Description

Combined heat exchanger and air conditioner Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to a combined heat exchange device and air conditioner. Background Technology

[0002] To improve the heat exchange efficiency of heat exchange devices, these devices are gradually becoming larger in size. However, large-volume heat exchange devices are difficult to manufacture directly, so they are often combined by connecting smaller heat exchangers to form modular heat exchange devices, thereby improving the heat exchange efficiency.

[0003] Because modular heat exchangers are large and difficult to transport, the components often need to be transported separately to the operating environment before being assembled into a modular unit. Furthermore, transporting the components separately to the assembly site requires repositioning the interconnected heat exchangers, significantly reducing assembly efficiency at the assembly site. Summary of the Invention

[0004] This utility model provides a combined heat exchange device and an air conditioner to reduce the installation difficulty of the combined heat exchange device.

[0005] In a first aspect, this utility model provides a combined heat exchange device, comprising:

[0006] First heat exchanger; and

[0007] The second heat exchanger is connected to the first heat exchanger via a connecting mechanism;

[0008] The connecting mechanism includes a first connecting component connected to the first heat exchanger and a second connecting component connected to the second heat exchanger. The first connecting component and the second connecting component are rotatably connected to adjust the assembly angle between the first heat exchanger and the second heat exchanger.

[0009] At least one of the first connecting component and the second connecting component has multiple clamping angles to adapt to the corresponding heat exchanger.

[0010] In one embodiment, the first heat exchanger includes a first portion and a second portion arranged at an angle, and the first connecting assembly includes a first clamping member for clamping the first portion and a second clamping member for clamping the second portion, the first clamping member and the second clamping member being rotatably connected to accommodate the angle between the first portion and the second portion.

[0011] In one embodiment, the first clamping member and the second clamping member are rotatably connected via a second hinge axis.

[0012] In one embodiment, the first clamping member is made of sheet metal and has a clamping groove, wherein the first portion is inserted into the clamping groove and is interference-fitted with the first clamping member.

[0013] In one embodiment, the second heat exchanger includes a third portion and a fourth portion arranged at an angle, and the second connecting assembly includes a third clamping member for clamping the third portion and a fourth clamping member for clamping the fourth portion, the third clamping member and the fourth clamping member being rotatably connected to accommodate the angle between the third portion and the fourth portion.

[0014] In one embodiment, the assembly angle between the first heat exchanger and the second heat exchanger includes at least a first angle and a second angle;

[0015] At the first angle, the first heat exchanger and the second heat exchanger overlap along a first direction, which is the thickness direction of the first heat exchanger;

[0016] At the second angle, the first heat exchanger and the second heat exchanger overlap along the second direction, which is the length direction of the first heat exchanger;

[0017] Wherein, the length of the first heat exchanger in the first direction is less than the length of the first heat exchanger in the second direction.

[0018] In one embodiment, at the second angle, the two end faces of the first heat exchanger in the second direction are respectively aligned with the two end faces of the second heat exchanger in the second direction.

[0019] In one embodiment, the first connecting component includes a first locking element, and the second connecting component includes a second locking element;

[0020] At the first angle, the first locking member cooperates with the second locking member to lock the included angle between the first heat exchanger and the second heat exchanger.

[0021] In one embodiment, one of the first locking member and the second locking member is a snap-fit ​​structure and the other is a slot structure. At a first angle, the first locking member and the second locking member are engaged and locked.

[0022] Secondly, this utility model also provides an air conditioner, which includes: the above-mentioned combined heat exchange device.

[0023] Compared with existing technologies, the advantages of this invention are as follows: Since the first and second heat exchangers are rotatably connected via a connecting mechanism, the transportation difficulty of the combined heat exchange device can be reduced by adjusting the angle between the first and second connecting components during transport, while ensuring that the first and second heat exchange components remain connected during transportation. At the assembly site, the assembly angle between the first and second heat exchangers can be adjusted by rotation, significantly reducing the difficulty of positioning. Furthermore, since at least one of the first and second connecting components has multiple clamping angles, it can adapt to heat exchangers of different shapes, reducing the types of connecting mechanisms and lowering manufacturing costs.

[0046] The present invention will be further described below with reference to the accompanying drawings.

