Description

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to a pipe clamp, a heat exchanger and an air conditioner. Background Technology

[0002] In the field of air conditioner outdoor units, heat exchangers are one of the most basic components. By stacking multiple rows of heat exchange coils, the heat exchange performance is improved, thereby achieving a higher cooling capacity. During the stacking and assembly of multiple rows of heat exchangers, in order to ensure the stability of the structure, the heat exchangers need to be connected and fixed at the tube end.

[0003] There are two common methods. One is to fix the heat exchanger end plate sheet metal with screws. This method is complicated and involves screwing in multiple locations. Operators are at risk of damaging the copper tubes. In addition, for heat exchangers of different specifications, the connection plate structure with corresponding connection holes needs to be designed accordingly. The connection method is relatively complicated and the connection efficiency is low. Utility Model Content

[0004] The main objective of this utility model embodiment is to provide a pipe clamp, heat exchanger, and air conditioner, which aims to improve the technical problem of low connection efficiency in the existing multi-row heat exchange tube stacking connection method.

[0005] An embodiment of this utility model provides a pipe clamp, which includes:

[0006] First plate;

[0007] The second plate has one end connected to one end of the first plate, and the other end of the second plate is detachably connected to the other end of the first plate. When the two ends of the second plate are respectively connected to the two ends of the first plate, the first plate and the second plate are connected to form a ring structure.

[0008] The first plate has at least one deformable part, which is configured to bend toward the inner cavity of the annular structure and be fixed after bending to form a partition structure to divide the inner cavity of the annular structure.

[0009] In some embodiments of this utility model, the deformable part has a guide part that protrudes toward the inner cavity of the annular structure. The deformable part is configured to gradually bend as the guide part moves toward the inner cavity of the annular structure and to be fixed to form the partition structure as the guide part stops moving.

[0010] In some embodiments of this utility model, the deformable part includes a first sub-plate part and a second sub-plate part connected in sequence, and the connection between the first sub-plate part and the second sub-plate part is bent toward the inner cavity of the annular structure to form the guide part;

[0011] The first subplate portion and the second subplate portion are configured to bend as the guide portion moves toward the inner cavity of the annular structure and to be fixed to form the partition structure as the guide portion stops.

[0012] In some embodiments of this utility model, a third connecting portion is provided on the first sub-plate portion, and the third connecting portion is disposed in the docking area where the first sub-plate portion connects with the second sub-plate portion when it is bent; a fourth connecting portion is provided on the second sub-plate portion, and the fourth connecting portion is disposed in the docking area where the second sub-plate portion connects with the first sub-plate portion when it is bent; the third connecting portion and the fourth connecting portion are configured such that their connection area gradually increases as the guide portion moves away from the first plate and gradually decreases as the guide portion moves closer to the first plate.

[0013] In some embodiments of this utility model, the third connecting part includes a plurality of male buckles spaced apart from each other along the length direction of the first plate, and the fourth connecting part includes a plurality of female buckles that correspond one-to-one with the male buckles.

[0014] In some embodiments of this utility model, the first sub-plate portion and the second sub-plate portion have the same length.

[0015] In some embodiments of this utility model, at least one clearance hole is provided on the second plate, and the clearance hole is provided directly opposite the deformable part so that the deformable part can pass through the clearance hole after being bent to a certain extent.

[0016] In some embodiments of this utility model, the first plate body further includes non-deformable portions respectively connected to both ends of the deformable portion, and the thickness of the deformable portion is 0.5-0.8 times that of the non-deformable portion.

[0017] In some embodiments of this utility model, a heat exchanger is also provided, which includes the tube clamp described above.

[0018] In some embodiments of this utility model, an air conditioner is also provided, which includes the heat exchanger described above.

