Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and mainly to an air conditioner. Background Technology

[0002] An air conditioner is a device used to regulate indoor air temperature, humidity, airflow speed, and air cleanliness. It is widely used in homes, offices, commercial spaces, and industrial environments. Its basic principle is to transfer heat through the circulation of refrigerant, utilizing the physical processes of evaporation (absorbing heat) and condensation (releasing heat), thereby achieving a cooling or heating effect. With technological advancements, air conditioners not only possess cooling and heating functions but also integrate dehumidification, air purification, and other functions, becoming an indispensable appliance in modern life.

[0003] Generally, the heat exchanger of a portable air conditioner includes a first heat exchange section and a second heat exchange section, which are spaced apart to accommodate a water pump. The two ends of the first and second heat exchange sections are connected together by end plates.

[0004] However, since the end plates are mainly fixed with screws, the end plates used at both ends of the condenser are not interchangeable, which increases the cost of installation materials and management, and also affects installation efficiency and makes it difficult to install quickly. Utility Model Content

[0005] In view of the problem that the end plates used to install the heat exchanger are not universal in the existing technology, an air conditioner is provided.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] One aspect of this application provides an air conditioner, including a housing configured as the outer shell of the air conditioner; a heat exchanger disposed within the housing, the heat exchanger having two laterally opposite ends, namely a first end and a second end, the heat exchanger comprising: a first heat exchange portion extending from the first end to the second end; a second heat exchange portion extending from the first end to the second end and arranged laterally opposite to the first heat exchange portion; two first end plates, respectively disposed at the ends of the first heat exchange portion corresponding to the first end and the second end; two second end plates, respectively disposed at the ends of the second heat exchange portion corresponding to the first end and the second end; the first end plates and the second end plates are connected at a gap between the first heat exchange portion and the second heat exchange portion; the area of ​​the first end plate connected to the second end plate is provided with spaced-apart first connecting holes and first flanges. Holes; the first flanged hole protrudes from the side wall of the first end plate facing the first end; the distance between the first connecting hole and the first flanged hole is a first distance; the area of ​​the second end plate connected to the first end plate is provided with a second connecting hole and a second flanged hole arranged at intervals; the second flanged hole protrudes from the side wall of the second end plate facing the second end; the distance between the second connecting hole and the second flanged hole is a second distance; the first distance and the second distance are different; at the first end, the first connecting hole and the second flanged hole are arranged correspondingly and communicate with each other, the first flanged hole is blocked by the second end plate, and the second connecting hole is blocked by the first end plate; at the second end, the first flanged hole and the second connecting hole are arranged correspondingly and communicate with each other, the first connecting hole is blocked by the second end plate, and the second flanged hole is blocked by the first end plate.

[0008] The above technical solution has the following advantages or beneficial effects: By providing a first connecting hole and a first flanged hole on the first end plate, and a second connecting hole and a second flanged hole on the second end plate, when the first connecting hole and the second flanged hole are correspondingly connected, a connector can be inserted into the first connecting hole and the second flanged hole, thereby connecting the first end plate and the second end plate at one end of the heat exchanger together. When the second connecting hole and the first flanged hole are correspondingly connected, a connector can be inserted into the second connecting hole and the first flanged hole, thereby connecting the first end plate and the second end plate at the other end of the heat exchanger together. Furthermore, by setting the first distance and the second distance to different distances, when connecting the first heat exchange section and the second heat exchange section at opposite ends of the heat exchanger, the first end plate or the second end plate on one side can be staggered, so that the corresponding connecting hole and the flanged hole are correspondingly connected, allowing the same first end plate and second end plate to be used to connect and fix both ends of the heat exchanger. Furthermore, since the first and second distances are set to different distances, when one hole in the first end plate and one hole in the second end plate are connected, the other hole in the first end plate and the other hole in the second end plate can be blocked. This avoids the need to use end plates with different structures at both ends of the heat exchanger, as is required in traditional designs. Using the same first and second end plates at both ends of the heat exchanger not only makes the end plate installation more standardized, but the universal first and second end plates also reduce the complexity for manufacturers in managing multiple materials during production, simplifying material procurement and production processes, saving manpower and time, and improving installation and production efficiency.

[0009] In some embodiments of this application, an air conditioner is provided, wherein the first connecting hole and the first flange hole are arranged vertically at intervals along the height direction of the first end plate; and the second connecting hole and the second flange hole are arranged vertically at intervals along the height direction of the second end plate.

[0010] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: by providing a first connecting hole and a first flange hole at intervals in the height direction of the first end plate, and providing a second connecting hole and a second flange hole at intervals in the height direction of the second end plate, the height direction of the heat exchanger can be fully utilized. By setting the first end plate of the first end to be vertically offset relative to the first end plate of the second end, or setting the second end plate of the first end to be vertically offset relative to the second end plate of the second end, the first connecting hole and the second flange hole of one end are arranged and connected accordingly, and the second connecting hole and the first flange hole of the other end are arranged and connected accordingly, so that the first heat exchanger and the second heat exchanger are fixed at both ends using the same first end plate and second end plate.

[0013] In some embodiments of this application, an air conditioner is provided in which the misalignment distance between the two second end plate positions in the height direction is the same as the difference between the first distance and the second distance.

[0014] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: the misalignment distance of the two second end plates in the height direction is the same as the difference between the first distance and the second distance. When the first end plate of one end is misaligned with the first end plate of the other end according to the difference between the first distance and the second distance, or when the second end plate of one end is misaligned with the second end plate of the other end according to the difference between the first distance and the second distance, the first connecting hole and the second flange hole of one end can be arranged and connected accordingly, and the first flange hole and the second connecting hole of the other end can be arranged and connected accordingly.

[0015] In some embodiments of this application, an air conditioner is provided, wherein the first heat exchange section includes a plurality of laterally extending first heat dissipation pipes, the plurality of first heat dissipation pipes being arranged sequentially at intervals along the height direction according to a first spacing; the second heat exchange section includes a plurality of laterally extending second heat dissipation pipes, the plurality of second heat dissipation pipes being arranged sequentially at intervals along the height direction according to a second spacing; the difference between the first distance and the second distance is the same as the first spacing or the second spacing.

