Description

Technical Field

[0001] This invention relates to the field of refrigeration technology, and in particular to a condenser liquid collection pipe structure and an air conditioner. Background Technology

[0002] The condenser is one of the most important components of an air conditioner, and it mainly consists of the condenser assembly and the liquid collector assembly. The quality of the design of the liquid collector assembly often determines the reliability and performance of an air conditioning system.

[0003] In the prior art, as shown in the appendix Figure 1 The condenser component shown includes a liquid collecting pipe assembly 100 and a first condenser assembly 200; the liquid collecting pipe assembly 100 mainly consists of an inlet pipe 110, a distributor head 120, and capillary tubes 130; wherein, one end of the inlet pipe 110 is connected to a distribution chamber for placing refrigerant, the other end of the inlet pipe 110 is connected to one end of the distributor head 120, the other end of the distributor head 120 is connected to one end of a plurality of capillary tubes 130, and the other ends of the plurality of capillary tubes 130 are connected to the first condenser assembly 200.

[0004] Furthermore, due to the specifications and spatial distribution of the distributor head 120, the length of the capillary tube 130 cannot meet the specifications of each flow path into the first condenser assembly 200, resulting in the capillary tube 130 being either too long or too short. If the capillary tube 130 is too long, it needs to be looped before connecting to the corresponding inlet of the first condenser assembly 200; if the capillary tube 130 is too short, it needs to be connected to the first condenser assembly 200 via a transition tube 140. That is, the other end of each capillary tube is connected to one end of the transition tube 140, and the other end of each transition tube 140 is connected to the corresponding inlet of the first condenser assembly 200.

[0005] Therefore, the refrigerant in the evaporator passes sequentially through the inlet pipe 110, the distributor head 120, the capillary tube 130, and the transition pipe 140, and finally enters the first condenser assembly 200. However, the liquid collection pipe assembly 100 of the condenser in the prior art has the following shortcomings:

[0006] 1. The number of capillary tubes 130 in the liquid collecting tube assembly 100 is relatively large. Each capillary tube 130 can be selected with different lengths according to actual needs. If the length of the capillary tube 130 is too long, it needs to be wound around before connecting to the corresponding inlet of the first condenser assembly 200. However, all the capillary tubes 130 need to be placed in the same fixed placement cavity, which makes it easy for the capillary tubes 130 to get tangled together and difficult to distinguish. This can lead to mis-installation in production and makes it difficult to ensure the correct liquid inlet direction.

[0007] 2. Due to differences in air conditioning airflow and air conditioning space layout, the gas-liquid state and temperature of each path in the first condenser assembly 200 are different. However, the inlet size of the existing first condenser assembly 200 is the same. Therefore, the flow velocity into each path in the first condenser assembly 200 is the same, resulting in the gas-liquid state and temperature of each path in the first condenser assembly 200 being the same. Consequently, the first condenser assembly 200 may experience frosting and poor heat exchange during the heat exchange process.

[0008] 3. The transition tube 140 is welded to the inlet of the first condenser assembly 200, which leads to an increase in the number of weld points and potential problems such as tube grinding between capillary tubes 130. In after-sales maintenance, problems such as weld point leakage and tube grinding of capillary tube 130 are prominent. Summary of the Invention

[0009] In view of this, the present invention provides a condenser liquid collection pipe structure and an air conditioner to solve the problem that in the prior art, the flow rate of each path of the liquid collection pipe structure flowing into the first condenser assembly is the same, and the corresponding flow rate cannot be adjusted according to the gas-liquid state and temperature requirements of each path in the condenser assembly.

[0010] To achieve one or more of the above objectives or other objectives, the technical solution of the present invention is a liquid collecting pipe structure for a condenser, including a liquid collecting plate, wherein at least one liquid distributing device and multiple flow path structures are provided on one side of the interior of the liquid collecting plate.

[0011] One end of the liquid separating device is used to connect to the evaporator, and the other end of the liquid separating device is connected to one end of a plurality of flow path structures. The other ends of the plurality of flow path structures are located on the other side of the liquid collecting plate and are used to connect to the second condenser assembly.

[0012] The flow path structure has multiple dimensions, and each of the dimensions has at least one flow path structure.

