[0006] Further, in two adjacent material passing ports, one material passing port is located at the top of the foaming cavity, and the other material passing port is located at the bottom of the foaming cavity.

[0007] Further, the cover body includes a first split body and a second split body, and the first split body and the second split body are oppositely connected to form an installation cavity for wrapping the compressor.

[0008] Further, a clamping structure is provided at the connection between the first split body and the second split body.

[0009] Further, the clamping structure includes a clamping groove and a clamping buckle that cooperates with the clamping groove for clamping. The clamping groove is provided at both ends of the first split body, and the clamping buckle is correspondingly provided at both ends of the second split body; or the clamping groove and the clamping buckle are respectively provided at both ends of the first split body, and the second split body is correspondingly provided with the clamping buckle and the clamping groove.

[0010] Further, the cover body further includes a third split body, which is disposed on the tops of the first split body and the second split body, and a pipe hole is formed in the third split body.

[0011] Further, the cover body includes an inner plate, an outer plate and two lining plates. The inner plate is attached to the outer wall of the compressor. The outer plate surrounds the outside of the inner plate and there is a gap between the outer plate and the inner plate. One of the lining plates connects the inner plate and the outer plate at the top, and the other lining plate connects the inner plate and the outer plate at the bottom. A foaming cavity is formed among the inner plate, the outer plate and the lining plates. The flow guide plate is arranged perpendicular to the lining plate and a material passing port is formed between the flow guide plate and one of the lining plates.

[0012] Further, the inner plate includes a plurality of inner folded edges, and the outer plate includes a plurality of outer folded edges. The plurality of outer folded edges correspond to the plurality of inner folded edges one by one.

[0028] To make the technical problems solved by this application, the technical solutions adopted, and the achieved technical effects clearer, the technical solutions of the embodiments of this application will be further described in detail below. Obviously, the described embodiments are only part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of this application.

[0029] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific situations.

[0030] In this application, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above", and "on the top" of the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the first feature is at a higher horizontal height than the second feature. The first feature being "below", "below", and "under the bottom" of the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the first feature is at a lower horizontal height than the second feature.

[0031] Such as Figures 1 - 10As shown in the figure, this embodiment provides a press cover, including: a cover body 1, a plurality of flow guiding plates 2, and polyurethane foam material; the cover body 1 covers the outer wall of the compressor, a foaming cavity 101 is formed inside the cover body 1, the plurality of flow guiding plates 2 are arranged at intervals in the circumferential direction in the foaming cavity 101, and the foaming cavity 101 is divided into a plurality of cavities 1011, a material passing port 104 is left between the flow guiding plate 2 and the top surface of the foaming cavity 101, and / or a material passing port 104 is left between the flow guiding plate 2 and the bottom surface of the foaming cavity 101, the material passing port 104 communicates with two adjacent cavities 1011, a feed port 102 and an air outlet 103 are formed on the cover body 1, the polyurethane foam material is introduced into the foaming cavity 101 through the feed port 102, and then the air in the foaming cavity 101 is extruded and discharged from the air outlet 103.

[0032] Based on the above solution, first, the cover body 1 is accurately covered on the outer wall of the compressor, and a closed or semi-closed space, that is, the foaming cavity 101, is formed inside. This cover body 1 serves as the basis of the noise reduction structure and can effectively isolate part of the noise generated by the compressor. Inside the foaming cavity 101 in the cover body 1, a plurality of flow guiding plates 2 are arranged at intervals in the circumferential direction. The function of these flow guiding plates 2 is to divide the foaming cavity 101 into a plurality of relatively independent cavities 1011. At the same time, a material passing port 104 is left between them and the top surface or the bottom surface of the foaming cavity 101. These material passing ports 104 allow the polyurethane foam material to flow freely during the injection process and extrude the air in the adjacent cavities 1011. Through the feed port 102 formed on the cover body 1, the polyurethane foam material is injected into the foaming cavity 101. As the foaming material is continuously injected, it will quickly expand and fill the entire foaming cavity 101, and at the same time, it will extrude and push the air in the cavity 1011 to be discharged through the material passing ports 104 between the flow guiding plates 2 and the air outlet 103 on the cover body 1. During this process, the polyurethane foam material not only fills the space around the compressor but also forms a dense and sound-insulating foam layer. After the polyurethane foam material is expanded in the foaming cavity 101, it will gradually solidify and form a firm and significantly sound-insulating foam structure. This structure tightly wraps around the compressor and effectively blocks the noise propagation path.

