Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically to an energy-saving, heat-insulating, and anti-freezing cooling tower. Background Technology

[0002] Cooling towers are a crucial component of cold-end systems in industrial production, primarily used for heat dissipation and cooling. The outlet water temperature is closely related to the surrounding environmental conditions and the heat load of the thermal system. Traditional cooling towers, to prevent freezing in low-temperature winter environments, typically employ a conventional indirect drainage method. When the risk of freezing damage is anticipated, operators manually or through simple logic control drain all or part of the circulating water from a specific sector or the entire tower into an underground storage tank. When needed, the water pump is restarted to pump the water back into the system. This method consumes a significant amount of electricity for frequent starting and stopping of high-power pumps for filling and draining, significantly increasing energy costs. Furthermore, the drained water is treated softened water, resulting in substantial waste of water resources and chemical agents, making it highly uneconomical and energy-inefficient. In addition, after drainage, the tower's packing and other components are exposed to humid air, accelerating corrosion and shortening equipment lifespan.

[0003] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to this case. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, this utility model provides an energy-saving heat preservation and antifreeze cooling tower, which has a high-efficiency antifreeze and heat preservation effect and can effectively save energy consumption.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An energy-saving, heat-insulating, and anti-freezing cooling tower includes a tower frame, a heat exchanger, and a covering mechanism. The side walls of the tower frame are equipped with heat-insulating wall panels. The covering mechanism includes a tripod, an insulation blanket, support plates, fixed pulleys, cables, and a handwheel. The tripod is connected inside the tower frame, and the heat exchanger is installed on the side of the tripod. The support plates are connected to the upper end of the tripod, and two support plates are respectively connected to the front and rear ends of the tripod. Each support plate has two rotatably connected fixed pulleys at its upper end. The handwheel is rotatably connected to the lower end of the tripod. The insulation blanket is placed on the heat exchanger, and the two upper corners of the insulation blanket are tied to one end of the cable. The other end of the cable passes around the fixed pulleys and is connected to the handwheel.

[0006] Furthermore, the tower is equipped with mounting brackets inside, and ventilation openings are provided between the mounting brackets. The tripod is connected to the mounting brackets.

[0007] Furthermore, the tripod includes a base plate, an inclined plate, and side plates. The inclined plate is connected to the base plate, and the two inclined plates are symmetrically arranged on the left and right. The upper ends of the inclined plates are connected together. The heat exchanger is connected to the inclined plate. The two side plates are installed at the front and rear ends of the base plate, and the handwheel is rotatably connected to the side plates.

[0008] Furthermore, air inlets are provided on the two corresponding sides of the tower, and air volume adjustment devices are provided on the air inlets.

[0009] Furthermore, the air volume regulating device is an insulated electric roller shutter door.

[0010] Furthermore, an air outlet is provided at the upper end of the tower, and an air duct is provided at the upper end of the air outlet, with a fan installed inside the air duct.

[0011] This utility model provides an energy-saving, heat-insulating, and anti-freezing cooling tower. It offers the following advantages: In winter, when the ambient temperature is low and the system experiences intermittent periods of no or low heat load, this new design uses an insulated electric roller shutter door to seal the air inlet. Then, an insulation blanket is placed over the heat exchanger via a covering mechanism, providing insulation and simultaneously sealing the ventilation openings. This creates a relatively sealed space for the heat exchanger inside the tower, further enhanced by insulation walls. This reduces heat exchange between the heat exchanger and the atmosphere, allowing the heat exchanger to operate safely even without water leakage, reducing the risk of freezing damage, significantly saving energy costs associated with water leakage, and making it more energy-efficient and environmentally friendly.