[0019] This utility model provides a pipe clamp, a heat exchanger, and an air conditioner. The pipe clamp includes a first plate and a second plate that can be connected to form an annular structure to accommodate at least two heat exchange tubes. A deformation part is provided on the first plate, allowing it to bend away from the first plate to form a partition structure, dividing the inner cavity of the annular structure into at least two sub-cavities to accommodate the ends of at least two heat exchange tubes, thus enabling the rapid connection of two rows of heat exchange tubes into one unit. Furthermore, by controlling the degree of deformation of the deformation part, the size of the sub-cavities can be adjusted to accommodate heat exchange tubes of different sizes, ensuring the pipe clamp is tightly secured to the heat exchange tubes. This locks the heat exchange tubes of two adjacent heat exchange tube rows together, improving the connection stability of the two heat exchange tube rows. In other words, this utility model, by controlling the connection state of the first and second plates and the deformation state of the deformation part, can achieve rapid connection of heat exchange tube rows and ensure connection stability between heat exchange tube rows by adapting to heat exchange tubes of different sizes.

[0031] like Figures 1-5As shown, this utility model provides a pipe clamp 10, including a first plate 100 and a second plate 200. One end of the first plate 100 has a first connecting portion 101. One end of the second plate 200 is connected to the end of the first plate 100 away from the first connecting portion 101, and the other end of the second plate 200 is detachably connected to the other end of the first connecting portion 101. When the two ends of the first plate 100 and the second plate 200 are respectively connected, the first plate 100 and the second plate 200 are connected to form an annular structure. At least one deformable portion 110 is provided on the first plate 100. The deformable portion 110 is configured to bend toward the inner cavity of the annular structure and is fixed after bending to form a partition structure to divide the inner cavity of the annular structure.

[0032] In this configuration, one end of the first plate 100 and one end of the second plate 200 are generally fixedly connected; the other end of the first plate 100 and the other end of the second plate 200 can be detached and connected. When the two are detached, the annular structure can be opened and the heat exchange tube bank to be connected can be inserted; when the two are connected, the first plate 100 and the second plate 200 can be connected to form an annular structure.

[0033] The deformable part 110 is part of the first plate 100. It is configured to bend toward the inner cavity of the annular structure and be fixed in a bent state after bending to form a partition structure. In essence, when the first plate 100 and the second plate 200 are connected at both ends, a part of the first plate 100 bends (or protrudes) toward the second plate 200 to a certain extent to form a partition structure, dividing the annular inner cavity into two sub-cavities. However, since the length of the first plate 100 is limited, the greater the degree of bending (protrusion) of the deformable part 110 and the farther the end of the deformable part 110 is from the first plate 100, the smaller the sub-cavities separated by the partition structure. Thus, the size of the sub-cavities can be adjusted by the degree of bending of the deformable part 110 to accommodate heat exchange tubes of different sizes, thereby ensuring that the tube clamp 10 can be tightly clamped on the heat exchange tube and improving the connection stability between the two rows of heat exchange tubes.

[0034] It is understood that the pipe clamp 10 includes a first plate 100 and a second plate 200 that can be connected to form an annular structure to accommodate at least two heat exchange tubes. A deformation portion 110 is provided on the first plate 100, allowing the deformation portion 110 to bend towards the inner cavity of the annular structure and remain bent after bending, thereby forming a partition structure to divide the inner cavity of the annular structure into at least two sub-cavities. This enables the pipe section to accommodate at least two heat exchange tubes, allowing for the rapid connection of two rows of heat exchange tubes into a single unit. Simultaneously, it controls... The deformation degree of the deformation part 110 can be adjusted to change the size of the sub-cavity to accommodate heat exchange tubes of different sizes, so that the tube clamp 10 is tightly locked onto the heat exchange tube, and the heat exchange tubes of two adjacent heat exchange tube banks are locked together by a tube clamp 10, thereby improving the connection stability of the two heat exchange tube banks. In other words, by controlling the connection state of the first plate 100 and the second plate 200 and the deformation state of the deformation part 110, this utility model can realize the rapid connection of heat exchange tube banks and adapt to heat exchange tubes of different sizes, ensuring the connection stability between heat exchange tube banks.

