[0032] In an air conditioning system, a liquid storage tank is communicated with a pipeline for conveying refrigerant and is used for storing refrigerant. In some application scenarios of the air conditioner, it is necessary to reduce the volume of the air conditioning system to reduce the space occupied by the air conditioning system. For example, in an automobile, in order to save the space inside the automobile, it is necessary to miniaturize the air conditioning system. Since the liquid storage tank is an important part of the air conditioning system and the liquid storage tank has a relatively large volume, reducing the volume of the liquid storage tank plays an important role in miniaturizing the air conditioning system.

[0033] In the related art, a refrigerant inlet pipe and a refrigerant outlet pipe are provided inside the cover to communicate the inside of the liquid storage tank with the external pipeline. However, since the refrigerant inlet pipe and the refrigerant outlet pipe have a certain pipe diameter to facilitate the flow of refrigerant and the two need to be independently arranged, it is necessary to make the cover thicker to accommodate the refrigerant inlet pipe and the refrigerant outlet pipe, thereby making the cover structure complex.

[0034] Based on this, referring to Figure 1 、 Figure 2 and Figure 3 ,an embodiment of the present application provides a liquid storage tank, which includes a cylinder body 10, a cover 20 and a liquid outlet pipe 30. Wherein, the cylinder body 10 is generally a hollow cylindrical structure with one end open, the cover 20 is covered on the open end of the cylinder body 10, and together with the cylinder body 10, it defines a liquid storage cavity 10a for storing refrigerant. The liquid outlet pipe 30 is arranged in the liquid storage cavity 10a and is used for outputting the liquid refrigerant in the liquid storage cavity 10a to the external pipeline.

[0035] Specifically, the cover 20 includes a cover body 21 and a liquid outlet platform 22 provided on the cover body 21. A liquid inlet channel 22a and a liquid outlet channel 22b are formed on the liquid outlet platform 22. The liquid outlet pipe 30 is communicated between the liquid storage cavity 10a and the liquid outlet channel 22b. The liquid refrigerant enters the liquid storage cavity 10a through the liquid inlet channel 22a and can be output to the external pipeline through the liquid outlet pipe 30 via the liquid outlet channel 22b. In some specific embodiments, one end of the liquid outlet pipe 30 communicated with the liquid outlet channel 22b is arranged in the liquid outlet channel 22b. At this time, a part of the liquid outlet pipe 30 is arranged in the liquid outlet channel 22b, and the other part is arranged in the liquid storage cavity 10a. In other specific embodiments, one end of the liquid outlet pipe 30 communicated with the liquid outlet channel 22b is arranged at the opening of the liquid outlet channel 22b. At this time, the liquid outlet pipe 30 is entirely located in the liquid storage cavity 10a.

[0036] In some specific embodiments, a part of the liquid outlet platform 22 is arranged in the liquid storage cavity 10a to form a stepped portion 222, and a part of the liquid outlet channel 22b is formed in the stepped portion 222 to facilitate communication with the liquid outlet channel 22b and reduce the probability of refrigerant leakage in the liquid storage cavity. Refer to Figure 2 , specifically, the opening of the liquid outlet channel 22b communicated with the liquid storage cavity 10a is arranged on the first wall surface 22c of the liquid outlet platform 22 to facilitate the communication between the liquid outlet channel 22b and the liquid outlet pipe 30 and facilitate the installation and setting of the liquid outlet pipe 30 in the liquid storage cavity 10a. In the embodiment of the present application, by arranging the liquid outlet platform 22 on the cover body 21 of the cover 20 and concentrating the liquid inlet channel 22a and the liquid outlet channel 22b on the liquid outlet platform 22, the liquid inlet and outlet structures do not need to be arranged on the cover body 21 of the cover 20, thereby simplifying the overall structure of the cover 20 and enabling the wall thickness of the cover body 21 to be thinned, which is beneficial to the lightweight of the liquid storage tank.

[0037] In this specific embodiment, the openings of the liquid inlet channel 22a and the liquid outlet channel 22b communicated with the external pipeline are arranged on the side surface of the liquid outlet platform 22 (the side surface of the liquid outlet platform 22 refers to Figure 1 the side surface of the liquid outlet platform perpendicular to the Z direction in

[0038] ), so that the external pipeline can be directly communicated with the liquid storage tank on the side surface of the liquid storage tank, which is beneficial to reducing the space occupied by the liquid storage tank and further reducing the space occupied by the overall air-conditioning system provided with the liquid storage tank.

