Description

Technical Field

[0001] This utility model relates to the field of central air conditioning cooling tower technology, specifically to a central air conditioning cooling device. Background Technology

[0002] Central air conditioning cooling water is an important component of a central air conditioning system. Its circulation process involves the chilled water circulation system exchanging heat with the indoor environment, which inevitably removes a large amount of heat energy from the room. This heat energy is transferred to the cooling water through the refrigerant in the main unit, causing the cooling water temperature to rise. The cooling pump then pressurizes the heated cooling water into the cooling tower, where it exchanges heat with the atmosphere, lowers the temperature, and is then sent back to the main unit condenser. This cycle continues continuously, thereby dissipating indoor heat to the outside.

[0003] Currently, when central air conditioning cooling units cool circulating water, the central air conditioning cooling towers are generally installed on the roof of buildings and exposed to the external environment. In hot weather, especially in summer, prolonged exposure to sunlight can cause the surface and internal temperature of the central air conditioning cooling tower to rise. This reduces the cooling effect of the central air conditioning cooling tower on the circulating water, which in turn affects the cooling efficiency of the central air conditioning system. Utility Model Content

[0004] The purpose of this invention is to provide a central air conditioning cooling device to address the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a central air conditioning cooling device, comprising:

[0006] The cooling tower body has an air inlet frame fixedly connected to its bottom end, a water collection frame fixedly connected to its bottom end, and two packing layers fixedly provided on the two inner side walls of the cooling tower body.

[0007] A first heat dissipation side frame is disposed on one side of the cooling tower body, and a second heat dissipation side frame is fixedly disposed on the other side of the cooling tower body. Heat dissipation fin groups are fixedly disposed on both sides of the cooling tower body. The inner sides of the two heat dissipation fin groups pass through the two sides of the cooling tower body and are in close contact with the two packing layers. The outer sides of the two heat dissipation fin groups are respectively disposed inside the first heat dissipation side frame and the second heat dissipation side frame. A blowing assembly is disposed on the first heat dissipation side frame and the second heat dissipation side frame.

[0008] Preferably, the air blowing assembly includes a cooling fan group fixedly embedded at the front end of the first heat dissipation side frame. The air inlet and outlet ends of the cooling fan group are respectively located outside and inside the first heat dissipation side frame. Multiple connecting air ducts are fixedly provided between the rear ends of the first heat dissipation side frame and the second heat dissipation side frame. The interiors of the first heat dissipation side frame and the second heat dissipation side frame are interconnected through multiple connecting air ducts. Multiple air outlet holes are opened at the front of the outer side of the second heat dissipation side frame to facilitate the removal of heat from the two heat dissipation fin groups.

[0009] Preferably, the outer end of the air inlet frame is provided with multiple air inlets, and a dustproof grid plate is fixed on the inner wall of the air inlet to facilitate the entry of external air into the air inlet frame and the interior of the cooling tower.

[0010] Preferably, the cooling tower body has a water inlet pipe at the top front end, one end of which passes through the front end of the cooling tower body and extends into the interior of the cooling tower body. A connecting water pipe is fixedly provided at one end of the water inlet pipe, and a water distribution pipe is fixedly provided at both ends of the connecting water pipe. The two water distribution pipes are respectively provided at the top of the two packing layers, and multiple water distribution nozzles are fixedly provided at the bottom end of the water distribution pipes to facilitate the spraying of high-temperature circulating water onto the two packing layers.

[0011] Preferably, a water outlet pipe is fixedly provided at the bottom front end of the water collection frame, and one end of the water outlet pipe passes through the front end of the water collection frame and is connected to the inside of the water collection frame to facilitate the return of the cooled circulating water.

[0012] Preferably, a cooling fan is fixedly embedded at the top of the cooling tower body, and the air inlet of the cooling fan extends into the interior of the cooling tower body to facilitate air cooling of the circulating water.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] The cooling tower uses two heat dissipation fins to conduct heat from its surface and interior, and then uses a cooling fan to carry away the heat from the two heat dissipation fins. This prevents the surface and interior of the cooling tower from rapidly increasing in temperature due to sunlight exposure, effectively ensuring the cooling effect of the cooling device on the circulating water, and thus ensuring the cooling effect of the central air conditioning.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figures 1 to 5 A central air conditioning cooling device is shown, comprising:

[0025] The cooling tower body 1 has a cooling fan 18 fixedly embedded at the top of the cooling tower body 1. The air inlet of the cooling fan 18 extends into the interior of the cooling tower body 1. An air inlet frame 2 is fixedly connected to the bottom of the cooling tower body 1. Multiple air inlets 11 are opened at the outer end of the air inlet frame 2. A dustproof grid plate 12 is fixedly installed on the inner wall of the air inlet 11. A water collection frame 3 is fixedly connected to the bottom of the air inlet frame 2. Two packing layers 4 are fixedly installed on the two inner side walls of the cooling tower body 1.