[0016] Another technical solution described above has the following advantages or beneficial effects: Multiple first heat dissipation pipes can be correspondingly inserted into the first through holes, thereby improving the connection stability between the first end plate and the first heat exchange section. Multiple second heat dissipation pipes can correspondingly be inserted into the second through holes, thereby improving the connection stability between the second end plate and the second heat exchange section. Furthermore, the difference between the first distance and the second distance can be the same as the first spacing. When the operator installs the first end plate and the second end plate at the other end of the heat exchanger, it is only necessary to offset the first end plate from the first end plate at the other end in the height direction by the installation position of one heat dissipation pipe. This further simplifies the installation process and improves installation efficiency.

[0017] In some embodiments of this application, an air conditioner is provided, wherein a slot is provided on the side of the first end plate facing the second heat exchange section; a hook is provided on the side wall of the second end plate facing the first end, and the hook engages with the slot.

[0018] Another technical solution described above has the following advantages or beneficial effects: the first end plate and the second end plate can be pre-fixed through the cooperation of the slot and the hook. During installation, by engaging the slot and the hook, the first end plate and the second end plate can be pre-connected before the connector is driven in, which can improve installation efficiency and facilitate operation. Furthermore, the first end plate and the second end plate are not only fixed by the connector, but also by engaging the slot and the hook, further improving the stable connection between the first end plate and the second end plate.

[0019] In some embodiments of this application, an air conditioner is provided, wherein the card slot includes a first card slot and a second card slot, the first card slot and the second card slot are arranged at intervals along the height direction on a first end plate, and the height difference between the first card slot and the second card slot is the same as the difference between the first distance and the second distance; at the first end, the hook portion engages with the first card slot; at the second end, the hook portion engages with the second card slot.

[0020] Another technical solution described above has the following advantages or beneficial effects: by making the height difference between the first and second slots the same as the difference between the first and second distances, the hook portion can be engaged with corresponding slots at different heights. Specifically, when the second end plate is offset in height between the first and second ends, the hook portion at the first end can engage with the first slot, and the hook portion at the second end can engage with the second slot, thereby improving the installation flexibility and adaptability of the first and second end plates.

[0021] In some embodiments of this application, an air conditioner is provided, wherein a first end plate has a first flange protruding from the side wall facing the first end, the first flange being annular in shape, and a first flange hole being formed within the annular first flange, the first flange hole being a threaded hole; a second end plate has a second flange protruding from the side wall facing the second end, the second flange being annular in shape, and a second flange hole being formed within the annular second flange, the second flange hole being a threaded hole.

[0022] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: The protrusion has a first flange portion with a threaded hole inside, allowing the first flange hole to form a connection space for the connector. The protrusion also has a second flange portion with a threaded hole inside, allowing the second flange hole to form a connection space for the connector. By having the first end plate have a first flange portion protruding from the side wall facing the first end, and the second end plate have a second flange portion protruding from the side wall facing the second end, at the first end of the heat exchanger, the connector can be sequentially inserted into the first connection hole and the second flange hole; at the second end of the heat exchanger, the connector can be sequentially inserted into the first flange hole and the second connection hole, thereby achieving the use of the same first end plate at both the first and second ends of the heat exchanger, and also the use of the same second end plate at both the first and second ends of the heat exchanger.

[0023] In some embodiments of this application, an air conditioner is provided, wherein a first mark is provided on the side wall of the first end plate facing the first end, the first mark is disposed adjacent to the first connection hole, and the first mark is used to indicate the connection position of the connector connecting the first end plate and the second end plate.

[0024] Another technical solution described above has the following advantages or beneficial effects: By providing a first mark on the side wall of the first end plate facing the first end, and the first mark being adjacent to the first connecting hole, the installer can quickly and accurately locate the connection position during installation on one side of the first end, and then pass the connector through the first connecting hole and the second flange hole in sequence, achieving rapid installation of the first end of the heat exchanger. Furthermore, during installation, the installer can use the first mark to confirm the placement and orientation of the connectors (such as screws, bolts, etc.), thereby avoiding incorrect or missing connections, which greatly improves installation efficiency and accuracy.

[0025] In some embodiments of this application, an air conditioner is provided, wherein a second mark is provided on the side wall of the second end plate facing the second end, the second mark is disposed adjacent to the second flange hole, and the second mark is used to indicate the connection position of the connector connecting the first end plate and the second end plate.

[0026] Another technical solution described above has the following advantages or beneficial effects: By providing a second mark on the side wall of the second end plate facing the second end, and the second mark being adjacent to the second flange hole, installers can quickly and accurately locate the connection position during installation on one side of the second end. This allows them to sequentially pass the connectors through the second connection hole and the first flange hole, achieving rapid installation of the second end of the heat exchanger. Furthermore, during installation, installers can use the second mark to confirm the placement and orientation of connectors (such as screws and bolts), thus avoiding incorrect or missing connections and significantly improving installation efficiency and accuracy.

[0027] In some embodiments of this application, an air conditioner is provided, the air conditioner further including a water receiving tray, the water receiving tray having a water receiving groove, the first heat exchange part and the second heat exchange part being installed in the water receiving tray and disposed above the water receiving groove; the water receiving tray is provided with a water-pumping wheel, the water-pumping wheel being rotatably disposed in the water receiving groove and located in the interval area between the first heat exchange part and the second heat exchange part; the water receiving tray is provided with a water-pumping motor, the water-pumping motor being disposed outside the water receiving groove, the water-pumping motor being drively connected to the water-pumping wheel to drive the water-pumping wheel to rotate.

[0028] Another technical solution described above has the following advantages or beneficial effects: the water collection tray can be used to collect condensate from the air conditioner. When the heat exchanger is configured as a condenser, placing the first and second heat exchange sections above the water collection tray facilitates cooling of the heat exchanger. By installing a water agitator in the water collection tray, driven by a water-discharging motor, the rotation of the agitator not only agitates the condensate but also promotes airflow around the heat exchanger, enhancing heat exchange between the air and the heat exchanger. The agitation by the water agitator forms a water curtain or mist, increasing the contact area between the air and the condensate, thereby improving heat exchange efficiency.

