Description

Technical Field

[0001] This utility model relates to the field of compressors, and in particular to a compressor, an air conditioner, and a vehicle. Background Technology

[0002] Compressors are typically equipped with pressure relief valves to prevent bursting failure due to excessive internal pressure, especially in single-stage or two-stage compressors handling high operating pressures such as CO2. When the discharge pressure is too high, the compressor often experiences excessively high discharge temperatures. To ensure the pressure relief valve functions effectively, a good seal must be maintained between the valve and the compressor housing.

[0003] In related technologies, when a compressor operates in a high-temperature environment (e.g., above 150 degrees Celsius), the tightening torque of the pressure relief valve generally decreases. This is because the pressure relief valve end face and housing surface undergo yielding deformation under high temperature and pressure, leading to a decrease in the valve torque and consequently, leakage from the housing surface. The compressor operates at high pressure, resulting in correspondingly high pressure on the housing surface. When this pressure exceeds the yield strength of the sealing material, especially under high-temperature conditions where the yield strength is significantly reduced and thermal expansion and contraction are intensified, yielding deformation is likely to occur. Once yielding deformation occurs, when the compressor stops or the ambient temperature drops, the material contraction causes a sharp drop in the housing surface pressure, resulting in refrigerant leakage from the housing surface. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide a compressor. According to this invention, the compressor achieves effective sealing between the pressure relief valve body and the housing by setting an inclined and elastic sealing element, while maintaining stability under high temperature and high pressure environments, effectively preventing leakage, and achieving a safe and reliable pressure relief function.

[0005] This utility model also proposes an air conditioner having the above-mentioned compressor.

[0006] This utility model also proposes a vehicle having the above-mentioned air conditioner.

[0007] The compressor according to this utility model includes: a housing, wherein a high-pressure chamber is formed inside the housing, and a pressure relief valve mounting hole is formed on the outer wall of the housing, wherein a pressure relief channel is provided on the bottom wall of the pressure relief valve mounting hole to connect the pressure relief valve mounting hole and the high-pressure chamber; a pressure relief valve assembly, wherein the pressure relief valve assembly is disposed in the pressure relief valve mounting hole of the housing, and the pressure relief valve assembly includes: a pressure relief valve body, wherein a pressure relief port is formed at one end of the pressure relief valve body, the pressure relief port being adapted to connect to the pressure relief channel; and a sealing element, wherein the sealing element is disposed at the end of the pressure relief valve body, the sealing element being constructed as an elastic element and the sealing element being at least partially inclined relative to the end face of the pressure relief valve body in a direction radially away from the pressure relief port.

[0008] According to the compressor of this utility model, by constructing the seal as an elastic element and at least partially inclined relative to the end face of the pressure relief valve body in a direction radially away from the pressure relief port, the seal can deform under the pressure of the pressure relief valve body end face during the process of setting the pressure relief valve assembly in the pressure relief valve mounting hole of the housing. This not only ensures tight contact between the seal and the housing and the end face of the pressure relief valve body, but also allows the seal to resist pressure using its elastic restoring force when subjected to high-pressure gas impact, preventing leakage and improving sealing performance. When the compressor temperature rises, the seal absorbs the energy of the increased housing surface pressure due to the thermal expansion effect, thereby preventing the housing surface pressure from rising further and avoiding yielding of the sealing material. When the compressor cools down, the seal can return to its original shape and maintain the initial housing surface pressure. In addition, if the housing surface yields due to high temperature and high pressure, the seal also has a certain compensation function, which can make up for a certain amount of yielding and prevent leakage caused by a sharp drop in housing surface pressure, ensuring the stability and sealing performance of the pressure relief valve assembly in high-temperature environments.

[0009] According to some embodiments of the present invention, the sealing element is at least partially inclined at its end face away from the pressure relief valve body in a direction radially away from the pressure relief port.

[0010] According to some embodiments of the present invention, the sealing element is constructed as a conical ring and has a through hole that avoids the pressure relief port.

[0011] According to some embodiments of the present invention, a protrusion is formed at one end of the pressure relief valve body, the pressure relief port is provided on the protrusion, and the sealing element is sleeved on the outer periphery of the protrusion.

