Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically to a cooling tower with antifreeze function. 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. In winter, when ambient temperatures are low and the system experiences intermittent periods of no or low heat load, the heat exchangers in the cooling tower are at risk of freezing. The conventional method has been to drain water from individual sectors; however, frequent filling and draining of sectors is detrimental to the safe operation of the cooling tower and is uneconomical.

[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] To address the shortcomings of existing technologies, this utility model provides a cooling tower with antifreeze function, which can improve the heat preservation effect of the cooling tower in low-temperature winter environments, prevent heat exchangers from freezing and ensure safer operation of the cooling tower.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A cooling tower with antifreeze function includes a tower frame, a heat exchanger, and a sealing mechanism. The side walls of the tower frame are provided with heat-insulating walls. The two opposite sides of the tower frame are provided with air inlets, and the upper end of the tower frame is provided with an air outlet. The sealing mechanism is located at the lower end of the air outlet. The sealing mechanism includes guide rails, sliding rods, insulation blankets, guide wheels, and pull ropes. The guide rails are symmetrically connected to the tower frame. The two ends of the sliding rods are slidably connected to the guide rails. One end of the insulation blanket is fixedly connected to the guide rails, and the other end is fixedly connected to the sliding rods. The front and rear ends of the guide rails are provided with rotating shafts, and the guide wheels are rotatably connected to the rotating shafts. The sliding rods are provided with two pull ropes, which are respectively wound around the two guide wheels at the front and rear ends.

[0006] Furthermore, the air inlet is equipped with an air volume adjustment device.

[0007] Furthermore, the air intake adjustment device is an insulated electric roller shutter door.

[0008] Furthermore, the tower has load-bearing beams inside, ventilation openings are provided between the load-bearing beams, and a tripod is provided on the load-bearing structure.

[0009] Furthermore, the tripod includes a base plate and two inclined plates disposed on the base plate, the upper ends of the inclined plates being connected together, and the heat exchanger being fixedly mounted on the inclined plates.

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

[0011] This invention provides a cooling tower with antifreeze function. It offers the following advantages: In low-temperature winter environments with intermittent no or low heat load, the airflow regulating device reduces the airflow or even closes the air inlet, and then a sealing mechanism seals the air outlet. By using double sealing measures to close both the air inlet and outlet, the tower's interior achieves a relatively sealed state. Furthermore, the tower's side walls are equipped with insulation panels, further improving the internal insulation performance. This effectively reduces heat exchange between the heat exchanger and the atmosphere, allowing the heat exchanger to operate safely even without water leakage, thus reducing the risk of freezing damage.

Detailed Implementation

[0019] 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.

[0020] Please see the appendix Figure 1 - Appendix Figure 4This utility model provides a cooling tower with antifreeze function, including a tower frame 1, a heat exchanger 2, and a sealing mechanism 3. Each of the four side walls of the tower frame 1 is provided with an insulated wall 11, which can be made of conventional insulation materials. Air inlets 12 are provided on two opposite sides of the tower frame 1, and an air outlet 13 is provided at the top of the tower frame 1. An air duct 14 is provided above the air outlet 13, and a fan 15 is installed inside the air duct 14. The fan 15 can accelerate the airflow within the tower frame 1, further improving heat exchange efficiency. The sealing mechanism 3 is located at the lower end of the air outlet 13. The sealing mechanism 3 includes a guide rail 31, a sliding rod 32, an insulation blanket 33, guide wheels 34, and pull ropes 35. The guide rail 31 is symmetrically connected to the tower 1. The two ends of the sliding rod 32 are slidably connected to the guide rail 31. One end of the insulation blanket 33 is fixedly connected to the guide rail 31, and the other end is fixedly connected to the sliding rod 32. The front and rear ends of the guide rail 31 are provided with rotating shafts 36, and the guide wheels 34 are rotatably connected to the rotating shafts 36. The sliding rod 32 is provided with two pull ropes 35, which are respectively wound around the two guide wheels 34 at the front and rear ends. With the above structure, in the case of low temperature in winter and intermittent no heat load or low heat load of the system, the sliding rod 32 can be dragged by manually pulling the pull ropes 35, so that the insulation blanket 33 completely blocks the air outlet 13. In summer when the temperature is high, the pull rope 35 can be manually pulled to drag the slide bar 32 to move the insulation blanket 33 to one side and stack it up, thereby fully opening the air outlet 13.

[0021] In this embodiment, an air intake regulating device 4 is provided on the air inlet 12, which is an insulated electric roller shutter door. The insulated electric roller shutter door is a conventional existing technology. By controlling the insulated electric roller shutter door, the opening area of ​​the air inlet 12 can be controlled, thereby adjusting the air intake volume of the air inlet 12. In winter when the temperature is low and the system has intermittent no heat load or low heat load, the insulated electric roller shutter door can completely close the air inlet 12.

[0022] In this embodiment, the tower 1 has a supporting beam 16 inside, and vents 17 are provided between the supporting beams 16. The vents 17 allow external air to flow upward and contact the heat exchanger 2. A tripod 5 is provided on the supporting structure. The tripod 5 includes a base plate 51 and two brackets mounted on the base plate 51. The upper ends of the inclined plates 52 are connected together, and the heat exchanger 2 is fixedly installed on the inclined plates 52. With the above structure, the heat exchanger 2 is more firmly installed, which can effectively increase the number of heat exchangers 2 installed, improve the heat exchange effect, and facilitate the disassembly, assembly, and maintenance of the heat exchanger 2.

[0023] The working principle of this invention is as follows: Hot water enters the heat exchanger through the inlet, is cooled and dissipates heat inside the heat exchanger, and then flows back out through the outlet. In winter, when the temperature is low and the system experiences intermittent periods of no or low heat load, the sliding rod 32 can be moved by manually pulling the rope 35, completely sealing the air outlet 13 with the insulation blanket 33. Furthermore, the insulated electric roller shutter can be opened to completely seal the air inlet 12, thus achieving a sealed and insulated interior for the cooling tower.

[0024] Compared with existing technologies, the advantages of this new technology are that, in low-temperature winter environments with intermittent no or low heat loads on the system, the air intake regulating device 4 reduces the air intake or even closes the air intake 12, and then the sealing mechanism 3 seals the air outlet 13. By sealing both the air intake 12 and the air outlet 13 with double sealing measures, a relatively sealed state is achieved inside the tower 1. Furthermore, the side walls of the tower 1 are equipped with insulation panels, further improving the insulation performance inside the tower 1. This effectively reduces heat exchange between the heat exchanger 2 and the atmosphere, allowing the heat exchanger 2 to operate safely even without water leakage, reducing the risk of freezing damage.

[0025] 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.
