Description

Technical Field

[0001] This application relates to the field of compressor technology, and in particular to a compressor and a heat exchange system. Background Technology

[0002] In air conditioning systems, the rolling rotor compressor mainly consists of a pump body, housing, liquid receiver, motor, etc. The liquid receiver has functions such as liquid storage, oil-gas separation, and oil return. These functions can be completely replaced by the oil separator and gas separator in the air conditioning system, so the liquid receiver on the compressor can be replaced by the intake pipe. However, the extension length of the intake pipe on existing compressors is generally large, making it difficult to guarantee the stability of the intake end of the intake pipe. Utility Model Content

[0003] The main objective of this application is to propose a compressor and a heat exchange system that aims to improve the poor stability of the intake end of the compressor's intake pipe.

[0004] To achieve the above objectives, the compressor proposed in this application includes:

[0005] The housing has an air inlet along a first direction;

[0006] An intake pipe extending along the first direction, one end of which is connected to the intake port; and

[0007] A connecting portion is disposed around the air intake pipe and connected to the housing.

[0008] In one embodiment, the connecting portion is welded to the housing.

[0009] In one embodiment, the connecting portion includes a collar, which is sleeved on the air intake pipe and connected to the housing.

[0010] In one embodiment, the connecting portion is disposed in the middle of the air intake pipe.

[0011] In one embodiment, in the first direction, the intake pipe has multiple pipe segments, and one of the pipe segments located in the middle position is designated as the middle pipe segment;

[0012] The connecting part is located in the intermediate pipeline section.

[0013] In one embodiment, the intermediate pipeline section is made of steel; and / or,

[0014] The plurality of the pipeline segments include end pipeline segments at both ends, the end pipeline segments being made of brass.

[0015] In one embodiment, the connecting portion includes a collar, which is sleeved on the intermediate pipe section and connected to the housing;

[0016] The intermediate pipe section has a wall thickness of D, a pipe length of L, a collar height of h, and a collar wall thickness of d, wherein:

[0017] 0.15L≤h≤0.3L, and / or, 2D≤d≤4D.

[0018] In one embodiment, the air inlet is configured to open in a second direction;

[0019] The intake pipe has a branch pipe section at one end, which extends in a second direction to be inserted into the intake port.

[0020] In one embodiment, along the second direction, a duct protrusion is formed on the outer side wall of the housing, protruding toward the air inlet pipe;

[0021] The air inlet is formed on the protrusion of the duct.

[0022] In one embodiment, along the second direction, the length of the conduit protrusion is L1, and the length of the branch pipe section is L2, wherein:

[0023] 0.5L1≤L2≤1.2L1.

[0024] In one embodiment, the housing has a plurality of air inlets arranged in the first direction;

[0025] The intake pipe has a main pipe section and a plurality of branch pipe sections connected to one end of the main pipe section, and the plurality of branch pipe sections are provided with a plurality of intake holes.

[0026] In one embodiment, the compressor includes a refrigeration compressor.

[0027] This application also proposes a heat exchange system comprising the compressor described above.

[0028] The technical solution provided in this application connects one end of the intake pipe to the air inlet of the housing, thus the end can be fixed. The main section of the intake pipe can be stably installed to the housing through the connecting part, thereby increasing the number of connection points between the intake pipe and the housing, and the intake pipe is more stably fixed, thus alleviating the problem of poor stability at the intake end of the intake pipe. Moreover, since the connecting part is arranged around the intake pipe, the connection between the connecting part and the intake pipe is a simple detachable connection, without damaging the structure of the intake pipe itself due to the connection between the connecting part and the intake pipe (for example, if the connecting part and the intake pipe are connected by screws, it is necessary to drill holes or weld nuts on the intake pipe, which will damage the integrity of the intake pipe itself, or require the intake pipe to have a thicker pipe wall).

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0037] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0038] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0039] In air conditioning systems, the rolling rotor compressor mainly consists of a pump body, housing, liquid receiver, motor, etc. The liquid receiver has functions such as liquid storage, oil-gas separation, and oil return. These functions can be completely replaced by the oil separator and gas separator in the air conditioning system, so the liquid receiver on the compressor can be replaced by the intake pipe. However, the extension length of the intake pipe on existing compressors is generally large, making it difficult to guarantee the stability of the intake end of the intake pipe.

