Heat exchangers and air conditioners
[0001] This disclosure claims priority to Chinese patent application No. 202422936387.3, filed on November 28, 2024; Chinese patent application No. 202411732880.1, filed on November 28, 2024; and Chinese patent application No. 202423322119.9, filed on December 31, 2024, the entire contents of which are incorporated herein by reference. Technical Field
[0002] This disclosure relates to the field of air conditioning technology, and in particular to a heat exchanger and an air conditioner. Background Technology
[0003] Currently, the main types of outdoor heat exchanger fins used in air conditioners are corrugated fins and slotted fins. Slotted fins have a higher external convective heat transfer coefficient compared to corrugated fins due to their stronger ability to turbulent airflow. However, slotted fins are prone to water bridging under heating conditions, resulting in poor drainage performance and easy frost formation, which affects heating capacity. Therefore, for both cooling and heating units, manufacturers mainly use corrugated fins. Corrugated fins generally have transverse corrugations added to the fin surface, with the number of corrugations and their angle being key design parameters.
[0004] In related technologies, the presence of the bottom ring and bottom angle of the perforation in the corrugated sheet results in an incomplete corrugated shape, which not only loses part of the corrugated area but also weakens the heat exchange capacity of the corrugated sheet for the incoming airflow. Summary of the Invention
[0005] In a first aspect, in some embodiments, this disclosure proposes a heat exchanger, comprising: fins, the fins comprising a plurality of fin unit rows distributed in the width direction of the fins, each fin unit row comprising a plurality of fin units distributed along the length direction of the fins, each fin unit being provided with a tube hole, the tube holes in two adjacent fin unit rows being staggered; a heat exchange tube, the heat exchange tube passing through the tube hole, the heat exchange tube containing a refrigerant; the fin unit comprising: a flat region, the flat region being arranged circumferentially along the tube hole; and a corrugated region, the corrugated region surrounding the flat region and facing towards the thickness direction of the fin unit. The corrugated area protrudes to one side and includes a first corrugated segment, which includes a first inclined segment and a second inclined segment connected sequentially along the incoming flow direction. The first inclined segment is inclined relative to the second inclined segment. A transition area is obliquely connected between the flat area and the corrugated area, and the transition area intersects with the first inclined segment and the second inclined segment respectively. The maximum height at the intersection of the first inclined segment and the second inclined segment is H, and the minimum height at the intersection of the transition area and the first inclined segment is H1. H and H1 satisfy the relationship: H1≥1 / 3×H, and H and H1 satisfy the relationship: H1≤2 / 3×H.
[0006] In this disclosure, by setting up the heat exchanger, the corrugation height in front of the heat exchange tube can be reasonably controlled, which reduces the loss of heat exchange area on the first corrugated section and reduces the flow resistance of the incoming flow, thereby improving the overall heat exchange efficiency.
[0007] Secondly, in some embodiments, this disclosure provides an air conditioner, comprising: a heat exchanger, the heat exchanger comprising: fins, the fins comprising a plurality of fin unit rows distributed in the width direction of the fins, each fin unit row comprising a plurality of fin units distributed along the length direction of the fins, each fin unit being provided with a tube hole, the tube holes in two adjacent fin unit rows being staggered; a heat exchange tube, the heat exchange tube passing through the tube hole, the heat exchange tube containing refrigerant; the fin unit comprising: a flat region, the flat region being arranged circumferentially along the tube hole; and a corrugated region, the corrugated region being arranged around the flat region, the corrugated region facing the fins. One side of the unit protrudes in the thickness direction. The corrugated area includes a first corrugated segment, which includes a first inclined segment and a second inclined segment connected sequentially along the flow direction. The first inclined segment is inclined relative to the second inclined segment. A transition area is obliquely connected between the flat area and the corrugated area. The transition area intersects with the first inclined segment and the second inclined segment respectively. The maximum height at the intersection of the first inclined segment and the second inclined segment is H, and the minimum height at the intersection of the transition area and the first inclined segment is H1. H and H1 satisfy the relationship: H1≥1 / 3×H, and H and H1 satisfy the relationship: H1≤2 / 3×H.
[0008] Thirdly, in some embodiments, this disclosure proposes an air conditioner, comprising:
[0009] An air conditioner body, the air conditioner body having a first air inlet and a first air outlet;
[0010] A duct component, which is configured to be detachably connected to the air conditioner body, and when the air conditioner body is installed on the windowsill, the duct component is located on the indoor side of the windowsill;
[0011] The air duct component includes:
[0012] An air outlet duct is provided corresponding to the first air outlet, and the air outlet duct is used to connect the indoor side of the windowsill with the first air outlet;
[0013] An air inlet duct is provided, which is corresponding to the first air inlet, and is used to connect the indoor side of the windowsill with the first air inlet.
[0014] In this disclosure, the entire air conditioner unit is installed on the windowsill, with the ductwork located on the indoor side of the windowsill. The ductwork is detachably connected to the air conditioner unit. In summer, the ductwork connects the air conditioner unit and the indoor side of the windowsill, allowing for normal operation of the air conditioner. In winter, because the ductwork is detachably connected to the air conditioner unit, which is located on the outdoor side of the windowsill, the window on the windowsill can be completely closed without disassembling the entire air conditioner unit. This does not alter the overall structure of the air conditioner, meaning it does not affect its normal operation. In summer, there is no need to reinstall the air conditioner on the windowsill; simply reinstalling the ductwork onto the air conditioner unit achieves indoor insulation and sealing, improves ease of use, and enhances the user experience.
[0015] As can be seen, by setting up a detachable air duct component to connect with the air conditioner, this application can solve the problems of window space occupation, insufficient sealing and cumbersome disassembly and assembly caused by the installation method of the air conditioner while maintaining the price advantage and installation convenience of the air conditioner.

[0039] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

These terms are primarily for the purpose of better describing this disclosure and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.
[0041] Furthermore, the terms "installation," "setup," "equipped with," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection via an intermediate medium, or an internal connection between two devices, components, or components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances. In addition, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance or quantity of the indicated devices, components, or components. Unless otherwise stated, "a plurality of" means two or more.
[0042] In some embodiments of this disclosure, a heat exchanger is provided. Referring to FIG. 1, the heat exchanger 100 may include fins 1 and heat exchange tubes 2. The heat exchange tubes 2 can serve as a medium for heat exchange between the refrigerant and the outside air, and the refrigerant can flow inside them. For example, when the heat exchanger 100 is an evaporator, the refrigerant flowing in the heat exchange tubes 2 can be a low-temperature, low-pressure liquid; when the heat exchanger 100 is a condenser, the refrigerant flowing in the heat exchange tubes 2 can be a high-temperature, high-pressure gas. The fins 1 can be tightly attached to the outer surface of the heat exchange tubes 2, which can effectively increase the heat exchange contact area between the air and the heat exchange tubes 2, thereby accelerating the heat transfer rate and improving the heat exchange efficiency.
[0043] In some embodiments, referring to FIG1, the heat exchanger 100 may include a plurality of heat exchange tubes 2 and a plurality of fins 1. The plurality of fins 1 may be arranged side by side in parallel with each other. Adjacent fins 1 are spaced apart by a certain distance. Each heat exchange tube 2 passes through each fin 1, and adjacent heat exchange tubes 2 are connected by a bend to form a fluid channel. A fluid, such as a coolant, can flow through the fluid channel, and the fluid in the fluid channel can exchange heat with the airflow flowing at the fins 1 through the heat exchange tubes 2 and fins 1.
