[0003] During the operation of the compressor, vibrations will be generated. The existing liquid receiver is rigidly connected to the compressor and the return air pipe. The vibrations generated by the compressor easily cause fatigue fracture of the air conditioner return air pipe, and noise will be generated during the vibration process. Summary of the Invention

[0008] A first suction pipe, inserted into the first connecting pipe and hermetically connected to the first connecting pipe, and a first elastic sealing ring is provided between the first suction pipe and the first connecting pipe.

[0009] Optionally, the first suction pipe is welded to the end of the first connecting pipe away from the tank body.

[0010] Optionally, the first suction pipe has a first pipe portion extending out of the first connecting pipe and a second pipe portion received in the first connecting pipe, and the length of the second pipe portion is greater than the length of the first pipe portion.

[0013] Optionally, the first installation groove is formed by roll forming.

[0014] Optionally, the first suction pipe is an aluminum pipe or a copper pipe.

[0015] Optionally, the liquid reservoir further includes:

[0016] A second connecting pipe connected to and communicating with the interior of the tank at an end of the tank facing away from the first connecting pipe; and

[0017] A second suction pipe inserted into the second connecting pipe and sealingly connected to the second connecting pipe, with a second elastic sealing ring provided between the second suction pipe and the second connecting pipe.

[0018] Optionally, the second connecting pipe is disposed inside the tank, and the first suction pipe is welded to an end of the second connecting pipe away from the tank.

[0019] Optionally, the number of the second elastic sealing rings is multiple, and the second elastic sealing rings are arranged at intervals along the axial direction of the second suction pipe.

[0020] Optionally, the second suction pipe and / or the second connecting pipe are / is provided with a second mounting groove for cooperating with the second elastic sealing ring.

[0028] For the liquid storage device of the technical solution of the present invention, the first connecting pipe is connected to one end of the tank body. By inserting the first suction pipe into the first connecting pipe and sealingly connecting it to the first connecting pipe, the first suction pipe is not directly connected to the tank body. In this way, during the operation of the compressor, the vibration generated needs to pass through the tank body and the first connecting pipe in sequence before being transmitted to the first suction pipe. The vibration energy gradually attenuates during the transmission process, thereby reducing the vibration transmitted from the compressor to the first suction pipe. Additionally, by providing a first elastic sealing ring between the first connecting pipe and the first suction pipe, the first elastic sealing ring can absorb the vibration energy transmitted by the first connecting pipe. In this way, the vibration transmitted from the first connecting pipe to the first suction pipe is further weakened, thereby significantly reducing the vibration transmitted from the first suction pipe to the return air pipe of the heat exchange device, and further reducing the risk of fatigue fracture of the return air pipe due to long-term vibration, extending the service life of the return air pipe, and reducing the noise generated by the vibration at the same time.

When the combination of technical solutions conflicts with each other or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0040] The present invention provides a liquid reservoir.

[0041] Among them, the liquid reservoir is used in the compressor assembly of a heat exchange device. It is arranged at the end of the refrigeration circuit. Since the refrigerant exists in both liquid and gaseous states when it returns to the compressor, the liquid reservoir is used to separate the liquid and gas of the refrigeration medium flowing out of the circuit pipeline, prevent the refrigerant liquid from entering the compressor, and prevent the compressor from being damaged by liquid hammer. The liquid reservoir will be described in detail below.

[0042] Refer to Figures 1 to 4 , in the embodiment of the present invention, the liquid reservoir 100 includes a tank body 110, a first connecting pipe 120, and a first suction pipe 130; as Figure 1 shown, the first connecting pipe 120 is connected to one end of the tank body 110 and is in communication with the inside of the tank body 110; the first suction pipe 130 is inserted into the first connecting pipe 120 and is hermetically connected to the first connecting pipe 120, and a first elastic sealing ring 140 is provided between the first suction pipe 130 and the first connecting pipe 120.