[0055] The air conditioner in the embodiments of the present invention can be a floor-standing air conditioner. The following uses a floor-standing air conditioner as an example to describe in detail the improved technical solution of the air conditioner in the embodiments of the invention.

[0056] Figure 1 This is a schematic diagram of an air conditioner according to an embodiment of this application.

[0057] like Figure 1 As shown, in some embodiments, the air conditioner may include a housing 1. The housing 1 may be configured as the outer shell of the air conditioner. The housing 1 may have an internal receiving space. The housing 1 may have a hollow structure, such as a cuboid. It should be noted that the housing 1 may form the outer shell of the air conditioner. The housing 1 may have other shapes of hollow housing 1 structures.

[0058] Figure 2 for Figure 1 Schematic diagram of the intermediate heat exchanger; Figure 3 This is a schematic diagram of the internal structure of an air conditioner;

[0059] like Figure 2 As shown, in some embodiments, the air conditioner may include a heat exchanger 2. The heat exchanger 2 may be disposed within the housing 1. The heat exchanger 2 may exchange heat with indoor air or outdoor air.

[0060] like Figure 3 As shown, in some embodiments, heat exchanger 2 may include an outdoor heat exchanger 210 and an indoor heat exchanger 220.

[0061] like Figure 3 As shown, in some embodiments, the air conditioner may include a refrigerant circulation loop. The refrigerant circulation loop may include a compressor 200, an outdoor heat exchanger 210, and an indoor heat exchanger 220 connected end-to-end. The refrigerant circulates within the refrigerant circulation loop formed by the compressor 200, the outdoor heat exchanger 210, and the indoor heat exchanger 220. During the refrigerant circulation process, the outdoor heat exchanger 210 and the indoor heat exchanger 220 can respectively function as a condenser and an evaporator, allowing the refrigerant to absorb heat through evaporation in the evaporator and release heat through condensation in the condenser, thereby enabling the air conditioner to perform either a cooling cycle or a heating cycle.

[0062] Specifically, in the refrigeration cycle, the outdoor heat exchanger 210 can act as a condenser, and the indoor heat exchanger 220 can act as an evaporator. In the heating cycle, the outdoor heat exchanger 210 can act as an evaporator, and the indoor heat exchanger 220 can act as a condenser.

[0063] It should be noted that both the refrigeration and heating cycles involve a series of processes, including compression, condensation, expansion, and evaporation, and the supply of refrigerant to the conditioned and heat-exchanged air.

[0064] Compressor 200 is used to compress refrigerant gas and discharge the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser.

[0065] The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0066] The evaporator evaporates the expanded refrigerant and returns the refrigerant gas, now at a low temperature and low pressure, to the compressor 200. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the surrounding environment.

[0067] Throughout the cycle, the air conditioner can regulate the temperature of the indoor space, improve the comfort of the indoor space, and enhance the user experience.

[0068] like Figure 3 As shown, in some embodiments, the air conditioner may include an outdoor fan assembly 230. The outdoor fan assembly 230 may be arranged opposite to the outdoor heat exchanger 210. The outdoor fan assembly 230 can be used to introduce outdoor air into the casing to exchange heat with the outdoor heat exchanger 210, forming a heat exchange airflow.

[0069] For example, during the cooling cycle, the outdoor heat exchanger 210 acts as a condenser, and the outdoor fan assembly 230 can draw in outside air and blow it onto the outdoor heat exchanger 210 to dissipate heat and lower its temperature. During the heating cycle, the outdoor heat exchanger 210 acts as an evaporator, and the outdoor fan assembly 230 can draw in outside air and blow it onto the outdoor heat exchanger 210 to raise its temperature.

[0070] like Figure 3 As shown, in some embodiments, the air conditioner may include an indoor fan assembly 240. The indoor fan assembly 240 may be arranged opposite to the indoor heat exchanger 220. The indoor fan assembly 240 can be used to introduce indoor air into the casing to exchange heat with the indoor heat exchanger 220, forming a heat exchange airflow.

[0071] For example, during the refrigeration cycle, the indoor heat exchanger 220 acts as an evaporator, and the indoor fan assembly 240 can draw indoor air from outside the casing and blow it towards the indoor heat exchanger 220 to exchange heat with it, thereby reducing the temperature of the air flowing through the indoor heat exchanger 220 and blowing the cooled air back into the room to lower the indoor air temperature.

[0072] For example, during the heating cycle, the indoor heat exchanger 220 acts as a condenser, and the outdoor fan assembly 230 can draw indoor air from outside the casing and blow it towards the indoor heat exchanger 220 to exchange heat with it, raising the temperature of the air flowing through the indoor heat exchanger 220, and then blowing the heated air back into the room to raise the indoor air temperature.

[0073] like Figure 3As shown, in some embodiments, the compressor 200, outdoor heat exchanger 210, outdoor fan assembly 230, indoor heat exchanger 220, and indoor fan assembly 240 can be respectively disposed in the receiving space 101 inside the casing 1. In this way, the casing can cover and protect them, preventing the erosion of foreign objects or the impact of external forces from causing structural damage, thereby improving the structural reliability of the air conditioner and ensuring that the air conditioner can work normally.

[0074] In some embodiments, the internal accommodating space 101 of the casing 1 may include three sub-spaces. These three sub-spaces are, from bottom to top, a first sub-space 110, a second sub-space 120, and a third sub-space 130. The compressor 200 may be disposed in the first sub-space 110. The outdoor heat exchanger 210 and the outdoor fan assembly 230 may be disposed in the second sub-space 120. The indoor heat exchanger 220 and the indoor fan assembly 240 may be disposed in the third sub-space 130. Thus, by using three layers of sub-spaces from bottom to top, components such as the compressor 200, the outdoor heat exchanger 210, the outdoor fan assembly 230, the indoor heat exchanger 220, and the indoor fan assembly 240 can be distributed at different heights within the casing 1, which helps to increase the overall height of the air conditioner, reduce its width and thickness, and minimize the space occupied by the air conditioner in the usage area.

[0075] Figure 4 for Figure 2 A schematic diagram of the first end; Figure 5 for Figure 2 A schematic diagram of the second end.

