Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a fixing device and an air conditioner outdoor unit. Background Art

[0002] In the existing air conditioner outdoor unit condenser installation technology, the condenser is usually installed on the chassis. Specifically, the bottom of one side of the condenser is tightly connected to the chassis by screws to ensure its stability; while the middle part is connected to the middle partition by screws to enhance the stability of its overall structure. In addition, the slot design on the motor bracket is cleverly used to fix the middle area of ​​the condenser, effectively preventing it from moving forward and backward during operation.

[0003] However, this installation method has a problem: the other side of the condenser has a bent structure, which makes it impossible to fix this area with the chassis block. In order to make up for this defect, currently only two wire ties are used to bind the double-row condensers to each other in order to achieve a certain fixing effect.

[0004] However, this fixing method is not stable, especially during transportation and handling. Once the air conditioner outdoor unit is subjected to external impact or vibration, the other side of the condenser is prone to displacement due to the lack of stable fit with other parts. This displacement may cause the U-tube of the condenser to collide with the shell and chassis, causing deformation of the condenser fins, damage to the heat exchange tubes, and even serious problems such as fluorine leakage.

[0005] Therefore, the existing condenser installation technology has obvious deficiencies, and a more stable and reliable installation solution is urgently needed to solve this problem and ensure the safety and stability of the air conditioner outdoor unit during transportation and use.

[0038] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0039] See also Figure 1 and Figure 2 The embodiment of the utility model provides a fixing device 10 for fixing the side and chassis of a condenser 20. The condenser 20 is installed above the chassis. The condenser 20 is provided with a heat exchange tube 21 (i.e., a U tube). The heat exchange tube 21 protrudes along the side of the condenser 20 to form a plurality of vertically arranged protrusions 211. The fixing device 10 comprises: a first plate 11, the first plate 11 is installed on the side of the condenser 20, and a plurality of hollow portions 111 corresponding to the protrusions 211 are provided on the first plate 11, so that each protrusion 211 passes through the hollow portion 111; a second plate 12, one side of the second plate 12 is connected to one side of the first plate 11, and the lower end of the second plate 12 is fixed to the chassis. In this embodiment, the hollow portion 111 is a hollow area formed on the first plate 11 to cooperate with the protrusion 211, and is arranged on the first plate 11 in a shape that matches the arrangement of the protrusion 211, that is, there are multiple hollow portions 111 and they are arranged at intervals along the vertical direction. The hollow portion 111 can be circular, square, diamond-shaped, or waist-shaped. Preferably, in this embodiment, it can be made into a waist-shaped shape by carving, cutting, perforating or other processing means.

[0040] The first plate 11 and the second plate 12 effectively fix the side and the bottom plate of the condenser 20, significantly enhancing the stability of the condenser 20 in the overall structure and avoiding the displacement of the condenser 20 due to external forces during transportation and handling. Since the heat exchange tubes 21 of the condenser 20 protrude along the side to form a plurality of vertically arranged protrusions 211 (i.e., the ends of the U tubes), these protrusions 211 pass through the hollow portions 111 on the first plate 11, thereby achieving a close combination of the condenser 20 and the fixing device 10. Such a design not only ensures the fixation of the condenser 20, but also effectively prevents the deformation of the fins of the condenser 20, the flattening of the U tubes, or the leakage of fluorine caused by external forces.

[0041] Furthermore, the width of the second plate 12 is greater than the protruding length of the protruding portion 211. In this embodiment, the wider design of the second plate 12 means that it can cover and support a larger area of ​​the side of the condenser 20, while covering the protruding portion 211. When the width of the second plate 12 is large enough, it can be more firmly fixed on the chassis, which further enhances the stability of the side of the condenser 20, and when the air conditioner outdoor unit is hit by external force, the second plate 12 can protect the U-tube, and also improve the rigidity and strength of the entire structure.

[0042] In one embodiment, the height of the second plate 12 is located at the first U-tube, ensuring that the upper end of the second plate 12 does not exceed the uppermost end of the evaporator, and the lower end of the second plate 12 is flush with the chassis. By setting the height of the second plate 12 at the first U-tube, the second plate 12 can be effectively prevented from interfering or colliding with other components on the upper part of the evaporator, ensuring that the spatial layout between the condenser 20, the evaporator and the fixing device 10 is reasonable and will not interfere with each other, thereby ensuring the normal operation of the air conditioner outdoor unit.

