Description

Technical Field

[0001] The utility model relates to the technical field of fixing mechanisms for heat pump fins, and more particularly to a fixing clip for heat pump fins and the heat pump fins. Background Art

[0002] A heat pump is a device that transfers heat from a low-temperature environment to a high-temperature environment and is widely used in heating, cooling, and hot water supply. The efficient operation of a heat pump depends on its multiple internal components, of which the heat exchanger is a core component. The heat exchanger's fins increase the heat exchange area and improve heat transfer efficiency. However, securing the fins is a problem, as loose fins can reduce heat transfer efficiency and even cause equipment failure.

[0003] Traditional fin fixing methods often use universal clamps, welding, or adhesives. Each of these methods has its advantages and disadvantages: universal clamps are simple in structure but can be insecure and prone to loosening due to thermal expansion and contraction; welding offers good fixing effects but is complex and costly; and adhesives, while convenient, can age over time, leading to bond failure. Utility Model Content

[0004] The purpose of the utility model is to overcome the problem of insufficient reliability of the simple heat pump fin fixing method in the prior art, and to provide a heat pump fin fixing clip and a heat pump fin, which are easy to operate, have good fixing effect and high reliability.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] Provided is a fixing clamp for heat pump fins, the fixing clamp is used to clamp and fix the fins, the ends of the fins are provided with a plurality of copper tubes; the fixing clamp comprises two clamping units located at the top and bottom of the fins respectively, the clamping units comprising

[0007] The first clamping portion is used to clamp and fix the fin in a first direction, is provided with a plurality of through holes for the copper tube to pass through, and is detachably connected to the fin;

[0008] The second clamping portion is used to clamp and fix the fin in the second direction, and is detachably connected to the first clamping portion and the fin. The first clamping portion and the second clamping portion are arranged perpendicularly.

[0009] The heat pump fin retaining clamp of the present invention is used to clamp and secure the fins. Specifically, a first clamping portion secures the ends of the fins, a copper tube is passed through the through-hole, and the first clamping portion is positioned vertically to limit the fins and prevent them from moving. Simultaneously, a second clamping portion clamps and secures the two fins in a horizontal position to prevent them from loosening. Furthermore, the second clamping portion is connected to the first clamping portion, ensuring that the second clamping portion remains in its original position and does not shift. In actual use, the fins are secured with a clamping unit at the top and bottom of the fins. The first clamping portion is connected to the second clamping portion and the fins using screws, which is simple, quick, efficient, and secure. The retaining clamp of the present invention is more secure than traditional fixing devices and does not fall off during fin transportation. Therefore, it can be manufactured as a component along with the fins, increasing heat pump assembly efficiency.

[0010] Furthermore, the first clamping portion includes a positioning plate and a fixing plate connected to each other, the plurality of through holes being arranged from top to bottom along the positioning plate, the fixing plate being arranged perpendicular to the positioning plate, and the fixing plates being detachably connected to the fins and the second clamping portion, respectively. The positioning plate is used to connect with the copper tube to achieve positioning, and the fixing plate is used to connect with the fins and simultaneously secure the positioning plate.

[0011] Furthermore, the fixing plate includes a top fixing plate and a bottom fixing plate, both of which are connected to the side of the positioning plate, the top fixing plate is detachably connected to the fin and its top is flush with the top of the positioning plate, the bottom fixing plate is detachably connected to the fin and its bottom is flush with the bottom of the positioning plate, and the top fixing plate or the bottom fixing plate is also detachably connected to the second clamping portion. Both the top fixing plate and the bottom fixing plate are used to connect to the positioning plate for fixation; at the same time, the top fixing plate is used to connect to the second clamping portion and be fixedly connected to the fin when the clamping unit is fixed to the top of the fin; the bottom fixing plate is used to connect to the second clamping portion and be fixedly connected to the fin when the clamping unit is fixed to the bottom of the fin; and the second clamping portion is located at the top or bottom of the fin.

[0012] Furthermore, the top fixing plate and the bottom fixing plate are integrally formed with the positioning plate. The top fixing plate, the bottom fixing plate and the positioning plate are formed by bending sheet metal parts, eliminating the complicated welding process and increasing efficiency.

[0013] Furthermore, the second clamping portion is a U-shaped structure, and the fins are clamped in the U-shaped structure. The U-shaped structure clamps the two fins from the outside, and then locks and fixes them with the first clamping portion through the side of the U shape.

