Description

Technical Field

[0001] The present disclosure relates to the technical field of heat exchange equipment, and particularly relates to a nozzle assembly, a heat exchange equipment and a processing method of the nozzle assembly. Background Art

[0002] Spraying and cooling a condenser through a nozzle element to ensure that the heat exchange equipment can operate normally under high ambient temperature is one of the important means to improve the energy efficiency of the heat exchange equipment.

[0003] In the related art, an integrally formed nozzle element is obtained by mechanical cutting. The drill bit needs to be positioned and extended into the liquid inlet cavity and then cut the nozzle with a relatively small size.

[0004] In the above processing method, since the drill bit needs to extend into the liquid inlet cavity, the required length of the drill bit is relatively long. To avoid the drill bit from breaking due to stress, a drill bit with a relatively large diameter is mostly used, and thus the diameter of the processed nozzle is relatively large. The jet flow rate of the nozzle with a relatively large diameter is relatively large, and it is difficult for the sprayed liquid to completely evaporate during the operation of the heat exchange equipment, resulting in a large waste of the sprayed liquid. Summary of the Invention

[0037] To make the objectives, technical solutions, and advantages of the present disclosure clearer, the following will further describe the embodiments of the present disclosure in detail with reference to the accompanying drawings.

[0038] I. Nozzle Assembly

[0039] An embodiment of the first aspect of the present disclosure provides a nozzle assembly. Figure 1 It is a schematic cross-sectional view of a nozzle assembly provided by an embodiment of the present disclosure. Referring to Figure 1 as shown, the nozzle assembly may include a liquid inlet pipe 1, a nozzle 2, and a nozzle cap 3.

[0040] The following will introduce each component of the nozzle assembly separately:

[0041] 1. Liquid inlet pipe 1

[0042] In some embodiments, the liquid inlet pipe 1 has a tubular structure, and the spraying liquid can flow from the tubular structure of the liquid inlet pipe 1 to the nozzle 2.

[0043] The present disclosure does not specifically limit the diameter of the tubular structure of the liquid inlet pipe 1. The diameter of the tubular structure of the liquid inlet pipe 1 can be matched and set according to the requirements of the flow rate and pressure of the spraying liquid. The present disclosure does not specifically limit the shape of the tubular structure of the liquid inlet pipe 1. The tubular structure of the liquid inlet pipe 1 can be a circular pipe structure, and the tubular structure of the liquid inlet pipe 1 can also be other structures such as a square pipe, a triangular pipe, or a polygonal pipe. Without special instructions, the tubular structure of the liquid inlet pipe 1 is taken as an example of a circular pipe structure for illustration, and other cases are similar and will not be elaborated.

[0044] The present disclosure does not specifically limit the shape of the outer wall of the liquid inlet pipe 1, which can be matched and set according to different usage scenarios of the nozzle assembly.

[0045] Referring to Figure 3 as shown, Figure 3 it is a schematic cross-sectional view of a liquid inlet pipe 1 provided by an embodiment of the present disclosure. The outer wall of the liquid inlet pipe 1 may have a connecting portion 14, and the connecting portion 14 is connected to other components of the heat exchange device to increase the mechanical strength of the connection between the nozzle assembly and the heat exchange device.

[0046] The present disclosure does not specifically limit the structure of the connecting portion 14. The connecting portion 14 may have a wavy edge to be connected to other components of the heat exchange device. The connecting portion 14 may also have through holes and be connected to other components of the heat exchange device by screws. The connecting portion may also have a buckle and be connected to other components of the heat exchange device by a buckle and a card slot.

[0047] The outer wall of the liquid inlet pipe 1 may also have a first region 15. The diameter of the first region 15 is different from that of other regions of the outer wall of the liquid inlet pipe 1. The diameter of the first region 15 is adapted to the diameter of the delivery pipe (not shown in the drawings) connected to the liquid inlet pipe 1. The first region 15 may further include a protrusion 151. The protrusion 151 can increase the friction between the outer wall of the liquid inlet pipe 1 and the inner wall of the delivery pipe, preventing the liquid inlet pipe 1 from falling off the inner wall of the delivery pipe, and thus preventing the spraying liquid from entering the nozzle assembly.