[0044] It should be noted that the heat exchange tube 2 in this embodiment can have any suitable size. The number of heat exchange tubes 2 can be arbitrary. The heat exchange tubes 2 can be made of any suitable material with good heat transfer performance. The number of fins 1 can also be arbitrary. The fins 1 can also have any suitable size. The fins 1 can be made of aluminum or any suitable metal material with good heat transfer performance. The length and width of the fins 1 can be adjusted according to the size of the finned tube heat exchanger 100.
[0045] In some embodiments, as shown in Figures 2 and 3, the fin 1 includes a plurality of fin unit rows 12, which are distributed in the width direction of the fin 1. For example, as shown in Figure 3, the fin 1 may include two fin unit rows 12, which are sequentially connected in the width direction of the fin 1. Of course, this disclosure is not limited to this, and the fin 1 may also include three or more fin unit rows 12. When the fin 1 includes a plurality of fin unit rows 12, the heat exchange tube 2 also forms multiple rows accordingly. The width direction of the fin 1 is the incoming flow direction shown in Figure 4.
[0046] In some embodiments, as shown in Figures 2 and 3, each finned unit row 12 may include multiple finned units 11 distributed along the length direction of the fins 1. Each finned unit 11 is provided with a tube hole 111, and a heat exchange tube 2 passes through the tube hole 111, through which a refrigerant flows. That is, each finned unit 11 can be connected to the heat exchange tube 2 through the tube hole 111, thereby ultimately achieving the heat exchange effect between the fins 1 and the heat exchange tube 2, and thus improving the heat exchange efficiency.
[0047] In some embodiments, as shown in Figures 2 and 3, the tube holes 111 in two adjacent fin unit rows 12 are staggered. That is, each fin unit row 12 can be composed of multiple fin units 11 connected sequentially along the length direction of the fin 1, and the tube holes 111 in one fin unit row 12 and the tube holes 111 in the adjacent fin unit row 12 are staggered. This allows the heat exchange tubes 2 passing through the corresponding tube holes 111 to also be staggered accordingly, which can avoid the heat exchange tubes 2 in different rows from blocking each other in the incoming flow direction, and can further improve the heat exchange efficiency of the heat exchanger 100.
[0048] In some embodiments, referring to FIG5, the fin unit 11 may include a flat region 112, which is arranged circumferentially around the tube hole 111. The flat region 112 surrounds the outer periphery of the tube hole 111 along its circumference. This arrangement increases the contact area between the fins 1 and the tube hole 111, thereby facilitating better heat conduction; it also reduces the flow resistance of the fluid in the flat region 112, i.e., it reduces turbulence between the fins 1, thereby improving fluid flowability; it provides a smoother flow channel, reducing fluid friction loss and thus increasing flow velocity; and it simplifies the manufacturing process, reduces complex processing steps, and improves production efficiency.
[0049] In some embodiments, as shown in Figures 2 and 5, the fin unit 11 further includes a corrugated region 113, which is disposed around the flat region 112 and protrudes toward one side of the fin unit 11 in the thickness direction. The corrugated region 113 can be continuously varied in the thickness direction, that is, the corrugated region 113 forms an undulating shape in the thickness direction.
[0050] In some embodiments, as shown in Figures 2 and 5, the corrugated region 113 may include a first corrugated segment 1131, which includes a first inclined segment 1132 and a second inclined segment 1133 connected sequentially along the incoming flow direction. The first inclined segment 1132 is inclined relative to the second inclined segment 1133. It is understood that the first inclined segment 1132 and the second inclined segment 1133 connected sequentially along the incoming flow direction are constructed in a shape similar to an inverted V-shape. This allows the mutually inclined first inclined segment 1132 and the second inclined segment 1133 to define a windward slope and a leeward slope, thereby increasing their heat exchange contact area with the airflow and increasing the disturbance effect on the airflow, thereby improving the heat exchange efficiency between the airflow and the fins 1.
[0051] In some embodiments, as shown in Figures 6 and 7, the fin unit 11 further includes a transition region 114, which is obliquely connected between the flat region 112 and the corrugated region 113. The transition region 114 intersects with the first inclined section 1132 and the second inclined section 1133, respectively. The transition region 114 can change the extension direction of the flat region 112 and the corrugated region 113, thereby connecting the three into a tight whole. The transition region 114 can also smoothly transition the area from the flat region 112 to the corrugated region 113, thereby reducing the flow resistance of the fluid between different regions, reducing turbulence between different regions, and thus improving the smoothness of fluid flow.
[0052] In some embodiments, as shown in Figure 4, the maximum height of the intersection of the first inclined section 1132 and the second inclined section 1133 (e.g., the crest) is H, and the minimum height of the intersection of the transition zone 114 and the first inclined section 1132 (i.e., the windward slope) is H1. Since a smaller minimum height at the intersection of the transition zone 114 and the first inclined section 1132 results in a larger corrugated area loss, when 1 / 3 × H > H1, the portion of the first inclined section 1132 adjacent to the transition zone 114 is smaller, resulting in a larger loss area for the first inclined section 1132. Consequently, the finned unit 11 itself has a poor heat dissipation effect on the heat exchange tube 2 using the corrugated area 113, affecting the heat exchange effect of the heat exchanger 100. Furthermore, the greater the minimum height at the intersection of the transition zone 114 and the first inclined section 1132, the greater the fluid resistance of the incoming flow. When H1 > 2 / 3 × H, the portion of the first inclined section 1132 adjacent to the transition zone 114 is larger, resulting in a smaller loss area for the first inclined section 1132. However, because the portion of the first inclined section 1132 adjacent to the transition zone 114 is relatively high, it will hinder the fluid flow between two adjacent fins 1, significantly affecting the smoothness of fluid flow and consequently impacting the heat exchanger 100's heat exchange efficiency. Therefore, H and H1 can satisfy the following relationship: 1 / 3 × H ≤ H1, and H1 ≤ 2 / 3 × H. When 1 / 3×H≤H1 and H1≤2 / 3×H, the corrugated loss area of the first corrugated section 1131 can be reduced, thereby increasing the heat transfer area of the first corrugated section 1131 for the incoming flow. It can also reduce the flow resistance of the first inclined section 1132 for the incoming flow, that is, reduce the pressure drop of the incoming flow when passing through the first corrugated section 1131, thereby improving the smoothness of fluid flow at the first corrugated section 1131, and thus improving the overall heat transfer efficiency of the heat exchanger 100. For example, H1 can be 0.4H, 0.5H, 0.6H, etc., but is not limited to these, as long as the aforementioned relationship is satisfied.
[0053] In this embodiment, by setting up a heat exchanger 100, the corrugation height in front of the heat exchange tube 2 can be reasonably controlled. On the one hand, this reduces the loss of heat exchange area on the first corrugated section 1131, and on the other hand, it can reduce the flow resistance of the incoming flow, thereby improving the overall heat exchange efficiency.
[0054] In some embodiments, as shown in Figures 2 and 5, the corrugated region 113 may include a second corrugated segment 1134. Along the flow direction, the second corrugated segment 1134 is located downstream of the first corrugated segment 1131. The second corrugated segment 1134 can further increase the undulating profile of the corrugated region 113, thereby increasing the heat transfer contact area of the corrugated region 113 and thus improving the heat transfer efficiency of the fin unit 11. In addition, the above arrangement can also allow the airflow to pass through multiple corrugated segments formed on the corrugated fin sequentially, thereby creating periodic disturbances to the heat transfer airflow and further improving the heat transfer efficiency of the fin 1.