[0012] According to some embodiments of this utility model, the thickness of the sealing element is h and satisfies: 0.2mm≤h≤2mm.

[0013] According to some embodiments of the present invention, the sealing element includes: a base portion, the base portion being configured as a conical ring; and a flexible element disposed on at least a portion of the outer surface of the base portion; wherein the base portion is configured as a metal element.

[0014] According to some embodiments of the present invention, the outer periphery of the pressure relief valve body is formed with an external thread, and the mounting hole of the pressure relief valve is formed with an internal thread that mates with the external thread.

[0015] According to some embodiments of the present invention, the pressure relief valve body includes: a mating section, the outer periphery of which is formed with the external thread; a sealing section, which is connected to one end of the mating section, at least a portion of which is configured such that its diameter gradually decreases in the direction away from the mating section, and the end of the sealing section is provided with the pressure relief port and abuts against the sealing element.

[0016] According to some embodiments of the present invention, the pressure relief valve body further includes: a mounting section, which is disposed at the other end of the mating section and is constructed as a regular polygon and / or a polygonal mounting hole is formed on the end face of the mounting section.

[0017] According to some embodiments of the present invention, the sealing element abuts against the bottom wall of the pressure relief valve mounting hole and the end of the pressure relief valve body on both sides in the thickness direction, respectively.

[0018] According to some embodiments of this utility model, the compressor uses CO2 refrigerant.

[0019] In summary, the compressor according to this utility model embodiment, by tilting the seal between the housing and the end face of the pressure relief valve body, allows the seal to deform under pressure from the housing and the end face of the pressure relief valve body during the installation of the pressure relief valve assembly in the pressure relief valve mounting hole of the housing. This not only ensures tight contact between the seal and the housing and the end face of the pressure relief valve body, but also allows the seal to resist pressure using its elastic restoring force when subjected to high-pressure gas impact, preventing leakage and improving sealing performance. Constructing the seal as a conical ring with a through-hole to avoid the pressure relief port facilitates the deformation of the seal between the housing and the end face of the pressure relief valve body, providing a better sealing effect because the conical ring can more effectively adapt to and fill the gap between the housing and the pressure relief valve body. The through-hole avoids the pressure relief port on the pressure relief valve body, allowing the pressure relief port to connect with the pressure relief channel, so that high-pressure gas inside the housing can flow out through the pressure relief port and the through-hole, thereby achieving the purpose of pressure relief. The protrusion formed at one end of the pressure relief valve body facilitates the setting of the pressure relief port and the installation of the seal on the protrusion. A pressure relief port is provided on the protrusion, and a seal is fitted around the outer circumference of the protrusion. The seal is installed by fitting around the outer circumference of the protrusion, which is convenient and reliable, and ensures good contact and sealing between the seal and the protrusion, thereby preventing gas leakage from the gap between the pressure relief valve body and the housing.

[0036] 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.

[0037] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship shown in the accompanying drawings, 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 with "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.

[0038] 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.

[0039] In related technologies, when a compressor operates in a high-temperature environment (e.g., above 150 degrees Celsius), the tightening torque of the pressure relief valve generally decreases. This is because the sealing face of the pressure relief valve and the housing undergoes yielding deformation under high temperature and pressure, leading to a decrease in the valve torque and consequently, leakage at the sealing face. The compressor operates at high pressure, resulting in correspondingly high sealing face pressure. When this pressure exceeds the yield strength of the sealing material, especially under high-temperature conditions where the yield strength is significantly reduced and thermal expansion and contraction are intensified, yielding deformation is likely to occur. Once yielding deformation occurs, when the compressor stops or the ambient temperature drops, the material contraction causes a sharp drop in the sealing face contact pressure, resulting in refrigerant leakage from the sealing face inside the compressor.

[0040] The following is for reference. Figures 1-4 The compressor 1 according to an embodiment of the present utility model is described.

