Description

Technical Field

[0001] The utility model relates to the technical field of air coolers, in particular to a novel energy-saving and humidifying air cooler. Background Art

[0002] The working principle of traditional air coolers is to use power to drive the impeller to rotate, and the vortex generated continuously draws air in. After the cold air contacts the hot pipe, it transfers heat and cools the hot material in the pipe. However, in a dry and high-temperature environment, the outdoor temperature is high, and there is no device that can affect the air state by adjusting the temperature of the external atmosphere, thereby ensuring the heat exchange performance of the air cooler.

[0003] A patent CN204373456U is disclosed in the prior art. The solution includes a shell, a shell, an axial flow fan is arranged at the upper end of the shell, an air cooler tube bundle is horizontally arranged at a position below the axial flow fan in the shell, an air inlet area is arranged at a position below the air cooler tube bundle in the shell, and a plurality of stainless steel pipes are arranged at peripheral positions near the air inlet area in the shell, and a plurality of nozzles are installed on the stainless steel pipes. When working, desalted water is passed into the stainless steel pipes through a high-pressure water pump, and mist is sprayed out through the nozzles, thereby humidifying the air inlet area environment below the air cooler tube bundle, and reducing the air temperature entering the air cooler tube bundle in the dry and high temperature environment in summer, thereby ensuring the cooling performance of the closed cooling system.

[0004] As the existing devices including the above patents are used, the shortcomings of the technology are gradually exposed, which are mainly manifested in the following aspects:

[0005] First, the cooling tube bundle leaks out, making it easy for the equipment to be damaged by external wind, snow, and hail.

[0006] Second, the outside air flow rate is uneven, the pressure loss is large, and it is easy to be affected by the environment and cause backflow.

[0007] Third, the outside temperature is high in summer, and the air temperature at the air inlet is relatively high. After the gas enters the cooling pipe box, the heat exchange capacity is small and does not meet the cooling requirements.

[0008] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0009] In view of the defects in the prior art, the utility model provides a new energy-saving humidifying air cooler to solve the problems that the cooling tube bundle of the traditional air cooler leaks, which is easy to be damaged by the external wind, snow and hail; the external air flow rate is uneven, the pressure loss is large, and it is easy to be affected by the environment and produce backflow; and the outside temperature is high in summer, the air temperature at the air inlet is relatively high, and the heat exchange capacity of the gas after entering the cooling tube box is small, which does not meet the cooling requirements.

[0010] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0011] A novel energy-saving humidifying air cooler comprises a box body, wherein an air outlet is arranged on the top of the box body, an air inlet is arranged on the side wall of the box body, an atomizing spray device is arranged on the inner side of the air inlet, and a finned tube plate is arranged in the box body corresponding to the air inlet.

[0012] As an optimized solution, the fin tube plate is arranged obliquely, the upper end of the fin tube plate is close to the side wall of the box body, and the lower end of the fin tube plate is close to the bottom surface of the box body.

[0013] As an optimized solution, the atomizing spray device includes a plurality of atomizing nozzles distributed in a matrix.

[0014] As an optimized solution, the atomizing spray device includes a water supply pipeline, which includes an outer tube arranged in a rectangular shape, and a plurality of interconnected vertical tubes are fixedly connected in parallel inside the outer tube, and a plurality of atomizing nozzles are correspondingly connected to the outer tube and the vertical tube.

[0015] As an optimized solution, a water collecting device is provided in the area of ​​the box body between the lower end of the fin tube plate and the inner wall of the box body.

[0016] As an optimized solution, an air inlet shutter is provided in the air inlet.

[0017] As an optimized solution, an axial flow fan is provided in the air outlet.

[0018] As an optimized solution, two air inlets are provided and are located on opposite side walls of the box body, and two atomizing spray devices, water collecting devices and fin tube plates are provided accordingly.

[0019] As an optimized solution, the fin tube sheet is fixed to the inner wall of the box body through a support frame.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] The devices inside the box are symmetrically distributed. The fin tube sheet for heat exchange is arranged at the bottom of the axial flow fan inside the box. The fin tube sheet is placed obliquely. The two ends of the fin tube sheet are connected to the circulating medium pipeline to flow the circulating medium. The lower box of the fin heat exchange tube sheet is provided with an air inlet shutter. An atomizing spray device is arranged between the air inlet shutter and the fin tube sheet. The circulating water can be drawn from the groundwater and connected to the atomizing spray device; the bottom of the fin tube box at the bottom of the box and the bottom of the air inlet shutter are provided with a water collecting device, which can recycle the excess circulating water for secondary use to improve the utilization rate of water resources, or it can be directly discharged into the ground. The whole process is pollution-free.