[0055] In some embodiments, as shown in Figures 5 and 7, the second corrugated section 1134 includes a third inclined section 1135 and a fourth inclined section 1136 connected sequentially along the incoming flow direction. The third inclined section 1135 is inclined relative to the fourth inclined section 1136, and the transition zone 114 intersects with both the third inclined section 1135 and the fourth inclined section 1136. It is understood that, along the incoming flow direction, the sequentially connected third inclined section 1135 and fourth inclined section 1136 are constructed in a shape resembling an inverted V-shape, thus defining a windward slope and a leeward slope, thereby increasing their heat exchange contact area with the airflow and enhancing their disturbance effect on the airflow, thereby improving the heat exchange efficiency between the airflow and the fins 1.
[0056] In some embodiments, referring to Figure 4, the maximum height of the intersection of the third inclined section 1135 and the fourth inclined section 1136 (e.g., the crest) is H, and the minimum height of the intersection of the transition zone 114 and the third inclined section 1135 (i.e., the windward slope) is H2. Since a smaller minimum height at the intersection of the transition zone 114 and the third inclined section 1135 results in a larger corrugated area loss, when 1 / 3 × H > H2, the portion of the third inclined section 1135 adjacent to the transition zone 114 is smaller, leading to a larger loss area in the third inclined section 1135. Consequently, the finned unit 11 itself has a poor heat dissipation effect on the heat exchange tube 2 using the corrugated area 113, affecting the heat exchange effect of the heat exchanger 100. Furthermore, the greater the minimum height at the intersection of the transition zone 114 and the third inclined section 1135, the greater the fluid resistance of the incoming flow. When H2 > 2 / 3 × H, the portion of the third inclined section 1135 adjacent to the transition zone 114 is larger, and the loss area of the third inclined section 1135 is smaller. However, since the portion of the third inclined section 1135 adjacent to the transition zone 114 is relatively high, it will hinder the fluid flow between two adjacent fins 1, which will have a significant impact on the smoothness of fluid flow and will also affect the heat exchange effect of the heat exchanger 100.
[0057] Therefore, H and H2 can also satisfy the relationship: H2 ≥ 1 / 3 × H, and H2 ≤ 2 / 3 × H. When H2 ≥ 1 / 3 × H and H2 ≤ 2 / 3 × H, the corrugation loss area of the second corrugated section 1134 can be reduced, thereby increasing the heat transfer area of the second corrugated section 1134 for the incoming flow; it can also reduce the flow resistance of the third inclined section 1135 for the incoming flow, thereby improving the smoothness of fluid flow at the second corrugated section 1134, and thus improving the overall heat transfer efficiency of the heat exchanger 100. For example, H2 can be 0.4H, 0.5H, 0.6H, etc., but is not limited to these, as long as the aforementioned relationship is satisfied.
[0058] In some embodiments, H1 and H2 satisfy the relationship: H1 = H2. It is understood that the minimum height at the intersection of the transition zone 114 and the first inclined section 1132 is equal to the minimum height at the intersection of the transition zone 114 and the third inclined section 1135, which can improve the manufacturing consistency of the first corrugated section 1131 and the second corrugated section 1134.
[0059] In some embodiments, along the flow direction, the plane perpendicular to the flow direction and passing through the central axis of the pipe hole 111 is the interface, and the first corrugated section 1131 and the second corrugated section 1134 are symmetrical about the interface. That is, the first corrugated section 1131 and the second corrugated section 1134 are symmetrically arranged about the interface, so that the first inclined section 1132 and the second inclined section 1133 on the first corrugated section 1131 are symmetrically arranged about the interface with the third inclined section 1135 and the fourth inclined section 1136 on the second corrugated section 1134, respectively. This arrangement facilitates manufacturing and helps to balance the heat distribution of the airflow, reducing or avoiding structural warping and angular deviation problems caused by thermal asymmetry, thereby improving manufacturability and heat exchange efficiency.
[0060] In some embodiments, as shown in FIG4, the plane containing the flat region 112 is the first reference plane, the width of the orthographic projection of the first inclined section 1132 on the first reference plane is d1, and the width of the orthographic projection of the second inclined section 1133 on the first reference plane is d2. d1 and d2 satisfy the relationship: d1≤d2. The orthographic projection mentioned here refers to the projection in the direction perpendicular to the first reference plane. That is, the orthographic projection width of the first inclined section 1132 towards the first reference plane is not greater than the projection width of the second inclined section 1133. When the orthographic projection width of the first inclined section 1132 is less than the orthographic projection width of the second inclined section 1133, it helps the intersection of the first inclined section 1132 and the second inclined section 1133 to shift away from the center of the tube hole 111. This can reduce the loss of corrugated area on the first corrugated section 1131, thereby effectively preserving the corrugated shape on the first corrugated section 1131 and improving the heat exchange efficiency of the fin 1. Furthermore, when the orthographic projection width of the first inclined section 1132 is equal to the orthographic projection width of the second inclined section 1133, that is, the two are symmetrical to each other, manufacturing consistency can be improved, manufacturing process can be simplified, and thus production efficiency can be improved.
[0061] In some embodiments, as shown in Figure 4, the width of the orthographic projection of the third inclined section 1135 onto the first reference plane is d3, and the width of the orthographic projection of the fourth inclined section 1136 onto the first reference plane is d4. d3 and d4 satisfy the relationship: d3 ≥ d4. The orthographic projection mentioned here refers to the projection in the direction perpendicular to the first reference plane. That is, the orthographic projection width of the fourth inclined section 1136 onto the first reference plane is not greater than the orthographic projection width of the third inclined section 1135. When the orthographic projection width of the fourth inclined section 1136 is less than the orthographic projection width of the third inclined section 1135, it helps the intersection of the third inclined section 1135 and the fourth inclined section 1136 to shift away from the center of the tube hole 111. This can reduce the loss of corrugated area on the second corrugated section 1134, thereby effectively preserving the corrugated shape on the second corrugated section 1134 and improving the heat exchange efficiency of the fin 1. Furthermore, when the orthographic projection width of the third inclined section 1135 is equal to the orthographic projection width of the fourth inclined section 1136, that is, when the two are symmetrical, manufacturing consistency can be improved, manufacturing process can be simplified, and thus production efficiency can be improved.
[0062] In some embodiments, as shown in FIG4, the plane parallel to the incoming flow direction and passing through the central axis of the pipe hole 111 is the second reference plane. The transition zone 114 forms an angle A on the second reference plane, and the transition zone 114 forms an angle B with the first reference plane. A and B satisfy the relationship: B = (180° - A) / 2. It is understandable that the transition zone 114 extends outward at an angle away from the tube hole 111 along the radial direction of the tube hole 111. The included angle A formed by the transition zone 114 on the second reference plane and the included angle B formed by the transition zone 114 and the first reference plane are parametrically related. This allows the inclination angle of the transition zone 114 at the first corrugated section 1131 and the second corrugated section 1134 to be the same, thereby ensuring manufacturing consistency and improving production efficiency. Furthermore, by reasonably controlling the included angle A (under the premise that the orthographic projection width of the first corrugated section 1131 and the second corrugated section 1134 remains unchanged), the minimum height H1 at the intersection of the transition zone 114 and the first inclined section 1132 and the minimum height H2 at the intersection of the transition zone 114 and the second inclined section 1133 can be controlled. This achieves the effect of reducing the heat exchange area loss on the corrugated plate and reducing the flow resistance of the incoming flow, thereby improving the overall heat exchange efficiency of the heat exchanger 100.
