Description

Technical Field

[0001] The utility model relates to the technical field of heat pumps, in particular to a fixing structure of a fin heat exchanger and a heat pump. Background Art

[0002] Finned heat exchangers, especially those operating in cold and humid environments, are prone to severe frost on their fins. The low-temperature water melted by defrosting is inherently cooler, and in extremely cold outdoor environments, condensed water (both condensed and defrosted) can quickly freeze and accumulate at the base of the fins, affecting heat transfer and even bursting the heat transfer tubes. In severe cases, the entire unit may be covered in ice, seriously impacting its reliability. Therefore, it's often necessary to collect and quickly drain the water after the fins have been defrosted.

[0003] For the flat-plate water tray, in order to facilitate the drainage of condensed water and defrosting water from the fin heat exchanger, a raised structure is often welded on the water tray to support the fin heat exchanger. However, this method has very high processing requirements for multi-angle fin heat exchangers. It is required that the shape of the multi-angle fins cannot deviate. Otherwise, during assembly, some parts of the fin heat exchanger will not be placed on the raised structure, resulting in misalignment, affecting the appearance and affecting the rapid drainage of condensed water, thereby causing ice accumulation on the edges of the fins. Utility Model Content

[0004] Based on this, one of the purposes of the present invention is to provide a fixing structure for a fin heat exchanger. By clamping the clip structures arranged at intervals on the water receiving tray into the support frame of the multi-angle fin heat exchanger, the water receiving tray and the multi-angle fin heat exchanger can be quickly assembled and positioned, and at the same time, a leakage hole is provided to facilitate the rapid drainage of condensed water.

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "bottom", "inner", "outer", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, "first", "second", "third", and "fourth" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, unless otherwise specified, "plurality" means two or more.

[0045] It should also be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections, direct connections, connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0046] In existing heat pumps and other equipment, a raised structure is usually welded on a flat-plate structure-shaped water receiving pan to support the fin heat exchanger, so that the condensed water and defrosting water on the fin heat exchanger can drip onto the water receiving pan and be discharged through the drainage holes in the water receiving pan. However, this fixing method has very high processing requirements for multi-angle fin heat exchangers, requiring that the shape of the multi-angle fins cannot deviate. Once the fin heat exchanger is deformed, it may cause some parts of the fin heat exchanger to not fall on the raised structure during assembly, resulting in misalignment, affecting the appearance, and affecting the rapid drainage of condensed water (including condensed water and defrost water), resulting in ice accumulation on the edges of the fins, and even causing the water dripping from the fin radiator to be unable to be completely drained from the drainage holes. That is, some water dripping onto the surface of the water receiving pan will overflow in all directions and may overflow from the outside of the chassis through the gaps, causing the chassis to leak.

[0047] Based on this, the utility model provides a fixing structure of a fin heat exchanger. By clamping the clamping structure provided on the water receiving tray in the support frame of the multi-angle fin heat exchanger, the assembly positioning of the water receiving tray and the multi-angle fin heat exchanger is realized, which facilitates the rapid drainage of condensate and reduces the influence of the processing deformation of the multi-angle fin heat exchanger on the drainage of condensate.

[0048] See also Figure 1-4 The embodiment of the present application provides a fixing structure for a fin heat exchanger, comprising a water receiving tray 10 and a fin heat exchanger 20. The water receiving tray 10 is arranged below the fin heat exchanger 20 and is used to drain the condensed water from the fin heat exchanger 20. A clamping structure 12 is fixed on the upper end surface of the water receiving tray 10; the fin heat exchanger 20 is fixed with a continuous or several spaced support frames 30 along its bottom edge. The support frames 30 abut against the water receiving tray 10 and / or the clamping structure 12 to support the fin heat exchanger 20. The support frames 30 abut against the clamping structure 12 in multiple horizontal directions so that the fin heat exchanger 20 is fixed relative to the water receiving tray 10 in a horizontal plane, thereby realizing the assembly positioning of the fin heat exchanger 20 and the water receiving tray 10. The support frame 30 is provided with a leakage hole 322. The orthographic projections of the clamping structure 12 and the leakage hole 322 on the horizontal plane are completely misaligned or partially overlapped, which is conducive to the rapid drainage of condensed water.

