DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The principles and features of the present application will be described below with reference to the drawings. The examples given are only used to explain the present application and are not intended to limit the scope of the present application.

[0023] The outdoor unit of the air conditioner provided by the embodiment of the present application includes a combined module. As shown in Figures 1 to 5As shown, the combined module includes: a shell-and-tube heat exchanger 100, which is spirally arranged in the vertical direction and encloses an accommodation cavity 140; and a gas-liquid separator 200, which is arranged in the accommodation cavity 140 and fixedly connected to the shell-and-tube heat exchanger 100.

[0024] The shell-and-tube heat exchanger is spirally arranged in the vertical direction and encloses an accommodation cavity 140. The gas-liquid separator 200 is arranged in the accommodation cavity 140, and the space inside the accommodation cavity 140 is utilized. In this way, when the combined module is installed on the chassis of the outdoor unit of the air conditioner, the layout space required on the chassis can be reduced; moreover, the shell-and-tube heat exchanger 100 and the gas-liquid separator 200 are delivered as a combined module. In this way, when the combined module is installed on the chassis, the operation of installing the gas-liquid separator 200 is omitted, and the assembly efficiency of the outdoor unit of the air conditioner can be improved.

[0025] In some examples, such as Figures 1 to 5 As shown, the combined module further includes: a liquid storage tank 300, which is arranged in the accommodation cavity 140 and fixedly connected to the shell-and-tube heat exchanger 100.

[0026] The liquid storage tank 300 is also arranged in the accommodation cavity 140, and the space inside the accommodation cavity 140 is also utilized. In this way, when the combined module is installed on the chassis of the outdoor unit of the air conditioner, the layout space required on the chassis can be further reduced; moreover, the shell-and-tube heat exchanger 100, the liquid storage tank 300 and the gas-liquid separator 200 are delivered as a combined module, and the operations of installing the liquid storage tank 300 and the gas-liquid separator 200 are omitted, and the assembly efficiency of the outdoor unit of the air conditioner can be improved.

[0027] In some examples, such as Figures 1 to 5 As shown, the combined module further includes: a first bracket 110, which is arranged in the accommodation cavity 140 and fixedly connected to the shell-and-tube heat exchanger 100; a second bracket 210, which is arranged on the gas-liquid separator 200 and fixedly connected to the first bracket 110; and a third bracket 310, which is arranged on the liquid storage tank 300 and fixedly connected to the first bracket 110, so as to assemble the shell-and-tube heat exchanger 100, the gas-liquid separator 200 and the liquid storage tank 300 together. This solution has a simple structure and is easy to operate.

[0028] In some embodiments, such as Figures 1 to 5As shown, the gas-liquid separator 200, the liquid storage tank 300, the first bracket 110, the second bracket 210, and the third bracket 310 are all vertically arranged. And in the horizontal direction: the second bracket 210 is located between the gas-liquid separator 200 and the first bracket 110, and the third bracket 310 is located between the liquid storage tank 300 and the first bracket 110, so that the space utilization rate inside the installation cavity is higher. Among them, the shell-and-tube heat exchanger 100, the gas-liquid separator 200, and the liquid storage tank 300 are spaced apart from each other to prevent direct contact and heat transfer between the shell-and-tube heat exchanger 100, the gas-liquid separator 200, and the liquid storage tank 300, so that the operating efficiency of the outdoor unit of the air conditioner is better.

[0029] In some embodiments, as Figures 1 to 5 shown, the shell-and-tube heat exchanger 100 has a refrigerant flow path 120 and a water flow path 130. The refrigerant flow path 120 passes through the water flow path 130. The lower end of the refrigerant flow path 120 has a first interface 121, and the upper end has a second interface 122. The lower end of the liquid storage tank 300 has a fifth interface 320, and the upper end of the gas-liquid separator 200 has a sixth interface 230 and a seventh interface 220; as Figures 1 to 4 shown, the combined module further includes: a refrigerant pipe 400, the lower end of the refrigerant pipe 400 has a third interface 410, and the upper end has a fourth interface 420; and a tee 500 (as Figure 2 shown), the tee 500 connects the first interface 121, the third interface 410, and the fifth interface 320. After the combined module is installed on the chassis, the second interface 122 of the refrigerant flow path 120 is located at the upper part, the sixth interface 230 and the seventh interface 220 of the gas-liquid separator 200 are located at the upper part, and the fourth interface 420 of the refrigerant pipe 400 is located at the upper part, all of which are convenient for connecting pipes with other components on the chassis. This solution can further improve the assembly efficiency of the outdoor unit of the air conditioner.

[0030] In some embodiments, as Figures 1 to 5 shown, the second bracket 210 is provided with a first positioning portion and a first connecting portion, and the first bracket 110 is provided with a first positioning and mating portion and a first connecting and mating portion. The first positioning portion and the first positioning and mating portion cooperate for pre-positioning, and the first connecting portion and the first connecting and mating portion cooperate for fixing.

During this process, the first connecting portion and the first connecting and mating portion are aligned, which can improve the assembly efficiency of the second bracket 210 and the first bracket 110.

During this process, the second connection portion and the second connection mating portion are aligned, which can improve the assembly efficiency of the third bracket 310 and the first bracket 110. Moreover, when the second positioning portion and the second positioning mating portion cooperate, the fifth interface 320 of the liquid storage tank 300 is inserted into the tee 500 to further pre-position the connected third bracket 310 and the liquid storage tank 300, which can better prevent the connected third bracket 310 and the liquid storage tank 300 from moving and swinging after pre-positioning.
