Description

Technical Field

[0001] This utility model relates to the field of condenser technology, and in particular to a gas equalization and liquid blocking device, a horizontal shell and tube condenser, and an air conditioner. Background Technology

[0002] Horizontal shell-and-tube condensers are widely used in the air conditioning and refrigeration industry due to their advantages of high heat transfer efficiency, good scalability, low cost, and ease of maintenance. During operation, gaseous refrigerant enters through the inlet on the shell and exchanges heat with the condenser tubes filled with cooling medium, condensing into liquid refrigerant. The liquid refrigerant then exchanges heat again in the subcooling zone before flowing out through the outlet.

[0003] When a horizontal shell-and-tube condenser is working, gaseous refrigerant enters the shell and is blocked and dispersed by a baffle plate welded and fixed in front of the inlet. During this process, the distribution of gaseous refrigerant is not uniform, with more concentrated around the inlet. The space near the tube sheets on both sides is only gradually filled by gas diffusion. Before complete filling, the contact between the condenser tubes and the gaseous refrigerant is insufficient, and heat exchange cannot achieve the desired effect. The liquid refrigerant produced by condensation on the upper condenser tubes drips and adheres to the lower condenser tubes (this type of liquid refrigerant is called "migrating droplets"), enveloping the fins on the surface of the condenser tubes. This reduces the contact area between the lower condenser tubes and the gaseous refrigerant, thus affecting heat exchange.

[0004] To prevent the liquid refrigerant from entering the lower condenser tube and causing poor heat exchange, adding a sloping baffle between the upper and lower condenser tubes is a low-cost and effective solution. The baffle separates the dripping liquid refrigerant from the lower condenser tube and allows it to flow down from the side due to the slope, thus avoiding affecting the lower condenser tube.

[0005] The applicant has discovered that the prior art has at least the following technical problems: the presence of the baffle prevents the gaseous refrigerant from being evenly distributed from above through the gaps between the condenser tubes. Instead, it can only sink through the gaps formed between the baffle and the shell on both sides. The gaseous refrigerant needs to diffuse from both sides to the middle. The condenser tubes located at the edges are not affected, but the condenser tubes directly below the baffle do not have sufficient contact with the gaseous refrigerant, resulting in an unsatisfactory heat exchange effect in this part. Utility Model Content

[0006] The purpose of this invention is to provide a gas-equalizing liquid-blocking device, a horizontal shell-and-tube condenser, and an air conditioner that can block migrating droplets and prevent uneven distribution of gaseous refrigerant below the baffle. This device can fully subcool the collected migrating droplets, thereby improving the subcooling heat exchange efficiency and solving the technical problem of unreasonable liquid-blocking device structure in the prior art, which affects the heat exchange effect.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] This utility model provides a gas equalization and liquid blocking device, comprising an upper gas equalization plate, a liquid blocking plate, a lower gas equalization plate, and a gas passing assembly; wherein:

[0009] The upper gas distribution plate is arranged at the upper condenser pipe to uniformly diffuse the incoming gaseous refrigerant.

[0010] The baffle plate is positioned below the upper gas equalization plate to block the condensed migrating droplets;

[0011] The lower gas distribution plate is located below the liquid baffle and at the lower condenser pipe, and is used to uniformly diffuse the gaseous refrigerant.

[0012] The gas distribution assembly is disposed between the upper gas distribution plate and the lower gas distribution plate and is used for the delivery of gaseous refrigerant.

[0013] The gas equalization and liquid blocking device provided by this utility model includes an upper gas equalization plate, a liquid blocking plate, a lower gas equalization plate, and a gas passing component. The upper gas equalization plate blocks and disperses the gaseous refrigerant entering through the air inlet, allowing the gaseous refrigerant to fully contact the upper condenser tube for efficient heat exchange. The liquid blocking plate located below the upper gas equalization plate blocks migrating droplets, preventing them from falling onto the lower condenser tube. The gas passing component and the lower gas equalization plate transfer the gaseous refrigerant located at the upper gas equalization plate to the lower gas equalization plate, enabling the gaseous refrigerant entering from the air inlet to sink evenly from above. This allows all parts of the condenser tube to fully participate in heat exchange, while preventing the liquid refrigerant from affecting the lower condenser tube and ensuring that the lower condenser tube can fully contact the gaseous refrigerant for heat exchange.