[0049] Compared with the prior art in which the support frame is welded to the water receiving tray, in the embodiment of the present application, the fin heat exchanger 20 is fixed on the support frame 30 to avoid the influence of the fin production deformation on the appearance of the equipment, and the support frame 30 is clamped with the clamping structure 12 to achieve rapid assembly and positioning of the fin heat exchanger 20 and the water receiving tray 10, so that the support frame 30 can completely and effectively support the fin heat exchanger 20. At the same time, a leakage hole 322 is provided on the support frame 30, so that the condensation water flowing down the fin heat exchanger 20 enters the water receiving tray 10 through the leakage hole 322, thereby guiding the condensation water so that the condensation water can be discharged in time.

[0050] See also Figure 1-6 Furthermore, in some embodiments, one of the snap-fit ​​structure 12 and the support frame 30 is provided with a mounting slot, and the other is fixed within the mounting slot. A notch 344 is cut into the sidewall of the mounting slot and / or the support frame 30. The notch 344 communicates with the drain hole 322 to form a water flow path to guide water out of the support frame 30.

[0051] Specifically, in some embodiments, the mounting groove is provided on the support frame 30, and the clamping structure 12 is clamped in the mounting groove. Preferably, the clamping structure 12 contacts the bottom of the mounting groove, thereby supporting the support frame 30 and reducing deformation of the support frame 30.

[0052] As an example, the clamping structure 12 includes a non-circular positioning block, and the mounting groove is a groove body adapted to the shape of the positioning block. The positioning block is clamped in the mounting groove to prevent the fin heat exchanger 20 from being displaced relative to the water receiving tray 10.

[0053] For example, the clamping structure 12 may further include a plurality of positioning blocks, which are spaced apart along the bottom edge of the fin heat exchanger 20. This can prevent the integrated clamping structure 12 from occupying too much space on the water receiving tray 10, thereby blocking the flow of condensed water. This is more conducive to guiding the condensed water from the leakage holes 322 of the support frame 30 to the water receiving tray 10 and then flowing away from the water receiving tray 10. This prevents the fin heat exchanger 20 from being deformed during production, causing the fin heat exchanger 20 to be partially located outside the support frame 30, affecting the drainage of condensed water, and further causing condensed water to accumulate on the edges of the fins, thereby affecting the efficiency of the fin heat exchanger 20.

[0054] It is understandable that at least a portion of the positioning block avoids the water leakage hole 322, so that the condensed water can flow from the water leakage hole to the water receiving tray 10 in time and be drained away.

[0055] It is understandable that the clamping structure 12 may also be other structures that can fix the fin heat exchanger 20 to the water receiving tray 10 in the horizontal direction, which will not be described in detail here.

[0056] See also Figures 5-6Furthermore, in some embodiments, the support frame 30 includes a support plate 32 and a surrounding plate 34 extending from the edge of the support plate 32 toward the water receiving tray 10 . The support plate 32 and the surrounding plate 34 form a mounting slot. A drainage hole 322 is provided on the support plate 32 ; a cutout 344 is provided at one end of the surrounding plate 34 near the water receiving tray 10 ; the orthographic projection of the positioning block within the plane of the cutout 344 at least partially avoids the cutout 344 to prevent the positioning block from blocking the cutout 344 and facilitate the drainage of condensate through the cutout 344 .

[0057] Specifically, in some other embodiments, a mounting groove is provided on the clamping structure 12, and the support frame 30 is inserted into the mounting groove. A cutout 344 is provided on the side wall of the support frame 30 and is in communication with the water leakage hole 322; the clamping structure 12 at least partially avoids the cutout 344 so as to guide the water flow out of the support frame 30 through the cutout 344. The clamping structure 12 can be a one-piece trough structure, with the support frame 30 integrally inserted into the clamping structure 12. In this arrangement, the side wall of the clamping structure 12 is also provided with a cutout to connect to the water leakage hole 322 to prevent the clamping structure 12 from blocking the water flow path. Condensate from the fin heat exchanger can be guided into the support frame 30 through the water leakage hole 322 and then discharged to the outside of the clamping structure 12 through the cutout. The clip-on structure 12 can also be a segmented trough structure spaced apart along the bottom of the water receiving tray 10, and the support frame 30 is inserted into the clip-on structure 12. The support frame 30 can be fixed in a horizontal plane through the multi-segment trough structure so that the fin heat exchanger is fixed in the horizontal direction relative to the water receiving tray 10. At the same time, condensed water can be discharged to the outside of the clip-on structure 12 through the gap between the trough structures.

