Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, and more specifically, to a closed cooling filling tower for changing wind resistance flow. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant, absorbing heat from the system and discharging it into the atmosphere to lower the water temperature. Its cooling principle is to use the heat exchange between water and air flow to generate steam, and the steam evaporates and takes away the heat to achieve evaporative heat dissipation, convection heat transfer, and radiation heat transfer. It dissipates the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature through an evaporative heat dissipation device to ensure the normal operation of the system.

[0003] A closed cooling tower passes hot water through heat exchange tubes, and the heat is transferred to the spray water and air through the heat exchange tubes. The fan rotates to provide flowing air for the cooling tower. The outside air enters the cooling tower through the air inlet. Since the air inlets are opened on both sides of the heat exchange tower, the air enters the tower from both sides and moves upward, which increases the resistance to air movement. At the same time, when the air passes through the circular heat exchange tubes, turbulence will be generated on the back side of the heat exchange tubes, affecting the flow of air. The right angles in the tower also increase the resistance to air flow.

[0004] In view of this, research and improvement are conducted on the existing problems, and a closed cooling packed tower with changed wind resistance flow is provided, aiming to achieve the purpose of solving the problem and improving the practical value through this technology.

[0006] In order to achieve the above object, the utility model provides a closed cooling packing tower for changing wind resistance flow, which is achieved by the following specific technical means:

[0007] A closed cooling packing tower for changing air resistance flow, comprising: a main body, a fan, an air inlet, a first deflector, heat exchange tubes, a partition plate, a water inlet pipe, a water outlet pipe, packing, a second deflector, a water delivery pipe, a sprinkler head, and a water pump; the main body is of a rectangular shell structure, and the fan is installed on the top surface of the main body; the air inlets are opened on both sides of the lower part of the main body; the first deflector is arranged inside the air inlets, and both ends of the first deflector are fixedly connected to the inner wall of the main body; the heat exchange tubes are fixedly installed above the first deflector, and the partition plate is welded and fixed to the outer wall of the heat exchange tubes in parallel with the heat exchange tubes; the water inlet pipe and the water outlet pipe are respectively connected to both ends of the heat exchange tubes; the packing is arranged above the heat exchange tubes; the second deflector is fixed at the four corners inside the upper end of the main body; the upper end of the water delivery pipe is arranged above the packing, the lower end of the water delivery pipe is connected to the lower part of the main body, and the water pump is installed at the lower end of the water delivery pipe; the sprinkler heads are evenly arranged on the outer wall of the upper end of the water delivery pipe.

[0008] As a further optimization of this technical solution, in the closed cooling packing tower for changing air resistance flow of the present utility model, the first deflector is in the shape of a Chinese character "ren" (human)-shaped plate structure.

[0009] As a further optimization of this technical solution, in the closed cooling packing tower for changing air resistance flow of the present utility model, the partition plate is a rectangular plate structure made of metal.

[0010] As a further optimization of this technical solution, in the closed cooling packing tower for changing air resistance flow of the present utility model, the second deflector is in the shape of an arc-shaped plate structure, and there are four second deflectors arranged at the top of the main body.

[0011] Due to the application of the above technical solution, the present utility model has the following advantages compared with the prior art:

[0012] 1. In the present utility model, the first deflector is arranged inside the air inlets. The first deflector is in the shape of a Chinese character "ren" (human)-shaped plate structure, and the second deflector is in the shape of an arc-shaped plate structure, and there are four second deflectors arranged at the top of the main body. Air enters the main body from the air inlets and is deflected upward by the first deflector to cool the heat exchange tubes and the packing. After being deflected by the second deflector, it is sucked out by the fan. The first deflector and the second deflector play a role in deflecting the air, reducing the generation of turbulence, reducing the resistance of air flow, and improving the heat dissipation effect of the packing tower.

[0013] 2. In the present utility model, the partition plate is a rectangular plate structure made of metal. The partition plate is welded and fixed to the outer wall of the heat exchange tubes in parallel with the heat exchange tubes. When air flows through the heat exchange tubes, due to the blocking of the partition plate, the air flows through both sides of the partition plate, reducing the turbulence generated when the air passes through the heat exchange tubes. At the same time, the partition plate increases the heat dissipation area of the heat exchange tubes and improves the heat dissipation effect of the heat exchange tubes.

The utility model improves the closed cooling packing tower that changes the wind resistance flow, has the advantages of guiding the air by setting the guide plate, reducing turbulence and wind resistance by setting the partition, and having good heat dissipation effect, thereby effectively solving the problems and shortcomings in the existing technology and equipment.

[0024] Specific implementation steps:

[0025] During use, hot water enters the heat exchange tubes 5 through the water inlet pipe 7, the water pump 13 sends the water into the water delivery pipe 11, and the water is sprayed out through the spray heads 12. The water falls on the surfaces of the packing 9 and the heat exchange tubes 5. The fan 2 is turned on, and air enters the main body 1 from the air inlet 3, moves upward through the diversion of the first guide plate 4, takes away the humid hot air, cools the heat exchange tubes 5, and at the same time cools the packing 9. After being guided by the second guide plate 10, the air is discharged by the fan 2, and the heat is dissipated into the air. The cooled water in the heat exchange tubes 5 is discharged from the water outlet pipe 8.

[0026] In summary, for the closed cooling packing tower that changes the air resistance flow, the first deflector is arranged inside the air inlet. The first deflector is in the shape of a Chinese character "ren" plate structure, and the second deflector is in an arc plate structure. And the second deflector is arranged at four places on the top of the main body. Air enters the main body from the air inlet and is deflected upward by the first deflector to cool the heat exchange tubes and the packing.

The partition is a rectangular plate structure made of metal. The partition is welded and fixed to the outer wall of the heat exchange tubes parallel to the heat exchange tubes. When air flows through the heat exchange tubes, due to the blockage of the partition, the air flows through both sides of the partition, reducing the turbulence generated when air passes through the heat exchange tubes. At the same time, the partition increases the heat dissipation area of the heat exchange tubes and improves the heat dissipation effect of the heat exchange tubes. Through the improvement of the closed cooling packing tower that changes the air resistance flow, the utility model has the advantages of deflecting the air by setting deflectors, reducing turbulence by setting partitions, reducing air resistance, and having good heat dissipation effect, thus effectively solving the problems and deficiencies in the prior art and equipment.
