Description

Technical Field

[0001] This application relates to the field of refrigeration technology, and in particular to a shell-and-tube condenser and refrigeration unit. Background Technology

[0002] Shell-and-tube heat exchangers are a crucial component of air conditioning refrigeration systems, playing a vital role in the system's heat exchange efficiency. In related technologies, the compressor discharges high-temperature, high-pressure gaseous refrigerant through the inlet into the condenser, where it exchanges heat with the heat exchange tubes. However, the gaseous refrigerant has a certain velocity, and when it enters the condenser, it causes significant impact on the heat exchange tubes at the inlet, reducing their lifespan. Furthermore, due to the limited size of the inlet, the gaseous refrigerant can only make partial contact with the heat exchange tubes, resulting in insufficient contact and low heat exchange efficiency. Summary of the Invention

[0003] This application provides a shell-and-tube condenser and a refrigeration unit to solve the technical problems of gaseous refrigerant discharged from the compressor causing significant impact on the heat exchange tubes in the condenser when it enters the condenser, thus affecting the service life of the condenser; and the insufficient contact between the gaseous refrigerant and the heat exchange tubes, resulting in low heat exchange efficiency.

[0004] Therefore, in a first aspect, embodiments of this application provide a shell-and-tube condenser, comprising:

[0005] The condenser body has a heat exchange chamber, an air inlet, and a liquid outlet;

[0006] A first anti-impact component is disposed within the heat exchange chamber, dividing the heat exchange chamber into a buffer chamber and a heat exchange chamber. An air inlet connects to the buffer chamber, and a liquid outlet connects to the heat exchange chamber. Multiple uniformly distributed air distribution holes are present on the first anti-impact component, connecting the buffer chamber and the heat exchange chamber.

[0007] The intake pipe assembly includes a pipe body inserted into the intake port and a second anti-impact member located in the buffer chamber. The second anti-impact member is spaced apart at the outlet end of the pipe body and forms an outlet notch with the outlet end of the pipe body. The outlet notch extends radially along the pipe body.

[0008] In one possible implementation, the size of the vent notch is greater than or equal to the radial dimension of the pipe body; and / or,

[0009] The pipe body is provided with a first arc-shaped curved surface, which is positioned facing the second anti-impact component.

[0010] In one possible implementation, the intake manifold assembly further includes a connector, through which the second anti-impact member is connected to the manifold body.

[0011] In one possible implementation, the second anti-impact member is inclined, with its free end facing the first anti-impact member and its connecting end facing the pipe body; and / or,

[0012] The second anti-impact component has a second arc-shaped curved surface, which faces the tube body.

[0013] In one possible implementation, the intake pipe assembly further includes a connecting flange and a seal. The connecting flange is located at the end of the pipe body away from the second anti-impact element, and the seal is located on the side of the connecting flange away from the pipe body. The pipe connecting the compressor is connected to the condenser body through the connecting flange.

[0014] In one possible implementation, the first anti-impact component includes an anti-impact base plate and at least two anti-impact side plates. The two anti-impact side plates are respectively disposed on the two long sides of the anti-impact base plate, and the two anti-impact side plates are set at an angle to the anti-impact base plate. The anti-impact base plate is connected to the inner wall of the condenser body through the two anti-impact side plates.

[0015] In one possible implementation, the anti-impact base plate includes a clearance area and an air vent area. The clearance area is provided corresponding to the air intake pipe assembly, and multiple air vents are distributed in the air vent area. The size of the air vents is smaller the closer they are to the clearance area.

[0016] In one possible implementation, the condenser body includes a shell and a heat exchange tube assembly, a first anti-impact member is disposed inside the shell and divides the shell to form a buffer chamber and a heat exchange chamber, an air inlet pipe assembly is inserted into the shell through an air inlet, and the heat exchange tube assembly is disposed in the heat exchange chamber.