[0035] In some embodiments, one end of the first plate 100 has a first connecting portion 101. One end of the second plate 200 is connected to the end of the first plate 100 away from the first connecting portion 101, and the other end of the second plate 200 has a second connecting portion 201 that is detachably connected to the first connecting portion 101. When the first connecting portion 101 and the second connecting portion 201 are connected, the first plate 100 and the second plate 200 are connected to form a ring structure.

[0036] The first connecting part 101 and the second connecting part 201 are detachably connected, that is, the first connecting part 101 and the second connecting part 201 can switch between a detached state and a connected state; when the first connecting part 101 and the second connecting part 201 are connected, the two ends of the first plate 100 and the two ends of the second plate 200 are connected respectively, thereby forming a ring structure.

[0037] In some embodiments, the deformable portion 110 has a guide portion 113 that protrudes toward the inner cavity of the annular structure. The deformable portion 110 is configured to gradually bend as the guide portion 113 moves toward the inner cavity of the annular structure and to be fixed to form a partition structure as the guide portion 113 stops moving.

[0038] The guide portion 113 is a part of the deformable portion 110, which is formed by bending a part of the deformable portion 110 toward the inner cavity of the annular structure.

[0039] It is understandable that by providing the guide portion 113, the deformable portion 110 is in a pre-bent state before deformation occurs. Even if the deformable portion 110 has a tendency to bend, the deformable portion 110 will bend along the bending direction of the guide portion 113 when it begins to bend, thus preventing the bending direction of the deformable portion 110 from deviating from the predetermined direction.

[0040] In some embodiments, the deformable portion 110 includes a first sub-plate portion 111 and a second sub-plate portion 112 connected in sequence, and the connection between the first sub-plate portion 111 and the second sub-plate portion 112 is bent toward the inner cavity of the annular structure to form a guide portion 113. The first sub-plate portion 111 and the second sub-plate portion 112 are configured to bend as the guide portion 113 moves toward the inner cavity of the annular structure and to be fixed as the guide portion stops to form a partition structure.

[0041] Wherein, the end of the first sub-plate portion 111 near the second sub-plate portion 112 is bent toward the inner cavity of the annular structure, and the end of the second sub-plate portion 112 near the first sub-plate portion 111 is bent toward the inner cavity of the annular structure, thereby forming a guide portion 113 bent toward the inner cavity of the annular structure at the connection between the first sub-plate portion 111 and the second sub-plate portion 112.

[0042] It should be noted that the first sub-plate portion 111 bends relative to its original state as the guide portion 113 moves. The degree of bending increases as the guide portion 113 moves further toward the inner cavity of the annular structure. Generally, the bending angle of the first sub-plate portion 111 is the angle between the bent first sub-plate portion 111 and the unbent first sub-plate portion 111, that is, the bending angle of the first sub-plate portion 111 is the angle between the bent first sub-plate portion 111 and the undeformed first plate body 100. In other words, the farther the guide member moves away from the first plate body 100, the greater the bending angle of the first sub-plate portion 111. Similarly, the second sub-plate portion 112 bends relative to its original state as the guide portion 113 moves. The degree of bending increases as the guide portion 113 moves away from the first plate body 100. Generally speaking, the bending angle of the second sub-plate portion 112 is the angle between the bent second sub-plate portion 112 and the unbent second sub-plate portion 112. That is, the bending angle of the second sub-plate portion 112 is the angle between the bent first sub-plate portion 111 and the undeformed first plate body 100. In other words, the farther the guide member moves away from the first plate body 100, the greater the bending angle of the second sub-plate portion 112.

[0043] It is understandable that by providing the guide portion 113, the first sub-plate portion 111 and the second sub-plate portion 112 are in a pre-bent state, so that the first sub-plate portion 111 and the second sub-plate portion 112 can be bent along a predetermined path, thereby preventing the bending direction of the deformation portion 110 from deviating from the predetermined direction.