[0076] like Figure 2 and Figure 4 As shown, in some embodiments, the two opposite ends of the heat exchanger 2 in the lateral direction are a first end 201 and a second end 202, respectively. The heat exchanger 2 may include a first heat exchange section 21. The first heat exchange section 21 may extend from the first end 201 to the second end 202.

[0077] like Figure 2 and Figure 4 As shown, in some embodiments, the heat exchanger 2 may include a second heat exchange section 22. The second heat exchange section 22 may extend from the first end 201 to the second end 202. The second heat exchange section 22 may be arranged laterally opposite to the first heat exchange section 21.

[0078] like Figure 2 As shown, the first direction A1 is defined by the two opposite ends of the heat exchanger 2 in the lateral direction, and the two ends of the heat exchanger 2 in the first direction are the first end 201 and the second end 202, respectively. A second heat exchange section 22 is spaced apart on one side of the first heat exchange section 21, and the direction in which the second heat exchange section 22 is spaced apart from the first heat exchange section 21 is defined as the second direction A2. The first direction A1 can be perpendicular to the second direction A2.

[0079] Specifically, when the heat exchanger 2 is configured as an indoor heat exchanger, the heat exchanger 2 is vertically installed inside the air conditioner. Both the first heat exchange section 21 and the second heat exchange section 22 are vertically installed inside the air conditioner. The first heat exchange section 21 can be vertically installed on one side of the second heat exchange section 22. Moreover, the arrangement direction of the two ends of the first heat exchange section 21 in the horizontal direction is the same as the arrangement direction of the two ends of the second heat exchange section 22 in the horizontal direction.

[0080] like Figure 4 and Figure 5 As shown, in some embodiments, the heat exchanger 2 may include a first end plate 23. Two first end plates 23 may be provided. The two first end plates 23 may be respectively provided at the ends of corresponding first ends 201 and second ends 202 of the first heat exchange section 21. Specifically, one first end plate 23 is provided on the end of the first end 201 of the first heat exchange section 21, and the other first end plate 23 is provided on the end of the second end 202 of the first heat exchange section 21. The first end plates 23 are used to connect the first heat exchange section 21 and the second heat exchange section 22.

[0081] like Figure 4 and Figure 5 As shown, in some embodiments, the heat exchanger 2 may include a second end plate 24. Two second end plates 24 may be provided. The two second end plates 24 may be respectively provided at the ends of the corresponding first ends 201 and second ends 202 of the second heat exchange section 22. Specifically, one second end plate 24 is provided at the end of the first end 201 of the second heat exchange section 22, and the other second end plate 24 is provided at the end of the second end 202 of the first heat exchange section 21. The second end plates 24 are used to connect the first heat exchange section 21 and the second heat exchange section 22.

[0082] like Figure 4 As shown, in some embodiments, the first end plate 23 and the second end plate 24 can be connected at the interval 203 between the first heat exchange section 21 and the second heat exchange section 22. In this way, the first end plate 23 and the second end plate 24 located on both sides of the heat exchanger 2 can use the interval 203 between the first heat exchange section 21 and the second heat exchange section 22 as a connection area, avoiding interference between the connecting parts (not shown in the figure) between the first heat exchange section 21 and the second heat exchange section 22.

[0083] Figure 6 for Figure 4 An exploded view; Figure 7 for Figure 4 A magnified view of part A.

[0084] like Figure 6 and Figure 7As shown, in some embodiments, the area of ​​the first end plate 23 connected to the second end plate 24 may be provided with a first connecting hole 204 and a first flange hole 205 arranged at intervals. The first flange hole 205 may protrude from the side wall of the first end plate 23 facing the first end 201. The first connecting hole 204 and the first flange hole 205 are both located in the interval 203 between the first heat exchange portion 21 and the second heat exchange portion 22 of the first end plate 23. By protruding the first flange hole 205 from the first end plate 23, a space for accommodating a connector can be formed within the first flange hole 205.

[0085] In some embodiments, the connector may be a screw, bolt, etc.

[0086] Figure 8 for Figure 5 An exploded view; Figure 9 for Figure 5 A magnified view of section B.

[0087] like Figure 8 and Figure 9 As shown, in some embodiments, the area of ​​the second end plate 24 connected to the first end plate 23 may be provided with spaced-apart second connecting holes 206 and second flanged holes 207. The second connecting holes 206 and second flanged holes 207 are both located in the spaced region 203 of the second end plate 24 corresponding to the first heat exchange portion 21 and the second heat exchange portion 22. The second flanged hole 207 may protrude from the sidewall of the second end plate 24 facing the second end 202. By protruding the second flanged hole 207 from the second end plate 24, a space for accommodating a connector can be formed within the second flanged hole 207.

[0088] Specifically, such as Figure 6 and Figure 7 As shown, by providing a first connecting hole 204 and a first flanged hole 205 on the first end plate 23, and a second connecting hole 206 and a second flanged hole 207 on the second end plate 24, when the first connecting hole 204 and the second flanged hole 207 are correspondingly connected, the connector can be inserted into the first connecting hole 204 and the second flanged hole 207, thereby connecting the first end plate 23 and the second end plate 24 together. Figure 7 and Figure 8 As shown, when the second connecting hole 206 is connected to the first flange hole 205, the connector can be inserted into the second connecting hole 206 and the first flange hole 205, thereby connecting the first end plate 23 and the second end plate 24 together.

[0089] Furthermore, since the installation direction of the connectors is from the outside to the inside, the installation directions of the connectors at the first end 201 and the second end 202 of the heat exchanger 2 are opposite. The first flanged hole 205 protrudes from the side wall of the first end plate 23 facing the first end 201, and the second flanged hole 207 protrudes from the side wall of the second end plate 24 facing the second end 202. That is, the first flanged hole 205 of the first end plate 23 and the second flanged hole 207 of the second end plate 24 are oriented in different directions. In this way, for the installation at the first end 201, the second flanged hole 207 facing the second end 202 can be connected to the first connecting hole 204, thus providing the correct installation space for the connector. Similarly, for the installation at the second end 202, the first flanged hole 205 facing the first end 201 can be connected to the second connecting hole 206, providing the correct installation space for the connector. This provides a structural basis for the installation of the heat exchanger 2 at its opposite ends.