[0013] Furthermore, the liquid collection plate is rectangular, and multiple flow path structures are arranged along the length direction of the liquid collection plate, and the lengths of the flow path structures are all different.

[0014] Furthermore, the thickness of the liquid collection plate is greater than 2 mm.

[0015] Furthermore, neither of the two described flow path structures is interconnected.

[0016] Furthermore, the flow path structure is a circular channel, and the diameter of the flow path structure is less than 2 mm.

[0017] Furthermore, each of the flow path structures is provided with a connecting pipe at the end away from the liquid distribution device, and the end of each connecting pipe away from the flow path structure is used to connect to the second condenser assembly.

[0018] Furthermore, the liquid collecting plate is provided with a receiving portion corresponding to the liquid dispensing device, and the thickness of the receiving portion is greater than the thickness of the liquid collecting plate without the receiving portion.

[0019] Furthermore, there are two liquid separation devices, one on the upper part and one on the lower part of one side of the liquid collection plate.

[0020] Furthermore, the liquid collection plate is made of any one of aluminum plate, stainless steel plate, and copper plate.

[0021] An air conditioner includes the liquid collection pipe structure of the condenser described above.

[0022] Compared with the prior art, the present invention has at least the following beneficial effects:

[0023] 1. The present invention controls the flow rate of refrigerant into the second condenser assembly by setting flow path structures of different sizes in the liquid collection plate, thereby precisely controlling the flow rate of refrigerant in the evaporator into each path of the second condenser assembly. This can avoid problems such as frosting and poor heat exchange in the second condenser assembly during the heat exchange process.

[0024] 2. The flow path structures in this invention are all independently set, which reduces the possibility of misinstallation between the flow path structure and each inlet of the second condenser assembly, thereby ensuring the correct liquid inlet direction and enabling the refrigerant in the evaporator to flow into each of the corresponding channels in the second condenser assembly through the flow path structure.

[0025] 3. The present invention can set the length of the flow path structure according to the flow rate of refrigerant flowing into each path in the second condenser assembly. Therefore, the flow path structure will not have the problem of being too short and needing to be extended, thereby reducing the number of solder joints on the second condenser assembly. In addition, the flow path structure does not have the hidden dangers of tube grinding, so it is not easy to have prominent problems such as missing solder joints or tube grinding during after-sales maintenance.

[0049] To make the technical problems, technical solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. Therefore, a feature pointed out in this specification is used to illustrate one feature of one embodiment of the invention, and does not imply that every embodiment of the invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0050] The principles and structure of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0051] In one embodiment, refer to Appendix Figure 2-3 The present invention proposes a liquid collecting pipe structure for a condenser, including a liquid collecting plate 10, wherein at least one liquid distributing device 20 and multiple flow path structures 101 are provided on one side of the interior of the liquid collecting plate 10.

[0052] One end of the liquid separating device 20 is used to connect to the evaporator, and the other end of the liquid separating device 20 is connected to one end of a plurality of flow path structures 101. The other ends of the plurality of flow path structures 101 are located on the other side of the liquid collecting plate 10 and are used to connect to the second condenser assembly 30.

[0053] The flow path structure 101 has multiple sizes, and each size of the flow path structure 101 is provided with at least one; and the flow path structure 101 is a circular pipe.

[0054] The function of the liquid distribution device 20 is as follows: when the refrigerant from the evaporator flows into the liquid distribution device 20, the liquid distribution device 20 then distributes the flowing refrigerant into the corresponding connected flow path structure 101, and then the refrigerant flows into the second condenser assembly 30 through the flow path structure 101.

[0055] When the refrigerant in the evaporator needs to enter the second condenser assembly 30 through the liquid collection pipe structure of the present invention, the gas-liquid state and temperature of each path in the second condenser assembly 30 are different due to the different air conditioning air field and air conditioning space layout. Therefore, the liquid collection pipe structure of the present invention is needed to accurately control the flow rate of the refrigerant in the evaporator into each path in the second condenser assembly 30. This can avoid problems such as frost formation and poor heat exchange during the heat exchange process of the second condenser assembly 30.

