Description

Technical Field

[0001] This application relates to the field of air cooler fans, and more particularly to an air cooler with an adjustable fan mounting angle. Background Technology

[0002] An evaporative air cooler is an air cooler suitable for various industrial refrigeration and cold storage facilities. It lowers the temperature through heat exchange. The standard design of evaporative air coolers has a fan tilt angle of 0° and the fan angle is not adjustable. During use, because the fan and the evaporative air cooler body are fixedly connected, the direction of the airflow from the fan is always in one direction. In actual use, the standard evaporative air cooler design sometimes fails to meet the required range, and the temperature distribution in the cold storage is uneven. Utility Model Content

[0003] To address the issue of non-adjustable fan angle, this application provides an air cooler with an adjustable fan installation angle.

[0004] The air cooler with an adjustable fan installation angle provided in this application adopts the following technical solution:

[0005] An adjustable fan mounting angle air cooler includes an air cooler body, with mounting slots symmetrically opened on the outer side of the air cooler body. Fan bodies are movably connected to the interior of each mounting slot. Side housings are fixedly connected to both sides of the air cooler body, and adjustment components for adjusting the airflow direction of the fan bodies are provided inside each side housing.

[0006] By adopting the above technical solution, the adjustment component can adjust the installation angle of the fan body, which can effectively increase the range and change the airflow direction to avoid blowing directly on people. This design can increase the operator's working comfort.

[0007] Preferably, an auxiliary shaft is fixedly connected between the two fan bodies, and a drive shaft is fixedly connected to the side of the two fan bodies that are far apart from each other. The ends of the two drive shafts that are far away from the fan bodies pass through the side casings on both sides of the air cooler body.

[0008] By adopting the above technical solution, the use of the drive spindle and auxiliary shaft can simultaneously control two fans and maintain their synchronization.

[0009] Preferably, the adjustment assembly includes a threaded rod 1 that is rotatably connected through the inside of the side housing. A synchronous motor is provided on the outer wall of the side housing. One end of the threaded rod 1 located outside the side housing is fixedly connected to the output shaft end of the synchronous motor. A threaded rod 2 that is rotatably connected to the inner wall of the side housing and is vertically parallel to the threaded rod 1. A first slider and a second slider are respectively threadedly connected to the surfaces of the threaded rod 1 and the threaded rod 2.

[0010] By adopting the above technical solution, the rotation of threaded rod one and threaded rod two can drive the first slider and the second slider to move, thereby adjusting the angle of the fan body.

[0011] Preferably, the outer surfaces of the threaded rod one and the threaded rod two near the synchronous motor are respectively fixedly connected to meshing gear one and gear two.

[0012] By adopting the above technical solution, the meshing of gear one and gear two can cause threaded rod one and threaded rod two to rotate in opposite directions.

[0013] Preferably, auxiliary plates are fixedly connected to both ends of the drive spindle, the drive spindle is fixedly connected to the middle of the auxiliary plates, and connecting rods that are hinged to one side of the first slider surface and one side of the second slider surface are respectively connected to both ends of the auxiliary plates.

[0014] By adopting the above technical solution, the direction and height of the connecting rod's tilt angle can be changed, thereby determining the angle of the fan body's elevation.

[0015] Preferably, the threaded rod one, the first slider, the threaded rod two, and the second slider are symmetrically arranged with the drive spindle as the center line.

[0016] Preferably, the top and bottom of the fan body and the mounting slot are both arc-shaped, and the shape of the fan body is adapted to the shape of the mounting slot.

[0017] By adopting the above technical solution, the arc shape of the mounting slot can adapt to the rotation of the fan body, so that it will not obstruct the rotation of the fan body.

[0018] Preferably, the top and bottom of the mounting groove are provided with limiting grooves, and the top and bottom of the fan body are fixedly connected with limiting plates, which slide inside the limiting grooves.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] The angle of the fan body is adjusted by moving the first slider through the rotation of the first threaded rod, allowing the airflow direction of the fan body to be changed during use. The angle and height of the connecting rod are determined by adjusting the movement of the first slider, which can be selected according to specific usage and operating conditions. The symmetrical arrangement of the first and second threaded rods allows force to be applied to both the upper and lower ends of the fan body during adjustment, making the force on the fan more even and balanced during rotation, resulting in greater stability. The movement of the first and second sliders tilts the connecting rod and the auxiliary plate, forming two triangular shapes symmetrical about the drive shaft. These two symmetrical triangular structures support each other, further enhancing the overall stability of the fan body. Attached Figure Description

[0029] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0030] This application discloses a cooler with an adjustable fan installation angle.