[0043] like Figure 3 and Figure 4 As shown, further, the size of the hollow portion 111 is larger than the size of the protruding portion 211, and the gap between the hollow portion 111 and the protruding portion 211 is larger than 2 mm. In this embodiment, the slot size of the hollow portion 111 is larger than the size of the protruding portion 211, and a certain gap is maintained with the protruding portion 211, and the gap is not less than 2 mm. In this way, during the operation of the air conditioner outdoor unit, even if the vibration is large, it can effectively prevent the hollow portion 111 and the protruding portion 211 from rubbing against each other, resulting in the edge of the hollow portion 111 wearing through the protruding portion 211.

[0044] like Figure 5As shown, further, the fixing device 10 also includes: a third plate, the third plate is fixedly connected to the other side of the second plate 12, and the third plate is opposite to the first plate 11. In this embodiment, by introducing the third plate and fixing it to the other side of the second plate 12, forming a relative position relationship with the first plate 11, the entire fixing device 10 forms a more stable frame structure. Such a design strengthens the connection between the side of the condenser 20 and the chassis, and at the same time increases the overall strength of the fixing device 10. When the side of the condenser 20 is displaced by external force, the third plate can contact the outer shell of the air conditioner outdoor unit in advance, thereby protecting the condenser 20.

[0045] In a more specific application embodiment, the width of the third plate can be adjusted according to the actual protection effect. Preferably, the third plate is designed to have a 4mm wide fold, which can save manufacturing costs and achieve the best protection effect.

[0046] In one embodiment, the first plate 11, the second plate 12 and the third plate are an integrated structure, and the first plate 11 and the third plate are vertically connected to both sides of the second plate 12. The design of the integrated structure of the first plate 11, the second plate 12 and the third plate allows the various parts of the fixture 10 to be tightly combined, without additional connectors or interfaces, and there is no need to assemble multiple parts during the manufacturing process, which greatly simplifies the manufacturing process. At the same time, during installation, there is no need to fix each plate separately, and the entire fixture 10 only needs to be fixed to the side of the chassis and the condenser 20 at one time, thereby improving the installation efficiency.

[0047] Furthermore, since the number of connectors and interfaces is reduced, the integrated structure also reduces the risk of the fixing device 10 becoming loose or damaged during long-term use, thereby reducing the frequency of maintenance and replacement and reducing maintenance costs.

[0048] Further, such as Figure 3 As shown, the upper and lower ends of the first plate 11 are provided with a yielding structure 112, which is used to yield at least one protrusion 211 at the upper and lower ends, respectively. In order to allow the fixing device 10 to be smoothly assembled into the protrusion 211 of the condenser 20, the first plate 11 needs to be bent or deformed, that is, the upper and lower ends of the first plate are designed to be yielding structures 112. Specifically, the corners of the two yielding structures 112 are both arc-shaped transitions, which can effectively prevent the sharp edges of the right angles from damaging the U-tube. At the same time, in order to avoid friction or interference between the first plate 11 and the protrusion 211, a certain gap needs to be reserved between the first plate 11 and the protrusion 211. These gaps can ensure that the sharp edges of the first plate 11 will not collide with the U-tube when the fixing device 10 is installed, and when the air conditioner outdoor unit is subjected to external force, and also make the heat exchange effect of the U-tube better. Therefore, in the actual design, the gap between the edge of the yielding structure 112 and the U-tube is not less than 2mm.

[0049] Furthermore, the upper end of the first plate 11 is designed as a giving structure 112, and the giving structure 112 is designed between the first and second protrusions 211 from the top to the bottom, and the lower end of the first plate 11 is also designed as a giving structure 112, and the giving structure 112 is located between the last and second protrusions 211. Due to the existence of the giving structure 112, when the installer fixes the fixing device 10 to the side of the condenser 20, it can be more convenient to align and position, which helps to reduce the adjustment and correction work during the installation process and improve the installation efficiency.

[0050] like Figure 4 As shown, the edge of the hollow portion 111 is provided with a first inner flange 1111, and / or the edge of the first plate 11 is provided with a second inner flange 113. Preferably, the inner flanges are provided at the edge of the hollow portion 111 and the edge of the first plate at the same time, which can not only enhance the strength of the fixture 10, but also effectively prevent the sharp edge of the first plate 11 from damaging the U-tube and scratching the installer when the fixture 10 is assembled to the side and chassis of the condenser 20, thereby causing safety hazards.