[0017] In one possible implementation, the heat exchange tube assembly includes multiple heat exchange tube bodies and multiple support members. The multiple heat exchange tube bodies are stacked in a heat exchange chamber, and the heat exchange tube bodies extend axially along the shell. The multiple support members are spaced apart axially along the shell in the heat exchange chamber to provide support for the multiple heat exchange tube bodies.

[0018] Secondly, this application also provides a refrigeration unit, including a throttling unit, an evaporator and a compressor connected in sequence. The refrigeration unit also includes a shell-and-tube condenser as described above. The shell-and-tube condenser is located between the compressor and the throttling unit. The compressor is connected to the inlet pipe assembly of the shell-and-tube condenser. The throttling unit is connected to the liquid outlet of the shell-and-tube condenser to form a refrigerant circulation loop.

[0019] According to the shell-and-tube condenser and refrigeration unit provided in the embodiments of this application, the shell-and-tube condenser includes: a condenser body having a heat exchange chamber, an air inlet, and a liquid outlet; a first anti-impact member disposed within the heat exchange chamber, the first anti-impact member dividing the heat exchange chamber into a buffer chamber and a heat exchange chamber, the air inlet communicating with the buffer chamber, and the liquid outlet communicating with the heat exchange chamber, the first anti-impact member having a plurality of uniformly distributed gas equalization holes communicating with the buffer chamber and the heat exchange chamber; and an air inlet pipe assembly including a pipe body inserted into the air inlet and a second anti-impact member located within the buffer chamber, the second anti-impact member being spaced apart at the air outlet end of the pipe body and forming an air outlet notch with the air outlet end of the pipe body, the air outlet notch extending radially along the pipe body. The technical solution of this application, by optimizing the specific configuration of the shell-and-tube condenser, reduces the impact force of gaseous refrigerant on the heat exchange tubes, extending the service life of the condenser; simultaneously, it increases the contact area between the gaseous refrigerant and the heat exchange tubes, improving heat exchange efficiency. Specifically, the shell-and-tube condenser is configured as a combination of at least a condenser body, a first anti-impact component, and an inlet pipe assembly. The condenser body has an inlet and an outlet. High-temperature, high-pressure gaseous refrigerant discharged from the compressor enters the heat exchange chamber of the condenser body through the inlet, exchanges heat to form liquid refrigerant, and exits the shell-and-tube condenser through the outlet. The first anti-impact component is disposed in the heat exchange chamber of the condenser body and divides the heat exchange chamber into a buffer chamber and a heat exchange chamber with relatively independent functions. The inlet pipe assembly is inserted into the inlet. Thus, the first anti-impact component can prevent the refrigerant from being discharged. The gas entering the buffer chamber from the inlet pipe assembly forms a buffer, reducing the flow velocity of the gas entering the condenser body, minimizing the impact of the gas on the condenser body, and extending the service life of the shell-and-tube condenser. Simultaneously, the reduced-velocity gas fills the entire buffer chamber and is evenly distributed above the heat exchange chamber. When it enters the heat exchange chamber through the multiple gas equalization holes arranged on the first anti-impact component, it can simultaneously contact the heat exchange chamber at least axially along the condenser body, increasing the heat exchange contact area between the gas and the heat exchange chamber, improving heat exchange efficiency, and preventing the gas from only contacting the heat exchange chamber at the inlet. Furthermore, the inlet pipe assembly is configured as a combination of at least a pipe body and a second anti-impact component. The pipe body provides the condenser body with gas flowing axially, and the second anti-impact component changes the gas flow direction, allowing the axially flowing gas to enter the buffer chamber from the radially arranged outlet notch. This prevents the axially flowing gas from directly impacting the first anti-impact component and causing it to loosen, further enhancing the impact resistance of the shell-and-tube condenser.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] See Figures 1 to 3 This application provides a shell-and-tube condenser, which includes: a condenser body 100, a first anti-impact component 200, and an intake pipe assembly 300.