[0056] Among them, one of the channels in the second condenser assembly 30 is the corresponding inlet connecting the second condenser assembly 30 to each flow path structure 101, and each inlet is one channel, the same applies throughout the text.

[0057] Furthermore, during the production and assembly of air conditioners, the air conditioner will calculate the required flow rate for each path flowing into the second condenser assembly 30 based on the different air conditioning air field and air conditioning space layout, as well as the preset parameters such as the gas-liquid state and temperature of each path in the second condenser assembly 30. Then, the aperture of the flow path structure 101 will be set according to the calculated flow rate. Therefore, the apertures of all flow path structures 101 are partially the same and partially different.

[0058] Therefore, according to the required flow rate of each path flowing into the second condenser assembly 30, a flow path structure 101 with a corresponding aperture is set on the liquid collection plate 10. In this way, when refrigerant from the evaporator flows into the second condenser assembly 30 through the flow path structure 101, the flow rate of the refrigerant flowing into the second condenser assembly 30 is different at the same time due to the different apertures of the flow path structure 101. This allows for precise control of the flow rate of the refrigerant from the evaporator into each path of the second condenser assembly 30, thus avoiding problems such as frosting and poor heat exchange in the second condenser assembly 30 during the heat exchange process.

[0059] Furthermore, the flow path structure 101 of the present invention avoids the problem in the prior art where the capillary tubes 130 are too long and need to be coiled, and then all the capillary tubes 130 are placed in the same fixed placement cavity, which makes the capillary tubes 130 easy to get tangled and difficult to distinguish. The flow path structure 101 of the present invention is opened in the liquid collection plate 10 according to actual needs, and each flow path structure 101 is independently set. In this way, there is no problem that the capillary tubes 130 are easy to get tangled and difficult to distinguish. This can greatly reduce the situation of misinstallation of the flow path structure 101 and each inlet of the second condenser assembly 30 during the production process, thereby ensuring the correct liquid inlet direction, so that the refrigerant in the evaporator can flow into each of the channels in the second condenser assembly 30 through the flow path structure 101.

[0060] Furthermore, in the existing technology, some inlets of the first condenser assembly 200 are welded with transition tubes 140, which increases the number of weld points on the first condenser assembly 200 and creates potential problems such as tube wear between capillary tubes 130, making it easy for prominent issues such as missing weld points and tube wear to occur during after-sales maintenance. In contrast, the present invention allows the length of the flow path structure 101 within the liquid collection plate 10 to be set according to the flow rate of the refrigerant into the second condenser assembly 30. Therefore, the flow path structure 101 will not be too short and need to be extended, which reduces the number of weld points on the second condenser assembly 30. Moreover, the flow path structure 101 does not have the potential problems of tube wear, so prominent issues such as missing weld points and tube wear are less likely to occur during after-sales maintenance.

[0061] In other embodiments (not shown herein), one end of the liquid separating device 20 is used to connect to other pipeline systems, including high-pressure pipelines, low-pressure pipelines, pipes, expansion valves, etc.

[0062] One end of the liquid separator 20 is connected to the evaporator through another pipeline system, and the other end of the liquid separator 20 is connected to one end of a plurality of flow path structures 101. The other ends of the plurality of flow path structures 101 are located on the other side of the liquid collection plate 10 and are used to connect to the corresponding inlet of the second condenser assembly 30.

[0063] In one embodiment, to further precisely control the flow rate of refrigerant flowing from the evaporator into each path of the second condenser assembly 30, refer to the appendix. Figure 4-5 The liquid collection plate 10 is rectangular, and multiple flow path structures 101 are arranged along the length direction of the liquid collection plate 10, and the lengths of the flow path structures 101 are all different.

[0064] Since the lengths of the flow path structures 101 are different, under the premise of the same flow rate and the same orifice diameter, the shorter the length of the flow path structure 101, the faster the refrigerant can flow into the second condenser assembly 30. Therefore, this can further control the flow rate of the refrigerant in the evaporator into the second condenser assembly 30, thus avoiding problems such as frost formation and poor heat exchange in the second condenser assembly 30 during the heat exchange process.

[0065] Of course, the shape of the liquid collecting plate 10 can also be square or other shapes suitable for arranging the flow path structure 101.

