Description

Technical Field

[0001] The utility model relates to the field of vehicle-mounted refrigeration equipment, specifically, to a horizontal compressor and a new energy vehicle. Background Art

[0002] Scroll compressors require sufficient oil to lubricate key components such as the rotating and stationary scrolls and bearings. Typically, the lubricating oil is discharged from the compressor along with the refrigerant. Maximizing oil-gas separation and maximizing oil storage space are crucial for compressor reliability. Furthermore, compressors generate noise during operation, typically originating from compressor gas noise, scroll meshing, and valve plate vibration. Therefore, equipping the compressor's exhaust side with a silencer is commonplace.

[0003] Existing scroll compressors usually use a centrifugal rotating oil-gas separation structure, which has a poor oil-gas separation effect and no obvious silencing or noise reduction function. At the same time, the oil storage tank space is limited to the internal space of the high-pressure cover, and the oil storage space is small, resulting in poor oil return effect of the compressor and greatly reduced reliability.

[0004] Patent CN115370572A provides an oil separation hood and a scroll compressor. The oil separation hood is used for oil and gas separation in a scroll compressor and includes a base and a hood body connected to the base. The hood body is provided with an air inlet chamber that can be connected to the exhaust port of the static scroll of the compressor, an oil separation structure, and an oil pool that can be connected to the oil storage chamber of the front shell of the scroll compressor. The oil separation structure includes a channel housing provided with an oil and gas passage, an air inlet, an oil outlet passage, and a first exhaust port. The air inlet connects the air inlet chamber and the oil and gas passage. The oil outlet passage is provided in the channel housing and has an oil inlet hole that connects the oil and gas passage and the oil pool. The first exhaust port is provided at the other end of the channel housing and can be connected to the exhaust port of the scroll compressor. The oil separation hood of the utility model is provided with an oil separation structure and an oil pool, which greatly increases the oil storage space of the compressor, allowing the entire compressor to obtain better oil return and lubrication. At the same time, the oil separation hood is designed with a noise reduction and vibration reduction structure, which effectively reduces the exhaust noise of the compressor. However, this structure is difficult to meet the oil return requirements. At high speeds and high oil circulation rates, the oil-air mixture tumbles disorderly on the compressor's exhaust side, making it impossible to accurately measure the oil level on the compressor's front housing, which means poor oil return. Consequently, the lubrication and sealing of the orbiting and static scrolls cannot be effectively achieved, and the overall temperature rise of the compressor cannot be effectively controlled, resulting in poor heat dissipation and a shortened compressor lifespan.

[0005] Patent CN215633776U provides an oil-gas separator, a compressor and an air conditioner. The compressor includes a static scroll exhaust port. The oil-gas separator includes a cover body. An air inlet cavity is provided in the cover body. The air inlet cavity is connected to the static scroll exhaust port. At least one oil-gas separation channel is also provided in the cover body. One end of each oil separation channel in the oil-gas separation channel is connected to the air inlet cavity, and the other end is connected to the outside of the cover body. At least one oil return channel is also provided in the cover body. The oil return channel is constructed to discharge the lubricating oil in the oil-gas separation channel and / or the air inlet cavity. The oil-gas separator disclosed in the present invention is used for oil and gas separation of a scroll compressor. A plurality of oil-gas separation channels and oil return channels are provided in the cover body. The oil-gas separation channel has an oil-gas separation function, which reduces the amount of lubricating oil discharged, improves the reliability of the compressor, enhances the heat exchange performance of the compressor and the energy efficiency of the entire machine, reduces exhaust noise, and reduces the temperature of high-temperature refrigerant gas. However, the oil-gas separator structure is complex and expensive, with multiple oil-gas separation channels, oil return channels, and various internal structures (such as rotating oil baffles and a labyrinth structure). This structure also occupies a large space, which may impose certain limitations on the overall structural design of the compressor.