[0058] Furthermore, in some embodiments, the fin heat exchanger 20 further includes a mounting plate 26, one end of which is fixedly connected to the fin heat exchanger 20 and the other end of which is fixedly connected to the support frame 30, thereby securing the support frame 30 to the fin heat exchanger 20. Specifically, the mounting plate 26 includes a first mounting portion 262 and a second mounting portion 264, with the first mounting portion 262 being fixedly disposed within the interior of the fin heat exchanger 20. Furthermore, the first mounting portion 262 defines at least one through-hole 263, through which the internal piping of the fin heat exchanger 20 passes, thereby connecting the mounting plate 26 to the internal piping. In other embodiments, the first mounting portion 262 is provided with a slot, which is used to engage with an internal piping.

[0059] Furthermore, a mounting hole 265 is provided on the second mounting portion 264 of the mounting plate 26, and at least one positioning hole 342 corresponding to the mounting hole 265 is provided on the support plate 32 or the enclosure 34 of the support frame 30, and the positioning hole 342 and the mounting hole 265 are fixed by a locking member, thereby fixing the mounting plate 26 and the enclosure 34.

[0060] Specifically, the fin heat exchanger 20 is a multi-angle fin heat exchanger. The fin heat exchanger 20 includes at least one curved section and may also include at least one straight section. It is understood that the fin heat exchanger 20 is a curved fin heat exchanger obtained by any combination of several straight sections and several curved sections. Specific shapes may include L-shaped fin heat exchangers, U-shaped fin heat exchangers, annular fin heat exchangers, and the like.

[0061] See also Figure 3-7 As an example, in this embodiment, the fin heat exchanger 20 is configured as a plurality of straight sections and bent sections, which increases the total length of the fin heat exchanger in the same space, thereby increasing the total heat exchange area, improving space utilization and heat exchange capacity, and facilitating the layout and installation of the heat pump.

[0062] As an example, in this embodiment, the fin heat exchanger 20 includes a first straight section 221, a first bent section 222, a second straight section 223, a second bent section 224, a third straight section 225, a third bent section 226, and a fourth straight section 227, which are connected in sequence. Furthermore, the support frame 30 is in the shape of an elongated strip, and each straight section of the fin heat exchanger 20 is connected to a support frame 30. The clamping structure 12 is provided with four positioning blocks, which correspond to the four support frames 30 respectively. The support frames 30 are clamped with the positioning blocks, thereby assembling the fin heat exchanger 20 above the water receiving tray 10. The positioning blocks and the water receiving tray 10 can be fixedly connected by screws for easy installation or removal; they can also be fixedly connected by welding to improve the connection stability.

[0063] By way of example, in this embodiment, the two ends of each straight section are respectively connected to the first mounting portion 262 of a mounting plate 26, and the second mounting portion 264 of the mounting plate 26 is connected to the corresponding end of the support frame 30. More specifically, the panels along the length of the support frame 30 are defined as long panels 36. The end panels 362 of the long panels 36, located at both ends in the length direction, each have at least one positioning hole 342 defined therein. The positioning hole is positioned directly opposite the mounting hole. The second mounting portion 264 is secured to the end panels 362 by locking a locking member in the positioning hole, thereby achieving a fixed connection between the support frame 30 and the fin heat exchanger 20 and facilitating installation or removal.

[0064] In other embodiments, the second mounting portion 264 is fixed to the support plate 32. Specifically, the first mounting portion 262 and the second mounting portion 264 are arranged perpendicularly. The support plate 32 of the support frame 30 defines at least one positioning hole, which is arranged directly opposite the mounting hole. A locking member is locked in the positioning hole to secure the second mounting portion 264 to the support plate 32, thereby securing the support frame 30 and the mounting plate 26. Preferably, the second mounting portion 264 at least partially avoids the water leakage hole 322.

