Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of fiberglass cooling towers, specifically to a counter-flow closed-loop fiberglass cooling tower. Background Technology

[0002] Cooling towers play a crucial role in industrial production and various fields requiring heat dissipation and cooling. Among them, counter-flow closed-circuit FRP cooling towers are widely used due to their excellent performance. However, current counter-flow closed-circuit FRP cooling towers on the market have many drawbacks, with problems particularly prominent in terms of exhaust.

[0003] On the one hand, existing cooling towers have a lack of centralized exhaust. During operation, the hot air generated by a cooling tower needs to be exhausted to achieve cooling. However, many cooling towers have poorly designed exhaust structures, with haphazardly distributed or irregularly shaped exhaust ports, resulting in dispersed exhaust airflow that fails to form a concentrated airflow. This makes it easy for the exhausted hot air to form turbulence around the cooling tower, and some of the hot air may even be re-drawn into the cooling tower, causing hot air circulation and greatly reducing heat dissipation efficiency.

[0004] On the other hand, low exhaust efficiency is a common problem. Some cooling towers have insufficient fan power, failing to provide enough power to quickly expel hot air. Simultaneously, the internal airflow design of the cooling towers lacks optimization, resulting in high airflow resistance. For example, narrow airflow ducts and excessive bends hinder the smooth exhaust of hot air and prolong its residence time within the tower.

[0005] Uncontrolled and inefficient exhaust directly leads to heat buildup inside the cooling tower. Excessively high internal temperatures severely impact cooling efficiency. In industrial production scenarios with extremely high cooling requirements, such as chemical and power industries, poor cooling can cause equipment instability, increase equipment wear and tear, and even lead to safety accidents. Furthermore, sustained high temperatures accelerate the aging of the fiberglass material, shortening the cooling tower's lifespan and increasing operating costs for businesses.

[0006] With the rapid development of industry and the increasing demands for energy conservation and emission reduction, it is imperative to develop a counter-flow closed-loop FRP cooling tower that can centrally exhaust air, improve exhaust efficiency, and prevent internal temperature buildup. This will not only help improve the stability and safety of industrial production but also reduce energy consumption and enterprise costs, promoting the sustainable development of related industries. Utility Model Content

[0036] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0037] like Figures 1-5 As shown, it illustrates a counter-flow closed-loop fiberglass cooling tower according to an embodiment of the present disclosure, comprising:

[0038] The housing 1 and a pair of exhaust fans 2 are both located on the top of the housing 1;

[0039] Exhaust assembly 4, which is disposed inside the housing 1;

[0040] Cooling component 3 is disposed inside the housing 1;

[0041] The cooling assembly 3 includes a pair of connecting pipes 3-1, both of which are disposed on the inner surface of the outer casing 1. One end of each connecting pipe 3-1 is located outside the outer casing 1. Inside the outer casing 1, a pair of side plates 3-2 are disposed, with a large gap between the side plates 3-2 and the inner wall of the outer casing 1. A cavity plate 3-3 is connected between the side plates 3-2, and both ends of the cavity plate 3-3 are connected to the connecting pipes 3-1. A through hole 3-4 is formed on the surface of the cavity plate 3-3, and the through hole 3-4 is not connected to the interior of the cavity plate 3-3. A water inlet pipe 3-5 is rotatably connected inside the outer casing 1. Several dispersion holes 3-6 are opened at the bottom of the water inlet pipe 3-5. A driven gear 3-7 is provided at one end of the water inlet pipe 3-5. The driven gear 3-7 is located outside the outer casing 1. A pair of connecting plates 3-8 are provided outside the outer casing 1. A transmission shaft 3-9 is rotatably connected between the connecting plates 3-8. The transmission shaft 3-9 is rotated by a motor. Several drive gears 3-10 are provided on the transmission shaft 3-9. The drive gears 3-10 mesh with the driven gear 3-7.

[0042] In some examples, in the actual operation of counter-flow closed-loop FRP cooling towers, a cooling component 3 is designed to solve the liquid cooling problem. A pair of connecting pipes 3-1 in this component are located on the inner surface of the outer shell 1, with one end extending to the outside of the outer shell 1. Their function is to introduce the liquid to be cooled, allowing it to flow into the cavity. A pair of side plates 3-2 inside the outer shell 1 have a large gap between them and the inner wall of the outer shell 1. The cavity plate 3-3 connecting the side plates 3-2 is connected at both ends to the connecting pipes 3-1, providing a flow channel for the liquid to be cooled. The through holes 3-4 on the surface of the cavity plate 3-3 are not connected to the interior of the cavity plate 3-3, preventing the liquid to be cooled from mixing with the low-temperature water while allowing heat to be transferred through the through holes 3-4. A water inlet pipe is rotatably connected inside the outer shell 1. The bottom of the 3-5 has several dispersion holes 3-6. When low-temperature water enters the inlet pipe 3-5, it will spray downwards through the dispersion holes 3-6 and evenly cover the cavity plate 3-3. The driven gear 3-7 at one end of the inlet pipe 3-5 is outside the outer shell 1 and meshes with the drive gear 3-10 on the transmission shaft 3-9 that is rotatably connected to the connecting plate 3-8 outside the outer shell 1. The transmission shaft 3-9 is controlled to rotate by a motor. When the motor starts, the transmission shaft 3-9 drives the drive gear 3-10 to rotate. The drive gear 3-10 meshes with the driven gear 3-7 to make the inlet pipe 3-5 rotate, so that the low-temperature water can more evenly cover the cavity plate 3-3 and cool the liquid to be cooled inside the cavity plate 3-3 through the through hole 3-4, effectively improving the heat exchange efficiency.

