In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0039] The present invention discloses an air cooler cooling device, see Figure 1 and Figure 2 , including a box body 1, a spray assembly 2 and a water mist recovery mechanism 3. The box body 1 is a hollow structure with two openings at both ends, one end is set as an air inlet 11, and the other end is set as, and the air outlet 12 is used to communicate with the input end of the air cooler. The cross section of the box body 1 is a rectangular structure, which can be circular or other shapes in actual embodiments. In this application, the length direction of the box body 1 is along the direction from the air inlet 11 to the air outlet 12, and the width direction of the box body 1 is perpendicular to the length direction of the box body 1.

[0040] See also Figure 2 and Figure 3 The spray assembly 2 includes an atomizing nozzle 21 and a water supply assembly 22. The atomizing nozzle 21 is arranged in the box body 1 for spraying the cooling liquid; the water supply assembly 22 is connected to the atomizing nozzle 21 for supplying water to the atomizing nozzle 21. The atomizing nozzle 21 can spray water in an atomized state, increase the contact area between the air and the water mist, and improve the cooling effect.

[0041] See also Figure 2 and Figure 3In order to further improve the cooling effect, an annular water pipe 23 is fixedly arranged in the box body 1, and the atomizing nozzle 21 is arranged on the annular water pipe 23. The atomizing nozzle 21 is connected to the annular water pipe 23. The atomizing nozzle 21 is arranged in two groups, upper and lower. The atomizing nozzle 21 located in the upper group is arranged downwardly, so that the direction of the water flow sprayed from the nozzle is toward the end close to the air inlet 11; the atomizing nozzle 21 located in the lower group is arranged upwardly, so that the water flow there is sprayed upwardly toward the end away from the air inlet 11. Such an arrangement increases the empty time of the water mist in the box body 1, delays the water mist from falling to the bottom of the box body 1, increases the contact area with the air, and thus increases the cooling effect.

[0042] Optional, see Figure 2 and Figure 3 The water delivery assembly 22 includes a water pump 221 and a water delivery pipe 222. One end of the water delivery pipe 222 is connected to the output end of the water pump 221, and the other end is connected to the annular water pipe 23. A water storage tank 13 is arranged outside the box body 1, and the input end of the water pump 221 is connected to the water storage tank 13. The water storage tank 13 contains a coolant, which can also be tap water or other cooling oil. The water storage tank 13 can be arranged on both sides of the box body 1. In this embodiment, the water storage tank 13 is arranged at the bottom of the box body 1.

[0043] When working, the water pump 221 pumps the cooling water in the water tank 13 into the annular water pipe 23 through the water pipe 222, and then sprays it out through the upper and lower groups of atomizing nozzles 21 on the annular water, forming two inclined and relatively parallel groups of water mist walls. After the outside air enters the box body 1 from the air inlet 11 of the box body 1, it passes through the two groups of inclined water mist walls, and the air is fully in contact with the water mist. Because the temperature of the water mist is lower than the temperature of the air, it has the effect of reducing the air temperature. In addition, the inclined water mist increases the contact area with the air, and after the water is sprayed from the atomizing nozzle 21, it diverges freely under the action of gravity, so that the cavity between the two water mist walls is also filled with water mist, further increasing the contact area and time with the air, improving the cooling effect, and thus improving the heat exchange effect of the air cooler under high temperature working conditions; and the structure is simple and the maintenance cost is low.

[0044] See also Figure 2 and Figure 4The water mist recovery mechanism 3 includes an adsorbent 31, a first guide rod 32 and a water collecting tank 33; the water collecting tank 33 is located below the first guide rod 32, and the bottom end of the first guide rod 32 extends into the water collecting tank 33. The water collecting tank 33 is connected to the water storage tank 13. Specifically, an overflow plate 331 is arranged between the water collecting tank 33 and the water storage tank 13. The height of the overflow plate 331 is lower than the height of the water collecting tank 33 and the overflow tank. The cooling water collected in the water collecting tank 33 overflows into the water storage tank 13 after precipitation. In order to further improve the cleanliness of the cooling water in the water storage tank 13, a filter screen 332 is arranged on the overflow plate 331. The filter screen 332 can be a mesh plate or a mesh structure woven by metal wire to further filter the cooling water. A water outlet begins at the bottom of the box body 1, and the water outlet is connected to the water collecting tank 33, so that the cooling water in the box body 1 can be gathered in the water collecting tank 33.

