[0047] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0048] Reference below Figure 1-Figure 13 A heat exchanger assembly 100 for an air conditioner indoor unit 1000 according to an embodiment of the first aspect of the present invention is described.

[0049] like Figure 4 and Figure 5As shown, the heat exchanger assembly 100 according to the first embodiment of the utility model includes: a heat exchange element 10 and a sealing plate 20.

[0050] Specifically, the heat exchange element 10 includes a plurality of heat exchange elements 10 in the width direction (eg Figure 4 The first heat exchange part 11 and the second heat exchange part 12 are arranged at an angle (in the front-to-back direction shown in FIG. 1 ), and one end of the first heat exchange part 11 (for example Figure 4 The upper end of the first heat exchange portion 11 shown in FIG. 1 and one end of the second heat exchange portion 12 (for example Figure 4 The sealing plate 20 is fixed on the heat exchange element 10 and seals the gap between the first heat exchange portion 11 and the second heat exchange portion 12.

[0051] For example, the sealing plate 20 can be fixed to the first heat exchange part 11 and / or the second heat exchange part 12. Specifically, the sealing plate 20 can be fixed to the first heat exchange part 11 and the second heat exchange part 12 by clamping, riveting, bonding and / or fasteners.

[0052] like Figure 4 As shown, the heat exchange element 10 includes a first heat exchange portion 11 and a second heat exchange portion 12, and the first heat exchange portion 11 and the second heat exchange portion 12 are arranged in the front-to-back direction, and the first heat exchange portion 11 extends upwardly obliquely in the direction from the back to the front, and at least a portion of the second heat exchange portion 12 extends upwardly obliquely in the direction from the front to the back, and the upper end of the first heat exchange portion 11 is connected to the upper end of the second heat exchange portion 12, and the first heat exchange portion 11 and the second heat exchange portion 12 enclose a space for arranging a fan assembly and a heater, and the fan assembly and the heater, etc. can be arranged on the lower side of the first heat exchange portion 11 and the second heat exchange portion 12.

[0053] In order to prevent the air entering the shell 200 from the air inlet from passing through the gap between the first heat exchange part 11 and the second heat exchange part 12 and entering the position of the fan assembly, the present embodiment provides a sealing plate 20 for sealing the gap between the first heat exchange part 11 and the second heat exchange part 12, thereby ensuring that the air entering the shell 200 from the air inlet can exchange heat with the first heat exchange part 11 or the second heat exchange part 12 and then flow to the downstream fan assembly and air outlet, thereby improving the heat exchange efficiency of the air-conditioning indoor unit 1000.

[0054] An air inlet is formed at the top of the shell 200, and a filter element 300 is provided at the air inlet position of the shell 200. The filter element 300 can be a filter net, which covers the air inlet position and is used to filter dust and impurities in the air entering from the air inlet, thereby improving the air quality blown out by the air-conditioning indoor unit 1000.

[0055] In one example, the filter element 300 is detachably connected to the shell 200. Specifically, a filter guide rail 2021 is provided in the shell 200. The filter guide rail 2021 is formed on the face frame 202 of the shell 200. The filter guide rail 2021 includes a first guide rail section and a second guide rail section. The first guide rail section is formed on the top wall of the shell 200 and extends forward and backward. The second guide rail section is connected to the front end of the first guide rail section and is formed on the front wall of the shell 200 and extends up and down. The two side edges of the filter screen slide in cooperation with the filter guide rail 2021.

[0056] In the prior art, the first heat exchange part 11 and the second heat exchange part 12 are sealed by a sponge member. When the heat exchanger assembly 100 is assembled into the shell 200 from back to front, the first guide rail section of the filter guide rail or other structures on the top wall of the shell 200 can easily scratch the sponge, causing the sealing of the sponge member to fail.