[0014] Furthermore, the second clamping portion includes a first end plate, a connecting plate, and a second end plate, the fin is clamped between the first end plate and the second end plate, the second end plate is detachably connected to the first clamping portion and the fin, or the second end plate is detachably connected to the first clamping portion and the fin. The first end plate, the connecting plate, and the second end plate are connected and surrounded to form a U-shaped structure, the opposite inner sides of the first end plate and the second end plate are located on both sides of the fin and abut against the fin, the connecting plate is located at the top of the fin facing the first end plate and the second end plate, and abuts against the fin; the second end plate is also connected to the top fixing plate or the bottom fixing plate of the first clamping portion by screws, and is connected and fixed to the fin.

[0015] Furthermore, the second clamping portion includes a first movable plate and a second movable plate, both of which are right-angled plate-shaped structures. The first movable plate is provided with a first positioning hole, and the second movable plate is provided with a plurality of second positioning holes in sequence. The first movable plate is connected to the second movable plate by screws passing through the first positioning hole and one of the second positioning holes in sequence to form a U-shaped structure. The fin is clamped between the first movable plate and the second movable plate. The second movable plate is also detachably connected to the first clamping portion and the fin. Although the first movable plate and the second movable plate also form a U-shaped structure, the size of this U-shaped structure is adjustable. Specifically, by moving the first movable plate, the first positioning hole is aligned with the second positioning holes at different positions. By screw connection, the size of the U-shaped structure formed by the first movable plate and the second movable plate can be adjusted, so that it can be suitable for fins of different thicknesses and achieve a clamping and fixing effect.

[0016] Furthermore, the second movable plate is provided with slots on both sides, and the first movable plate is movably engaged with the second movable plate through the slots. The first movable plate can slide along the slots to facilitate adjustment of the relative position of the first movable plate and the second movable plate, thereby facilitating the second clamping portion to adapt to fins of different thicknesses.

[0017] Furthermore, the second clamping portion includes a first movable plate, a clamping plate, and a second movable plate. The first movable plate and the second movable plate are both clamped to the clamping plate and respectively connected to the fins. The second movable plate is also connected to the first clamping portion. The first movable plate, the clamping plate, and the second movable plate also form a U-shaped structure, except that the clamping plate exists separately rather than being integrally formed with the second movable plate. The principle is similar to that described above. The clamping plate is used to adjust the relative position of the first movable plate and the second movable plate, thereby facilitating the second clamping portion to adapt to fins of different thicknesses.

[0018] The present invention also provides a heat pump fin, which is fixed with the heat pump fin fixing clip described above. By adding the fixing clip when the fin leaves the factory, the fin is firmly and reliably fixed, and the effects of thermal expansion and contraction must be taken into account to ensure that the fin remains stable under different temperature conditions.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] The heat pump fin fixing clamp of the present invention is more secure than traditional fixing devices and will not fall off during the transportation of the fins. Therefore, it can be produced together with the fins as a component, making the heat pump assembly production more efficient. In addition, it has a firm and reliable fixing effect, and it also needs to take into account the effects of thermal expansion and contraction to ensure that the fins can remain stable under different temperature conditions. It also has a simple structure and is easy to mass produce and install. In summary, the heat pump fin fixing clamp of the present invention can not only improve the overall performance of the heat pump, but also extend the service life of the equipment, and has important practical value and economic significance.

[0033] Example 1

[0034] like Figures 1 to 3 As shown, this embodiment is a first embodiment of a heat pump fin fixing clamp, which is used to clamp and fix the fin 3. The end of the fin 3 is provided with multiple copper tubes 4; it includes two clamping units located at the top and bottom of the fin 3 respectively, and the clamping unit includes

[0035] The first clamping portion 1 is used to clamp and fix the fin 3 in a first direction, has a plurality of through holes 111 for the copper 4 tubes to pass through, and is detachably connected to the fin 3;

[0036] The second clamping portion 2 is used to clamp and fix the fin 3 in the second direction, and is detachably connected to the first clamping portion 1 and the fin 3 . The first clamping portion 1 and the second clamping portion 2 are arranged perpendicularly.