[0048] The present disclosure does not specifically limit the number and size of the protrusions 151, which can be matched and set according to factors such as the material of the delivery pipe and the inner wall diameter.

[0049] In some embodiments, referring to Figure 3 As shown, the inner wall of the liquid inlet pipe 1 has a first groove structure 12. The first groove structure 12 on the inner wall of the liquid inlet pipe 1 can be adapted to the first protrusion structure 24 on the outer wall of the nozzle 2. The cooperation between the first groove structure 12 and the first protrusion structure 24 can increase the mechanical strength of the connection between the liquid inlet pipe 1 and the nozzle 2 obtained by the injection molding process, preventing the nozzle 2 from falling off the tubular structure of the liquid inlet pipe 1 under the influence of factors such as the impact of the spraying liquid, and thus preventing the nozzle assembly from failing.

[0050] The present disclosure does not specifically limit the number of the first groove structures 12. It can be one or more, and can be matched and set according to factors such as the size and shape of the area where the inner wall of the liquid inlet pipe 1 is connected to the outer wall of the nozzle 2.

[0051] Based on the same principle, in some other embodiments (not shown in the drawings), the inner wall of the liquid inlet pipe 1 has a protrusion structure, and the protrusion structure on the inner wall of the liquid inlet pipe 1 is adapted to the groove structure on the outer wall of the nozzle 2. This solution has the same advantages as the above embodiments and will not be elaborated here.

[0052] In some embodiments, referring to Figure 3 As shown, the liquid inlet pipe 1 has a boss structure 13. The boss structure 13 is located at one end of the liquid inlet pipe 1 and in the area where the liquid inlet pipe 1 is connected to the nozzle cap 3. After the liquid inlet pipe 1 and the nozzle cap 3 are processed by the fusion welding process, the boss structure 13 is connected to the liquid inlet pipe 1 and the nozzle cap 3 respectively. The boss structure 13 can enhance the mechanical strength of the connection between the liquid inlet pipe 1 and the nozzle cap 3.

[0053] 2. Nozzle 2

[0054] In some embodiments, referring to Figure 4 As shown, Figure 4It is a schematic cross-sectional view of a nozzle 2 provided by an embodiment of the present disclosure. The nozzle 2 has a first end 21, a second end 22, and a transition portion 23. The second end 22 has a nozzle opening 221. The transition portion 23 is located between the first end 21 and the second end 22. The inner diameter of the nozzle 2 gradually decreases from the first end 21 to the transition portion 23, and remains unchanged from the transition portion 23 to the second end 22.

[0055] The spraying liquid flows from the first end 21 to the second end 22 of the nozzle 2. The inner diameter of the nozzle 2 gradually decreases from the first end 21 to the transition portion 23, and the flow rate of the spraying liquid at the transition portion 23 is greater than that at the first end 21; the inner diameter of the nozzle 2 remains unchanged from the transition portion 23 to the second end 22, that is, the inner diameter from the transition portion 23 to the nozzle opening 221 remains unchanged, and the flow rate of the spraying liquid at the nozzle opening 221 of the second end 22 is equal to that at the transition portion 23.

[0056] The gradual decrease in the inner diameter of the nozzle 2 from the first end 21 to the transition portion 23 can also prevent the local area of the inner wall of the nozzle 2 from being subjected to a large impact force of the spraying liquid due to the rapid change in the inner diameter, thereby avoiding adverse phenomena such as wear or cracks on the inner wall of the nozzle 2.

[0057] The present disclosure does not specifically limit the shape of the tubular structure of the nozzle 2. The tubular structure of the nozzle 2 can be a circular tube structure, or can also be other structures such as a square tube, a triangular tube, an elliptical tube, etc. Without special instructions, the tubular structure of the nozzle 2 is taken as an example of a circular tube structure for description, and other situations are similar and will not be elaborated.