[0032] The condenser body 100 has a heat exchange chamber, an air inlet and a liquid outlet;

[0033] A first anti-impact component 200 is disposed within the heat exchange chamber, dividing the heat exchange chamber into a buffer chamber and a heat exchange chamber. An air inlet connects to the buffer chamber, and a liquid outlet connects to the heat exchange chamber. Multiple uniformly distributed air distribution holes 201 are present on the first anti-impact component 200, connecting the buffer chamber and the heat exchange chamber.

[0034] The intake pipe assembly 300 includes a pipe body 310 inserted into the intake port and a second anti-impact member 320 located in the buffer chamber. The second anti-impact member 320 is spaced apart at the outlet end of the pipe body 310 and forms an outlet notch 301 with the outlet end of the pipe body 310. The outlet notch 301 extends radially along the pipe body 310.

[0035] In this embodiment, by optimizing the specific configuration of the shell-and-tube condenser, the impact force of the gaseous refrigerant on the heat exchange tubes is reduced, thereby extending the service life of the condenser; at the same time, the contact area between the gaseous refrigerant and the heat exchange tubes is increased, thereby improving the heat exchange efficiency.

[0036] Specifically, the shell-and-tube condenser is configured as a combination of at least a condenser body 100, a first anti-impact component 200, and an inlet pipe assembly 300. The condenser body 100 has an inlet and an outlet. High-temperature, high-pressure gaseous refrigerant discharged from the compressor enters the heat exchange chamber of the condenser body 100 through the inlet, exchanges heat to form liquid refrigerant, and exits the shell-and-tube condenser through the outlet. The first anti-impact component 200 is disposed in the heat exchange chamber of the condenser body 100 and divides the heat exchange chamber into a buffer chamber and a heat exchange chamber with relatively independent functions. The inlet pipe assembly 300 is inserted into the inlet. Thus, the refrigerant can pass through the first anti-impact component... The 200-pair buffer system buffers the gas entering the buffer chamber from the inlet pipe assembly 300, reducing the flow rate of the gas entering the condenser body 100, decreasing the impact of the gas on the condenser body 100, and extending the service life of the shell-and-tube condenser. At the same time, the reduced gas velocity fills the entire buffer chamber and is evenly distributed above the heat exchange chamber. When the gas enters the heat exchange chamber through the multiple gas equalization holes 201 arranged on the first anti-impact component 200 for heat exchange, it can simultaneously contact the heat exchange chamber at least axially in the condenser body 100, increasing the heat exchange contact area between the gas and the heat exchange chamber, improving heat exchange efficiency, and preventing the gas from only contacting the heat exchange chamber at the corresponding part of the inlet for heat exchange.

[0037] Furthermore, the intake pipe assembly 300 is configured as a combined component including at least a pipe body 310 and a second anti-impact member 320. The pipe body 310 is used to provide gas flowing axially to the condenser body 100. The second anti-impact member 320 is used to change the gas flow direction, so that the axially flowing gas enters the buffer chamber from the radially arranged outlet notch 301, thereby reducing the flow velocity of the gas entering the buffer chamber. In this way, the axially flowing gas is prevented from directly impacting the first anti-impact member 200 and causing the first anti-impact member 200 to loosen, further enhancing the impact resistance of the shell-and-tube condenser.

[0038] As shown above, the gas with a relatively high velocity enters the condenser body 100 along the axial direction of the tube 310, and under the anti-impact barrier of the second anti-impact member 320, it enters the buffer chamber radially from the tube 310 and fills the entire buffer chamber. At this time, the gas velocity is reduced by the obstruction of the second anti-impact member 320. Then, it enters the heat exchange chamber through multiple gas equalization holes 201 arranged on the first anti-impact member 200 for heat exchange. At this time, the gas velocity is further reduced by the obstruction of the first anti-impact member 200, the overall gas flow rate is stable, and the impact force on the heat exchange chamber is almost negligible.