[0047] Referring to Figures 1 to 3, this application provides a combined heat exchange device, which includes a first heat exchanger 100, a second heat exchanger 200, and a connecting mechanism 300 that rotatably connects the first heat exchanger and the second heat exchanger 200.

[0048] The connecting mechanism 300 includes a first connecting component 310 connected to the first heat exchanger 100 and a second connecting component 320 connected to the second heat exchanger 200. The first connecting component 310 and the second connecting component 320 are rotatably connected, and the assembly angle between the first heat exchanger 100 and the second heat exchanger 200 can be adjusted by rotating about the axis of rotation of the first connecting component 310 and the second connecting component 320.

[0049] During transportation, the assembly angle between the first heat exchanger 100 and the second heat exchanger 200 can be adjusted to an acute angle, thereby reducing the transportation difficulty of the combined heat exchange device and ensuring that the first heat exchanger 100 and the second heat exchanger 200 remain connected during transportation. After transportation to the assembly site, the assembly angle between the first heat exchanger 100 and the second heat exchanger 200 can be adjusted to the operating angle by rotation. Compared to positioning and connecting two separate heat exchangers, the pre-positioning of the two heat exchangers can be achieved through the connecting mechanism 300, thereby reducing the positioning difficulty at the assembly site and improving the assembly efficiency at the assembly site.

[0050] It should be noted that the first heat exchanger 100 and the second heat exchanger 200 can both be condensers, or one of the first heat exchanger 100 and the second heat exchanger 200 can be set as a condenser and the other as an evaporator, or both can be set as evaporators.

[0051] This embodiment provides a combined heat exchange device with two heat exchangers. In some implementations, the combined heat exchange device may also include a third heat exchanger, and another connecting mechanism 300 is provided at the end of the second heat exchanger 200 away from the first heat exchanger 100, through which the second heat exchanger 200 and the third heat exchanger are rotatably connected. During transportation, the three heat exchangers can be folded to reduce the difficulty of transporting the combined heat exchange device. When transferred to the application scenario, the three heat exchangers can be unfolded, so that the first heat exchanger 100 is locked to the second heat exchanger 200, and the second heat exchanger 200 is locked to the third heat exchanger.

[0052] It is understandable that a combined heat exchanger can also be a combination of four or five heat exchangers. Rotational connections between adjacent heat exchangers are achieved through multiple connecting mechanisms 300.

[0053] Referring to Figures 1 to 4, in some implementations, the first connecting component 310 and the second connecting component 320 are connected by a first hinge shaft 330, making the included angle between the first connecting component 310 and the second connecting component 320 adjustable. In practical use, a rotational connection between the first connecting component 310 and the second connecting component 320 can also be achieved through other structures.

[0054] Referring to Figures 1 and 2, some radiators have bent ends. Previously, when adapting similar heat exchanger structures, it was necessary to manufacture connection structures with corresponding angles for heat exchangers with different clamping angles, significantly increasing material costs. In this application, by configuring at least one of the first connecting component 310 and the second connecting component 320 to have multiple clamping angles to adapt to corresponding heat exchangers, it is possible to use a single connecting component to adapt to heat exchangers of various sizes, reducing material costs.

[0055] In this case, it is possible that only the first connecting component 310 has multiple clamping angles, while the second connecting component 320 has a single clamping angle; it is also possible that the second connecting component 320 has multiple clamping angles, while the first connecting component 310 has a single clamping angle; or as shown in Figure 3 or Figure 4, both the first connecting component 310 and the second connecting component 320 are configured to have multiple clamping angles.

[0056] Referring to Figures 1 and 2, in some implementations, the first heat exchanger 100 includes a first portion 110 and a second portion 120 arranged at an angle. The first connecting assembly 310 includes a first clamping member 311 for clamping the first portion 110 and a second clamping member 312 for clamping the second portion 120 (the structure of which can be seen in Figures 8 to 10). The first clamping member 311 and the second clamping member 312 are rotatably connected to accommodate the angle between the first portion 110 and the second portion 120. In some implementations, the first clamping member 311 and the third clamping member 321 have a mirror-symmetrical structure.

[0057] Since the included angle between the first part 110 and the second part 120 in different first heat exchangers 100 may vary, in this application, a first clamping member 311 and a second clamping member 312, which are rotatably connected, are respectively used to connect to the first part 110 and the second part 120. This allows the first connecting assembly 310 to adapt to first heat exchangers 100 with different included angles, reducing the types of first connecting assemblies 310 and lowering material costs.

