Description

Technical Field

[0001] This utility model relates to the field of compressors, and in particular to a horizontal rotary compressor for vehicles, an air conditioning system, and a vehicle. Background Technology

[0002] The compressor's internal structure is divided into a high-pressure chamber and a low-pressure chamber, separated by a partition. The temperature in the high-pressure chamber is higher, while the temperature in the low-pressure chamber is lower. Heat is transferred from the high-pressure chamber to the low-pressure chamber through the partition, especially when the temperature rise in the high-pressure chamber is significant, increasing the temperature difference and exacerbating heat conduction. This causes the temperature of the low-temperature refrigerant in the low-pressure chamber to rise, resulting in vapor expansion, reduced suction efficiency and volumetric efficiency, and increased energy consumption due to superheated gas.

[0003] Therefore, there is room for improvement in the compressor. Utility Model Content

Detailed Implementation

[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0039] In the description of this utility model, it should be understood that the terms "center," "upper," "lower," "top," "bottom," "inner," "outer," "axial," and "radial," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0040] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] The following is for reference. Figure 1 - Figure 6 This invention describes a vehicle horizontal rotary compressor 100 according to an embodiment of the present invention. The vehicle horizontal rotary compressor 100 of the present invention can be a single-cylinder single-exhaust compressor, a single-cylinder double-exhaust compressor, a double-cylinder compressor, etc.

[0042] It is worth noting that the vehicle horizontal rotary compressor 100 of this utility model embodiment is used in vehicle 1000 to meet the high load requirements of vehicle 1000. The specific use of vehicle horizontal rotary compressor 100 in vehicle 1000 is not limited. It can be applied to air conditioning system 200 to provide the compression power required for cooling or heating, and can also be flexibly configured in equipment such as refrigerators, heat pump water heaters, and thermal management systems for new energy vehicles.

[0043] In some embodiments, the refrigerant used in the automotive horizontal rotary compressor 100 is carbon dioxide, and the automotive horizontal rotary compressor 100 is a carbon dioxide compressor. Of course, the refrigerant used in the automotive horizontal rotary compressor 100 is not limited to this. The use of carbon dioxide as the refrigerant in the automotive horizontal rotary compressor 100 has many advantages.

[0044] Carbon dioxide, when used as a refrigerant, has a relatively high intake and exhaust pressure compared to traditional refrigerants. The automotive horizontal rotary compressor 100 of this embodiment can meet the sealing requirements when using carbon dioxide as a refrigerant. Furthermore, carbon dioxide has excellent thermodynamic properties; therefore, when the same cooling capacity is required, the volume of the compressor's compression chamber does not need to be excessively large when using carbon dioxide as the refrigerant, allowing for a reduction in the volume of the compression chamber and thus reducing the overall size and weight of the compressor. In addition, the compressor using carbon dioxide can operate over a wide pressure range, exhibiting stable performance whether performing initial compression under low pressure or deep compression under high pressure. Therefore, the automotive horizontal rotary compressor 100 of this application can achieve an optimized compression ratio, providing highly efficient cooling performance when used in a refrigeration system, thereby reducing energy consumption and improving energy utilization.

[0045] This application improves the heat insulation structure of the compressor, further increasing the compression ratio. Since carbon dioxide, as a refrigerant, achieves a high compression ratio, the increase in compression ratio is more pronounced in the automotive horizontal rotary compressor 100 using carbon dioxide.

[0046] like Figure 1 As shown, the vehicle horizontal rotary compressor 100 according to the first aspect embodiment of the present invention includes: a first housing 10, a second housing 20, a partition 30, a compression mechanism 40, and a crankshaft 50.

[0047] The first housing 10 and the second housing 20 serve as the main external structures of the automotive horizontal rotary compressor 100. Their primary function is to provide a robust support frame to protect the complex and precise mechanical components inside the automotive horizontal rotary compressor 100 from interference and damage from the external environment. These two housings ensure the stability and durability of the overall structure of the automotive horizontal rotary compressor 100.

[0048] The first housing 10 is provided with an exhaust port (not shown in the figure). This exhaust port is the passage for the high-pressure gas inside the vehicle horizontal rotary compressor 100 to be discharged.

[0049] The partition 30 is disposed between the first housing 10 and the second housing 20. The first housing 10 and the partition 30 form a first cavity 11, and the second housing 20 and the partition 30 form a second cavity 21. The partition 30 is provided with a through hole 31 and an air intake channel (not shown) communicating with the air inlet (not shown).