[0033] In summary, due to the presence of foaming pores in the polyurethane foam material, when the polyurethane foam material is filled in the foaming cavity 101, noise penetrates the surface of the housing 1 and enters the foaming cavity 101. The numerous and dense foaming pores will conduct frictional movement on medium and high-frequency sounds, and the generated heat will consume the noise. The noise sources around the compressor are effectively isolated, reducing the propagation and reflection of noise, thus significantly improving the noise reduction effect. Compared with traditional sheet metal sound insulation covers or sponge combinations, this foaming structure has more advantages in sound insulation performance; moreover, the production cost of the polyurethane foam material is relatively low, and its filling process is simple and fast, without complex processing and assembly procedures. In addition, by adjusting the number and position of the flow guiding plates 2, the shape and size of the foaming cavity 101 can be flexibly controlled to adapt to compressors of different models and specifications. This design flexibility enables the compressor housing to be widely applied to various heat pump products. At the same time, the polyurethane foam material has good weather resistance and corrosion resistance, can maintain a stable sound insulation effect in various harsh environments, and its tightly wrapped structure also helps to protect the compressor from external impacts and damage, improving the overall reliability of the product.

[0034] It should be noted that multiple flow guiding plates 2 are provided in the foaming cavity 101 and the foaming cavity 101 is divided into multiple cavities 1011 mainly to guide the heated polyurethane foam material, ensuring that the polyurethane foam material first fills one cavity 1011 and then enters another cavity 1011, thereby ensuring that the polyurethane foam material can fill the entire foaming cavity 101.

[0035] Furthermore, among two adjacent material passing ports 104, one material passing port 104 is located at the top of the foaming cavity 101, and the other material passing port 104 is located at the bottom of the foaming cavity 101. The vertical arrangement of the material passing ports 104 makes the overall flow direction of the polyurethane foam material wavy. The staggered vertical arrangement of the material passing ports 104 not only promotes the uniform distribution of the polyurethane foam material but also makes the overall flow direction of the polyurethane foam material present a wavy form during the filling process. The wavy flow pattern has significant advantages. First, it ensures that the polyurethane foam material can penetrate into every corner of the foaming cavity 101 more fully, reducing voids or bubbles caused by poor flow, thereby improving the density and sound insulation effect of the foaming layer; second, the wavy flow also promotes the close contact between the polyurethane foam material and the flow guiding plates 2 and the inner wall of the housing 1, enhancing the bonding force between the foaming layer and the surrounding structure and further improving the overall strength and durability of the compressor housing. In addition, the wavy flow pattern also helps to more effectively discharge the air in the cavity 1011 during the foaming process. As the polyurethane foam material is continuously injected, the air is gradually squeezed and moves upward or downward along the wavy flow path and finally is discharged through the air outlet 103. This orderly exhaust process reduces the possibility of air retention, improves the foaming efficiency, and ensures the quality of the foaming layer.