[0058] The present disclosure does not specifically limit the diameter size of the nozzle opening 221, which can be matched and set according to the requirements of different heat exchange devices for the flow rate of the spraying liquid. The present disclosure does not specifically limit the shape of the nozzle opening 221, and the nozzle opening 221 can be a round hole, a square hole, a triangular hole, etc.

[0059] In some embodiments, the material of the nozzle 2 is ceramic or metal. The material of the nozzle 2 is preferably ceramic. The ceramic is fired by an advanced production process and then obtained by mechanical processing to obtain the nozzle 2. The ceramic has the advantages of high toughness and high wear resistance, and can be processed to obtain a nozzle 2 with a smaller diameter nozzle opening 221. In the related art, the minimum value of the diameter of the nozzle opening 221 is usually 1.2 mm. The diameter of the nozzle opening 221 of the ceramic nozzle 2 obtained by this solution through mechanical processing can be 0.6 - 0.8 mm. The reduction in the diameter of the nozzle opening 221 of the nozzle 2 can reduce the jet flow rate of the nozzle opening 221, ensuring that the sprayed liquid can evaporate more fully when contacting the relevant components (such as condensers) of the heat exchange device, and avoiding the waste of the sprayed liquid.

[0060] 3. Relationship between the nozzle 2 and the liquid inlet pipe 1

[0061] In some embodiments, referring to Figure 5 as shown, the nozzle 2 has a tubular structure. The nozzle 2 is located inside the tubular structure of the liquid inlet pipe 1 and is connected to the liquid inlet pipe 1. The spraying liquid can move from the tubular structure of the liquid inlet pipe 1 to the first end 21 of the nozzle 2, and then move from the tubular structure of the nozzle 2 to the second end 22 of the nozzle 2 and be sprayed from the nozzle orifice 221 at the second end 22 of the nozzle 2 onto the nozzle cap 3. The diameter of the nozzle orifice 221 at the second end 22 of the nozzle 2 is smaller than the inner wall diameter of the liquid inlet pipe 1, achieving the effect of increasing the flow rate of the spraying liquid.

[0062] In some embodiments, referring to Figure 5 as shown, Figure 5 is an assembly schematic diagram of the liquid inlet pipe 1 and the nozzle 2 provided by an embodiment of the present disclosure. The second end 22 of the nozzle 2 is flush with one end of the liquid inlet pipe 1. On the one hand, the second end 22 of the nozzle 2 being flush with one end of the liquid inlet pipe 1 can simplify the structure of the first mold 4 and reduce the difficulty of the injection molding process; on the other hand, the second end 22 of the nozzle 2 being flush with one end of the liquid inlet pipe 1 can also avoid the nozzle 2 being collided, rubbed, etc. due to the relative movement before the subsequent welding process of the liquid inlet pipe 1 and the nozzle cap 3, thereby affecting the accuracy at the nozzle orifice 221 of the nozzle 2 and further affecting the spraying effect of the nozzle assembly.

[0063] In some embodiments, the outer wall of the nozzle 2 has a first protrusion structure 24, and the inner wall of the liquid inlet pipe 1 has a first groove structure 12. The first protrusion structure 24 on the outer wall of the nozzle 2 can be adapted to the first groove structure 12 on the inner wall of the liquid inlet pipe 1. The cooperation between the first groove structure 12 and the first protrusion structure 24 can increase the mechanical strength of the connection between the liquid inlet pipe 1 and the nozzle 2 obtained by the injection molding process, and avoid the nozzle 2 falling off from the tubular structure of the liquid inlet pipe 1 under the influence of factors such as the impact of the spraying liquid, thereby causing the failure of the nozzle assembly.

[0064] The present disclosure does not make a specific limitation on the number of the first protrusion structures 24. It can be one or more, and can be matched and set according to factors such as the size and shape of the connected area between the inner wall of the liquid inlet pipe 1 and the outer wall of the nozzle 2. The number of the first protrusion structures 24 is adapted to the number of the first groove structures 12.

