[0029] 1 to 3, the present application provides a liquid reservoir 100, which is mainly used in a cooling system and is generally installed between an evaporator and a compressor of an air conditioner. When the load of the cooling system is small, the refrigerant can be returned to the liquid reservoir 100 to adjust and stabilize the amount of refrigerant circulating in the system, thereby maintaining the normal operation of the cooling system. When a part of the cooling system breaks down and needs to be overhauled, the refrigerant in the cooling system can be collected in the liquid reservoir 100 through certain operations, thereby avoiding a large amount of refrigerant being wasted due to leakage. The liquid reservoir 100 can not only store the refrigerant, but also perform gas-liquid separation on the refrigerant.

[0030] In the related art, the fixed plate of the reservoir is usually directly fitted with a welding ring on the first joint pipe, and the first joint pipe fitted with the welding ring is inserted into the fixed plate to weld the fixed plate and the first joint pipe. The welding ring is arranged horizontally when placed in the furnace, but when the brazing furnace vibrates during rotation, the welding ring is heated and softened, and slides toward a location on the fixed plate away from the welded portion, which prevents the brazing material from filling between the fixed plate and the first joint pipe, and makes it easy for abnormal noise to occur between the first joint pipe and the fixed plate.

[0031] In order to solve the problems existing in the related art with respect to welding between the fixed plate of the liquid storage container and the first connecting pipe, the present application provides a fixed plate 30 to be installed in the housing 10 of the liquid storage container 100, the liquid storage container 100 including the first connecting pipe 20, the fixed plate 30 being used to fix the first connecting pipe 20, a connection hole 31 being opened in the fixed plate 30, the connection hole 31 being used for passing through the first connecting pipe 20, a flap portion 32 being provided in the opening portion of the connection hole 31, an accommodating groove 321 for accommodating a welding ring being opened on the inner wall surface of the flap portion 32, a fixing portion 3211 being provided in the groove wall of the accommodating groove 321, and the fixing portion 3211 being used to position the welding ring.

[0032] In the present application, a fixing portion 3211 is provided in the groove wall of accommodating groove 321, and the welding ring is fixed and positioned by fixing portion 3211, thereby preventing the welding ring from being affected by the vibration of the brazing furnace or the way the welding ring is placed after it is placed in the furnace, preventing the welding ring from falling out of accommodating groove 321 and losing its effectiveness, and increasing the welding strength.

[0033] 2 and 3, after the welding ring is placed in the accommodating groove 321, in order to further increase the firmness of the welding ring in the accommodating groove 321 and prevent the welding ring from falling out of the accommodating groove 321, the outer wall of the flap portion 32 is pressed, so that the inner wall of the flap portion 32 is pressed to become the fixing portion 3211, and the fixing portion 3211 is located on the groove wall of the accommodating groove 321 close to one end of the first connecting pipe 20 and / or the fixing portion 3211 is located on the groove wall of the accommodating groove 321 away from one end of the first connecting pipe 20. That is, the fixing portion 3211 is provided on the side wall of the accommodating groove 321 close to the connecting hole 31, and / or the fixing portion 3211 is provided on the side wall of the accommodating groove 321 away from the connecting hole 31. That is, fixing portion 3211 may be provided on one side of the groove wall of accommodating groove 321, or may be configured to increase stability by pressing down the weld ring from both sides of the groove wall of accommodating groove 321. The function of fixing portion 3211 is to fix and regulate the position of the weld ring in accommodating groove 321, and when the weld ring falls off, it comes into contact with fixing portion 3211, thereby preventing the weld ring from falling off.

[0034] Here, the method of pressure processing may be several methods such as pressing, extrusion, spinning, etc., and of course, the fixing portion 3211 is not limited to being formed by the pressure processing method, but may also be formed by a method of applying drawing to the groove wall of the accommodating groove 321, and the drawing method may be diameter reduction drawing or diameter expansion drawing, etc., and the processing method of the fixing portion 3211 is not specifically limited here.

[0035] In one embodiment, the fixing portion 3211 includes a protrusion 3211a, and the protrusion 3211a is annular and provided along the circumferential direction of the groove wall of the accommodating groove 321. In other words, the fixing portion 3211 may be an annular convex muscle provided around the entire circumference of the groove wall of the accommodating groove 321, which can prevent the weld ring from falling off in each direction.

[0036] In one embodiment, the fixing portion 3211 includes a plurality of protrusions 3211a, and the protrusions 3211a are spaced apart along the circumferential direction of the groove wall of the accommodating groove 321. That is, the fixing portion 3211 may be a plurality of bumps distributed at intervals on the groove wall of the accommodating groove 321.

[0037] In this embodiment, the shape, installation form, and installation position of the fixing portion 3211 are variously possible, and are not limited here as long as they can realize the prevention of the weld ring in the receiving groove 321.