[0051] Further, combined with Figure 3 and Figure 6 As shown, a first through hole 114 is provided on the first plate 11, and a detachable connector is installed on the first through hole 114 between the first plate 11 and the side of the condenser 20, and a second through hole 121 is provided on the lower end of the second plate 12, and a detachable connector is installed on the second through hole 121 between the lower end of the second plate 12 and the chassis. In this embodiment, the first through hole 114 and the second through hole 121 can be screw holes. Preferably, a screw hole is designed in the blank area of ​​the second and third U tubes at the upper end of the first plate 11, and a screw hole is designed in the blank area of ​​the penultimate and second U tubes at the lower end of the first plate 11. The screw hole is designed in the middle of the blank area as much as possible, so as to effectively avoid the situation of damaging the copper tube when screwing. At the same time, a screw hole is designed in the middle of the area where the lower end of the second plate 12 coincides with the edge of the chassis, and the lower end of the second plate 12 is fixed to the chassis with a screw.

[0052] Alternatively, if the fixing effect of the screw at the lower end of the second plate 12 is not good, a screw hole can be designed at the upper edge of the second plate 12, and the outer shell of the air conditioner outdoor unit can be fixedly connected with a screw. If the upper and lower ends of the first plate 11 and the upper and lower ends of the second plate 12 are not firm enough after being fixed with four screws (i.e., the side of the condenser 20 still shifts), a clearance groove 123 can be opened at the upper and lower ends of the edge of the side of the condenser 20, and the outer shell of the air conditioner outdoor unit can be inserted into the corresponding groove to increase the reliability of the fixation.

[0053] Further, such as Figure 6 As shown, a rib strip 122 is provided in the middle area of ​​the second plate 12. In this embodiment, the middle area of ​​the second plate 12 adopts a structural design of horizontal and vertical cross rib strips 122, which include vertical rib strips and transverse rib strips. The vertical rib strips are arranged along the length direction of the second plate 12, and a plurality of transverse rib strips are arranged and spaced on both sides of the vertical rib strips. The rib strip width can be determined according to the actual effect and the width of the second plate 12. The rib strips 122 do not need to be too dense, but can be evenly dispersed. The design of the rib strip 122 can significantly enhance the rigidity and structural stability of the second plate 12. When the air conditioner outdoor unit is subjected to external force, the rib strip 122 can effectively resist deformation and distortion, maintain the stability and reliability of the fixing device 10, improve the connection tightness and fixing effect between the fixing device 10 and the side and chassis of the condenser 20, and help prevent the condenser 20 from loosening or displacement during long-term use.

[0054] An air conditioner outdoor unit includes a condenser 20 and a chassis, wherein a fixing device 10 as described above is installed between the side of the condenser 20 and the chassis.

[0055] Since the air conditioner outdoor unit is installed outdoors and is exposed to high temperature, sun exposure and rain for a long time, this embodiment uses a material with good corrosion resistance and not easy to produce chemical reactions. Since the fixing device 10 mainly plays the role of fixing the side of the condenser 20, its own strength should be high and not easy to change. Preferably, a hot-dip galvanized sheet material is used, and specifically Q235A 0.6X1100XC hot-dip galvanized sheet material can be used. Q235A is a common carbon structural steel with good strength, plasticity and toughness, easy to process and weld, and is usually used in manufacturing industries such as construction, bridges, vehicles, ships, and pressure vessels. The "A" represents the quality grade of the steel. Generally speaking, the sulfur and phosphorus content of grade A steel is lower than that of grade B and grade C, so its quality is relatively better. "0.6" refers to the thickness of the steel plate, in millimeters. Therefore, the thickness of the steel plate used in the fixing device is 0.6 mm. "1100" is usually the width mark of the steel plate, in millimeters. Therefore, the width of the steel plate used in the fixing device is 1100 mm. The "C" here may be an identifier for the length of the steel plate, but the specific value is not given. Usually "X" does not represent a specific value or unit. Here, "X" may be a placeholder to distinguish thickness, width and length or other specifications that are not clearly stated. Since only the thickness (0.6) and width (1100) are given in the specification description, and the specific value of the length (C) is not given, "X" may just be used to maintain the consistency of the format or as a separator.

[0056] The utility model also provides an installation method of the fixing device 10. Specifically, take the fixing device 10, align the hollow portion 111 on the fixing device 10 with the U-tube on the side of the condenser 20 from bottom to top, then take two screws, use the screws to fix the first plate 11 on the side of the condenser 20, then take another screw to fix the second plate 12 to the chassis, and finally the fixing device 10 firmly fixes the side of the condenser 20 to the chassis.

[0057] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