[0043] One end of the tank body 110 is communicated with the return air pipeline of the heat exchange device, and the other end of the tank body 110 is communicated with the compressor. A filter sheet 111 is arranged inside the tank body 110. The filter sheet 111 divides the inside of the tank body 110 into an upper cavity 112 and a lower cavity 113. The filter sheet 111 is used for gas-liquid separation of the refrigeration medium (including gas and liquid) flowing into the upper cavity 112 from the return air pipeline of the heat exchange device. As Figure 1 shown, the filter sheet 111 is welded to the inner side wall of the tank body 110. A blocking portion bulges in the middle of the filter sheet 111, and filter holes are formed around the blocking portion. The filter holes communicate the upper cavity 112 and the lower cavity 113. When the refrigeration medium in the return air pipeline enters the upper cavity 112, under the blocking of the blocking portion, the liquid falls into the lower cavity 113 through the filter holes and is stored at the bottom of the tank body 110, while the separated gas enters the compressor through the pipeline.

[0044] Referring to Figure 1 , the first connecting pipe 120 is welded to the upper end of the tank body 110 and communicated with the upper cavity 112. In order to ensure the sealing performance of the tank body 110, the first connecting pipe 120 and the tank body 110 are welded on both sides. Due to the limitation of the space of the upper cavity 112, most of the first connecting pipe 120 is arranged outside the tank body 110. The first suction pipe 130 is inserted into the first connecting pipe 120 and is hermetically connected to the first connecting pipe 120. The first suction pipe 130 is used for connecting with the return air pipeline of the heat exchange device, so that the refrigeration medium in the return air pipeline of the heat exchange device enters the upper cavity 112 through the first suction pipe 130.

[0045] It can be understood that when the compressor works, the vibration generated by the compressor is transmitted to the tank body 110 through the pipeline, causing the tank body 110 to vibrate accordingly. The vibration generated by the tank body 110 is transmitted from bottom to top. In this embodiment, by connecting the first connecting pipe 120 with the tank body 110, and the first suction pipe 130 is inserted into the first connecting pipe 120 and hermetically connected to the connecting pipe. In this way, the first suction pipe 130 is not directly connected to the tank body 110. The vibration generated by the compressor has to pass through the tank body 110 and the first connecting pipe 120 in sequence to be transmitted to the first suction pipe 130, and the vibration energy gradually decays during the transmission process, so that the vibration transmitted from the compressor to the first suction pipe 130 can be reduced, and further the vibration received by the return air pipe of the heat exchange device can be reduced.

[0046] Among them, the first suction pipe 130 and the first connecting pipe 120 can be hermetically sealed by welding, adhesive connection, threaded connection or ferrule connection. In this embodiment, in order to ensure the sealing performance and the connection stability, and at the same time to simplify the sealing structure, the first suction pipe 130 and the first connecting pipe 120 are preferably hermetically connected by welding.

[0047] In order to further weaken the vibration, a first elastic sealing ring 140 is also arranged between the first suction pipe 130 and the first connecting pipe 120. As Figure 1 andFigure 2 As shown in the figure. Among them, the material of the first elastic sealing ring 140 is a rubber material. It can be understood that rubber is an elastic material, which can absorb vibration, and rubber has a high density and is easy to absorb noise. By arranging the first elastic sealing ring 140 between the first connecting pipe 120 and the first suction pipe 130, and the first elastic sealing ring 140 has good elasticity, it can absorb the vibration energy transmitted by the first connecting pipe 120, reduce the vibration energy, so that the vibration transmitted from the first connecting pipe 120 to the first suction pipe 130 is weakened. Furthermore, the vibration transmitted from the first suction pipe 130 to the return air pipe of the heat exchange device is greatly weakened, thereby reducing the risk of fatigue fracture of the return air pipe due to vibration and extending the service life of the return air pipe; at the same time, the first elastic sealing ring 140 absorbs noise, thereby reducing the noise generated by vibration.

[0048] Of course, in other embodiments, it is not limited to using the first elastic sealing ring 140 to absorb the vibration energy transmitted by the first connecting pipe 120. Elastic components such as silicone balls and scroll springs with elasticity or elastic force can also be used as replacements for the first elastic sealing ring 140.

[0049] It can be understood that the outer diameter of the first suction pipe 130 should be less than or equal to the inner diameter of the first connecting pipe 120, so that the first suction pipe 130 can be smoothly inserted into the first connecting pipe 120. In this embodiment, in order to reduce the contact area between the first suction pipe 130 and the first connecting pipe 120 to reduce vibration transmission, and at the same time to leave an installation gap for installing the first elastic sealing ring 140, this embodiment preferably sets the outer diameter of the first suction pipe 130 to be less than the inner diameter of the first connecting pipe 120.