[0063] In some embodiments, as shown in Figure 4, B satisfies the relationship: B ≥ 30° and B ≤ 45°. For example, B can be 30°, 35°, 40°, and 45°, etc., and is not limited thereto. In this embodiment, by controlling the angle B formed by the transition zone 114 and the first reference plane within the range of 30° and 45°, it is beneficial to smoothly guide and collect water vapor near the fin 1 onto the transition zone 114, thereby improving the drainage effect.
[0064] In some embodiments, as shown in Figures 4 and 5, the flat region 112 can be constructed in an annular shape, the outer diameter of the flat region 112 is D, and the radial distance from the intersection of the first inclined section 1132 and the second inclined section 1133 to the central axis of the pipe hole 111 can be d5. d1, d5, D, H1 and tanB satisfy the relationship: d5≤D / 2+H1×tanB≤d1+d5.
[0065] In this embodiment, by establishing a relationship between the magnitude parameters d1, d5, D, H1 and the included angle B, the position of the intersection of the transition zone 114 and the first inclined section 1132 can be limited to the position between the intersection of the first corrugated section 1131 and the edge side of the first corrugated section 1131. The intersection of the first corrugated section 1131 is the intersection of the first inclined section 1132 and the second inclined section 1133. The edge side of the first corrugated section 1131 is the side of the first corrugated section 1131 away from the center of the tube hole 111. This arrangement can maximize the preservation of the corrugated shape of the first corrugated section 1131, that is, reduce the loss of corrugated area. Secondly, the corrugated height before the heat exchange tube 2 (that is, the minimum height at the intersection of the transition zone 114 and the first inclined section 1132) can be reasonably controlled to reduce the flow resistance when the incoming flow passes through the first inclined section 1132, thereby improving the overall heat exchange efficiency of the fin 1.
[0066] In some embodiments, referring to FIG4, the finned unit 11 may further include a drainage section 115, which may be disposed between the first corrugated section 1131 and the second corrugated section 1134, and the drainage section 115 is coplanar with the flat area 112. In other words, the drainage section 115 may be straight and extend perpendicular to the incoming flow direction. The drainage section 115 is connected between the second inclined section 1133 of the first corrugated section 1131 and the third inclined section 1135 of the second corrugated section 1134. In this way, water droplets formed on the outer wall of the heat exchange tube 2 can be collected in the drainage section 115 (that is, the low-lying area of the finned unit 11) and then flow out along the drainage section 115, thereby reducing or preventing condensate from clogging in the flat area 112, and thus improving the drainage effect of the fins 1.
[0067] In some embodiments, referring to Figures 4 and 7, the heat exchanger 100 may further include a straight section 116 connected to both ends of the finned unit 11 in the width direction. The straight section 116, connecting both ends of the finned unit 11 in the width direction, allows the straight section 116 to pre-guide the airflow, thereby enabling the airflow to flow more smoothly to the corrugated area 113, thus improving the smoothness of the heat exchange airflow. Furthermore, the straight section 116 can also enhance the structural strength of the finned unit 11 to some extent.
[0068] In some embodiments, if the height of the corrugated section protruding too high in the thickness direction of the fin unit 11, it will increase the overall volume of the fin unit 11, while if the height of the corrugated section protruding too low, it will reduce the heat exchange effect. Therefore, the height H of the corrugated section (first corrugated section 1131 and second corrugated section 1134) is designed to be greater than or equal to 0.3 mm and less than or equal to 0.7 mm. This ensures the heat exchange effect while reducing the overall volume and production cost, thus balancing practicality and economy. For example, H can be 0.3 mm, 0.4 mm, 0.5 mm, and 7 mm, and is not limited to these.
[0069] In some embodiments, referring to FIG4, the flat region 112 can be configured as an annular shape, and the outer diameter of the flat region 112 is D, where D satisfies the relationship: D≥9mm. For example, D can be 9mm, 10mm, 12mm, and 15mm, etc., and is not limited thereto. The annular flat region 112 better conforms to the contour of the circular tube, and can uniformly transfer heat from the circular tube to the transition region 114 and the corrugated region 113 along its own radial direction, thereby effectively improving heat transfer uniformity. Moreover, the outer diameter of the flat region 112 is greater than 9mm, which avoids the problem of a short mold life caused by the flat region 112 being too small, thereby reducing manufacturing costs and improving economic efficiency.
[0070] In some embodiments of this disclosure, an air conditioner is also provided. The air conditioner may include the heat exchanger 100 of any of the above embodiments. Thus, the air conditioner with the heat exchanger 100 can reduce the loss of heat exchange area on the corrugated area 113 by reasonably controlling the corrugation height in front of the heat exchange tube 2, and can also reduce the flow resistance of the incoming flow, thereby improving the overall heat exchange efficiency.
[0071] Moreover, compared to corrugated fins in related heat exchanger technologies, the fins 1 (i.e., the corrugated fins of this patent) in some embodiments of this disclosure can increase the heat transfer area and enhance the turbulence of the incoming flow while achieving the same heat transfer capacity, thereby improving the external heat transfer coefficient and the amount of heat transfer. Therefore, by using the fin structure provided in some embodiments of this disclosure, the number of fins 1 can be reduced to achieve the same heat transfer capacity, thus reducing the cost of the heat exchanger 100. For example, when d5 = 4.32 mm, H = 0.9 mm, and H1 = 0.56 mm, compared to corrugated fins in related technologies, the heat transfer area of the corrugated fins of this patent can be increased by 1.73%. Through numerical simulation, it is further obtained that the external heat transfer coefficient is increased by 5.16%, the amount of heat transfer is increased by 3.82%, and the comprehensive heat transfer factor j / f is [missing data]. (1 / 3) The heat exchange performance is improved by 1.38%, indicating that the corrugated fin of this patent has better heat exchange performance and a lower surface temperature. In addition, referring to Figure 8, the fin 1 (i.e., the corrugated fin of this patent) designed according to some embodiments of this disclosure shows better heat exchange performance at different wave heights compared with corrugated fins of related technologies.
[0072] In some embodiments, the air conditioner may be an integrated air conditioner. For example, the air conditioner in the embodiments of this disclosure may be a window air conditioner, which may include a heat exchanger 100.
[0073] In some embodiments, the window air conditioner includes a casing and a compressor, an evaporator, and a condenser located within the casing. At least one of the evaporator and the condenser is a heat exchanger 100.
[0074] In some embodiments, the integrated air conditioner is not limited to a window air conditioner, but may also be a portable air conditioner, which may include a heat exchanger 100.
[0075] In some embodiments, the air conditioner may also be a split-type air conditioner, which may include an indoor unit and an outdoor unit, at least one of which may include a heat exchanger 100.
[0076] In some embodiments, the air conditioner may be installed on a windowsill as a window air conditioner. Referring to Figures 9 and 10, an embodiment of this disclosure provides an air conditioner 500, which may include an air conditioner body 510 and an air duct component 400.
[0077] In some embodiments, the air conditioning unit 510 may include a chassis and a compressor, evaporator, and condenser located within the chassis. At least one of the evaporator and condenser may be a heat exchanger 100.
[0078] In some embodiments, the air duct 400 is configured to be detachably connected to the air conditioning body 510, and when the air conditioning body 510 is installed on the windowsill 300, the air duct 400 is located on the indoor side 310 of the windowsill 300.
