Description

Technical Field

[0001] This utility model relates to the field of cooling tower packing technology, specifically to the internal flow guiding structure of anti-fogging packing. Background Technology

[0002] A condensing-type defogging and water-saving cooling tower uses a gas-liquid heat exchange component (usually a water-spraying packing assembly) for gas-liquid contact heat exchange between dry, cold air and circulating water to cool the circulating water, producing humid, hot air after the heat exchange. An air-to-air heat exchange component, positioned above the water-spraying packing, is used to eliminate white fog. This component has different channels, allowing for indirect heat exchange between the humid, hot air generated from the gas-liquid heat exchange within the tower and the dry, cold air outside the tower. The nearly saturated humid, hot air inside the tower cools down after passing through the air-to-air heat exchange component, and some water vapor condenses and flows back into the cooling tower, achieving water conservation. The dry, cold air outside the tower warms up after passing through the air-to-air heat exchange component. The air inside and outside the tower mixes after passing through the air-to-air heat exchange component, reducing the relative humidity of the air exiting the tower and making it less prone to white fog formation at the outlet, thus achieving defogging.

[0003] A prior art patent, CN118361993B, discloses a scheme comprising alternating first and second plates forming 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, comprises 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 of the bottom end 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 of the top end of the component, and the two outlets are located on the two sides of the bottom quarter-width section of the component block. This design achieves defogging and circulating water cooling, enabling complete defogging even in low-temperature environments such as winter. It also reduces resistance within the tower and the component's flow channels, minimizing ineffective heat exchange areas and increasing 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 packing material's functional zones are limited by the connection structure, which makes it impossible to guarantee the uniformity of water flow and the thermal performance of the new anti-fogging packing material.

[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 an internal flow guiding structure for anti-fogging packing, which solves the problem that the functional areas of existing packings are limited by the connection structure, making it impossible to guarantee the uniformity of water flow and the thermal performance of the new anti-fogging packing.

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

[0009] The internal flow guiding structure of the anti-fogging packing includes a heat exchange module, which comprises, from top to bottom, an upper flow guiding zone, an anti-fogging heat exchange zone, a lower flow guiding zone, and a reinforcement zone.

[0010] The upper guide zone is connected to an upper guide plate, and the lower guide zone is connected to a lower guide plate. The upper guide plate and the lower guide plate are provided with water guiding and positioning protrusions. The upper guide plate is provided with a diffusion guide structure, and the lower guide plate is provided with a convergence guide structure.

[0011] As an optimized solution, several vertically arranged upper guide sections are arranged side by side in the upper guide zone. These upper guide sections are arranged side by side in the horizontal direction and are located above the inlet of the defogging heat exchange zone.

[0012] As an optimized solution, the upper guide vane is provided with oblique connecting sections located on both sides of the diffuser-type guide structure.

[0013] As an optimized solution, the lower guide zone is provided with several downward vertical guide sections arranged obliquely side by side on both sides of the convergent guide structure.

[0014] As an optimized solution, the diffusion-type flow guiding structure includes several upper corrugated structures arranged in parallel, and the spacing between the upper ends of the several upper corrugated structures is smaller than the spacing between the lower ends of the several upper corrugated structures.

[0015] As an optimized solution, the convergent flow guiding structure includes several lower corrugated structures arranged in parallel, and the spacing between the upper ends of the several lower corrugated structures is greater than the spacing between the lower ends of the several lower corrugated structures.

[0016] As an optimized solution, the lower guide zone is provided with two inclined corrugated structures in the area below the lower vertical guide section.

[0017] As an optimized solution, the lower guide zone is located on both sides of the lower guide vane and has several irregularly distributed lower protruding positioning points.

[0018] As an optimized solution, the upper guide zone is provided with several upper protruding positioning points arranged side by side in the area above the upper guide plate.

[0019] As an optimized solution, guide ribs are provided at the middle positions of the defogging heat exchange zone, the lower guide zone, and the reinforcement zone.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] By setting water-guiding and positioning protrusions in the upper and lower guide zones, the strength of the packing in the planar area is enhanced, the deformation during packing molding is reduced, the heat exchange area is increased, and water guiding function is achieved.

[0022] The diffuser structure is narrow at the top and wide at the bottom, with the inlet connected at the top and the demisting heat exchange zone connected at the bottom, which diffuses the water flowing in from the middle.

[0023] The convergent flow guiding structure is a "wide at the top and narrow at the bottom" structure. The upper part connects to the anti-fogging heat exchange zone, and the lower part connects to the reinforcement zone. It directs the outflowing water to both sides to converge and discharge, and achieves the effect of cross heat exchange and anti-fogging.

[0024] The upper and lower corrugated structures, with continuous corrugations, reduce the water flow velocity, disperse the water flow, and keep the falling water in a splashing state; this improves the stability of the flow channel and stabilizes the flow channel shape.

[0025] The independent placement of guide vanes in the upper and lower guide areas can overcome the problem of difficulty in mold opening caused by the one-piece molding of the main piece.

[0026] The upper guide vane corresponds one-to-one with the flow channel of the defogging heat exchange zone, so that the water flow from the drain outlet can flow evenly into each flow channel, with a water-draining effect of a to 2a; the lower guide vane collects the water flow from the defogging heat exchange zone to the reinforcement zone through the water-collecting effect, with a water-collecting effect of 2b to b.

[0027] A guide rib is provided in the middle position to enhance the stability and balance of the packing. After the packing is bonded into blocks, this rib forms a "barrier" in the hot channel through mirror bonding, which disperses the phenomenon of concentrated water spray in the middle. In the cold channel, this rib forms a middle flow channel, so that the water droplets are evenly distributed across the entire cross section.