[0090] Figure 10 This is a schematic diagram showing the orientation of the first end plate and the second end plate toward the first end.

[0091] It should be noted that, Figure 10 In the diagram, L1 represents the first distance and L2 represents the second distance.

[0092] like Figure 10 As shown, in some embodiments, the distance between the second connecting hole 206 and the second flanged hole 207 can be a second distance L2. The distance between the first connecting hole 204 and the first flanged hole 205 can be a first distance L1. The first distance L1 is different from the second distance L2. At the first end 201, the first connecting hole 204 and the second flanged hole 207 can be arranged correspondingly and communicate with each other. The first flanged hole 205 can be blocked by the second end plate 24. The second connecting hole 206 can be blocked by the first end plate 23. At the second end 202, the first flanged hole 205 and the second connecting hole 206 can be arranged correspondingly and communicate with each other. The first connecting hole 204 can be blocked by the second end plate 24. The second flanged hole 207 can be blocked by the first end plate 23.

[0093] By setting the first distance L1 and the second distance L2 to different distances, the first end plate 23 or the second end plate 24 at one end can be misaligned with the corresponding end plate at the other end, thereby achieving the corresponding arrangement and communication between the first connecting hole 204 and the second flange hole 207 at the first end 201, and the corresponding arrangement and communication between the first flange hole 205 and the second connecting hole 206 at the second end 202.

[0094] Specifically, such as Figure 4 and Figure 7As shown, when installing the first end 201 of the heat exchanger 2, the first connecting hole 204 and the second flange hole 207 located on the first end 201 are correspondingly set. Since the first distance L1 and the second distance L2 are set to different distances, the first flange hole 205 is blocked by the second end plate 24, and the second connecting hole 206 is blocked by the first end plate 23. This can avoid connection errors by the staff during installation and also improve the efficiency of the installation process.

[0095] like Figure 5 and Figure 9 As shown, when installing the second end 202 of the heat exchanger 2, the second end plate 24 is offset at the opposite ends of the heat exchanger 2, while the position of the first end plate 23 remains unchanged, so that the second connecting hole 206 at the second end 202 corresponds to the first flange hole 205. Since the first distance L1 and the second distance L2 are set to different distances, the second flange hole 207 is blocked by the first end plate 23, and the first connecting hole 204 is blocked by the second end plate 24. This avoids connection errors during installation and improves installation efficiency. Furthermore, since the first end plate 23 used for both the first end 201 and the second end 202 is the same, the second end plate 24 is also the same, thereby improving the versatility of the end plates used in the heat exchanger 2, reducing production and manufacturing complexity, and eliminating the need to store and manage multiple models of end plates.

[0096] In existing heat exchangers 2, two heat exchange sections are typically spaced apart and connected by two end plates. The space created by the spacing is used to install heat dissipation devices. However, because the connection is made using screws or other fasteners, the fasteners need to be installed from the outside in, resulting in different end plates being used at the two ends of the heat exchanger 2.

[0097] In this technical solution, the first end plate 23 used at the first end 201 and the second end 202 of the heat exchanger 2 has the same structure, and the second end plate 24 used at the first end 201 and the second end 202 of the heat exchanger 2 also has the same structure. Both transverse ends of the heat exchanger 2 are connected via the first end plate 23 and the second end plate 24. Specifically, a first connecting hole 204 and a first flanged hole 205 are provided on the first end plate 23, and a second connecting hole 206 and a second flanged hole 207 are provided on the second end plate 24. When the first connecting hole 204 and the second flanged hole 207 are connected, a connector can pass through the first connecting hole 204 and the second flanged hole 207, thereby connecting the first end plate 23 and the second end plate 24 at one end of the heat exchanger 2. When the second connecting hole 206 and the first flanged hole 205 are connected, a connector can pass through the second connecting hole 206 and the first flanged hole 205, thereby connecting the first end plate 23 and the second end plate 24 at the other end of the heat exchanger 2.

[0098] Furthermore, by setting the first distance L1 and the second distance L2 to different distances, when connecting the first heat exchange section 21 and the second heat exchange section 22 at opposite ends of the heat exchanger 2, the first end plate 23 or the second end plate 24 on one side can be staggered so that the corresponding connecting holes and flange holes are connected, allowing the two ends of the heat exchanger 2 to be connected and fixed using the same first end plate 23 and second end plate 24 respectively. Moreover, since the first distance L1 and the second distance L2 are set to different distances, when one hole of the first end plate 23 and one hole of the second end plate 24 are connected, the other hole of the first end plate 23 and the other hole of the second end plate 24 can be blocked. Thus, when a water jet 31 is provided at the interval between the first heat exchange section 21 and the second heat exchange section 22, the water raised by the water jet 31 will not splash directly to the outside through the hole without a connecting member.

[0099] The technical solution of this embodiment can avoid the need to use end plates with different structures at both ends of the heat exchanger 2 in the traditional design. Using the same first end plate 23 and second end plate 24 at both ends of the heat exchanger 2 can not only make the end plate installation of the heat exchanger 2 more standardized, but also reduce the complexity of manufacturers having to manage multiple materials in the production process, simplify material procurement and production process, save manpower management time, and improve the efficiency of installation and production.

[0100] like Figure 10 As shown, in some embodiments, the first connecting hole 204 and the first flange hole 205 can be arranged vertically at intervals along the height direction A3 of the first end plate 23. The second connecting hole 206 and the second flange hole 207 can be arranged vertically at intervals along the height direction A3 of the second end plate 24.

[0101] It should be noted that the height of the first end plate 23 and the height of the second end plate 24 correspond to the height of the air conditioner. For example... Figure 5 and Figure 7As shown, by providing a first connecting hole 204 and a first flange hole 205 at intervals on the height direction A3 of the first end plate 23, and providing a second connecting hole 206 and a second flange hole 207 at intervals on the height direction of the second end plate 24, the height direction of the heat exchanger 2 can be fully utilized. By offsetting the first end plate 23 of the first end 201 with the first end plate 23 of the second end 202, or offsetting the second end plate 24 of the first end 201 with the second end plate 24 of the second end 202, the first connecting hole 204 and the second flange hole 207 at one end are arranged and connected, and the second connecting hole 206 and the first flange hole 205 at the other end are arranged and connected, so that the first heat exchange part 21 and the second heat exchange part 22 are fixed at both ends using the same first end plate 23 and second end plate 24.