[0014] Based on the above technical solution, the present invention can be further improved as follows.

[0015] As a further improvement of this utility model, the upper gas equalization plate is provided with a gas gathering groove, and a plurality of first air passage holes are opened in the gas gathering groove; second air passage holes are arranged in an array on the surface of the upper gas equalization plate located on both sides of the gas gathering groove; one end of the air passage component is connected to the first air passage hole.

[0016] As a further improvement of this utility model, the diameter of the first vent hole is much larger than the diameter of the second vent hole.

[0017] The upper gas distribution plate of this utility model is an upper gas distribution plate with a gas gathering groove (recess) folded out in the middle. The upper gas distribution plate has a second gas passage hole (small circular hole) evenly opened on the large surface, which can make the gaseous refrigerant sink evenly. The gas gathering groove (recess) has a first gas passage hole, the size of which is larger than that of the second gas passage hole. A gas passage component (connector) is welded on the large hole and connected to the lower liquid baffle and the lower gas distribution plate. Part of the gaseous refrigerant directly enters the lower gas distribution plate through the gas passage component (connector), so that the condenser tube below the liquid baffle fully contacts the gaseous refrigerant and participates in heat exchange.

[0018] As a further improvement of this utility model, the liquid baffle is U-shaped and includes a bottom plate and two vertical plates on both sides. A third air passage hole is arranged in an array on the two vertical plates. The air passage component passes through the bottom plate and is connected to the lower air distribution plate.

[0019] The baffle plate of this invention can block the migrating droplets above and reduce the tube bundle effect below.

[0020] As a further improvement of this utility model, the width of the base plate is not less than the width of the upper air distribution plate; the length of the base plate is not less than the length of the upper air distribution plate.

[0021] As a further improvement of this utility model, the lower gas distribution plate includes a base plate and a surrounding plate arranged around the base plate, the surrounding plate being connected to the bottom of the liquid baffle plate; a fourth air passage hole is arranged in an array on the base plate; the bottom of the air passage component passes through the liquid baffle plate and enters the space enclosed by the surrounding plate.

[0022] In this invention, the lower gas distribution plate is bent around its perimeter to form a surrounding plate, which is welded to the liquid baffle to restrict the gaseous refrigerant. The lower plate surface has evenly distributed fourth vent holes (small holes) to allow the gaseous refrigerant to diffuse only from below. A portion of the gaseous refrigerant enters the lower gas distribution plate directly through the vent assembly (connector), ensuring full contact between the condenser tube below the liquid baffle and the gaseous refrigerant for heat exchange.

[0023] As a further improvement of this utility model, the width of the substrate is not greater than the width of the baffle plate; the length of the substrate is not greater than the length of the baffle plate.

[0024] As a further improvement of this utility model, it also includes a subcooling component connected to the baffle plate.

[0025] This invention improves the subcooling heat exchange efficiency by connecting a subcooling component to a baffle plate, which blocks migrating droplets, reduces the tube bundle effect below, and further subcools the collected liquid refrigerant before transporting it to the subcooling zone.

[0026] As a further improvement of this utility model, the subcooling assembly includes a drain pipe and a subcooling water container; wherein:

[0027] The drain pipe is connected to the baffle plate to draw out the migrating droplets blocked by the baffle plate;

[0028] The supercooled water container is wrapped around the outside of the drain pipe to cool the migrating droplets using supercooled water.

[0029] As a further improvement of this utility model, heat dissipation fins are provided on the outer side of the drain pipe.

[0030] The subcooling component of this invention enhances heat exchange by cutting heat exchange fins on the outside of the drain pipe, mimicking a heat exchange tube. It is also wrapped with a subcooled water container to introduce subcooled water for heat exchange. The subcooled water container carries subcooled water, which exchanges heat with the refrigerant in the drain pipe for additional subcooling.

[0031] As a further improvement of this utility model, the liquid baffle is also provided with a drainage structure.

[0032] As a further improvement of this utility model, the drainage structure includes a liquid inlet groove and a liquid outlet; wherein:

[0033] The liquid inlet groove is V-shaped and extends along the length of the liquid baffle.