[0050] The partition 30, as a component separating the first cavity 11 and the second cavity 21, not only serves as a physical barrier, but also enables the reasonable flow and distribution of gas within the vehicle horizontal rotary compressor 100 through the through hole 31 and the air intake channel on it.

[0051] The intake passage is located on the partition 30 and is responsible for introducing low-pressure gas from the outside into the automotive horizontal rotary compressor 100 for compression. The intake passage ensures that the automotive horizontal rotary compressor 100 continuously and stably draws in sufficient low-pressure gas for compression.

[0052] The air inlet is used to introduce low-pressure gas from the outside into the second chamber 21 for compression. In some alternative embodiments, the air inlet is located on the second housing 20. This arrangement allows low-pressure gas from the outside to be directly introduced into the second chamber 21 inside the automotive horizontal rotary compressor 100 through the air inlet on the second housing 20, and then directly into the first chamber 11 through the air intake passage on the partition 30. The first chamber 11 serves as the main area for gas compression processing inside the automotive horizontal rotary compressor 100, where low-pressure gas is compressed.

[0053] Alternatively, the air inlet can be located on the partition 30 and connected to the air intake channel. This allows low-pressure external gas to directly enter the air intake channel through the air inlet on the surface of the partition 30, and then quickly and directly flow into the first chamber 11 for compression. This arrangement not only shortens the path of gas into the automotive horizontal rotary compressor 100, reducing resistance and turbulence during gas flow, but also improves intake efficiency.

[0054] Optionally, at least one of the air inlet and air intake passage is provided with a filter device. The filter device is used to remove impurities and particulate matter from the low-pressure gas, ensuring that the gas entering the second chamber 21 is pure and uncontaminated, thereby protecting the internal components of the second chamber 21 from damage and improving the reliability of the automotive horizontal rotary compressor 100.

[0055] The compression unit 40, as the core component of the automotive horizontal rotary compressor 100, is responsible for compressing the incoming refrigerant and converting it into high-pressure refrigerant before discharging it.

[0056] The compression mechanism 40 is located inside the first cavity 11. The compression mechanism 40 is connected to the air intake channel to compress the incoming refrigerant, and the compression mechanism 40 is connected to the exhaust port to discharge the refrigerant.

[0057] The compression mechanism 40 is located within the first cavity 11 precisely to fully utilize the enclosed and stable working environment provided by the first cavity 11. The compression mechanism 40 typically includes multiple precision mechanical components, such as pistons, cylinders, crankshafts 50, connecting rods (or screws and scrolls in screw or scroll compressors), etc. These components are interconnected through complex mechanical structures and transmission devices, working together to complete the refrigerant compression task. Therefore, placing the compression mechanism 40 within the first cavity 11 enhances its protection and improves the stability and reliability of the automotive horizontal rotary compressor 100.

[0058] When the compressor section 40 is operating, the external low-pressure refrigerant first enters the intake passage through the intake port, and then enters the compressor section 40 under the guidance of the intake passage. Once the refrigerant enters the compressor section 40, the compression process begins. Depending on the type of automotive horizontal rotary compressor 100 (such as piston, screw, scroll, etc.), the specific implementation of the compression process will vary. However, generally speaking, the mechanical components within the compressor section 40 will reciprocate or rotate under the action of driving force to compress the refrigerant. During this process, the volume of the refrigerant gradually decreases, the pressure gradually increases, and its temperature and energy also increase accordingly.

[0059] Finally, the high-pressure refrigerant, after being compressed by the compression mechanism 40, is discharged from the vehicle horizontal rotary compressor 100 through the exhaust port on the first housing 10.

[0060] To improve the efficiency of refrigerant entering the compression unit 40, a drive component (not shown) is provided in the second cavity 21. Here, the drive component can participate in the flow control of the refrigerant, and may also improve the flow efficiency of the refrigerant by optimizing the airflow path and enhancing gas dynamics, thereby improving the overall efficiency of the automotive horizontal rotary compressor 100.

[0061] Optionally, the driving component is an airflow guide. The airflow guide includes, but is not limited to, blades, deflectors, or vortex generators, to guide the refrigerant airflow more smoothly into the compressor section 40. The airflow guide can also reduce resistance and vortices during the refrigerant airflow process, improving intake efficiency.

[0062] Alternatively, the driving component may be a pre-compression device, located between the intake passage and the compression mechanism 40. The pre-compression device can be a small piston, propeller, or scroll plate, which compresses the refrigerant to a certain extent before it enters the compression mechanism 40 within the second chamber 21. Pre-compression reduces the load on the compression mechanism 40 of the second chamber 21, thereby helping to improve the overall efficiency of the automotive horizontal rotary compressor 100.