[0050] For the liquid storage device 100 of the technical solution of the present invention, the first connecting pipe 120 is connected to one end of the tank body 110. By inserting the first suction pipe 130 into the first connecting pipe 120 and sealingly connecting it with the first connecting pipe 120, the first suction pipe 130 is not directly connected to the tank body 110. In this way, the vibration generated during the operation of the compressor has to pass through the tank body 110 and the first connecting pipe 120 in sequence before being transmitted to the first suction pipe 130, and the vibration energy gradually attenuates during the transmission process, thereby reducing the vibration transmitted from the compressor to the first suction pipe 130; also, by arranging the first elastic sealing ring 140 between the first connecting pipe 120 and the first suction pipe 130, the first elastic sealing ring 140 can absorb the vibration energy transmitted by the first connecting pipe 120. In this way, the vibration transmitted from the first connecting pipe 120 to the first suction pipe 130 is further weakened, thereby greatly reducing the vibration transmitted from the first suction pipe 130 to the return air pipe of the heat exchange device, and further reducing the risk of fatigue fracture of the return air pipe due to long-term vibration, extending the service life of the return air pipe, and at the same time reducing the noise generated by vibration.

[0051] Furthermore, in one embodiment, referring toFigure 1 The first suction pipe 130 is welded to one end of the first connecting pipe 120 away from the tank body 110. It can be understood that since the vibration generated by the compressor is transmitted from the lower end of the tank body 110 towards the upper end of the tank body 110, during the transmission of the vibration, the vibration energy gradually decreases. By welding the first suction pipe 130 to one end of the first connecting pipe 120 away from the tank body 110, the transmission path of the vibration can be increased, so that the vibration transmitted to the first suction pipe 130 is further weakened.

[0052] Furthermore, referring to Figure 1 and Figure 2 the first suction pipe 130 has a first pipe portion 131 extending out of the first connecting pipe 120 and a second pipe portion 132 received in the first connecting pipe 120, and the length of the second pipe portion 132 is greater than the length of the first pipe portion 131. Among them, the first pipe portion 131 is used to connect with the return air pipe of the heat exchange device, and the second pipe portion 132 is a free end.

[0053] It can be understood that since the length of the second pipe portion 132 is greater than the length of the first pipe portion 131, the rigidity of the second pipe portion 132 is relatively low, and the second pipe portion 132 is a free end. Thus, the second pipe portion 132 is more vulnerable to vibration than the first pipe portion 131. When the vibration is transmitted to the first connecting pipe 120, the first elastic sealing ring 140 first transmits the vibration to the second pipe portion 132 and makes the vibration concentrate on the second pipe portion 132, while the vibration transmitted to the first pipe portion 131 is weakened, thereby further reducing the vibration transmitted from the first suction pipe 130 to the return air pipe of the heat exchange device.

[0054] Furthermore, in an embodiment, in order to further enhance the vibration absorption effect, the number of the first elastic sealing rings 140 is multiple, and the first elastic sealing rings 140 are arranged at intervals along the axial direction of the first suction pipe 130. As Figure 2 shown, by arranging multiple first elastic sealing rings 140 in the axial direction of the first suction pipe 130, the vibration energy transmitted by the first connecting pipe 120 is absorbed by the multiple first elastic sealing rings 140 from bottom to top, so that the vibration transmitted to the first suction pipe 130 is greatly attenuated.

[0055] Further, the first air suction pipe 130 and / or the first connecting pipe 120 are provided with a first installation groove 150 that cooperates with the first elastic sealing ring 140. It can be understood that by providing the first installation groove 150 that cooperates with the first elastic sealing ring 140 between the first air suction pipe 130 and the first connecting pipe 120, on the one hand, it is convenient to insert the whole of the first air suction pipe 130 and the first elastic sealing ring 140 into the first connecting pipe 120, so that the first elastic sealing ring 140 is in the set position of the first installation groove 150; on the other hand, the first installation groove 150 has a positioning effect on the first elastic sealing ring 140, which can prevent the first elastic sealing ring 140 from displacing under long-term vibration and falling from the installation gap between the first air suction pipe 130 and the first connecting pipe 120.

[0056] Wherein, when the first installation groove 150 is provided on the first air suction pipe 130, as Figure 2 shown, the first installation groove 150 is recessed towards the inside of the first air suction pipe 130; when the first installation groove 150 is provided on the first connecting pipe 120, the first installation groove 150 protrudes towards the outside of the first connecting pipe 120; when the first installation groove 150 is provided on both the first air suction pipe 130 and the first connecting pipe 120 at the same time, the two first installation grooves 150 are arranged oppositely.