[0034] The surface of the baffle plate is a sloping structure, with the lower end being the side closest to the liquid inlet groove;

[0035] The bottom of the liquid inlet tank is an inclined structure, with the lower end being the side closest to the subcooling component;

[0036] The drain hole is located on one side of the lower end of the liquid inlet tank;

[0037] The subcooling component is connected to the drain hole.

[0038] The baffle plate of this utility model has a certain slope, and the lower part is bent to form a liquid inlet groove. At the end of the liquid inlet groove, there is a subcooling component, which can transport liquid refrigerant to the subcooling zone.

[0039] The present invention provides a condenser, including the gas equalization and liquid blocking device.

[0040] As a further improvement of this utility model, the gas equalization and liquid blocking device is fixed by welding through a support plate assembly.

[0041] As a further improvement of this utility model, the condenser is a horizontal shell-and-tube condenser.

[0042] This invention features a gas-equalizing and liquid-blocking device inside a horizontal shell-and-tube condenser that prevents liquid refrigerant dripping and collects and transports it to the subcooled zone. This device avoids the interference of baffles that could affect the diffusion of gaseous refrigerant and hinder the heat exchange of the lower condenser tubes. The device incorporates a subcooling component, with a subcooled water container outside the drain pipe that carries the collected liquid refrigerant. Subcooled water is introduced into the container and exchanges heat with the liquid refrigerant through fins on the drain pipe surface. This solves the problems caused by the addition of baffles, where the condenser tubes directly below cannot fully contact the gaseous refrigerant, affecting the heat exchange in that area. It also addresses the issue of uneven distribution of the gaseous refrigerant, preventing condenser tubes near the tube sheet from fully participating in heat exchange, further impacting heat exchange efficiency. Furthermore, it resolves the problem of blocked, migrating droplets not being utilized, sliding from the shell edge, and failing to achieve ideal heat exchange in the subcooled zone.

[0043] The present invention provides an air conditioner, including the condenser. Attached Figure Description

[0053] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0054] like Figures 3-7 As shown, this utility model provides a gas equalization and liquid blocking device 200. Specifically, it provides a gas equalization and liquid blocking device 200 applied in a bedroom shell-and-tube condenser. The gas equalization and liquid blocking device 200 includes an upper gas equalization plate 1, a liquid blocking plate 2, and a lower gas equalization plate 3 arranged sequentially; and a gas passing assembly 5; wherein:

[0055] The upper vapor distribution plate 1 is arranged at the upper condenser tube to uniformly diffuse the incoming gaseous refrigerant;

[0056] The baffle plate 2 is positioned below the upper gas equalization plate 1 to block the migrating droplets of condensation;

[0057] The lower gas distribution plate 3 is set below the liquid baffle plate 2 and located at the lower condenser tube, and is used to uniformly diffuse the gaseous refrigerant;

[0058] The gas distribution assembly 5 is disposed between the upper gas distribution plate 1 and the lower gas distribution plate 3, and is used to transport gaseous refrigerant from the upper gas distribution plate 1 to the lower gas distribution plate 3.

[0059] The gas equalization and liquid blocking device 200 provided by this utility model includes an upper gas equalization plate 1, a liquid blocking plate 2, a lower gas equalization plate 3, and a gas passing component 5. The upper gas equalization plate 1 blocks and disperses the gaseous refrigerant entering through the air inlet 100, allowing the gaseous refrigerant to fully contact the upper condenser tube for efficient heat exchange. The liquid blocking plate 2, located below the upper gas equalization plate 1, blocks the migration of dripping liquid, preventing it from falling onto the lower condenser tube. The gas passing component 5 and the lower gas equalization plate 3 transfer the gaseous refrigerant located at the upper gas equalization plate 1 to the lower gas equalization plate 3, enabling the gaseous refrigerant entering from the air inlet 100 to sink evenly from above, allowing all parts of the condenser tube to fully participate in heat exchange. This also prevents the liquid refrigerant from affecting the lower condenser tube while ensuring that the lower condenser tube can fully contact the gaseous refrigerant and participate in heat exchange.