[0028] The guide ribs divide the packing into two parts, releasing stress and achieving a smooth overall packing effect. This solves the problems of excessively wide packing, irregular forming between functional areas, and stress deformation along the packing ripples. In the hot channel, the guide ribs disperse and distribute water, making the effect of two channels achieve the effect of one spray channel. In the cold channel, the guide ribs, through a cross structure, disperse excessive water flow in the channels on both sides of the ribs, making the effect of three channels achieve the effect of two channels.

Detailed Implementation

[0033] 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.

[0034] like Figure 1 and Figure 2 As shown, it includes a heat exchange module, which comprises, from top to bottom, an upper guide zone 1, an anti-fogging heat exchange zone 2, a lower guide zone 3, and a reinforcement zone 4.

[0035] The upper guide plate 5 is connected to the upper guide zone 1, and the lower guide plate 6 is connected to the lower guide zone 3. The upper guide plate 5 and the lower guide plate 6 are provided with water guiding and positioning protrusions. The upper guide plate 5 is provided with a diffusion guide structure 7, and the lower guide plate 6 is provided with a gathering guide structure 8.

[0036] Vertical positioning protrusions 18 are arranged side by side on the main substrate within the upper guide zone 1, which serve to provide positioning, rapid bonding, and structural reinforcement when the upper guide plate 5 is bonded.

[0037] Several vertically arranged upper vertical guide sections 9 are arranged in parallel within the upper guide zone 1. The upper vertical guide sections 9 are located on the main substrate. The several upper vertical guide sections 9 are arranged in parallel along the horizontal direction and are located above the inlet of the demisting heat exchange zone 2.

[0038] The upper guide vane 5 is provided with oblique connecting sections 10 located on both sides of the diffuser-type guide structure 7.

[0039] The lower guide zone 3 is provided with several lower vertical guide sections 12 arranged obliquely on both sides of the converging guide structure 8.

[0040] The diffuser structure 7 includes several corrugated structures arranged in parallel, with the spacing between the upper ends of the corrugated structures being smaller than the spacing between the lower ends of the corrugated structures.

[0041] The convergent flow guiding structure 8 includes several lower corrugated structures arranged in parallel, and the spacing between the upper ends of the several lower corrugated structures is greater than the spacing between the lower ends of the several lower corrugated structures.

[0042] The lower guide zone 3 is located below the lower vertical guide section 12 and has two inclined corrugated structures 14 arranged side by side.

[0043] The lower guide zone 3 is located on both sides of the lower guide vane 6 and has several irregularly distributed lower protruding positioning points 13.

[0044] The upper guide zone 1 has several upper protruding positioning points 11 arranged side by side in the area above the upper guide plate 5.

[0045] A guide rib 15 is provided in the middle of the defogging heat exchange zone 2, the lower guide zone 3 and the reinforcement zone 4.

[0046] The guide vanes are arranged in pairs facing each other, with the raised corrugated structures connected to each other.

[0047] The guide rib 15 is formed by connecting the long strip-shaped vertical protrusions on the main plate. The corresponding long strip-shaped vertical protrusions on the main plate are connected to form ribs, while the grooves on the reverse side form a flow channel.

[0048] The working principle of this device is as follows:

[0049] By setting water-guiding and positioning protrusions in the upper guide zone 1 and the lower guide zone 3, the strength of the packing in the planar area is enhanced, the deformation during packing molding is reduced, the heat exchange area is increased, and it has the function of guiding water.

[0050] The diffuser structure 7 is a "narrow at the top and wide at the bottom" structure, with the upper part connected to the water inlet and the lower part connected to the demisting heat exchange zone 2, which diffuses the water flow in the middle.

[0051] The convergent flow guiding structure 8 is a "wide at the top and narrow at the bottom" structure. It connects to the anti-fogging heat exchange zone 2 at the top and the reinforcing zone 4 at the bottom, which directs the outflowing water to both sides to converge and discharge, and achieves the effect of cross heat exchange and anti-fogging.

[0052] The upper and lower corrugated structures, with continuous corrugations, reduce the water flow velocity, disperse the water flow, and keep the falling water in a splashing state; this improves the stability of the flow channel and stabilizes the flow channel shape.

[0053] Independent guide vanes are set in the upper guide zone 1 and the lower guide zone respectively, which can overcome the problem of difficult mold opening caused by the one-piece molding of the main piece;

[0054] The upper guide vane 5 corresponds one-to-one with the flow channel of the defogging heat exchange zone 2, so that the water flow from the drain outlet can flow evenly into each flow channel, with a water-draining effect of a to 2a; the lower guide vane 6 collects the water flow from the defogging heat exchange zone 2 to the strengthening zone 4 through the water-collecting effect, with a water-collecting effect of 2b to b.

[0055] A guide rib 15 is provided in the middle position to enhance the stability and balance of the packing. After the packing is bonded into blocks, this rib forms a "barrier wall 16" in the hot channel through mirror bonding, which disperses the phenomenon of concentrated water spray in the middle. In the cold channel, this rib forms a middle flow channel 17, so that the water is evenly distributed across the entire cross section.

[0056] The guide rib 15 divides the packing into two parts, releasing stress and achieving a smooth overall effect. This solves the problems of excessively wide packing, irregular forming between functional areas, and stress deformation along the packing ripples. In the hot channel, the guide rib 15 disperses and distributes water, making the central spray channel achieve the effect of two channels. In the cold channel, the guide rib 15, through its cross structure, disperses excessive water flow in the channels on both sides of the rib, making the two channels achieve the effect of three channels.