[0063] The crankshaft 50 is disposed in the through hole 31 of the partition plate 30, and the two ends of the crankshaft 50 are respectively engaged with the compression mechanism 40 and the drive component.

[0064] It is known that the crankshaft 50 is an important component connecting the drive unit and the compression mechanism 40. It is usually a long strip-shaped shaft so that both ends can be matched with the compression mechanism 40 and the drive unit respectively.

[0065] The partition 30 serves to support and position the crankshaft 50. It not only provides a stable installation environment for the crankshaft 50 but also restricts its movement trajectory through its through-hole 31. Therefore, the through-hole 31 in the partition 30 is adapted to the external dimensions of the crankshaft 50 to ensure smooth passage. The through-hole 31 also takes into account the diameter and length of the crankshaft 50 to ensure that the crankshaft 50 is not unnecessarily obstructed or damaged during installation and operation.

[0066] Specifically, when the automotive horizontal rotary compressor 100 is working, the drive component can drive the crankshaft 50 to move, which in turn causes the crankshaft 50 to drive the piston of the compression mechanism 40 to work, so that the refrigerant can enter the intake passage from the intake port. Then, the refrigerant enters the compression mechanism 40 from the intake passage. Through the volume change of the compression chamber in the compression mechanism 40, the refrigerant is compressed and changed, so that the refrigerant becomes a high-pressure, high-temperature gas, and then is discharged from the exhaust port.

[0067] In order to further improve the problems mentioned in the background art and maintain the efficient operation of the vehicle horizontal rotary compressor 100, the vehicle horizontal rotary compressor 100 of this utility model embodiment also includes a heat insulation pad 60.

[0068] like Figure 1 As shown, the main function of the heat insulation pad 60 is to act as a thermal barrier, effectively reducing the heat flow between the first cavity 11 and the second cavity 21. Through the efficient heat insulation performance of the heat insulation pad 60, the temperature rise of the partition 30 due to heat conduction can be reduced, thereby maintaining the low-pressure, low-temperature refrigerant at a low temperature before entering the first cavity 11.

[0069] Due to the heat insulation effect of the heat insulation pad 60, the heat absorbed by the low-pressure, low-temperature refrigerant as it flows through the partition 30 is reduced, and its temperature and density can remain relatively stable. This stable refrigerant state helps the automotive horizontal rotary compressor 100 achieve higher compression efficiency during the intake process.

[0070] Therefore, the introduction of the heat insulation pad 60 not only reduces unnecessary heat loss, but also maintains the best condition when the refrigerant enters the vehicle horizontal rotary compressor 100, thereby ensuring the operating efficiency of the vehicle horizontal rotary compressor 100.

[0071] The heat insulation pad 60 includes a first heat insulation pad 61, which is disposed on at least one side of the partition 30.

[0072] In some alternative embodiments, the first heat insulation pad 61 is disposed on the side facing the first cavity 11. The first heat insulation pad 61 can directly block the direct heat radiation and heat conduction of the high-pressure, high-temperature refrigerant to the partition 30. This arrangement helps to reduce the impact of the high-temperature refrigerant on the temperature of the partition 30, thereby indirectly protecting the low-temperature refrigerant in the second cavity 21 from premature heating.

[0073] Alternatively, the first heat insulation pad 61 may be located on the side facing the second cavity 21. In this way, the first heat insulation pad 61 can prevent heat conduction from the partition 30 to the second cavity 21, thus avoiding unnecessary heating of the low-temperature refrigerant as it flows through the partition 30.

[0074] Alternatively, to improve the thermal insulation between the first cavity 11 and the second cavity 21, first thermal insulation pads 61 are disposed on both sides of the partition 30, with one first thermal insulation pad 61 facing the first cavity 11 and the other facing the second cavity 21. This double-sided arrangement minimizes heat flow between the two cavities, ensuring that the low-temperature, low-pressure refrigerant maintains optimal temperature and density before entering the first cavity 11, thereby improving the overall efficiency and stability of the automotive horizontal rotary compressor 100.

[0075] In some alternative embodiments, the material of the heat insulation pad 60 has low thermal conductivity. This reduces heat transfer, resulting in minimal or no temperature rise in the second housing 20.

[0076] The thermal conductivity of the material of the heat insulation pad 60 may be less than that of the material of the first shell 10, or the thermal conductivity of the material of the heat insulation pad 60 may be less than that of the material of the second shell 20, or the thermal conductivity of the material of the heat insulation pad 60 may be less than that of both the material of the first shell 10 and the material of the second shell 20.