[0039] In one example, the air inlet is located at the middle position along the axial direction of the condenser body 100. Two air outlets 301 are provided, positioned opposite each other along the axial direction of the condenser body 100. This allows the gas entering from the inlet of the tube 310 to be diverted by the two outlets 301 and, guided by the second anti-impact member 320, flow to opposite ends of the buffer chamber along the axial direction, improving the uniformity of gas distribution along the axial direction of the condenser body 100 and enhancing the heat exchange efficiency and effect. Alternatively, when the air inlet is located at one end of the condenser body 100, only one outlet 301 can be provided, in which case the outlet 301 faces the other end of the condenser body 100.

[0040] In one possible implementation, the size of the venting notch 301 is greater than or equal to the radial dimension of the tube body 310.

[0041] In this embodiment, the dimensions of the venting notch 301 are optimized. Specifically, the dimensions of the venting notch 301 are set to be greater than or equal to the radial dimension of the pipe body 310. This ensures that gas does not accumulate inside the pipe body 310, improving gas flow. Since the venting notch 301 is a lateral opening rather than an axial opening, the axial distance between the venting end of the pipe body 310 and the second anti-impact member 320 must also be ensured to guarantee the venting space at the venting notch 301.

[0042] See Figure 1 and Figure 2 In one possible implementation, the pipe body 310 is provided with a first arc-shaped curved surface 311, which is positioned toward the second anti-impact member 320.

[0043] In this embodiment, the specific configuration of the pipe body 310 is optimized. Specifically, to increase the outlet space of the outlet notch 301, the outlet end face of the pipe body 310 is set as a first arc-shaped curved surface 311. In this way, by setting a portion of the outlet notch 301 as a curved surface, the gas flow rate at the outlet end of the pipe body 310 is increased through the curved outlet end face, thereby improving the smoothness of gas flow.

[0044] See Figure 1 and Figure 2 In one possible implementation, the intake pipe assembly 300 further includes a connector 330, through which the second anti-impact member 320 is connected to the pipe body 310.

[0045] In this embodiment, the specific configuration of the intake pipe assembly 300 is further optimized. Specifically, the intake pipe assembly 300 is configured as a combined component including at least a pipe body 310, a second anti-impact member 320, and a connector 330. The connector 330 extends along the wall of the pipe body 310, and there can be two connectors 330, which are positioned opposite each other on the diameter of the air outlet end of the pipe body 310. The second anti-impact member 320 has a plate-like structure, and its size is adapted to the size of the pipe body 310. The second anti-impact member 320 is connected to the pipe body 310 at intervals by the two connectors 330, thereby forming two air outlet notches 301 between the second anti-impact member 320, the connectors 330, and the pipe body 310. The addition of the connectors 330 further enhances the anti-impact performance of the second anti-impact member 320.

[0046] In one example, to improve assembly efficiency, the connector 330 is integrally formed with the tube body 310.

[0047] See Figure 1 and Figure 2 In one possible implementation, the second anti-impact member 320 is inclined, with its free end facing the first anti-impact member 200 and its connecting end facing the pipe body 310.

[0048] In this embodiment, the specific configuration of the second anti-impact member 320 is optimized. Specifically, the second anti-impact member 320 is inclined to guide the gas into the buffer chamber. In addition, since the second anti-impact member 320 constitutes a part of the gas outlet 301, its inclined configuration helps to increase the gas outlet space of the gas outlet 301.

[0049] When there are two air outlets 301, the second anti-impact member 320 is configured as a bent plate with a certain angle. The second anti-impact member 320 is higher in the middle and lower at both ends, with the two ends closer to the first anti-impact member 200. That is to say, the connection between the second anti-impact member 320 and the connector 330 is closer to the pipe body 310, while the two free ends of the second anti-impact member 320 are closer to the first anti-impact member 200. In this way, on the one hand, designing the air outlet 301 as a flared structure increases the amount of air discharged; on the other hand, the flared layout of the air outlet 301 facilitates the drainage of gas into the buffer chamber.

