The heat exchanger 1 comprises a plurality of layers of pipe joints 11, each layer of pipe joint 11 is connected with a layer of heat exchange pipe, and the arrangement direction between the layers of the plurality of layers of pipe joints 11 is the interlayer arrangement direction. The edge plate group 2 includes a plurality of edge plates 20 for fixing the above-described multi-layered pipe joint 11, and the plurality of edge plates 20 are arranged in the direction of the inter-layer arrangement. Since the first fixing portions 310 and the second fixing portions 320 of the fixing member 3 are also provided at intervals in the interlayer arrangement direction, the fixing member 3 has a certain span in the interlayer arrangement direction. Since the first fixing portion 310 is connected to at least one side panel 20 of the side panel group 2 and the second fixing portion 320 is connected to at least another side panel 20 of the side panel group 2, at least two side panels 20 of the side panel group 2 can be indirectly connected by the fixing member 3, and the side panels 20 indirectly connected by the fixing member 3 are not necessarily disposed adjacent to each other. In this way, each fixing member 3 is fixedly connected with at least two side plates 20 in the side plate group 2, and the side plates 20 in the side plate group 2 can be indirectly fixed through at least one fixing member 3 without being fastened with the side plates 20 adjacent to the two sides through screws. Therefore, the fixing process of the side plate 20 is simplified, and the assembling efficiency of the heat exchanger assembly 100 is improved.

It is understood that the present embodiment defines the arrangement direction between the layers of the pipe joint 11 as the interlayer arrangement direction. In fig. 1, the interlayer alignment direction refers to the left-right direction.

In an exemplary embodiment, the sideboard 20 comprises a first flap 21, a sideboard body 23 and a second flap 22 connected in series, as shown in fig. 3, and the first flap 21, the sideboard body 23 and the second flap 22 enclose a receiving groove 24.

Each layer of pipe joints 11 comprises a plurality of pipe joints 11 arranged at intervals along the up-down direction, namely, the arrangement direction in the layer of each layer of pipe joints 11 is the vertical direction. The pipe joint 11 is an elbow joint.

The two edge plate groups 2 are arranged at intervals along the vertical direction. Each edge plate group 2 includes three edge plates 20, and the three edge plates 20 are arranged in the left-right direction. Each edge panel 20 includes a first flange 21, an edge panel body 23, and a second flange 22, which are connected in series. The bending height of the first folded edge 21 is smaller than that of the second folded edge 22. The first flap 21 is provided with a first fitting hole 211 and the second flap 22 is provided with a second fitting hole 221. The sideboard body 23 is provided with a mounting hole 231, and the pipe joint 11 is in interference fit with the mounting hole 231. The three side plates 20 in each side plate group 2 are closely arranged along the left-right direction, as shown in fig. 6, six side edges are sequentially from left to right: a first folded edge 21, a second folded edge 22, and a first folded edge 21. In other words, the second folded edge 22 of the side panel 20 positioned on the left side is arranged to be stacked on the first folded edge 21 of the side panel 20 positioned in the middle, and the second folded edge 22 of the side panel 20 positioned in the middle is arranged to be stacked on the second folded edge 22 of the side panel 20 positioned on the right side.

Each fixing member 3 includes a first fixing plate 31, a connecting plate 33, and a second fixing plate 32, which are connected in sequence. The bending height of the first fixing plate 31 is greater than that of the second fixing plate 32, that is, the dimension of the first fixing plate 31 in the thickness direction of the sideboard body 23 is greater than that of the second fixing plate 32 in the thickness direction of the sideboard body 23. The first fixing plate 31 is provided with a first fixing hole 311, the second fixing plate 32 is provided with a second fixing hole 321, and the connecting plate 33 is provided with a viewing hole 331. The fixing member 3 may also be called a fixing clip.

Each first fastening plate 31 is fixedly connected to the first fold 21 of the left-hand edge plate 20, and each second fastening plate 32 is fixedly connected to the two second folds 22 arranged one above the other. Also, the two second flanges 22 arranged in a stack are also pre-fixed by screws. In this way, three edge plates 20 in one edge plate group 2 are fixed.

The fixing mode of the side plate 20 of this embodiment does not require the high folding height of both folding edges of the side plate 20, so that the die cost and the material cost of the side plate 20 can be reduced, and the product cost can be reduced.

In summary, the heat exchanger assembly and the air conditioner provided by the embodiment of the utility model are additionally provided with the fixing piece for connecting the side plate, so that the fixing process of the side plate is simplified, the assembly efficiency is improved, and the bending height of one folded edge of the side plate can be reduced, thereby reducing the die cost and the material cost of the side plate and reducing the product cost.