[0077] In some optional embodiments, the thermal conductivity of the material of the heat insulation pad 60 is λ1, the thermal conductivity of the material of the partition 30 is λ2, and the minimum thermal conductivity of the material in the first housing 10 and the second housing 20 is λ3, wherein λ1≤λ3 and λ2≤λ3.

[0078] The thermal conductivity of the materials of the first shell 10 and the second shell 20 can be equal or unequal. The minimum thermal conductivity of the materials of the first shell 10 and the second shell 20 can be called λ2. The thermal conductivity of the materials of the heat insulation pad 60 and the partition plate 30 can be equal or unequal. As long as the thermal conductivity λ1 of the heat insulation pad 60 and the thermal conductivity λ2 of the partition plate 30 are both less than λ3, the heat transfer between the first shell 10 and the second shell 20 can be effectively blocked.

[0079] According to some embodiments of the present invention, the vehicle horizontal rotary compressor 100 includes at least one of a first annular heat insulation pad 611 and a second annular heat insulation pad 612; wherein the first annular heat insulation pad 611 is located at the edge of the partition 30 and is sandwiched on the side of the partition 30 facing the first housing 10; the second annular heat insulation pad 612 is located at the edge of the partition 30 and is sandwiched on the side of the partition 30 facing the second housing 20.

[0080] It is worth noting that the edges of the partition 30 are often sensitive areas for heat transfer, as these areas are more susceptible to the influence of the external environment or adjacent components. The first annular heat insulation pad 611 and the second annular heat insulation pad 612 are located on the two sides of the partition 30 facing the first cavity 11 and the second cavity 21, respectively. By adding an additional heat insulation layer 601, the heat transfer of the high-temperature, high-pressure refrigerant in the first cavity 11 to the second cavity 21 through the edges of the partition 30 is reduced. Simultaneously, they also block the path of heat that might be absorbed from the outside of the automotive horizontal rotary compressor 100 by the edges of the partition 30 into the second cavity 21, thereby ensuring the temperature stability of the low-temperature, low-pressure refrigerant in the second cavity 21 and optimizing the overall heat insulation effect and operating efficiency of the automotive horizontal rotary compressor 100.

[0081] In some embodiments, the first heat insulation pad 61 includes a first annular heat insulation pad 611, which is located at the edge of the partition 30 and sandwiched between the partition 30 and the side facing the first housing 10. Because the first annular heat insulation pad 611 is tightly fitted to the edge of the partition 30 and faces the first cavity 11, it can more effectively block the heat of the high-pressure, high-temperature refrigerant from penetrating into the second cavity 21, ensuring that the low-pressure refrigerant maintains a lower temperature before entering the first cavity 11.

[0082] Alternatively, the first heat insulation pad 61 may include a second annular heat insulation pad 612, which is located at the edge of the partition 30 and sandwiched between the partition 30 and the side of the partition 30 facing the second housing 20. This arrangement prevents heat absorbed from the outside of the automotive horizontal rotary compressor 100 by the edge of the partition 30 from being transferred to the second cavity 21, thereby protecting the temperature stability of the low-pressure refrigerant and maintaining the overall performance of the automotive horizontal rotary compressor 100.

[0083] Or, as Figure 1 As shown, the first heat insulation pad 61 includes a first annular heat insulation pad 611 and a second annular heat insulation pad 612. The first annular heat insulation pad 611 is located at the edge of the partition 30 and is sandwiched between the sides of the partition 30 facing the first housing 10, while the second annular heat insulation pad 612 is located at the edge of the partition 30 and is sandwiched between the sides of the partition 30 facing the second housing 20. This dual heat insulation design forms a relatively complete heat insulation barrier, ensuring the operating efficiency of the automotive horizontal rotary compressor 100.

[0084] According to some embodiments of the present invention, a horizontal rotary compressor 100 for vehicles, such as... Figure 2 - Figure 4As shown, the first heat insulation pad 61 includes at least one of a first surface heat insulation pad 613 and a second surface heat insulation pad 614. The first surface heat insulation pad 613 covers the surface of the partition 30 facing the first cavity 11. The second surface heat insulation pad 614 covers the surface of the partition 30 facing the second cavity 21. The first surface heat insulation pad 613 and the second surface heat insulation pad 614 are provided with a first clearance hole 6131 for avoiding the through hole 31 and a second clearance hole (not shown) for avoiding the air intake passage.

[0085] The first type of heat insulation pad 613 and the second type of heat insulation pad 614 are used to cover the two main surfaces of the partition 30 to provide a more comprehensive heat insulation effect.

