They achieve the purpose of cooling by using the principle of air evaporation cooling. In existing industrial air coolers, the intake air directly blows on the water-permeable wet curtain. The stable flowing air has little disturbance to the liquid surface of the wet curtain, and the water evaporation effect is average, resulting in limited refrigeration effect and having certain room for improvement. Content of the Utility Model

[0003] Aiming at the problems in the background art, the purpose of the utility model is to provide an efficient refrigeration air cooler, which effectively solves the problems existing in the background art.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

The front and rear sides of the housing are provided with air inlets, and an air intake device is arranged at the air inlets. The air intake device includes multiple layers of rectangular air ducts arranged up and down. In the rectangular air ducts, two rows of V-shaped air guide plates are arranged in a staggered manner. Multiple V-shaped air ducts with outlets facing the inner cavity of the housing are formed between the two rows of air guide plates, and an air outlet corresponding to the outlet of the V-shaped air duct is arranged on one side of the rectangular air duct. Multiple vortex generators are symmetrically arranged in the V-shaped air ducts. The multiple vortex generators include rectangular columns and triangular columns.

[0016] Such as Figure 1 and Figure 2As shown in the figure, an efficient refrigeration air cooler according to this embodiment includes a housing 1, an air outlet duct 2 provided on the top surface of the housing 1, and a fan 3 provided in the air outlet duct 2. The air outlet duct 2 is L-shaped. The inlet of the air outlet duct 2 is connected to the inner cavity of the housing 1 through the top surface of the housing 1. The outlet of the air outlet duct 2 faces forward. The fan 3 is an induced draft fan. Both the front and rear sides of the housing 1 are provided with air inlets, and an air intake device is arranged in cooperation with the air inlets. The air intake device includes multiple layers of rectangular air ducts 4 arranged up and down. In the rectangular air ducts 4, two rows of V-shaped air guide plates 5 are arranged in a staggered manner. The orientations of the two rows of air guide plates 5 are opposite, so that a plurality of V-shaped air ducts 6 with outlets facing the inner cavity of the housing 1 are formed between the two rows of air guide plates 5. An air outlet 7 corresponding to the outlet of the V-shaped air duct 6 is arranged on the inner side of the rectangular air duct 4. Multiple vortex generators are also symmetrically arranged in the V-shaped air duct 6. The multiple vortex generators include a rectangular column 8 and a triangular column 9. The rectangular column 8, the triangular column 9, and the air guide plate 5 are all of the same height as the inner cavity of the rectangular air duct 4. Based on the air flow direction, the rectangular column 8 is located upstream of the triangular column 9, and one vertical edge of the rectangular column 8 faces the air intake direction. The cross-section of the triangular column 9 is approximately triangular, and the base of the triangle faces the rectangular column 8;

[0017] A water tank 10, a filter cotton 11, a packing layer 12, and a spray pipe layer 13 are sequentially arranged in the housing 1 from bottom to top. The height difference between the filter cotton 11 and the water tank 10 is not greater than 20 cm. The water droplets dripping from the packing layer 12 first fall onto the filter cotton 11 and then enter the water tank 10, avoiding the noise caused by the direct impact of the water discharged from the packing layer 12 on the liquid surface of the water tank 10. The filter cotton 11 can be clamped by two layers of metal meshes up and down. The metal meshes are detachably connected to the inner cavity of the housing 1 through bolts. To facilitate the replacement of the filter cotton 11, a maintenance door can be opened on the left or right side of the housing 1; the spray pipe layer 13 is connected to the water tank through a water supply pipe 14, and a water pump is arranged on the water supply pipe 1; a water tank make-up water pipe 15 is also arranged on the housing 1, and a valve is arranged on the water tank make-up water pipe 15.

[0018] In order to ensure the cleanliness of the outside air intake and prevent dust and impurities from entering the packing layer 12 and accumulating to affect the heat exchange and evaporation efficiency, a rain area spray pipe 16 is arranged above the outer side of the air intake device. The rain area spray pipe 16 sprays downward, forming a rain area outside the air intake device. The outside air passes through the rain area and then enters the air intake device. Rain area water tanks 17 corresponding to the rain area spray pipe 16 are respectively arranged on the front and rear sides of the housing 1. The rain area spray water falls into the rain area water tanks 17. The rain area spray pipe 16 and the rain area water tanks 17 are connected through a water pipe 18, and a water pump is also arranged on the water pipe 18.

[0019] In order to prevent the rain area water from entering the housing 1 and ensure the cleanliness of the water flow inside the housing 1, the rectangular air duct 4 is in an inclined posture with the inner side high and the outer side low. The water flow entering the rectangular air duct 4 under the influence of wind cannot always pass through the V-shaped air duct 6 upward, but converges under the action of gravity and drips back into the rain area water tank 17 outside the air intake device.

[0020] The working principle of this embodiment is as follows:

[0021] During operation, the outside air passes through the rain area from the front and back sides under the action of the fan 3 and enters the V-shaped air duct 6. Under the disturbance of the multi-vortex generator, many air flow vortices are formed downstream. When the two air flow vortices in the V-shaped air duct 6 are discharged, they collide and break, making the air outlet of the V-shaped air duct 6 become a turbulent flow state gas. This state of gas then enters the packing layer 12 in the housing 1 and contacts with water. The water evaporates and absorbs heat to reduce the gas temperature, and then it enters the outlet air duct 2 upward and is discharged. Compared with the prior art, in this embodiment, two front and rear air intake devices are applied to output turbulent intake air to the inner cavity of the housing 1. Compared with laminar intake air, turbulent intake air has a better disturbance effect on the liquid surface in the packing layer 12 and a better heat exchange effect. The temperature of the gas passing through the packing layer 12 in this way is generally 1°C - 2°C lower than the wet curtain outlet temperature of traditional industrial cooling fans. This embodiment can send out gas with a lower temperature and is suitable for popularization and use.

[0022] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better explain the principles of the present invention and its practical application, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.