[0036] In some embodiments, the housing 1 includes a first split body 105 and a second split body 106. The first split body 105 and the second split body 106 are oppositely connected to form an installation cavity 113 for wrapping the compressor. Since the shape of the compressor may be irregular or there may be protruding parts, it may be difficult for the traditional integral housing 1 to fit perfectly. The split design allows the first split body 105 to wrap a part of the compressor first, and then, after adjusting the position according to actual needs, the second split body 106 can be spliced on, so as to achieve a more complete and tighter wrapping of the compressor. This not only improves the sound insulation effect but also helps to reduce the transmission of vibration and noise. The split design makes the installation process of the housing 1 more simple and fast. The operator can more easily wrap larger components or inaccessible areas without worrying about the entire housing 1 being difficult to operate due to its large size or complex shape. Moreover, the split design also facilitates the quick disassembly of the housing 1 when maintaining and replacing the compressor. In addition, different compressor models and specifications may vary, and the split design enables the compressor housing to adapt to these changes more flexibly. By adjusting the size, shape or connection method of the first split body 105 and the second split body 106, different models of compressors can be easily adapted, thus reducing production costs and inventory pressure. On the production line, the split design allows parallel operation, that is, the first split body 105 and the second split body 106 can be produced or prepared simultaneously, and then spliced together in the final assembly stage. This production method helps to improve production efficiency, shorten the production cycle and reduce production costs.

[0037] Furthermore, a clamping structure 108 is provided at the connection between the first split body 105 and the second split body 106. During the installation process, the first split body 105 can be first tightly wrapped around a part of the compressor, and then the second split body 106 can be accurately spliced on through the clamping structure 108 to achieve seamless docking.

[0038] Still further, the clamping structure 108 includes a clamping groove 1081 and a clamping buckle 1082 that cooperates with the clamping groove 1081. The clamping groove 1081 is fixed at both ends of the first split body 105, and the corresponding clamping buckle 1082 is accurately provided at both ends of the second split body 106. When the first split body 105 and the second split body 106 need to be combined, simply align the clamping buckle 1082 on the second split body 106 with the clamping groove 1081 on the first split body 105 and apply appropriate pressure, and the clamping buckle 1082 will smoothly snap into the clamping groove 1081 to form a stable connection.

[0039] To enhance the flexibility and adaptability of the design, another configuration scheme is provided: the card slots 1081 and the buckles 1082 can be respectively arranged at both ends of the first split body 105, and the corresponding buckles 1082 and card slots 1081 that match these card slots 1081 and buckles 1082 are arranged on the second split body 106. This interchangeable snap connection design allows the positions of the card slots 1081 and the buckles 1082 to be adjusted according to actual needs in specific situations, so as to easily cope with compressors of different shapes or sizes.

[0040] Meanwhile, the cover body 1 further includes a third split body 107. The third split body 107 is arranged on the top of the first split body 105 and the split body, and a pipe hole 109 is opened on the third split body 107. The third split body 107 is placed on the top of the first split body 105 and the second split body 106, forming a complete cover body 1 structure that wraps the compressor all around. The design of the third split body 107 not only enhances the overall stability of the cover body 1, but also fully considers the pipeline connection requirements that may be involved during the operation of the compressor. Therefore, on the third split body 107, the pipe holes 109 are skillfully opened. The positions and sizes of these pipe holes 109 are accurately calculated to ensure that they can perfectly adapt to various pipelines on the compressor, such as cooling water pipes, exhaust pipes, etc., so as to achieve the orderly arrangement and smooth connection of the pipelines. By opening the pipe holes 109, the third split body 107 not only avoids the cumbersome process of drilling or cutting on the cover body 1, reduces the installation difficulty and cost, but also ensures the integrity and aesthetics of the cover body 1. At the same time, the design of the pipe holes 109 also takes into account the sealing requirements, and appropriate sealing materials or sealing structures are used to prevent the leakage of noise and air, further improving the noise reduction effect.