[0041] like Figures 1-4As shown, the compressor 1 according to this utility model includes a housing 12 and a pressure relief valve assembly 11. A high-pressure chamber is formed inside the housing 12, and a pressure relief valve mounting hole 121 is formed on the outer wall of the housing 12. A pressure relief channel is provided on the bottom wall of the pressure relief valve mounting hole 121 to connect the pressure relief valve mounting hole 121 with the high-pressure chamber. The pressure relief valve assembly 11 is disposed in the pressure relief valve mounting hole 121 of the housing 12 to realize the pressure relief function and can release the excessive pressure in the housing 12 when needed.

[0042] The pressure relief valve assembly 11 includes a pressure relief valve body 111, one end of which has a pressure relief port adapted to connect to a pressure relief channel formed within a pressure relief valve mounting hole 121. The pressure relief channel communicates with a high-pressure chamber within the housing 12. Excessive pressure within the housing 12 can be released by venting gas outwards through the pressure relief channel. The pressure relief valve body 111 is connected to the pressure relief channel via the pressure relief port, allowing high-pressure gas within the housing 12 to flow out through the pressure relief port, thereby reducing the pressure within the housing 12.

[0043] The pressure relief valve assembly 11 also includes a seal 112, which works in conjunction with the pressure relief valve body 111 to ensure sealing performance. The seal 112 is disposed at the end of the pressure relief valve body 111 and is used to cooperate with the housing 12 to achieve an effective seal between the pressure relief valve body 111 and the housing 12, so that the pressure relief valve body 111 can work effectively.

[0044] The seal 112 is constructed as an elastic element and is at least partially inclined relative to the end face of the pressure relief valve body 111 in a direction radially away from the pressure relief port. During the process of placing the pressure relief valve assembly 11 in the pressure relief valve mounting hole 121 of the housing 12, the seal 112 can deform under the pressure between the housing 12 and the end face of the pressure relief valve body 111. This not only ensures tight contact between the seal 112 and the housing 12 and the end face of the pressure relief valve body 111, but also allows the seal 112 to resist pressure by its elastic restoring force when subjected to high-pressure gas impact, preventing leakage and improving sealing performance.

[0045] When the temperature of compressor 1 rises, seal 112 absorbs the energy from the increased surface pressure of housing 12 due to thermal expansion, thus preventing further increase in surface pressure and avoiding yielding of the sealing material of seal 112. When compressor 1 cools down, seal 112 returns to its original shape, maintaining the initial surface pressure of housing 12. Furthermore, if the surface of housing 12 yields due to high temperature and pressure, seal 112 provides compensation, mitigating the yielding amount and preventing leakage caused by a sharp drop in surface pressure, thus ensuring the stability and sealing performance of pressure relief valve assembly 11 under high-temperature conditions.

[0046] Therefore, according to the present invention, the pressure relief valve assembly 11 achieves effective sealing between the pressure relief valve body and the housing 12 by setting an inclined and elastic sealing element 112, while maintaining stability under high temperature and high pressure environment, effectively preventing leakage, and realizing a safe and reliable pressure relief function.

[0047] It should be noted that the shape of the seal 112 is not limited in this invention. As long as the seal 112 can be inclined and has the ability to deform elastically to adapt to the compression between the housing 12 and the end face of the pressure relief valve body 111, and can maintain or restore its sealing performance during thermal expansion and contraction, it can be applied to the pressure relief valve assembly 11 of this invention. For example, the seal 112 can be designed as a cone, wedge, wave, or other irregular shape to better adapt to different installation conditions and working environments.

[0048] According to some embodiments of this utility model, the compressor 1 has a high-pressure chamber and a low-pressure chamber separated from each other. The high-pressure chamber is equipped with a pump body, while the low-pressure chamber is equipped with a motor. After the external refrigerant enters the low-pressure chamber, it undergoes heat exchange to cool the motor. At the same time, the liquid refrigerant absorbs heat and evaporates into a gaseous state. The gaseous refrigerant enters the cylinder of the compressor, where it is compressed into a high-temperature, high-pressure gas. Subsequently, the refrigerant is discharged into the high-pressure chamber, where oil-gas separation occurs. Finally, the gaseous refrigerant is discharged from the compressor 1.