[0006] In the above structure, the scroll compressor has the following disadvantages:

[0007] (1) The oil-gas separation effect on the exhaust side is poor. During the operation of the compressor, the oil-gas separation link on the exhaust side has obvious defects and fails to achieve the ideal separation effect. Specifically, when the oil-gas mixture passes through the exhaust side, the gaseous refrigerant and the refrigeration oil cannot be effectively separated. This results in the gaseous refrigerant still containing a large amount of refrigeration oil, and the refrigeration oil cannot be completely returned to the area where it should be.

[0008] (2) Poor oil return performance at high compressor speeds and high oil circulation rates (OCR). Poor oil return performance becomes a prominent issue when the compressor is operating at high speeds and high oil circulation rates. Under these high-load operating conditions, the flow rate of the oil-air mixture inside the compressor increases, and the interaction between the oil and air becomes more complex.

[0009] (3) The existing design structure is complex and the cost is high. The current compressor oil separation design is too complex in structure.

[0010] In view of this, the utility model provides a horizontal compressor and a new energy vehicle. Utility Model Content

[0074] In a preferred embodiment, a horizontal baffle with through holes is also included, but the present invention is not limited thereto.

[0075] The following is in conjunction with the instructions Figures 1 to 7 To introduce the specific implementation of the horizontal compressor of the utility model:

[0076] Continue to refer Figures 1 to 7(The front housing is omitted in the drawings to clearly show the oil-gas separation cover 3 inside the compressor.) The present invention provides a horizontal scroll compressor in which a center housing 1 and a rear housing 2 together form a cavity that accommodates a motor 4, an orbiting scroll, a stationary scroll 5, and an oil-gas separation cover 3. A high-pressure chamber is formed between the front housing and the stationary scroll 5. The high-pressure chamber is equipped with an exhaust port connected to the outside. An exhaust port 51 and an oil return port 52 are provided on the first side of the stationary scroll 5, facing away from the cavity. The oil-gas separation cover 3 is covered by the front housing and connected to the first side of the fixed scroll 5. The oil-gas separation cover 3 includes an oil-gas separation chamber 30 with a core rod 35. A tubular first separation chamber 351 is formed between the outer wall of the core rod 35 and the inner wall of the oil-gas separation chamber 30. The oil-gas separation cover 3 and the fixed scroll 5 together form an oil expansion chamber 54 connected to the exhaust port 51. The oil-gas separation cover 3 has a raised oblique boss on the side facing the fixed scroll 5. Within this boss is at least one rectifying channel 31 connecting the oil expansion chamber 54 and the first separation chamber 351. The rectifying channel 31 extends tangentially to the annular flow passage within which the first separation chamber 351 is located. Furthermore, the first horizontal projection of the first separation chamber 351 and the second horizontal projection of the rectifying channel 31 do not overlap, ensuring that the rectifying channels do not interfere with the core rod in terms of projection. The three rectifying channels 31 are arranged vertically in the top, middle, and bottom directions, and extend parallel to each other. The cross-sectional area of ​​the exhaust hole 51 is less than or equal to the total cross-sectional area of ​​the rectifying channel 31, and the total cross-sectional area of ​​the rectifying channel 31 is less than or equal to the cross-sectional area of ​​the exhaust port, thereby effectively preventing throttling during the flow of oil and gas. The inner wall of the core rod 35 encloses a second separation chamber 352, which is a rod-shaped separation chamber. High-pressure gas entering the oil expansion chamber 54 from the exhaust hole 51 expands, passes through the rectifying channel 31, and enters the first separation chamber 351. The gaseous refrigerant rotates and separates along the first separation chamber 351, flows downward, then passes over the end of the core rod 35 and upward into the second separation chamber 352. It then enters the high-pressure chamber and is discharged through the exhaust hole. The bottom of the first separation chamber 351 converges inward to form a funnel structure. A first oil outlet 361 is located at the bottom of the funnel structure, connecting to the inverted L-shaped oil outlet pipeline 36. The oil outlet 367 of the inverted L-shaped oil outlet pipeline 36 is at a greater height than the first oil outlet 361, but this is not a limitation. The refrigerant lubricating oil generated during the separation process flows downward, driven by gravity and pressure differential, along the sidewalls of the first and second separation chambers 351, 352. It then flows through the L-shaped oil outlet line 36 and into the compressor oil sump, which is then connected to the oil return port 52. An oil drain port 368 is provided at the bottom of the oil separation expansion chamber 54, connecting to the L-shaped oil outlet line 36. The L-shaped oil outlet line 36 not only serves as an oil outlet channel but also serves to block bubbles generated during the oil separation process, preventing them from flowing downward and impacting the stable oil sump within the front housing.

