Description

Technical Field

[0001] The present application relates to the technical field of horizontal compressors, and in particular to a shell and tube structure for a horizontal compressor and a horizontal compressor. Background Art

[0002] A horizontal compressor is one in which the centerline of the cylinder is horizontal. In a horizontal compressor, after the refrigerant is compressed in the scroll, it typically flows along the gas path to the lower shell and is discharged through the exhaust pipe of the lower shell.

[0003] At present, when the refrigerant in the horizontal compressor flows to the lower shell component, it will form a circulation in the lower shell component and disturb the oil pool in the lower shell component, causing part of the refrigeration oil to be discharged along with the refrigerant, causing the oil to rise and increase, thereby reducing the heat exchange performance of the system. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a shell and tube structure for a horizontal compressor and a horizontal compressor, so as to solve the problem in existing horizontal compressors that the refrigerant disturbs the oil pool in the lower shell component, causing the oil to rise and increase.

[0005] According to a first aspect of the present invention, a tube shell structure for a horizontal compressor is provided, wherein the tube shell structure for a horizontal compressor includes: a tube shell portion, wherein refrigeration oil is arranged inside the tube shell portion; a lower shell portion, which is arranged at the end of the tube shell portion; a baffle, which is arranged between the tube shell portion and the lower shell portion; and an oil storage tank, which is formed at the bottom of the tube shell portion, and the oil storage tank is connected to the tube shell portion.

[0006] Preferably, the tube shell portion is cylindrical in shape.

[0007] Preferably, the bottom of the oil storage tank protrudes from the tube shell portion.

[0008] Preferably, the bottom surface of the oil storage tank is rectangular, and the depth direction of the oil storage tank is perpendicular to the axial direction of the tube shell portion.

[0009] Preferably, the length of the oil storage tank is less than or equal to the diameter of the tube shell portion.

[0010] Preferably, the oil storage tank is provided at an end portion of the tube shell portion close to the baffle.

[0011] Preferably, the baffle is provided with a through hole.

[0012] Preferably, the through hole is provided in the middle of the baffle or in the upper part of the baffle.

[0013] Preferably, an upper shell portion is provided at the end of the tube shell portion away from the lower shell portion, an air intake pipe is provided at the upper portion of the upper shell portion, and an exhaust pipe is provided at the upper portion of the lower shell portion.

[0014] According to a second aspect of the present invention, a horizontal compressor is provided, wherein the horizontal compressor includes the shell and tube structure for the horizontal compressor as described above.

[0015] The shell and tube structure for a horizontal compressor and the horizontal compressor of the embodiment of the utility model are provided with refrigeration oil inside the shell and tube portion. The lower shell portion is provided at the end of the shell and tube portion. A baffle is provided between the shell and tube portion and the lower shell portion to reduce the amount of refrigeration oil flowing to the lower shell portion. An oil storage tank is formed at the bottom of the shell and tube portion, and the oil storage tank is connected to the shell and tube portion for accommodating the refrigeration oil, so that the shell and tube portion can store more refrigeration oil, thereby reducing the amount of refrigeration oil in the lower shell portion. As a result, the amount of oil carried by the refrigerant gas when circulating in the lower shell portion is reduced, and the amount of oil discharged from the horizontal compressor is reduced. This can effectively solve the problem in existing horizontal compressors that the refrigerant will disturb the oil pool in the lower shell component, causing the oil to rise and increase.

[0030] like Figure 1 and Figure 2 As shown, according to a first aspect of the present invention, a tube shell structure for a horizontal compressor is provided. The tube shell structure for a horizontal compressor includes a tube shell portion 1 , a lower shell portion 2 , a baffle 3 and an oil storage tank 4 .

[0031] In the following description, reference will be made to Figure 1 and Figure 2 The specific structure of the above components of the shell and tube structure for a horizontal compressor and the connection relationship of the above components are described in detail.

[0032] like Figure 1 and Figure 2As shown, in the embodiment, refrigeration oil is provided inside the shell and tube portion 1, that is, an oil pool is formed inside the shell and tube portion 1. The lower shell portion 2 can be provided at the end of the shell and tube portion 1. A baffle 3 can be provided between the shell and tube portion 1 and the lower shell portion 2 to reduce the amount of refrigeration oil flowing to the lower shell portion 2. In addition, an oil storage tank 4 can be formed at the bottom of the shell and tube portion 1, and the oil storage tank 4 is connected to the shell and tube portion 1 for accommodating refrigeration oil, so that the shell and tube portion 1 can store more refrigeration oil, thereby reducing the amount of refrigeration oil in the lower shell portion 2. The amount of oil carried by the refrigerant gas when it circulates in the lower shell portion 2 is reduced, and the amount of oil discharged from the horizontal compressor is reduced.

