Description

Technical Field

[0001] This utility model relates to the field of cold storage technology, specifically to an air guide component, a cold storage unit equipped with the air guide component, and a cold storage system equipped with the aforementioned cold storage unit. Background Technology

[0002] Cold storage systems are primarily used for preserving items with specific temperature and humidity requirements. Compared to traditional refrigerators, cold storage systems offer greater cooling capacity and storage space, and are widely used in food, chemical, medical, and scientific research fields. Traditional cold storage systems cool the storage room by laying out refrigeration pipes within the room, allowing heat exchange between the pipes and the air inside. However, defrosting these pipes requires the entire refrigeration system to stop operating, allowing the frost to melt naturally. This results in long defrosting times, low defrosting efficiency, and poor overall cooling efficiency.

[0003] In response, a new type of refrigeration unit has been introduced to replace the refrigeration pipes in cold storage facilities, such as... Figure 1 As shown, the cold storage unit 9 includes a casing 91, a heat exchanger 92, a fan module 93, and a mesh cover 94. The casing 91 has an air outlet. The heat exchanger 92 and the fan module 93 are both located inside the casing 91. The fan module 93 is positioned between the heat exchanger 92 and the air outlet, and is used to blow air into the cold storage room, delivering the cold air generated by heat exchange in the heat exchanger 92 into the room. The mesh cover 94 is installed on the casing 91, located outside the casing 91, and covers the air outlet. Although the cold storage system equipped with this cold storage unit 9 can solve the shortcomings of traditional cold storage systems using refrigerated pipes, the aforementioned cold storage unit 9 still has the following deficiencies:

[0004] Since the mesh cover 94 is a steel wire mesh cover 94, when the fan module 93 blows the cold air formed by heat exchange of heat exchanger 92 out through the air outlet and mesh cover 94, it can only achieve horizontal air outlet (that is, the cold air is blown out along the axial direction of the air outlet). In actual use, factors such as the installation location of the cold storage unit 9 and the storage requirements of the goods necessitate different requirements for the airflow direction of the cold storage unit 9. For example, in some scenarios, it is required that the cold air not blow directly onto the goods to avoid dehumidification loss, in which case the cold storage unit 9 needs to blow air upwards; in other scenarios, rapid cooling is required, in which case the cold storage unit 9 needs to blow air downwards; in still other scenarios, due to installation limitations, the installation location of the cold storage unit 9 is located off the side of the warehouse, in which case the cold storage unit 9 needs to blow air to the right or left; in yet another scenario, due to the large warehouse space, the cold storage unit 9 needs to blow air at a wide angle to the left and right, or due to the small warehouse space, the cold storage unit 9 needs to blow air in the center, and so on. However, the existing cold storage unit 9 cannot meet the above requirements, resulting in limited flexibility and practicality in its use. Summary of the Invention

[0005] To address the aforementioned problems, the main objective of this invention is to provide an air guide assembly that allows for adjustment of the air outlet direction of the unit inside a cold storage facility.

[0006] Another objective of this invention is to provide a cold storage unit equipped with the aforementioned air guiding components.

[0007] Another objective of this utility model is to provide a cold storage system equipped with the aforementioned cold storage internal unit.

[0008] To achieve the main objective of this utility model, it provides an air guiding assembly, comprising a panel and a guide shroud. The panel has an air outlet and a first connecting structure. The air outlet penetrates the panel along its own axial direction. The guide shroud covers the air outlet. The guide shroud has a frame and multiple guide vanes. The frame has a second connecting structure that cooperates with the first connecting structure. The multiple guide vanes are distributed along a first direction. Both ends of the guide vanes are connected to the frame. A non-zero angle is formed between the guide vanes and the axial section of the air outlet. The non-zero angle is less than 90°. An air outlet channel is formed between the frame and the multiple guide vanes. The guide shroud can switch the air outlet direction of the air outlet channel through the first connecting structure and the second connecting structure.

[0009] As can be seen from the above, the design of the air guide shroud ensures that the air blown out through the shroud is not horizontal. At the same time, the relative assembly position between the air guide shroud and the panel is adjustable through the cooperation between the second connecting structure on the air guide shroud and the first connecting structure on the panel. This allows the air outlet direction of the air guide shroud to be adjusted according to the installation position of the cold storage unit equipped with this air guide component in the warehouse and / or the refrigeration requirements, thereby expanding the applicability of the cold storage unit and improving its flexibility and practicality.

[0010] A preferred embodiment is that the first connecting structure includes multiple first connecting parts, which are evenly distributed around the air outlet; the second connecting structure includes multiple second connecting parts, which are detachably connected to a first connecting part.

[0011] As can be seen from the above, this design allows the air deflector to change its relative position to the panel by switching each second connection from the currently engaged first connection to another first connection, thereby changing the air outlet direction of the air deflector.

[0012] A further option is that the first connecting part is a first connecting hole, the second connecting part is a second connecting hole, and the first connecting hole and the second connecting hole are connected by bolts; or the first connecting part is a slot, the second connecting part is a buckle, and the slot and buckle are engaged; or the first connecting part is a first magnet, the second connecting part is a second magnet, and the first magnet and the second magnet generate a magnetic force that attracts each other.