[0066] In one embodiment, the thickness of the liquid collection plate 10 is greater than 2 mm. This ensures that the liquid collection plate 10 is not easily damaged or deformed by impact, allowing the refrigerant to flow normally through the flow path structure 101 within the liquid collection plate 10, thus extending the service life of the liquid collection plate 10 and consequently extending the service life of the air conditioner.

[0067] In one embodiment, refer to Appendix Figure 5Each of the flow path structures 101 is set independently, and no two flow path structures 101 are connected.

[0068] The specific flow path and layout of the flow path structure 101 can be designed according to the actual needs of the second condenser assembly 30. In this way, by simultaneously controlling the aperture and length specifications of the flow path structure 101, the flow rate of the refrigerant flowing into the second condenser assembly 30 from the evaporator can be precisely controlled. Moreover, this structure is simple and inexpensive.

[0069] In one embodiment, the flow path structure 101 is a circular channel, and the diameter of the flow path structure 101 is less than 2 mm.

[0070] This prevents the aperture of the flow path structure 101 from being larger than the thickness of the liquid collection plate 10, and prevents the surface of the liquid collection plate 10 from being uneven, which would affect the aesthetics of the product.

[0071] Of course, the shape of the flow path structure 101 can also be square, elliptical, or other shapes suitable for the smooth flow of refrigerant.

[0072] In one embodiment, refer to Appendix Figure 3-4 Each of the flow path structures 101 is provided with a connecting pipe 102 at the end away from the liquid distribution device 20, and the end of each connecting pipe 102 away from the flow path structure 101 is used to connect to the second condenser assembly 30.

[0073] In this way, the connecting pipe 102 can be sealed and embedded in the inlet of the second condenser assembly 30, which facilitates the connection of the liquid collecting pipe structure of the present invention to the inlet of the second condenser assembly 30 through the connecting pipe 102.

[0074] This reduces the number of solder joints on the second condenser assembly 30, and the flow path structure 101 does not have the hidden dangers of tube grinding, so it is not easy to have prominent problems such as missing solder joints or tube grinding during after-sales maintenance.

[0075] In other embodiments, refer to the appendix Figure 6 Each flow path structure 101, at one end away from the liquid distribution device 20, is directly connected to the corresponding inlet of the second condenser assembly 30. The connection method includes welding or embedding. Embedding involves extending the corresponding inlet of the second condenser assembly 30 outwards and then sealingly embedding it into the end of the corresponding flow path structure 101 away from the liquid distribution device 20.

[0076] In one embodiment, refer to Appendix Figure 2 The liquid collecting plate 10 is provided with a receiving part 103 corresponding to the liquid dispensing device 20. The thickness of the receiving part 103 is greater than the thickness of the liquid collecting plate 10 without the receiving part 103.

[0077] This facilitates the installation of the liquid distribution device 20 in the receiving part 103, and makes it easier to increase the size of the liquid distribution device 20, so that the liquid distribution device 20 can be connected to more flow path structures 101.

[0078] The shape of the liquid separating device 20 is not limited as long as it can perform liquid separation. Since the shape of the receiving part 103 must match the shape of the liquid separating device 20, the shape of the receiving part 103 is also not limited.

[0079] In one embodiment, refer to Appendix Figure 4-5 Preferably, there are two liquid separating devices 20, with one liquid separating device 20 located on the upper and lower parts of one side of the liquid collecting plate 10.

[0080] In this way, the refrigerant in the evaporator can be diverted by the two liquid distribution devices 20, thus flowing into the flow path structure 101 more quickly.

[0081] Specifically, when the air conditioner is turned on and in cooling mode, the refrigerant in the evaporator first flows into two liquid distribution devices 20 respectively. Then, the two liquid distribution devices 20 divide the flowing refrigerant into the corresponding connected flow path structure 101. Then, the refrigerant flows through the flow path structure 101 into the corresponding path in the second condenser assembly 30.

[0082] When the air conditioner is turned on and in heating mode, the refrigerant in each path of the second condenser assembly 30 flows into the corresponding flow path structure 101. Then the refrigerant is collected from the flow path structure 101 into the two liquid distribution devices 20 and fully mixed. The mixed refrigerant then flows into the evaporator from the two liquid distribution devices 20.

