Description

Technical Field

[0001] The present application belongs to the field of refrigeration technology, and in particular relates to an evaporator and a storage device. Background Art

[0002] A blown-type evaporator is constructed from a double-layer aluminum composite. Typically, aluminum sheets of a specified specification are surface-treated, and a pattern of the evaporation tube is printed on the mating surfaces. The composite panels are then welded according to the pattern, subjected to heat treatments such as hot rolling, and finally inflated with nitrogen. Currently, because the inner diameter of the capillary tube outlet is much smaller than the inlet of the evaporator tube, the refrigerant experiences a sudden change in volume when entering the evaporator tube. This results in a rapid drop in pressure, causing a phase change in the refrigerant at the junction of the capillary tube and the evaporator tube, generating a large number of bubbles. These bubbles grow larger as the pressure decreases, eventually bursting and producing a bursting noise. Furthermore, the larger the bubble volume, the greater the bursting noise, impacting the user experience. Summary of the Invention

[0003] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes an evaporator and storage device, which, by disposing a noise reduction tube assembly between the capillary tube and the evaporation tube, wherein the inner diameter of the noise reduction tube is larger than the outer diameter of the capillary tube and smaller than the inner diameter of the evaporation tube, makes the refrigerant flow from the capillary tube to the evaporation tube smoother, reduces the airflow noise caused by rapid changes in pressure and flow rate, and makes the overall operation of the evaporator more stable. This not only increases the service life of the system, but also reduces maintenance and operating costs, and improves the user experience.

[0040] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0041] Reference below Figure 1-Figure 3 The evaporator provided in an embodiment of the present application is described. The evaporator includes a substrate 100 , an evaporation tube 200 , a capillary tube 300 and a noise reduction tube assembly 500 .

[0042] The base plate 100 provides a stable mounting location and is made of metal or other sturdy materials to ensure it can withstand the weight of the evaporation tube 200, capillary tube 300, and noise reduction tube, as well as the vibration and temperature fluctuations experienced during operation. It should be noted that the size and shape of the base plate 100 can be designed based on actual needs and are not specifically limited in this embodiment.

[0043] The evaporation tube 200 is disposed on the substrate 100. The outlet of the evaporation tube 200 is used to connect to the outside world (such as the inlet of the compressor). It should be noted that the specific size and shape of the evaporation tube 200 can be designed according to actual needs and is not specifically limited in this embodiment.

[0044] In this embodiment, the evaporation tube 200 is obtained by inflation molding the substrate 100, that is, the evaporator is an inflation evaporator, which not only improves the heat exchange efficiency, but also helps to reduce noise and vibration because the evaporation tube 200 is closely attached to the substrate 100, thereby improving the stability and service life of the entire evaporator.

[0045] It is understood that the evaporator tube 200 is used to convert the liquid refrigerant into a gaseous state. Specifically, the refrigerant absorbs heat and evaporates within the evaporator tube 200, and then enters the compressor for the next cycle. The evaporator tube 200 can be disposed on only one side of the substrate 100, or on both sides of the substrate 100. This embodiment does not impose any specific limitations on this.

[0046] It should be noted that refrigerants include but are not limited to ammonia (NH3), chlorofluorocarbons (CFCs), hydrogen fluoride (HCFCs), hydrofluorocarbons, hydrofluorocarbons (HFCs), alkanes (HCs) and water.

[0047] The capillary tube 300 is disposed on the substrate 100. The inlet end of the capillary tube 300 is connected to the outside world (e.g., the outlet end of the compressor). Connection methods between the capillary tube 300 and the substrate 100 include, but are not limited to, gluing, welding, or threading. It should be noted that the specific size and shape of the capillary tube 300 can be designed according to actual needs and are not specifically limited in this embodiment.

[0048] It can be understood that since the outer diameter of the capillary tube 300 is much smaller than the inner diameter of the evaporator tube 200, it can play a throttling role. In addition, the inlet end of the capillary tube 300 is connected to the outlet end of the compressor, which can adjust the refrigerant state to a low-pressure state and achieve precise control of the refrigerant flow.