[0037] The fixing clamp of the heat pump fin of the present invention is used to clamp and fix the fin 3. Specifically, the end of the fin 3 is fixed by the first clamping part 1, and the copper 4 tube is passed through the through hole 111. Then, the first clamping part 1 is set in the vertical direction to limit the fin 3 and prevent the fin 3 from moving. At the same time, the second clamping part 2 is used to clamp and fix the two side-by-side fins 3 in the horizontal direction to prevent the two fins 3 from loosening. Moreover, the second clamping part 2 is connected to the first clamping part 1 so that the second clamping part 2 can always remain in the original position without displacement. In actual use, it is necessary to fix the fin 3 with a clamping unit at the top and bottom of the fin 3 respectively. When connecting the first clamping part 1 with the second clamping part 2 and the fin 3, it is only necessary to connect them with screws. It is very simple and fast, efficient, and can ensure firmness. The fixing clip of the present invention is more secure than a traditional fixing device and will not fall off during the transportation of the fin 3. Therefore, it can be produced together with the fin 3 as a component, thereby improving the production efficiency of heat pump assembly.

[0038] As one embodiment of the present invention, the first clamping portion 1 includes a positioning plate 11 and a fixing plate 12 connected to each other. A plurality of through holes 111 are arranged from top to bottom along the positioning plate 11. The fixing plate 12 is arranged perpendicular to the positioning plate 11. The fixing plate 12 is detachably connected to the fin 3 and the second clamping portion 2 respectively. The positioning plate 11 is used to connect with the copper tube 4 to achieve positioning, and the fixing plate 12 is used to connect with the fin 3 and simultaneously fix the positioning plate 11. The copper 4 tube is provided with a protruding fin 3 end. In the present embodiment, there are 3 to 5 through holes 111 on the positioning plate 11 for the copper 4 tube to pass through. Within the scope of knowledge of those skilled in the art, the number of through holes 111 is not limited to the number listed above; since the distances from the top and the bottom to the copper 4 tube are different, the distance from the center of the through hole 111 near the top of the positioning plate 11 to the top of the positioning plate 11 is greater than the distance from the center of the through hole 111 near the bottom of the positioning plate 11 to the bottom of the positioning plate 11, so as to facilitate adaptation to the copper 4 tube and the installation of the positioning plate 11. The copper 4 tube provided through the positioning plate 11 actually plays a role in positioning the positioning plate 11, which can not only well meet the needs of the fixing clamp to avoid the copper 4 tube, but also can make use of the copper 4 tube.

[0039] As one embodiment of the present invention, the fixing plate 12 includes a top fixing plate 121 and a bottom fixing plate 122. The top fixing plate 121 and the bottom fixing plate 122 are both connected to the side of the positioning plate 11. The top fixing plate 121 is detachably connected to the fin 3 and its top is flush with the top of the positioning plate 11. The bottom fixing plate 122 is detachably connected to the fin 3 and its bottom is flush with the bottom of the positioning plate 11. The top fixing plate 121 or the bottom fixing plate 122 is also detachably connected to the second clamping portion 2. The top fixing plate 121 and the bottom fixing plate 122 are both used to connect and fix with the positioning plate 11. At the same time, the top fixing plate 121 is used to connect with the second clamping portion 2 when the clamping unit is fixed to the top of the fin 3, and is connected and fixed to the fin 3. The bottom fixing plate 122 is used to connect with the second clamping portion 2 when the clamping unit is fixed to the bottom of the fin 3, and is connected and fixed to the fin 3. The second clamping portion 2 is located at the top or bottom of the fin 3.

[0040] As one embodiment of the present invention, the top fixing plate 121 and the bottom fixing plate 122 are integrally formed with the positioning plate 11. The top fixing plate 121 and the bottom fixing plate 122 and the positioning plate 11 are obtained by bending sheet metal parts, eliminating the complicated welding process and being more efficient.

[0041] As one embodiment of the present invention, the second clamping portion 2 is a U-shaped structure, and the fins 3 are clamped in the U-shaped structure. The U-shaped structure clamps the two fins 3 from the outside, and then locks and fixes them with the first clamping portion 1 through the side of the U shape.