[0058] Because there is an angle between the first part 110 and the second part 120, by clamping the first part 110 with the first clamping member 311 and the second part 120 with the second clamping member 312, the bending of the first heat exchanger 100 can be used to position the first connecting component, thus avoiding relative misalignment between the first clamping member 311 and the second clamping member 312 during use and improving the positioning accuracy of the first connecting component. This also avoids installation errors between the first heat exchanger 100 and the second heat exchanger 200 caused by installation errors of the first connecting component, reducing the difficulty of positioning the first heat exchanger 100 and the second heat exchanger 200 on-site and improving the assembly efficiency of the combined heat exchange device.

[0059] In some implementations, the angle between the first clamping member 311 and the second clamping member 312 is adjustable within the range of [-60°, 180°] to accommodate first heat exchangers 100 of various shapes.

[0060] Referring to Figures 3 and 4, in some implementations, the first clamping member 311 and the second clamping member 312 are rotatably connected via a second hinge shaft 314. Both the ends of the first clamping member 311 and the second clamping member 312 have hinged flanges, and these flanges can engage with the hinged flanges of the second clamping member 312 to form the second hinge shaft 314 structure, thus achieving a hinged connection between the first clamping member 311 and the second clamping member 312. Specifically, the hinged flanges of the first clamping member 311 form a shaft structure, while the second clamping member 312 has two spaced-apart hinged flanges, each forming a hole structure. By inserting the hinged flange of the first clamping member 311 into the two holes formed by the hinged flange of the second clamping member 312, the hinged connection between the first clamping member 311 and the second clamping member 312 can be achieved. It is understandable that the hinged connection between the first clamping member 311 and the second clamping member 312 can also be achieved directly using an existing hinged structure.

[0061] In some implementations, the first clamping member 311 is made of sheet metal and has a clamping groove. The first portion 110 is inserted into the clamping groove and has an interference fit with the first clamping member 311. That is, in this application, the first clamping member 311 is connected to the first portion 110 by clamping. Due to the interference fit between the first clamping member 311 and the first portion 110, the connection strength between the first clamping member 311 and the first portion 110 is improved, and separation of the first clamping member 311 and the first portion 110 is prevented.

[0062] It is understandable that, in order to improve the connection strength between the first clamping member 311 and the first part 110, a through hole can be opened on the first clamping member 311 and a threaded hole can be provided at the corresponding position of the first part 110. After the locking screw passes through the through hole on the first clamping member 311, it is threaded into the threaded hole of the first part 110, thus ensuring a reliable connection between the first clamping member 311 and the first part 110.

[0063] Alternatively, the first clamping member 311 can be directly welded to the first part 110 to improve the reliability of the connection between the first part 110 and the first clamping member 311.

[0064] Referring to Figures 5 to 7, the corresponding second clamping member 312 can also be made of sheet metal, and a clamping groove for the second part 120 to be inserted is formed through the second clamping member 312, so that the second part 120 is inserted into the second clamping member 312, thus completing the interference fit between the second clamping member 312 and the second part 120.

[0065] In some implementations, a reinforcing rib 340 is provided on the outer side of the first clamping member 311. By providing a reinforcing rib 340 on the outer side of the first clamping member 311, deformation of the two side plates of the first clamping member 311 can be avoided, thereby maintaining the shape of the clamping groove of the first clamping member 311 and ensuring the interference fit between the first clamping member 311 and the first part 110.

[0066] Referring to Figures 1 and 2, the second heat exchanger 200 includes a third part 210 and a fourth part 220 arranged at an angle. The second connecting assembly 320 includes a third clamping member 321 for clamping the third part 210 (the structure of which can be seen in Figures 6 to 8) and a fourth clamping member 322 for clamping the fourth part 220 (the structure of which can be seen in Figures 11 to 13). The third clamping member 321 and the fourth clamping member 322 are rotatably connected to accommodate the angle between the third part 210 and the fourth part 220.

[0067] In other words, by rotating the third clamping member 321 and the fourth clamping member 322, the second component can be adapted to the second heat exchanger 200 with different bending angles, reducing the types of second components and lowering the material cost of the combined heat exchange device.