[0049] The noise reduction tube assembly 500 is disposed on the substrate 100. The inlet end of the noise reduction tube assembly 500 is connected to the outlet end of the capillary tube 300, and the outlet end of the noise reduction tube assembly 500 is connected to the inlet end of the evaporation tube 200. The inner diameter of the noise reduction tube assembly 500 is larger than the outer diameter of the capillary tube 300, and the outer diameter of the noise reduction tube assembly 500 is smaller than the inner diameter of the evaporation tube 200. Connection methods between the noise reduction tube assembly 500 and the substrate 100 include, but are not limited to, gluing, welding, or threaded connections. It should be noted that the specific size and shape of the noise reduction tube assembly 500 can be designed according to actual needs and are not specifically limited in this embodiment.

[0050] It can be understood that the refrigerant flows out through the outlet of the compressor and sequentially passes through the capillary tube 300, the noise reduction pipe assembly 500 and the evaporating pipe 200, and then returns to the compressor from the inlet of the compressor to form a heat dissipation loop. Since the inner diameter of the noise reduction pipe assembly 500 is greater than the outer diameter of the capillary tube 300, it helps to reduce the turbulence and impact sound generated by the refrigerant when flowing through; at the same time, the outer diameter of the noise reduction pipe assembly 500 is smaller than the inner diameter of the evaporating pipe 200, which ensures that the refrigerant can smoothly flow into the evaporating pipe 200 and will not be blocked due to the size change of the capillary tube 300 and the noise reduction pipe assembly 500, so that the process of the refrigerant flowing from the capillary tube 300 to the evaporating pipe 200 is more smooth, the airflow noise caused by the rapid change of pressure and flow rate is reduced, and the overall operation of the evaporator is more stable, which not only improves the service life of the system, but also reduces the maintenance cost and operation cost, and improves the user experience.

[0051] According to the evaporator provided by the embodiment of the present application, by arranging the noise reduction pipe assembly 500 between the capillary tube 300 and the evaporating pipe 200, and the inner diameter of the noise reduction pipe being greater than the outer diameter of the capillary tube 300 and smaller than the inner diameter of the evaporating pipe 200, the process of the refrigerant flowing from the capillary tube 300 to the evaporating pipe 200 is more smooth, the airflow noise caused by the rapid change of pressure and flow rate is reduced, and the overall operation of the evaporator is more stable, which not only improves the service life of the system, but also reduces the maintenance cost and operation cost, and improves the user experience.

[0052] In some embodiments, as shown in Figure 3 The noise reduction pipe assembly 500 includes at least two transition pipe segments 510 and at least one throttling pipe segment 520, the inner diameter of the transition pipe segment 510 is greater than the outer diameter of the capillary tube 300, and the outer diameter of the transition pipe segment 510 is smaller than the inner diameter of the evaporating pipe 200, two of the at least two transition pipe segments 510 are respectively connected with the capillary tube 300 and the evaporating pipe 200; two adjacent transition pipe segments 510 are connected through a throttling pipe segment 520, and the outer diameter of the throttling pipe segment 520 is smaller than the inner diameter of the transition pipe segment 510. The connection mode between the transition pipe segment 510 and the throttling pipe segment 520 includes but is not limited to gluing, welding or threaded connection. It should be noted that the specific size and shape of the transition pipe segment 510 and the throttling pipe segment 520 can be designed according to actual needs, and the embodiment does not make specific limitation on this.

[0053] It should be noted that when there are two transition pipe sections 510, there is only one throttling pipe section 520, one of which is connected to the capillary tube 300 and the throttling tube respectively, and the other is connected to the evaporating tube 200 and the throttling tube respectively; when there are three or more transition pipe sections 510, there are at least two throttling pipe sections 520, one of which is connected to the capillary tube 300 and the throttling tube respectively, and one is connected to the evaporating tube 200 and the throttling tube respectively, and the remaining transition pipe sections 510 are connected to the two throttling tubes respectively.