[0102] On the other hand, given the limited internal space of the air conditioner, the vertically spaced connection holes and flange holes can make more effective use of the height space of the heat exchanger 2, making the heat exchanger 2 more compact and efficient.

[0103] Figure 11 for Figure 4 A schematic diagram of the first end plate; Figure 12 for Figure 11 A three-dimensional image.

[0104] like Figure 11 and Figure 12 As shown, in some embodiments, the first connecting hole 204 and the first flange hole 205 may be disposed at the upper end of the first end plate 23. The second connecting hole 206 and the second flange hole 207 may be disposed at the upper end of the second end plate 24.

[0105] like Figure 11 As shown, in some embodiments, two first connecting holes 204 and two first flanged holes 205 may be provided. One set of first connecting holes 204 and first flanged holes 205 may be provided near the upper end of the first end plate 23. The other set of first connecting holes 204 and first flanged holes 205 may be provided near the lower end of the first end plate 23.

[0106] Figure 13 for Figure 4 A schematic diagram of the second end plate; Figure 14 for Figure 13 A three-dimensional image.

[0107] like Figure 13 and Figure 14As shown, in some embodiments, two second connecting holes 206 and two second flanged holes 207 may be provided. One set of second connecting holes 206 and second flanged holes 207 may be provided near the upper end of the second end plate 24. The other set of second connecting holes 206 and second flanged holes 207 may be provided near the lower end of the second end plate 24.

[0108] In this way, by setting two sets of first connecting holes 204 and first flange holes 205, and two sets of second connecting holes 206 and second flange holes 207, the connection stability between the first heat exchange section 21 and the second heat exchange section 22 can be improved.

[0109] In some other embodiments, the first connecting hole 204 and the first flange hole 205 may be arranged at intervals along the width direction of the first end plate 23. The second connecting hole 206 and the second flange hole 207 may be arranged vertically at intervals along the width direction of the second end plate 24. It should be noted that the width direction of the first end plate 23 and the width direction of the second end plate 24 may refer to the second direction respectively.

[0110] like Figure 4 and Figure 5 As shown, in some embodiments, the two first end plates 23 may be located at the same height at both ends of the first heat exchange section 21. The two second end plates 24 may be located at different heights at both ends of the first heat exchange section 21, and the two second end plates 24 are staggered in the height direction.

[0111] Since the first end plate 23 is provided with a first connecting hole 204 and a first flange hole 205 at intervals in the height direction, and the second end plate 24 is provided with a second connecting hole 206 and a second flange hole 207 at intervals in the height direction, during the installation process, the heat exchanger 2 can be fixed at opposite ends by using the first end plate 23 at one end to the first end plate 23 at the other end, or by using the second end plate 24 at one end to the second end plate 24 at the other end.

[0112] In this embodiment, the first end plate 23 is positioned at the same height at both ends of the first heat exchange section 21, meaning the positions of the first end plate 23 at opposite ends of the first heat exchange section 21 are identical. Only the two second end plates 24 are positioned at different heights at both ends of the first heat exchange section 21. This allows the operator to easily connect the corresponding flanged holes and connecting holes by simply changing the installation position of one end plate during installation. This simplifies the installation process of the heat exchanger 2 and improves installation and production efficiency.

[0113] like Figure 4 and Figure 5As shown, in some embodiments, the heights of the first heat exchange section 21 and the second heat exchange section 22 can be the same. The height of the first end plate 23 can be designed to be the same as the height of the first heat exchange section 21, and the height of the second end plate 24 can be designed to be less than the height of the second heat exchange section 22. This not only facilitates the installation of the first end plate 23, but also ensures that when the second end plate 24 is installed in a staggered manner in the height direction, the upper and lower ends of the second end plate 24 will not exceed the upper and lower ends of the second heat exchange section 22, thus avoiding the second end plate 24 occupying space in the height direction of the air conditioner due to the staggered installation and maintaining the compact structure of the heat exchanger 2.

[0114] In some other embodiments, the two second end plates 24 may be located at the same height at both ends of the first heat exchange section 21. The two first end plates 23 may be located at different heights at both ends of the first heat exchange section 21, and the two first end plates 23 may be staggered in the height direction.

[0115] like Figure 10 As shown, in some embodiments, the difference between the misalignment distance of the two second end plates 24 in the height direction and the difference between the first distance L1 and the second distance L2 can be the same.

[0116] In this way, during the installation process, the offset distance of the two second end plates 24 in the height direction is the same as the difference between the first distance L1 and the second distance L2. When the first end plate 23 of one end is offset vertically relative to the first end plate 23 of the other end according to the difference between the first distance L1 and the second distance L2, or when the second end plate 24 of one end is offset vertically relative to the second end plate 24 of the other end according to the difference between the first distance L1 and the second distance L2, the first connecting hole 204 and the second flange hole 207 of one end can be arranged and connected accordingly, and the first flange hole 205 and the second connecting hole 206 of the other end can be arranged and connected accordingly. At the same time, the hole that does not have a connector is blocked by the other end plate.

[0117] like Figure 4 and Figure 5 As shown, in some embodiments, the first heat exchange section 21 may include a plurality of laterally extending first heat dissipation pipes 211. For example... Figure 9 As shown, multiple first heat dissipation pipes 211 can be arranged sequentially at intervals along the height direction according to a first spacing L3. The multiple first heat dissipation pipes 211 can improve the heat exchange efficiency between the first heat exchange section 21 and the airflow.

[0118] like Figure 11 and Figure 12As shown, in some embodiments, the first end plate 23 may be provided with a plurality of first through holes 209. The plurality of first through holes 209 may be spaced apart along the height direction of the first end plate 23. A plurality of first heat dissipation pipes 211 may be correspondingly inserted into the first through holes 209, thereby improving the connection stability between the first end plate 23 and the first heat exchange part 21.

