Description

Technical Field

[0001] This utility model relates to the field of cooling equipment technology, and in particular to an open-loop cooling equipment. Background Technology

[0002] In the industrial sector, the production processes of industries such as chemical, power, and metallurgy generate heat from the operation of numerous pieces of equipment, such as chemical reaction vessels, steam turbines of generator sets, and metallurgical furnaces. Cooling equipment is required to maintain suitable temperatures to ensure stable equipment operation and product quality. Open-loop circulating cooling systems are widely used due to their low cost and ease of maintenance to meet the needs of equipment heat dissipation and environmental cooling. Among these, cooling towers are a key component of open-loop circulating cooling systems. Their main function is to dissipate the heat in the circulating water into the atmosphere through heat exchange between water and air, thereby lowering the water temperature and dissipating heat from the cooling system. However, with the expansion of industrial scale and the growth of building demands, the shortcomings of existing equipment have become apparent. On the one hand, their cooling efficiency is significantly constrained by environmental factors. At high temperatures and humidity, water evaporation and heat dissipation are hindered, making it difficult to cool down quickly. On the other hand, open systems lead to serious water waste. Direct contact between water and air causes a large amount of evaporation and wind loss, requiring frequent water replenishment, which not only increases water costs but also contradicts the concept of water conservation, thus necessitating optimization and upgrading. Utility Model Content

[0003] The main objective of this invention is to provide an open-loop cooling device that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An open-loop circulating cooling device includes a bottom pool frame. An operation key is fixedly connected to the middle of the front end of the bottom pool frame. A drain pipe is fixedly connected to the left front end of the bottom pool frame. A cooling tower shell is fixedly connected to the upper left and upper right inner walls of the bottom pool frame. A viewing window is provided at the upper front end of the cooling tower shell. A cooling structure is fixedly connected to the middle inner wall of the cooling tower shell. An axial flow fan is provided at the middle upper end of the cooling tower shell. Six baffles are fixedly connected in a ring array on the upper inner wall of the axial flow fan. A water-saving water spray device is fixedly connected to the lower right end of the bottom pool frame. One end of the water-saving water spray device extends into the cooling tower shell and is located above the cooling structure.

[0006] Preferably, the cooling structure includes a plastic filler block, the left, right, front and rear ends of which are fixedly connected to the inner wall of the cooling tower shell. A number of honeycomb perforated blocks are fixedly connected to the upper end of the plastic filler block, and a number of through-holes are opened at the upper end of the plastic filler block. A heat dissipation component is fixedly connected to the lower left and lower right parts of the plastic filler block.

[0007] By adopting the above technical solution: a plastic filler block is used as the base and fixed to the outer shell of the cooling tower to support the honeycomb hollow block and the drain hole. The honeycomb hollow block increases the contact area between water and air, and the drain hole guides the water flow. The three work together to accelerate heat exchange and improve cooling efficiency.

[0008] Preferably, the honeycomb perforated blocks are arranged in a rectangular array, and the plastic filler blocks are connected to the interior of the cooling tower shell through a number of drainage holes.

[0009] By adopting the above technical solution: the rectangular array of honeycomb hollow blocks is distributed to uniformly expand the heat dissipation surface, and the water outlet is connected to the inside of the tower to ensure that the water flow is evenly distributed. The combination of the two makes the water flow stable, enhances the heat exchange between air and water, and ensures stable cooling effect.

[0010] Preferably, the heat dissipation component includes a composite material filler block, which is fixedly connected to the lower left and lower right parts of the plastic material filler block. A water receiving groove is opened in the middle of the upper part of the composite material filler block, and several Z-shaped water holes that pass through the upper part of the composite material filler block are opened in the upper part.

[0011] By adopting the above technical solution: the filler block of the material receives the water flow, the water receiving tank collects and guides the Z-shaped water holes to extend the water flow path, and the water fully contacts the air in the tortuous channel to dissipate heat, further reducing the water temperature and improving the cooling efficiency.

[0012] Preferably, the Z-shaped water holes are arranged in a rectangular array.

[0013] By adopting the above technical solution: the Z-shaped water hole rectangular array distribution makes the water flow uniformly dispersed in the heat dissipation component. The extended water flow path combined with the uniform distribution increases the heat exchange time and area, thereby enhancing the cooling effect of the heat dissipation component.