[0022] The atomizing spray device can be selectively turned on or off according to the temperature. In the cold winter, when only air can meet the heat exchange requirements of the circulating medium, the atomizing spray device can be turned off. At this time, the cold air from the outside enters the box through the air inlet shutters and reaches the fin tube plate position. The cold air and the circulating medium in the fin tube plate undergo non-contact heat exchange and are converted into hot air. The hot air is discharged into the atmosphere through the axial flow fan;

[0023] In the hot summer, when air alone cannot meet the heat exchange requirements of the circulating medium, the atomizing spray device can be turned on. At this time, the outside hot air enters the box through the air inlet shutters, and then reaches the fin tube plate position through the atomizing spray device. When the outside hot air passes through the atomizing spray device, the atomizing nozzle sprays mist-like circulating cooling water to humidify the hot air entering from the outside, so that the dry bulb temperature of the hot air entering from the outside is reduced to close to the wet bulb temperature, thereby cooling the hot air and converting it into cold air. After the outside hot air is converted into cold air, it exchanges heat with the circulating medium in the fin tube plate in a non-contact manner, takes away the heat of the circulating medium in the fin tube plate and converts it into hot air, and the hot air is discharged into the atmosphere through the axial flow fan.

[0024] The box separates the air inlet and outlet, preventing hot air backflow and external environmental factors from causing damage to the equipment;

[0025] The tilted finned tube sheet can increase the heat exchange area and reduce the overall height of the equipment, thus reducing the floor space and saving costs;

[0026] The atomizing spray device only operates in hot weather to cool the outside air. The excess mist circulating water is recovered through the water collecting device, which increases the heat exchange efficiency of the equipment and improves the utilization rate of water resources.

[0033] The fin tube sheet 4 is arranged obliquely, the upper end of the fin tube sheet 4 is close to the side wall of the box body 2 , and the lower end of the fin tube sheet 4 is close to the bottom surface of the box body 2 .

[0034] The atomizing spray device comprises a plurality of atomizing nozzles 6 which are arranged in a matrix distribution.

[0035] The atomizing spray device comprises a water supply pipeline 7, which comprises an outer pipe arranged in a rectangular shape, a plurality of interconnected vertical pipes are fixedly connected in parallel inside the outer pipe, and a plurality of atomizing nozzles 6 are correspondingly connected to the outer pipe and the vertical pipes.

[0036] A water collecting device 8 is provided in the area of ​​the box body 2 between the lower end of the fin tube plate 4 and the inner wall of the box body 2 .

[0037] An air inlet shutter 5 is arranged in the air inlet.

[0038] An axial flow fan 1 is arranged in the air outlet.

[0039] There are two air inlets, which are located on opposite side walls of the box body 2. There are two atomizing spray devices, two water collecting devices 8 and two fin tube plates 4 respectively.

[0040] The fin tube sheet 4 is fixed to the inner wall of the box body 2 through the support frame 3.

[0041] The working principle of this device is:

[0042] The devices inside the box 2 are symmetrically distributed. The fin tube sheet 4 for heat exchange is arranged at the lower part of the axial flow fan 1 inside the box 2. The fin tube sheet 4 is placed obliquely. Both ends of the fin tube sheet 4 are connected to the circulating medium pipeline to flow the circulating medium. An air inlet louver 5 is arranged on the lower part of the box 2 of the fin heat exchange tube sheet. An atomizing spray device is arranged between the air inlet louver 5 and the fin tube sheet 4. The circulating water can be drawn from the groundwater and connected to the atomizing spray device; a water collecting device 8 is arranged at the bottom of the fin tube box at the bottom of the box 2 and the bottom of the air inlet louver 5, which can recycle the excess circulating water for secondary use to improve the utilization rate of water resources, or it can be directly discharged into the ground. The whole process is pollution-free.

[0043] The atomizing spray device can be selectively turned on or off according to the temperature. In the cold winter, when only air can meet the heat exchange requirements of the circulating medium, the atomizing spray device can be turned off. At this time, the cold air from the outside enters the box body 2 through the air inlet shutter 5 and reaches the position of the fin tube plate 4. The cold air and the circulating medium in the fin tube plate 4 are converted into hot air through non-contact heat exchange. The hot air is discharged into the atmosphere through the axial flow fan 1;

[0044] In the hot summer, when air alone cannot meet the heat exchange requirements of the circulating medium, the atomizing spray device can be turned on. At this time, the external hot air enters the box body 2 through the air inlet shutters, and then reaches the fin tube plate 4 through the atomizing spray device. When the external hot air passes through the atomizing spray device, the atomizing nozzle 6 sprays mist-like circulating cooling water to humidify the hot air entering from the outside, so that the dry bulb temperature of the hot air entering from the outside is reduced to close to the wet bulb temperature, thereby cooling the hot air and converting it into cold air. After the external hot air is converted into cold air, it exchanges heat with the circulating medium in the fin tube plate 4 in a non-contact manner, takes away the heat of the circulating medium in the fin tube plate 4 and converts it into hot air, and the hot air is discharged into the atmosphere through the axial flow fan 1.

[0045] The air inlet and the air outlet are separated by the box 2, which prevents the equipment from being damaged by hot air backflow and external environmental factors;

[0046] The tilted fin tube sheet 4 can increase the heat exchange area and reduce the overall height of the equipment, thereby reducing the floor space and saving costs;

[0047] The atomizing spray device is only operated during hot weather to cool the outside air, and the excess mist circulating water is recovered through the water collecting device 8, which increases the heat exchange efficiency of the equipment and improves the utilization rate of water resources.