[0119] It should be noted that, as Figure 9 In the figure, the spacing between the first heat dissipation pipes 211 can be considered as the spacing between the first through holes 209, and the spacing between the second heat dissipation pipes 221 can be considered as the spacing between the second through holes 210. For ease of understanding, the first spacing is represented by the spacing L3 between the first through holes 209, and the second spacing is represented by the spacing L4 between the second through holes 210.

[0120] like Figure 13 and Figure 14 As shown, in some embodiments, the second heat exchange section 22 may include a plurality of laterally extending second heat dissipation pipes 221. The plurality of second heat dissipation pipes 221 may be arranged sequentially at intervals along the height direction according to a second spacing L4. Part of the plurality of second heat dissipation pipes 221 may improve the heat exchange efficiency between the second heat exchange section 22 and the airflow.

[0121] like Figure 13 As shown, in some embodiments, the second end plate 24 may be provided with a plurality of second through holes 210. The plurality of second through holes 210 may be spaced apart along the height direction of the second end plate 24. A plurality of second heat dissipation pipes 221 may be correspondingly inserted into the second through holes 210, thereby improving the connection stability between the second end plate 24 and the second heat exchange section 22.

[0122] In some embodiments, the difference between the first distance L1 and the second distance L2 can be the same as the first spacing L3. Thus, when the operator installs the first end plate 23 and the second end plate 24 at the other end of the heat exchanger 2, it is only necessary to offset the first end plate 23 from the first end plate 23 at the other end in the height direction by the installation position of a heat dissipation pipe. This further simplifies the installation process and improves installation efficiency.

[0123] In some embodiments, the difference between the first distance L1 and the second distance L2 can be the same as the second spacing L4. Thus, when the operator installs the first end plate 23 and the second end plate 24 at the other end of the heat exchanger 2, it is only necessary to offset the second end plate 24 from the second end plate 24 at the same height by the installation position of a heat dissipation pipe. This further simplifies the installation process and improves installation efficiency.

[0124] like Figure 11 and Figure 7As shown, in some embodiments, one of the first end plate 23 and the second end plate 24 may be provided with a slot 208. The other of the first end plate 23 and the second end plate 24 may be provided with a hook portion 241. The hook portion 241 can engage with the slot 208.

[0125] The first end plate 23 and the second end plate 24 can be pre-fixed through the cooperation of the slot 208 and the hook portion 241. During installation, by engaging the slot 208 and the hook portion 241, the first end plate 23 and the second end plate 24 can be pre-connected before the connector is driven in, which can improve installation efficiency and facilitate operation. On the other hand, the first end plate 23 and the second end plate 24 can not only be fixed by the connector, but also by engaging the slot 208 and the hook portion 241, which further improves the stable connection between the first end plate 23 and the second end plate 24.

[0126] like Figure 11 As shown, in some embodiments, the side of the first end plate 23 facing the second heat exchange section 22 may be provided with a slot 208. The side wall of the second end plate 24 facing the first end 201 may be provided with a hook portion 241.

[0127] Specifically, at the first end 201 of the heat exchanger 2, the side wall of the second end plate 24 facing the first end 201 is provided with a hook portion 241. When the hook portion 241 is engaged in the slot 208, the first end plate 23 can be clamped between the hook portion 241 and the second end plate 24, improving the connection stability of the first end plate 23 and the second end plate 24 at the first end 201. At the second end 202 of the heat exchanger 2, when the hook portion 241 is engaged in the slot 208, the first end plate 23 can also be clamped between the hook portion 241 and the second end plate 24, thus improving the connection stability of the first end plate 23 and the second end plate 24 at the second end 202.

[0128] like Figure 11 As shown, in some embodiments, the card slot 208 may include a first card slot 2081 and a second card slot 2082. The first card slot 2081 and the second card slot 2082 may be arranged at intervals along the height direction on the first end plate 23. The height difference between the first card slot 2081 and the second card slot 2082 may be the same as the difference between a first distance L1 and a second distance L2. Figure 6 As shown, at the first end 201, the hook portion 241 can engage with the first slot 2081. Figure 9 As shown, at the second end 202, the hook portion 241 can engage with the second slot 2082.

[0129] Specifically, by making the height difference between the first slot 2081 and the second slot 2082 the same as the difference between the first distance L1 and the second distance L2, the hook portion 241 can be engaged with the corresponding slot 208 at different heights. Specifically, when the second end plate 24 is offset in height between the first end 201 and the second end 202, the hook portion 241 at the first end 201 can engage with the first slot 2081, and the hook portion 241 at the second end 202 can engage with the second slot 2082, thereby improving the installation flexibility and adaptability of the first end plate 23 and the second end plate 24.

[0130] In some other embodiments, the first end plate 23 has a slot 208 on the side facing the second heat exchange section 22, which can extend along the height direction. This also allows the hook portion 241 to have a corresponding slot 208 for engagement at different heights when the height positions of the second end plate 24 are staggered at both ends.

[0131] like Figure 12 As shown, in some embodiments, the sidewall of the first end plate 23 facing the first end 201 may have a protruding first flange portion 231. The first flange portion 231 may be annular. A first flange hole 205 may be formed within the annular first flange portion 231. The first flange hole 205 may be a threaded hole. The protruding first flange portion 231 with a threaded hole inside allows the first flange hole 205 to form a connection space for the connector.

[0132] like Figure 13 As shown, in some embodiments, the second end plate 24 has a second flange portion 242 protruding from the sidewall facing the second end 202. The second flange portion 242 is annular, and a second flange hole 207 is formed inside the annular second flange portion 242. The second flange hole 207 is a threaded hole. The protruding second flange portion 242 has a threaded hole inside, allowing the second flange hole 207 to form a connection space for the connector.

[0133] Specifically, since all connecting parts need to be installed from the outside in, the directions of the connecting holes at the first end 201 and the second end 202 are opposite. By providing a first flange 231 protruding from the sidewall of the first end plate 23 towards the first end 201, and a second flange 242 protruding from the sidewall of the second end plate 24 towards the second end 202, the connecting parts at the first end 201 of the heat exchanger 2 can be sequentially inserted into the first connecting hole 204 and the second flange hole 207, and at the second end 202 of the heat exchanger 2, the connecting parts can be sequentially inserted into the first flange hole 205 and the second connecting hole 206. This allows the same first end plate 23 to be used at both the first end 201 and the second end 202 of the heat exchanger 2, and the same second end plate 24 to be used at both ends.