[0057] Wherein, the number of the first installation grooves 150 corresponds to the number of the first elastic sealing rings 140. When the number of the first installation grooves 150 is multiple, the interval distances between the multiple first installation grooves 150 can be the same, can be set in an arithmetic progression, can also be set in a geometric progression. Of course, the interval distances between the multiple first installation grooves 150 can also be set randomly without a pattern. The setting of the interval distances between the multiple first installation grooves 150 is not limited here. In this embodiment, the interval distances between the first installation grooves 150 are taken as an example of being the same, as Figure 2 shown.

[0058] Further, in order to enhance the overall strength of the first connecting pipe 120 and / or the first air intake pipe 130, the first installation groove 150 is formed by roll forming. It can be understood that, compared with cutting the first installation groove 150 on the outer wall of the first air intake pipe 130 or the inner wall of the first connecting pipe 120 by mechanical cutting, the first installation groove 150 is formed by roll forming in this embodiment, so that the connection between the first installation groove 150 and the first air intake pipe 130 or the first connecting pipe 120 is an arc transition, and there is no cutting stress at the arc transition, which is not easy to crack in a long-term vibration environment, thereby extending the service life of the first air intake pipe 130 and / or the first connecting pipe 120; in addition, the cross-sectional shape of the first installation groove 150 formed by roll forming is semicircular or semi-elliptical, which can contact with the first elastic sealing ring 140 more fully, increasing the contact area between the first elastic sealing ring 140 and the first connecting pipe 120 or the first air intake pipe 130, so that the first elastic sealing ring 140 can fully absorb vibration. In this way, the first mounting groove 150 can enhance the strength of the first connecting pipe 120 or the first intake pipe 130 and extend its service life through rolling and roller forming. At the same time, it can enhance the vibration absorption effect of the first elastic sealing ring 140 and further weaken the vibration transmitted from the first connecting pipe 120 to the first intake pipe 130.

[0059] Furthermore, in this embodiment, the first air intake pipe 130 is an aluminum tube or a copper tube. It can be understood that, compared with the stainless steel tube or carbon steel tube used in the prior art, the aluminum tube or the copper tube has lower rigidity and is easier to absorb the vibration transmitted by the first connecting pipe 120, and the aluminum tube or the copper tube is not easy to rust.

[0060] It can be understood that the first connecting pipe 120 and the tank body 110 are made of the same material, so that the first connecting pipe 120 and the tank body 110 have better welding fusion, more stable connection, and better sealing.

[0061] The present invention also proposes another embodiment, referring to Figure 3 and Figure 4 The liquid storage tank 100 also includes a second connecting pipe 160 and a second air intake pipe 170. The second connecting pipe 160 is connected to one end of the tank body 110 away from the first connecting pipe 120 and is connected to the interior of the tank body 110. The second air intake pipe 170 is inserted into the second connecting pipe 160 and is sealed with the second connecting pipe 160. A second elastic sealing ring 180 is provided between the second air intake pipe 170 and the second connecting pipe 160.

[0062] like Figure 3As shown, the second connecting pipe 160 is welded to the lower end of the tank body 110 and communicates with the lower cavity 113 of the tank body 110. The second suction pipe 170 is inserted into the second connecting pipe 160 and is hermetically connected to the second connecting pipe 160. The second suction pipe 170 is used to connect to a compressor so that the gaseous refrigeration medium in the lower cavity 113 enters the compressor through the second suction pipe 170 for refrigeration cycle.

[0063] Understandably, by connecting the second connecting pipe 160 to the tank body 110 and inserting the second suction pipe 170 into the second connecting pipe 160 and hermetically connecting them, in this way, the second connecting pipe 160 is not directly connected to the compressor. When the compressor is working, the vibration generated by the compressor has to pass through the second suction pipe 170 and the second connecting pipe 160 in sequence to be transmitted to the tank body 110, so that the vibration energy decays during the transmission process, thereby weakening the vibration transmitted from the compressor to the tank body 110, and further weakening the vibration transmitted from the tank body 110 to the first suction pipe 130.

