[0042] Figure 1 is a schematic front view of a heat exchanger assembly according to an embodiment of the utility model, such as Figure 1 As shown, and refer to Figures 2 to 9 The embodiment of the utility model provides a heat exchanger assembly for an air conditioner. The heat exchanger assembly includes an air duct skeleton 200 and a heat exchanger 100 .

[0043] The air duct frame 200 includes an upper tray 210 and a lower tray 220 arranged vertically at intervals. The upper surface of the lower tray 220 is provided with a mounting groove 221 with an opening facing upward.

[0044] The heat exchanger 100 includes a body 101 and a refrigerant inlet and outlet pipe 120. The body 101 is vertically arranged, the lower end of the body 101 is inserted into the mounting groove 221, and the upper end of the body 101 is fixedly connected to the rear side of the upper tray 210. The refrigerant inlet and outlet pipe 120 extends forward from the front end of the body 101 and extends downward. The lower end of the refrigerant inlet and outlet pipe 120 is located at the lower side of the lower tray 220, and the refrigerant inlet and outlet pipe 120 is located between the lateral ends of the lower tray 220 in the lateral direction.

[0045] On a horizontal projection plane, the mounting groove 221 and the body 101 are both U-shaped with the opening facing forward, and the distance between the first edge 2211 on the rear side of the mounting groove 221 and the refrigerant inlet and outlet pipe 120 is greater than the distance between the first edge 2211 and the front end of the lower tray 220. In other words, the refrigerant inlet and outlet pipe 120 is located at the front side of the lower tray 220.

[0046] like Figure 4 As shown, when installing the heat exchanger 100 on the air duct frame 200, the lower end of the refrigerant inlet and outlet pipe 120 is placed at the front end of the lower tray 220, and the lower end of the main body 101 is inserted into the installation groove 221, and then the main body 101 is rotated to cover the rear side of the air duct frame 200, so that the upper end of the main body 101 is fixedly connected to the rear side of the upper tray 210.

[0047] In this embodiment, the rear surface of the upper tray 210 located at the front side of the body 101 cooperates with the upper end profile of the concave surface of the body 101, so as to stop the upper end of the body 101 when the body 101 is rotated to cover the rear side of the air duct frame 200. Further, a seal is provided on the upper tray 210, and the seal forms the rear surface of the upper tray 210, which cooperates with the upper end profile of the concave surface of the body 101. Since the refrigerant inlet and outlet pipes 120 are located between the lateral ends of the lower tray 220 in the lateral direction, and the refrigerant inlet and outlet pipes 120 need to be installed on the front side of the lower tray 220, the heat exchanger 100 cannot be directly covered on the air duct frame 200 from the rear side. Compared with a heat exchanger assembly that requires the heat exchanger 100 to be first installed on an upper tray or a lower tray and then the upper tray and the lower tray are connected by a connecting piece, the utility model directly rotatably installs the heat exchanger 100 on the air duct frame 200, thereby simplifying the installation steps of the heat exchanger 100 and improving the installation efficiency.

[0048] Preferably, in some embodiments of the heat exchanger assembly of the utility model, the connecting piece connecting the upper tray 210 and the lower tray 220 can be two connecting columns 230. The upper tray 210, the lower tray 220 and the two connecting columns 230 of the air duct skeleton 200 are an integrated structure. Setting some parts of the heat exchanger assembly as an integrated structure reduces the number of parts that need to be assembled when installing the heat exchanger assembly, reduces the difficulty of the assembly process, and improves the production efficiency of the heat exchanger assembly. In addition, the utility model solves the problem of how to install the heat exchanger 100 when the upper tray 210, the lower tray 220 and the two connecting columns 230 are an integrated structure. Compared with the heat exchanger assembly that requires the heat exchanger 100 to be first installed on the upper tray 210 or the lower tray 220, and then the upper tray 210 and the lower tray 220 are connected by a connecting piece, this embodiment improves the production efficiency of the heat exchanger assembly while improving the installation efficiency of the heat exchanger assembly.

In addition, the top plate 211 fixedly connected to the upper tray 210 can improve the strength of the upper tray 210 to better protect the body 101 of the heat exchanger 100.