[0065] Based on the same principle, in some other embodiments, the outer wall of the nozzle 2 has a second groove structure, and the inner wall of the liquid inlet pipe 1 has a second protrusion structure. The second groove structure on the outer wall of the nozzle 2 is adapted to the second protrusion structure on the inner wall of the liquid inlet pipe 1. The second groove structure and the second protrusion structure are not shown in the drawings. This solution has the same advantages as the above embodiments and will not be elaborated here.

[0066] Based on the same principle, in some other embodiments (not shown in the drawings), the outer wall of the nozzle 2 simultaneously has a second groove structure and a first protrusion structure 24, and the inner wall of the liquid inlet pipe 1 also simultaneously has a first groove structure 12 and a second protrusion structure. At this time, the first groove structure 12 on the outer wall of the nozzle 2 is adapted to the first protrusion structure 24 on the inner wall of the liquid inlet pipe 1, and the second protrusion structure on the outer wall of the nozzle 2 is adapted to the second groove structure on the inner wall of the liquid inlet pipe 1. The structure formed by the cooperation of the multiple first groove structures 12 and the first protrusion structures 24 and the multiple second protrusion structures and the second groove structures can further increase the mechanical strength of the connection between the liquid inlet pipe 1 and the nozzle 2 obtained by the injection molding process.

[0067] 4. Nozzle cap 3

[0068] In some embodiments, the nozzle cap 3 is located at one end of the liquid inlet pipe 1 and is connected to the liquid inlet pipe 1. The nozzle cap 3 has a notch portion 32, and the notch portion 32 faces the nozzle 2.

[0069] The notch portion 32 can change the flow direction of the spraying liquid ejected from the second end 22 of the nozzle 2 and form a certain spraying shape, which is beneficial to increasing the contact area between the spraying liquid and the relevant working elements (such as: condenser) in the heat exchange device, improving the utilization efficiency of the spraying liquid, and avoiding the waste of the spraying liquid.

[0070] The present disclosure does not specifically limit the shape of the notch portion 32, and it can be matched and set according to the shape requirements of the spraying liquid ejected by the spraying component for different heat exchange devices. The cross-section of the notch portion 32 along the connection direction of the nozzle cap 3 and the liquid inlet pipe 1 can be fan-shaped, so that the spraying liquid ejected from the nozzle 221 of the nozzle 2 can form a fan-shaped structure, increasing the contact area between the spraying liquid and the temperature adjustment element in the heat exchange device, improving the utilization efficiency of the spraying liquid, and avoiding the waste of the spraying liquid.

[0071] 5. Relationship between the nozzle cap 3 and the liquid inlet pipe 1

[0072] In some embodiments, the liquid inlet pipe 1 has a first positioning structure 11, and the nozzle cap 3 has a second positioning structure 31, and the second positioning structure 31 is adapted to the first positioning structure 11. The cooperation of the first positioning structure 11 and the second positioning structure 31 is convenient for improving the accuracy of the placement positions of the liquid inlet pipe 1 and the nozzle cap 3 before the welding process, avoiding relative movement between the nozzle cap 3 and the liquid inlet pipe 1, and causing the connected area between the nozzle cap 3 and the liquid inlet pipe 1 to block the nozzle 221 of the nozzle 2, thereby resulting in the spraying liquid not being able to be ejected from the nozzle 221, causing the failure or scrapping of the nozzle assembly.

[0073] The present disclosure does not specifically limit the shapes of the first positioning structure 11 and the second positioning structure 31. The first positioning structure 11 and the second positioning structure 31 can be in the form of a protrusion and a groove in cooperation, or in the form of a buckle and a card slot in cooperation or other forms of positioning structures.