[0060] like Figure 3 and Figure 4 As shown, in an optional embodiment of this utility model, an air-gathering groove 11 is provided on the upper air-equalizing plate 1; further, the air-gathering groove 11 is formed by bending the upper air-equalizing plate 1 through sheet metal, and is located at the middle position in the width direction of the air-gathering groove 11. The air-gathering groove 11 is concave downward. In order to achieve the smooth passage of gaseous refrigerant, in this embodiment, a plurality of first air passage holes 12 are opened in the air-gathering groove 11. All the first air passage holes 12 are spaced apart along the length direction of the air-gathering groove 11, so as to transport gaseous refrigerant at different positions respectively; second air passage holes 13 are arrayed on the surface of the upper air-equalizing plate 1 on both sides of the air-gathering groove 11; in order to ensure that some gaseous refrigerant can be transported, the diameter of the first air passage hole 12 is much larger than the diameter of the second air passage hole 13; here, "much larger" can mean that the diameter of the first air passage hole 12 is at least 3 times the diameter of the second air passage hole 13. One end of the air passage component 5 is connected to the first air passage hole 12. With this structure, a portion of the gaseous refrigerant located at the upper air distribution plate 1 will enter the air passage component 5 through the first air passage hole 12, and then enter the lower air distribution plate 3 through the air passage component 5.

[0061] The upper gas equalization plate 1 of this utility model is an upper gas equalization plate 1 with a gas gathering groove 11 (groove) folded out in the middle. The upper gas equalization plate 1 has a second gas passage hole 13 (small circular hole) evenly opened on the large surface, which can make the gaseous refrigerant sink evenly. The gas gathering groove 11 (groove) has a first gas passage hole 12 opened in it. The first gas passage hole 12 (large hole) is larger than the second gas passage hole 13. A gas passage component 5 (connector) is welded on the large hole and connected to the lower liquid baffle plate 2 and the lower gas equalization plate 3. Part of the gaseous refrigerant directly enters the lower gas equalization plate 3 through the gas passage component 5 (connector), so that the condenser tube below the liquid baffle plate 2 is in full contact with the gaseous refrigerant and participates in heat exchange.

[0062] like Figure 3 and Figure 4As shown, the baffle plate 2 is U-shaped and includes a bottom plate 21 and two vertical plates 22 on both sides. The two vertical plates 22 are provided with a third air passage hole 24 in an array. The air passage component 5 passes through the bottom plate 21 and is connected to the lower air distribution plate 3.

[0063] The gaseous refrigerant entering the baffle plate 2 through the second vent 13 on the upper vent plate 1 will diffuse downwards through the third vent 24; while the migrating liquid droplets will be blocked by the bottom plate 21 of the baffle plate 2, preventing them from entering the lower condenser tube. The baffle plate 2 of this invention can block the migrating liquid droplets from above and reduce the tube bundle effect below.

[0064] As a further improvement of this utility model, the width of the base plate 21 is not less than the width of the upper air distribution plate 1; the length of the base plate 21 is not less than the length of the upper air distribution plate 1.

[0065] This structural design ensures that all the migrating droplets formed on the upper vapor distribution plate 1 enter the baffle plate 2, instead of dripping to the outside and entering the lower condenser tube.

[0066] like Figure 3 and Figure 4 As shown, the lower gas equalization plate 3 includes a base plate 31 and a surrounding plate 32 surrounding the base plate 31. The surrounding plate 32 is connected to the bottom of the liquid baffle plate 2. The base plate 31 is provided with an array of fourth air passage holes 33. The bottom of the air passage component 5 passes through the liquid baffle plate 2 and enters the space enclosed by the surrounding plate 32.

[0067] It should be noted that in this embodiment, the upper gas equalization plate 1, the liquid baffle plate 2, and the lower gas equalization plate 3 can all be formed by multiple bending of sheet metal.

[0068] In this invention, the lower gas equalization plate 3 is bent around its perimeter to form a surrounding plate 32, which is welded to the liquid baffle 2 to restrict the gaseous refrigerant. The lower plate surface has evenly distributed fourth vent holes 33 (small holes) to allow the gaseous refrigerant to diffuse only from below. Part of the gaseous refrigerant enters the lower gas equalization plate 3 directly through the vent assembly 5 (connector), ensuring full contact between the condenser tube below the liquid baffle 2 and the gaseous refrigerant for heat exchange.

[0069] Furthermore, the width of the substrate 31 is not greater than the width of the baffle plate 2; the length of the substrate 31 is not greater than the length of the baffle plate 2.