[0039] In some of these embodiments, the cover body 21 is hermetically sealed on the barrel body 10. Since the refrigerant stored in the liquid storage tank (where the refrigerant includes both liquid refrigerant and gaseous refrigerant) is usually volatile, hermetic connection effectively prevents the refrigerant in the liquid storage tank from leaking. In this specific embodiment, the cover 20 is welded to the barrel body 10. In this way, while meeting the requirement of hermetic connection between the two, the connection strength between the two is ensured, which is beneficial to increasing the pressure that the liquid storage tank can withstand.

[0040] Of course, in other embodiments, the cover 20 and the barrel body 10 can also be fixedly connected and sealed by means such as bonding, snap connection, and screw connection. The sealing can be achieved by providing a sealing member between the cover 20 and the barrel body 10.

[0041] In some other embodiments, the second end 32 of the liquid outlet pipe 30 is located in the liquid storage chamber 10a to facilitate sucking the liquid refrigerant in the liquid storage chamber 10a, and at the same time reduce the probability that the liquid outlet pipe 30 sucks the gaseous refrigerant in the liquid refrigerant and transports it to the external pipeline, so as to reduce the probability that the air-conditioning system is affected by the gaseous refrigerant.

[0042] Generally, when the liquid refrigerant flows into the liquid storage chamber 10a through the liquid inlet channel 22a, a turbulent flow will be formed in the liquid storage chamber 10a, and the turbulent flow will cause the liquid outlet pipe 30 to mix in gaseous refrigerant when sucking liquid, and the sucked gaseous refrigerant will be sent to the external pipeline along with the liquid refrigerant, affecting the air-conditioning system.

[0043] See Figure 3 And Figure 4 , in some embodiments, the first end 31 of the liquid outlet pipe 30 communicates with the liquid outlet channel 22b, the second end 32 of the liquid outlet pipe 30 communicates with the liquid storage chamber 10a, and is lower than the liquid inlet channel 22a in the direction of gravity ( Figure 1 And Figure 3 The Z direction in both is the same as the direction of gravity, Figure 1 In, the direction of gravity points from the cover 20 towards the barrel body 10 along the Z direction, Figure 3 In, the direction of gravity points from the first end 31 towards the second end 32 along the Z direction.). This enables a height difference to be formed between the two, so that the second end 32 can avoid the turbulent flow generated near the liquid inlet channel 22a. In this way, the possibility that the turbulent flow mixes gaseous refrigerant into the liquid outlet pipe 30 during liquid suction can be reduced, and it is avoided that the gaseous refrigerant sucked by the liquid outlet pipe 30 is transported to the external pipeline and affects the air-conditioning system.

[0044] Please refer to Figure 1 And Figure 3In some embodiments, when the cover 20 is connected to the top side of the cylinder 10 (the top side refers to the side away from the gravity direction along the Z direction). The first end 31 of the liquid outlet pipe 30 is connected to the liquid outlet channel 22b, and the second end 32 of the liquid outlet pipe 30 extends to the bottom of the liquid storage chamber 10a, that is, the second end 32 of the liquid outlet pipe 30 is maintained below the liquid inlet channel 22a in the direction of gravity (the bottom refers to the side toward the gravity direction along the Z direction) and a height difference is formed between the liquid inlet channel 22a to reduce the influence of the turbulence formed by the liquid refrigerant flowing into the liquid inlet channel 22a. In this specific embodiment, the liquid outlet pipe 30 is a pipe with a bending portion, so as to guide and buffer the liquid refrigerant during the discharge process, thereby helping to reduce the probability of turbulence, so that the liquid refrigerant flowing out of the liquid outlet pipe 30 is smooth, which can reduce the influence on the external pipeline.

[0045] In some embodiments, see Figure 1 and Figure 2 The cover 21 is recessed on one side of the liquid storage chamber 10a to form a receiving chamber 23a. The receiving chamber 23a is connected to the liquid storage chamber 10a to increase the volume of the refrigerant contained in the liquid storage tank. Figure 1 and Figure 3 In the embodiment where the sealing cover 20 is connected to the top side of the cylinder 10, the side of the cover facing the liquid storage cavity is recessed to form a receiving cavity. The receiving cavity 23a is located on the upper side of the liquid storage cavity 10a to increase the volume of the refrigerant contained in the liquid storage tank.