[0038] Furthermore, the fixing portion 3211 includes a step 3211b. The step 3211b is located in the accommodation groove 321 and is formed by narrowing one end of the flap portion 32. The fixing portion 3211 may also be formed by narrowing the outer wall of the flap portion 32, clamping the welding ring in the accommodation groove 321, and tightening it in the accommodation groove 321, which further increases the firmness of the welding ring in the accommodation groove 321. As a result, when the first joint pipe 20 is extended into the flap portion 32 and welded through the connection hole 31 of the fixing plate 30, the welding ring will not fall off, and the welding strength between the first joint pipe 20 and the fixing plate 30 is ensured.

[0039] Furthermore, the fixed plate 30 is provided with a plurality of filter holes 33, which are evenly distributed along the circumferential direction of the fixed plate 30. The filter holes 33 are used to pass the gas-liquid mixed refrigerant when it flows onto the fixed plate 30, and allow the liquid phase refrigerant to flow through the filter holes 33 to the bottom of the housing 10.

[0040] It should be noted that the receiving groove 321 is not limited to receiving a weld ring, but may also receive other materials such as solder, and is not limited thereto.

[0041] The present application further provides a liquid reservoir 100 including a housing 10, a first connecting pipe 20, and a fixing plate 30. A sealed receiving chamber 11 is formed in the housing 10, and the fixing plate 30 is attached to the receiving chamber 11. One end of the first connecting pipe 20 is located in the receiving chamber 11, and the other end extends outside the housing 10.

[0042] As shown in FIG. 1, the housing 10 is generally cylindrical with narrowed ends, but of course in other embodiments the housing 10 may have other shapes, such as a rectangular prism, and this is not limited here.

[0043] Furthermore, a first flow port 12 is opened at one end of the housing 10, and a second flow port 13 and a third flow port 14 are opened at a distance from each other at the other end. The first flow port 12, the second flow port 13, and the third flow port 14 all communicate with the storage chamber 11. The refrigerant flows into the storage chamber 11 through the first flow port 12, and then flows out of the storage chamber 11 through the second flow port 13 and the third flow port 14.

[0044] Specifically, the second connecting pipe 21 is inserted into the housing 10 through the first flow port 12 and is welded and fixed to the housing 10, and one end of the second connecting pipe 21 extends into the housing 10 and the other end extends outward from the housing 10 to connect to other pipelines within the air conditioning system, and is used to introduce the refrigerant from the other pipelines into the storage chamber 11 through the second connecting pipe 21. The first extension pipe 20 includes a first connecting pipe 201 and a second connecting pipe 202, which are inserted into the housing 10 via the second flow port 13 and the third flow port 14, respectively, and are fixed by welding to the housing 10. The first connecting pipe 201 and the second connecting pipe 202 have one end extending into the housing 10 and the other end extending outward from the housing 10 to connect to other pipes in the air conditioning system, and are used to discharge the refrigerant in the storage chamber 11 via the first connecting pipe 201 and the second connecting pipe 202. In other embodiments, the first extension pipe 20 may be provided as a plurality of connecting pipes as necessary.

[0045] The first and second joint pipes 20 and 21 are both welded to the housing 10, which improves the overall connection seal and reliability. The outer surface of the housing 10 is coated with a special powder coating, which has passed a rigorous neutral salt spray test and has good corrosion resistance.

[0046] In this embodiment, the first connecting pipe 20 and the second connecting pipe 21 can both be made of copper to facilitate the user to weld them to other pipes in the air conditioning system; however, of course, in other embodiments, the first connecting pipe 20 and the second connecting pipe 21 can be made of other materials, such as stainless steel, which are not limited here.

[0047] Furthermore, the fixed plate 30 is fixedly connected to the inner wall of the housing 10, and one end of the first connecting pipe 20 adjacent to the second connecting pipe 21 extends into the connecting hole 31 and is welded to the fixed plate 30, thereby realizing the fixing of the first connecting pipe 20 in the housing 10. Optionally, the fixed plate 30 can be provided integrally with or separately from the housing 10, and is not limited here.

[0048] Furthermore, the first extension pipe 20 includes a straight pipe portion 203 extending into the housing 10 and a curved pipe portion 204 outside the housing 10, and the straight pipe portion 203 is fixedly connected to the curved pipe portion 204 or is provided integrally with the straight pipe portion 203.

[0049] The fixing plate 30 provided by the present application has fixing parts 3211 provided on the groove walls of the accommodating groove 321, so that the fixing parts 3211 fix the weld ring and regulate its position, preventing the weld ring from being affected by the vibrations of the brazing furnace or the way the weld ring is placed after it is inserted into the furnace. This prevents the weld ring from falling out of the accommodating groove 321 and losing its effectiveness, and increases the weld strength.

[0050] The present application further provides an air conditioning system 200 including the reservoir 100, as shown in FIG.

[0051] The technical features of the above-mentioned examples may be combined in any combination. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
