Description

Technical Field

[0001] This utility model relates to the field of cooling tower packing technology, specifically to the structure of the heat exchange enhancement zone of a heat exchange module. Background Technology

[0002] Cooling towers are commonly used heat dissipation equipment in industrial production. Their efficiency and environmental performance have always been the focus of industry attention. Their function is to exchange heat between circulating water carrying waste heat and the air inside the tower, transferring the heat of the water to the air and dissipating it into the atmosphere, thereby cooling the circulating water.

[0003] As industrialization accelerates, factories are demanding more and more water for cooling, resulting in a growing number of cooling towers. During winter, these towers generate a lot of water mist, leading to significant water consumption. Furthermore, the mist drifts with the wind, severely impacting the environmental conditions downwind.

[0004] The defogging packing adopts a modular design, with separate hot and cold channels and a special flow channel design. Each piece has a water channel and an air channel on its front and back, respectively, which gives it a good defogging effect and can effectively eliminate the white fog generated by industrial water and heat exchange.

[0005] A prior art patent, CN119687714A, discloses a solution comprising A1 packing sheet, B1 packing sheet, A2 packing sheet, B2 packing sheet, a cold air chamber, a hot air chamber, a bonding surface, an exhaust port, reinforced bonding points, a straight segment of the packing guide waveform, an arc segment of the packing guide waveform, and a heat dissipation wave of the packing waveform. This anti-fogging packing possesses the mass transfer and heat dissipation effects of traditional packing while meeting the requirements for anti-fogging. This packing eliminates the need for an anti-fogging module, thereby reducing the overall height of the cooling tower and lowering its construction costs. By combining the packing sheets, a dry cold air chamber and a humid hot air chamber are formed. The dry cold air chamber cools the humid hot air chamber, causing water in the saturated air to condense, achieving water conservation. The dry cold air then combines with the humid hot air to form unsaturated air, which is discharged from the cooling tower, achieving the purpose of anti-fogging, improving the quality of the surrounding environment, and meeting environmental protection requirements.

[0006] The shortcomings of existing technology have gradually become apparent with use, mainly in the following aspects:

[0007] Existing packing materials are limited by internal flow channels, resulting in a large ineffective area, which affects the flow rate of air intake and water discharge. Furthermore, the mixing of water discharge areas in hot and cold channels affects the defogging and cooling effect of the packing materials.

[0008] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a heat exchange enhancement zone structure for a heat exchange module. This structure solves the problem that existing packing materials are limited by internal flow channels, resulting in a large ineffective area that affects the flow rate of air intake and water runoff. Furthermore, the mixing of water runoff in the hot and cold channels affects the demisting and cooling effect of the packing materials.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] The heat exchange module heat exchange enhancement zone structure includes an anti-fogging packing body. The lower end of the anti-fogging packing body is provided with a heat exchange enhancement zone. The heat exchange enhancement zone includes several groups of flaps arranged in parallel along the longitudinal direction. Each group of flaps includes two oppositely arranged wavy flaps. Several effective heat exchange cavities are formed in the transverse direction between the trough and crest sections of the two wavy flaps. Several ineffective heat exchange cavities are formed in the transverse direction between adjacent groups of flaps. The cross-sectional area of ​​the effective heat exchange cavities is larger than the cross-sectional area of ​​the ineffective heat exchange cavities.

[0012] As an optimized solution, the heat-strengthening ring reinforcement area is divided into several independently configured channels by the parallel sealing ridges.

[0013] As an optimized solution, the grooves formed by the sealing ridge and the wavy flap on both sides are filled with a waterproof and weather-resistant filler.

[0014] As an optimized solution, the channel is divided into symmetrically arranged hot channel, cold channel, cold channel and hot channel along the transverse direction.

[0015] As an optimized solution, the sealing ridge is provided with a hot channel sealing ridge edge corresponding to the hot channel.

[0016] As an optimized solution, the sealing ridge is provided with a cold channel sealing ridge edge corresponding to the cold channel.

[0017] As an optimized solution, the trough and crest sections of the two wave-shaped flaps in the same group are arranged opposite each other to form the effective heat exchange cavity.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] The wavy lines in the bottom heat exchange reinforcement zone reduce the area of ​​the ineffective zone as much as possible while ensuring stability by changing the height of the connection points (i.e., the smoothness of the crests and troughs). This increases the air inlet area, increases the air volume of the packing, and enhances the thermal performance of the new anti-fogging packing. The bottom heat exchange reinforcement zone of the heat exchange module enhances the effective zone by reducing the useless wavy lines through a corrugated structure design.

