Abstract
Description
Technical Field
[0001] This utility model relates to the field of air-cooled tower technology, and in particular to an auxiliary cooling device for an indirect cooling tower. Background Technology
[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.
[0003] An indirect air-cooled tower is a heat exchange device primarily used for fluid cooling in industrial processes. It utilizes a closed-loop system where hot water or process fluids flow within finned metal tubes (i.e., cooling triangles), while air flows over these tubes externally, thus transferring heat. The cooling triangles not only significantly increase the heat exchange area and efficiency by acting as a heat exchange interface, but their unique design also promotes airflow, ensuring that the air absorbs heat evenly and effectively. While indirect air-cooled towers cool hot water by drawing in surrounding air, when the ambient temperature is high (such as in summer or other special environments), the drawn-in air also contains heat, reducing the air's heat exchange efficiency with the hot water and thus affecting practical use. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned shortcomings by providing an auxiliary cooling device for indirect cooling towers, which achieves good heat exchange efficiency even in hot environments.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an auxiliary cooling device for an indirect cooling tower, comprising:
[0006] A cooling triangle, the cooling triangle including a triangular mounting bracket;
[0007] Two heat dissipation sections are respectively installed on two sides of the mounting bracket, and heat dissipation pipes are installed inside the heat dissipation sections for dissipating heat from the medium inside the heat dissipation pipes.
[0008] An air guide assembly is located on the other side of the mounting bracket. The air guide assembly is used to change the direction of airflow and guide the airflow to the two heat dissipation parts.
[0009] A cooling component is located at the center of the mounting bracket. The cooling component can be connected to cooling water and spray it onto each heat dissipation part.
[0010] Furthermore, the mounting bracket has a mounting plate at the middle of its top. The cooling component includes a water guide pipe vertically arranged at the bottom of the mounting plate. A transfer pump is provided on the mounting plate. The output end of the transfer pump is connected to the water guide pipe. Multiple nozzles connected to the water guide pipe are provided on the water guide pipe. The output end of each nozzle faces the corresponding heat dissipation part. The input end of the transfer pump can be connected to an external cooling water source and guide the cooling water into the water guide pipe so that the cooling water is sprayed from each nozzle onto the corresponding heat dissipation part.
[0011] Furthermore, the heat dissipation unit includes a rectangular frame, and the heat dissipation pipe passes through the frame. The heat dissipation pipe is used to guide external hot water into the cooling triangle and to guide cooled water out of the cooling triangle. Multiple fins are arranged laterally on the frame, and there are gaps between each fin to allow air to pass through. The heat dissipation pipe contacts each fin, and each fin is arranged in an inclined shape, with its higher side facing the outside of the cooling triangle and its lower side facing the center of the cooling triangle.
[0012] Furthermore, each of the fins is vertically provided with a baffle on its higher side. The baffle is used to prevent cooling water from splashing outside the cooling triangle. A vent is provided on the upper side of the baffle, allowing air to pass through.
[0013] Furthermore, a collection assembly is provided on the lower side of the mounting bracket. The collection assembly includes a collection container located at the bottom of each of the heat dissipation parts. The top of the collection container is open, and the bottom of the water guide pipe is connected to the inner bottom wall of the collection container. A drain outlet communicating with the interior is provided on the upper side of the collection container. The collection container can collect the cooling water flowing down from the lower side of the fins and allow it to settle. The settled water is discharged from the drain outlet.
[0014] Furthermore, the mounting bracket is provided with two inclined guide plates, each of which is located at the bottom of the two heat dissipation parts. The inclined side of the guide plate faces the collection container, which is used to guide the cooling water flowing down the fins and into the collection container.
[0015] Furthermore, the air guide assembly includes a mounting frame mounted on a mounting bracket, on which a plurality of air guide vanes are vertically and rotatably mounted, the air guide vanes being distributed in a straight line at equal intervals, and a driving device is mounted on the mounting frame for driving each air guide vane to rotate.