[0074] In some embodiments, the first positioning structure 11 is a groove, and the second positioning structure 31 is a protrusion. The first positioning structure 11 and the second positioning structure 31 are inserted into each other. The first positioning structure 11 is located at one end of the liquid inlet pipe 1, and the second positioning structure 31 is located at one section of the nozzle cap 3. The first positioning structure 11 and the second positioning structure 31 face each other, and the two are inserted into each other to realize the positioning cooperation between the liquid inlet pipe 1 and the nozzle cap 3. This positioning cooperation method is simple, which is convenient for the assembly work of the liquid inlet pipe 1 and the nozzle cap 3 during the welding process, and improves the overall processing efficiency of the nozzle assembly.

[0075] The present disclosure does not specifically limit the shapes of the protrusion and the groove, which can be a cylindrical protrusion and a cylindrical groove, or other shapes such as a rectangular protrusion and a rectangular groove, a semi-circular protrusion and a semi-circular groove, etc. Without special instructions, the cylindrical protrusion and the cylindrical groove are taken as an example for description, and other situations are similar and will not be elaborated.

[0076] In some other embodiments, the first positioning structure 11 is a protrusion, and the second positioning structure 31 is a groove; the first positioning structure 11 and the second positioning structure 31 are inserted into each other. This solution has the same advantages as the above embodiments and will not be elaborated here.

[0077] The present disclosure does not specifically limit the number of the first positioning structures 11. The number of the first positioning structures 11 can be one or more, and multiple means two or more. In the embodiments where the number of the first positioning structures 11 is multiple, the multiple first positioning structures 11 are arranged at intervals in the connected area between the liquid inlet pipe 1 and the nozzle cap 3. The multiple first positioning structures 11 can be evenly spaced (e.g., arranged in an array) or unevenly spaced in the connected area between the liquid inlet pipe 1 and the nozzle cap 3.

[0078] The present disclosure does not specifically limit the number of the second positioning structures 31. The number of the second positioning structures 31 can also be one or more. The second positioning structures 31 and the first positioning structures 11 are arranged in one-to-one correspondence. The second positioning structures 31 cooperate with the corresponding first positioning structures 11 to jointly position the liquid inlet pipe 1 and the nozzle cap 3, improving the positioning accuracy of the liquid inlet pipe 1 and the nozzle cap 3.

[0079] II. Heat exchange equipment

[0080] Based on the same concept, the embodiments of the second aspect of the present disclosure provide a heat exchange equipment, which may include a condenser and a nozzle assembly as described in any one of the above embodiments. The nozzle assembly is used to spray a spray liquid onto the condenser. The spray liquid contacts the condenser, and the spray liquid evaporates and absorbs heat, so as to cool the contacted condenser and achieve the effect of adjusting the temperature of the condenser.

[0081] The heat exchange equipment can be a household air conditioner, a central air conditioner, a multi-connected unit heat exchanger, etc. The condenser is a component in the heat exchange equipment. During the normal operation of the condenser, heat is released, so that the temperature of the condenser is relatively high. When the temperature of the condenser is too high, the protection mechanism of the condenser is activated, and the condenser stops working. In this solution, the nozzle assembly sprays liquid onto the condenser, thereby reducing the temperature of the condenser, so that the condenser can continue to work normally.

[0082] In some special cases, when the condenser needs to be heated up to resume normal operation, the nozzle assembly can also spray liquid with a higher temperature onto the condenser to increase the temperature of the condenser, so that the condenser can work normally at a lower ambient temperature.

[0083] The present disclosure does not specifically limit the sprayed liquid. The sprayed liquid can be water, ammonia, freon, etc., and can be specifically selected according to the heat exchange requirements of the condenser in different heat exchange equipment.

[0084] III. Processing method of the nozzle assembly

[0085] An embodiment of the third aspect of the present disclosure provides a processing method of a nozzle assembly. Referring to Figure 7 as shown, Figure 7 is a schematic flow chart of a processing method of a nozzle assembly provided by an embodiment of the present disclosure. The processing method of the nozzle assembly may include:

[0086] Step S100, obtaining the nozzle 2 through machining. The nozzle 2 has a tubular structure.