[0033] Preferably, Figure 1 and Figure 2 As shown, in the embodiment, the shape of the tube shell part 1 can be approximately cylindrical. The lower shell part 2 can be installed at the end of the tube shell part 1 in the length direction. Specifically, Figure 1 As shown, the lower shell portion 2 can be disposed at the left end of the tube shell portion 1 in the longitudinal direction. The tube shell portion 1 is connected to the lower shell portion 2, allowing refrigerant gas to flow between the tube shell portion 1 and the lower shell portion 2. The baffle 3 can be a circular plate. The baffle 3 can be welded to the inner wall of the tube shell portion 1, thereby reducing the amount of refrigeration oil flowing from the tube shell portion 1 to the lower shell portion 2.

[0034] Preferably, Figure 1 As shown, in the embodiment, the lower shell 2 can be an arc-shaped plate, and the lower shell 2 can be covered at the end of the tube shell 1 to surround the refrigeration oil in the tube shell 1. In addition, an upper shell 5 can be provided at the end of the tube shell 1 away from the lower shell 2. The shape of the upper shell 5 is similar to that of the lower shell 2. The upper shell 5 can be covered at the end of the tube shell 1 in the longitudinal direction. Specifically, as Figure 1 As shown, the upper shell portion 5 can be arranged at the right end of the tube shell portion 1 in the length direction.

[0035] Preferably, Figure 1 As shown, in an embodiment, an air inlet pipe 50 may be provided at the upper portion of the upper shell portion 5 for introducing refrigerant gas. Preferably, the air inlet pipe 50 may be provided along the axial direction of the tube shell portion 1. In addition, an exhaust pipe 10 may be provided at the upper portion of the lower shell portion 2 for discharging refrigerant gas. Preferably, the exhaust pipe 10 may be provided along the radial direction of the tube shell portion 1. This arrangement allows the refrigerant gas to enter from the upper portion of the upper shell portion 5, flow through the tube shell portion 1, and finally be discharged at the lower shell portion 2.

[0036] Further, such as Figure 1As shown, in an embodiment, a through hole (not shown) for passing the refrigerant can be opened on the baffle 3, so that the refrigerant gas can flow between the tube shell portion 1 and the lower shell portion 2. Specifically, the through hole can be opened in the middle of the baffle 3 or in the upper part of the baffle 3, that is, the position of the through hole can be higher than the liquid level of the refrigeration oil in the tube shell portion 1, so as to prevent the refrigeration oil from flowing into the lower shell portion 2 through the through hole and causing the oil to rise.

[0037] Preferably, Figure 1 As shown, in the embodiment, the bottom of the oil storage tank 4 can protrude from the shell portion 1. Specifically, the oil storage tank 4 can protrude downward from the shell portion 1 to accommodate more refrigeration oil. The oil storage tank 4 can be integrally formed with the shell portion 1.

[0038] Further, preferably, Figure 1 As shown, in the embodiment, the bottom surface of the oil storage tank 4 can be rectangular, that is, the oil storage tank 4 is formed as a rectangular groove. The depth direction of the oil storage tank 4 can be perpendicular to the axial direction of the tube shell 1, and the length direction of the oil storage tank 4 can be as follows: Figure 1 The length of the oil storage tank 4 can be less than or equal to the diameter of the tube shell 1 .

[0039] More preferably, Figure 1 As shown, in this embodiment, the oil reservoir 4 can be disposed on the side of the baffle 3. Specifically, the oil reservoir 4 can be disposed at the end of the tube shell 1 near the baffle 3, that is, the oil reservoir 4 is disposed close to the baffle 3. This arrangement increases the oil storage capacity within the tube shell 1, further reduces the amount of refrigeration oil in the lower shell 2, and thus reduces oil rise, thereby improving the heat exchange performance of the system.

[0040] In addition, if Figure 1 and Figure 2 As shown, according to a second aspect of the present utility model, a horizontal compressor is provided, which includes the shell and tube structure for the horizontal compressor as described above.

[0041] During use, a baffle 3 is positioned between the shell and tubular portion 1 and the lower shell 2, reducing the amount of refrigeration oil flowing into the lower shell 2. Furthermore, an oil reservoir 4 is provided at the bottom of the shell and tubular portion 1, increasing the refrigeration oil capacity of the shell and tubular portion 1 and further reducing the amount of refrigeration oil in the lower shell 2. This reduces the amount of oil carried by the refrigerant gas as it circulates within the lower shell 2, and reduces the amount of oil discharged from the horizontal compressor, thereby improving the system's heat exchange performance.

[0042] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them.