[0043] Through the coordinated operation of components such as connecting pipe 3-1, side plate 3-2, cavity plate 3-3, through hole 3-4, water inlet pipe 3-5, dispersion hole 3-6, driven gear 3-7, connecting plate 3-8, transmission shaft 3-9 and drive gear 3-10, the cooling assembly 3 achieves efficient cooling of the liquid to be cooled.

[0044] like Figures 1-5 As shown in the figure, the exhaust assembly 4 in this embodiment includes an inner pipe 4-1, which is disposed inside the outer shell 1. The air inlet end of the inner pipe 4-1 is located at the bottom of the cavity plate 3-3. A plurality of auxiliary fans 4-2 are installed in the inner pipe 4-1, and an air hole 4-3 is opened at the top of the inner pipe 4-1.

[0045] In some examples, during the operation of a counter-flow closed-loop FRP cooling tower, an exhaust assembly 4 is designed to address the issue of internal heat buildup affecting cooling efficiency. The inner pipe 4-1 of this assembly is located inside the outer shell 1, with its inlet end at the bottom of the cavity plate 3-3. This allows for timely collection of heat generated near the cavity plate 3-3 during cooling. Several auxiliary fans 4-2 installed in the inner pipe 4-1 provide the power for the heat flow; upon startup, they generate suction, accelerating the flow of heat within the inner pipe 4-1. The vent 4-3 at the top of the inner pipe 4-1 serves as a channel for heat exhaust, allowing the heat to be quickly expelled from the outer shell 1. When the cooling assembly 3 is operating, the low-temperature water outside the cavity plate 3-3 absorbs heat and heats up, generating heat. This heat is drawn in by the inlet end of the inner pipe 4-1 and, under the action of the auxiliary fans 4-2, quickly passes through the inner pipe 4-1 and is discharged from the cooling tower through the top vent 4-3.

[0046] Through the coordinated operation of components such as the internal pipe 4-1, auxiliary fan 4-2, and air vent 4-3, the exhaust assembly 4 effectively accelerates the discharge of internal hot air, maintains a good air circulation environment inside the cooling tower, ensures the continuous and stable operation of the cooling assembly 3, and improves the overall cooling performance and operating efficiency of the counter-flow closed-loop fiberglass cooling tower.

[0047] For example, such as Figure 4 As shown, the cavity plate 3-3 is S-shaped and repeatedly coiled between the side plates 3-2.

[0048] In some examples, the S-shaped structure increases the flow of the liquid to be cooled in the chamber plate 3-3, prolongs the residence time, and improves the cooling effect.

[0049] For example, such as Figure 2 As shown, the air inlet end of the inner pipe 4-1 bends downwards for transition.

[0050] In some examples, a downward-bending transition structure prevents water from entering the inner pipe 4-1.

[0051] For example, such as Figure 3 As shown, a water collection tank 5 is provided at the bottom of the outer shell 1, and a drain pipe 6 is provided on the outside of the outer shell 1. The drain pipe 6 is connected to the inside of the water collection tank 5.

[0052] In some examples, by providing a water collection tank 5 and a drain pipe 6, the cooled water can be collected in a concentrated manner and discharged outward through the drain pipe 6, making it easy to recycle.

[0053] For example, such as Figure 2 As shown, a baffle 7 is provided on the top of the cavity plate 3-3, and the baffle 7 has an inclined structure.

[0054] In some examples, a shield 7 is provided to increase the shielding effect and ensure that the low-temperature water under the spray can completely cover the cavity plate 3-3.

[0055] For example, such as Figure 1 As shown, both the driving gear 3-10 and the driven gear 3-7 are bevel gears with 90° transmission.

[0056] In some examples, a 90° transmission angle enables multiple drive gears 3-10 and driven gears 3-7 to be driven synchronously.

[0057] In actual use: Install the cooling tower in a suitable position, connect the external pipes, start the motor to drive the drive shaft 3-9 to rotate, drive the gear 3-10 to mesh with the driven gear 3-7 to make the water inlet pipe 3-5 rotate, and low temperature water is sprayed onto the cavity plate 3-3 through the dispersion hole 3-6 of the water inlet pipe 3-5. The liquid to be cooled enters the cavity plate 3-3 through the connecting pipe 3-1, flows in the cavity plate 3-3 and exchanges heat with the low temperature water. The hot air generated when the cooling component 3 is working is collected at the air inlet end of the inner pipe 4-1 at the bottom of the cavity plate 3-3. The auxiliary fan 4-2 is started to discharge the hot air through the air hole 4-3 at the top of the inner pipe 4-1. The cooled water falls into the water collection tank 5 and is discharged through the drain pipe 6 for circulation.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
