Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and in particular to a crossflow cooling tower with concealed inlet and outlet water pipes. Background Technology

[0002] The main ancillary facilities and structures of the subway on the ground include entrances and exits, ventilation shafts, and cooling towers. The design style of entrances and exits is generally uniform. Most ventilation shafts are low-profile and have little impact on the landscape. Subway cooling towers are generally crossflow type and are usually located in the green belts near the station.

[0003] Cooling towers are relatively large. Since the water inlet of the cooling tower's water distributor is typically located at the top, the inlet pipe usually connects to the top distributor via an external riser. The water collection tray is usually located in the middle of the tower's base. This results in insufficient length for installing valves and bypass pipes after the outlet pipe connects to the collection tray. Consequently, valves on both the inlet and outlet pipes are installed outside the tower's projection, making the entire cooling tower appear even larger and more cluttered. To conceal the cooling tower, decorative railings or louvers are typically installed around it, extending 1-2 meters to the same height as the tower, enclosing the tower body, main inlet and outlet pipes, and branch pipes. This further increases the space occupied by the cooling tower and, to some extent, detracts from the landscape. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a crossflow cooling tower with concealed inlet and outlet water pipes.

[0005] This utility model provides a crossflow cooling tower with concealed inlet and outlet water pipes, including:

[0006] The crossflow cooling tower body is installed on a concrete foundation above the ground. Two sets of packing are symmetrically arranged on both sides, forming a cavity structure between the two sets of packing with the top facing the fan. The water distributor is located directly above the packing and connected through a water distribution pipe. The water collection tray is located at the corner of the bottom of the tower body away from the cavity structure.

[0007] An integrated piping system includes an internal water inlet branch pipe and an external water inlet branch pipe connected by a riser pipe through the tower. The internal water inlet branch pipe is laid along the inner wall of the non-filled side and connected to the water distribution pipe. The external water inlet branch pipe and the external water outlet branch pipe are arranged parallel to each other in the space formed by the bottom of the tower and the ground. The external water inlet branch pipe is connected to the buried water inlet branch pipe, and the external water outlet branch pipe is connected to the buried water outlet branch pipe. The buried water inlet branch pipe and the buried water outlet branch pipe are respectively connected to the underground water inlet main pipe and the underground water outlet main pipe.

[0008] Optionally, the water inlet branch pipe inside the tower is connected to the middle of the water distribution pipe.

[0009] Optionally, the water inlet branch pipe outside the tower and the water outlet branch pipe are provided with an electric water valve and a manual water valve, and a bypass branch pipe is provided with the manual water valve.

[0010] Optionally, the net distance between the tower body and the ground is greater than 1.2 meters.

[0011] Optionally, the distance between the water inlet branch pipe outside the tower and the water outlet branch pipe is greater than 0.6 meters and greater than 2n meters, wherein n is the pipe diameter of the water inlet branch pipe outside the tower or the water outlet branch pipe.

[0012] Optionally, the distance between the water inlet branch pipe outside the tower and the water outlet branch pipe is greater than 2n+1 meters, wherein n is the pipe diameter of the water inlet branch pipe outside the tower or the water outlet branch pipe.

[0013] Optionally, it further comprises a decorative panel wrapping the outer facade of the tower body and extending to the ground, a ventilation louver structure is arranged in the filler area, a tower body maintenance door and a tower bottom maintenance door are arranged corresponding to the tower body maintenance door and the pipe valve area respectively; the ventilation louver structure of the decorative panel covers at least the facade height of the filler area, the louver spacing is matched with the filler porosity, and a door leaf with a hidden handle is arranged at the tower bottom maintenance door.

[0014] The embodiments of the present application have the following technical effects:

[0015] The present application adjusts the water pan from the middle of the cooling tower bottom to the corner, which leaves enough space for the water inlet branch pipe outside the tower to enter the cooling tower from the bottom, and also leaves enough space for the water outlet branch pipe to connect the water pan from the bottom. Therefore, the water inlet branch pipe outside the tower and the water outlet branch pipe can be arranged at the bottom and connected with the buried water inlet main pipe and the water outlet main pipe. The entire cooling tower cannot see any pipe valve outside the projection range, which greatly reduces the space occupied by the cooling tower and its attached pipe valves.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantage of the utility model more clear, the technical scheme of the utility model will be described clearly and completely below. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the range of the utility model.

[0025] Figure 1 The utility model provides an inlet and outlet water pipe hidden type cross flow cooling tower first direction side view for the embodiment of the utility model, Figure 2 The utility model provides an inlet and outlet water pipe hidden type cross flow cooling tower second direction side view for the embodiment of the utility model, Figure 3 The utility model provides an inlet and outlet water pipe hidden type cross flow cooling tower third direction side view for the embodiment of the utility model. Specifically, Figures 1-3 All are the side perspective view of the cooling tower along different directions. Refer to Figures 1-3 The utility model provides an inlet and outlet water pipe hidden type cross flow cooling tower, comprising:

[0026] The cross-flow cooling tower body, the tower body (101) of which is installed on the concrete foundation (107) higher than the ground, two groups of fillers (104) are symmetrically arranged on both sides, and a cavity structure is formed between the two groups of fillers (104) and the top of the fan (102) is directly opposite. The water distributor (103) is arranged directly above the filler (104) and is connected through the water distribution pipe (201). The water collecting tray (105) is arranged at the bottom corner of the tower body (101) away from the cavity structure.