[0065] In some other embodiments, the support frame 30 and the fin heat exchanger 20 may be fixedly connected by welding, or directly locked by a locking member.

[0066] In this embodiment, the fin heat exchanger 20 further includes two end plates 24. By providing the end plates 24, the horizontal displacement of the fin heat exchanger during transportation and use is limited, thereby playing a certain protective role in preventing the fin heat exchanger 20 from being worn.

[0067] See also Figure 8 In some other embodiments, the support frame 30 is an integrated structure continuously provided along the bottom edge of the fin heat exchanger 20, which can support the fin heat exchanger more stably.

[0068] In some embodiments, the support frame 30 is a sheet metal structure. Sheet metal is light in weight, high in strength, and low in cost. Sheet metal also has conductive properties and can be used for electromagnetic shielding.

[0069] See also Figure 4 Furthermore, a water receiving area is formed on the upper surface of the water receiving pan 10 through a water retaining strip 18. The clamping structure 12 and the support frame 30 are arranged in the water receiving area to prevent condensed water from flowing into the space enclosed by the fin heat exchanger, so that the condensed water is discharged to the space outside the fin heat exchanger. A drain port 14 is also provided in the water receiving area, and a drain pipe 16 is provided at the bottom of the drain port 14 so that the condensed water on the surface of the water receiving pan 10 can be discharged through the drain pipe 16, preventing the condensed water from being retained on the water receiving pan 10 and causing ice or overflowing everywhere. Preferably, the drain port 14 is arranged below the support frame 30, so that the condensed water can enter the drain port 14 more quickly from the leakage hole 322, so that it can be discharged in time.

[0070] See also Figure 9-11 Furthermore, in some embodiments, an insulation groove 19 is provided on the lower surface of the water receiving area, and an insulation layer is provided in the insulation groove 19. As an example, the insulation layer is a sponge, which is light in weight, low in cost, has a good insulation effect, and is easy to obtain. By providing the insulation groove 19, the heat exchange between the condensed water collected in the water receiving tray 10 and the parts and air below the water receiving tray 10 is reduced, and the condensed water generated in the shell due to the cold bridge phenomenon between the water receiving tray 10 and the shell is reduced, while preventing the water receiving tray 10 from cracking or breaking. In other embodiments, the insulation groove can be filled with other foam insulation materials.

[0071] In one embodiment, the water receiving tray 10 is an integrated water receiving tray 10, thereby reducing the screw connection process and the assembly process. It is only necessary to snap the integrated water receiving tray 10 to the support frame 30 and connect the water receiving tray 10 to the drain pipe 16. While improving the assembly efficiency, it also improves the sealing of the water receiving tray 10 and avoids the impact of water leakage from the water receiving tray 10 on other parts of the device.

[0072] The present invention further provides a heat pump comprising the above-mentioned fixing structure of the fin heat exchanger. The fixing structure of the fin heat exchanger in this embodiment can have the same structure and achieve the same effect as the fixing structure of the fin heat exchanger in the above-mentioned embodiment, and will not be described in detail in this embodiment.

[0073] Compared with the existing technology, the beneficial effects of the technical solution of the utility model are as follows:

[0074] (1) By fixing the support frame to the fin heat exchanger, the fin dislocation of the multi-angle fin heat exchanger due to deformation is avoided, which affects the appearance;

[0075] (2) The multi-angle fin heat exchanger and the water tray can be quickly assembled and positioned by the support frame and the clamping structure in the horizontal direction;

[0076] (3) By setting leakage holes and cutouts on the support frame, the condensed water can be diverted so that the condensed water can be discharged quickly;

[0077] (4) By setting the snap-fit ​​structure at intervals, it is prevented from blocking the leakage holes and cutouts, thereby affecting the drainage of condensate;

[0078] (5) A water receiving area is formed by setting a water retaining strip on the upper surface of the water receiving tray to prevent condensed water from flowing into the space enclosed by the fin heat exchanger, which is more conducive to the discharge of condensed water.

[0079] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous modifications and improvements without departing from the concept of the present invention, and the present invention is intended to encompass such modifications and variations.