[0079] In this implementation, during summer, the duct component 400 connects the air conditioner unit 510 and the indoor side 310 of the window sill 300, enabling the normal operation of the air conditioner 500. During winter, by removing the detachable duct component 400, the window on the window sill 300 can be completely closed without disassembling the entire air conditioner unit 510. This does not alter the overall structure of the air conditioner unit 210, thus not affecting its normal operation. In summer, there is no need to reinstall the air conditioner unit 510 on the window sill 300; simply reinstalling the duct component 400 onto the air conditioner unit 510 achieves indoor insulation and sealing, improves the ease of use of the air conditioner 500, and further enhances the user experience.
[0080] As can be seen, by setting a detachable air duct component 400 to connect with the air conditioner body 510, this disclosure can solve the problems of window space occupation, insufficient sealing and cumbersome disassembly and assembly caused by the installation method of the air conditioner 500 while maintaining the price advantage and installation convenience of the air conditioner 500.
[0081] In some embodiments, when the duct component 400 is detachably installed on the air conditioner body 510, it is mainly detachably connected to the front end of the air conditioner body 510, which refers to the end of the air conditioner body 510 facing the indoor side 310 of the windowsill 300. In order to minimize changes to the structure of the air conditioner body 510, referring to FIG13, a frame portion 514 can be provided on the front surface 515 of the air conditioner body 510, so that when the duct component 400 is connected to the air conditioner body 510, at least part of it can extend into the frame portion 514 and be detachably connected to the frame portion 514.
[0082] In this embodiment, a protruding frame portion 514 is provided on the front surface 515 of the air conditioner body 510, thereby allowing a structure that can be detachably connected to the air duct component 400 to be provided on the frame portion 514, without the need to directly install it on the air conditioner body 510. This arrangement minimizes the impact on the original structure of the air conditioner body 510; simply adding a frame portion 514 enables a detachable connection with the air duct component 400, thus avoiding damage to the air conditioner body 510 or changes in its installation position caused by frequent disassembly and installation of the air duct component 400, which could affect subsequent normal use.
[0083] In some embodiments, the frame portion 514 may include a hollow sheet metal frame extending from the housing of the air conditioner body 510. The frame portion 514 does not affect the arrangement of the first air inlet 512 and the first air outlet 511 on the air conditioner body 510 in FIG. 13. The front end surface 515 of the air conditioner body 510 refers to the side surface of the air conditioner body 510 located near the indoor side 310 of the windowsill 300. This front end surface 515 can be detachably connected to the air duct component 400 for air intake, air outlet, and venting.
[0084] To facilitate understanding of the specific structure of the air duct component 400, the specific structure of the air duct component 400 will be described in detail below with reference to the accompanying drawings.
[0085] In some embodiments, referring to FIG13, the air conditioner body 510 may have a first air inlet 512 and a first air outlet 511. The air duct component 400 is configured to be detachably connected to the air conditioner body 510, and when the air conditioner body 510 is installed on the windowsill 300, the air duct component 400 is located on the indoor side 310 of the windowsill 300. By installing the entire air conditioner body 510 on the windowsill 300, the air duct component 400 is located on the indoor side 310 of the windowsill 300, and the air duct component 400 is detachably connected to the air conditioner body 510.
[0086] In some embodiments, a portion of the air conditioner body 510 may be located within the space defined by the window frame 330 of the windowsill 300, and another portion of the air conditioner body 510 may extend to the outdoor side 320 of the windowsill 300, so that in winter, the window on the windowsill 300 can be completely closed by removing the detachable air duct component 400 without disassembling the entire air conditioner body 510. However, this is not a limitation; the air conditioner body 510 may also be located entirely within the space defined by the window frame 330 of the windowsill 300.
[0087] In some embodiments, as shown in Figures 12 and 13, the air duct 400 may include an air outlet duct 411, which is correspondingly arranged with a first air outlet 511. The air outlet duct 411 is configured to connect the indoor side 310 of the windowsill 300 with the first air outlet 511, so that the airflow blown out of the first air outlet 511 of the air conditioner body 510 can be blown to the indoor side 310 through the air outlet duct 411, thereby realizing the regulation of indoor temperature.
[0088] In some embodiments, as shown in Figures 12 and 13, the air duct 400 includes an air inlet duct 412, which is correspondingly disposed with a first air inlet 512. The air inlet duct 412 is configured to connect the indoor side 310 of the windowsill 300 with the first air inlet 512, so that the first air inlet 512 can draw in air from the indoor side 310, thereby realizing the circulation of indoor and outdoor air and regulating the indoor temperature.
[0089] In some embodiments, the air duct component 400 can be detachably connected to the air conditioner body 510 via at least one of a button structure, a snap-fit structure, a magnetic structure, or a threaded structure. That is to say, any one or any combination of the aforementioned detachable connection methods can enable the air duct component 400 to be installed or detached from the air conditioner body 510. Thus, in winter, it is not necessary to disassemble the entire air conditioner body 510; only the air duct component 400 needs to be removed, allowing the window on the windowsill 300 to be completely closed, achieving the effect of indoor sealing and heat preservation.
[0090] The following will describe in detail how the air duct component 400 is detachably connected to the air conditioning body 510 via a snap-fit structure.
[0091] In some embodiments, referring to Figures 13 and 15, the duct component 400 is provided with a first latching portion 413, and the air conditioner body 510 is provided with a second latching portion 513. The first latching portion 413 is configured to engage with the second latching portion 513, so that the duct component 400 is detachably connected to the air conditioner body 510. This latching connection facilitates quick installation or removal of the duct component 400 by the user, thereby meeting the user's needs for improved indoor insulation and sealing in winter. Simultaneously, it reduces the damage to the air conditioner body or changes in installation position caused by frequent disassembly and reassembly of the air conditioner body 510, effectively improving the user's experience with the air conditioner 500 and extending its service life. It is understood that in other embodiments, the first latching portion 413 may also be provided on the air conditioner body 510, and the second latching portion 513 may be provided on the duct component 400; this disclosure does not limit this aspect.
[0092] In some embodiments, referring to FIG13, the aforementioned air conditioner body 510 has a protruding frame portion 514 on its front end surface 515. The air duct component 400 extends at least partially into the frame portion 514 and is detachably connected to the frame portion 514. Specifically, the first latching portion 413 on the air duct component 400 extends at least partially into the frame portion 514. Thus, the connection between the air duct component 400 and the air conditioner body 510 can be detachably achieved through the frame portion 514. This arrangement minimizes impact on the original structure of the air conditioner body 510; simply adding a frame portion 514 achieves a detachable connection with the air duct component 400. This avoids damage to the body or changes in the installation position caused by frequent disassembly and installation of the air duct component 400, which could affect subsequent normal use.
[0093] Of course, as another embodiment, the second latching part 513 may also be directly disposed on the air conditioner body 510, and this disclosure does not specifically limit it in this way.
[0094] In some embodiments, when the duct component 400 includes a first latching part 413, a second latching part 513 is provided on the frame part 514. The first latching part 413 and the second latching part 513 are engaged to achieve the engagement connection between the duct component 400 and the air conditioner body 510, so that the duct component 400 can be detachably connected to the air conditioner body 510. Thus, when the air conditioner body 510 is set on the outdoor side 320 of the windowsill 300, it can also be connected to the indoor side 310 of the windowsill 300 through the duct component 400, thereby realizing the normal use of the air conditioner 500. When it is necessary to close the window to achieve heat preservation and sealing of the room, the user can remove the engagement connection between the first latching part 413 and the second latching part 513 to remove the duct component 400, so that the window can be completely closed, effectively ensuring the sealing and heat preservation of the window. At the same time, since it is not necessary to remove the entire air conditioner 500, the convenience and stability of the air conditioner 500 can also be effectively improved.