[0057] In the present application, a sealing plate 20 is provided to seal the gap between the first heat exchange part 11 and the second heat exchange part 12. The sealing plate 20 occupies a smaller space, and the surface of the sealing plate 20 is smoother than that of the sponge part. The sealing plate 20 has a higher structural strength, thereby effectively reducing the probability of interference between the sealing plate and the structure of the top wall of the shell 200 (such as the filter guide rail 2021, etc.), thereby improving the sealing effect of the sealing plate, increasing the service life of the sealing plate, and improving the assembly efficiency of the air-conditioning indoor unit 1000.

[0058] According to the heat exchanger assembly 100 of the embodiment of the utility model, by providing a sealing plate 20 for sealing the gap between the first heat exchange part 11 and the second heat exchange part 12, the probability of structural interference between the sealing plate 20 and the top wall of the air-conditioning indoor unit 1000 can be reduced, the sealing effect and service life of the sealing plate can be improved, the assembly efficiency of the air-conditioning indoor unit 1000 can be improved, the probability of abnormal sounds and noise problems in the air-conditioning indoor unit 1000 can be reduced, and the heat exchange performance in the air-conditioning room can be improved.

[0059] In one embodiment of the present invention, the sealing plate 20 is a plastic part, thereby not only reducing the weight of the sealing plate 20 but also reducing the cost.

[0060] In one embodiment of the present invention, Figure 5-Figure 8 As shown, the sealing plate 20 may include a sealing main board 21 and a fixing portion 22. The sealing main board 21 is in the shape of a plate extending along the length direction of the heat exchanger 10 (for example, the left and right direction shown in 3). The fixing portion 22 is connected to the sealing main board 21 and is detachably connected to the first heat exchange portion 11 and / or the second heat exchange portion 12.

[0061] For example, the sealing main board 21 is a long strip extending in the left-right direction, so that the gap between the first heat exchange part 11 and the second heat exchange part 12 can be effectively sealed within the length of the heat exchange element 10. Further, the fixing part 22 is connected to the sealing main board 21, for example, the fixing part 22 can be integrally formed with the sealing main board 21, so that the number of parts can be reduced and the connection reliability between the fixing part 22 and the sealing main board 21 can be improved.

[0062] The fixing part 22 may be fixed only on the first heat exchange part 11 and detachably connected to the first heat exchange part 11, the fixing part 22 may be fixed only on the second heat exchange part 12 and detachably connected to the second heat exchange part 12, or the fixing part 22 may be fixed on both the first heat exchange part 11 and the second heat exchange part 12 and detachably connected to both the second heat exchange part 12 and the first heat exchange part 11. The fixing part 22 and the first heat exchange part 11 and / or the second heat exchange part 12 may be connected by snapping or by fasteners.

[0063] In this embodiment, the sealing plate 20 includes a sealing main board 21 and a fixing portion 22. The sealing main board 21 can achieve the effect of sealing the gap between the first heat exchange portion 11 and the second heat exchange portion 12. The fixing portion 22 can reliably fix the sealing plate 20 on the heat exchanger 10, and the fixing portion 22 is detachably connected to the first heat exchange portion 11 or the second heat exchange portion 12, which can improve the assembly efficiency between the sealing plate 20 and the heat exchanger 10 and facilitate maintenance and replacement.

[0064] In one embodiment of the present invention, the sealing main board 21 is arranged on the end surface of one end of the first heat exchange part 11 and one end of the second heat exchange part 12, and the side surface of the sealing main board 21 facing away from the heat exchanger 10 is formed as a guide surface 211, and the guide surface 211 is a convex surface protruding away from the heat exchanger 10.

[0065] For example, Figure 8 , Fig.11 and Fig.12 As shown, the sealing main board 21 is arranged on the upper side surface of the first heat exchange part 11 and the second heat exchange part 12, and the upper side surface of the sealing main board 21 is formed as a guide surface 211. The guide surface 211 is configured to play a guiding role when the heat exchanger assembly 100 is installed into the face frame 202 of the shell 200 from the back to the front, and to play a guiding role when the heat exchanger assembly 100 is taken out of the face frame 202 from the front to the back. Specifically, in the front-to-back direction, the guide surface 211 is formed as a convex surface that protrudes upward, that is, in the front-to-back direction, the guide surface 211 first extends upwardly and then extends downwardly.

