Description

Technical Field

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

[0002] Currently, more and more vehicle air conditioning systems have put forward requirements for low-temperature heating. Therefore, the minimum evaporation temperature at which the compressor operates has been continuously decreasing, and the superheat degree has been continuously decreasing. However, a lower evaporation temperature will lead to a decrease in suction superheat. When sucking in, a large amount of refrigerant presents a liquid state, and there is a risk of liquid slugging.

[0003] Patent CN117703761A proposes a horizontal scroll compressor oil baffle structure and a horizontal scroll compressor. A bearing component is provided inside the housing of the horizontal scroll compressor. There is an exhaust port above the compressor exhaust cavity. A second partition plate and a first partition plate are near the exhaust port. The second partition plate has a first exhaust hole and a first central convex cylinder. The first central convex cylinder is sleeved on the bearing component. The first partition plate has a second exhaust hole and a first central through hole. The bearing component passes through the first central through hole. A sealed separation cavity is formed between the second partition plate and the first partition plate. The oil-gas mixed airflow inside the housing enters the separation cavity through the first exhaust hole for gas-liquid separation and is discharged through the second exhaust hole. The utility model can control the oil level in the oil storage chamber inside the compressor, avoid the disturbance of the oil level inside the compressor, effectively improve the oil-gas separation efficiency, avoid excessive refrigerant oil from entering the air conditioning system, ensure the heat exchange effect and energy efficiency of the air conditioning system, and effectively ensure the reliability and operating energy efficiency of the compressor.

[0004] Patent CN221236899U provides an oil-gas separator and a scroll air compressor having the same. The oil-gas separator is provided with a through oil pipe, and the through oil pipe can lead out the liquid after gas-liquid separation from the oil-gas separator. Among them: the oil-gas separator includes a water removal unit; the water removal unit is arranged on the through oil pipe and / or the water removal unit is arranged inside the oil-gas separator; the water removal unit includes a water removal medium, and the water removal medium can allow oil to pass through the water removal unit, and the water removal medium can adsorb water in the liquid. The utility model makes the water content of the lubricating oil separated by the oil-gas separator greatly reduced, and even expected to be completely dried after being dried by the water removal unit by arranging the water removal unit on the through oil pipe and / or inside the oil-gas separator. Thus, the lubricating oil passing through the oil-gas separator has a better lubricating effect during use, can avoid the problem of performance degradation of the lubricating oil caused by the water content of the lubricating oil, and makes the lubricating oil have better lubricating performance.

[0005] The above two patents are for the gas separation structure design of the compressor exhaust. They both perform gas-liquid separation on the refrigerant entering the air-conditioning system to ensure the refrigeration effect of the entire system, and also perform drying treatment on the exhaust to reduce the water content in the system. However, they do not further consider the liquid hammer problem during low-temperature heating. Considering that the compressor operates at a lower evaporation temperature when it is a low-temperature heat pump, when the suction superheat is insufficient, a large amount of liquid refrigerant will enter the compressor, posing a risk of liquid hammer.

[0006] In view of this, the present utility model provides a horizontal compressor and a new energy vehicle. Summary of the Utility Model

[0084] Figure 7 It is a partial exploded view of the second horizontal compressor of the present utility model. Refer to Figure 7 As shown, the difference between the second horizontal compressor and the first horizontal compressor of the present utility model is that the rear housing 6 and the baffle 5 are separated from each other. Specifically, the baffle 5 is a part independent of the rear housing 6. The baffle 5 and the controller housing enclose the first chamber 4, and the baffle 5 and the rear housing 6 enclose the second chamber 9. The baffle 5 is fixed by bolts. The rest of the related technical features and technical effects are as described above and will not be elaborated here.

[0085] The utility model relates to an electric compressor suitable for R290 refrigerant. By using the designed compressor structure, on the basis that the compressor can meet the modular design and the suction port orientation can be adjusted arbitrarily, through the designed intake structure, after the compressor completes suction, it can carry out gas-liquid separation through the self-contained gas-liquid separator structure, ensuring that gaseous refrigerant enters the inside of the scroll when the scroll sucks air, and the liquid refrigerant is vaporized through the baffle structure, reducing the risk of liquid slugging and ensuring the reliability during its operation.