[0031] Reference Figure 1 , Figure 4 An adjustable fan mounting angle air cooler includes an air cooler body 1, a mounting groove 6 is opened on the side of the air cooler body 1 near the drive shaft 5, a fan body 2 is movably connected inside the mounting groove 6, and side housings 3 are fixed to both sides of the air cooler body 1 and the two side housings 3 are symmetrically arranged. The top and bottom of the fan body 2 are arc-shaped, and the top and bottom of the mounting groove 6 are also arc-shaped.

[0032] During the rotation of the fan body 2, it moves along the arc trajectory of the mounting groove 6, so that the seal between the air cooler body 1 and the fan body 2 can be maintained during the movement. This allows the air to collide inside the air cooler body 1 and then directly exit from the fan body 2, thereby reducing air volume loss, improving the efficiency of return air, and increasing the cooling effect.

[0033] Reference Figure 1 , Figure 4The top and bottom of the mounting slot 6 are provided with limiting slots 7. The movement range of the fan body 2 can be limited by the limiting slots 7. The limiting plate 8 slides inside the limiting slot 7. The two limiting plates 8 are symmetrically fixedly connected to the upper and lower surfaces of the fan body 2 respectively. The size of the limiting plate 8 is adapted to the limiting slot 7. The limiting plate 8 will not deviate during the sliding process.

[0034] During adjustment, the fan body 2 will drive the limiting plate 8 to rotate together. The limiting plate 8 slides inside the limiting groove 7. The top and bottom of the fan body 2 move along the arc track of the mounting groove 6 to improve its sealing performance, prevent airflow loss, and effectively increase part of the range.

[0035] Reference Figure 1 , Figure 4 An auxiliary shaft 9 is fixedly connected between the two fan bodies 2. A drive main shaft 5 is fixedly connected to the side of the two fan bodies 2 away from the auxiliary shaft 9. The end of the drive main shaft 5 away from the auxiliary shaft 9 passes through the interior of the side casing 3. The drive main shaft 5 and the auxiliary shaft 9 are rotatably connected to the interior of the air cooler body 1. The drive main shaft 5 and the auxiliary shaft 9 both pass through the interior of the air cooler body 1.

[0036] When the main shaft 5 rotates, the auxiliary shaft 9 can simultaneously drive the two fan bodies 2 to rotate, allowing the tilt angle of all fan bodies 2 to be adjusted at once, achieving fast and accurate adjustment.

[0037] Reference Figure 2 , Figure 3 The air cooler body 1 has adjustment components 4 inside the side housings 3 on both sides, used to adjust the angle of the fan body 2. The airflow direction of the fan body 2 can be adjusted by using both adjustment components 4 simultaneously. The side housings 3 protect the adjustment components 4 and prevent their structure from being directly exposed. The adjustment component 4 includes a threaded rod 41, which is rotatably connected inside the side housing 3 to facilitate the connection and control of the synchronous motor 42 with the threaded rod 41. The synchronous motor 42 is located on the outer wall of the side housing 3, and the output shaft end of the synchronous motor 42 is fixedly connected to the end of the threaded rod 41 that extends outside the side housing 3.

[0038] The synchronous motor 42 drives the threaded rod 41 to rotate, and the rotation of the threaded rod 41 moves the first slider 44 to adjust the angle of the fan body 2. The user can select the angle of the fan body 2 according to the specific usage and operating status.