[0014] Preferably, the water-saving water spraying device includes a circulating pump. The left end of the circulating pump is fixedly connected to the lower right end of the bottom pool frame via an inlet pipe. The output end of the circulating pump is fixedly connected to a suction pipe. The end of the suction pipe away from the circulating pump extends into the upper part of the cooling tower shell and is fixedly connected to a large annular pipe. A connecting pipe is fixedly connected to the right side of the inner wall of the large annular pipe. A small annular pipe is fixedly connected to the end of the connecting pipe away from the large annular pipe. Several plastic water spray nozzles are fixedly connected to the lower outer surface of both the connecting pipe and the small annular pipe.

[0015] By adopting the above technical solution: the circulating pump drives water circulation, the suction pipe, large and small ring pipes and connecting pipes transport water flow, and the plastic water spray nozzles disperse the water into fine water droplets, accurately distribute water to reduce waste, and improve water utilization and cooling efficiency.

[0016] Preferably, the small annular tube is located above and inside the plastic spray nozzle, and several of the plastic spray nozzles are located directly above the plastic filler block. The design of the small annular tube and nozzle positions ensures that water droplets accurately cover the plastic filler block.

[0017] By adopting the above technical solution—a uniform and fine water spraying method—heat exchange efficiency is enhanced, water waste is reduced, and the overall cooling and water-saving performance of the equipment is improved.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In this utility model, the plastic filler block serves as the basic carrier, providing stable support for each component and a water flow channel. The honeycomb hollow blocks are distributed in a rectangular array, which greatly increases the contact area between water and air, enhancing the heat exchange process. The drain hole guides the water flow to be evenly dispersed, ensuring uniform heat dissipation. The water receiving tank in the heat dissipation component receives the water flow, and the Z-shaped water hole extends the water flow path, allowing water and air to exchange heat fully. The cooperation of all components can effectively overcome the problem of low cooling efficiency of traditional equipment. Even in high temperature and high humidity environments, the multi-layer heat dissipation design can quickly reduce the water temperature, ensuring the stable and efficient operation of the open-loop cooling equipment.

[0020] 2. In this utility model, water is drawn out of the bottom pool frame by a circulating pump and transported to the plastic spray nozzles through a suction pipe, a ring pipe, and a connecting pipe. The water is precisely sprayed onto the packing blocks. The ring pipe design ensures uniform water distribution, avoiding local over- or under-watering and reducing water waste. The nozzles are located directly above the packing blocks, allowing the water flow to concentrate and cover the heat dissipation area, preventing water droplet splashing and loss, and improving water utilization. At the same time, the water circulates in the system, reducing water loss caused by evaporation and wind, lowering the frequency of water replenishment and water costs. This effectively solves the problem of water waste in open cooling systems, conforms to the concept of water conservation, and ensures that cooling efficiency is not affected, achieving a balance between high efficiency and water conservation and cooling performance.

[0029] Please see Figure 1-4 This utility model provides a technical solution:

[0030] An open-type circulating cooling device includes a bottom pool frame 1. An operation key 2 is fixedly connected to the middle of the front end of the bottom pool frame 1. A drain pipe 3 is fixedly connected to the left front end of the bottom pool frame 1. A cooling tower shell 4 is fixedly connected to the upper part of the upper left and upper right inner walls of the bottom pool frame 1. A viewing window 5 is provided at the upper front end of the cooling tower shell 4. A cooling and temperature reduction structure 6 is fixedly connected to the middle of the inner wall of the cooling tower shell 4. An axial flow fan 7 is provided at the middle of the upper end of the cooling tower shell 4. Six baffles 8 are fixedly connected in a ring array on the upper inner wall of the axial flow fan 7. A water-saving water spray device 9 is fixedly connected to the lower right end of the bottom pool frame 1. One end of the water-saving water spray device 9 extends into the cooling tower shell 4 and is located above the cooling and temperature reduction structure 6.

