Abstract
Description
Technical Field
[0001] This utility model belongs to the field of air conditioner technology, specifically relating to a heat exchanger fixing structure and an air conditioner. Background Technology
[0002] Currently, heat pump units are all equipped with shell-and-tube heat exchangers, which require external water pipes. Most units connect the water pipe joint directly to the outer panel, using a screw-outer panel-water pipe joint connection method. This causes condensation generated by the shell-and-tube heat exchanger during cooling mode to flow along the water pipes to the outer panel of the air conditioner. Over time, this will cause corrosion and rust on the outer panel, thus affecting the unit's appearance and lifespan.
[0003] During the operation of a heat pump unit, the vibration of the outer sheet metal caused by the compressor will generate noise. Directly connecting the shell-and-tube heat exchanger to the outer sheet metal will cause the force to be transmitted to the shell-and-tube heat exchanger through the water pipe. On the one hand, this will generate more noise due to resonance, and on the other hand, it may affect the operational stability of the shell-and-tube heat exchanger, thereby affecting its service life.
[0004] Because the water inlet pipe of the heat exchanger in the existing technology is connected to the air conditioner shell, the condensate water pipe on the heat exchanger will flow to the outer side panel of the air conditioner, which has technical problems such as high noise and corrosion and rust on the outer side panel. Therefore, this utility model studies and designs a heat exchanger fixing structure and an air conditioner. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0027] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.
[0028] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0029] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.
[0030] See also Figure 1-5 As shown, according to an embodiment of the present invention, a heat exchanger fixing structure is provided, including: a water receiving tray 2 and an air conditioner housing. A heat exchanger 1 is disposed on the water receiving tray 2. The heat exchanger 1 has at least two connecting pipes. The air conditioner housing has a through hole. The connecting pipes pass through the through hole and are clearance-fitted with the through hole. An mounting component is disposed on the connecting pipe. The mounting component is used to guide the condensate on the connecting pipe to the water receiving tray 2. In this technical solution, the connecting pipe is fitted with the through hole with a clearance. An mounting component is provided on the connecting pipe, which guides the condensate on the connecting pipe to the drip tray 2. The mounting component provides a fixing function for the connecting pipe, replacing the existing technology where the connecting pipe is supported by a through hole on the air conditioner housing. Vibrations from the connecting pipe cannot be transmitted to the air conditioner housing, avoiding resonance and noise between the air conditioner housing and the connecting pipe. Furthermore, the mounting component also guides the condensate on the connecting pipe, allowing it to flow into the drip tray and preventing it from flowing onto the air conditioner housing and causing corrosion and rust. It should be noted that in the heat exchanger fixing structure of this utility model, the connecting pipe refers to the inlet and outlet pipes of the heat exchanger 1, and the air conditioner housing refers to the sheet metal parts of the air conditioner.
[0031] Shell-and-tube heat exchangers require external water pipes. Current technology connects the water pipe connector directly to the outer side panel using a screw-outer side panel-water pipe connector connection method. This installation method is the most economical, requiring only mounting holes for the shell-and-tube water pipe connector to be designed into the external sheet metal parts, without adding any additional parts. However, this leads to condensation leakage. Specifically, condensation generated by the shell-and-tube heat exchanger during cooling operation flows along the water pipe to the outer side panel of the air conditioner. Over time, this will cause corrosion and rust on the outer side panel, affecting the unit's appearance and lifespan.
[0032] In some embodiments, the connecting pipe includes a first water pipe 3 and a second water pipe 4, and the mounting component includes a first bracket 5 and a second bracket 6. The first water pipe 3 and the second water pipe 4 pass through the through hole, and the first water pipe 3 and the second water pipe 4 are clearance-fitted with the through hole. The first water pipe 3 is connected to the water receiving tray 2 through the second bracket 6, and the second water pipe 4 is connected to the air conditioner housing through the first bracket 5. In this technical solution, the first water pipe 3 and the second water pipe 4 are the inlet pipe and outlet pipe of the heat exchanger 1, respectively. Since the inlet pipe and the outlet pipe of the heat exchanger 1 have different heights, in order to save space inside the air conditioner housing, the height of the second water pipe 4 is higher than the height of the first water pipe 3. Therefore, the first water pipe 3 is connected to the water receiving tray 2 through the second bracket 6, and the second water pipe 4 is connected to the air conditioner housing through the first bracket 5. This eliminates the need for excessive mounting support structures on the water receiving tray 2, ensuring the drainage efficiency of the water receiving tray 2 and draining water from higher locations. The second water pipe 4 is installed on the air conditioner housing, that is, on the side wall of the air conditioner housing. Since the distance between the second water pipe 4 and the side wall of the air conditioner housing is small, it avoids the need for a high bracket to fix the second water pipe, which would affect the stability of the water pipe. Secondly, since the first water pipe 3 and the second water pipe 4 are fitted with the through hole with a clearance, the vibration of the first water pipe 3 and the second water pipe 4 cannot be transmitted to the air conditioner housing, which further reduces the noise of the air conditioner housing. The first bracket 5 and the second bracket 6 can also absorb some of the vibration on the second water pipe 4 and the first water pipe 3, further reducing the noise of the air conditioner.