[0086] Among them, such as Figure 3 As shown, a first heat-insulating pad 613 covers the surface of the partition 30 facing the first cavity 11. This reduces the contact area between the first cavity 11 and the partition 30, preventing direct heat transfer from the first cavity 11 to the partition 30 and reducing heat penetration into the second cavity 21, thus maintaining a low-temperature environment within the second cavity 21. A first clearance hole 6131 is provided on the first heat-insulating pad 613 to ensure that the through-hole 31 on the partition 30 is not blocked, allowing the crankshaft 50 to pass smoothly through the first heat-insulating pad 613. A second clearance hole is provided on the first heat-insulating pad 613 to keep the air intake passage unobstructed, thus not affecting the normal operation of the automotive horizontal rotary compressor 100.

[0087] like Figure 4 As shown, a second-face heat insulation pad 614 covers the surface of the partition 30 facing the second cavity 21. The main function of the second-face heat insulation pad 614 is to prevent the heat absorbed by the partition 30 from the first cavity 11 from being transferred to the second cavity 21, thereby maintaining the low temperature of the refrigerant in the second cavity 21. The second-face heat insulation pad 614 is also provided with a first clearance hole 6131 and a second clearance hole to match the through hole 31 and the air intake channel on the partition 30, ensuring the structural integrity and normal functioning of the automotive horizontal rotary compressor 100.

[0088] In some embodiments, such as Figure 3 As shown, the first heat insulation pad 61 includes only the first surface heat insulation pad 613. Alternatively, the first heat insulation pad 61 includes only the second surface heat insulation pad 614. Both methods can achieve the heat insulation effect of the first heat insulation pad 61.

[0089] Or, as Figure 4As shown, to further improve the heat insulation effect of the first cavity 11 and the second cavity 21, the first heat insulation pad 61 includes: a first surface heat insulation pad 613 and a second surface heat insulation pad 614. By providing double heat insulation to both sides of the partition 30, the operating efficiency of the vehicle horizontal rotary compressor 100 is ensured.

[0090] like Figure 4 As shown, in some embodiments of the present invention, the vehicle horizontal rotary compressor 100 includes a first heat insulation pad 61 comprising a first surface-shaped heat insulation pad 613. The edge of the first surface-shaped heat insulation pad 613 is sandwiched between the partition plate 30 and the side facing the first housing 10. The portion of the first surface-shaped heat insulation pad 613 surrounding the first clearance hole 6131 and the second clearance hole is sealed to the partition plate 30, and a first air gap 615 is formed between the first surface-shaped heat insulation pad 613 and the partition plate 30.

[0091] The edge of the first surface heat insulation pad 613 in the first heat insulation pad 61 is clamped on the side of the partition 30 facing the first housing 10. This installation method not only stabilizes the position of the first surface heat insulation pad 613, but also ensures that the first surface heat insulation pad 613 fits tightly with the surrounding structure.

[0092] In addition, since the edge of the first heat insulation pad 613 is fixed to the partition plate 30, and the portion of the first heat insulation pad 613 surrounding the first clearance hole 6131 and the second clearance hole is sealed to the partition plate 30, a first air gap 615 is formed between the other areas of the first heat insulation pad 613 and the partition plate 30. This first air gap 615 is a relatively closed gas layer. Because the first air gap 615 is closed and the gas inside is stationary, the thermal conductivity of the first air gap 615 is much lower than that of solid materials. Therefore, the first air gap 615 becomes an effective heat insulation barrier.

[0093] Specifically, when the automotive horizontal rotary compressor 100 is running, the high-temperature, high-pressure refrigerant in the first chamber 11 attempts to transfer heat through the partition 30, but the presence of the first isolation air gap 615 slows down this process. It effectively prevents heat from being transferred from one side of the partition 30 to the other through direct contact, thereby maintaining the low-temperature environment in the second chamber 21 and ensuring the normal operation of the automotive horizontal rotary compressor 100.

[0094] According to some embodiments of the present invention, a horizontal rotary compressor 100 for vehicles, such as... Figure 4 As shown, the first heat insulation pad 61 includes a second surface heat insulation pad 614; the edge of the second surface heat insulation pad 614 is sandwiched between the partition plate 30 and the side facing the second housing 20, and the portion of the second surface heat insulation pad 614 surrounding the first clearance hole 6131 and the second clearance hole is sealed to the partition plate 30, and a second air gap 616 is formed between the second surface heat insulation pad 614 and the partition plate 30.

[0095] The second-face heat insulation pad 614 is similar to the first-face heat insulation pad 613. The edge of the second-face heat insulation pad 614 is securely clamped between the partition 30 and the second housing 20 to ensure its positional stability and sealing.