[0042] As one embodiment of the present invention, the second clamping portion 2 includes a first end plate 21, a connecting plate 22, and a second end plate 23. The fin 3 is clamped between the first end plate 21 and the second end plate 23. The second end plate 23 is detachably connected to the first clamping portion 1 and the fin 3, or the second end plate 23 is detachably connected to the first clamping portion 1 and the fin 3. The first end plate 21, the connecting plate 22, and the second end plate 23 are connected and surrounded to form a U-shaped structure. The relative inner sides of the first end plate 21 and the second end plate 23 are both located on both sides of the fin 3 and are in contact with the fin 3. The connecting plate 22 is located at the top of the fin 3 facing the first end plate 21 and the second end plate 23 and is in contact with the fin 3. The second end plate 23 is also connected to the top fixing plate 121 or the bottom fixing plate 122 of the first clamping portion 1 by screws, and is also connected and fixed to the fin 3. Furthermore, the second end plate 23 is respectively penetrated by a third mounting hole 231 and a fourth mounting hole 232, the top fixing plate 121 is provided with a first mounting hole 1211, and the bottom fixing plate 122 is provided with a second mounting hole 1221. The second end plate 23 is connected to the fin 3 after passing screws through the third mounting hole 231 and the first mounting hole 1211, or the second end plate 23 is connected to the fin 3 after passing screws through the fourth mounting hole 232 and the second mounting hole 1221.

[0043] In this embodiment, the first clamping portion 1 of the clamping unit located at the top of the fin 3 is located on the side of the fin 3, the second clamping portion 2 is located at the top of the fin 3, and the second clamping portion 2 is connected to the top fixed plate 121; the first clamping portion 1 of the clamping unit located at the bottom of the fin 3 is located on the side of the fin 3, the second clamping portion 2 is located at the bottom of the fin 3, and the second clamping portion 2 is connected to the bottom fixed plate 122. The structures of the top clamping unit and the bottom clamping unit are similar.

[0044] The working principle of the fixing clip of the heat pump fin 3 in this embodiment is as follows:

[0045] First, fix the top clamping unit: place the positioning plate 11 on the side of the fin 3, pass the copper tube 4 through the through hole 111 of the positioning plate 11, and then place the connecting plate 22 on the top of the fin 3, with the first end plate 21 and the second end plate 23 located on both sides of the fin 3, and then use screws to connect the second end plate 23 and the top fixing plate 121 to the fin 3; similarly, fix the bottom clamping unit, place the positioning plate 11 on the side of the fin 3, pass the copper 4 tube through the through hole 111 of the positioning plate 11, and then place the connecting plate 22 on the bottom of the fin 3, with the first end plate 21 and the second end plate 23 located on both sides of the fin 3, and then use screws to connect the second end plate 23 and the bottom fixing plate 122 to the fin 3, thus completing the connection and fixation of the entire fixing clamp to the fin 3.

[0046] Example 2

[0047] like Figures 4 to 6 As shown, this embodiment is a second embodiment of a fixing clamp for a heat pump fin. This embodiment is similar to the first embodiment, except that the second clamping portion 2 includes a first movable plate 24 and a second movable plate 25, both of which are right-angled plate structures. The first movable plate 24 is provided with a first positioning hole 241, and the second movable plate 25 is provided with a plurality of second positioning holes 251 in sequence. The first movable plate 24 is connected to the second movable plate 25 to form a U-shaped structure after screws are passed through the first positioning hole 241 and one of the second positioning holes 251 in sequence. The fin 3 is clamped between the first movable plate 24 and the second movable plate 25, and the second movable plate 25 is also detachably connected to the first clamping portion 1 and the fin 3. Although the first movable plate 24 and the second movable plate 25 also form a U-shaped structure, the size of this U-shaped structure is adjustable. Specifically, by moving the first movable plate 24, the first positioning hole 241 is aligned with the second positioning hole 251 at different positions, and connected by screws, the size of the U-shaped structure formed by the first movable plate 24 and the second movable plate 25 can be adjusted, so that it can be suitable for fins 3 of different thicknesses to achieve a clamping and fixing effect.

[0048] Furthermore, slots 26 are provided on both sides of the second movable plate 25, and the first movable plate 24 is movably engaged with the second movable plate 25 via the slots 26. The first movable plate 24 can slide along the slots 26, making it easy to adjust the relative position of the first movable plate 24 and the second movable plate 25, thereby facilitating the second clamping portion 2 to adapt to fins 3 of different thicknesses.

