Description

Technical Field

[0001] The present application belongs to the technical field of air-conditioning systems, and specifically relates to an air-conditioner auxiliary support assembly and an air-conditioning system. Background Art

[0002] Some mechanical equipment often features an inner and outer box, with the inner box housed within the outer box. This includes the kitchen simulator in an aircraft auxiliary cooling system, or individual box structures, such as the outer box of a plate-fin heat exchanger in an evaporative cooling unit (CRU). Due to specific size limitations, the top of the outer box is suspended. When the outer box is too large or heavy, the top beam of the outer box typically experiences significant deformation, which not only affects product performance but also worsens over time, potentially leading to structural damage. Simply welding brackets to the outer box makes it difficult to fully support the outer box.

[0003] Usually, many devices use an electric-driven lifting device installed under the top beam of the outer box to solve the above technical problems. However, the use of the electric-driven lifting device is subject to certain restrictions. For example, when there is an inner box structure, the height difference between the inner and outer boxes is small. Even if the electric-driven lifting device is lowered to the lowest height during use, it is still higher than the height difference between the inner and outer boxes and cannot be installed between the inner and outer boxes for use; when the inner and outer box devices have special use requirements, such as not allowing live work, the electric-driven lifting device will no longer be applicable. Utility Model Content

[0004] Therefore, the present application provides an air conditioner auxiliary support assembly and an air conditioning system, which can solve the problem in the prior art that an electrically driven lifting device cannot be used to support an easily deformable air conditioner structure.

[0043] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0044] In the description of this application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of this application; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0045] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0046] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0047] See also Figures 1 to 6 As shown, according to an embodiment of the present application, an air conditioner auxiliary support assembly includes:

[0048] The fixed seat 1, the slider 2, the threaded rod 4 assembly and the supporting member 3, wherein the slider 2 and the fixed seat 1 are arranged to slide horizontally, the upper end surface of the slider 2 is set as an inclined first slope, and the supporting member 3 is in sliding engagement with the first slope; the threaded rod 4 assembly includes a threaded rod 4 passing through the slider 2 and a nut 41 threadedly connected to the threaded rod 4;

[0049] When the nut 41 rotates on the threaded rod 4 , the slider 2 slides on the fixing seat 1 , driving the supporting member 3 to move in the vertical direction, so that the supporting member 3 supports the portion to be supported of the air conditioner 7 .

[0050] The present application sets an air conditioner auxiliary support assembly under the part to be supported of the air conditioner 7, and drives the supporting member 3 to support the part to be supported by rotating the nut 41 to prevent the part to be supported from being deformed. In this way, the part to be supported of the air conditioner 7 can be supported when an electric-driven lifting device cannot be used, which has the beneficial effect of preventing its deformation.

[0051] This application achieves height adjustment through the combination of a nut 41 with a threaded rod 4 and other structural components, resulting in controllable dimensions. It is widely applicable, easy to install, and has low maintenance costs and good economic benefits. This solves the problem of a small height difference between the inner and outer boxes 5, where electric-driven lifting equipment is no longer suitable due to size limitations. The height difference can be controlled through the coordination of a mechanical linkage structure and manual adjustment, eliminating the limitations of equipment operating conditions such as those prohibiting live operation. This structural component is suitable for use in adverse environments such as humid environments, reducing maintenance costs and improving economic benefits.

[0052] The mechanism of the present application can be applied to devices with a certain height difference between two parts, such as the structure of the inner and outer boxes 5. When there is a certain height difference between the inner and outer boxes 5, due to the large size of the outer box 5, or due to reasons such as the material and wall thickness, the weight of the top crossbeam structure of the outer box 5 will be relatively large, which makes it easier to deform. When the deformation is large, it will not only affect the appearance of the structure, but in severe cases, it may cause the top crossbeam structure to be insufficiently strong and damaged. It is difficult to prevent the deformation of the structure by simply welding the support structure inside the top crossbeam of the outer box 5. At this time, by setting the mechanism of the present application in the inner and outer boxes 5, setting the fixing seat 1 on the inner box 6, and adjusting the height of the supporting member 3, the top crossbeam of the outer box 5 can be provided with a supporting force, thereby preventing the deformation of the upper structure of the outer box 5 and ensuring that the inner and outer box 5 devices meet the normal working requirements.