[0096] Similarly, the portion of the second-sided heat insulation pad 614 surrounding the first clearance hole 6131 and the second clearance hole is sealed to the partition plate 30. Then, the remaining areas of the second-sided heat insulation pad 614 form a second air gap 616 between itself and the partition plate 30. This second air gap 616 is formed by the space between the second-sided heat insulation pad 614 and the partition plate 30 where they are not in direct contact. This space is also sealed, forming a relatively closed gas layer. This second air gap 616 also utilizes the low thermal conductivity of the still air within it to block heat transfer.

[0097] By setting a second isolation air gap 616, the heat insulation performance of the vehicle horizontal rotary compressor 100 can be greatly improved, making it more difficult for heat to be transferred from the first chamber 11 to the second chamber 21.

[0098] According to some embodiments of the present invention, a vehicle-mounted horizontal rotary compressor 100, combined with... Figure 4 The compression mechanism 40 includes a main bearing 41, which includes a shaft tube section 411 located in the through hole 31.

[0099] Since the main bearing 41 is a key component supporting the crankshaft 50 in the automotive horizontal rotary compressor 100, it bears the radial and axial loads of the crankshaft 50. Therefore, a shaft tube section 411 is specially designed in the main bearing 41, which passes through the through hole 31 on the partition 30, serving as the support and guide part of the crankshaft 50 on the partition 30. The shaft tube section 411 ensures that the crankshaft 50 maintains a smooth trajectory when rotating at high speed, reducing mechanical stress caused by vibration and imbalance, thereby extending the service life of the automotive horizontal rotary compressor 100.

[0100] When the first heat insulation pad 61 includes a first surface heat insulation pad 613, the first surface heat insulation pad 613 connects to the outer peripheral surface of the shaft tube section 411.

[0101] This connection method not only enhances the structural strength between the first heat insulation pad 613 and the shaft tube section 411, but also achieves a tight seal between them. Even during the operation of the automotive horizontal rotary compressor 100, the high-pressure gas in the first chamber 11 is unlikely to leak out through the gap between the first heat insulation pad 613 and the partition 30.

[0102] When the first heat insulation pad 61 includes the second surface heat insulation pad 614, the second surface heat insulation pad 614 is connected to the outer peripheral surface of the shaft tube section 411.

[0103] This connection method enhances the structural strength between the second heat insulation pad 614 and the shaft tube section 411, and also ensures a tight seal between them. This prevents gas in the second chamber 21 from leaking out through the gap between the second heat insulation pad 614 and the partition 30 during operation of the automotive horizontal rotary compressor 100, thus avoiding insufficient air intake of the automotive horizontal rotary compressor 100.

[0104] In some alternative embodiments, the edge of the first heat insulation pad 61 is clamped to at least one side of the partition 30, and the edge of the first heat insulation pad 61 is provided with a first protrusion 616, which is located on the side of the first heat insulation pad 61 facing the partition 30 and / or away from the partition 30.

[0105] First, the first protrusions 616 serve a positioning function during installation. When the first heat insulation pad 61 is placed on the partition 30, these first protrusions 616 automatically align and embed into the predetermined installation position, thereby simplifying the installation steps and reducing installation errors. This efficient positioning design not only improves installation efficiency but also ensures a tight fit between the first heat insulation pad 61 and the partition 30, laying the foundation for the stable operation of the subsequent automotive horizontal rotary compressor 100.

[0106] Secondly, another function of the first protrusion 616 is to reduce gas leakage. Whether located on the side facing the partition 30 or the side away from the partition 30, these protrusions effectively prevent gas from seeping through the tiny gaps between the insulation pad 60 and the partition 30. When the first protrusion 616 faces the partition 30, it forms a physical barrier, reducing the possibility of external gas entering the first air gap 615. This reduces heat loss due to convection and conduction of gas inside the first air gap 615, helping to improve the insulation effect of the first insulation pad 61. Figure 4 - Figure 5 When the first protrusion 616 faces away from the partition 30, it also forms a physical barrier. At this time, the first protrusion 616 faces the first housing 10 or the second housing 20 to reduce gas flow between the first cavity 11 or the second cavity 21 and the outside. By reducing the gas flow between the first cavity 11, the second cavity 21 and the outside, the normal operation of the automotive horizontal rotary compressor 100 can be ensured, and the automotive horizontal rotary compressor 100 can operate reliably under various operating conditions.

[0107] In addition, the first protrusion 616 can also prevent external impurities or corrosive gases from entering the interior of the vehicle horizontal rotary compressor 100 to a certain extent, reducing the probability of impurities and corrosive gases entering the interior of the vehicle horizontal rotary compressor 100 and causing damage to the internal components, and protecting the cleanliness and dryness of the internal environment of the vehicle horizontal rotary compressor 100.