[0095] In some embodiments, one of the first latching portion 413 and the second latching portion 513 may be a protrusion, and the other may be a latching hole.
[0096] In some embodiments, the second latching part 513 may be a latching hole 5141, so that the latching hole 5141 can be directly opened on the frame part 514, while the first latching part 413 may be a protrusion. By providing a protrusion on the air duct part 400, the protrusion can be aligned with the latching hole 5141 and the protrusion can be fastened in the latching hole 5141 during installation.
[0097] In some embodiments, referring to FIG11, the air duct component 400 includes a first side 41a and a second side 41b disposed opposite to each other. The first side 41a is configured to be disposed close to the air conditioner body 510, and a first latching part 413 is disposed on the wall surface of the air outlet duct 411 and / or the air inlet duct 412 located on the first side 41a. By providing the first latching part 413 on the side of the air duct component 400 close to the air conditioner body 510, the first latching part 413 can be directly engaged with the second latching part 513 on the air conditioner body 510, so that the user can install or disassemble the first latching part 413 and the second latching part 513 by means of the engagement and disassembly, making the installation or disassembly of the air duct component 400 simpler and reducing the waste of time.
[0098] In some embodiments, referring to Figures 15 and 22, when the first latching portion 413 is disposed on the wall surface of the air outlet duct 411 and / or the air inlet duct 412 located on the first side 41a, the first latching portion 413 includes multiple portions. The air outlet duct 411 has an upper wall surface 411a along the first direction F1, and the air inlet duct 412 has a side wall surface 412a along the second direction F2. A portion of the first latching portion 413 is disposed on the upper wall surface 411a, and another portion of the first latching portion 413 is disposed on the side wall surface 412a. The first direction F1 is the height direction of the duct component 400, and the second direction F2 intersects the first direction F1.
[0099] In this embodiment, by setting a portion of the first latching part 413 on the upper wall surface 411a of the air outlet duct 411 along the first direction F1, this portion of the first latching part 413 can restrict the movement of the duct component 400 in the second direction F2; by setting another portion of the first latching part 413 on the side wall surface 412a of the air inlet duct 412 along the second direction F2, this portion of the first latching part 413 can restrict the movement of the duct component 400 in the first direction F1; thus, the two portions of the first latching part 413 can jointly restrict the movement of the duct component 400 in the first direction F1 and the second direction F2, thereby effectively improving the installation stability of the duct component 400 on the air conditioner body 510, thereby achieving stable transmission of airflow to the air conditioner body 510 and achieving efficient control of indoor temperature.
[0100] It is understandable that the first direction F1 is the height direction of the air duct component 400, and the second direction F2 intersects with the first direction F1. At this time, the second direction F2 can be either the depth direction or the width direction of the air duct component 400. Since the first latching part 413 is located on the wall surface of the first side 41a of the air outlet duct 411 and / or the air inlet duct 412, that is, the direction from the first side 41a to the second side 41b is the depth direction of the air duct component 400, it can be known that the second direction F2 is the width direction of the air duct component 400.
[0101] In some embodiments, referring to Figures 13 and 18, the first latching portion 413 may include a latching portion 4131, which protrudes from the inner wall surface 414 of the air duct component 400. The latching portion 4131 is configured to correspond to a latching hole 5141 on the air conditioner body 510, thereby achieving a latching connection between the air conditioner body 510 and the air duct component 400. The latching portion 4131 may include, but is not limited to, protrusions, ribs, hooks, etc., and this embodiment does not limit its application.
[0102] In some embodiments, as shown in FIG18, the first latching portion 413 includes an extension portion 4132 extending from the inner wall surface 414 of the air duct member 400 to the outer wall surface 415 of the air duct member 400. The extension portion 4132 at least partially protrudes from the outer wall surface 415 of the air duct member 400, so that a latching position 41321 is formed between the extension portion 4132 and the inner wall surface 414 of the air duct member 400, which is recessed relative to the inner wall surface 414 of the air duct member 400.
[0103] In this embodiment, a latching position 41321 is directly formed between the first latching part 413 and the inner wall surface 414 of the air duct component 400. Thus, when it is necessary to remove the air duct component 400 from the air conditioner body 510, the user can insert their fingers or other tools (such as a screwdriver or other objects with a certain degree of hardness) into the latching position 41321 to adjust the connection position between the latching part 4131 and the latching hole 5141, causing the latching part 4131 to disengage from the latching hole 5141. This releases the latching connection between the first latching part 413 of the air duct component 400 and the second latching part 513 of the air conditioner body 510, thereby removing the air duct component 400 from the air conditioner body 510. This disassembly method is simple and convenient, requiring no additional structure to release the connection between the first latching part 413 and the second latching part 513, effectively simplifying the connection and separation structure design of the air duct component 400 and the air conditioner body 510.
[0104] In some embodiments, as shown in Figures 15 and 18, the handle 41321 is disposed on the side wall surface 412a of the air inlet duct 412 along the second direction F2. For example, the handle 41321 can be disposed on two side wall surfaces 412a of the air inlet duct 412 along the second direction F2, allowing the user to hold the handle 41321 located on both sides of the duct component 400 with both hands, thereby enabling the user to install and remove the duct component 400. This facilitates user operation and also provides for the proper alignment and installation of the duct component 400.
[0105] In some embodiments, the gripper 41321 is disposed on the side wall surface 412a at a lower position along the height direction of the air duct component 400. The lower position of the gripper 41321 conforms to the user's gripping logic, making it easier for the user to grip the air duct component 400 and achieve proper installation.
[0106] The specific structures of the air outlet duct 411 and the air inlet duct 412 will be described in detail below.
[0107] In some embodiments, as shown in Figures 11 and 23, the air outlet duct 411 has a constricted end on the second side 41b and a flared end on the first side 41a. Since the first side 41a of the duct component 400 is configured close to the air conditioner body 510, the second side 41b of the duct component 400 can be the side located close to the indoor side 310 of the windowsill 300. On the one hand, since the air outlet duct 411 is correspondingly set to the first air outlet 511 of the air conditioner body 510, that is, the end of the air outlet duct 411 on the first side 41a is connected to the first air outlet 511, the air outlet duct 411 is widened at the end on the first side 41a, which can introduce as much airflow as possible from the first air outlet 511 into the air outlet duct 411, thereby increasing the amount of air blown into the room; on the other hand, the air outlet duct 411 is narrowed at the end on the second side 41b, which can concentrate the airflow in the air outlet duct 411, so that the air blown out by the air outlet duct 411 can reach a farther area, thereby regulating the temperature in various parts of the room.
[0108] In some embodiments, as shown in Figures 11 and 23, the air inlet duct 412 is narrowed at one end on the second side 41b and widened at the other end on the first side 41a. On the one hand, since the air inlet duct 412 is correspondingly set to the first air inlet 512 of the air conditioner body 510, that is, the end of the air inlet duct 412 on the first side 41a is connected to the first air inlet 512, the end of the air inlet duct 412 on the first side 41a is widened, so that the air intake of the air inlet duct 412 can enter the first air inlet 512 as much as possible, thereby increasing the air intake of the first air inlet 512 and improving the heat exchange efficiency of the air conditioner body 510. On the other hand, the end of the air inlet duct 412 on the second side 41b is narrowed, and the other end of the air inlet duct 412 on the first side 41a is widened, which can effectively meet the air intake of the first air inlet 512 while reducing the resistance to air flow and improving the efficiency of air circulation, thereby optimizing the performance of air circulation.