[0050] See Figure 1 and Figure 2 In one possible implementation, the second anti-impact member 320 is provided with a second arc-shaped curved surface 321, which is disposed toward the tube body 310.

[0051] In this embodiment, the specific configuration of the second anti-impact component 320 is optimized. Specifically, to improve the smoothness and fluidity of the second anti-impact component 320 in guiding gas flow, the side of the second anti-impact component 320 facing the pipe body 310 is set as a second arc-shaped curved surface 321.

[0052] See Figure 1 and Figure 2 In one possible implementation, the intake pipe assembly 300 further includes a connecting flange 340 and a seal 350. The connecting flange 340 is located at one end of the pipe body 310 away from the second anti-impact member 320, and the seal 350 is located on the side of the connecting flange 340 away from the pipe body 310. The pipe connecting the compressor is connected to the condenser body 100 through the connecting flange 340.

[0053] In this embodiment, the specific configuration of the intake pipe assembly 300 is further optimized. Specifically, the intake pipe assembly 300 is configured as a combination component including at least a pipe body 310, a second anti-impact member 320, a connecting flange 340, and a sealing member 350. The connecting flange 340 and the sealing member 350 are both located on the outside of the condenser body 100. The connecting flange 340 is used to connect with the pipe that connects to the compressor outlet, and the sealing member 350 is located between the pipe and the connecting flange 340. This improves the airtightness between the intake pipe assembly 300 and the compressor, preventing refrigerant leakage.

[0054] See Figure 1 and Figure 3 In one possible implementation, the first anti-impact member 200 includes an anti-impact base plate 210 and at least two anti-impact side plates 220. The two anti-impact side plates 220 are respectively disposed on the two long sides of the anti-impact base plate 210, and the two anti-impact side plates 220 are arranged at an angle to the anti-impact base plate 210. The anti-impact base plate 210 is connected to the inner wall of the condenser body 100 through the two anti-impact side plates 220.

[0055] In this embodiment, the specific configuration of the first anti-impact member 200 is optimized. Specifically, the first anti-impact member 200 is configured as a combined component including at least an anti-impact base plate 210 and two anti-impact side plates 220. The anti-impact base plate 210 is elongated, and the anti-impact side plates 220 are elongated, with the two anti-impact side plates 220 bent and disposed on the same side of the anti-impact base plate 210. Both the anti-impact base plate 210 and the two anti-impact side plates 220 extend axially along the condenser body 100, and the two axial ends of the anti-impact base plate 210 and the two anti-impact side plates 220 are respectively connected to the inner walls of the two axial ends of the condenser body 100. The side of the two anti-impact side plates 220 away from the anti-impact base plate 210 is connected to the inner wall of the condenser body 100. Thus, by bending the first anti-impact member 200, its impact resistance is improved.

[0056] See Figure 1 and Figure 3 In one possible implementation, the anti-impact base plate 210 includes a clearance area and an air hole area. The clearance area is provided corresponding to the air intake pipe assembly 300, and multiple air distribution holes 201 are distributed in the air hole area. The air distribution holes 201 closer to the clearance area are smaller in size.

[0057] In this embodiment, the specific configuration of the anti-impact base plate 210 is optimized. Specifically, the anti-impact base plate 210 is configured as a composite structure including at least a clearance zone and a perforated zone. The clearance zone does not have any equalizing vents 201, but two perforated zones are provided, one on each side of the clearance zone. The clearance zone corresponds to the air inlet pipe assembly 300 and is used to ensure the rigidity and strength of the entire anti-impact base plate 210. The two perforated zones are distributed along the axial direction of the condenser body 100 and are used to divert the gas in the buffer chamber to the heat exchange chamber for heat exchange. Multiple equalizing vents 201 are provided on the perforated zones. The perforated vents 201 closer to the clearance zone have smaller diameters, and the perforated vents 201 farther from the clearance zone have larger diameters. This ensures that the gas enters the heat exchange chamber uniformly, achieving heat exchange uniformity and improving heat exchange effect and efficiency.