[0064] Among them, similarly to the above, the second suction pipe 170 and the second connecting pipe 160 can be hermetically sealed by welding, adhesive connection, threaded connection or ferrule connection. In this embodiment, in order to ensure the sealing performance and the stability of the connection, and at the same time to simplify the sealing structure, the second suction pipe 170 and the second connecting pipe 160 are preferably hermetically connected by welding.

[0065] To further weaken the vibration, a second elastic sealing ring 180 is provided between the second suction pipe 170 and the second connecting pipe 160, as Figure 3 shown. The material of the second elastic sealing ring 180 is also rubber material. Understandably, by providing the second elastic sealing ring 180 between the second suction pipe 170 and the second connecting pipe 160, the second elastic sealing ring 180 has good elasticity and can absorb the vibration energy transmitted by the second suction pipe 170, reducing the vibration energy. In this way, the vibration transmitted from the second suction pipe 170 to the second connecting pipe 160 is weakened, and further the vibration transmitted from the second connecting pipe 160 to the tank body 110 is weakened.

[0066] In this way, in the entire vibration transmission path, the vibration generated by the compressor has to pass through the second suction pipe 170, the second elastic sealing ring 180, the second connecting pipe 160, the tank body 110, the first connecting pipe 120, the first elastic sealing ring 140, and the first suction pipe 130 in sequence to be transmitted to the return air pipe of the heat exchange device, greatly extending the vibration transmission path, and the second elastic sealing ring 180 and the first elastic sealing ring 140 absorb the vibration energy at the upper and lower ends of the tank body 110 successively, so that the vibration finally transmitted from the compressor to the return air pipe is greatly weakened, thereby reducing the risk of fatigue fracture of the return air pipe due to long-term vibration, and further extending the service life of the return air pipe.

[0067] Wherein, the inner diameter of the second connecting pipe 160 is greater than or equal to the outer diameter of the second suction pipe 170, so that the second suction pipe 170 can be smoothly inserted into the second connecting pipe 160. In this embodiment, in order to prevent the second suction pipe 170 from directly contacting the second connecting pipe 160 to reduce vibration transmission, and at the same time to leave an installation gap for installing the second elastic sealing ring 180, this embodiment preferably sets the inner diameter of the second connecting pipe 160 to be greater than the outer diameter of the second suction pipe 170.

[0068] Furthermore, in an embodiment, in order to reduce the overall height of the liquid storage tank 100, the second connecting pipe 160 is arranged inside the tank body 110, and the first suction pipe 130 is welded to the end of the second connecting pipe 160 far away from the tank body 110. It can be understood that since the vibration generated by the compressor is transmitted to the tank body 110 through the second suction pipe 170 and the second connecting pipe 160 in sequence, by welding the second suction pipe 170 and the end of the second connecting pipe 160 far away from the tank body 110, the vibration transmission path can be increased, so that the vibration transmitted to the tank body 110 is further weakened.

[0069] Wherein, for the convenience of welding the second suction pipe 170 to the compressor and the second connecting pipe 160, the second suction pipe 170 is divided into a straight pipe section 171 and a bent pipe section 172 connected to the straight pipe section 171. Among them, the straight pipe section 171 is welded to the second connecting pipe 160, and the bent pipe section 172 is connected to the compressor. Refer to Figure 3 and Figure 4 , the straight pipe section 171 includes a third pipe portion 1711 extending out of the second connecting pipe 160 and a fourth pipe portion 1712 received in the second connecting pipe 160. The fourth pipe portion 1712 is connected to the end of the bent pipe section 172 far away from the compressor (it can be welded, adhesively connected or threadedly connected). The third pipe portion 1711 is a free end. In order to prevent the liquid refrigerant in the tank body 110 from storing too much and flowing in from the third pipe portion 1711, the third pipe portion 1711 extends deep into the tank body 110 near the filter element 111.

[0070] Furthermore, in an embodiment, in order to further enhance the vibration absorption effect, the number of the second elastic sealing rings 180 is multiple, and the second elastic sealing rings 180 are arranged at intervals along the axial direction of the second suction pipe 170. As Figure 4 shown, by arranging multiple second elastic sealing rings 180 in the axial direction of the second suction pipe 170, the vibration energy transmitted by the second suction pipe 170 is absorbed by the multiple second elastic sealing rings 180 from bottom to top, so that the vibration transmitted to the second connecting pipe 160 is greatly attenuated, thereby reducing the vibration transmitted from the second connecting pipe 160 to the tank body 110.