[0053] In practical applications, it can also be applied to structures without an inner box 6, for example, by placing the fixing base 1 directly on the ground and rotating the adjusting nut 41 to move the supporting member 3 in the vertical direction to support the crossbeam of the outer box 5. Of course, this supporting function is not limited to the crossbeam of the box structure, but also includes parts of the entire box that are easily deformed.

[0054] In some embodiments,

[0055] There are two sliders 2 symmetrically arranged; the supporting member 3 is mounted on the two sliders 2 ; the two sliders 2 move toward or away from each other, driving the supporting member 3 to move up or down.

[0056] Two symmetrically arranged sliders 2 are used, and the supporting member 3 is mounted on the two sliders 2. In this way, the threaded rod 4 assembly allows the supporting member 3 to move up or down when the two sliders 2 move toward or away from each other. Specifically, when the two sliders 2 move toward each other, the supporting member 3 moves upward, increasing the distance between the supporting member 3 and the fixed seat 1; when the two sliders 2 move away from each other, the supporting member 3 moves downward, reducing the distance between the supporting member 3 and the fixed seat 1.

[0057] In some embodiments,

[0058] The contact surface between the supporting member 3 and the slider 2 is set as a second inclined surface, and the second inclined surface and the first inclined surface are arranged in surface contact.

[0059] The supporting member 3 itself moves left and right and up and down along the first inclined surface. A second inclined surface is set at the position where the supporting member 3 contacts the first inclined surface. This increases the friction coefficient between the supporting member 3 and the slider 2, ensuring relative stability between the two. At the same time, the two matching first inclined surfaces and second inclined surfaces ensure that the top surface of the supporting member 3 is always in a horizontal state during the sliding process, playing a good supporting role.

[0060] In some embodiments,

[0061] There are two threaded rod 4 assemblies, which are arranged side by side on the slider 2.

[0062] The use of two threaded rod 4 component structures arranged side by side makes the applied force more uniform, ensuring that the slider 2 does not deviate during movement, thereby causing the top surface of the supporting member 3 to be non-horizontal.

[0063] In actual operation, it is best to adjust the two threaded rod 4 components synchronously. Of course, the two threaded rod 4 components can also be adjusted in steps.

[0064] In some embodiments,

[0065] A spring 42 is sleeved on the threaded rod 4 , and the spring 42 is arranged between the nut 41 and the slider 2 .

[0066] A spring 42 is sleeved on the threaded rod 4, and the elastic force of the spring 42 is used for buffering, thereby avoiding hard contact between the supporting member 3 and the part to be supported, which may cause damage to the part to be supported.

[0067] A washer is provided between the nut 41 and the spring 42. Tightening or loosening the nut 41 compresses the spring 42, which in turn generates a thrust on the slider 2, causing the slider 2 to slide. The wedge-shaped surface of the slider drives the support member 3 to move up and down, thereby achieving height adjustment.

[0068] This device can accurately control the height difference by theoretically calculating the required compression length of spring 42. When the height difference control accuracy is low, it is also possible to directly adjust the nut 41 to compress the spring 42 and push the wedge-shaped slider 2 without calculation, thereby controlling the height difference within a certain range. This application does not rely on electric drive equipment to achieve precise height adjustment and is no longer restricted by some equipment use conditions such as those that do not allow live operation.

[0069] According to another aspect of the present application, an air conditioning system is provided, comprising the air conditioner auxiliary support assembly as described above.

[0070] In some embodiments,

[0071] The air-conditioning system includes a unit and an outer box body 5, the unit is arranged in the outer box body 5; the part to be supported includes the top of the outer box body 5; the air conditioner auxiliary support assembly is arranged between the unit and the outer box body 5, the fixing seat 1 is arranged on the unit, and the supporting member 3 abuts the inner box body 6 surface at the top of the outer box body 5.