[0033] In some embodiments, the second bracket 6 and the first bracket 5 are arranged close to the air conditioner casing relative to the heat exchanger 1. With the drip tray 2 as the projection surface, the second bracket 6 and the first bracket 5 are located within the drip tray. The second water pipe 4 is snapped or sleeved with the first bracket 5, and the first water pipe 3 is snapped or sleeved with the second bracket 6. In this technical solution, by using the drip tray 2 as the projection surface and positioning the second bracket 6 and the first bracket 5 within the drip tray 2, the condensate on the second bracket 6 and the first bracket 5 falls into the drip tray 2 under the action of gravity, thereby discharging the condensate outside the air conditioner.
[0034] In some embodiments, the second water pipe 4 is snapped into the first bracket 5, and the first water pipe 3 is snapped into the second bracket 6. Grooves or other snapping structures can be provided on the first bracket 5 and the second bracket 6. The water pipe is installed on the bracket by snapping, thereby supporting the water pipe and guiding the condensate on the water pipe.
[0035] In some embodiments, the second water pipe 4 is sleeved with the first bracket 5, and the first water pipe 3 is sleeved with the second bracket 6. That is, through holes can be provided on the first bracket 5 and the second bracket 6. The water pipe is interference-fitted with the through hole to support the water pipe and guide the condensate on the water pipe.
[0036] This utility model's heat exchanger fixing structure includes a first bracket 5 and a second bracket 6 inside the air conditioning unit to prevent condensate from flowing out. The water receiving tray 2 below the shell-and-tube heat exchanger 1 has a stable drainage structure to ensure timely and effective drainage of condensate. This reduces noise caused by direct connection between the shell-and-tube heat exchanger and the external sheet metal parts, ensuring the operational stability and reliability of the shell-and-tube heat exchanger. It solves the problem of condensate leakage caused by water pipe fixing, ensuring that the unit's external sheet metal will not corrode or rust. It ensures timely drainage of condensate, preventing refrigerant pipes from freezing due to condensate accumulation.
[0037] This utility model's heat exchanger fixing structure eliminates direct contact between the shell-and-tube heat exchanger and the outer sheet metal parts, effectively reducing shell-and-tube swaying caused by vibration of the outer sheet metal parts and optimizing noise. A first bracket 5 and a second bracket 6 are designed inside the heat pump unit to directly guide condensate to the water receiving tray 2 above the unit, and discharge it outside the unit through the drain port 14 on the water receiving tray 2, preventing condensate from flowing out through the outer sheet metal parts. The first bracket 5 and the second bracket 6 eliminate direct contact between the shell-and-tube heat exchanger 1 and the outer sheet metal parts, eliminating resonance between them, effectively reducing noise caused by vibration of the outer sheet metal parts during unit operation, and ensuring the operational stability and service life of the shell-and-tube heat exchanger.
[0038] In some embodiments, the second bracket 6 has an L-shaped structure, and there is a first gap between the second bracket 6 and the air conditioner housing. The second bracket 6 has a first side and a second side connected in sequence. A first notch 16 is provided at the end of the first side facing away from the second side. The second side is connected to the water receiving tray 2. The first water pipe 3 is snapped into the first notch 16, and the opening of the first notch 16 faces away from the second side. In this technical solution, the first water pipe 3 is snapped into the second bracket 6 through the first notch 16. The L-shaped structure of the second bracket 6 facilitates the fixing of the water pipe and the installation of the bracket. Specifically, multiple connecting holes can be provided on the second side, through which the second bracket 6 and the water receiving tray 2 are screwed together. When a connector 8 is provided on the first water pipe 3, multiple connecting holes can also be provided on the first side to fix the bracket to the connector 8.