[0040] Analysis of the above reasons shows that the existing compressor's intake pipe is usually only connected to the compressor body at the intake port, resulting in the lack of a connection foundation for the entire extension section of the intake pipe. A connection structure can be set in the middle of the intake pipe to improve the above problem.

[0041] In view of this, this application provides a compressor aimed at improving the poor stability of the intake end of the compressor's intake pipe. Wherein, Figure 1 A schematic diagram of the structure of an embodiment of the compressor provided in this application; Figure 2 for Figure 1 A cross-sectional structural diagram of the compressor.

[0042] Please see Figure 1 and Figure 2In one embodiment of this application, the compressor 100 includes a housing 1, an intake pipe 2, and a connecting part 3. The housing 1 has an intake hole 111 along a first direction; the intake pipe 2 extends along the first direction, and one end of the intake pipe 2 is connected to the intake hole 111; the connecting part 3 is arranged around the intake pipe 2 and connected to the housing 1.

[0043] It should be noted that the compressor 100 includes a compressor 100 body, and the housing 1 is the housing 1 of the compressor 100 body, on which an air inlet 111 is formed. The compressor 100 body usually also includes a cylinder disposed in the housing 1, and the cylinder communicates with the air inlet 111. In this application embodiment, no limitation is made on the working parts of the compressor 100 other than the housing 1, the air inlet pipe 2 and the connecting part 3.

[0044] The housing 1 of the compressor 100 usually has a height dimension, and the cylinder of the compressor 100 is usually located at the bottom. Therefore, the location of the air inlet 111 is usually also close to the bottom of the housing 1. "One end of the air inlet pipe 2 is connected to the air inlet 111" can be understood as the bottom end of the air inlet pipe 2 being connected to the air inlet 111. The connection also means that it is fixed.

[0045] "Intake pipe 2 extends along the first direction" should be understood as meaning that intake pipe 2 extends along the first direction as a whole, but some sections of it may tilt or extend in other directions.

[0046] The connecting part 3 can be arranged around the air intake pipe 2. There are many structural forms of the connecting part 3. For example, the connecting part 3 includes a steel wire rope wrapped around the air intake pipe 2. This embodiment does not limit the specific structural form of the connecting part 3. There are many ways to connect the connecting part 3 and the housing 1. For example, the connecting part 3 and the housing 1 can be detachably connected, or the connecting part 3 and the housing 1 can be integrally connected. This embodiment does not limit this.

[0047] The technical solution provided in this application connects one end of the intake pipe 2 to the air inlet 111 of the housing 1. Therefore, this end can be fixed. The main pipe section of the intake pipe 2 can be stably installed to the housing 1 through the connecting part 3, thereby increasing the number of connection points between the intake pipe 2 and the housing 1. The intake pipe 2 is more stably fixed, thus alleviating the problem of poor stability at the intake end of the intake pipe 2. Moreover, since the connecting part 3 is arranged around the intake pipe 2, the connection between the connecting part 3 and the intake pipe 2 is a simple detachable connection. It is not necessary to damage the structure of the intake pipe 2 itself due to the connection between the connecting part 3 and the intake pipe 2 (for example, if the connecting part 3 and the intake pipe 2 are connected by screws, it is necessary to drill holes or weld nuts on the intake pipe 2, which will damage the integrity of the intake pipe 2 itself, or require the intake pipe 2 to have a thicker pipe wall).

[0048] Compared to the traditional method of air intake through a liquid receiver, the present application reduces the radial dimension of the compressor 100 itself, saves the space required for compressor 100 installation, improves the rotational vibration of compressor 100, and optimizes the noise OA value.

[0049] Please see Figure 2 In some embodiments, the connecting part 3 is welded to the housing 1.

[0050] It should be noted that the welding method of the connecting part 3 to the housing 1 can be varied. For example, the connecting part 3 may abut against the peripheral wall of the housing 1 through its peripheral sidewall. In this case, there is a connecting line extending along the first direction between the connecting part 3 and the housing 1. Welding on both sides of the connecting line can ensure the connection between the connecting part 3 and the housing 1. Furthermore, if the housing 1 has a concave surface opposite to the connecting part 3, and the peripheral sidewall of the connecting part 3 fits and abuts against the concave surface of the housing 1, the connecting part 3 and the housing 1 are in surface contact. Welding at the periphery of the contact surface can ensure the stable connection between the connecting part 3 and the housing 1.