[0087] The nozzle 2 in step S100 can be machined separately. The diameter of the tubular structure of the nozzle 2 can be further reduced. In particular, the diameter of the nozzle opening 221 at the second end 22 can be further reduced. When the nozzle 2 is made of ceramic material, machining the relatively small nozzle opening 221 is not likely to generate waste residues remaining at the nozzle opening 221, thereby affecting the accuracy of the nozzle opening 221. While ensuring the accuracy requirements, reducing the diameter at the nozzle opening 221 can reduce the jet flow rate of the nozzle opening 221, ensuring that the sprayed liquid can evaporate more fully in the heat exchange equipment and avoiding waste of the sprayed liquid.

[0088] Step S200, fixing the nozzle 2 in the first mold 4.

[0089] Referring to Figure 6 as shown, Figure 6It is a schematic structural diagram of a first mold 4 provided by an embodiment of the present disclosure. The first mold 4 includes a first sub-mold 41 and a second sub-mold 42. The first sub-mold 41 has a limiting structure 4a, and the limiting structure 4a is adapted to the inner wall of the tubular structure of the nozzle 2, that is, the size of the outer wall of the limiting structure 4a is adapted to the size of the nozzle 221 at the second end 22 of the nozzle 2. The limiting structure 4a is inserted into the tubular structure of the nozzle 2, and the second end 22 of the nozzle 2 is in contact with the inner wall of the first mold, thereby playing a role in limiting the nozzle 2 and preventing the nozzle from moving relative to the first mold 4 during the injection molding process in the subsequent step S300.

[0090] Step S300: Based on the first mold 4 fixed with the nozzle 2, injection molding is carried out to obtain a liquid inlet pipe 1 connected with the nozzle 2. The liquid inlet pipe 1 has a tubular structure, and the nozzle 2 is located inside the tubular structure of the liquid inlet pipe 1.

[0091] The first sub-mold 41 has an injection molding pipe 4b. The injection molding pipe 4b is a tubular structure. One end of the injection molding pipe 4b is connected to the inner wall of the first sub-mold 41, and the other end of the injection molding pipe 4b is connected to the outer wall of the first sub-mold 41. The plastic raw material enters the closed space formed by the first sub-mold 41 and the second sub-mold 42 along the injection molding pipe 4b from the outer wall of the first sub-mold 41, thereby obtaining a liquid inlet pipe 1 with a preset shape.

[0092] The present disclosure does not specifically limit the shape, size, and quantity of the injection molding pipe 4b, which can be matched and set according to the amount of plastic raw material required for the liquid inlet pipe 1 in different application environments. The present disclosure does not specifically limit the position of the injection molding pipe 4b. The injection molding pipe 4b can be located in the first sub-mold 41, or the injection molding pipe 4b can also be located in the second sub-mold 42.

[0093] In step S300, the liquid inlet pipe 1 is connected to the nozzle 2 by an injection molding process, ensuring the sealing between the liquid inlet pipe 1 and the nozzle 2 and preventing the sprayed liquid from leaking out from the connected area between the liquid inlet pipe 1 and the nozzle 2, thereby causing waste of the sprayed liquid.

[0094] Step S400: Based on the second mold, injection molding is carried out to obtain a nozzle cap 3.

[0095] Step S500: The nozzle cap 3 is connected to one end of the liquid inlet pipe 1 through a welding process.

[0096] In step S500, the nozzle cap 3 and the liquid inlet pipe 1 are positioned and fixed by inserting and connecting through a first positioning structure 11 and a second positioning structure 31, and a hot melting device (such as an ultrasonic hot melting machine) works to weld and connect the nozzle cap 3 and one end of the liquid inlet pipe 1.

[0097] In step S300 and step S400, the liquid inlet pipe 1 and the nozzle cap 3 made of plastic material are obtained through injection molding process, and in step S500, the two are connected by a fusion welding process. However, the present disclosure is not limited thereto.