[0049] The working principle of the fixing clip of the heat pump fin 3 in this embodiment is as follows:

[0050] First, fix the clamping unit at the top: place the positioning plate 11 on the side of the fin 3, pass the copper 4 tube through the through hole 111 of the positioning plate 11, then place the second movable plate 25 on the top of the fin 3 and make the side contact with the fin 3, adjust the relative position of the first movable plate 24 and the second movable plate 25 through the slot 26, and make the first movable plate 24 contact with the fin 3, then use screws to fasten the first movable plate 24 and the second movable plate 25, and at the same time connect them to the top of the fin 3, and then use screws to connect the first movable plate 24 and the top fixed plate 121 to the fin 3. Similarly, fix the clamping unit at the bottom, place the positioning plate 11 on the side of the fin 3, pass the copper tube 4 through the through hole 111 of the positioning plate 11, adjust the relative position of the first movable plate 24 and the second movable plate 25 through the slot 26, and make the first movable plate 24 abut against the side of the fin 3, then use screws to fasten the first movable plate 24 and the second movable plate 25, and at the same time connect them to the bottom of the fin 3, and then use screws to connect the first movable plate 24 and the bottom fixed plate 122 to the fin 3; that is, the connection and fixation of the entire fixing clamp to the fin 3 are completed.

[0051] The fixing clip of this embodiment is different from that of embodiment 1. The fixing clip of this embodiment can adjust the size of the second clamping portion 2 to adapt to fins 3 of different thicknesses. The fixing clip of embodiment 1 can only adapt to fins 3 of a specific thickness.

[0052] Example 3

[0053] like Figure 7 As shown, this embodiment is a third embodiment of a fixing clamp for heat pump fins 3. This embodiment is similar to the first embodiment, except that the second clamping portion 2 includes a first movable plate 24, a clamping plate 27, and a second movable plate 25. The first movable plate 24 and the second movable plate 25 are both clamped to the clamping plate 27 and respectively connected to the fins 3. The second movable plate 25 is also connected to the first clamping portion 1. The first movable plate 24, the clamping plate 27, and the second movable plate 25 also form a U-shaped structure, except that the clamping plate 27 exists separately rather than being integrally formed with the second movable plate 25. The principle is similar to the previous embodiment. The clamping plate 27 is used to adjust the relative position of the first movable plate 24 and the second movable plate 25, thereby facilitating the second clamping portion 2 to adapt to fins 3 of different thicknesses.

[0054] The working principle of the fixing clip of the heat pump fin 3 in this embodiment is as follows:

[0055] First fix the clamping unit at the top: place the positioning plate 11 on the side of the fin 3, pass the copper 4 tube through the through hole 111 of the positioning plate 11, then plug the second movable plate 25 with the clamping plate 27 and place the second movable plate 25 on the top of the fin 3 with the side abutting against the fin 3, then clamp the first movable plate 24 with the clamping plate 27, adjust the relative position of the first movable plate 24 and the second movable plate 25 through the clamping plate 27, and make the first movable plate 24 and the second movable plate 25 abut against the side of the fin 3 respectively, then use screws to lock and fix the fin 3 from the top of the fin 3, and then use screws to connect the first movable plate 24 and the top fixed plate 121 to the fin 3; similarly, fix the clamping unit at the bottom Unit, place the positioning plate 11 on the side of the fin 3, pass the copper 4 tube through the through hole 111 of the positioning plate 11, then plug the second movable plate 25 with the clamping plate 27 and place the second movable plate 25 at the bottom of the fin 3 and abut the side with the fin 3, then clamp the first movable plate 24 with the clamping plate 27, adjust the relative position of the first movable plate 24 and the second movable plate 25 through the clamping plate 27, and make the first movable plate 24 and the second movable plate 25 abut the side of the fin 3 respectively, and then use screws to lock and fix the fin 3 from the bottom of the fin 3, and then use screws to connect the first movable plate 24 and the bottom fixed plate 122 to the fin 3; that is, the connection and fixation of the entire fixing clip to the fin 3 are completed.

[0056] The fixing clip of this embodiment is different from that of embodiment 1. The fixing clip of this embodiment can adjust the size of the second clamping portion 2 to adapt to fins 3 of different thicknesses. The fixing clip of embodiment 1 can only adapt to fins 3 of a specific thickness.

[0057] Example 4

[0058] like Figures 8 and 9 As shown, this embodiment is an embodiment of a heat pump fin 3. This embodiment is similar to the first embodiment, except that the heat pump fin is fixed with a heat pump fin fixing clip as described above. By adding the fixing clip when the fin leaves the factory, a firm and reliable fixing effect is achieved. The effects of thermal expansion and contraction must also be taken into account to ensure that the fin remains stable under different temperature conditions.

[0059] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