[0051] According to the above technical solution, the connecting part 3 and the housing 1 are connected by welding, that is, the connecting part 3 and the housing 1 are integrally set, so that the connecting part 3 and the housing 1 are not easy to separate, and the stable connection between the intake pipe 2 and the housing 1 can be maintained under the long-term vibration condition of the compressor 100.

[0052] Please see Figure 1 and Figure 2 In some embodiments, the connecting part 3 includes a collar 31, which is sleeved on the intake pipe 2 and connected to the housing 1. It should be noted that the collar 31 being sleeved on the intake pipe 2 can be understood as having a clearance fit with the intake pipe 2, allowing the collar 31 to be inserted from one end of the intake pipe 2 and slide on the intake pipe 2 to adjust its installation position. The collar 31 can be connected in two ways: detachable connection and fixed connection, which is not limited in this embodiment.

[0053] According to the above technical solution, the collar 31 is sleeved on the intake pipe 2, and the working area between it and the intake pipe 2 is large, so that the surface of the intake pipe 2 will not be damaged during the connection process. At the same time, the rigidity of the sleeve is good, which can restrict the movement of the intake pipe 2 in all radial directions and ensure the connection stability of the intake pipe 2.

[0054] In the above embodiments, except for the end of the intake pipe 2 that connects to the intake port 111 (for ease of description, the end of the intake pipe 2 that connects to the intake port 111 is referred to as the connecting end), the connecting part 3 can be set at any position on the intake pipe 2. Since the intake pipe 2 has been connected and fixed at the connecting part, the connecting part 3 is usually set close to the intake end of the intake pipe 2. However, the closer the connecting part 3 is to the intake end of the intake pipe 2, the more stable the connection between the intake pipe 2 and the housing 1 is, because there is a large span between the connecting part 3 and the connecting end of the intake pipe 2. In view of this, in some embodiments, the connecting part 3 is set in the middle of the intake pipe 2.

[0055] According to the above technical solution, by setting the connecting part 3 in the middle of the air intake pipe 2, it can ensure that the span of the air intake pipe 2 between the connecting part 3 and the air intake hole 111 is within a suitable range, thus ensuring the rigidity of the air intake pipe 2. At the same time, the span between the air intake end of the air intake pipe 2 and the connecting part 3 is not too large. The connecting part 3 can effectively improve the stability of the air intake end of the air intake pipe 2.

[0056] Furthermore, in some embodiments, in the first direction, the intake pipe 2 has multiple pipe segments 2a, and one pipe segment 2a in the middle position is set as the middle pipe segment 21; the connecting part 3 is provided in the middle pipe segment 21.

[0057] It should be noted that "the intake pipe 2 has multiple pipe sections 2a" can be understood as multiple pipe sections 2a being arranged along the first direction, and two adjacent pipe sections 2a being connected end to end. The connection method can be, for example, a threaded connection or a sealant connection. This embodiment does not limit this.

[0058] Compared to directly molding the intake pipe 2 as a single piece, setting the intake pipe 2 as a series of interconnected pipe segments 2a allows for the separate processing of multiple shorter pipe segments 2a, which obviously reduces processing difficulty and the specifications of processing equipment. Moreover, when the intake pipe 2 is molded as a single piece, if there is a defect in a part of the intake pipe 2, it can easily lead to the scrapping of the entire intake pipe 2. However, in this embodiment, if one of the pipe segments 2a is defective, only that pipe segment 2a needs to be replaced, which can reduce the amount of waste generated by the intake pipe 2.

[0059] Furthermore, in some embodiments, the intermediate pipe section 21 is made of steel; and / or, the plurality of pipe sections 2a include end pipe sections 22 at both ends, the end pipe sections 22 being made of brass.

[0060] It should be noted that the two parallel technical features mentioned above, "the material of the intermediate pipe section 21 includes steel" and "the multiple pipe sections 2a include end pipe sections 22 at both ends, and the material of the end pipe sections 22 includes brass", can be selected or provided simultaneously. The multiple pipe sections 2a may include only one intermediate pipe section 21 and two end pipe sections 22, or they may include other pipe sections 2a. This embodiment does not limit this.