[0039] In some embodiments, the first bracket 5 has an L-shaped structure, a second gap between the first bracket 5 and the air conditioner housing, a second notch 15 on the first bracket 5, and the second water pipe 4 is engaged with the second notch 15. The first bracket 5 is connected to the air conditioner housing via a third bracket 7. In this technical solution, the second water pipe 4 is engaged with the first bracket 5 via the second notch 15. The L-shaped structure of the first bracket 5 facilitates the fixing of the water pipe and the installation of the bracket. Preferably, since the second water pipe 4 is relatively high, in order to improve the support strength of the second water pipe 3, the first bracket 5 can be arranged along the axial direction of the second water pipe 4, and then connected to the first bracket 5 via the third bracket 7, thereby fixing the first bracket 5 inside the air conditioner housing.
[0040] In some embodiments, the first support 5 includes a first segment 9, a second segment 10, a third segment 11, and a fourth segment 12, which are connected sequentially. The first segment 9 and the second segment 10 form an angle, and the third segment 11 and the fourth segment 12 form an angle. The second segment 10 and the fourth segment 12 extend in the same direction. The first segment 9 and the third segment 11 are parallel. The second notch 15 is located on the second segment 10, the third segment 11, and the fourth segment 12, and the opening of the second notch 15 is located on the fourth segment 12. In this technical solution, the first segment 9 and the second segment 10 form an angle, and the third segment 11 and the fourth segment 12 also form an angle. Furthermore, the second segment 10 and the fourth segment 12 extend in the same direction, the first segment 9 and the third segment 11 are parallel, and the second notch 15 is located on the second segment 10, the third segment 11, and the fourth segment 12. The opening of the second notch 15 is located on the fourth segment 12, creating a two-stage stepped structure between the first segment 9, the second segment 10, the third segment 11, and the fourth segment 12. Multiple connection holes can be provided on the second segment 10 and the fourth segment 12. When a connector 8 is installed on the second water pipe 4, the bracket is fixed to the connector 8 through the connection holes. Moreover, the structure between the second segment 10, the third segment 11, and the fourth segment 12 further ensures the gap between the first bracket 5 and the air conditioner housing, facilitating the installation of the first bracket 5 and preventing collisions between the first bracket 5 and the air conditioner housing 5.
[0041] In some embodiments, the first bracket 5 further includes a fifth segment 13, which is located on the side of the first segment 9 facing away from the second segment 10. The fifth segment 13 is connected to the first segment 9, and there is an angle between the fifth segment 13 and the first segment 9. The extension direction of the fifth segment 13 is opposite to that of the second segment 10. The fifth segment 13 is also connected to the third bracket 7. In this technical solution, to facilitate the installation of the third bracket 7, the fifth segment 13 is located on the side of the first segment 9 facing away from the second segment 10, and is connected to the first segment 9. The fifth segment 13 is at an angle to the first segment 9, and the extension direction of the fifth segment 13 is opposite to that of the second segment 10. This makes the installation of the third bracket 7 and the first bracket 5 more convenient without affecting the first water pipe 5.
[0042] In some embodiments, a vibration damping element is provided between the connecting pipe and the mounting component, and the vibration damping element is sleeved on the connecting pipe; the through hole is an oblique hole, with the direction of the water receiving tray 2 towards the heat exchanger 1 as the height direction, and the height of the end of the through hole facing the heat exchanger 1 is less than the height of the other end of the through hole. In this technical solution, by providing a vibration damping element between the connecting pipe and the mounting component, and the vibration damping element being sleeved on the connecting pipe, the vibration damping element can be made of rubber. By providing a vibration damping element between the mounting component and the connecting pipe, the vibration of the connecting pipe can be further reduced, thereby reducing the noise of the air conditioner. The through hole is an oblique hole, with the direction of the water receiving tray 2 towards the heat exchanger 1 as the height direction, and the height of the end of the through hole facing the heat exchanger 1 is less than the height of the other end of the through hole. In other words, the through hole is an upward-sloping hole. This means that the connecting pipe will also be installed at an angle. After the connecting pipe is installed, the condensate on the connecting pipe will flow along the connecting pipe to the heat exchanger, further improving the heat exchange efficiency of the heat exchanger. In addition, the condensate on the connecting pipe will fall from the heat exchanger 1 onto the drip tray 2, ensuring that the condensate on the connecting pipe will not affect the air conditioner casing or other components inside the air conditioner.