[0027] The integrated pipeline system comprises a tower-inlet water branch pipe (202) and a tower-outlet water branch pipe (204) connected through a tower-penetrating vertical pipe (203), the tower-inlet water branch pipe (202) is arranged along the non-filler side inner wall and connected with the water distribution pipe (201). The tower-outlet water branch pipe (204) and the outlet water branch pipe (207) are arranged in parallel in the space formed by the tower bottom and the ground, the tower-outlet water branch pipe is connected with the buried inlet water branch pipe (205), and the outlet water branch pipe (207) is connected with the buried outlet water branch pipe (208). The buried inlet water branch pipe (205) and the buried outlet water branch pipe (208) are respectively connected with the underground laid inlet main pipe (206) and the outlet main pipe (209).

[0028] As shown in Figures 1-3 The cross-flow cooling tower releases the three-dimensional space of the central area of the tower bottom by shifting the traditional centrally arranged water collecting tray (105) to the corner of the tower bottom, while maintaining the original water collecting function. The space reconstruction enables the inlet water pipeline to adopt a unique vertical tower-penetrating structure, the tower-penetrating vertical pipe (202) directly penetrates the tower bottom of the tower body (101), the tower-inlet water branch pipe (202) descends along the non-filler side inner wall and forms a three-dimensional pipe network with the horizontal tower-outlet water branch pipe (204), and the buried inlet main pipe (206) is connected to realize the full concealed layout.

[0029] As described above, the tower-outlet water branch pipe (204) enters the cooling tower from the tower bottom, and the outlet water branch pipe (207) is connected with the water collecting tray (105) from the tower bottom, so that the tower-outlet water branch pipe (204) and the outlet water branch pipe (207) are arranged at the tower bottom and connected with the buried inlet main pipe (206) and the outlet main pipe (209), and any pipeline valve cannot be seen outside the projection range of the entire cooling tower, so that the space occupied by the cooling tower and the auxiliary pipeline valve is greatly reduced, and the cross-flow cooling tower body is square in shape, which is more convenient for peripheral decoration.

[0030] Continuing to refer to Figure 2 In some embodiments, the tower-inlet water branch pipe (202) is connected to the middle part of the water distribution pipe (201).

[0031] Specifically, the pipeline system is particularly designed with a staged pressure balance, and the middle interface of the water inlet branch pipe (202) in the tower ensures uniform distribution of water flow to the water distributors (201) on both sides, which is conducive to improving the evaporation efficiency of water flow through the filler (104).

[0032] Figure 4 A pipeline structure schematic diagram is provided for the embodiments of the utility model. In some embodiments, the water inlet branch pipe (204) and the water outlet branch pipe (207) are provided with an electric water valve (210) and a manual water valve (212), and a bypass branch pipe (211) is installed, and the bypass branch pipe (211) is provided with a manual water valve (212).

[0033] The electric water valve (210) can realize automatic control and remote control of water inlet, and improve the automation characteristics of the cooling tower. By providing the bypass branch pipe (211) and the manual water valve (212), in the case of failure of the electric water valve (210), the bypass branch pipe (211) can be manually switched, and the use of the cooling tower will not be affected due to the damage of the electric water valve (210).

[0034] In some embodiments, the net distance between the tower body (101) and the ground is greater than 1.2 meters.

[0035] In some embodiments, the distance between the water inlet branch pipe (204) and the water outlet branch pipe (207) is greater than 0.6 meters and greater than 2n meters. Wherein, n is the pipe diameter of the water inlet branch pipe (204) or the water outlet branch pipe (207).

[0036] In some embodiments, the distance between the water inlet branch pipe (204) and the water outlet branch pipe (207) is greater than 2n+1 meters. Wherein, n is the pipe diameter of the water inlet branch pipe (204) or the water outlet branch pipe (207).

[0037] Specifically, the larger net distance between the tower body (101) and the ground can provide more operating space for maintenance personnel, making the maintenance process easier. When the water inlet branch pipe (204) is not provided with a bypass branch pipe (211), the distance between the water inlet branch pipe (204) and the water outlet branch pipe (207) can be greater than 0.6 meters and greater than twice the pipe diameter, and the pipe diameter is based on the larger pipe diameter between the water inlet branch pipe (204) and the water outlet branch pipe (207). When the bypass branch pipe (204) is provided, the distance between the two is greater than twice the pipe diameter plus 1m, and the pipe diameter is also based on the larger pipe diameter between the water inlet branch pipe (204) and the water outlet branch pipe (207). Based on the setting, sufficient space can be left between the water inlet branch pipe (204) and the water outlet branch pipe (207) for maintenance.

[0039] Decorative panel (301) can adopt modular design, and the inclination angle of its louver area is optimized through CFD simulation to form visual shielding effect while ensuring air intake.The size of the tower body access door is designed with reference to the size of standard tool kit, and the magnetic sealing strip arranged at the edge of the door leaf can be automatically aligned with the panel lines when closed.This design takes into account both function and aesthetics, so that the equipment can efficiently dissipate heat when running, and perfectly integrate into the architectural landscape when stationary.