[0041] Furthermore, the housing 1 includes an inner plate 110, an outer plate 111 and two lining plates 112. The inner plate 110 is attached to the outer wall of the compressor. The outer plate 111 surrounds the outside of the inner plate 110 with a gap left between them. One of the lining plates 112 connects the inner plate 110 and the outer plate 111 at the top, and the other lining plate 112 connects the inner plate 110 and the outer plate 111 at the bottom. A foaming cavity 101 is formed among the inner plate 110, the outer plate 111 and the lining plates 112. The deflector plate 2 is arranged perpendicular to the lining plate 112 and a material passing port 104 is formed between the deflector plate 2 and one of the lining plates 112. The inner plate 110, as the part directly contacting the compressor, is designed to be able to closely attach to the outer wall of the compressor. This attachment design not only enhances the fixing effect of the housing 1 on the compressor, but also helps to reduce the noise transmission caused by vibration. The outer plate 111 surrounds the outside of the inner plate 110, and a gap is deliberately left between them. This design not only reserves space for subsequent sound insulation treatment, but also enhances the heat insulation performance of the housing 1. To stabilize the structure of the entire housing 1, we have provided a lining plate 112 at the top and bottom of the housing 1 respectively. These two lining plates 112 connect the inner plate 110 and the outer plate 111 respectively, forming a solid framework. Inside this framework, the inner plate 110, the outer plate 111 and the lining plates 112 together constitute a foaming cavity 101. This foaming cavity 101 is the key area where the polyurethane foaming material is injected and expanded. Through the filling of the foaming material, a dense sound insulation foam layer can be formed, effectively isolating the noise and vibration generated during the operation of the compressor.

[0042] To optimize the flow and distribution of the foaming material, deflector plates 2 are arranged in the foaming cavity 101. These deflector plates 2 are arranged perpendicular to the lining plates 112 and a material passing port 104 is formed between the deflector plates 2 and one of the lining plates 112. The design of the material passing port 104 enables the foaming material to smoothly flow into each corner of the foaming cavity 101 along the guidance of the deflector plates 2, ensuring the uniformity and consistency of the foaming layer. This design not only improves the foaming efficiency, but also guarantees the quality of the foaming layer, thereby further enhancing the sound insulation effect of the housing 1.

[0043] Among them, the inner plate 110 includes a plurality of inner folding edges 1101, and the outer plate 111 includes a plurality of outer folding edges 1111. The plurality of outer folding edges 1111 correspond to the plurality of inner folding edges 1101 one by one. A sub-chamber is formed between the inner folding edge 1101, the outer folding edge 1111, and the lining plate 112 at the corresponding position. The sub-chamber is a part of the foaming chamber 101. The flow guide plate 2 is disposed in the sub-chamber and divides the sub-chamber into two symmetrical parts. The inner plate 110 includes a plurality of inner folding edges 1101, and these inner folding edges 1101 extend along the outer wall edge of the compressor to ensure that the inner plate 110 can closely fit the surface of the compressor. Correspondingly, the outer plate 111 also includes a plurality of outer folding edges 1111, and these outer folding edges 1111 correspond to the inner folding edges 1101 one by one. The distance between them forms a specific gap. This design not only enables the inner plate 110 and the outer plate 111 to maintain a stable connection but also reserves space for subsequent filling of sound insulation materials. More importantly, a plurality of sub-chambers are jointly formed between these inner folding edges 1101, outer folding edges 1111, and the lining plate 112 at their corresponding positions. These sub-chambers are refined parts of the foaming chamber 101 and are cleverly designed at key positions of the housing 1 to more effectively isolate noise and vibration. In each sub-chamber, a flow guide plate 2 is provided. These flow guide plates 2 are arranged perpendicular to the lining plate 112 and cleverly divide the sub-chamber into two symmetrical parts. This design not only optimizes the flow path of the foaming material to ensure that the foaming material can be evenly filled into every corner of the sub-chamber but also enhances the structural strength of the foaming layer, enabling it to better withstand the vibration and impact during the operation of the compressor.

[0044] As an optional specific implementation, the flow guide plate 2 divides the sub-chamber into two asymmetrical parts. This design is based on in-depth research on the flow characteristics of polyurethane foaming material and sound insulation effect. In some cases, in order to more precisely control the filling shape and density of the polyurethane foaming material, or to optimize the sound insulation effect in a specific area, the flow guide plate 2 can be designed into an asymmetrical shape to form two asymmetrical parts in the sub-chamber. By adjusting the shape and position of the flow guide plate 2, the flow rate and filling amount of the polyurethane foaming material in different areas can be controlled, so as to form a sound insulation foam layer with different characteristics in the sub-chamber. This asymmetrical design may be more suitable for certain specific compressor models or operating conditions because it can more precisely meet specific sound insulation and vibration reduction requirements.