[0083] In other embodiments, refer to the appendix Figure 7 Preferably, the liquid distribution device 20 of the air conditioner is one unit, and a liquid distribution device 20 is provided in the middle of one side of the liquid collection plate 10. In this case, the liquid collection pipe structure of the condenser of the present invention is suitable for air conditioners with smaller power and horsepower.

[0084] In this way, when the air conditioner is turned on and in cooling mode, the refrigerant in the evaporator first flows into the liquid distribution device 20, and then the liquid distribution device 20 distributes the flowing refrigerant into the corresponding connected flow path structure 101. Then the refrigerant flows through the flow path structure 101 into the corresponding path in the second condenser assembly 30.

[0085] When the air conditioner is turned on and in heating mode, the refrigerant in each path of the second condenser assembly 30 flows into the corresponding flow path structure 101. Then the refrigerant is collected from the flow path structure 101 into the liquid distribution device 20 and fully mixed. The mixed refrigerant then flows from the liquid distribution device 20 into the evaporator or other piping systems.

[0086] In other embodiments, refer to the appendix Figure 8 Preferably, there are three liquid distribution devices 20, with one liquid distribution device 20 located at the upper, middle, and lower parts of one side of the liquid collection plate 10. In this case, the liquid collection pipe structure of the condenser of the present invention is suitable for air conditioners with larger power and horsepower, because the more liquid distribution devices 20 there are, the more flow path structures 101 they are connected to, which in turn allows the refrigerant to flow into the condenser at a faster speed, thereby enhancing the cooling capacity of the air conditioner.

[0087] In this way, when the air conditioner is turned on and in cooling mode, the refrigerant in the evaporator first flows into the three liquid distribution devices 20 respectively. Then, the three liquid distribution devices 20 divide the flowing refrigerant into the corresponding connected flow path structure 101. Then, the refrigerant flows into the corresponding path in the second condenser assembly 30 through the flow path structure 101.

[0088] When the air conditioner is turned on and in heating mode, the refrigerant in each path of the second condenser assembly 30 flows into the corresponding flow path structure 101. Then the refrigerant is collected from the flow path structure 101 into the three liquid distribution devices 20 and mixed thoroughly. The mixed refrigerant then flows from the three liquid distribution devices 20 into the evaporator or other piping systems.

[0089] In other embodiments (not shown in the figure), the liquid distribution device 20 can be four or more, depending on the power and horsepower of the air conditioner. This is because the more liquid distribution devices 20 there are, the more flow path structures 101 they are connected to, resulting in a larger amount of refrigerant flowing into the condenser, and thus a higher power and horsepower of the air conditioner.

[0090] Commercial air conditioners, in particular, have a large cooling demand, so it is necessary to increase the flow rate of refrigerant flowing into the condenser. Therefore, it is necessary to increase the number of liquid distribution devices 20, and thus increase the number of flow path structures 101 in the air conditioner.

[0091] In one embodiment, the liquid collection plate 10 is made of any one of aluminum plate, stainless steel plate, and copper plate.

[0092] The liquid collecting plate 10 is preferably made of aluminum plate, which makes the liquid collecting plate 10 cost-effective and reduces production costs.

[0093] The present invention also proposes an air conditioner, which includes the liquid collection pipe structure of the condenser described above.

[0094] The refrigerant flow process in the air conditioner proposed in this invention:

[0095] 1. When the air conditioner is in cooling mode, the refrigerant in the evaporator or other piping system first flows into the liquid distribution device 20, and then the refrigerant is divided in the liquid distribution device 20 into the corresponding flow path structure 101. Then the refrigerant flows into the corresponding path in the second condenser assembly 30 through the flow path structure 101, thereby achieving cooling.

[0096] Second, when the air conditioner is in heating mode, the flow direction of the refrigerant is opposite to that in cooling mode. That is, each path of the refrigerant in the second condenser assembly 30 flows into the corresponding flow path structure 101. Then, the refrigerant in the flow path structure 101 is collected into the corresponding liquid distribution device 20 and fully mixed. Then, the mixed refrigerant flows from the liquid distribution device 20 into the evaporator or other piping system, thereby achieving heating.
