[0042] Reference Figure 1 and Figure 2 As shown, a heat exchanger assembly 10 of an embodiment of the present invention includes a heat exchanger 100 and a fixed structure 200. Specifically, the heat exchanger 100 includes a first heat exchanger 110 and a second heat exchanger 120. The first heat exchanger 110 and the second heat exchanger 120 are arranged up and down and adjacent to each other. One end of the first heat exchanger 110 and one end of the second heat exchanger 120 are close to each other and the other end of the first heat exchanger 110 and the other end of the second heat exchanger 120 are far away from each other, thereby forming a V-shaped structure. A vent 130 is formed between the first heat exchanger 110 and the second heat exchanger 120. It should be noted that as one of the installation methods of the heat exchanger 100, the air entering from the air inlet 20 enters the first heat exchanger 110 and the second heat exchanger 120 from the vent 130 under the action of the wind wheel for heat exchange (such as Figure 1 As another installation method, the air entering the air inlet 20 is blown toward the first heat exchanger 110 and the second heat exchanger 120 under the action of the wind wheel, and is discharged from the vent 130 after heat exchange.

[0043] Further explanation is that, refer to Figure 2 and Figure 3 As shown, openings 140 are respectively provided on both sides of the vent 130, and the fixing structure 200 is located on at least one side of the heat exchanger 100, which can effectively prevent the vent 130 from leaking air to the opening 140.

The first heat exchanger 110 also includes a first elbow 112 (i.e., a refrigerant pipe elbow) extending outwardly along the first side plate 111. The number of the first elbows 112 is multiple and arranged at intervals, and the depth of the first groove 210 is greater than or equal to the height of the first elbow 112, ensuring that all the first elbows 112 can be accommodated in the first groove 210, and the side of the first heat exchanger 110 is better protected.

The first connecting edge 230 can be formed by folding processing, which is convenient to produce and has low cost.

[0046] Reference Figure 2 and Figure 4As shown, in some embodiments of the present invention, the second heat exchanger 120 includes a second side plate 121 disposed toward one side of the fixed structure 200, and the second groove 220 extends along the second side plate 121 and surrounds the entire second side plate 121. The second heat exchanger 120 also includes a second elbow 122 (i.e., a refrigerant pipe elbow) extending outwardly along the second side plate 121. The number of the second elbows 122 is multiple and arranged at intervals. The depth of the second groove 220 is greater than or equal to the height of the second elbow 122, ensuring that all the second elbows 122 can be accommodated in the second groove 220, and the side of the second heat exchanger 120 is better protected.

[0047] Reference Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments of the present invention, the upper edge of the second groove 220 is provided with a second connecting edge 240 extending away from the side of the first groove 210, that is, the second connecting edge 240 extends away from the opening 140, and the second connecting edge 240 is fixedly connected to the second side plate 121.

It should be noted that the connecting plate 250 connects the first groove 210 and the second groove 220 into one body, thereby improving the structural strength between the two. Figure 3 As shown, the connecting plate 250 is fixedly connected to the first side plate 111 and the second side plate 121 , which can not only fix the first heat exchanger 110 and the second heat exchanger 120 to improve the connection strength between the two, but also seal the opening 140 to improve the heat exchange efficiency of the heat exchanger 100 .

[0049] Further explanation is that, refer to Figure 4 and Figure 5 As shown, the mounting structure formed between the first connecting edge 230, the second connecting edge 240 and the connecting plate 250 enables the fixing structure 200 to be fixed to the heat exchanger 100 by six screws, which can greatly improve the efficiency of assembly. In addition, the mounting structure is stable and has a long service life, and can protect the refrigerant pipe bends of the heat exchanger 100 in all directions.

In addition, in order to reduce the impact on the air intake of the air duct 40, the reinforcing rib 260 is provided on the outer side of the connecting plate 250, that is, the side facing away from the vent 130.

[0051] Further, in some embodiments of the present invention, the two ends of the reinforcing rib 260 extend toward the first groove 210 and the second groove 220 respectively, so that the connecting plate 250 has sufficient anti-bending ability, and the structural strength of the connecting plate 250 is further improved. It can be understood that the reinforcing rib 260 cooperates with the first groove 210 and the second groove 220 to form a triangular structure, which further strengthens the strength of the fixing structure 200 and makes the structure of the heat exchanger 100 more stable.

[0052] Reference Figure 4 As shown, in some embodiments of the present invention, a first guide port 211 is provided at the lower end of the first groove 210 extending along the length direction of the first heat exchanger 110.