[0031] In this embodiment, the cooling structure 6 includes a plastic filler block 61. The left, right, front, and rear ends of the plastic filler block 61 are fixedly connected to the inner wall of the cooling tower shell 4. A plurality of honeycomb perforated blocks 62 are fixedly connected to the upper end of the plastic filler block 61. A plurality of vertically penetrating drainage holes 63 are opened at the upper end of the plastic filler block 61. A heat dissipation component 64 is fixedly connected to the lower left and lower right parts of the plastic filler block 61. The plurality of honeycomb perforated blocks 62 are rectangular. The plastic packing blocks 61 are connected to the interior of the cooling tower shell 4 through several drainage holes 63. The heat dissipation component 64 includes a composite material packing block 641, which is fixedly connected to the lower left and lower right parts of the plastic packing block 61. A water receiving groove 642 is opened in the middle of the upper part of the composite material packing block 641, and several Z-shaped water holes 643 are opened in the upper part of the composite material packing block 641. The several Z-shaped water holes 643 are arranged in a rectangular array.

[0032] Through the above scheme: water flows through the drain hole 63 onto the plastic filler block 61. The honeycomb perforated blocks 62 are distributed in a rectangular array, which greatly increases the contact area between water and air and promotes heat exchange. Then, the water flows through the water receiving tank 642 into the heat dissipation component 64. The Z-shaped water holes 643 extend the water flow path, allowing the water to come into contact with the air multiple times in the tortuous flow, further dissipating heat. This effectively solves the problem of low cooling efficiency in traditional cooling towers under high temperature and high humidity conditions. The design of honeycomb perforated blocks 62 and Z-shaped water holes 643 enhances heat exchange, and can quickly cool down even in harsh environments, ensuring the efficient and stable operation of the open-loop cooling equipment and meeting the ever-growing cooling needs of industry and buildings.

[0033] In this embodiment, the water-saving water spraying device 9 includes a circulating pump 91. The left end of the circulating pump 91 is fixedly connected to the lower right end of the bottom pool frame 1 through a water inlet pipe. The output end of the circulating pump 91 is fixedly connected to a suction pipe 92. The end of the suction pipe 92 away from the circulating pump 91 extends into the upper part of the cooling tower shell 4 and is fixedly connected to a large annular pipe 93. The right side of the inner wall of the large annular pipe 93 is fixedly connected to a connecting pipe 94. The end of the connecting pipe 94 away from the large annular pipe 93 is fixedly connected to a small annular pipe 95. Several plastic water spray nozzles 96 are fixedly connected to the lower part of the outer surface of the connecting pipe 94 and the small annular pipe 95. The small annular pipe 95 is located above the inner side of the plastic water spray nozzles 96. Several plastic water spray nozzles 96 are located directly above the plastic filler block 61.

[0034] Through the above scheme: the circulating pump 91 draws water from the bottom pool frame 1, sends it to the large annular pipe 93 through the suction pipe 92, and then distributes it to the small annular pipe 95 through the connecting pipe 94. Finally, the water is evenly sprayed onto the plastic filler block 61 by the plastic spray nozzle 96. The nozzle is precisely positioned so that the water flow is concentrated to cover the heat dissipation area, reducing splash loss. The annular pipe design ensures that the water flow is evenly distributed, avoids excessive local spraying, and effectively improves the water resource utilization efficiency of the open circulating cooling equipment.

[0035] It should be noted that this utility model is an open-type circulating cooling device. During use, firstly, circulating water is stored in the bottom pool frame 1. The device is operated by controlling the operation key 2. The circulating pump 91 in the water-saving water spraying device 9 pumps the water in the bottom pool frame 1 through the suction pipe 92 to the large annular pipe 93, the connecting pipe 94, and the small annular pipe 95. Finally, the water is evenly sprayed onto the plastic filler block 61 of the cooling structure 6 by the plastic spray nozzle 96. The water flows through the drain hole 63 and through the honeycomb hollow block 62 to increase the contact area with the air and carry out preliminary heat exchange. Then, it falls into the water receiving tank of the heat dissipation component 64. 642, and then the Z-shaped water hole 643 further extends the water flow path and enhances heat dissipation. The axial flow fan 7 accelerates the air flow and carries away the heat. The baffle plate 8 prevents water droplets from escaping with the airflow, so that the cooled water flows back to the bottom pool frame 1 to complete the circulation. In addition, the viewing window 5 makes it easy to observe the internal operation. The drain pipe 3 is used for drainage and cleaning. Therefore, the water-saving water spray device 9 reduces water waste. The cooling structure 6 and the axial flow fan 7 work together to improve cooling efficiency, effectively solving the problems of high energy consumption, low efficiency and large waste of traditional equipment. It has the beneficial effects of high efficiency and energy saving, water saving and environmental protection, and easy operation and maintenance.