[0068] In some implementations, the third clamping member 321 and the fourth clamping member 322 are rotatably connected by a third hinge shaft 324. The third hinge shaft 324 can be formed by the fitting of the folded edge of the third clamping member 321 and the folded edge of the fourth clamping member 322.

[0069] Referring to Figure 5, in some implementations, the outer side of the third clamping member 321 is also provided with reinforcing ribs 340 to improve the strength of the third clamping member 321 and ensure the interference fit between the third clamping member 321 and the second heat exchanger 200.

[0070] Understandably, the first connecting assembly 310 and the second connecting assembly 320 can also be made of plastic. Compared to sheet metal parts, plastic parts are less expensive and can be formed into more complex shapes for better connection with the heat exchanger.

[0071] Referring to Figures 1 and 2, the assembly angle between the first heat exchanger and the second heat exchanger includes at least a first angle and a second angle.

[0072] At the second angle, the first heat exchanger 100 and the second heat exchanger 200 overlap along the first direction, which is the thickness direction of the first heat exchanger 100; at the first angle, the first heat exchanger 100 and the second heat exchanger 200 overlap along the second direction, which is the length direction of the first heat exchanger 100, wherein the length of the first heat exchanger 100 in the first direction is less than the length of the first heat exchanger 100 in the second direction.

[0073] In other words, when transporting the combined heat exchanger, the overall length of the combined heat exchanger can be shortened and the transportation difficulty reduced by adjusting it to the second angle so that the first heat exchanger 100 and the second heat exchanger 200 overlap along the thickness direction of the first heat exchanger 100. However, when using or assembling the combined heat exchanger, it needs to be adjusted to the first angle so that the first heat exchanger 100 and the second heat exchanger 200 overlap along the length direction of the first heat exchanger 100, increasing the contact area between the combined heat exchanger and the air, and improving the heat exchange rate between the combined heat exchanger and the air.

[0074] Because the length of the first heat exchanger 100 in the first direction is less than the length of the first heat exchanger 100 in the second direction, when the first heat exchanger 100 and the second heat exchanger 200 are arranged to overlap along the first direction, the second heat exchanger 200 will overlap with the large surface area of ​​the first heat exchanger 100, thereby lowering the center of gravity of the combined heat exchange device and making it more stable during transportation.

[0075] To achieve the above effects, in this application, the first connecting component 310 of the connecting mechanism 300 is connected to the upper end of the first heat exchanger 100 (in the assembled state), and the second connecting component 320 of the connecting mechanism 300 is connected to the lower end of the second heat exchanger 200 (in the assembled state). At the second angle, the upper end of the second heat exchanger 200 rotates around the connecting mechanism 300 to face downwards and is located below the upper end of the second heat exchanger 200. This causes the first heat exchanger 100 and the second heat exchanger 200 to overlap along the thickness direction of the first heat exchanger 100, lowering the center of gravity of the combined heat exchange device and reducing the transportation difficulty of the combined heat exchange device. At the first angle, the upper end of the second heat exchanger 200 rotates around the connecting mechanism 300 to face upwards and is located at the top of the second heat exchanger 200, causing the first heat exchanger 100 and the second heat exchanger 200 to overlap along the length direction of the first heat exchanger 100, increasing the contact area between the combined heat exchange device and the external environment.

[0076] Referring to Figure 2, in some implementations, at the second angle, the two end faces of the first heat exchanger 100 in the second direction are respectively flush with the two end faces of the second heat exchanger 200 in the second direction. That is, at the second angle, the top surface of the first heat exchanger 100 is flush with the top surface of the second heat exchanger 200, and the bottom surface of the first heat exchanger 100 is flush with the bottom surface of the second heat exchanger 200. This minimizes the space occupied by the combined heat exchange device and reduces unnecessary space waste.

[0077] Figure 1 shows the structure of the combined heat exchanger at the first angle, while Figure 2 shows the structure at the second angle. It can be seen that the combined heat exchanger is quite tall at the first angle, occupying a large space and increasing its center of gravity, making transportation very difficult. Adjusting the combined heat exchanger to the second angle reduces its height and lowers its center of gravity, making transportation much easier.

[0078] When using the combined heat exchange device provided in this application, the angle between the first heat exchanger 100 and the second heat exchanger 200 can be adjusted to the second angle to reduce the transportation difficulty of the combined heat exchange device and prevent the two heat exchangers of the combined heat exchange device from separating during transportation.