[0066] In this way, the front section of the guide surface 211 is inclined forward and downward, and when the heat exchanger assembly 100 is installed in the face frame 202, it plays a role in positioning and guiding, improving the efficiency of the heat exchanger assembly 100 being installed in the face frame 202, and effectively avoiding the interference and scratching between the sealing plate 20 and the top wall of the face frame 202. The rear section of the guide surface 211 is inclined backward and downward, and when the heat exchanger assembly 100 is taken out of the face frame 202, it is convenient for the sealing plate 20 to extend out of the face frame 202, and avoid the sealing plate 20 from hitting the upper edge of the rear end of the face frame 202.

[0067] In this embodiment, the surface of the sealing main board 21 facing away from the heat exchanger 10 is formed into a raised guide surface 211. The guide surface 211 can play a guiding role when the heat exchanger assembly 100 is installed in and removed from the face frame 202, thereby improving assembly efficiency.

[0068] In one embodiment of the present invention, the guide surface 211 may include a width direction (eg Figure 8 The first guide segment 2111 and the second guide segment 2112 are connected in the front-to-back direction (as shown in FIG. 1 ), and the first guide segment 2111 and the second guide segment 2112 are planes extending toward each other and connected in a circular arc.

[0069] Specifically, the first guide segment 2111 and the second guide segment 2112 are arranged front to back, and the first guide segment 2111 is connected to the rear side of the second guide segment 2112. In the direction from back to front, the first guide segment 2111 is a plane extending upwardly inclined, and the second guide segment 2112 is a plane extending downwardly inclined.

[0070] In this way, the guide surface 211 can be simplified under the premise of playing a guiding role, and the processing and manufacturing are convenient. In addition, the first guide segment 2111 and the second guide segment 2112 are connected in an arc, which can make the guide surface 211 smooth, avoid the formation of a sharp area on the upper surface of the sealing main board 21, and further avoid the sealing main board 21 scratching the top structure of the face frame 202.

[0071] In one example, in the direction from back to front, the thickness of the sealing main board 21 gradually increases and then gradually decreases, so that the guide surface 211 can be easily formed, which is beneficial for guiding when the heat exchanger assembly 100 is installed in the face frame 202 and simplifying the structure.

[0072] In one embodiment of the present invention, Figure 6 and Figure 7 As shown, the sealing plate 20 also includes a first guide lug 23 and a second guide lug 24, which are respectively connected to the two side edges of the sealing main board 21 in the width direction, and extend downwardly in directions away from each other, and the fixing portion 22 is connected to the first guide lug 23, the second guide lug 24 and the sealing main board 21.

[0073] like Figure 6 As shown, the first guide lug 23 is in the shape of a flat plate, one end of which is connected to the rear edge of the sealing main board 21, and the other end extends downward and backward, and the second guide lug 24 is in the shape of a flat plate, one end of which is connected to the front edge of the sealing main board 21, and the other end extends forward and downward.

[0074] The first guide lug 23 and the second guide lug 24 may be arranged relative to each other in the width direction of the sealing main board 21, and further, the first guide lug 23 and the second guide lug 24 may be arranged symmetrically with respect to the sealing main board 21. The fixing portion 22 may be arranged at the connection position between the sealing main board 21 and the first guide lug 23 and the second guide lug 24. For example, the first guide lug 23, the second guide lug 24 and the portion of the sealing main board 21 directly facing the first guide lug 23 and the second guide lug 24 may together constitute a guide area of ​​the sealing plate 20, and the fixing portion 22 may be provided in the guide area and fixedly connected to the guide area.