[0061] According to the above technical solution, the intermediate pipe section 21 is used to connect with the connecting part 3. It is more appropriate to make it steel, as steel has a high hardness, which can prevent the connecting part 3 from scratching the intermediate pipe section 21 during the connection process, and also prevent the intermediate pipe section 21 from deforming. The intermediate pipe section 21 is used to connect with the air intake pipe 2 of the cylinder inside the housing 1, or with the external system pipe. Regardless of whether it is the air intake pipe 2 of the cylinder or the external system pipe, its material is usually brass. Therefore, making the end pipe section 22 brass is convenient for welding with other copper pipes, and can also prevent rusting.

[0062] Specifically, in some embodiments, the connecting part 3 is sleeved on the intermediate pipe section 21 and welded to the housing 1, and the intermediate pipe section 21 is made of steel. With this arrangement, during the welding process between the connecting part 3 and the housing 1, the intermediate pipe section 21 is subjected to high temperatures, but because it is made of steel, oxide scale can be avoided from forming on the inner wall of the intermediate pipe section 21, thus ensuring the safe operation of the cylinder inside the housing 1.

[0063] Specifically, please refer to Figure 1 In some embodiments, the connecting part 3 includes a collar 31, which is sleeved on the intermediate pipe section 21 and integrally connected to the housing 1; the wall thickness of the intermediate pipe section 21 is D, the pipe length of the intermediate pipe section 21 is L, the height of the collar 31 is h, and the wall thickness of the collar 31 is d, wherein: 0.15L≤h≤0.3L, and / or, 2D≤d≤4D.

[0064] It should be noted that the two parallel technical features “0.15L≤h≤0.3L” and “2D≤d≤4D” can be set individually or simultaneously. Obviously, setting them simultaneously will have a better effect.

[0065] In this embodiment, the "pipe length L of the intermediate pipe section 21" and the "height h of the collar 31" are associated. The condition 0.15L≤h≤0.3L means that h can be 0.15 times, 0.2 times, 0.25 times or even 0.3 times L, or any value within the above range. This application does not limit the specific multiple relationship between the "pipe length L of the intermediate pipe section 21" and the "height h of the collar 31".

[0066] In this embodiment, the wall thickness dimension D of the intermediate pipe section 21 is associated with the wall thickness dimension d of the collar 31. Here, 2D≤d≤4D means that d can be 2 times, 2.5 times, 3 times, 3.5 times or even 4 times D, or any value within the above range. This application does not limit the specific multiple relationship between the wall thickness dimension D of the intermediate pipe section 21 and the wall thickness dimension d of the collar 31.

[0067] According to the above technical solution, setting the "height h of collar 31" to between 0.15 and 0.3 times the "pipe length L of intermediate pipe section 21" is more reasonable. This ensures that collar 31 and intermediate pipe section 21 have sufficient contact area while limiting the material usage of collar 31 within a reasonable range, thus controlling the production cost of collar 31. At the same time, setting the "wall thickness d of collar 31" to between 2 and 4 times the "wall thickness D of intermediate pipe section 21" is more reasonable. This ensures that collar 31 has sufficient connection strength to intermediate pipe section 21 while avoiding excessive strength of collar 31, and also limits the material usage of collar 31 within a reasonable range.

[0068] In the above embodiments, only the intake pipe 2 is limited to extending along the first direction, with one end of the intake pipe 2 connected to the intake port 111. The opening direction of the intake port 111 can be varied, requiring only an adaptive adjustment of the shape of the housing 1. For example, the opening direction can face the first direction, in which case one end of the intake pipe 2 opens towards the first direction. However, under normal circumstances, the housing 1 is cylindrical, and the intake port 111 is generally located on the peripheral sidewall of the housing 1. Based on this, please refer to... Figure 1 In some embodiments, the air inlet 111 is provided to open in the second direction; the air inlet pipe 2 has a branch pipe section 23 at one end, which extends in the second direction to be inserted into the air inlet 111.

[0069] It should be noted that the length of the branch pipe section 23 along the second direction is usually a small proportion of the total length of the intake pipe 2, and does not affect the judgment that the intake pipe 2 extends in the first direction as a whole; the second direction is usually a direction that is set at an angle to the first direction. Generally speaking, the second direction is perpendicular to the first direction. For example, the second direction is the radial direction of the housing 1, and the first direction is the height direction of the housing 1.