[0134] like Figure 7 So and Figure 11 As shown, in some embodiments, the sidewall of the first end plate 23 facing the first end 201 may be provided with a first mark 232. The first mark and the first connecting hole 204 may be arranged adjacent to each other. The first mark 232 may be used to indicate the connection position of the connector connecting the first end plate 23 and the second end plate 24.

[0135] Specifically, on the first end 201, the first end plate 23 is located outside the second end plate 24, that is, the first end plate 23 is located on the side of the second end plate 24 facing the first end 201. During the installation of the first heat exchange section 21 and the second heat exchange section 22 of the first end 201, the first end plate 23 is positioned facing the operator. By providing a first mark 232 on the side wall of the first end plate 23 facing the first end 201, and by having the first mark adjacent to the first connecting hole 204, the installer can quickly and accurately locate the connection position during installation on one side of the first end 201, and then pass the connectors sequentially through the first connecting hole 204 and the second flange hole 207, thus achieving rapid installation of the first end 201 of the heat exchanger 2. Moreover, during installation, the installer can use the first mark 232 to confirm the placement and orientation of the connectors (such as screws, bolts, etc.), thereby avoiding incorrect or missing connections, which greatly improves installation efficiency and accuracy.

[0136] like Figure 7 So and Figure 11 As shown, in some embodiments, the sidewall of the first end plate 23 facing the first end 201 may be provided with a third mark 233. The third mark 233 may be used to indicate the location where the connector cannot be installed.

[0137] In some embodiments, the third mark 233 can be an "×" mark. It should be noted that the third mark 233 can be other prohibited marks, thereby reminding installers not to install connectors in the corresponding holes.

[0138] like Figure 9 So and Figure 13 As shown, in some embodiments, the sidewall of the second end plate 24 facing the second end 202 may be provided with a second mark 243. The second mark and the second flange hole 207 may be arranged adjacent to each other. The second mark 243 may be used to indicate the connection position of the connector connecting the first end plate 23 and the second end plate 24.

[0139] Specifically, on the second end 202, the second end plate 24 is located outside the first end plate 23, that is, the second end plate 24 is located on the side of the first end plate 23 facing the second end 202. During the installation of the first heat exchange section 21 and the second heat exchange section 22 of the second end 202, the second end plate 24 is positioned facing the operator. By providing a second mark 243 on the side wall of the second end plate 24 facing the second end 202, and by having the second mark adjacent to the second flange hole 207, the installer can quickly and accurately locate the connection position during installation on one side of the second end 202, and then pass the connectors sequentially through the second connection hole 206 and the first flange hole 205, thus achieving rapid installation of the second end 202 of the heat exchanger 2. Moreover, during installation, the installer can use the second mark 243 to confirm the placement and orientation of the connectors (such as screws, bolts, etc.), thereby avoiding incorrect or missing connections, which greatly improves installation efficiency and accuracy.

[0140] like Figure 9 So and Figure 13 As shown, in some embodiments, the sidewall of the second end plate 24 facing the second end 202 may be provided with a fourth mark 244. The fourth mark 244 may be disposed adjacent to the second flange hole 207. The fourth mark 244 may be used to indicate the location where a connector cannot be installed.

[0141] Specifically, on the second end 202 of the heat exchanger 2, a second flange 242 is provided protruding from the side wall of the second end plate 24 facing the second end 202. During the installation of the second end 202 of the heat exchanger 2, the connector cannot pass through the second flange hole 207. Therefore, by providing a fourth mark 244 at a position adjacent to the second flange hole 207, the installer can be alerted to avoid incorrect installation, thus improving installation accuracy and efficiency.

[0142] In some embodiments, the fourth mark 244 can be an "×" mark. It should be noted that the fourth mark 244 can be other prohibited marks, thereby reminding installers not to install connectors in the corresponding holes.

[0144] like Figure 15 and Figure 16 As shown, in some embodiments, the air conditioner may include a drip tray 3. The drip tray 3 may be provided with a water trough 301. A first heat exchange unit 21 and a second heat exchange unit 22 are installed in the drip tray 3 and are disposed above the water trough 301.

[0145] The water tray 3 can be used to collect condensate in the air conditioner. When the heat exchanger 2 is configured as a condenser, it is beneficial to cool the heat exchanger 2 by placing the first heat exchange section 21 and the second heat exchange section 22 above the water tray 301.

[0146] like Figure 15 and Figure 16 As shown, in some embodiments, the water receiving tray 3 may have a water agitator 31, which is rotatably disposed within the water receiving trough 301. The water agitator 31 may be located within the interval 203 between the first heat exchange section 21 and the second heat exchange section 22. The water receiving tray 3 may be equipped with a water agitator motor 32. The water agitator motor 32 may be disposed outside the water receiving trough 301. The water agitator motor 32 and the water agitator 31 may be connected in a transmission connection to drive the water agitator 31 to rotate.

[0147] Specifically, a water flow channel is formed in the interval 203 between the first heat exchange section 21 and the second heat exchange section 22, and a water jet 31 is correspondingly disposed at the lower end of the interval 203. In the cooling mode of the air conditioner, when the heat exchanger 3 acts as the outdoor heat exchanger, by placing the water collection tray 3 below the first heat exchange section 21 and the second heat exchange section 22, condensate will be generated on the surface of the heat exchanger during the heat exchange process. The condensate will flow to the water collection tray 3 under the influence of gravity. By arranging the water jet 31 and the water jet motor 32 on the water collection tray 3, and by having the water jet motor 32 drive the water jet 31 to rotate, the rotation of the water jet 31 can splash up the condensate in the water jet 31 and cool the surface of the heat exchanger. This achieves self-treatment of the water in the water collection tank 301 and also improves the heat exchange efficiency of the outdoor heat exchanger.

[0148] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of this application is limited only by the appended claims.