Detailed Implementation

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Please see the appendix Figure 1 - Appendix Figure 5 This utility model provides an energy-saving, heat-insulating, and anti-freezing cooling tower, including a tower frame 1, a heat exchanger 2, and a covering mechanism 3. The side walls of the tower frame 1 are provided with heat-insulating wall panels 6. The covering mechanism 3 includes a triangular frame, a heat-insulating blanket 32, a support plate 33, a fixed pulley 34, a cable 35, and a handwheel 36. The tower frame 1 has an installation frame 11 inside, with ventilation openings 12 between the installation frames 11. The triangular frame is connected to the installation frame 11 and includes a base plate 311, an inclined plate 312, and side plates 313. The inclined plate 312 is connected to the base plate 311, and the two inclined plates 312 are symmetrically arranged on the left and right sides. The upper ends of the inclined plates 312 are connected together. The heat exchanger 2 is connected to the inclined plate 312. The two side plates are installed at the front and rear ends of the base plate 311. Support plates 33 are connected to the upper end of the tripod, and two support plates 33 are respectively connected to the front and rear ends of the tripod. Each support plate 33 has two rotatably connected fixed pulleys 34 at its upper end, and a handwheel 36 is rotatably connected to the side plate 313. An insulation blanket 32 ​​is placed over the heat exchanger 2. The two upper corners of the insulation blanket 32 ​​are tied to one end of a cable 35, and the other end of the cable 35 passes around the fixed pulleys 34 and connects to the handwheel 36. By rotating the handwheels 36 at both ends, the insulation blanket 32 ​​can be lifted by the cable 35, allowing it to naturally adhere to one side of the heat exchanger 2 under gravity, thus sealing the vent 12. In summer, the insulation blanket 32 ​​can be removed and stacked aside, saving space and reducing the workload and intensity of the operators. The aforementioned handwheel 36 is existing technology. After the insulation blanket 32 ​​is lifted and fixed, it has an anti-rotation effect, ensuring that the insulation blanket 32 ​​can stably cover the heat exchanger 2. Its specific structure will not be described in detail here.

[0020] In this embodiment, air inlets 13 are provided on two corresponding sides of the tower 1, and air volume regulating devices 4 are provided on the air inlets 13. More specifically, the air volume regulating device 4 is an insulated electric roller shutter door. The insulated electric roller shutter door can seal the air inlets 13, so that a relatively sealed space is formed inside the tower 1, preventing the heat exchanger 2 from contacting the outside atmosphere and preventing the heat exchanger 2 from freezing.

[0021] In this embodiment, an air outlet 14 is provided at the upper end of the tower 1, and an air duct 5 is provided at the upper end of the air outlet 14. A fan 51 is provided inside the air duct 5. The fan 51 can accelerate the gas flow speed inside the tower 1, thereby improving the heat dissipation efficiency.

[0022] The working principle of this invention is as follows: In winter, when the ambient temperature is low and the system experiences intermittent periods of no or low heat load, an insulated electric roller shutter door is used to seal the air inlet 13. By rotating the handwheels 36 at both ends, the insulation blanket 32 ​​is lifted by the cable 35, allowing it to naturally adhere to one side of the heat exchanger 2 under gravity, thus insulating the heat exchanger 2 and simultaneously sealing the vent 12. In summer, the insulation blanket 32 ​​can be removed and stacked aside. Compared with existing technologies, the advantages of this new technology are that, in winter when the ambient temperature is low and the system has intermittent no or low heat load, the air inlet 13 is sealed by an insulated electric roller shutter door, and then the heat exchanger 2 is covered by an insulation blanket 32 ​​through the covering mechanism 3, which achieves a certain heat preservation effect. In addition, the heat exchanger 2 inside the tower 1 can be sealed during the covering process of the insulation blanket 32, so that the heat exchanger 2 can be in a relatively sealed space. The heat exchanger 2 is also insulated by the insulation wall panel 6, thereby reducing the heat exchange between the heat exchanger 2 and the atmosphere. This allows the heat exchanger 2 to operate safely even without water leakage, reducing the risk of freezing damage and greatly saving the energy cost required for water leakage. It is also more energy-efficient and environmentally friendly.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