[0046] Please see further Figure 4 In some embodiments, when the cover 20 is coupled to the bottom side of the cylinder 10 ( Figure 4 The Z direction is in the same direction as the gravity direction, and the bottom side refers to the side of the cylinder 10 facing the gravity direction. Figure 4 When the gravity is directed in the Z direction toward the second end 32), the accommodating chamber 23a is located at the lower side of the liquid storage chamber 10a, the first end 31 of the liquid outlet pipe 30 is connected to the liquid outlet channel 22b, and the second end 32 of the liquid outlet pipe 30 is accommodated in the accommodating chamber 23a, and is maintained below the liquid inlet channel 22a in the gravity direction and forms a height difference with the liquid inlet channel 22a, so as to reduce the influence of the turbulence formed by the refrigerant flowing into the liquid inlet channel 22a on the liquid absorption by the second end 32 of the liquid outlet pipe 30. At the same time, the second end 32 of the liquid outlet pipe 30 is arranged in the accommodating chamber 23a, and the cavity wall of the accommodating chamber 23a can have a certain blocking effect on the turbulence, so as to further reduce the influence of the turbulence on the liquid absorption from the second end 32 of the liquid outlet pipe 30, thereby reducing the probability of the liquid outlet pipe 30 sucking in the gaseous refrigerant, and further reducing the influence on the air conditioning system.

[0047] That is to say, when the cover 20 is fitted to the bottom side of the cylinder 10, while the accommodation cavity 23a increases the volume of the refrigerant accommodated in the liquid storage tank, it is also used to accommodate the second end 32 of the liquid outlet pipe 30, so that a height difference is formed between the second end 32 of the liquid outlet pipe 30 and the liquid inlet channel 22a in the gravity direction, reducing the influence of the turbulent flow formed by the liquid inlet.

[0048] Please continue to refer to Figure 4 , in this specific embodiment, since the density of the gaseous refrigerant is less than that of the liquid refrigerant, when the cover 20 is fitted to the bottom side of the cylinder 10, the liquid outlet pipe 30 is configured as an inverted U-shaped pipe disposed in the liquid storage cavity 10a. At this time, both the first end 31 and the second end 32 of the liquid outlet pipe 30 are disposed on one side of the cover 20 of the liquid storage cavity 10a, and the bent portion of the inverted U-shaped pipe is higher than the first end 31 and the second end 32 of the liquid outlet pipe 30 in the gravity direction. Therefore, when the gaseous refrigerant in the liquid storage cavity 10a flows into the inverted U-shaped pipe through the second end 32, it will accumulate at the bent portion of the U-shaped pipe (that is, the inverted U-shaped pipe encloses the gaseous refrigerant at the bent portion), thereby preventing the gaseous refrigerant from flowing to the external pipeline through the first end 31 and affecting the air-conditioning system. Similarly, when the gaseous refrigerant in the external pipeline flows into the inverted U-shaped pipe through the first end 31, it will also accumulate at the bent portion of the inverted U-shaped pipe and is difficult to flow to the liquid storage cavity 10a through the second end 32, which has an adverse effect on the refrigerant in the liquid storage cavity 10a.

[0049] In some embodiments, refer to Figure 1 and Figure 2 , the cover 20 further includes a mounting portion 24 having a mounting hole 24a. The mounting portion 24 is disposed on one side of the liquid outlet platform 22 and protrudes from the outer surface of the cover body 21. When installing the liquid storage tank, an external mounting member passes through the mounting hole 24a to connect the liquid storage tank to the outside on the side, facilitating the hanging of the liquid storage tank on the outside, and thus improving the applicability of the liquid storage tank.

[0050] In this specific embodiment, there are two mounting holes 24a, and the two mounting holes 24a are spaced apart on both sides of the accommodation cavity 23a protruding from the outer surface of the cover body, so that when the mounting member is installed through the corresponding mounting hole 24a, the position where the accommodation cavity 23a is located can be avoided. It can be understood that the specific number of the mounting holes 24a is not limited, as long as the liquid storage tank is stably connected to the outside, and it is not limited here.

[0051] In some specific embodiments of the present application, refer to Figure 1, a liquid outlet platform 22 is provided with connectors 221. The connectors 221 are respectively communicated with a liquid inlet channel 22a and a liquid outlet channel 22b. An external pipeline is connected to the connectors 221. The number of the connectors 221 is two, so that the liquid inlet channel 22a and the liquid outlet channel 22b are respectively communicated with the external pipeline through the connectors 221. In this way, by providing the connectors 221, the versatility can be conveniently improved, and it is convenient for the liquid inlet channel 22a and the liquid outlet channel 22b to be communicated with the external pipeline.

