With reference to these contents, those skilled in the art should be able to understand other possible implementations and the advantages of the utility model.

[0029] In the related art, according to the classification of the installation direction, the compressor types can be divided into vertical types and horizontal types, wherein the horizontal type compressor uses a horizontal direction of horizontal installation for the liquid accumulator. The structure of the liquid storage tank body used in the existing horizontal liquid accumulator is generally in the shape of a cylindrical barrel, and with the miniaturization of the refrigeration system, the requirements for liquid impact resistance and noise of the compressor are also increasing. In the miniaturization design, the liquid storage tank body on the low pressure side has a large noise problem due to the cylindrical design.

[0030] In view of this, the utility model embodiment provides a horizontal liquid accumulator and a horizontal compressor. According to the horizontal liquid accumulator and the horizontal compressor of the utility model embodiment, the necked portion 11 is designed on the horizontal liquid accumulator to achieve the effect of reducing noise and reducing the risk of liquid droplets entering the compressor pump body with high pressure gas flow.

[0031] Please refer to Figures 1 to 4 The utility model embodiment provides a horizontal liquid accumulator, which comprises:

[0032] The liquid storage tank body 10 is a cylindrical structure with one end open, the open end of the liquid storage tank body 10 is connected with the pipe fitting connector 20, the outer peripheral wall of the liquid storage tank body 10 is inwardly recessed to form a necked portion 11, the necked portion 11 divides the inside of the liquid storage tank body 10 into the sound attenuation cavity 12 and the exhaust cavity 13 which are in communication with each other, one end of the sound attenuation cavity 12 is in communication with the pipe fitting connector 20, the inner diameter of the necked portion 11 is d, the inner diameter of the liquid storage tank body 10 is D, and 1.2≤D / d≤4;

[0033] The exhaust pipe 30 is inserted into the exhaust cavity 13 from the bottom of the outer peripheral wall of the liquid storage tank body 10 in a direction perpendicular to the axis of the liquid storage tank body 10.

[0034] Therefore, according to the horizontal liquid storage device in the embodiment of the present application, the necked portion 11 is formed by inwardly recessing the outer peripheral wall of the liquid storage tank body 10, so that the liquid storage tank body 10 is divided into the sound attenuation cavity 12 and the exhaust cavity 13 which are in communication with the pipe fitting connector 20 through the necked portion 11. In this way, the necked portion 11 is designed to be inwardly recessed, so that the side of the sound attenuation cavity 12 which is in communication with the necked portion 11 is designed to be necked. The reflection direction of the sound waves generated by the high-pressure gas flow entering the sound attenuation cavity 12 from the pipe fitting connector 20 is changed, part of the sound waves produces reverse resonance and cancels each other out, which can effectively improve the noise problem caused by the sound waves generated by the high-pressure gas flow, and make the working environment of the horizontal liquid storage device more quiet. In addition, part of the liquid-phase refrigerant in the high-pressure gas flow will also impact on the necked inner wall of the sound attenuation cavity 12, thereby increasing the impact area of the liquid-phase refrigerant and effectively promoting the sedimentation effect of the liquid-phase refrigerant, which can effectively reduce the risk of the liquid-phase refrigerant entering the compressor pump body with the high-pressure gas flow.

[0035] Further, in the embodiment of the present application, the length of the sound attenuation cavity 12 in the axial direction of the liquid storage tank body 10 is L1, the length of the exhaust cavity 13 in the axial direction of the liquid storage tank body 10 is L2, and 1 / 5≤L1 / L2≤1 / 3. It can be understood that, in the embodiment of the present application, the necked portion 11 divides the liquid storage tank body 10 into two cylindrical structures with different lengths, and by designing the length ratio of the sound attenuation cavity 12 to the exhaust cavity 13 as 1 / 5≤L1 / L2≤1 / 3, both the effect of reducing noise through the sound attenuation cavity 12 and the effect of ensuring that the length of the exhaust cavity 13 is sufficient for the liquid-phase refrigerant to settle can be achieved, so that the noise reduction effect and the effect of reducing liquid backflow to the compressor of the horizontal liquid storage device in the embodiment of the present application are better.