[0044] In some embodiments, a third connecting portion 103 is provided on the first sub-plate portion 111, and the third connecting portion 103 is disposed in the mating area where the first sub-plate portion 111 connects with the second sub-plate portion 112 when the first sub-plate portion 111 is bent; a fourth connecting portion 104 is provided on the second sub-plate portion 112, and the fourth connecting portion 104 is disposed in the mating area where the second sub-plate portion 112 connects with the first sub-plate portion 111. The third connecting portion 103 and the fourth connecting portion 104 are configured such that their connection area increases as the guide portion 113 moves away from the first plate body 100 and decreases as the guide portion 113 moves closer to the first plate body 100.

[0045] It should be noted that as the deformable portion gradually bends, the side of the first sub-plate portion 111 facing away from the inner cavity of the annular structure gradually connects with the side of the second sub-plate portion 112 facing away from the inner cavity of the annular structure. Therefore, the mating area connecting the first sub-plate portion 111 and the second sub-plate portion 112 is located on the side of the first sub-plate portion 111 facing away from the inner cavity of the annular structure, and the mating area on the second sub-plate portion 112 connecting with the first sub-plate portion 111 is located on the side of the second sub-plate portion 112 facing away from the inner cavity of the annular structure. That is, the third connecting portion 103 is provided on the side of the first sub-plate portion 111 facing away from the inner cavity of the annular structure, and the fourth connecting portion... 104 is disposed on the side of the second sub-plate portion 112 away from the inner cavity of the annular structure. Therefore, as the first sub-plate portion 111 and the second sub-plate portion 112 gradually bend, their back sides come into contact with each other, thereby causing the third connecting portion 103 to gradually connect with the fourth connecting portion 104. That is, as the guide portion 113 gradually moves away from the first plate body 100, the greater the degree of bending of the first sub-plate portion 111 and the second sub-plate portion 112, the greater the contact area between the back sides of the first sub-plate portion 111 and the second sub-plate portion 112, and thus the greater the connection area between the third connecting portion 103 and the fourth connecting portion 104.

[0046] It is understandable that as the connection area between the third connecting part 103 and the fourth connecting part 104 gradually increases, the connection stability between the third connecting part 103 and the fourth connecting part 104 gradually increases, and the bending state of the first sub-plate part 111 and the second sub-plate part 112 is easier to maintain, thereby ensuring the connection stability between the tube clamp 10 and the heat exchange tube; the connection area between the third connecting part 103 and the fourth connecting part 104 can be adjusted so that the first sub-plate part 111 and the second sub-plate part 112 are in different bending degrees, thereby forming sub-cavities of different sizes to accommodate heat exchange tubes of different sizes.

[0047] In some embodiments, the third connecting part 103 and the fourth connecting part 104 are both Velcro.

[0048] In some embodiments, the third connecting portion 103 includes a plurality of male buckles spaced apart from each other along the length direction of the first plate 100, and the fourth connecting portion 104 includes a plurality of female buckles corresponding to the male buckles. Each male buckle is provided with one female buckle. As the bending degree of the first sub-plate portion 111 and the second sub-plate portion 112 increases, the number of male buckles on the first sub-plate portion 111 and female buckles on the second sub-plate portion 112 that are engaged gradually increases.

[0049] As the number of male latches on the first sub-plate 111 and female latches on the second sub-plate 112 gradually increases, the bending state between the first sub-plate 111 and the second sub-plate 112 becomes more stable. By adjusting the number of male latches on the first sub-plate 111 and female latches on the second sub-plate 112, the deformation section 110 can be divided into sub-cavities of different sizes to accommodate heat exchange tubes of different sizes.

[0050] In some embodiments, the first sub-plate portion 111 and the second sub-plate portion 112 have the same length.