[0058] See Figure 1 and Figure 3 In one possible implementation, the anti-impact side plate 220 is provided with a connection notch on the side away from the anti-impact bottom plate 210. The connection notch cooperates with the washer so that when the anti-impact side plate 220 is connected to the inner wall of the condenser body 100, the washer presses against the anti-impact side plate 220 and the inner wall of the condenser body 100, thereby improving the connection stability between the first anti-impact member 200 and the condenser body 100.

[0059] In one possible implementation, the first anti-impact member 200 includes a plurality of connected anti-impact units distributed along the axial direction of the condenser body 100. The free ends of the two anti-impact units at both ends are respectively connected to the corresponding axial ends of the condenser body 100, thereby dividing the heat exchange chamber into two functionally independent chambers.

[0060] See Figure 1 In one possible implementation, the condenser body 100 includes a housing 110 and a heat exchange tube assembly 120. A first anti-impact member 200 is disposed inside the housing 110 and divides the housing 110 into a buffer chamber and a heat exchange chamber. An air inlet pipe assembly 300 is inserted into the housing 110 through an air inlet, and the heat exchange tube assembly 120 is disposed in the heat exchange chamber.

[0061] In this embodiment, the specific configuration of the condenser body 100 is optimized. Specifically, the condenser body 100 is configured as a combined component including at least a shell 110 and a heat exchange tube assembly 120. The shell 110 has a heat exchange chamber, and a first anti-impact member 200 is disposed inside the shell 110, dividing the internal space of the shell 110 into a functionally independent buffer chamber and a heat exchange chamber. The high-speed airflow slows down in the buffer chamber and enters the heat exchange chamber through the air distribution holes 201 arranged on the first anti-impact member 200, where it exchanges heat and cools down with the heat exchange tube assembly 120 inside the heat exchange chamber.

[0062] See Figure 1 In one possible implementation, the heat exchange tube assembly 120 includes a plurality of heat exchange tube bodies 121 and a plurality of support members 122. The plurality of heat exchange tube bodies 121 are stacked in the heat exchange chamber and extend along the axial direction of the housing 110. The plurality of support members 122 are spaced apart along the axial direction of the housing 110 in the heat exchange chamber to provide support for the plurality of heat exchange tube bodies 121.

[0063] In this embodiment, the specific configuration of the heat exchanger tube assembly 120 is optimized. Specifically, the heat exchanger tube assembly 120 is configured as a combined component comprising at least a plurality of heat exchanger tube bodies 121 and a plurality of support members 122. The support member 122 can be a vertically arranged vertical support plate, which is connected between the inner wall of the housing 110 and the first anti-impact member 200. The support member 122 has a plurality of fixing holes, and the heat exchanger tube bodies 121 sequentially pass through the corresponding fixing holes on the plurality of support members 122 and are connected and fastened to the plurality of support members 122.

[0064] In one example, the support 122 may also include a transversely arranged transverse support plate that extends axially along the housing 110 and passes through a plurality of vertical support plates, thereby improving the stability of the connection between the plurality of vertical support plates.

[0065] In addition, this application also provides a refrigeration unit, including a throttling unit, an evaporator and a compressor connected in sequence. The refrigeration unit also includes a shell-and-tube condenser as described above. The shell-and-tube condenser is located between the compressor and the throttling unit. The compressor is connected to the pipe body 310 of the inlet pipe assembly 300 of the shell-and-tube condenser. The throttling unit is connected to the liquid outlet of the shell-and-tube condenser to form a refrigerant circulation loop.

[0066] In this embodiment, the specific structure of the shell-and-tube condenser is the same as that in the above embodiments. Since this refrigeration unit adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described in detail here.