[0043] In some embodiments, a connector 8 is provided at the end of the connecting pipe facing away from the heat exchanger 1. The connector 8 is at least partially located in the through hole. The mounting component is connected to the connector 8. With the ground as the horizontal plane, the height of the side of the water receiving tray 2 facing away from the connector 8 is greater than the height of the other side of the water receiving tray 2. A drain outlet 14 is provided on the water receiving tray 2, and the drain outlet 14 is arranged near the other side of the water receiving tray 2. In this technical solution, a connector 8 is provided at the end of the connecting pipe facing away from the heat exchanger 1. The connector 8 is at least partially located inside the through hole. The mounting component is connected to the connector 8, and the connecting pipe is connected to the external pipeline through the connector 8. Since the outer diameter of the connector 8 is larger than the outer diameter of the connecting pipe, that is, the installation area of the connector 8 is large, which facilitates the installation of the mounting component. The height of the side of the water receiving tray 2 facing away from the connector 8 is greater than the height of the other side of the water receiving tray 2. A drain outlet 14 is provided on the water receiving tray 2. The drain outlet 14 is arranged close to the other side of the water receiving tray 2. This arrangement of the water receiving tray 2 allows the condensate on the water receiving tray 2 to collect quickly and be discharged from the drain outlet 14 to the outside of the air conditioner, avoiding the formation of water accumulation on the water receiving tray 2, which would affect the air conditioner.
[0044] The heat exchanger fixing structure of this utility model features a stable drainage structure in the water receiving tray 2 below the shell-and-tube heat exchanger 1, ensuring timely and effective discharge of condensate. The water receiving tray 2 is designed below the shell-and-tube heat exchanger 1, with mounting holes for connection via bolts and nuts. The shell-and-tube heat exchanger 2 is externally connected to inlet and outlet water pipes. Separate mounting components are designed at the water pipe joints 8 of the inlet and outlet pipes. These components serve two purposes: firstly, to secure the inlet and outlet pipe joints 8, facilitating pipe installation; and secondly, to guide condensate into the water receiving tray 2 below, from where it is discharged through the drain outlet 14. The first bracket 5 and the second bracket 6 are for fixing the shell-and-tube water pipe joints. The first bracket 5 is connected to the water receiving tray via a third bracket 7 using screws. Similarly, the first bracket 5 is connected to the air conditioner housing via the third bracket 7 using screws. The second bracket 6 is directly fixed to the water receiving tray 2.
[0045] See also Figure 3 and Figure 4 As shown, the first bracket 5 and the second bracket 6 have notches, i.e., U-shaped grooves. The U-shaped grooves and screw holes on both sides are used for the installation and fixing of water pipe joints. The outer part of the U-shaped groove acts as a water barrier, preventing condensation from flowing out of the water pipe and guiding it to the drip tray 2 below. The first bracket 5 and the second bracket 6 are made of passivated sheet metal material to prevent rusting due to long-term contact with condensation. A certain gap is maintained between the brackets and the outer sheet metal parts to ensure that all condensation is guided through the sheet metal parts to the drip tray below, and does not seep onto the outer sheet metal parts, causing corrosion and rust.
[0046] The notches of the first bracket 5 and the second bracket 6 are installed with different orientations. The first bracket 5 extends from the third bracket 7 supporting the top cover, using a horizontal notch to fix the water pipe connector 8. This saves space by reducing the space required for additional brackets on the drip tray and avoids designing a tall bracket to fix the water pipe, which could affect the stability of the water pipe connector. The first bracket 5 has a stepped structure with mounting holes on both stepped planes. The mounting holes on the second section 10 are used to fix the water pipe connector 8, while the mounting holes on the fourth section 12 can overcome the gap between the bracket and the outer sheet metal, allowing the first bracket 5 to be fixed to the outer sheet metal with screws, further ensuring the stability of the water pipe fixation.
[0047] Compared to the traditional screw-outer plate-water pipe connector connection method, the heat exchanger fixing structure of this utility model adopts a screw-water pipe connector-bracket connection method, which separately fixes the water pipe connector to the bracket. This completely eliminates the contact between the outer sheet metal parts and the shell-and-tube heat exchanger, preventing the force generated by the vibration of the outer sheet metal parts during transportation and use from being transmitted to the shell-and-tube heat exchanger. This design ensures the stability and reliability of the shell-and-tube heat exchanger operation and extends the service life of the shell.
[0048] The water collection tray 2 needs to maintain a 1-2° tilt angle, with the left side higher than the right, to ensure that condensate can accurately and quickly collect and drain from the drain outlet 14 on the left side of the tray. In addition to drain outlet 14, other openings are provided on the water collection tray 2 for pipe routing. These other openings utilize bosses and flanged holes to prevent condensate from flowing into the unit through these openings. Drain outlet 14 features a recessed design, meaning the plane of the area where drain outlet 14 is located is concave downwards, ensuring that condensate can quickly collect and drain. A specific drain pipe connects below drain outlet 14, guiding the condensate to the chassis below the unit, where it is drained through the drain outlet on the chassis.
[0049] This utility model also provides an air conditioner, including the heat exchanger fixing structure described above.
[0050] It will be readily understood by those skilled in the art that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

The above description is only a preferred embodiment of this utility model.