[0049] According to some embodiments of the present invention, the sealing element 112 is at least partially inclined away from the end face of the pressure relief valve body 111 in a direction radially away from the pressure relief port. Inclination means that the outer edge of the sealing element 112 relative to its end face relative to the pressure relief valve body 111 forms a certain angle in the direction toward the housing 12. This allows the sealing element 112 to better adapt to and fit the surface of the housing 12 during installation, increases the contact area between the sealing element 112 and the housing 12, and enhances its sealing effect and elastic recovery ability under high pressure.

[0050] According to some embodiments of this utility model, such as Figure 3 As shown, the seal 112 is constructed as a conical ring and has a through-hole to avoid the pressure relief port. Therefore, the shape of the seal 112 resembles the annular portion left after a cone has been cut, which helps the seal 112 to deform between the end faces of the housing 12 and the pressure relief valve body 111, providing a better sealing effect because the conical ring can more effectively adapt to and fill the gap between the housing 12 and the pressure relief valve body 111. The through-hole avoids the pressure relief port on the pressure relief valve body 111, allowing the pressure relief port to connect with the pressure relief channel, so that high-pressure gas inside the housing 12 can flow out through the pressure relief port and the through-hole, thereby achieving the purpose of pressure relief.

[0051] According to some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, a protrusion 1111 is formed at one end of the pressure relief valve body 111. The protrusion 1111 is used to facilitate the setting of a pressure relief port and the installation of a sealing element 112. A pressure relief port is provided on the protrusion 1111, and the sealing element 112 is sleeved on the outer periphery of the protrusion 1111. The sealing element 112 is installed by sleeved on the outer periphery of the protrusion 1111, which is convenient and reliable, and ensures good contact and sealing effect between the sealing element 112 and the protrusion 1111, thereby preventing gas leakage from the gap between the pressure relief valve body 111 and the housing 12.

[0052] According to some embodiments of this utility model, the thickness of the seal 112 is h and satisfies: 0.2mm ≤ h ≤ 2mm. Therefore, in these embodiments of this utility model, the thickness h of the seal 112 must be greater than or equal to 0.2 mm and less than or equal to 2 mm. The thickness range of the seal 112 is determined based on the surface pressure required for sealing to ensure that the seal 112 can provide sufficient sealing effect under different operating conditions.

[0053] By controlling the thickness of the seal 112 between 0.2 mm and 2 mm, it can be ensured that the seal 112 provides sufficient sealing effect while also having good elasticity and durability. This helps to maintain the stability and reliability of the seal 112 under harsh working conditions such as high pressure and high temperature, thereby ensuring the overall performance of the pressure relief valve assembly 11.

[0054] According to some embodiments of this utility model, the sealing element 112 includes a base portion and an elastic element. The base portion is constructed as a conical ring to more effectively adapt to and fill the gap between the housing 12 and the pressure relief valve body 111. The flexible element is disposed on at least a portion of the outer surface of the base portion; wherein the base portion is constructed as a metal part. The base portion is made of a metal material with high yield strength, so that the base portion is not easily plastically deformed when subjected to large pressure, thereby ensuring the stability and durability of the sealing element 112. By providing a flexible element on at least a portion of the outer surface of the base portion, the sealing performance and adaptability of the sealing element 112 can be further enhanced. The flexible element is made of an elastic material, such as rubber, silicone, or soft metal. Elastic materials have good elasticity and resilience, can deform under pressure, and quickly return to their original shape after the pressure is released. When the sealing element 112 is installed between the housing 12 and the pressure relief valve body 111, it can fill small gaps, thereby effectively preventing gas leakage. In addition, since the flexible element has a certain degree of elasticity and buffering effect, it can also absorb and disperse pressure.

[0055] According to some embodiments of this utility model, the outer periphery of the pressure relief valve body 111 is formed with an external thread, which is a helical protrusion used for connection or fixation with other components having corresponding recesses (i.e., internal threads). An internal thread is formed within the pressure relief valve mounting hole 121 to mate with the external thread. The internal thread is a helical recess used to mate with the external thread to achieve connection, sealing, or fixation. Through the engagement of the external and internal threads, the pressure relief valve body 111 can be securely installed within the pressure relief valve mounting hole 121. Furthermore, during the process of screwing the pressure relief valve body 111 into the pressure relief valve mounting hole 121, the sealing element 112 is gradually compressed, resulting in elastic deformation and achieving a better sealing effect.