[0070] According to the above technical solution, the branch pipe section 23 is inserted into the air inlet 111 along the second direction. While ensuring the sealing performance, the air inlet pipe 2 can be closer to the housing 1, thereby further reducing the overall size of the compressor 100 in the second direction.

[0071] Generally, to account for the overall wall thickness of the housing 1, the depth of the air inlet 111 cannot be set too deep. This results in insufficient support for the branch pipe section 23 within the air inlet 111 of the housing 1, which is detrimental to ensuring a stable connection between the air intake pipe 2 and the housing 1. Therefore, please refer to... Figure 1 In some embodiments, along the second direction, a conduit protrusion 11 is formed on the outer side wall of the housing 1 facing the air inlet pipe 2; an air inlet 111 is formed on the conduit protrusion 11.

[0072] It should be noted that the duct protrusion 11 can be understood as a branch pipe section 23 specifically for the air intake pipe 2 to be inserted, which is used to form the air intake hole 111. Since the duct protrusion 11 protrudes in the second direction, the air intake hole 111 can be set deeper by overcoming the limitation of the overall wall thickness of the housing 1.

[0073] According to the above technical solution, by setting the duct protrusion 11, sufficient insertion depth can be provided for the branch pipe section 23 of the air intake pipe 2, which is conducive to ensuring a stable connection between the branch pipe section 23 and the duct protrusion 11, and improving the sealing performance of the branch pipe section 23 in the duct protrusion 11.

[0074] Further, please refer to Figure 1 and Figure 2 In some embodiments, along the second direction, the length of the conduit protrusion 11 is L1, and the length of the branch pipe section 23 is L2, wherein: 0.5L1≤L2≤1.2L1.

[0075] It should be noted that in this embodiment, the "length dimension L2 of the intake branch pipe section 23" and the "length dimension L1 of the duct protrusion 11" are associated. The condition 0.5L1≤L2≤1.2L1 means that L2 can be 0.5 times, 0.7 times, 0.9 times or even 1.2 times L1, or any value within the above range. This application does not limit the specific multiple relationship between the "length dimension L2 of the intake branch pipe section 23" and the "length dimension L1 of the duct protrusion 11".

[0076] According to the above technical solution, it is reasonable to set the "length dimension L2 of intake branch pipe section 23" between 0.5 and 1.2 times the "length dimension L1 of duct protrusion 11", which can ensure that the branch pipe section 23 has sufficient insertion depth in the duct protrusion 11.

[0077] Furthermore, please refer to Figure 2 In some embodiments, the housing 1 has a plurality of air inlets 111 arranged in a first direction; the air inlet pipe 2 has a main pipe section 24 and a plurality of branch pipe sections 23 connected to one end of the main pipe section 24, the plurality of branch pipe sections 23 being provided corresponding to the plurality of air inlets 111.

[0078] It should be noted that in this embodiment, the intake pipe 2 is functionally divided into a main pipe section 24 and multiple branch pipe sections 23. The main pipe section 24 is used for air intake, and the branch pipe sections 23 are used for connecting and venting. In other embodiments, the intake pipe 2 can also be divided into multiple pipe sections 2a connected in the first direction. The air inlet 111 connects to the cylinder inside the housing 1 of the compressor 100. Therefore, the presence of multiple air inlets 111 indicates that the compressor 100 is a multi-cylinder compressor 100.

[0079] In this technical solution, the compressor 100 is provided with multiple air holes and multiple branch pipe sections 23, and multiple cylinders can be uniformly intake air through the intake pipe 2. Compared with the compressor 100 with a single air hole 111, the compressor 100 with multiple air holes 111 in this embodiment has a larger output power.

[0080] The compressor 100 provided in this application embodiment has many specific types. Specifically, the compressor 100 includes, but is not limited to, a refrigeration compressor.

[0081] This application also proposes a heat exchange system, which includes a compressor 100. The specific structure of the compressor 100 is as described in the above embodiments. Since this heat exchange system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The heat exchange system includes, but is not limited to, air conditioning systems and refrigeration systems. It is understood that when the compressor 100 is specifically configured as a refrigeration compressor, the heat exchange system is specifically configured as a refrigeration system.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application, and they should all be covered within the scope of the claims and specification of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way.