[0045] Among them, see Figure 2 and Figure 4 The first guide rod 32 is vertically fixed in the box body 1, and a plurality of adsorbents 31 are provided. The plurality of adsorbents 31 are arranged at intervals on the first guide rod 32. The adsorbents 31 are used to block and adsorb water mist in the air and flow downward along the first guide rod 32. Specifically, the adsorbent 31 is a fin, the width of the fin is greater than the width of the first guide rod 32, and the fin is arranged on the first guide rod 32 at an angle downward. In the present application, the surface of the fin and the first guide rod 32 is polished or provided with a smooth film on the surface to facilitate the flow of water droplets. The smooth film can be polytetrafluoroethylene. The fin is arranged on the side of the first guide rod 32 close to the air inlet 11 of the box body 1, and the end of the fin away from the first guide rod 32 is higher than the end close to the first guide rod 32. Because the water mist flows from the side close to the air inlet 11 to the air outlet 12, the fins are arranged on the side of the first guide rod 32 close to the air inlet 11, so that the fins can block the water mist, and the fins are arranged at an angle to increase the contact area between the fins and the water mist, so that the water mist condenses on the fins to form water droplets, and flows downward along the first guide rod 32, and then gathers in the collecting trough, thereby achieving the purpose of recycling cooling water.

[0046] In order to further improve the water mist adsorption effect, at least two first guide rods 32 are arranged at intervals along the width direction of the box body 1, and at least two groups of first guide rods 32 are arranged along the length direction of the box body 1. The first guide rods 32 along the length direction of the box body 1 are staggered to facilitate air flow and allow the air to fully contact the fins.

[0047] See also Figure 2 and Figure 5The cooling device further includes an auxiliary water absorption component 4, which is disposed between the water mist recovery mechanism 3 and the air outlet 12. The auxiliary water absorption component 4 includes an adsorption hair 41 and a second guide rod 42, the second guide rod 42 is vertically disposed in the box body 1, one end of the adsorption hair 41 is fixedly disposed on the second guide rod 42, and the other end extends in a direction away from the second guide rod 42, the surface of the second guide rod 42 is set as a smooth surface, the adsorption hair 41 is made of a polymer hygroscopic material or plastic, and the adsorption hair 41 is a cylindrical structure with a smaller diameter, and the diameter of the adsorption hair 41 is less than 0.5 mm.

[0048] Optionally, in order to improve the water guiding ability of the second guide rod 42, a hydrophobic film is attached to the second guide rod 42, and the hydrophobic film is made of a hydrophobic material. The cross section of the second guide rod 42 can be circular, rectangular or other shapes. In this embodiment, the second guide rod 42 adopts a circular structure. The top of the second guide rod 42 passes through the top plate of the box body 1 and extends out of the box body 1. The second guide rod 42 is rotatably arranged in the box body 1, and the rotation axis is perpendicular to the length direction of the box body 1.

[0049] Optionally, the adsorption hairs 41 are distributed along the length direction of the second flow guide rod 42, and the adsorption hairs 41 are arranged in multiple groups at intervals along the circumference of the second flow guide rod 42, which may be two groups, three groups, four groups or other numbers. In this embodiment, four groups of adsorption hairs 41 are arranged along the circumference of the second flow guide rod 42. The bottom end of the second flow guide rod 42 extends into the water collection tank 33.

[0050] Adjacent auxiliary water absorption components 4 are arranged side by side in at least two groups along the width direction of the box body 1. In this embodiment, three groups are arranged. It can be understood by those skilled in the art that the number of auxiliary adsorption components can be appropriately adjusted according to the size of the box body 1, and the number can be increased or decreased accordingly.

