[0023] The present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0024] The directions mentioned in this specification are based on the directions shown in the drawings and only represent relative positions, not absolute positions.
[0025] like Figure 1 and Figure 2 As shown together, an air cooler with a spray device includes a bracket, and the bracket includes four vertically arranged support columns 10, and the four support columns 10 form a square frame. A spray box 38 is installed between the square frame formed by the four support columns 10, and the upper side of the spray box 38 is an open structure. The four corners of the spray box 38 are respectively fixed to the upper ends of the four support columns 10, and the spray device 30 is installed in the spray box 38. A cooling device 40 is installed at the top of the four support columns 10, and the cooling device 40 is located above the spray box 38 and is connected to the spray box 38. The lower part of the spray box 38 is connected to a bellows 22, and the lower end of the bellows 22 is installed with a fan 20. A shutter 50 is installed above the cooling device 40, and the opening angle of the shutter 50 is adjustable, so that the air volume can be adjusted by the shutter 50.
[0026] like Figure 1 and Figure 2 As shown together, the cooling device 40 includes a plurality of horizontally arranged fin tubes (not shown in the figure), the spray device 30 is located below the fin tubes, a medium inlet 42 communicating with the fin tubes is provided above one end of the cooling device 40, and a medium outlet 44 communicating with the fin tubes is provided below the other end of the cooling device 40. The cooled medium flows into the fin tubes from the medium inlet 42 and then flows out from the medium outlet 44. The heat of the medium flowing through the fin tubes is dissipated through the fin tubes and then taken away by the wind blown by the fan 20, thereby achieving the effect of cooling the medium.
[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown together, the spray device 30 includes a spray main pipe 32, one end of which extends out of the spray box 38 and is connected to the water source, and the other end of the spray main pipe 32 is a closed structure. The spray main pipe 32 is connected to multiple spray branch pipes 34, and multiple atomizing nozzles 36 are installed on each spray branch pipe 34. In this embodiment, the spray branch pipes 34 are preferably arranged on both sides of the spray main pipe 32 in the horizontal direction, and each spray branch pipe 34 located on the same side of the spray main pipe 32 is arranged in parallel. In this embodiment, the spray branch pipes 34 located on both sides of the spray main pipe 32 are preferably arranged symmetrically with respect to the vertical line passing through the center of the spray main pipe 32, and the spray branch pipes 34 located on both sides of the spray main pipe 32 are arranged in a V shape, and the angle of the V shape is an obtuse angle, that is, the spray branch pipes 34 located on both sides of the spray main pipe 32 are arranged upwardly inclined from the spray main pipe 32. In this embodiment, each atomizing nozzle 36 is preferably installed on the upper and lower sides of the spray branch pipe 34.
[0028] like Figure 1 and Figure 2 As shown together, in this embodiment, preferably two wind boxes 22 are provided. The two wind boxes 22 are arranged side by side below the spray box 38 and are respectively connected to the spray box 38. A fan 20 is installed below each of the two wind boxes 22.
[0029] like Figure 1 and Figure 2 As shown together, the working principle of the air cooler with a spray device of the utility model is as follows:
[0030] The air blown out by the fan 20 first enters the bellows 22, and then enters the spray box 38 after passing through the bellows 22. The spray device 30 sprays water mist. The temperature of the air will decrease after passing through the water mist, so that the temperature of the air entering the finned tube bundle is reduced by 3-4°C. At the same time, the air will also carry water mist into the finned tube bundle above for heat exchange. The air entering the bundle takes away the heat emitted by the bundle through its own temperature rise and the evaporation of water mist, so as to achieve the purpose of cooling. The size of the air volume can be adjusted by the shutter 50 on the bundle. The utility model effectively solves the problem that the high temperature in summer cannot meet the cooling requirements faced by the current air cooler. The atomizing nozzle 36 saves water as much as possible, and the spray device 30 is arranged in the bracket without taking up space.
[0031] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative work are all within the protection scope of the present invention.
