same height or at different heights; the height configuration helps reduce ventilation resistance). Summer branch pipe 2 is closed.

[0055] Spring and Autumn Mode: Spring and Autumn Mode can adjust some heat exchange components that are in winter mode to summer mode based on the cooling tower's fogging situation, while keeping some heat exchange components in winter mode, in order to meet the fogging requirements.

[0056] When the normal branch pipe 1, summer branch pipe 2, and regulating branch pipe 3 are at the same height, in order to reduce wind resistance, a branch pipe with a smaller diameter can be selected.

[0057] Example 2,

[0058] like Figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the height of the normal branch pipe 1 and the regulating branch pipe 3 are the same. This arrangement can effectively reduce the wind resistance caused by the branch pipes being at the same height.

[0059] Example 3,

[0060] like Figure 3As shown, the difference between this embodiment and Embodiment 1 is that the conventional water distribution main pipe is located on one side of the air inlet surface of the tower body, while the anti-fog water distribution main pipe is located outside the tower body, and the conventional water distribution main pipe and the anti-fog water distribution main pipe are arranged vertically along the top view direction.

[0061] In winter mode, the defogging water distribution main pipe 4 is running, and the hot channel of the heat exchange component is filled with water. The regular water distribution main pipe 5 is stopped, and the cold channel of the heat exchange component is not filled with water.

[0062] In summer mode, both the defogging water distribution main pipe 4 and the regular water distribution main pipe 5 are in operation, and water is flowing through both the hot and cold channels of the heat exchange components.

[0063] Example 4,

[0064] like Figure 4 As shown, the difference between this embodiment and embodiment one is that the anti-fog water distribution main pipe 4 and the conventional water distribution main pipe 5 are arranged side by side, with the anti-fog water distribution main pipe 4 located above the conventional water distribution main pipe 5. The anti-fog water distribution main pipe 4 and the conventional water distribution main pipe 5 are arranged in a manner with equal or varying diameters to ensure that the flow rate entering each branch pipe is consistent.

[0065] Several branch pipe groups located on the main water distribution pipe for fog suppression and the main water distribution pipe 5 are at the same height.

[0066] Two sets of main water distribution pipes are arranged vertically, with the branch pipes at the same height. The main water distribution pipe 4 for eliminating fog is on top, and the main water distribution pipe 5 for regular water distribution is on the bottom.

[0067] In winter mode, the defogging water distribution main pipe 4 is running, and the hot channel of the heat exchange component is filled with water. The regular water distribution main pipe 5 is stopped, and the cold channel of the heat exchange component is not filled with water.

[0068] In summer mode, both the defogging water distribution main pipe 4 and the regular water distribution main pipe 5 are in operation, and water is flowing through both the hot and cold channels of the heat exchange components.

[0069] Example 5,

[0070] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the anti-fog water distribution main pipe 4 and the conventional water distribution main pipe 5 are located on both sides of the tower body.

[0071] In winter mode, the defogging water distribution main pipe 4 is running, and the hot channel of the heat exchange component is filled with water. The regular water distribution main pipe 5 is stopped, and the cold channel of the heat exchange component is not filled with water.

[0072] In summer mode, both the defogging water distribution main pipe 4 and the regular water distribution main pipe 5 are in operation, and water is flowing through both the hot and cold channels of the heat exchange components.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