[0079] Referring to Figures 3 and 4, the first connecting assembly 310 includes a first locking member 313; the second connecting assembly 320 is connected to the second heat exchanger 200, and the second connecting assembly 320 includes a second locking member 323, wherein the first locking member 313 and the second locking member 323 are locked together at a first angle.

[0080] When the combined heat exchanger is transported to the site of use, the angle between the first heat exchanger 100 and the second heat exchanger 200 can be locked by rotating the combined heat exchanger to the first angle, which prevents relative rotation between the first heat exchanger 100 and the second heat exchanger 200 during use and ensures the stability of the combined heat exchanger during use.

[0081] Because of the connection structure that links the two heat exchangers, separation during transportation is prevented, thus avoiding the need for on-site matching and saving installation time. Furthermore, the ability to lock the first heat exchanger 100 and the second heat exchanger 200 by rotation significantly reduces installation difficulty for personnel compared to conventional positioning installations, further saving on-site installation time.

[0082] Referring to Figures 3 and 4, the first locking member 313 and the second locking member 323 can be locked by a snap-fit ​​mechanism. For example, the second locking member 323 can be provided with a snap-fit ​​structure, and the corresponding first locking member 313 can be provided with a slot structure. When rotated to the first angle, the included angle between the first connecting component 310 and the second connecting component 320 decreases, so that the snap-fit ​​of the second locking member 323 can be directly inserted into the slot of the first locking member 313. The anti-disengagement protrusion on the second locking member 323 prevents the first connecting component 310 and the second connecting component 320 from rotating relative to each other. Compared with other locking structures, the snap-fit ​​locking structure is simpler.

[0083] Referring to Figures 3 and 4, the first connecting assembly 310 has two spaced-apart first locking members 313, and the second connecting assembly 320 has two spaced-apart second locking members 323. When locked, each first locking member 313 engages with its corresponding second locking member 323 to achieve a locking effect. Compared to locking with a single first locking member 313, the locking force of two first locking members 313 is stronger, better preventing the first heat exchanger 100 from rotating relative to the second heat exchanger 200.

[0084] It is understandable that the second locking member 323 can also be configured as a slot structure, and the first locking member 313 can be configured as a snap-fit ​​structure. To prevent the locking members from disengaging after locking, the first locking member 313 and the second locking member 323 can be made of spring steel. This would give the first locking member 313 and the second locking member 323 a certain degree of elasticity, so that when the anti-disengagement protrusion of the first locking member 313 is inserted into the slot of the second locking member 323, it can spring back, allowing the anti-disengagement protrusion to insert into the limiting groove of the slot structure.

[0085] In some implementations, the first locking member 313 and the second locking member 323 can be manually unlocked to meet the requirements for re-transportation. For example, for the first locking member 313 and the second locking member 323 that engage in a snap-fit ​​configuration, after locking, the snap-fit ​​structure can be removed from the slot structure by squeezing the anti-detachment protrusion in the anti-detachment groove, thus completing the unlocking process.

[0086] The first locking member 313 can be disposed on the first clamping member 311 or the second clamping member 312 (as shown in Figure 3 or Figure 4), or the first locking member 313 can be disposed on both the first clamping member 311 and the second clamping member 312. Similarly, the second locking member 323 can be disposed on the third clamping member 321 or the fourth clamping member 322, or the second locking member can be disposed on both the third clamping member 321 and the fourth clamping member 322.

[0087] Secondly, this utility model also provides an air conditioner, which includes the aforementioned combined heat exchange device. Because the combined heat exchange device connects two heat exchangers via a connecting mechanism 300, it avoids separation or misalignment of the heat exchangers during transportation, eliminating the need to locate the corresponding heat exchangers during installation. Furthermore, since the connecting structure allows for angle adjustment between the two heat exchangers, the unfolded combined heat exchange device can be easily deployed during transportation.

[0088] The adjustable angle significantly reduces the transportation difficulty of the combined heat exchange device. Furthermore, when the combined heat exchange device is adjusted to the first angle, the connecting mechanism 300 can be used to position the first heat exchanger 100 and the second heat exchanger 200, eliminating the need for manual positioning of the two heat exchangers and reducing the assembly difficulty when assembling the air conditioner.

[0089] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict.