[0036] Optionally, in some embodiments of the present application, the wall thickness of the liquid storage tank 10 is t, the distance from the one end of the exhaust pipe 30 extending into the liquid storage tank 10 to the inner wall of the liquid storage tank 10 along the extending direction of the one end is h, and h≤(D-d) / 2+t. It can be understood that in these embodiments, by limiting the distance h between the one end of the exhaust pipe 30 extending into the liquid storage tank 10 and the inner top of the liquid storage tank 10 to h≤(D-d) / 2+t, the extending length of the one end of the exhaust pipe 30 extending into the liquid storage tank 10 can be longer, so that the liquid-phase refrigerant in the gas can be more completely settled before entering the exhaust pipe 30, which can effectively reduce the risk of the liquid-phase refrigerant entering the compressor pump body with the high-pressure gas flow.

[0037] Optionally, in some embodiments of the present application, the cross-sectional profile of the necked portion 11 along the axial direction of the liquid storage tank 10 is two arc-shaped profiles which are symmetrical to the axis of the liquid storage tank 10. It can be understood that in these embodiments, the cross-sectional profile of the necked portion 11 is an arc-shaped concave structure. However, it can be understood that the cross-sectional profile of the necked portion 11 of the present application is not limited to the arc-shaped concave structure in these embodiments, but can also be a reverse trapezoidal concave structure, etc., which will not be described here.

[0038] Optionally, in some embodiments of the present application, the minimum inner diameter d of the necked portion 11 satisfies the relationship: d≥5cm. It can be understood that in these embodiments, by limiting the minimum inner diameter d of the necked portion 11 to d≥5cm, the problem of unsmooth gas flow caused by too narrow necked portion 11 can be avoided.

[0039] Optionally, in some embodiments of this utility model, a liquid-blocking filter plate 40 is coaxially arranged in the exhaust chamber 13. The outer peripheral wall of the liquid-blocking filter plate 40 is connected to the inner peripheral wall of the exhaust chamber 13, and the liquid-blocking filter plate 40 is located between the constriction portion 11 and the exhaust pipe 30. A vent hole is provided through the liquid-blocking filter plate 40 along its axial direction. Further, in these embodiments, the middle part of the liquid-blocking filter plate 40 protrudes towards the constriction portion 11 along the axial direction of the liquid storage tank 10 to form a guide portion 41. A plurality of vent holes are provided through the liquid-blocking filter plate 40, and the plurality of vent holes are distributed around the guide portion 41. Thus, with such a structural design, the liquid refrigerant in the high-pressure gas flow can undergo large-area impact, thereby causing most of the liquid refrigerant to settle, effectively preventing most of the liquid refrigerant from flowing into the exhaust pipe 30 with the high-pressure gas flow. Furthermore, in these embodiments, a baffle plate 50 is provided in the exhaust chamber 13, located between the baffle filter plate 40 and the exhaust pipe 30. The baffle plate 50 is fixedly installed on the inner wall of the exhaust chamber 13, and a gas passage is formed through the baffle plate 50 along the axial direction of the liquid storage tank 10. With this structural design, when the high-pressure airflow passes through the baffle filter plate 40, it impacts the baffle plate 50 again, thereby further improving the settling effect of the liquid refrigerant. Thus, through the triple settling effect of the constricted end of the silencer chamber 12, the baffle filter plate 40, and the baffle plate 50, the risk of liquid refrigerant entering the compressor pump body with the high-pressure airflow can be more effectively reduced.

[0040] Optionally, in some embodiments of the present invention, the pipe fitting connector 20 includes an integrally formed pressure plate connector 21 and a connecting pipe 23. The pressure plate connector 21 is provided with a pipe fitting connection hole 22, the connecting pipe 23 is connected to the pipe fitting connection hole 22, and the connecting pipe 23 is connected to one end of the opening of the liquid storage tank 10.

[0041] Please see Figure 5 , Figure 5 This is a simulation vector diagram of the gas-liquid two-phase velocities of the horizontal liquid storage device according to an embodiment of this utility model. Figure 5 As shown, the gas and liquid phases enter from the opening end of the storage tank 10, are slowed down by the constriction section 11, and then enter the exhaust chamber 13. After being slowed down again by the liquid baffle plate 40 and the liquid baffle plate 50 in the exhaust chamber 13, the speed is greatly reduced, so that more liquid remains inside the storage tank 10, greatly reducing the amount of liquid discharged from the exhaust pipe 30, and the anti-liquid hammer effect is better.