[0054] As can be appreciated, by alternating the transition section 510 and the throttling section 520 with different inner diameters, the refrigerant flow rate and pressure can be further controlled, thereby improving the stability and reliability of the entire evaporator and reducing the possibility of mechanical failure caused by pressure fluctuations or excessive flow rates. Furthermore, because the inner diameter of the transition section 510 is larger than the outer diameter of the capillary tube 300 and smaller than the inner diameter of the evaporator tube 200, abrupt changes in the refrigerant flow rate from the capillary tube 300 to the evaporator tube 200 are avoided, reducing noise and vibration caused by flow rate fluctuations. Furthermore, the outer diameter of the throttling section 520 is smaller than the inner diameter of the transition section 510, which reduces the refrigerant pressure and controls the flow rate entering the transition section 510. By precisely controlling the size and position of the throttling section 520 and the transition section 510, the refrigerant can be ensured to enter the evaporator tube 200 at an appropriate flow rate and volume, thereby optimizing heat exchange efficiency.

[0055] In some embodiments, the material of at least one of the transition pipe section 510 and the throttling pipe section 520 includes, but is not limited to, copper to further reduce vibration noise during refrigerant flow. Exemplarily, the copper is TU2M (oxygen-free copper).

[0056] In some embodiments, the length of the transition pipe section 510 is not less than 120 mm, which avoids high turbulence in the refrigerant flow channel, plays a role in stabilizing the flow, ensures the reduction of fluid noise and vibration, and significantly improves the noise reduction effect.

[0057] In some embodiments, as Figure 3 As shown, when the number of transition pipe sections 510 is set to at least three, the length of the transition pipe section 510 connected to one of the capillary tubes 300 or the evaporation tube 200 is greater than the lengths of the remaining transition pipe sections 510, thereby enhancing the flow stabilization effect, further weakening the fluid noise and vibration, and improving the noise reduction effect.

[0058] In some embodiments, as Figure 3 As shown, the length of the transition tube section 510 connected to one of the capillary tube 300 or the evaporation tube 200 is not less than 180 mm.

[0059] It is understandable that, considering that one end of some transition pipe sections 510 needs to be connected to the capillary tube 300 or the evaporator tube 200, by making the length of the transition pipe section 510 not less than 180 mm, the flow rate of the refrigerant can be more effectively controlled and the stability of the fluid dynamics can be maintained, the generation of turbulence and eddy currents can be reduced, and the response time of the refrigerant can be slowed down, reducing the mechanical stress and noise that may be generated by rapid response, and at the same time reducing local overheating or overcooling in the refrigerant flow, which helps to avoid unnecessary evaporation or condensation of the refrigerant and improve the reliability of the evaporator.

[0060] In this embodiment, Figure 3 As shown, three transition pipe sections 510 are provided and two throttling pipe sections 520 are provided, that is, the length of the transition pipe section 510 connected to the capillary tube 300 and the transition pipe section 510 connected to the evaporation tube 200 are not less than 180 mm, and the length of the transition pipe section 510 connected to the two throttling pipe sections 520 is not less than 120 mm.

[0061] In some embodiments, as Figure 3 As shown, the length of the throttling tube section 520 is 130 mm, which avoids the difficulty in controlling the flow rate and pressure of the refrigerant when the length is too short, and also avoids the excessive impact on the refrigerant flow in the entire evaporator when the length is too long, resulting in reduced refrigeration performance.

[0062] In some embodiments, as Figure 3 As shown, a portion of the throttling pipe section 520 is installed in the transition pipe section 510 .

[0063] It is understandable that, considering that the inner diameter of the transition pipe section 510 is larger than the outer diameter of the throttling pipe section 520, part of the throttling pipe section 520 is installed in the transition pipe section 510. This can reduce the additional pressure loss caused by the change in pipe diameter without affecting the overall flow control of the refrigerant. At the same time, this integrated design reduces additional connection points and potential leakage risks, saves space, and may reduce material and manufacturing costs, thereby improving the reliability of the evaporator.

[0064] In this embodiment, the length of the throttling pipe section 520 within the transition pipe section 510 ranges from 10 to 15 mm.

[0065] In some embodiments, as Figure 3As shown, the transition pipe section 510 includes two straight pipe bodies 511 and a curved pipe body 512. One of the two straight pipe bodies 511 is connected to the throttling pipe section 520, and the other of the two straight pipe bodies 511 is connected to the throttling pipe section 520, the capillary tube 300 or the evaporation tube 200, and the extension direction of the straight pipe body 511 is consistent with the extension direction of the throttling pipe section 520; the two ends of the curved pipe body 512 are respectively connected to the two straight pipe bodies 511, and the outer wall of the curved pipe body 512 protrudes in the direction away from the straight pipe body 511.