[0020] The grooves formed by the sealing ridge and the wavy flap are filled with waterproof and weather-resistant filler. The back of the protrusion is filled with waterproof and weather-resistant material to achieve a flat effect, which avoids water accumulation on the back of the protrusion and makes the water droplets on the back of the protrusion more even.

[0021] The heat exchange enhancement zone extends the sealing ridge completely to the edge of the packing, completely isolating the cold channel from the hot channel and preventing air leakage; it achieves a complete sealing effect, thus creating a boundary between the cold and hot channels of the packing.

Detailed Implementation

[0029] 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.

[0030] like Figures 1 to 5As shown, it includes an anti-fogging packing body 1. The lower end of the anti-fogging packing body 1 is provided with a heat exchange enhancement zone 2. The heat exchange enhancement zone 2 includes several groups of folds arranged in parallel along the longitudinal direction. Each group of folds includes two oppositely arranged wavy folds 8. Between the trough and crest sections of the two wavy folds 8, several effective heat exchange cavities 6 are formed in the transverse direction. Between adjacent groups of folds, several ineffective heat exchange cavities 7 are formed in the transverse direction. The cross-sectional area of ​​the effective heat exchange cavity 6 is larger than the cross-sectional area of ​​the ineffective heat exchange cavity 7.

[0031] The heat-reinforced ring reinforcement zone is divided into several independently set channels by the parallel sealing ridges 5.

[0032] The grooves formed by the sealing ridge 5 and the wavy flap 8 are filled with waterproof and weather-resistant filler 9.

[0033] The passage is divided into symmetrically arranged hot passage, cold passage, cold passage and hot passage along the horizontal direction.

[0034] The sealing edge 5 is provided with a corresponding hot channel sealing edge 3.

[0035] The sealing edge 5 is provided with a corresponding cold channel sealing edge 4.

[0036] The trough and crest sections of the two wave-shaped flaps 8 in the same group are arranged opposite each other, forming an effective heat exchange cavity 6.

[0037] The cold aisle sealing edge 4 achieves a complete seal through "mirror" fitting, thereby completely controlling the "water inflow" and "air inflow" within the cold aisle, guiding the water inflow of the entire cold aisle to flow out through the middle of the packing.

[0038] The hot channel sealing edge 3 achieves a complete sealing effect through "mirror" fitting, thereby completely controlling the "water inflow" and "air inflow" within the hot channel, that is, guiding the water inflow of the entire hot channel to flow out on both sides of the packing, forming a water inflow cross effect;

[0039] By extending the cold aisle sealing edge 4 and the hot aisle sealing edge 3 all the way to the bottom edge of the module, and sealing them with the mirror protrusion of the sealing edge 5, the cold and hot aisles of the heat exchange enhancement zone 2 are completely sealed.

[0040] The grooves formed by the sealing ridge 5 and the wavy flap 8 are filled with waterproof and weather-resistant material, making the groove a flat area. Water falling into the filled area flows to the bottom according to gravity. The raised side seals the water flow, thus guiding the water to the designated location.

[0041] The bonding method of the adjacent corrugated flaps 8 located in the heat exchange enhancement zone 2 is the same as that of the existing filler bonding method.

[0042] The working principle of this device is as follows:

[0043] The bottom heat exchange reinforcement zone 2 wavy line reduces the area of ​​the ineffective area as much as possible while ensuring stability by changing the height of the connection point (i.e., the smoothness of the crest and trough). This increases the air inlet area, increases the air volume of the packing, and enhances the thermal performance of the new anti-fogging packing. The bottom heat exchange reinforcement zone 2 of the heat exchange module enhances the effective area by reducing the useless wavy line through the corrugated structure design.

[0044] The grooves formed by the sealing ridge 5 and the wavy flap 8 are filled with waterproof and weather-resistant filler 9. The back of the protrusion is filled with waterproof and weather-resistant material to achieve a flat effect, which avoids water accumulation on the back of the protrusion and makes the water drop on the back of the protrusion more even.

[0045] The heat exchange enhancement zone 2 completely separates the sealing ridge 5 and extends it to the edge of the packing, completely isolating the cold channel from the hot channel and preventing air leakage; it achieves a complete sealing effect, giving the packing a boundary between the cold and hot channels.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. 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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