[0072] The air-conditioning system has an outer box 5 structure, and the unit is arranged in the outer box 5. At this time, the top beam of the outer box 5 is in a suspended state. For example, in the kitchen simulation device in the aircraft auxiliary cooling system device, the air conditioner 7 is arranged in the inner box 6. There is a height difference between the outer box 5 and the inner box 6. In this way, the beam of the outer box 5 may be deformed after long-term operation. A through hole is made on the fixing seat 1 of the air conditioner auxiliary support assembly and it is fixed to the inner box 6 with bolts. In this way, the supporting member 3 can support the beam of the outer box 5 to prevent it from deformation.

[0073] In some embodiments,

[0074] The air conditioning system includes a condenser shell, and the part to be supported includes the condenser shell; the air conditioner auxiliary support assembly is arranged below the condenser shell, and the supporting member 3 abuts against the outer bottom surface of the condenser shell.

[0075] For conventional evaporative cooling units, such as Figure 7 and 8 As shown, there is stress concentration at the bottom corner of the plate-fin heat exchanger (condenser), which is unfavorable to the structure; the present application sets the air conditioner auxiliary support assembly at the bottom corner of the plate-fin heat exchanger 8, as shown in FIG. Figure 5 and 6 As shown, supporting this area can overcome the stress concentration problem in this area.

[0076] The following describes the optimal structure of the air conditioner auxiliary support assembly, taking the galley simulation device used in the aircraft auxiliary cooling system as an example.

[0077] In this device with inner and outer housings 5, an air conditioner auxiliary support assembly is installed between the outer housing 5 and the inner housing 6. This air conditioner auxiliary support assembly consists of a supporting member 3, a fixing base 1, two wedge-shaped sliders 2 at a certain angle to the horizontal, two threaded rods 4, four adjusting nuts 41, four washers, four springs 42, and four sets of bolt assemblies. The angle between the supporting member 3 and the horizontal direction is the same as the angle between the wedge-shaped sliders 2 and the horizontal direction. The fixing base 1 has a sliding groove 11 on its upper surface, and the two wedge-shaped sliders 2 are nested and can slide within the sliding groove 11. The ends of the two wedge-shaped sliders 2 have through-holes, through which the two threaded rods 4 pass. Four springs 42 and four washers are nested on the two threaded rods 4. Four adjusting nuts 41 are mated with the two threaded rods 4. One end of the four springs 42 abuts against the wedge-shaped slider 2, and the other end abuts against the washers. The upper surface of the inner box 6 has corresponding mating holes, which are fixedly connected to the through holes on the bottom surface of the fixing seat 1 via a bolt assembly. By increasing the number of fixing seats 1 with completely through holes and securing them with bolt assemblies, the entire device can be adapted to accommodate devices with different height differences between the inner and outer boxes 5.

[0078] When the upper surface of the outer case 5 experiences significant deformation due to excessive size or weight, the air conditioner auxiliary support assembly is installed in the inner and outer case 5 assembly. By tightening the adjusting nuts 41 at both ends, the four springs 42 are compressed. This compression of the springs 42 exerts a horizontal thrust on the wedge-shaped slider 2. Under this horizontal thrust, the wedge-shaped slider 2 slides inward within the grooves 11 on the upper surface of the fixing base 1, thereby causing the support member 3 to move upward, offsetting the deformation of the outer case 5 upper surface and ensuring the normal operation of the inner and outer case 5 assembly. Conversely, when the adjusting nuts 41 at both ends are loosened, the wedge-shaped slider 2 slides outward within the grooves 11 on the upper surface of the fixing base 1, causing the support member 3 to move downward. Depending on the accuracy requirements of the inner and outer case 5 assembly, the adjusting nuts 41 can be adjusted coarsely to roughly control the rise and fall of the support member 3. Alternatively, the adjusting nuts 41 can be fine-tuned by calculating the required compression of the springs 42 to accurately control the rise and fall of the support member 3.