[0026] The first heat dissipation side frame 5 is disposed on one side of the cooling tower body 1, and the second heat dissipation side frame 6 is fixedly disposed on the other side of the cooling tower body 1. Heat dissipation fin groups 7 are fixedly disposed on both sides of the cooling tower body 1. The inner sides of the two heat dissipation fin groups 7 pass through the two sides of the cooling tower body 1 and are in close contact with the two packing layers 4. The outer sides of the two heat dissipation fin groups 7 are respectively disposed inside the first heat dissipation side frame 5 and the second heat dissipation side frame 6. Air blowing components are provided on the first heat dissipation side frame 5 and the second heat dissipation side frame 6.

[0027] The air blowing assembly includes a cooling fan group 8 fixedly embedded in the front end of the first heat dissipation side frame 5. The air inlet and outlet ends of the cooling fan group 8 are respectively located outside and inside the first heat dissipation side frame 5. Multiple connecting air ducts 9 are fixedly provided between the rear ends of the first heat dissipation side frame 5 and the second heat dissipation side frame 6. The interiors of the first heat dissipation side frame 5 and the second heat dissipation side frame 6 are interconnected through multiple connecting air ducts 9. Multiple air outlet holes 10 are opened on the front of the outer side of the second heat dissipation side frame 6.

[0028] A water inlet pipe 13 is provided at the top front end of the cooling tower body 1. One end of the water inlet pipe 13 passes through the front end of the cooling tower body 1 and extends into the interior of the cooling tower body 1. A connecting water pipe 14 is fixedly provided at one end of the water inlet pipe 13. A water distribution pipe 15 is fixedly provided at both ends of the connecting water pipe 14. The two water distribution pipes 15 are respectively provided at the top of the two packing layers 4. Multiple water distribution nozzles 16 are fixedly provided at the bottom end of the water distribution pipes 15. A water outlet pipe 17 is fixedly provided at the bottom front end of the water collection frame 3. One end of the water outlet pipe 17 passes through the front end of the water collection frame 3 and is connected to the interior of the water collection frame 3.

[0029] High-temperature circulating water enters the connecting water pipe 14 through the inlet pipe 13, then enters the two distribution pipes 15, and is sprayed onto the two packing layers 4 through multiple distribution nozzles 16. The water flows downwards along the two packing layers 4, activating the cooling fan assembly 8. External air enters the air inlet frame 2 and the cooling tower body 1 through four air inlets 11, then flows upwards inside the cooling tower body 1, finally exiting from the top of the cooling tower body 1. The air flows in the opposite direction to the water flow, and the upward-flowing air carries away the heat from the water. The cooled water then collects in the water collection frame 3 and is discharged from the water collection frame 3 through the outlet pipe 17. During the cooling process, the heat inside and outside the cooling tower 1 is quickly conducted to the two heat dissipation fin groups 7. When the cooling fan group 8 is started, the outside air will enter the first heat dissipation side frame 5 under the drive of the cooling fan group 8, and then enter the second heat dissipation side frame 6 through multiple connecting air pipes 9. Finally, it will be discharged through multiple air outlets 10. When the air passes through the first heat dissipation side frame 5 and the second heat dissipation side frame 6, the air will carry away the heat on the heat dissipation fin groups 7 inside the first heat dissipation side frame 5 and the second heat dissipation side frame 6. In this way, the temperature of the surface and inside of the cooling tower 1 can be reduced, thereby ensuring the cooling effect of the circulating water inside the cooling tower 1.

[0030] This invention uses two heat dissipation fin groups 7 to conduct heat away from the surface and interior of the cooling tower body 1, and then uses a cooling fan group 8 to carry away the heat from the two heat dissipation fin groups 7. This can prevent the surface and interior of the cooling tower body 1 from rapidly increasing in temperature due to sunlight exposure, effectively ensuring the cooling effect of the cooling device on the circulating water, and thus ensuring the cooling effect of the central air conditioning. This embodiment specifically solves the problem in the prior art where, when the central air conditioning cooling device cools the circulating water, since the central air conditioning cooling tower is generally installed on the flat floor of the building roof and exposed to the external environment, the surface and interior temperature of the central air conditioning cooling tower will increase after prolonged exposure to sunlight in hot weather, especially in summer. This will reduce the heat dissipation and cooling effect of the central air conditioning cooling tower on the circulating water, thus affecting the cooling effect of the central air conditioning.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