[0051] That is, the guide portion 113 is located at the midpoint of the deformation portion 110, which allows the first sub-plate portion 111 and the second sub-plate portion 112 to bend symmetrically, so as to make the sub-cavities separated by the deformation portion 110 as consistent as possible; for example, when only one deformation portion 110 is provided on the first plate body 100, and the deformation portion 110 is located in the middle of the first plate body 100, the sub-cavities formed after the deformation portion 110 is bent are the same size.

[0052] In some embodiments, at least one clearance hole 210 is provided on the second plate 200, and the clearance hole 210 is provided directly opposite the deformable part 110 so that the deformable part 110 can pass through the clearance hole 210 after being bent to a certain extent.

[0053] It is understandable that by setting the clearance hole 210, the deformable part 110 can bend to a certain extent and then continue to bend through the clearance hole 210, thereby further reducing the size of the sub-cavity and allowing the tube clamp 10 to adapt to the connection between smaller heat exchange tubes.

[0054] In some embodiments, one clearance hole 210 may be provided for one deformation part 110, or multiple deformation parts 110 may be provided for one clearance hole 210.

[0055] In some embodiments, the first plate 100 further includes non-deformable portions 120 respectively connected to both ends of the deformable portion 110, wherein the thickness of the deformable portion 110 is 0.5-0.8 times that of the non-deformable portion 120.

[0056] The first plate 100 is generally made of plastic. By reducing the thickness of the deformable part 110, the deformable part 110 can be bent more easily, thus making it easier to form a partition structure.

[0057] Understandably, if the thickness of the deformable portion 110 is too thin relative to the non-deformable portion 120, the overall strength of the first plate 100 will be low. If the thickness of the deformable portion 110 is too thick, the bending of the deformable portion 110 will be more difficult. Therefore, the thickness of the deformable portion 110 is limited to 0.5-0.8 times that of the non-deformable portion 120 to ensure both the bendability of the deformable portion 110 and the overall strength of the first plate 100.

[0058] In some embodiments, the thickness of the deformable portion 110 is 0.5 times that of the non-deformable portion 120.

[0059] In some embodiments, the thickness of the deformable portion 110 is 0.6 times that of the non-deformable portion 120.

[0060] In some embodiments, the thickness of the deformable portion 110 is 0.8 times that of the non-deformable portion 120.

[0061] In some embodiments, the first connecting portion 101 is one of a buckle and a buckle hole, and the second connecting portion 201 is the other of a buckle and a buckle hole.

[0062] That is, the first plate 100 and the second plate 200 are snap-fit ​​connected.

[0063] In some embodiments, the end of the first plate 100 away from the first connecting portion 101 is integrally connected to the end of the second plate 200 away from the second connecting portion 201.

[0064] In some embodiments, the first plate 100 includes a plurality of deformable portions 110 connected in sequence, and the plurality of deformable portions 110 can be bent simultaneously to define a plurality of sub-cavities.

[0065] In some embodiments, a heat exchanger 20 is also provided, which includes the aforementioned tube clamp 10. Since the tube clamp 10 includes at least some or all of the above embodiments, the heat exchanger 20 has at least the beneficial effects of some or all of the above embodiments, which will not be described in detail here.

[0066] In some embodiments, the heat exchanger 20 includes a first heat exchange tube bank 21, a second heat exchange tube bank 22, and a tube clamp 10, wherein the heat exchange tubes of the first heat exchange tube bank 21 and the heat exchange tubes of the second heat exchange tube bank 22 are both connected to the same tube clamp 10.

[0067] In some embodiments, an air conditioner is also provided, the refrigeration device including the heat exchanger 20 described above. Since the heat exchanger 20 includes at least some or all of the embodiments of the pipe clamp 10 described above, the air conditioner has at least the beneficial effects of some or all of the embodiments described above, which will not be described in detail here.

[0068] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made based on the contents of the present utility model specification and drawings under the application concept of the present utility model, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