[0079] exist Figure 3Here, k is the overall stiffness of the crossbeam of the outer box 5, d is the deformation of the upper structure of the outer box 5 due to its large size or heavy weight, P1 is the pressure exerted by the outer box 5 on the support member 3 when the upper structure of the outer box 5 is not deformed and the support member 3 is in contact with the upper structure of the outer box 5. Under the action of pressure P1, the horizontal displacement of the wedge-shaped slider 2 is h1x, the elastic force of the single spring 42 is R1x, and the vertical displacement of the support member 3 is h1y. k1 is the total elastic modulus of the four springs 42, f is the friction coefficient between the support member 3 and the wedge-shaped slider, R1 is the interaction force between the support member 3 and the wedge-shaped slider 2 corresponding to the single spring 42, fR1 is the sliding friction force between the support member 3 and the wedge-shaped slider 2 corresponding to the single spring 42, and θ is the inclination angle between the inclined surface of the support member 3 and the horizontal direction.

[0080] When the upper structure of the outer box 5 does not deform and the supporting member 3 is in contact with the upper structure of the outer box 5, a force analysis is performed on the supporting member 3, and the resultant vertical force is 0:

[0081]

[0082] Take the wedge-shaped slider corresponding to a single spring as the research object, and the horizontal force is 0:

[0083]

[0084] Under the action of P1, the horizontal displacement of the wedge slider is h1x:

[0085]

[0086] The vertical displacement of the support is h1y:

[0087]

[0088] When the upper structure of the outer box body is deformed, the pressure exerted by the outer box body on the supporting member is P2. At this time, most of the force on the upper structure of the outer box body is borne by itself, and less force is transmitted to the upper surface of the supporting member. P2 is smaller than P1, and the difference is P3, then P3 = P1-P2.

[0089] When the upper structure of the outer box undergoes a large deformation and the supporting member contacts the upper structure of the outer box, a force analysis is performed on the supporting member, and the resultant vertical force is 0:

[0090]

[0091] Take the wedge-shaped slider corresponding to a single spring as the research object, and the horizontal force is 0:

[0092]

[0093] Under the action of P2, the horizontal displacement of the wedge slider is h2x:

[0094]

[0095] The vertical displacement of the support is h2y:

[0096]

[0097] The vertical displacement difference of the supporting parts when the upper structure of the outer box body has a large deformation is compared with that when it has no deformation:

[0098]

[0099] When the sliding device is not provided, the deformation of the upper structure of the outer box is d, and P3 is:

[0100]

[0101] The ratio of horizontal thrust to vertical pressure of a single spring κ:

[0102]

[0103] The sliding device moves the upper structure of the outer box from a state of large deformation to a state of no deformation, and the compression amount of the spring needs to be tightened

[0104] According to the above theoretical derivation, it can be known that: in the inner and outer box body 5 device, when the upper structure of the outer box body 5 is deformed, the overall stiffness k of the corresponding structure above the sliding device, the deformation d of the upper structure, the total elastic stiffness coefficient k1 of the spring 42, the friction coefficient f between the support member 3 and the wedge-shaped slider 2, and the inclination angle θ between the inclined direction of the support member 3 and the horizontal direction can be calculated. The pressure difference P3 exerted on the support member 3 before and after the deformation of the upper structure of the outer box body 5 can be calculated through P3 and the above parameters. The compression amount Δx of the spring 42 that needs to be tightened to change the upper structure of the outer box body 5 from a state of large deformation to a state of no deformation can be solved. The corresponding adjustment of the compression amount of the spring 42 of the auxiliary support assembly of the air conditioner can offset the deformation of the upper structure of the outer box body 5 of the inner and outer box body 5 device, so that the inner and outer box body 5 device is in a working state where the upper structure of the outer box 5 is not deformed, thereby ensuring the normal use of the inner and outer box body 5 device.

[0105] When the overall height of the sliding lifting device needs to be macroscopically changed in an inner and outer box 5 device with a large height difference, in addition to increasing the number of fixing seats 1 with completely penetrating through holes, fixing seats 1 of different heights can also be manufactured.

[0106] It is easy for those skilled in the art to understand that the above embodiments can be freely combined and superimposed on the premise that there is no conflict.

Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application. The above description is merely a preferred embodiment of the present application. It should be noted that those skilled in the art can make various improvements and variations without departing from the technical principles of the present application, and such improvements and variations shall also be considered within the scope of protection of the present application.