[0052] Specifically, the length of the connector 221 can be adjusted, so that it is convenient to connect with the external pipeline. In addition, the connector 221 is welded to the mounting part 24, so that the connection strength between the connector 221 and the mounting part 24 is high and the probability of falling off is small.

[0053] In some embodiments, refer to Figure 3 and Figure 4 , the liquid storage tank further includes a seal 40. The seal 40 is hermetically arranged between the first end 31 of the liquid outlet pipe 30 and the communication part of the liquid outlet channel 22b to seal the gap therebetween. Specifically, the seal is a sealing ring disposed around the outside of the first end 31 to block the gap between the liquid outlet pipe 30 and the liquid outlet channel 22b in all directions, thereby reducing the probability of refrigerant leakage in the liquid storage cavity 10a.

[0054] Please refer to Figure 4 and Figure 5 , further, a sealing groove 40a for accommodating the seal 40 is formed at the position of the liquid outlet channel 22b corresponding to the seal, so as to facilitate the placement of the seal 40 and limit the seal 40 through the groove wall of the sealing groove 40a, thereby reducing the probability of the seal 40 falling off.

[0055] It can be understood that during the long-term operation of the air-conditioning system, due to reasons such as pipeline aging, the refrigerant reacts to change in properties to generate sediment substances, and external substances enter the pipeline, solid impurities will be generated in the liquid storage tank. These solid impurities will have an adverse impact on the pipeline, thereby affecting the performance of the air-conditioning system. Based on this, in some embodiments, refer to Figure 3 and Figure 4 , the liquid storage tank further includes a filter element 50. The filter element 50 is sleeved on the second end 32 of the liquid outlet pipe 30 to filter the solid impurities existing in the liquid storage cavity 10a, prevent the solid impurities from entering the external pipeline through the liquid outlet pipe 30, reduce the adverse impact of the solid impurities on the pipeline, improve the performance of the air-conditioning system and extend the service life of the air-conditioning system.

[0056] Compared with the liquid storage tank in the related art, the liquid storage tank in the embodiment of the present application has at least the following beneficial effects;

[0057] 1. In the liquid storage tank according to the embodiment of the present application, by providing a liquid outlet platform 22 on the cover 20 and concentrating the liquid inlet channel 22a and the liquid outlet channel 22b on the liquid outlet platform 22, it is not necessary to provide liquid inlet and outlet structures on the cover body 21 of the cover 20, thus simplifying the overall structure of the cover 20 and enabling the wall thickness of the cover body 21 to be thinned, which is beneficial to the lightweight of the liquid storage tank.

[0058] 2. In the liquid storage tank according to the embodiment of the present application, by making the second end 32 of the liquid outlet pipe 30 lower than the liquid inlet channel 22a along the gravity direction, a height difference can be formed between the second end 32 and the liquid inlet channel 22a, so that the second end 32 can avoid the turbulent flow. In this way, the influence of the turbulent flow on the liquid suction of the liquid outlet pipe 30 can be reduced, and further the influence on the air-conditioning system caused by the gaseous refrigerant inhaled by the liquid outlet pipe 30 being transported to the external pipeline can be reduced.

[0059] 3. In the liquid storage tank according to the embodiment of the present application, by recessing a receiving cavity 23a on the side facing the liquid storage cavity 10a and arranging the cover 20 on the bottom side of the cylinder body 10, at least part of the receiving cavity 23a is located below the liquid storage cavity 10a, and the second end 32 extends into the receiving cavity 23a. This makes a height difference formed between the second end 32 and the liquid inlet channel 22a; at the same time, the cavity wall of the receiving cavity 23a can have a certain blocking effect on the turbulent flow, so as to further reduce the influence of the turbulent flow on the liquid suction of the liquid outlet pipe 30 from the second end 32, thereby reducing the probability of the gaseous refrigerant inhaled by the liquid outlet pipe 30, and further reducing the influence on the air-conditioning system.

[0060] 4. In the liquid storage tank according to the embodiment of the present application, by providing a mounting portion 24 connected to the liquid outlet platform 22, the liquid storage tank can be externally connected through the mounting portion 24 on the side of the liquid storage tank, which is convenient for the liquid storage tank to be hung externally, thereby improving the applicability of the liquid storage tank.

[0061] It can be imagined that the liquid storage tank in the present application can also be used in other fields other than the air-conditioning system, such as the wind power generation system, the motor cooling system, etc.

[0062] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0063] The above-described embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