[0075] Thus, the first guide lug 23 and the second guide lug 24 can guide the heat exchanger assembly 100 when it is inserted into and removed from the face frame 202, further improving the assembly efficiency of the air conditioner indoor unit 1000. At the same time, the first guide lug 23 and the second guide lug 24 can increase the width of the sealing plate 20 in the front-to-back direction, so that the fixing part 22 can be arranged conveniently without increasing the width of the sealing main board 21, and the fixing part 22 can be conveniently connected to the first heat exchange part 11 and the second heat exchange part 12, and the material consumption of the sealing main board 21 can be reduced, thereby reducing the cost. In addition, the first guide lug 23 and the second guide lug 24 can also improve the structural strength of the sealing plate 20.

[0076] In one embodiment of the utility model, the number of the first guide lugs 23 and the second guide lugs 24 are both multiple, and are arranged at intervals along the length direction of the sealing plate 20. That is, the number of the first guide lugs 23 can be two, three, four, five, six or more, and the multiple first guide lugs 23 are arranged at intervals along the left-right direction, and the number of the second guide lugs 24 can be two, three, four, five, six or more, and the multiple second guide lugs 24 are arranged at intervals along the left-right direction. In this way, the structural strength of the sealing plate 20 can be further enhanced, and the guiding effect during assembly can be further improved.

[0077] For example Figure 6As shown, three first guide lugs 23 are provided on the rear edge of the sealing main board 21, wherein two first guide lugs 23 are arranged at the two ends of the sealing main board 21 in the left-right direction, and are respectively flush with the end edges of the left and right ends of the sealing main board 21, and another first guide lug 23 is arranged in the middle position of the sealing main board 21 in the left-right direction, and three second guide lugs 24 are provided on the front edge of the sealing main board 21, wherein two second guide lugs 24 are arranged at the two ends of the sealing main board 21 in the left-right direction, and are respectively flush with the end edges of the left and right ends of the sealing main board 21, and another second guide lug 24 is arranged in the middle position of the sealing main board 21 in the left-right direction.

[0078] The first guide lug 23 and the second guide lug 24 are located in a vertical direction opposite to the filter guide rail 2021 on the face frame 202 of the housing 200. In this way, the filter guide rail 2021 can be further prevented from interfering with the sealing plate 20, thereby improving assembly efficiency.

[0079] In one embodiment of the present invention, Figure 8 As shown, the fixing portion 22 includes a first clamping portion 221 and a second clamping portion 222 . The first clamping portion 221 is clamped and connected to the first heat exchange tube 111 of the first heat exchange portion 11 , and the second clamping portion 222 is clamped and connected to the second heat exchange tube 121 of the second heat exchange portion 12 . In this way, the first clamping portion 221 can be used to realize the clamping connection between the sealing plate 20 and the first heat exchange portion 11, and the second clamping portion 222 can be used to realize the clamping connection between the sealing plate 20 and the second heat exchange portion 12. As a result, the first heat exchange portion 11 and the second heat exchange portion 12 can be clamped and connected at the same time, thereby improving the stability and reliability of fixing the sealing plate 20, and the clamping connection can also improve the assembly efficiency of the sealing plate 20. In addition, the first clamping portion 221 is clamped with the first heat exchange tube 111, and the second clamping portion 222 is clamped with the second heat exchange tube 121, which not only simplifies the structure of the first clamping portion 221 and the second clamping portion 222, but also does not need to add a clamping structure to the heat exchange component 10, and the structure is simple and easy to operate.

[0080] In one embodiment of the present invention, Figure 8 As shown, the first clamping portion 221 is formed in a plate shape, and a first clamping groove 2211 for clamping the first heat exchange tube 111 is provided on one side edge of the first clamping portion 221 in the width direction of the sealing main board 21. For example, the upper end of the first clamping portion 221 is connected to the sealing main board 21, the lower end of the first clamping portion 221 extends downward, and the first clamping portion 221 is formed in a plate shape arranged perpendicular to the left and right directions, and a first clamping groove 2211 is formed on the rear side edge of the first clamping portion 221, and the first heat exchange tube 111 can be clamped into the first clamping groove 2211.

[0081] The first clamping slot 2211 may be formed by a depression on the rear edge of the first clamping portion 221 , or two convex portions spaced apart may be provided on the rear edge of the first clamping portion 221 , and the two convex portions cooperate to define the first clamping slot 2211 .