[0109] It is understandable that the above-mentioned narrowing refers to the reduction in the opening width of the air outlet duct 411 and the air inlet duct 412, while the above-mentioned widening refers to the increase in the opening width of the air outlet duct 411 and the air inlet duct 412.
[0110] In some embodiments, as shown in Figures 20 and 21, the air outlet duct 411 includes a first duct section 4111 and a second duct section 4112, which are sequentially connected to the first duct section 4111 along the direction from the first side 41a to the second side 41b to form the air outlet duct 411.
[0111] In some embodiments, as shown in Figures 18 and 21, the inclination angle α of at least one inner wall surface 414 of the first air duct section 4111 towards the third direction F3 is greater than the inclination angle β of at least one inner wall surface 414 of the second air duct section 4112 towards the third direction F3, so that the air outlet duct 411 is closed at the second side 41b. The third direction F3 refers to the direction from the first side 41a to the second side 41b.
[0112] In this embodiment, the second air duct section 4112 is configured close to the air conditioner body 510, and the first air duct section 4111 is configured close to the indoor side 310 of the windowsill 300. The second air duct section 4112 and the first air duct section 4111 are connected in sequence, and the inclination angle of at least one inner wall surface 414 of the first air duct section 4111 towards the third direction F3 is greater than the inclination angle of at least one inner wall surface 414 of the second air duct section 4112 towards the third direction F3. This allows the airflow of the air outlet duct 411 to pass from the first air outlet 511 through the second air duct section 4112 and the first air duct section 4111 in sequence, and finally blow into the indoor side 310. The airflow can blow out from bottom to top. By utilizing the physical property of cold air naturally sinking, an airflow circulation from top to bottom can be formed in the room, so that the indoor temperature can be more evenly distributed more quickly, thereby achieving rapid cooling of the room.
[0113] In some embodiments, at least one inner wall surface 414 of the first air duct section 4111 may be the bottom wall surface of the first air duct section 4111 along the first direction F1, or the top wall surface of the first air duct section 4111 along the first direction F1. Of course, as other examples, it may also be the top and bottom wall surfaces of the first air duct section 4111 along the first direction F1. This disclosure does not limit this aspect.
[0114] In some embodiments, the tilt angle α of the first air duct section 4111 toward the third party F3 can be 35°-55°. For example, the tilt angle α of the first air duct section 4111 toward the third party F3 can include, but is not limited to, 35°-40°, 40°-45°, 45°-50°, 50°-55°, etc. For example, the tilt angle α of the first air duct section 4111 toward the third party F3 can include, but is not limited to, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49°, 50°, 51°, 52°, 53°, 54°, 55°, etc. The embodiments disclosed herein do not specifically limit this.
[0115] This configuration allows the airflow of the air duct 411 to blow upwards, reducing or preventing indoor air from accumulating in the lower part of the room, and preventing the air outlet 113 of the air duct 411 from being too high, making it difficult for the airflow to blow further into the room and instead blowing only upwards. In other words, by utilizing the physical property of cold air naturally sinking, an airflow circulation from top to bottom can be formed in the room, thereby enabling the indoor temperature to be distributed more evenly more quickly, thus achieving rapid cooling of the room.
[0116] In some embodiments, the tilt angle β of the second air duct section 4112 toward the third direction F3 can be 2°-10°. For example, the tilt angle β of the second air duct section 4112 toward the third direction F3 includes, but is not limited to, 2°-4°, 4°-6°, 6°-8°, 8°-10°, etc. Exemplarily, the tilt angle β of the second air duct section 4112 toward the third direction F3 includes, but is not limited to, 2°, 2.5°, 3°, 3.5°, 4°, 4.5°, 5°, 5.5°, 6°, 6.5°, 7°, 7.5°, 8°, 8.5°, 9°, 9.5°, 10°, etc.
[0117] This configuration allows the second air duct section 4112 to guide the airflow from the first air outlet 511 at a small angle, and works in conjunction with the first air duct section 4111 to form a streamlined air outlet duct 411, thereby effectively reducing air resistance and improving airflow circulation efficiency.
[0118] In some embodiments, as shown in Figures 15 and 20, the air inlet duct 412 includes a third duct section 4121, which includes a first wall surface 41211 and a second wall surface 41212 along the height direction of the duct component 400, to connect to the first air inlet 512 of the air conditioning body 510. The height direction of the duct component 400 is the aforementioned first direction F1.
[0119] In some embodiments, as shown in FIG20, the air inlet duct 412 further includes a fourth duct section 4122, which is sequentially connected to the third duct section 4121 along the direction from the first side 41a to the second side 41b. The fourth duct section 4122 includes a third wall surface 41221 and a fourth wall surface 41222 along the height direction of the duct member 400. The third wall surface 41221 is connected to the first wall surface 41211, and the fourth wall surface 41222 is connected to the second wall surface 41212. At least one of the fourth wall surface 41222 and the second wall surface 41212 is configured as an arc-shaped surface, and the connection between the fourth wall surface 41222 and the second wall surface 41212 is an arc-shaped transition. Since the connection between the fourth wall surface 41222 and the second wall surface 41212 is an arc transition, and at least one of the fourth wall surface 41222 and the second wall surface 41212 is an arc surface, the air inlet duct 412 can form a streamlined air duct. The airflow entering the air inlet duct 412 can effectively improve the airflow efficiency and reduce the airflow resistance, thereby optimizing the airflow in the air inlet duct 412.
[0120] In some embodiments, referring to FIG20, along the height direction of the air duct component 400, the fourth wall surface 41222 is located below the second wall surface 41212, so that the air inlet duct 412 is flared on the first side 41a. Since the fourth wall surface 41222 is located below the third wall surface 41221, that is, along the height direction of the air duct component 400, the entire third air duct section 4121 is located above the fourth air duct section 4122, and the airflow direction of the air inlet duct 412 is sequentially the third air duct section 4121, the fourth air duct section 4122, and finally enters the first air inlet 512, therefore, based on Bernoulli's principle, after the airflow enters the third air duct section 4121, it forms a certain drop with the fourth air duct section 4122, thereby increasing the power of airflow and optimizing the airflow efficiency, thus improving the return air effect of the first air inlet 512, and thereby achieving efficient operation of the air conditioning body 510.
[0121] In some embodiments, as shown in Figures 14 and 20, the air inlet 4125 of the third air duct section 4121 is provided with a return air component 4123. The return air component 4123 can effectively prevent external debris and water droplets from entering the air inlet duct 412, thereby effectively protecting the air conditioner body 510 from damage and ensuring the stable operation of the air conditioner 500. In addition, it can also enhance the aesthetics of the air duct component 400.
[0122] It is understood that the return air component 4123 may include, but is not limited to, return air mask, return air mesh, etc., and this embodiment does not limit it.
[0123] In some embodiments, referring to FIG20, the return air component 4123 is also provided with a filter 4124. Since the third air duct section 4121 belongs to the air inlet duct 412, it is necessary to draw outside air into the third air duct section 4121 to achieve air circulation. Therefore, the filter 4124 on the air inlet 4125 of the third air duct section 4121 can effectively filter dust and other impurities in the air, ensuring that the air entering the air conditioner body 510 is cleaner, thereby effectively extending the service life of the air conditioner body 510 and improving the airflow circulation efficiency.
[0124] For example, the filter element 4124 may include, but is not limited to, a filter screen, a filter membrane, a filter cover, etc., and the embodiments disclosed herein do not limit this.