[0086] Figure 5 and Figure 6 are schematic diagrams of the refrigerant flow direction of the first horizontal compressor of the present utility model. The following is combined with the specification appendix Figures 1 to 6 to introduce the specific implementation manners of the horizontal compressor of the present utility model:

[0087] This patent proposes a vehicle compressor adapted to low-temperature heating conditions, which is composed of a rear cover shell 1, a controller housing 3, a rear shell 6, a middle shell 10, a stationary disk 8, a front shell 11, etc. Among them, a secondary bearing seat 35, a suction port 31, a suction channel 32, a first suction through hole 33, a terminal post 34, a connecting bolt hole 36, and a gas baffle 395 are arranged on the controller housing 3. The suction port can be located at any position in the 360° circumferential direction. Figure 4 The figure in the middle is a schematic diagram arranged directly below. The system intake enters the suction channel 32 through the suction port 31. The suction channel 32 is a passage independent of the low-pressure chamber of the compressor and is communicated with the first chamber 4 (low-pressure chamber) through the first suction through hole 33. When the compressor operates, the mixture of refrigerant and lubricating oil enters the inside of the first chamber 4 of the compressor via the suction port 31 → suction channel 32 → first suction through hole 33 and collides with the gas baffle. The oil and liquid refrigerant deposit downward under the action of gravity. At the same time, the liquid refrigerant is continuously vaporized during this process, reducing the content of liquid refrigerant. Specifically, the liquid refrigerant in the oil and refrigerant mixture entering the first chamber 4 from the first suction through hole 33 first falls into the oil sump under the action of gravity in the first separation cavity 391. The remaining mixture bypasses the diversion side wall 39 and reaches the second separation cavity 394, then collides with the gas baffle 395 for gas-liquid separation, and the separated liquid refrigerant falls into the oil sump again under the action of gravity. The position of the first suction through hole 33 is higher than the liquid level of the oil sump inside the compressor, ensuring that the lubricating oil will not flow out through the suction port during the installation, use, and disassembly of the compressor, so as to ensure the oil storage inside the compressor and the convenience during assembly.

[0088] Figure 3It is a schematic diagram of the rear housing, which includes a baffle 5, a bearing through-hole 51, a terminal through-hole 52, a second suction through-hole 55, a bolt through-hole 54 and an oil passage, and there is an oil passage filter screen 53 on its oil passage. Among them, the terminal through-hole 52 and the bearing through-hole 51 are respectively used to pass through the terminal 34 structure on the controller housing and the auxiliary bearing seat 35, and are connected to the front-side crankshaft, motor, etc.; the bolt through-hole 54 on it is used to install bolts connecting the rear housing 6 and the controller housing 3; the baffle 5 at the bottom is used to separate the first chamber 4 and the second chamber 9 after being assembled with the controller housing. The oil passage is opened at the bottom oil sump, communicating the first chamber 4 and the second chamber 9, and filtering impurities through the oil passage filter screen 53. The second suction through-hole 55 can be higher than the liquid level, and the gaseous refrigerant enters the second chamber 9 from the first chamber 4 through the second suction through-hole 55. Its position is located at the far end away from the first suction through-hole 33, specifically located in Figure 3 the symmetric included angle of 90° formed by the first quadrant and the fourth quadrant in Figure 3 , but not limited thereto.

[0089] The compressor proposed in this patent, such as Figure 5 , 6 shown, after the refrigerant fluid enters the suction port 31, it enters the first chamber 4 through the first suction through-hole 33. The first chamber 4 is formed after the connection of the controller housing 3 and the rear housing 6. Its bottom is the controller housing 3, and the top is the baffle 5 structure on the rear housing 6. The mixture of refrigerant and lubricating oil hits the top baffle 5 after passing through the first suction through-hole 33, changes the flow direction, and flows around the auxiliary bearing seat 35 in the first chamber 4. There is a gas baffle 395 arranged in the first chamber 4, and the airflow hits the gas baffle 395 again during the flow process to separate the gas-liquid two phases. The first chamber 4 is connected to the external suction channel through the first suction through-hole 33, and the first chamber 4 is also connected to the second chamber 9 through the second suction through-hole 55 and the oil passage respectively. The separated oil enters the second chamber 9 through the oil passage and is filtered by the oil passage filter screen 53 to block impurities. The gaseous refrigerant enters the second chamber 9 through the second suction through-hole 55, and the liquid refrigerant vaporizes when flowing through the gas baffle, reducing the risk of liquid hammer. The utility model can effectively separate the gaseous refrigerant and the liquid refrigerant after suction, reduce the risk of liquid hammer, and enhance the reliability of the compressor operation.

[0090] The utility model also provides a new energy vehicle adopting the above horizontal compressor. Through the structural design, the utility model can make the direction of the suction port 31 not be restricted too much. The suction port 31 facing any direction does not affect the operation of the compressor, further relaxing the layout conditions of the compressor in the system, especially being beneficial to the layout in the new energy vehicle with a narrow space. The rest of the relevant technical features and technical effects are as described above and will not be elaborated here.

[0091] In summary, the horizontal compressor and the new energy vehicle of the present utility model enable the compressor to separate gaseous refrigerant and liquid refrigerant through gas-liquid separation after suction, and fully separate gas phase and liquid phase through the baffle structure, realizing the gas-liquid separation function, reducing the risk of liquid hammer, and enhancing the reliability of the compressor operation.

[0092] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope of the present utility model.