[0071] Furthermore, in one embodiment, the second air suction pipe 170 and / or the second connecting pipe 160 are provided with a second installation groove 190 that cooperates with the second elastic sealing ring 180. It can be understood that by providing a second installation groove 190 that cooperates with the second elastic sealing ring 180 between the second air suction pipe 170 and the second connecting pipe 160, on the one hand, it is convenient to insert the whole of the second air suction pipe 170 and the second elastic sealing ring 180 into the second connecting pipe 160, so that the second elastic sealing ring 180 is in the set position of the second installation groove 190; on the other hand, the second installation groove 190 has a positioning effect on the second elastic sealing ring 180, which can prevent the second elastic sealing ring 180 from falling off from the installation gap between the second air suction pipe 170 and the second connecting pipe 160 due to displacement caused by long-term vibration.

[0072] Among them, when the second installation groove 190 is provided on the second air suction pipe 170, as Figure 4 shown, the second installation groove 190 is recessed toward the inside of the second air suction pipe 170; when the second installation groove 190 is provided on the second connecting pipe 160, the second installation groove 190 protrudes toward the outside of the second connecting pipe 160; when the second installation groove 190 is provided on both the second air suction pipe 170 and the second connecting pipe 160 at the same time, the two second installation grooves 190 are arranged oppositely.

[0073] Among them, the number of the second installation grooves 190 corresponds to the number of the second elastic sealing rings 180. When the number of the second installation grooves 190 is multiple, the interval distances between the multiple second installation grooves 190 can be the same, can be set in an arithmetic progression, can also be set in a geometric progression. Of course, the interval distances between the multiple second installation grooves 190 can also be set randomly without a rule. The setting of the interval distances between the multiple second installation grooves 190 is not limited here. In this embodiment, the interval distances between the second installation grooves 190 are taken as an example of being the same, as Figure 4 shown.

[0074] Furthermore, in order to further enhance the overall strength of the second connecting pipe 160 and / or the second suction pipe 170, the second installation groove 190 is formed by roll forming. It can be understood that, similarly to the above, compared with cutting the second installation groove 190 on the outer wall of the second suction pipe 170 or the inner wall of the second connecting pipe 160 by mechanical cutting, in this embodiment, the second installation groove 190 is formed by roll forming. Thus, the connection between the second installation groove 190 and the second suction pipe 170 or the second connecting pipe 160 has a circular arc transition, which can improve the overall strength of the second connecting pipe 160 or the second suction pipe 170, and there is no cutting stress at the circular arc transition, so it is not easy to crack in a long-term vibrating environment, thereby extending the service life of the second suction pipe 170 and / or the second connecting pipe 160; in addition, for the second installation groove 190 formed by roll forming, its cross-sectional shape is semi-circular or semi-elliptical, which can be in fuller contact with the second elastic sealing ring 180, increasing the contact area between the second elastic sealing ring 180 and the second connecting pipe 160 or the second suction pipe 170, so that the second elastic sealing ring 180 can fully absorb vibrations. Thus, the second installation groove 190 is formed by roll forming, which can enhance the strength of the second connecting pipe 160 or the second suction pipe 170, extend its service life, and at the same time, can enhance the vibration absorption effect of the second elastic sealing ring 180, further weakening the vibration transmitted from the second suction pipe 170 to the second connecting pipe 160.

[0075] The present invention also provides a compressor assembly, which includes a compressor and a liquid receiver 100. The specific structure of the liquid receiver 100 refers to the above embodiments. Since this compressor assembly adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one. Among them, the liquid receiver 100 is connected to the compressor. Specifically, the second suction pipe 170 of the liquid receiver 100 is connected to the compressor.

[0076] The present invention also provides a heat exchange device, which includes a main unit and a compressor assembly. Among them, the main unit has heat exchange pipes, and the heat exchange pipes include loop pipes. The first suction pipe 130 of the liquid receiver 100 of the compressor assembly is connected to the loop pipes, so that the refrigerant flowing out of the return air pipe enters the tank body 110 of the liquid receiver 100 through the first suction pipe 130 and flows into the compressor through the second suction pipe 170, thereby participating in the refrigeration cycle. Specifically, the heat exchange device can be an air conditioner, a refrigerator, etc.

[0077] The above are only the optional embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural transformations made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