[0077] During operation of the system of the present invention, the compressed, high-temperature, high-pressure oil-gas mixture is discharged from the exhaust port 51 of the fixed scroll 5 and then enters the oil expansion chamber 54 enclosed by the oil-gas separation cover 3 and the fixed scroll 5. Here, a small portion of the oil-gas mixture escapes through a small opening below the oil expansion chamber 54, while the remaining oil-gas mixture is directed into three inclined rectification channels 31 for rectification before entering the oil-gas separation chamber 30 for oil-gas separation.

[0078] As the oil-gas mixture rotates at high speed around the core rod 35, the dense refrigeration oil, under the influence of gravity, flows downward along the side walls of the first and second separation chambers 351 and 352, passes through the inverted L-shaped oil outlet pipe 36, and flows into the compressor oil pool (the refrigeration oil area below the front shell). The compressor oil pool is connected to the oil return port 52. Due to the pressure difference, the oil is sucked into the low-pressure side through the oil return hole.

[0079] Since the density of the gaseous refrigerant is lower than that of the refrigerant oil, it flows in the opposite direction to the refrigerant oil. After lifting the valve plate 53, the gaseous refrigerant rotates and separates along the first separation chamber 351, then flows downward over the end of the core rod 35, upward into the second separation chamber 352, and then into the high-pressure chamber. Ultimately, it is above the refrigerant oil level and flows out of the compressor (discharged through the exhaust port). However, during this process, a small amount of refrigerant oil will still be carried out of the core rod by the gaseous refrigerant, similarly through the openings in the horizontal baffle, and eventually flow into the refrigerant oil area.

[0080] During operation, the compressor of the present invention displays a clearly discernible oil level, regardless of whether it is operating at high or low speeds, or at high or low oil circulation rates. Compared to previous oil separation structures, the current structure exhibits significantly reduced oil level fluctuations. Specifically, the oil distribution and flow conditions within the compressor are effectively optimized under different combinations of speeds and oil circulation rates. At high speeds, despite the accelerated flow and more complex interactions of the oil-air mixture, the new structural design ensures a relatively stable and clearly measurable oil level. At low speeds, where the oil flow is relatively smooth, the new structure also effectively suppresses potential oil level fluctuations. Across different oil circulation rates, whether rapidly circulating large quantities of oil at high circulation rates or relatively slow flowing oil at low circulation rates, the compressor maintains a clear oil level display with minimal fluctuations. This stable oil level provides strong support for accurate oil quantity monitoring and effective oil return control. Excellent oil level stability directly contributes to excellent oil return performance. The new structure precisely guides oil back to the designated location, reducing oil retention and loss in the system. The optimized oil return path and improved oil return efficiency significantly enhance the lubrication inside the compressor, effectively reducing wear and friction between components, thereby improving the overall performance and reliability of the compressor.

[0081] The present invention also provides a new energy vehicle utilizing the aforementioned horizontal compressor. The remaining relevant technical features and effects are as previously described and will not be elaborated upon here. This invention contributes to improving the overall NVH (Noise, Vibration, and Harshness) of new energy vehicles. This is a comprehensive measure of vehicle manufacturing quality that is most directly and superficially perceived by vehicle users.

[0082] In summary, the horizontal compressor and new energy vehicles of the present invention can achieve efficient and precise oil and gas separation, ensuring that the refrigeration oil and gaseous refrigerant can flow in an orderly manner, thereby improving the efficiency and stability of the system operation; the reasonable coordination of the rectification channel and the oil and gas separation area and the design without interference with the core rod optimize the oil and gas flow path and improve the separation efficiency; the scientific matching of the flow areas of each component effectively prevents throttling, ensures the smoothness of the oil and gas flow, and thus improves the system performance.

[0083] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