[0066] It is understood that, given the limited size of the base plate 100, the provision of the curved tube body 512 maximizes the transition length of the refrigerant from the capillary tube 300 to the evaporator tube 200 within the limited space, thereby enhancing the flow stabilization effect, further reducing fluid noise and vibration, improving the noise reduction effect, optimizing the spatial layout, and increasing the compactness and installation flexibility of the evaporator. Simultaneously, the straight tube body 511 provides a smooth transition area for the connection between the transition tube section 510 and the throttling tube section 520, the capillary tube 300, or the evaporator tube 200, respectively, reducing turbulence and noise caused by sudden changes in the pipe cross-section. Furthermore, the design of the curved tube body 512 helps change the flow direction of the refrigerant while reducing the impact and vibration caused by changes in flow direction. The outer wall of the curved tube body 512 protrudes away from the straight tube body 511, which also facilitates a smooth transition of the refrigerant flow and reduces energy loss.

[0067] In some embodiments, as Figure 3 As shown, the bending radius R of the curved tube body 512 is not less than 25 mm, thereby avoiding the situation where the bending radius is too small, causing the refrigerant to encounter greater resistance and disturbance during the flow process, and the refrigerant flow state changes, resulting in eddy currents and greater noise.

[0068] In some embodiments, as Figure 3 As shown, the ratio of the inner diameter of the capillary tube 300 to the inner diameter of the transition tube section 510 is in the range of 0.3 to 0.5; and / or the inner diameter of the capillary tube 300 is the same as the inner diameter of the throttling tube section 520 .

[0069] It can be understood that, on the one hand, the ratio of the inner diameters of the capillary tube 300 and the transition tube section 510 is in the range of 0.3 to 0.5, and the inner diameters of the throttling tube section 520 and the capillary tube 300 are consistent, which helps to ensure the continuity and consistency of the refrigerant flow rate, ensure that the refrigerant flows smoothly in the system, and reduce pressure loss and noise caused by sudden changes in flow rate; on the other hand, precise control of the inner diameter ratio also helps to improve the heat exchange efficiency of the evaporator, prevent the refrigerant from generating unnecessary turbulence or eddy currents, thereby reducing energy loss and system wear, and simplifying the installation and maintenance process.

[0070] In this embodiment, the ratio of the inner diameter of the capillary tube 300 to the inner diameter of the transition tube section 510 is 0.4. The inner diameter of the capillary tube 300 is the same as the inner diameter of the throttling tube section 520, that is, the ratio of the inner diameter of the throttling tube section 520 to the inner diameter of the transition tube section 510 is also 0.4.

[0071] In some embodiments, as Figure 2 and Figure 3 As shown, part of the noise reduction tube assembly 500 is installed in the evaporation tube 200 , and / or part of the capillary tube 300 is installed in the noise reduction tube assembly 500 .

[0072] It can be understood that, considering that the inner diameter of the evaporator tube 200 is larger than the outer diameter of the straight tube body 511, and the inner diameter of the straight tube body 511 is larger than the outer diameter of the capillary tube 300, part of the capillary tube 300 is installed in the straight tube body 511 and / or part of the straight tube body 511 is installed in the evaporator tube 200. This can reduce the additional pressure loss caused by the change in tube diameter without affecting the overall flow control of the refrigerant. At the same time, this integrated design reduces additional connection points and potential leakage risks, saves space, and may reduce material and manufacturing costs, thereby improving the reliability of the evaporator.

[0073] In this embodiment, part of the noise reduction tube assembly 500 is installed in the evaporator tube 200, and part of the capillary tube 300 is installed in the noise reduction tube assembly 500. Specifically, the length of the straight tube body 511 within the evaporator tube 200 ranges from 10 to 15 mm, and the length of the capillary tube 300 within the straight tube body 511 also ranges from 10 to 15 mm.

[0074] In some embodiments, the wall thickness of the noise reduction tube assembly 500 ranges from 0.95 mm to 1.05 mm.

[0075] It is understandable that the difference between the outer diameter and inner diameter of the transition pipe section 510 and the throttling pipe section 520 is within the range of 0.95mm to 1.05mm, thereby controlling the weight and material cost of the assembly while ensuring the strength and noise reduction effect of the noise reduction pipe assembly 500.