[0051] In some embodiments of the heat exchanger assembly of the present invention, Figure 4 and Figure 5 As shown, the lower surface of the top plate 211 is provided with an arc-shaped avoidance groove 212 with the first edge 2211 as the axis, and the radius of the arc-shaped avoidance groove 212 is greater than the distance between the first edge 2211 and the second edge 1011 at the front end of the upper end of the body 101.

[0052] In this embodiment, in order to improve the compactness of the heat exchanger assembly and reduce the volume occupied inside the indoor unit of the air conditioner, the top plate 211 can be arranged close to the top of the heat exchanger 100. In addition, an arc-shaped avoidance groove 212 is arranged on the lower surface of the top plate 211 to prevent the top plate 211 from interfering with the second edge 1011 of the body 101 when the body 101 is rotated and covered on the rear side of the air duct frame 200, so as to ensure that the body 101 is smoothly installed on the air duct frame 200.

Each side mounting member 110 includes an end plate 113, a first flange 111, and a second flange 112. The end plate 113 is arranged vertically, and the heat exchange tubes of the heat exchanger 100 pass through the end plate 113. The first flange 111 is connected to the vertical edge of one side of the end plate 113 adjacent to the corresponding connecting column 230 to form a first connecting bracket. The second flange 112 is connected to the vertical edge of the other side of the end plate 113, and the first flange 111 and the second flange 112 are located on both sides of the end plate 113.

[0057] In this embodiment, a through hole corresponding to the first connection hole is provided on the first flange 111, so that the heat exchanger 100 can be connected to the connection column 230 by bolts. Preferably, there are multiple first connection holes, and the multiple first connection holes are evenly and spaced apart in the vertical direction. The second flange extends in the direction of the main body 101 to improve the connection stability between the edge mounting member 110 and the heat exchanger 100. Moreover, the second flange 112 shields the front end of the main body 101, thereby protecting the main body 101. Alternatively, the second flange can also extend in a direction away from the main body 101 to improve the strength of the edge mounting member 110.

[0058] Furthermore, a sealing strip extending along the length direction of the first flange 111 is connected to the first flange 111 , and the sealing strip is fixedly connected to the connecting column 230 .

[0060] In this embodiment, the heat exchanger 100 is connected to the lower side of the top plate 211 through the cooperation between the second connecting bracket 114 and the second connecting hole.

[0061] In some embodiments of the heat exchanger assembly of the present invention, a third connection hole is vertically arranged at the front side of the installation groove 221 , and a third connection bracket 115 corresponding to the third connection hole is arranged at the lower end of the body 101 .

[0062] In this embodiment, the heat exchanger 100 is connected to the upper side of the lower tray 220 through the cooperation between the third connecting bracket 115 and the third connecting hole.

[0063] Furthermore, if Figure 7 and Figure 8 As shown, a second connecting bracket 114 extending outward is fixedly connected to the upper side of each vertical edge mounting member 110 , and a third connecting bracket 115 extending outward is fixedly connected to the lower side.

[0064] In some embodiments of the heat exchanger assembly of the present invention, Figure 3 As shown, the heat exchanger assembly further includes a protection structure 240, which extends forward from the front end of the lower tray 220 to form a slot. The opening of the slot is arranged forward.

[0065] When installing the heat exchanger 100 on the air duct frame 200, insert the refrigerant inlet and outlet pipes 120 into the slot, and insert the lower end of the main body 101 into the installation slot 221. Then, the main body 101 is rotated around the lower end of the main body 101 and the cover is installed on the rear side of the air duct frame 200, so that the upper end of the main body 101 is fixedly connected to the rear side of the upper tray 210.

[0066] In this embodiment, the protective structure 240 limits the refrigerant inlet and outlet pipes 120 to prevent the position of the heat exchanger 100 from deviating during the rotation installation or transportation of the heat exchanger 100. It also protects the refrigerant inlet and outlet pipes 120 and reduces the possibility of bending of the refrigerant inlet and outlet pipes 120.

[0067] In some embodiments of the heat exchanger assembly of the present invention, Fig. 9 As shown, at least one wind wheel mounting structure 260 for mounting a wind wheel of a crossflow blower is disposed on the upper tray 210 .