[0070] The above structural design ensures that the gaseous refrigerant delivered by the gas assembly 5 is evenly diffused at the lower gas distribution plate 3.

[0071] It should be noted that the gas-exploding component 5 includes a connecting pipe.

[0072] like Figures 3-7 As shown, it also includes a subcooling assembly 4 connected to the baffle plate 2.

[0073] This invention improves the subcooling heat exchange efficiency by connecting a subcooling component 4 to the liquid baffle 2, which blocks migrating droplets and reduces the tube bundle effect below, while also subjecting the collected liquid refrigerant to additional subcooling before transporting it to the subcooling zone.

[0074] Specifically, the subcooling component 4 includes a drain pipe 41 and a subcooled water container 42; wherein:

[0075] The drain pipe 41 is connected to the baffle plate 2 to draw out the migrating droplets blocked on the baffle plate 2;

[0076] The supercooled water container 42 is wrapped around the outside of the drain pipe 41 to cool the migrating droplets with supercooled water.

[0077] A subcooled water container 42 is wrapped around the outside of the drain pipe 41. The subcooled water container 42 stores subcooled water, and heat exchange is carried out between the subcooled water and the drain pipe 41 to exchange heat with the liquid refrigerant transported in the drain pipe 41. To increase the heat exchange effect, the inlet 422 of the subcooled water container 42 is located on the outlet side of the drain pipe 41, while the outlet 421 is located at the end away from the outlet side of the drain pipe 41. This forms a flow direction of subcooled water that is opposite to the flow direction of liquid refrigerant, thereby improving the heat exchange effect.

[0078] To further improve heat exchange efficiency, heat dissipation fins (not shown in the attached diagram) can be installed on the outside of the drain pipe 41.

[0079] The subcooling component 4 of this utility model enhances the heat exchange of the subcooling component 4 by cutting heat exchange fins on the outside of the drain pipe 41 to mimic the heat exchange tube. At the same time, it is wrapped by a subcooled water container 42 to introduce subcooled water for heat exchange. The subcooled water container 42 carries subcooled water, and the subcooled water exchanges heat with the refrigerant in the drain pipe 41 to perform additional subcooling.

[0080] As an optional embodiment of this utility model, in order to improve the speed and efficiency of liquid drainage, the baffle plate 2 is also provided with a flow guiding structure.

[0081] Specifically, the drainage structure includes a liquid inlet groove 23 and a liquid outlet 25; wherein:

[0082] The liquid inlet trough 23 is V-shaped and formed by sheet metal bending. It extends along the length of the liquid baffle 2 and is located at one end of the width of the liquid baffle 2.

[0083] The surface of the baffle plate 2 is a sloping structure, with the side closer to the liquid inlet trough 23 being the lowest end; of course, the baffle plate 2 can also be set as an inclined structure, with the side closer to the liquid inlet trough 23 being the lowest end. In this way, the liquid refrigerant entering the baffle plate 2 can quickly converge and flow into the liquid inlet trough 23 under its own gravity under the action of the sloping or inclined structure.

[0084] The bottom of the liquid inlet tank 23 is inclined, with the lower end near the subcooling component 4. This structure allows the liquid refrigerant entering the liquid inlet tank 23 to flow quickly toward one corner of the baffle plate 2 for rapid discharge.

[0085] The drain hole 25 is located on one side of the lower end of the liquid inlet trough 23;

[0086] The subcooling component 4 is connected to the drain hole 25.

[0087] The liquid baffle 2 of this utility model has a certain slope, and the lower part is bent to form a liquid inlet groove 23. At the end of the liquid inlet groove 23, there is a subcooling component 4, which can transport liquid refrigerant to the subcooling zone.

[0088] like Figure 1 and Figure 2 As shown, the present invention provides a condenser including a gas equalization and liquid blocking device 200.

[0089] As a further improvement of this utility model, the gas equalization and liquid blocking device 200 is fixed by welding through the support plate assembly 300.

[0090] like Figure 1 As shown, the support plate assembly 300 consists of several spaced vertical plates used to fix the upper gas equalization plate 1, the liquid baffle plate 2, and the lower gas equalization plate 3, respectively. Figure 1 As shown, the welding positions of the upper air distribution plate 1 and the support plate assembly 300 are as follows: Figure 1 As shown, the welding positions of the lower gas distribution plate 3 and the support plate assembly 300 are as follows: Figure 1 As shown.