[0076] In some embodiments, as Figure 2 As shown, the evaporator further includes a return air duct 400, which is disposed on the base plate 100. The inlet end of the return air duct 400 is connected to the outlet end of the evaporation tube 200. The outlet end of the return air duct 400 is used to communicate with the outside world (e.g., the inlet end of the compressor), and at least a portion of the capillary tube 300 is installed within the return air duct 400. The connection between the return air duct 400 and the base plate 100 includes, but is not limited to, gluing, welding, or threaded connection. It should be noted that the specific size and shape of the return air duct 400 can be designed according to actual needs and is not specifically limited in this embodiment.

[0077] It should be noted that the refrigerant flows out through the outlet of the compressor and passes through the capillary tube 300, the noise reduction tube assembly 500, the evaporator tube 200 and the return air pipe 400 in sequence, and then returns to the compressor from the inlet to form a heat dissipation circuit, ensuring that the refrigerant circulates in the entire system, improving the efficiency and performance of the system. At the same time, the refrigerant flow in the capillary tube 300 is mixed with the refrigerant vapor in the return air pipe 400, which helps to pre-cool the refrigerant entering the compressor, thereby improving the working efficiency of the compressor.

[0078] It can be understood that at least part of the capillary tube 300 is installed in the return air pipe 400, which can pre-cool the refrigerant returning to the compressor, reduce the load of the compressor, extend its service life, improve the space utilization of the system, ensure the rationality of the refrigerant flow, and further reduce the vibration and noise caused by the refrigerant flow, thereby improving the user experience.

[0079] In this embodiment, the length of the capillary tube 300 in the return air pipe 400 is not less than 2000 mm.

[0080] The embodiment of the present application further provides a storage device, which includes a cabinet, a compressor, and the above-mentioned evaporator.

[0081] It should be noted that the storage equipment in the embodiment can be understood as refrigeration storage equipment in a broad sense, including but not limited to refrigerators, freezers, display cabinets, beverage cabinets, wine cabinets, cold storage cabinets and refrigerated vending machines and other refrigeration storage equipment. The storage equipment has diverse structural forms and a wide range of applications.

[0082] The cabinet body forms a storage cavity with a cabinet opening, which is used for storage. The cabinet body can be made of materials including, but not limited to, hard plastic, stainless steel, aluminum alloy, or titanium alloy. It should be noted that the shapes and sizes of the cabinet body, cabinet opening, and storage cavity can be designed according to actual needs and are not specifically limited in this embodiment.

[0083] The compressor is installed in the cabinet. The connection methods between the compressor and the cabinet include but are not limited to threaded connection, rivet connection, snap connection or welding.

[0084] It is understandable that the structure of the cabinet can provide a certain degree of sound insulation and vibration reduction for the compressor, help reduce the operating noise and vibration of the storage equipment, improve the user experience, and also play a role in dust protection, helping to maintain the stability and reliability of the storage system.

[0085] The evaporator is installed in the cabinet and connected to the compressor to form a heat dissipation circuit. The connection between the evaporator and the cabinet includes but is not limited to threaded connection, rivet connection, snap connection or welding.

[0086] It's understandable that connecting the evaporator to the compressor to form a heat dissipation circuit effectively manages the heat generated by the compressor, maintaining it at an appropriate operating temperature and improving its efficiency and lifespan. The cabinet structure also provides sound insulation and vibration reduction for the evaporator, helping to reduce operating noise and vibration in the storage device, improving the user experience. It also provides dust protection, helping to maintain the stability and reliability of the storage system.

[0087] According to the storage device provided in the embodiment of the present application, a noise reduction tube assembly 500 is arranged between the capillary tube 300 and the evaporation tube 200 in the evaporator, and the inner diameter of the noise reduction tube is larger than the outer diameter of the capillary tube 300 and smaller than the inner diameter of the evaporation tube 200, thereby making the process of the refrigerant flowing from the capillary tube 300 to the evaporation tube 200 smoother, reducing the airflow noise caused by rapid changes in pressure and flow rate, and making the overall operation of the evaporator more stable, which not only improves the service life of the system, but also reduces maintenance costs and operating costs, and improves the user experience.

[0088] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited.
