Description

Technical Field

[0001] The utility model relates to the field of vehicle-mounted refrigeration equipment, and 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] Furthermore, when the compressor is running at high speed, the high-speed gas after oil and gas separation on the exhaust side will flow along the interior of the front shell and impact the liquid surface of the oil pool at the bottom, causing the separated gaseous refrigerant to mix with the liquid lubricating oil, thus failing to achieve the ideal separation effect. This results in the gaseous refrigerant still containing a large amount of refrigeration oil, and the refrigeration oil is not fully returned to the intended area.

[0005] In view of this, the utility model provides a horizontal compressor and a new energy vehicle. Utility Model Content

[0060] In a preferred embodiment, the oil-gas separation cover 3 and the static vortex 5 are combined to form an oil expansion chamber 54 connected to the exhaust hole 51.

[0065] The following is in conjunction with the instructions Figures 1 to 5 To introduce the specific implementation of the horizontal compressor of the utility model:

[0066] Continue to refer Figures 1 to 5(In order to clearly see the oil-gas separation cover 3 inside the compressor, the front shell is omitted in the drawing). The utility model provides a horizontal scroll compressor, including a cavity formed by a middle shell 1 and a rear shell 2, and an oil-gas separation cover 3. The cavity accommodates a motor 4, a movable scroll, and a static scroll 5. The static scroll 5 is provided with an exhaust hole 51 and an oil return port 52 on the first side facing away from the cavity. The oil-gas separation cover 3 is covered by the front shell and connected to the first side of the static scroll 5. A high-pressure chamber is formed between the front shell and the static scroll. The high-pressure chamber is provided with an exhaust port connected to the outside. The oil-gas separation cover 3 includes an oil-gas separation chamber 30 with a core rod, a horizontal baffle 33 and a vertical baffle 34. The horizontal baffle 33 covers the bottom oil pool and is distributed with a number of through holes 331. The oil-gas separation chamber 30 has a refrigerant outlet 32 ​​for exhausting upwards. The vertical baffle 34 is provided on the upper surface of the horizontal baffle 33 and separates the exhaust hole from the refrigerant outlet 32 ​​in the high-pressure chamber. The oil-gas separation chamber 30 is axially perpendicular to the horizontal baffle 33, and the plane of the vertical baffle 34 is perpendicular to the plane of the fixed scroll 5. The vertical baffle 34 divides the horizontal baffle 33 into a first side and a second side. The oil-gas separation chamber 30, the notch 332, and the through-hole 331 are located on the first side of the horizontal baffle 33, with the exhaust port facing the second side of the horizontal baffle 33. The cross-sectional area of ​​the exhaust port 51 is less than or equal to the sum of the cross-sectional areas of the rectifying channel 31, which is less than the sum of the cross-sectional areas of the notch 332 and the through-hole 331. The sum of the cross-sectional areas of the notch 332 and the through-hole 331 is less than or equal to the cross-sectional area of ​​the exhaust port. The oil-gas separation cover 3 and the fixed scroll 5 together form an oil expansion chamber 54 that connects 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 that connects the oil expansion chamber 54 to the oil-gas separation chamber 30.

[0067] In this utility model, a combination of horizontal baffles 33 and vertical baffles 34 prevents gaseous refrigerant from impacting the liquid surface. The horizontal baffles 33 are arranged horizontally, while the vertical baffles 34 are arranged vertically and close to the compressor exhaust port. The horizontal baffles 33 are designed to prevent excessive refrigerant flow from blowing against the refrigerant oil surface, causing the liquid surface to become unstable and leading to remixing of the oil and gas. The vertical baffles 34 are designed to prevent a small amount of refrigerant oil carried over by the refrigerant from being discharged from the compressor exhaust port along with the refrigerant. Figure 5 The gaseous refrigerant discharged from the refrigerant outlet 32 ​​diffuses along the inner wall of the front housing and is mostly blocked by the vertical baffle 34, thus preventing a small amount of refrigeration oil carried along with the refrigerant from being directly discharged from the compressor exhaust port. After being blocked, the lubricating oil (refrigeration oil) carried along by the refrigerant passes through the through hole 331 and the notch 332 in the horizontal baffle 33 and the flow channel formed by the inner wall of the front housing, and drips into the oil pool at the bottom.

[0068] 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.

[0069] 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.

[0070] In summary, the horizontal compressor and new energy vehicles of the present invention can use the transversely arranged baffles to avoid the refrigeration oil liquid surface from being blown due to excessive refrigerant flow rate, resulting in liquid surface instability and causing oil and gas to mix again; the longitudinally arranged baffles are used to prevent a small amount of refrigeration oil brought out by the refrigerant from being discharged from the compressor exhaust port together with the refrigerant, effectively preventing problems such as liquid surface instability, oil and gas remixing, and refrigeration oil being discharged with the refrigerant, thereby ensuring the quality of oil and gas separation.

[0071] 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.