[0056] According to some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the pressure relief valve body 111 includes a mating section 1112, the outer periphery of which is formed with external threads, allowing the mating section 1112 to be connected or fixed to the pressure relief valve mounting hole 121. By rotating the mating section 1112, the pressure relief valve body 111 can be securely installed in the pressure relief valve mounting hole 121.

[0057] The pressure relief valve body 111 also includes a sealing section 1113, which is connected to one end of the mating section 1112 to achieve a sealing function. At least a portion of the sealing section 1113 is configured such that its diameter gradually decreases in the direction away from the mating section 1112. The gradually decreasing diameter of the sealing section 1113 provides a gradually compressible area for the seal 112. When the pressure relief valve body 111 is screwed into the pressure relief valve mounting hole 121, the seal 112 is subjected to pressure from the tapered surface formed by the gradually decreasing diameter of the sealing section 1113. The pressure gradually increases as the seal 112 moves towards the end of the sealing section 1113. This gradually increasing pressure helps ensure that the seal 112 is evenly stressed during installation, thereby forming a continuous and tight sealing surface and improving the sealing effect. The end of the sealing section 1113 is provided with a pressure relief port and abuts against the seal 112, thus the end of the sealing section is used to mate with the housing 12, and the seal 112 performs a sealing function between the end of the sealing section 1113 and the housing 12.

[0058] According to some embodiments of this utility model, such as Figure 3 and Figure 4As shown, the pressure relief valve body 111 also includes a mounting section 1114, which is located at the other end of the mating section 1112, facilitating the fixing of the pressure relief valve body 111 to the pressure relief valve mounting hole 121. The mounting section 1114 is constructed as a regular polygon and / or has polygonal mounting holes formed on its end face. The mounting section 1114 can be constructed as a regular polygon (such as a square, regular hexagon, etc.), allowing the pressure relief valve body 111 to be rotated through the outer edge of the mounting section 1114 using a wrench, pliers, or other tools. The regular polygonal shape provides a uniform force distribution point, making the rotation and fixing process more stable and reliable. Polygonal mounting holes (such as bolt holes, threaded holes, etc.) can also be formed on the end face of the mounting section 1114. The polygonal mounting holes allow the pressure relief valve body 111 to be fixed to the pressure relief valve mounting hole 121 using bolts, nuts, or other fasteners, making installation convenient.

[0059] According to some embodiments of this utility model, the sealing element 112 abuts against the bottom wall of the pressure relief valve mounting hole 121 and the end face of the pressure relief valve body 111 on both sides in the thickness direction, respectively. Therefore, when the pressure relief valve assembly 11 is installed into the pressure relief valve mounting hole 121, the sealing element 112 is sandwiched between the bottom wall of the pressure relief valve mounting hole 121 and the end face of the pressure relief valve body 111. In other words, the side of the sealing element 112 facing the bottom wall of the pressure relief valve mounting hole 121 is in close contact with the bottom wall of the pressure relief valve mounting hole 121, while the side of the sealing element 112 facing the pressure relief valve body 111 is in close contact with the end face of the pressure relief valve body 111. This allows the sealing element 112 to provide an effective seal between the housing 12 and the pressure relief valve body 111, preventing high-pressure gas from leaking out from the gap between the pressure relief valve assembly 11 and the housing 12.

[0060] According to some embodiments of this utility model, the compressor 1 uses CO2 refrigerant. CO2 refrigerant has high heat transfer performance and thermal efficiency, enabling a high energy efficiency ratio. Compressors using CO2 refrigerant have higher energy efficiency, thereby reducing energy consumption and operating costs. The physical properties of CO2 refrigerant allow it to operate over a wide temperature range, making it suitable for various refrigeration and heat pump applications, thus giving the compressor wider applicability.

[0061] According to some embodiments of this utility model, compressor 1 is constructed as a rotary compressor. A rotary compressor compresses gas through the rotation of one or more rotating components, offering advantages such as small size, light weight, and low noise, thus contributing to improved space utilization efficiency and weight reduction in vehicles.