[0039] Reference Figure 2 , Figure 3A threaded rod 43 is rotatably connected to the inner wall of the side housing 3. The threaded rod 43 is vertically parallel to the threaded rod 41, and is located below the threaded rod 41. A first slider 44 is threadedly connected to the surface of the threaded rod 41, and a second slider 45 is threadedly connected to the surface of the threaded rod 43. The first slider 44 and the threaded rod 41 are symmetrically arranged with the drive spindle 5 as the center line, and with respect to the threaded rod 43 and the second slider 45. A gear 46 is fixedly connected to the outer surface of the end of the threaded rod 41 near the synchronous motor 42. Gear 47 is fixedly connected to the outer surface of the end of threaded rod 43 near the synchronous motor 42, and gear 46 and gear 47 are meshed together. The meshing connection allows threaded rod 41 and threaded rod 43 to rotate in opposite directions, so that the angle of the fan body 2 can be adjusted through the upper and lower ends of the fan body 2. In this way, the symmetrical arrangement of threaded rod 41 and threaded rod 43 can apply force to the upper and lower ends of one side of the fan body 2 at the same time, which can provide a smoother rotation and reduce the shaking or instability of the fan body 2 during the adjustment process.

[0040] The rotation of threaded rod 41 causes threaded rod 43 to rotate in the opposite direction to threaded rod 41 via gear 46 and gear 47. The opposite rotation of threaded rod 41 and threaded rod 43 causes the first slider 44 and the second slider 45 to move in opposite directions.

[0041] Reference Figure 2 , Figure 3 Auxiliary plates 49 are fixedly connected to both ends of the drive spindle 5. The two auxiliary plates 49 are located inside the two side housings 3 respectively, and the middle part of the auxiliary plates 49 is fixedly connected to the drive spindle 5. A connecting rod 48 is rotatably connected to one side of the surface of the first slider 44 and one side of the surface of the second slider 45 respectively. The ends of the two connecting rods 48 away from the first slider 44 and the second slider 45 are rotatably connected to the two ends of the auxiliary plates 49 respectively. In this way, when the first slider 44 and the second slider 45 move and adjust, the two connecting rods 48 will tilt. The auxiliary plates 49 tilt with the movement of the connecting rods 48. The tilt of the connecting rods 48 and the auxiliary plates 49 forms a triangle with the threaded rod 1 41 and the threaded rod 2 43. The triangular structure can evenly distribute the force, reduce stress concentration points, and prevent damage caused by excessive local force.

[0042] During the adjustment process, the reverse movement of the first slider 44 and the second slider 45 causes the auxiliary plate 49 to rotate around the drive spindle 5 as the center point through the tilting of the connecting rod 48, thereby driving the two fan bodies 2 to change their angle and wind direction at the same time, avoiding cold air blowing directly on the processing personnel and improving their comfort.

[0043] Among them, the synchronous motor 42 is existing technology, and its structural principle will not be described in detail. When the two synchronous motors 42 are used, they are controlled by a synchronous controller. The synchronous controller can automatically adjust the speed and position of the motors as needed to achieve synchronous movement.

[0044] The implementation principle of an adjustable fan installation angle air cooler according to an embodiment of this application is as follows: When adjusting the airflow direction of the fan body 2, the user starts the synchronous motor 42. The synchronous motor 42 drives the threaded rod 41 to rotate. The rotation of the threaded rod 41 drives the gear 46 to rotate. The rotation of the gear 46 drives the gear 47 meshing with it to rotate. The rotation of the gear 47 drives the threaded rod 43 to rotate in the opposite direction to the threaded rod 41. When the threaded rod 41 and the threaded rod 43 rotate, they drive the first slider 44 and the second slider 45 connected to them to move in the opposite direction, thereby driving the two connecting rods 48 to tilt and move in the opposite direction. The connecting rod 48 drives the auxiliary plate 49 to rotate, which in turn drives the drive shaft 5 to rotate. The drive shaft 5, through the auxiliary shaft 9, drives the two fan bodies 2 to adjust their airflow direction simultaneously, maintaining their synchronicity. This allows for the adjustment of the elevation angle of all fan bodies 2 at once, achieving rapid and accurate adjustment. The two fan bodies 2 rotate inside the mounting slot 6, maintaining the seal between the air cooler body 1 and the fan bodies 2 during rotation, reducing airflow leakage. During rotation, the two fan bodies 2 drive the limiting plate 8 to slide within the limiting slot 7, thereby restricting the movement of the fan bodies 2 and improving their stability.

[0045] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