[0108] like Figure 5 As shown, according to some embodiments of the present invention, the vehicle horizontal rotary compressor 100 includes a compression mechanism 40 comprising a compression shell 42, the edge of which is sandwiched between a partition 30 and a first housing 10.

[0109] The compression housing 42 is one of the core components of the automotive horizontal rotary compressor 100. The compression housing 42 contains an important component of the compression mechanism 40, which is used to control the gas flow path and compression process.

[0110] The compression shell 42 provides a closed space for the compression process. At the same time, the compression shell 42 separates the first cavity 11 and the second cavity 21, thereby reducing the heat flow from the first cavity 11 to the second cavity 21.

[0111] The partition 30 is located on one side of the compression housing 42, closely fitting the edge of the compression housing 42, and together with the first housing 10, clamps and fixes the compression housing 42. The partition 30 not only separates the exhaust area, i.e., the first chamber 11, of the automotive horizontal rotary compressor 100, ensuring that the gas flows along a predetermined path, but also reduces the thermal impact of the high-temperature gas in the first chamber 11 on other parts of the automotive horizontal rotary compressor 100.

[0112] To further mitigate the thermal impact of the high-temperature gas inside the first cavity 11, such as Figure 5 As shown, the heat insulation pad 60 also includes a second heat insulation pad 62, which is sandwiched between the edge of the compression shell portion 42 and the second shell 20. The second heat insulation pad 62 forms an additional heat insulation barrier, the main function of which is to prevent the high-temperature gas in the first cavity 11 from having a thermal impact on the second shell 20 or other parts of the vehicle horizontal rotary compressor 100, thereby protecting the stability and durability of the overall structure of the vehicle horizontal rotary compressor 100.

[0113] In some alternative embodiments, the thermal conductivity of the material of the heat insulation pad 60 is λ1, and the thermal conductivity of the material of the compression shell 42 is λ4, where λ1≤λ4.

[0114] When the thermal conductivity λ1 of the insulation pad 60 is less than λ4, it can effectively block the heat transfer between the first shell 10 and the compression shell 42.

[0115] In some alternative embodiments, the second heat insulation pad 62 is provided with a second protrusion (not shown), which is located on the side of the second heat insulation pad 62 facing the compression shell portion 42 and / or on the side facing the first shell 10.

[0116] In the above embodiment, when the second protrusions are located on the side of the second heat insulation pad 62 facing the compression shell 42, they directly contact the edge of the compression shell 42.

[0117] First, the close contact between the second protrusion and the edge of the compression shell 42 reduces the gap between them, thereby reducing the possibility of gas leakage through these tiny gaps. This helps to effectively isolate the high-temperature, high-pressure gas inside the first cavity 11 from the external environment or adjacent cavities.

[0118] Secondly, the second protrusion forms an additional thermal barrier between the compression shell 42 and the second thermal insulation pad 62. By increasing and decreasing the heat conduction path, the second protrusion improves the thermal insulation performance of the second thermal insulation pad 62.

[0119] Furthermore, the second protrusion also serves a positioning function during installation. The second protrusion helps the second heat insulation pad 62 to be quickly and accurately aligned and secured to the edge of the compression housing 42. This simplifies the installation process and improves assembly efficiency.

[0120] When the second protrusions are located on the side of the second heat insulation pad 62 facing the first housing 10, they mainly face the first housing 10. The second protrusions can block the gap between the second heat insulation pad 62 and the first housing 10, thereby improving the sealing effect between the second heat insulation pad 62 and the first housing 10, reducing the gas flow channels between them, and improving the overall sealing performance of the automotive horizontal rotary compressor 100.

[0121] When the second protrusion is located on the side of the second heat insulation pad 62 facing the compression housing 42, the close contact between the second protrusion and the edge of the compression housing 42 improves the sealing performance between them. During the operation of the automotive horizontal rotary compressor 100, high-temperature and high-pressure gas is generated within the compression housing 42 and may attempt to leak to the outside or adjacent cavities through tiny gaps. The second protrusion effectively reduces the possibility of such leakage, ensuring that the gas flow path strictly follows the design.

[0122] According to some embodiments of the present invention, a horizontal rotary compressor 100 for vehicles, such as... Figure 6 As shown, the heat insulation pad 60 includes a heat insulation layer 601 and a sealing layer 602. By providing the heat insulation layer 601 and the sealing layer 602, the dual requirements of heat insulation and sealing of the automotive horizontal rotary compressor 100 under various operating conditions are met.