[0091] As a further improvement of this utility model, the condenser is a horizontal shell-and-tube condenser.

[0092] In this embodiment, the gas equalization and liquid blocking device 200 includes an upper gas equalization plate 1, a gas passing assembly 5, a liquid blocking plate 2, a subcooling assembly 4, and a lower gas equalization plate 3. The subcooling assembly includes a drain pipe 41 and a subcooled water container 42. The upper gas equalization plate 1 is as follows... Figure 3 The plate undergoes four bends, and a second vent hole 13 and a first vent hole 12 are formed on it. The baffle plate 2 is as shown. Figure 3 and Figure 4As shown, the structure is formed by three bends, resulting in a liquid inlet trough 23 (which collects and transports the liquid refrigerant blocked by the baffle plate 2 to the subcooling assembly 4) and a side plate. Large holes are also formed at positions corresponding to the first vent hole 12 on the upper gas distribution plate 1. Third vent holes 24 are evenly distributed on the side plate. A connecting pipe is welded to the first vent hole 12 and the large hole, connecting it to the upper gas distribution plate 1 and the baffle plate 2. The subcooling assembly 4 is welded and fixed to the drain hole 25 at the end of the liquid inlet trough 23 on the baffle plate 2. The drain pipe 41 is externally wrapped by a subcooled water container 42. The lower gas distribution plate 3 is formed by bending and welding sheet metal parts upwards around its perimeter. Fourth vent holes 33 are evenly distributed at the bottom. The lower gas distribution plate 3 is welded and fixed to the bottom of the baffle plate 2. The upper gas distribution plate 1 can be welded to the top of the support plate assembly 300, and the lower gas distribution plate 3 can pass through the opening in the support plate assembly 300 and be welded and fixed. The gas equalization and liquid blocking device 200 is centrally mounted on the support plate assembly 300, which is installed in the housing at a certain distance from the tube sheet. (During installation, the middle plane of the gas equalization and liquid blocking device 200 coincides with the middle plane of the support plate assembly 300; when the support plate assembly 300 is installed into the condenser, it generally does not directly contact the tube sheet, but maintains a certain distance to reduce the unstable length of the heat exchange tubes).

[0093] In operation, gaseous refrigerant enters through inlet 100 and is blocked by upper gas distribution plate 1. Subsequently, some of the gas is evenly distributed above and sinks through second vent 13, contacting the condenser tubes above baffle plate 2. This ensures that all areas of the condenser tubes can fully participate in heat exchange, improving the heat exchange effect. The liquid refrigerant produced during this process drips onto baffle plate 2, reducing the tube bundle effect caused by migrating droplets on the lower condenser tubes and improving the heat exchange effect. Because baffle plate 2 has a certain slope, the liquid refrigerant flows into liquid inlet tank 23 and is pumped away by subcooling component 4 connected to liquid inlet tank 23, directly transporting it to the lower subcooling zone. This prevents liquid refrigerant from accumulating on baffle plate 2, ensuring uninterrupted refrigerant participation in system circulation. The portion of the gaseous refrigerant passing through second vent 13 that is not condensed by the condenser tubes above baffle plate 2 enters the lower part through third vent 24 on the side plate of baffle plate 2, exchanging heat with the condenser tubes at the lower edge. The remaining gaseous refrigerant that does not pass through the second vent 13 enters through the first vent 12, passes through the vent assembly 5, reaches the lower gas equalization plate 3 from the first vent 12, and leaves through the fourth vent 33 at the bottom of the lower gas equalization plate 3, where it exchanges heat with the condenser tube directly below the baffle plate 2. This solves the problem that the condenser tube cannot fully participate in heat exchange due to the uneven distribution of refrigerant below after the baffle is added.