[0045] At the same time, this asymmetrical design requires precise calculation and simulation in the design stage to ensure that the polyurethane foaming material can flow and fill as expected. In addition, strict control of process parameters is also required during the installation process to ensure that the flow guide plate 2 can be accurately installed in the predetermined position and achieve the expected sound insulation effect.

[0046] It should be noted that when the cover body 1 is assembled, pressure needs to be applied to the two lining plates 112, the inner plate 110 and the outer plate 111 for pressure holding to ensure that the inner plate 110 and the outer plate 111 are both in contact with the lining plate 112, and then pouring is carried out. Since the polyurethane foaming material has strong viscosity, there is no need to fix the plates with screws.

[0047] On the other hand, a heat pump is also provided, including the press cover as described above and a floating chassis 4. Positioning grooves 401 and limiting grooves 402 are formed on the floating chassis 4. A positioning portion 114 that cooperates with the positioning groove 401 for positioning and a limiting portion 115 that cooperates with the limiting groove 402 for limiting are convexly provided at the bottom of the cover body 1. The floating chassis 4 serves as a support structure for the compressor. It not only has the characteristics of high strength and corrosion resistance, but also has the positioning groove 401 and the limiting groove 402 formed on its surface. The design of these two grooves is extremely ingenious. They are respectively used to cooperate with specific structures at the bottom of the press cover to achieve accurate positioning and stable limiting. At the bottom of the press cover, we have specially designed a positioning portion 114 that matches the positioning groove 401 and a limiting portion 115 that cooperates with the limiting groove 402. During the installation process, just gently place the press cover on the floating chassis 4, and the positioning portion 114 will automatically slide into the positioning groove 401 to achieve preliminary positioning. Subsequently, the limiting portion 115 will be in close contact with the limiting groove 402 to ensure that the press cover is firmly fixed in both the horizontal and vertical directions. This design not only simplifies the installation process of the heat pump, reduces the installation difficulty, but also greatly improves the installation accuracy and stability. At the same time, due to the adoption of the floating chassis 4, the compressor can better isolate the vibration transmission with the heat pump body during operation, reduce the noise transmission, and further improve the user experience. Among them, the limiting portion 115 and the limiting groove 402 are specifically of a snap 1082 type structure.

[0048] Meanwhile, the heat pump further includes a compressor, a connecting pipe group 5, and a fastener. The compressor is installed in the installation cavity 113, the connecting pipe group 5 is connected to the compressor and passes through the top of the housing 1. A seal 3 is provided between the connecting pipe group 5 and the housing 1. An outwardly extending locking flange 116 is formed on the outer wall of the housing 1, and a locking hole 117 is formed in the locking flange 116. The fastener passes through the locking hole 117 and locks to the floating chassis 4. As the core component of the heat pump system, the compressor is installed in the installation cavity 113 of the compressor housing. This design not only protects the compressor from the external environment but also effectively reduces the noise generated during the operation of the compressor through the sound insulation structure of the compressor housing. The connecting pipe group 5 is responsible for connecting the compressor to other system components (such as evaporators, condensers, etc.) to achieve the transfer and conversion of thermal energy. These connecting pipe groups 5 cleverly pass through the top of the housing 1 and are equipped with seals 3 to ensure the sealing between them and the housing 1. In this way, even in a high-pressure or high-temperature working environment, the leakage of refrigerants or other working media can be effectively prevented.

[0049] To further enhance the stability of the heat pump system, we designed an outwardly extending locking flange 116 on the outer wall of the housing 1. The locking flange 116 not only increases the structural strength of the housing 1 but also provides a reliable support point for its connection with the floating chassis 4. A locking hole 117 is formed in the locking flange 116 so that the housing 1 can be firmly locked to the floating chassis 4 through a fastener. This design not only simplifies the installation process but also ensures the stability and safety of the heat pump system during operation. Simply put, the compressor housing can be stably locked to the floating chassis 4 through a fastener, and the fastener is specifically a screw.
