Description

Technical Field

[0001] This utility model relates to the field of air cooler technology, and in particular to a dual-sided air cooler with an easy-to-remove filter. Background Technology

[0002] Evaporative air coolers are divided into industrial evaporative air coolers and household evaporative air coolers. Industrial evaporative air coolers are generally used in cold storage and cold chain logistics refrigeration environments, while household evaporative air coolers, also known as water-cooled air conditioners, are evaporative cooling and ventilation units that integrate cooling, ventilation, dust prevention, and deodorization. In addition to bringing fresh air and lowering the temperature in factory workshops, public places, and commercial and entertainment venues, evaporative air coolers also have the important characteristics of being energy-saving and environmentally friendly.

[0003] After a period of use, the filter screen of an evaporative air cooler accumulates a lot of dust and needs to be removed for cleaning. However, existing filters are usually fixed with multiple bolts, which requires loosening and removing all the bolts during disassembly. Removing multiple bolts takes a long time and is inconvenient for disassembling the filter screen. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where removing multiple fixing bolts takes a long time and is inconvenient for disassembling the filter screen. Therefore, this invention proposes a dual-sided air-cooled fan that facilitates the removal of the filter screen.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a dual-sided air-cooled fan with easy-to-remove filter screen, including a housing, with slots on both sides of the housing, a filter screen in each slot, and a fixing mechanism for limiting the filter screen in each slot;

[0007] The fixing mechanism includes a fixing frame located within the slot and in contact with the filter screen. Two parallel grooves are formed on both sides of the fixing frame. A movable block is slidably connected to each groove, and a rod is fixedly connected to each movable block. A spring is fixedly connected to each movable block, and one end of each spring is fixedly connected to the groove. The spring is located outside the rod. Several limiting grooves are formed on the inner wall of the slot, and each rod engages with a corresponding pair of limiting grooves.

[0008] Preferably, each of the movable blocks on the same side is fixedly connected to a connecting plate, and there is a gap between the connecting plate and the fixed frame.

[0009] Preferably, a guide mechanism is fixedly connected between the two connecting plates. The guide mechanism includes a guide rod, one end of which is fixedly connected to one of the connecting plates, and the other end of which is slidably connected to a grooved post, which is fixedly connected to the other connecting plate.

[0010] Preferably, the guide rod is a metal guide rod.

[0011] Preferably, both sides of the interior of the housing are connected to an air guiding mechanism. The air guiding mechanism includes a baffle, which is fixedly connected to the housing. Several air guiding pipes are connected to the baffle at equal intervals along the length direction, and each air guiding pipe is inclined towards the heat exchanger.

[0012] Preferably, the baffle and the air guide tube are an integral structure.

[0013] The present invention provides a dual-sided air-cooled fan with an easy-to-remove filter, the advantages of which are:

[0014] When disassembling the filter, pull the connecting plate outward. The connecting plate moves the movable block, which in turn moves the insert rod. After moving a certain distance, the insert rod retracts into the groove. At this point, the insert rod separates from the limiting groove, and the fixing frame loses its fixation. The fixing frame can then be removed from the groove, and the filter can be removed. This process is quick and easy. Attached Figure Description

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example 1: Refer to Figure 1-5 A dual-sided air-cooled fan with easy-to-remove filter screen includes a housing 1, an axial flow fan 2 connected to the housing 1, mounting brackets 3 connected to both sides of the interior of the housing 1, a heat exchanger 4 connected to each mounting bracket 3, slots 5 opened on both sides of the housing 1, a filter screen 6 provided in each slot 5, and a fixing mechanism 7 for limiting the filter screen 6 connected to each slot 5.

[0023] The fixing mechanism 7 includes a fixing frame 71, which is located inside the slot 5 and contacts the filter screen 6. Two parallel grooves 72 are provided on both sides of the fixing frame 71. A movable block 73 is slidably connected to each groove 72. A rod 74 is fixedly connected to each movable block 73. A spring 75 is fixedly connected to each movable block 73. One end of each spring 75 is fixedly connected to the groove 72. The spring 75 is located outside the rod 74. Several limiting grooves are provided on the inner wall of the slot 5. Each rod 74 cooperates with a corresponding limiting groove. A connecting plate 76 is fixedly connected between the movable blocks 73 on the same side. There is a gap between the connecting plate 76 and the fixing frame 71.

[0024] Working process:

[0025] When disassembling the filter screen 6, pull the connecting plate 76 outward. The connecting plate 76 pulls the movable block 73 to move. The movable block 73 pulls the insertion rod 74 to move. After the insertion rod 74 moves a certain distance, it retracts into the groove 72. At this time, the insertion rod 74 separates from the limiting groove, and the fixing frame 71 loses its fixation. Remove the fixing frame 71 from the slot 5, and then remove the filter screen 6. The process is quick and easy.

[0026] When installing the filter screen 6, pull the connecting plate 76 to retract the insertion rod 74 into the groove 72. At this time, the spring 75 is compressed to generate elastic force, placing the fixing frame 71 on the slot 5. Release the connecting plate 76, and the elastic force generated by the spring 75 pushes the insertion rod 74 into the limiting groove to fix the limit, thereby fixing the filter screen 6.

[0027] Example 2: In Example 1, when the connecting plate 76 is pulled to move, the movement of the connecting plate 76 cannot be limited, which easily leads to the misalignment and separation of the movable block 73 and the groove 72. (Refer to...) Figure 4 As another preferred embodiment of this utility model, the difference from embodiment 1 is that a guide mechanism 8 is fixedly connected between the two connecting plates 76. The guide mechanism 8 includes a guide rod 81, which is a metal guide rod. One end of the guide rod 81 is fixedly connected to one of the connecting plates 76, and the other end of the guide rod 81 is slidably connected to a grooved post 82. The grooved post 82 is fixedly connected to the other connecting plate 76. After the connecting plate 76 moves, relative sliding is found between the guide rod 81 and the grooved post 82, which limits the connection plate 76 and prevents the movable block 73 from being misaligned and separated from the groove 72.

[0028] Example 3: Refer to Figure 2-3 As another preferred embodiment of this utility model, the difference from embodiment 1 is that both sides of the interior of the box 1 are connected to the air guiding mechanism 9. The air guiding mechanism 9 includes a baffle 91, which is fixedly connected to the inside of the box 1. Several air guiding pipes 92 are connected at equal intervals along the length direction on the baffle 91. Each air guiding pipe 92 is inclined towards the heat exchanger 4. The baffle 91 and the air guiding pipe 92 are an integral structure. The gas drawn by the axial flow fan 2 enters the box 1. After the gas in the box 1 comes into contact with the baffle 91, it is guided by the air guiding pipe 92 and enters the heat exchanger 4, thereby improving the gas cooling effect.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