[0016] The beneficial effects of this utility model are reflected in:
[0017] In this invention, when the ambient temperature is suitable, only air is allowed to enter the cooling triangle to exchange heat with the hot water in the heat dissipation section. After the air exits from the cooling triangle, it is discharged from the top of the indirect air-cooled tower from bottom to top. When the ambient temperature is high, the cooling component is activated, and the cooling component is connected to the cooling water and sprays the cooling water onto each heat dissipation section, thereby further reducing the temperature of the heat dissipation section. This increases the heat exchange efficiency with the hot water in the heat dissipation section, giving the indirect air-cooled tower a better cooling effect. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.
[0027] Please see Figure 1-6This utility model discloses an auxiliary cooling device for an indirect cooling tower, including a cooling triangle, which includes a triangular mounting bracket 1. A heat dissipation part 2 is installed on two sides of the mounting bracket 1. A heat dissipation pipe 22 is installed inside the heat dissipation part 2. The heat dissipation part 2 is used to dissipate heat from the medium inside the heat dissipation pipe 22.
[0028] In one embodiment, an air guide component 3 is provided on the other side of the mounting bracket 1. The air guide component 3 is used to change the direction of airflow and guide the airflow to the two heat dissipation parts 2. A cooling component 4 is vertically provided at the center of the mounting bracket 1. The cooling component 4 can be connected to cooling water and spray it onto each heat dissipation part 2.
[0029] In practice, when the ambient temperature is suitable, only air is allowed to enter the cooling triangle to exchange heat with the hot water in the heat dissipation section 2. After the air is discharged from the cooling triangle, it is discharged from the top of the indirect air-cooled tower from bottom to top. When the ambient temperature is high, the cooling component 4 is activated, which connects to the cooling water and sprays the cooling water onto each heat dissipation section 2, thereby further reducing the temperature of the heat dissipation section 2. This increases the heat exchange efficiency of the hot water in the heat dissipation section 2, giving the indirect air-cooled tower a better cooling effect.
[0030] In one embodiment, the mounting bracket 1 has a mounting plate at the middle of its top. The cooling component 4 includes a water pipe 41 vertically mounted on the bottom of the mounting plate. A transfer pump 42 is mounted on the mounting plate. The output end of the transfer pump 42 is connected to the water pipe 41. A plurality of nozzles 43 connected to the water pipe 41 are mounted on the water pipe 41. The output end of each nozzle 43 faces the corresponding heat dissipation part 2.
[0031] In practice, when it is necessary to cool the heat dissipation section 2 with cooling water, an external pipe can be used to connect to the cooling water source. The external pipe is connected to the input end of the transfer pump 42. When in use, the transfer pump 42 is started, so that the cooling water passes through the external pipe and the transfer pump 42 and enters the water guide pipe 41. The cooling water is finally sprayed from each nozzle 43 onto the corresponding heat dissipation section 2, thereby reducing the temperature of the heat dissipation section 2 and thus further improving the heat exchange efficiency with hot water.
[0032] In one embodiment, the heat dissipation unit 2 includes a rectangular frame 21, which is mounted on a mounting bracket 1. A heat dissipation pipe 22 is inserted into the frame 21 and passes through the frame 21. The heat dissipation pipe 22 is used to guide external hot water into the cooling triangle and to guide cooled water out of the cooling triangle. A plurality of fins 23 are horizontally mounted on the frame 21, and there are gaps between each fin 23 to allow air to pass through. The heat dissipation pipe 22 contacts each fin 23. Each fin 23 is arranged in an inclined shape, with its higher side facing the outside of the cooling triangle and its lower side facing the center of the cooling triangle.