[0123] The heat insulation layer 601 is an elastic layer. This elastic layer has a certain degree of deformation capability, allowing it to adapt to the minor deformations of the components caused by the operation of the automotive horizontal rotary compressor 100. This adaptability helps maintain close contact between the heat insulation pad 60 and the various components of the automotive horizontal rotary compressor 100, thereby maintaining good heat insulation and sealing effects. Furthermore, the elastic layer can also absorb and disperse vibration energy to a certain extent, reducing noise and vibration during the operation of the automotive horizontal rotary compressor 100 and improving overall operational stability.

[0124] Alternatively, the elastic layer may be made of a high thermal resistance material, which helps to slow down heat transfer.

[0125] A sealing layer 602 is disposed on at least one side of the heat insulation layer 601. Optionally, the sealing layer 602 is a material layer with excellent sealing performance, such as a rubber layer or a silicone layer. By tightly adhering the sealing layer 602 to the surface of the components of the automotive horizontal rotary compressor 100, a reliable sealing barrier is formed to prevent gas leakage. Providing the sealing layer 602 on the heat insulation pad 60 can further improve the isolation effect between the internal chambers of the automotive horizontal rotary compressor 100, ensuring the stable operation of the automotive horizontal rotary compressor 100.

[0126] The sealing layer 602, located on either side of the insulation layer 601, can improve the sealing performance of the insulation pad 60. Combined with... Figure 6 The sealing layer 602 is located on both sides opposite to the heat insulation layer 601, which can further improve the sealing performance of both sides of the heat insulation pad 60.

[0127] According to some embodiments of the present invention, the vehicle horizontal rotary compressor 100 includes a heat insulation pad 60 comprising at least one of a steel layer, a rubber layer, and a plastic layer.

[0128] When the heat insulation pad 60 includes a steel layer, it enhances the structural strength and stability of the heat insulation pad 60. As a high-strength material, the steel layer can withstand various mechanical loads during the operation of the automotive horizontal rotary compressor 100, preventing the heat insulation pad 60 from deforming or being damaged due to compression or vibration. Furthermore, the steel layer also serves as the skeleton of the heat insulation pad 60, supporting other material layers and ensuring the integrity and stability of the entire heat insulation pad 60.

[0129] When the heat insulation pad 60 includes a rubber layer, it significantly improves elasticity and sealing performance. The rubber layer also possesses good flexibility and sealing properties, allowing it to closely conform to the surface of the automotive horizontal rotary compressor 100 components, forming an effective sealing barrier. Simultaneously, the rubber layer absorbs and disperses vibration energy, reducing noise and vibration during the operation of the automotive horizontal rotary compressor 100. Optionally, when the heat insulation pad 60 simultaneously includes a steel layer, a rubber layer, and a plastic layer, the rubber layer is located between the steel layer and the plastic layer, serving a connecting and buffering function.

[0130] When the heat insulation pad 60 includes a plastic layer, the plastic layer provides insulation and corrosion resistance. This is because plastic layers typically have good thermal resistance and corrosion resistance, effectively blocking heat transfer and preventing chemical corrosion. In the automotive horizontal rotary compressor 100, the plastic layer protects internal components from high temperatures and corrosive substances, extending their service life. Furthermore, the plastic layer possesses a certain degree of hardness and wear resistance, resisting abrasion and damage from the external environment.

[0131] According to a second aspect embodiment of the present invention, an air conditioning system 200 is described, with reference to... Figure 7 This includes the vehicle horizontal rotary compressor 100 according to the first aspect embodiment of the present invention. This improves the energy efficiency of the air conditioning system 200.

[0132] It is worth noting that the type of air conditioning system 200 in this application embodiment is not limited, and it can be an integrated air conditioning unit or a split air conditioning unit.

[0133] According to a third aspect embodiment of the present utility model, the vehicle 1000, with reference to... Figure 7 This includes the air conditioning system 200 of the second aspect embodiment of this application or the vehicle horizontal rotary compressor 100 of the first aspect embodiment.

It is worth noting that the specific type of vehicle referred to in this utility model is not limited. For example, the vehicle can be a fuel vehicle, a gas vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, range-extended electric vehicles, solar electric vehicles, gas fuel vehicles such as hydrogen engine vehicles, or biofuel vehicles such as vehicles powered by ethanol, biodiesel, etc.

[0134] By integrating the vehicle horizontal rotary compressor 100 according to the first aspect embodiment of the present invention, the performance of the air conditioning system 200 in the vehicle 1000 can be improved, and the reliability of the vehicle 1000 can be enhanced.