[0082] In this embodiment, by providing a first clamping groove 2211 on one side edge of the plate-shaped first clamping portion 221 , the structure of the first clamping portion 221 can be simplified to facilitate processing and manufacturing while achieving clamping connection with the first heat exchange tube 111 .

[0083] In one embodiment of the present invention, Figure 8 As shown, in the direction from the sealing main board 21 toward the heat exchanger 10, the first clamping portion 221 extends obliquely away from the second heat exchange portion 12, and the first clamping groove 2211 is formed by a concave edge of the first clamping portion 221 away from the second heat exchange portion 12. Figure 8 As shown, the rear edge of the first clamping portion 221 extends downward and backward, and the first clamping groove 2211 is formed by the forward depression of the rear edge of the first clamping portion 221. Furthermore, the first clamping groove 2211 is a semicircular groove, and the shape of the first clamping groove 2211 is adapted to the shape of the first heat exchange tube 111.

[0084] By extending the first clamping portion 221 obliquely away from the second clamping portion 222 in this embodiment, the first clamping portion 221 can be easily inserted between two adjacent first heat exchange tubes 111, and the first clamping portion 221 and the first heat exchange tube 111 away from the second clamping portion 222 can be clamped together, thereby improving the assembly efficiency of the first clamping portion 221 and the first heat exchange tube 111 and improving the reliability of the connection between the first clamping portion 221 and the first heat exchange tube 111.

[0085] In an embodiment of the present invention, the second clamping portion 222 is in the shape of a plate extending toward the heat exchanger 10 , and a second clamping groove 2221 for clamping the second heat exchange tube 121 is provided on one side edge of the second clamping portion 222 away from the sealing plate 20 .

[0086] like Figure 8 As shown, the second clamping portion 222 is in the shape of a plate arranged perpendicular to the left and right directions, the upper end of the second clamping portion 222 is connected to the sealing main board 21, the lower end of the second clamping portion 222 extends downward toward the heat exchanger 10, and the lower side edge of the second clamping portion 222 is formed with a second clamping groove 2221 that is recessed upward, and the second clamping portion 222 clamps the second heat exchange tube 121 in the second clamping groove 2221.

[0087] When assembling the sealing plate 20 and the heat exchanger 10, the sealing plate 20 can be placed on the top of the heat exchanger 10 first, and then the sealing plate 20 can be pressed down from top to bottom to make the second heat exchange tube 121 clamped into the second clamping groove 2221. As a result, the clamping operation is simple and convenient, and the assembly efficiency between the second clamping portion 222 and the second heat exchange tube 121 can be improved.

[0088] In one embodiment of the utility model, a guide groove 2222 is also formed on the second clamping portion 222, and the guide groove 2222 is connected to the side of the second clamping portion 2221 away from the sealing plate 20 and passes through the edge of the side of the second clamping portion 222 away from the sealing main board 21, and the width of the guide groove 2222 gradually increases in the direction from the second clamping slot 2221 toward the guide groove 2222.

It is ensured that the sealing plate 20 can be smoothly clamped with the first heat exchange portion 11 and the second heat exchange portion 12 at the same time, thereby improving the assembly efficiency.

[0092] In an embodiment of the present invention, an opening 2223 is further formed on the second holding portion 222 . The opening 2223 is connected to a side of the second slot 2221 facing the sealing main board 21 and extends toward the sealing main board 21 in a long strip shape.

[0093] like Figure 8 As shown, the second clamping portion 222 is a plate body arranged perpendicular to the left-right direction, and an opening 2223 is formed on the second clamping portion 222, and the opening 2223 penetrates the second clamping portion 222 in the left-right direction, and the opening 2223 is a long strip hole extending in the up-down direction, and the upper end of the opening 2223 extends to close to the sealing main board 21, and the lower end of the opening 2223 extends to the upper edge of the second clamping groove 2221, and penetrates the upper edge of the second clamping groove 2221 to communicate with the second clamping groove 2221.