[0051] In order to facilitate the fluidity of the water drops on the adsorption hair 41 , the adsorption hair 41 is gradually inclined downward from one end away from the second guide rod 42 to the other end close to the second guide rod 42 .

[0052] After the air containing water mist passes through the water mist recovery mechanism 3, there is usually still a certain amount of water vapor in the air. In order to further reduce the water vapor content of the air input into the air cooler and improve the cooling water recovery effect, an auxiliary water absorption component 4 is arranged between the water mist recovery mechanism 3 and the air outlet 12. When the air containing water vapor passes through the adsorption hairs 41, the water droplets on the adsorption hairs 41 are condensed and adhered to the adsorption hairs 41. Some water droplets on the adsorption hairs 41 gather on the second guide rod 42, and the ice flows downward into the water collection tank 33 through the second guide rod 42.

[0053] See also Figure 5A cleaning plate 6 for contacting the adsorbent hair 41 is fixedly arranged in the vertical direction in the box body 1. The top wall of the cleaning plate 6 is fixedly connected to the top wall of the box body 1, which can be welded or bonded. The cleaning plate 6 is arranged in the middle of two adjacent second guide rods 42. The adsorbent hair 41 can contact the cleaning plate 6. A driving assembly 5 for driving the second guide rod 42 to rotate is arranged on the box body 1. The driving assembly 5 includes a gear 51, a toothed belt 52 and a motor 53. A gear 51 is fixedly arranged on one end of the second guide rod 42 extending from the top of the box body 1. In this embodiment, the three second guide rods 42 are all provided with gears 51. The toothed belt 52 is sleeved on the three gears 51, and the toothed belt 52 is meshed with the gear 51. The motor 53 is fixedly arranged on the top wall of the box body 1, and the output shaft of the motor 53 is drivingly connected to any second guide rod 42. Optionally, the motor 53 may be connected to the second flow guide rod 42 via a speed reducer, or may be directly connected to the second flow guide rod 42 , that is, the output shaft of the motor 53 is coaxially and fixedly connected to the second flow guide rod 42 .

[0054] During operation, the motor 53 drives the toothed belt 52 to rotate, and then drives the gear 51 and the second guide rod 42 to rotate, and drives the adsorption hair 41 to rotate. During the rotation of the adsorption hair 41, it constantly contacts the cleaning plate 6, so that the excess water droplets on the adsorption hair 41 are scraped off by the cleaning plate 6, further improving the water absorption capacity of the adsorption hair 41.

[0055] When the ambient temperature is high, such as in summer, in order to improve the heat exchange efficiency of the air cooler, the air flow rate at the air inlet of the air cooler is usually increased to improve the heat exchange effect, which will increase the fan power and increase energy consumption. Moreover, when the ambient air temperature is high and the temperature difference between the air temperature and the oil and gas is close, the heat exchange effect is not good.

[0056] The present application connects a cooling device to the air inlet end of the air cooler, and the outside air first enters the box body 1 through the air inlet 11 of the box body 1, and the air is sprayed and cooled by the spray assembly 2. Specifically, the water pump 221 pumps the cooling water in the water storage tank 13 into the annular water pipe 23, and then sprays it out through two groups of atomizing nozzles 21 to form two water curtain walls. The hot air passes through the water curtain walls to achieve cooling. When the air with water mist passes through the water mist recovery mechanism 3, the gas and liquid are separated, so that the water mist in the air is recovered into the water collection tank 33 and the water storage tank 13, and is pumped to the atomizing nozzle again by the water pump 221 for spraying, so as to achieve the purpose of recycling cooling water and reduce the water vapor content in the air. Specifically, the fins cooperate with the adsorption hairs 41 to effectively improve the adsorption effect of water mist.

[0057] The embodiment of the present application further discloses an air cooler, comprising a cooling device, wherein an air outlet 12 of a box body 1 of the cooling device is connected to an input end of the air cooler.

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