[0033] In practice, when hot water is transferred inside the heat dissipation pipe 22, its heat is transferred to each fin 23, thereby increasing the heat conduction area. Air passes through each fin 23, thereby carrying away heat from the heat dissipation part 2, thus cooling the hot water. Since the fins 23 are inclined and their lower side is close to the center of the cooling triangle, when the cooling component 4 sprays water onto the heat dissipation part 2, the water adheres to the fins 23 to cool them down. Furthermore, the water flows along the inclined direction of the fins 23 to the lower side inside the cooling triangle, instead of splashing out of the cooling triangle.
[0034] In one embodiment, a baffle 24 is vertically installed on one side of the height of each fin 23. The baffle 24 is used to prevent cooling water from splashing outside the cooling triangle. A vent 25 is provided on the upper side of the baffle 24, which allows air to pass through.
[0035] In practice, since air passes through the gaps between the fins 23 and exits the cooling triangle, it can easily blow the cooling water attached to the fins 23 out of the cooling triangle. The baffle 24 can effectively block the splashing of cooling water. The cooling water can only flow to the lower part of the cooling triangle in the tilt direction of the fins 23. In addition, since the vent 25 is provided, air can also pass through the vent 25 naturally, thus ensuring that the baffle 24 will not affect the normal airflow.
[0036] In one embodiment, a collection component 5 is provided on the lower side of the mounting bracket 1. The collection component 5 includes a collection container 51 located at the bottom of each heat dissipation part 2. Specifically, there is a hollow section on the lower side of the mounting bracket 1 where the heat dissipation part 2 is not provided. The collection container 51 is detachably installed there, with its top open. The bottom of the water guide pipe 41 is connected to the inner bottom wall of the collection container 51. A drain outlet 52 communicating with the interior is provided on the upper side of the collection container 51. The collection container 51 can collect the cooling water flowing down from the lower side of the fins 23 and allow it to settle. The settled water is discharged from the drain outlet 52.
[0037] In practice, the cooling water on each fin 23 flows along the inclined direction of the fin 23. After flowing directly down, it passes through the open part of the collection container 51 and enters it. Since the surface of the heat dissipation part 2 is prone to dust and other impurities during long-term use, the cooling water sprayed on the heat dissipation part 2 can also play a cleaning role. The impurities flow into the collection container 51 with the water. As the liquid level of the cooling water inside the collection container 51 rises, the impurities will settle. When the liquid level exceeds the drain outlet 52, the clean water will flow out through the drain outlet 52. The staff can use an external pipe to guide the clean water to the discharge location and clean the impurities inside the collection container 51 regularly. The clean water can still be used for cooling after subsequent treatment and cooling, thus reducing resource waste.
[0038] In one embodiment, the mounting bracket 1 is provided with two inclined guide plates 6, each guide plate 6 is located at the bottom of the two heat dissipation parts 2, and the inclined lower side of the guide plate 6 faces the collection container 51.
[0039] With this design, the inclined guide plate 6 can guide the cooling water flowing down the fins 23 and into the collection container 51, thereby ensuring that the cooling water can be accurately collected and treated.
[0040] In one embodiment, the air guide assembly 3 includes a detachable mounting bracket 31 mounted on the mounting bracket 1. A plurality of air guide vanes 32 are vertically and rotatably mounted on the mounting bracket 31. The air guide vanes 32 are distributed in a straight line at equal intervals. A drive device 33 is mounted on the mounting bracket 31.
[0041] In specific implementation, the driving device 33 can be a motor, multiple transmission wheels, and a transmission belt mounted on each transmission wheel. Each transmission wheel is coaxially mounted on the top of the corresponding air guide 32. In use, by starting the motor, in conjunction with each transmission wheel and transmission belt, each air guide 32 can be driven to rotate. The rotation adjustment of each air guide 32 can adjust the direction of airflow into the cooling triangle, so that the air flows evenly to each heat dissipation part 2. In actual cases, two sets of air guide components 3 can be set, which guide the air evenly through each heat dissipation part 2 according to the different positions of the heat dissipation parts 2.
[0042] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
[0043] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
[0044] Additionally, "multiple" refers to two or more.