[0125] In some embodiments, referring to FIG17, the side of the duct component 400 facing the indoor side 310 includes an air outlet surface 411b and an air inlet surface 412b connected to the air outlet surface 411b. The air outlet surface 411b and the air inlet surface 412b are arranged at an angle, and the air outlet surface 411b is inclined towards the air inlet surface 412b, and the air inlet surface 412b is inclined towards the air outlet surface 411b, so that the duct component 400 forms a pointed side on the side facing the indoor side. The side of the duct component 400 facing the indoor side is the aforementioned second side 41b of the duct component 400. With this configuration, the size of the duct component 400 on the side facing the indoor side is smaller than the size of the side of the duct component 400 connected to the air conditioning body 510, thereby effectively reducing the space occupied by the duct component 400. Meanwhile, because the air outlet surface 411b and the air inlet surface 412b are set at an angle, and the air outlet surface 411b is tilted towards the air inlet surface 412b, the air outlet surface 411b can be positioned as high as possible towards the interior side 310, allowing the cold air to be blown upwards as much as possible, which is beneficial to improving the air circulation efficiency of the interior side 310. In addition, the air inlet surface 412b is tilted towards the air outlet surface 411b, and the air inlet surface 412b and the air outlet surface 411b form a sharp angle shape, so that the air inlet surface 412b and the air outlet surface 411b draw in and out in opposite directions, thereby reducing the problem of airflow crossing during intake and exhaust, and helping to increase the air outlet area and intake area, effectively improving the airflow circulation efficiency of the room.
[0126] In some embodiments, referring to FIG17, the included angle θ between the air outlet surface 411b and the air inlet surface 412b can be 90°-160°. For example, the included angle θ between the air outlet surface 411b and the air inlet surface 412b includes, but is not limited to, 90°-100°, 100°-110°, 110°-120°, 120°-130°, 130°-140°, 140°-150°, 150°-160°, etc. Exemplarily, the included angle θ between the air outlet surface 411b and the air inlet surface 412b includes, but is not limited to, 90°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, etc., and the embodiments disclosed herein do not limit this to such values.
[0127] In this embodiment, since the air outlet surface 411b and the air inlet surface 412b are located on the side of the duct component 400 facing the indoor side 310, by designing the included angle θ between the air outlet surface 411b and the air inlet surface 412b to be less than or equal to 160°, the side of the duct component 400 facing the indoor side 310 can be kept smaller, reducing the space occupied on the indoor side 310. In addition, it can also make the orientations of the air inlet surface 412b and the air outlet surface 411b as far apart as possible, thereby avoiding the problem of airflow crossing during intake and exhaust. By designing the included angle θ between the air outlet surface 411b and the air inlet surface 412b to be greater than or equal to 90°, the duct lengths of the air outlet duct 411 and the air inlet duct 412 can be appropriately increased, effectively improving the airflow circulation efficiency of the indoor side 310.
[0128] In some embodiments, as shown in Figures 13 and 22, the air duct component 400 includes a housing 41c, which is configured to be detachably connected to the air conditioner body 510. By providing a first latching part 413 on the housing 41c and engaging with a second latching part 513 on the air conditioner body 510, the installation and disassembly of the air duct component 400 are simple, time-saving, and labor-saving. At the same time, the housing 41c can also serve as a dustproof, moisture-proof, and decorative element.
[0129] In some embodiments, referring to FIG16, the air duct component 400 includes an air duct body 41d, which is disposed within a housing 41c. Referring to FIG23, the air duct body 41d includes an outlet air duct 411 and an inlet air duct 412. By disposing the outlet air duct 411 and the inlet air duct 412 within the housing 41c, the outlet air duct 411 and the inlet air duct 412 can be protected and shaped, thereby effectively preventing the outlet air duct 411 and the inlet air duct 412 from tilting or breaking due to impact from external objects, thus effectively improving the reliability of the air duct component 400.
[0130] In some embodiments, the material of the air duct body 41d includes expandable polystyrene. Expandable polystyrene is a material with thermal insulation, sound insulation, moisture resistance, and vibration damping properties. By using expandable polystyrene to make the air inlet duct 412 and air outlet duct 411, the heat loss of the condenser and evaporator of the air conditioner body 510 can be effectively reduced, and the thermal insulation effect, impact and vibration resistance, and sound insulation effect of the air duct body 41d can be enhanced, thereby effectively improving the energy efficiency of the air conditioner body 510.
[0131] In some embodiments, as shown in Figures 19 and 20, the upper surface 411c of the housing 41c along the height direction is provided with a positioning protrusion 412c. The positioning protrusion 412c is located at the edge of the upper surface 411c of the housing 41c and is configured to position the window frame 330 of the window sill 300 (see Figure 11, which shows the assembly relationship between the window sill 300, the air duct component 400, and the air conditioning body 510) on the housing 41c. By installing the air duct component 400 on the air conditioning body 510, and by providing a stepped structure on the upper surface 411c of the housing 41c to form the positioning protrusion 412c, and aligning the window frame 330 on the window sill 300 with the position of the positioning protrusion 412c, the user can achieve the installation alignment of the air duct component 400 according to the positioning protrusion 412c, thereby making the installation of the air duct component 400 easier.
[0132] In some embodiments, referring to Figures 14 and 23, the air duct component 400 further includes a control panel 16. The control panel 16 is located below the air outlet duct 411 in the height direction of the air duct component 400 and is configured to be electrically connected to the air conditioner body 510. The control panel 16 is configured to regulate various functions of the air conditioner body 510. Located on the air outlet surface 411b, the control panel 16 allows users to control the air conditioner body 510 from the indoor side 310. Its location below the air outlet duct 411 does not obstruct the air outlet direction, ensuring a higher air outlet position and improving the airflow circulation efficiency of the air conditioner body 510. The control panel 16 can be configured to control the air conditioner body 510 to perform various functions, such as adjusting temperature, operating mode, fan speed, and timer.
[0133] In some embodiments, referring to Figures 14 and 21, the air duct component 400 further includes an air guide plate 417, which is configured to be rotatably disposed at the air outlet 4113 of the air outlet duct 411 and can be configured to adjust the air outlet angle of the air outlet duct 411. Furthermore, the air guide plate 417 can also close the air outlet duct 411 when the air conditioner body 510 is not in use, effectively preventing dust and water droplets from entering the air outlet duct 411, thereby improving the reliability of the air conditioner body 510 and the air duct component 400.
[0134] In some embodiments, referring to FIG14, the control panel 416 is located below the air guide plate 417 in the height direction of the air duct component 400. This allows the control panel 416 to be set close to the air outlet 4113 of the air outlet duct 411. The control panel 416 is located between the air outlet duct 411 and the air inlet duct 412, which facilitates user operation and makes the design of the control panel 416 and the air outlet 4113 more compact, thereby improving the space utilization of the air duct component 400.
[0135] In some embodiments, referring to FIG14, the air outlet 4113 of the air outlet duct 411 has a first side 41131 and a second side 41132 opposite to each other along its width direction. The air guide plate 417 is rotatably connected to the first side 41131 and / or the second side 41132 and is located at the middle of the air outlet 4113 along its height direction. Compared with placing the air guide plate 417 at the top or bottom of the air outlet 4113, placing the air guide plate 417 at the middle of the air outlet 4113 and rotatably connecting it to the first side 41131 and the second side 41132 opposite to each other along its width direction allows for a larger rotation angle of the air guide plate 417 and provides better adjustment of the airflow blowing angle.
[0136] Although embodiments of this disclosure have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this disclosure, the scope of which is defined by the claims and their equivalents.