[0094] The drain hole 25 at the liquid inlet groove 23 on the baffle plate 2 should be located at the same end where there is a gap between the baffle plate inside the baffle assembly and the shell (the baffle assembly is a commonly used structure; one end is welded to the tube sheet without gap, while the other end has a larger gap to allow liquid refrigerant to pass through, such as...). Figure 2The portion indicated by the Chinese text. The gap is far from the condenser refrigerant drain port; liquid refrigerant enters from here, travels a longer distance in the subcooling zone, and achieves sufficient subcooling. After being pumped into the subcooling assembly 4, the liquid refrigerant exchanges heat with the subcooled water in the subcooled water container 42, performing additional subcooling and improving the subcooling heat exchange effect. The subcooled water is separated from the water chamber assembly, enters through the inlet 422, participates in heat exchange, and then leaves through the outlet 421, returning to the water chamber assembly.

[0095] Specifically, the upper part of the gas equalization and liquid blocking device 200 is an upper gas equalization plate 1 with a groove folded out in the middle. The upper gas equalization plate 1 has evenly distributed circular second vent holes 13 on its large flat surface, which can make the gaseous refrigerant sink evenly. The groove has a large-sized first vent hole 12. A connecting pipe is welded to the first vent hole 12 and connected to the lower liquid blocking plate 2 and the lower gas equalization plate 3. The liquid blocking plate 2 blocks the migrating droplets above and reduces the tube bundle effect below. The liquid blocking plate 2 itself has a certain slope, and the lower part is bent to form a liquid guide groove. At the end, there is a subcooling component 4, which can transport liquid refrigerant to the subcooled area. Fins are cut out on the outside of the subcooling component 4 (the fins are to imitate heat exchange tubes to enhance the heat exchange of the subcooling component 4). At the same time, a subcooled water container 42 (the function is to carry subcooled water, and the subcooled water exchanges heat with the refrigerant in the subcooling component 4 for additional subcooling) is wrapped around it and subcooled water is introduced for heat exchange. The lower gas equalization plate 3 is bent upwards around its perimeter and welded to the liquid baffle plate 2, restricting the gaseous refrigerant and allowing it to diffuse only through the fourth vent 33 below. Some of the gaseous refrigerant enters the lower gas equalization plate 3 directly through a connecting pipe, ensuring full contact between the condenser tube below the liquid baffle plate 2 and the gaseous refrigerant, thus participating in heat exchange. The gas equalization and liquid baffle device 200 can be welded and fixed to the support plate assembly 300.

[0096] This invention incorporates a gas-equalizing and liquid-blocking device 200 inside a horizontal shell-and-tube condenser, designed to prevent liquid refrigerant dripping and collect and transport it to the subcooled zone. This device 200 avoids the influence of the baffle plate 2 on the diffusion of gaseous refrigerant and interference with the heat exchange effect of the lower condenser tubes. The device 200 includes a subcooling component 4, and a subcooled water container 42 is designed outside the drain pipe 41 that transports the liquid refrigerant collected by the baffle plate 2. Subcooled water is introduced into the container and exchanges heat with the liquid refrigerant through the fins on the surface of the drain pipe 41. This solves the problems of insufficient contact between the condenser tubes directly below and the gaseous refrigerant after the baffle plate is added, affecting the heat exchange effect in that area, and uneven distribution of the gaseous refrigerant, preventing the condenser tubes near the tube sheet from fully participating in heat exchange, thus affecting the heat exchange effect. It also addresses the issue of blocked migrating droplets not being utilized, sliding from the shell edge, and not participating in the heat exchange in the subcooled zone with an unsatisfactory effect.

[0097] The present invention provides an air conditioner, including the condenser described above.

[0098] The air conditioner provided by this utility model features a condenser with a gas-equalizing and liquid-blocking device that prevents the migration of liquid droplets and avoids uneven distribution of gaseous refrigerant below the baffle. The upper gas-equalizing plate blocks and disperses the gaseous refrigerant entering through the air inlet, allowing it to fully contact the upper condenser tubes for efficient heat exchange. A liquid-blocking plate below the upper gas-equalizing plate prevents the migration of liquid droplets from falling onto the lower condenser tubes. The gaseous refrigerant located at the upper gas-equalizing plate is transferred to the lower gas-equalizing plate via the gas-passing assembly and the lower gas-equalizing plate. This allows the gaseous refrigerant entering from the air inlet to sink evenly from above, ensuring that all parts of the condenser tubes fully participate in heat exchange. Furthermore, while preventing liquid refrigerant from affecting the lower condenser tubes, the lower condenser tubes also ensure sufficient contact with the gaseous refrigerant for heat exchange.