[0013] As can be seen from the above, all of the above designs make it easier and more convenient to switch the relative positions of the fairing and the panel.

[0014] A further option is to have four first connecting parts, so that when the air guide assembly is in the installation position, the air outlet direction of the air outlet duct can be switched to top air outlet, left air outlet, bottom air outlet, or right air outlet by the cooperation of the first connecting structure and the second connecting structure; or to have eight first connecting parts, so that when the air guide assembly is in the installation position, the air outlet direction of the air outlet duct can be switched to top air outlet, upper left air outlet, left air outlet, lower left air outlet, bottom air outlet, lower right air outlet, right air outlet, or upper right air outlet by the cooperation of the first connecting structure and the second connecting structure.

[0015] As can be seen from the above, the number of different air outlet directions of the air guide can be determined by designing the number of the first connecting parts. At the same time, this design is conducive to better optimizing the structure of the air guide assembly, especially the optimization of the air guide structure, making the air guide molding simpler, lower in cost and higher in structural strength. In addition, it is also conducive to improving the overall aesthetics of the air guide assembly.

[0016] Another preferred embodiment is that the frame includes a first frame and a second frame, a guide vane is disposed on the first frame, the second frame is detachably connected to the first frame, an annular groove is formed between the second frame and the first frame, the outer contour of the frame and the air outlet are both circular, the opening of the air outlet is engaged in the annular groove, and the guide shroud can rotate around the axis of the air outlet; the air guide assembly includes a shock-absorbing ring, which is installed in the annular groove and is adjacent to the panel and the frame.

[0017] As can be seen from the above, the structural design of the frame allows for stepless adjustment of the relative position between the air guide and the panel, which in turn allows for stepless adjustment of the air outlet direction of the air guide. This makes the installation position of the cold storage unit equipped with this air guide component in the warehouse more flexible and / or meets more refrigeration requirements, thereby expanding the application range of the cold storage unit and improving its flexibility and practicality.

[0018] A further embodiment is that at least a portion of the guide vane has protrusions extending from the inner end face of the guide vane to the outer end face of the guide vane, with the outer peripheral surface of the protrusions smoothly transitioning; and / or the frame also has multiple reinforcing ribs distributed along a second direction, the reinforcing ribs extending along a first direction, both ends of the reinforcing ribs being connected to the frame, the guide vane extending along the second direction, and the first direction, the second direction, and the axial direction being mutually perpendicular.

[0019] As can be seen from the above, setting protrusions on the air guide plate can improve the uniformity of cold air distribution in the warehouse, reduce noise and improve air guiding efficiency; while setting reinforcing ribs can enhance the strength of the frame and air guide plate.

[0020] A further improvement is that the air deflector is made of polyethylene, polypropylene, polytetrafluoroethylene, polyamide or polyetheretherketone material by injection molding; and / or the frame is provided with air outlet markings; and / or the inner side of the panel is provided with an air guide ring around the air outlet, and the inlet end of the air guide ring is formed with a guide surface.

[0021] As can be seen from the above, by selecting the materials for the air guide, the air guide can withstand low and ultra-low temperatures, thereby extending the service life of the air guide; the air guide ring is used to guide the cold air drawn by the fan unit, so that the cold air can be better and more completely discharged from the air outlet of the unit in the cold storage, thereby improving the refrigeration efficiency of the unit in the cold storage.

[0022] To achieve another objective of this utility model, this utility model provides a cold storage unit, including a casing, a heat exchanger, and a fan module. The heat exchanger and the fan module are both installed inside the casing. The cold storage unit also includes the aforementioned air guide assembly. The panel is connected to the casing, and the fan module is located between the air outlet and the heat exchanger.

[0023] As can be seen from the above, the air guide components installed in the cold storage unit allow the air outlet direction of the air guide shroud to be adjusted according to the installation location of the cold storage unit in the warehouse and / or the refrigeration requirements, thereby expanding the applicable range of the cold storage unit and making it more flexible and practical.

[0024] A further option is to have two or more air guide components, two or more fan modules, with each fan module corresponding to one or more air guide components; and / or the panel and the chassis are detachably connected, or the panel and the chassis are integrally formed.

[0025] As can be seen from the above, setting the number of air guide components and fan modules to two or more can increase the cooling capacity of the cold storage unit, while also enabling the cold storage unit to have multi-directional composite air supply capability, so as to be suitable for more types of use environments, meet more use needs, and be more practical; the detachable connection between the panel and the chassis makes the production of the cold storage unit more flexible, and the splicing and assembly design of the chassis can save material storage space and help reduce production costs; while making the panel and chassis integrally molded can reduce assembly steps and the number of parts required for assembly.

[0026] To achieve another objective of this utility model, this utility model provides a cold storage system, including a warehouse and an external cold storage unit, wherein the external cold storage unit is located outside the warehouse. The cold storage system also includes the aforementioned internal cold storage unit, which is located inside the warehouse and connected to the external cold storage unit.

[0027] As can be seen from the above, by installing the aforementioned cold storage units, the cold storage system can meet more refrigeration and cargo storage needs, thereby improving the practicality of the cold storage units. Attached Figure Description

[0037] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0038] First embodiment of cold storage unit

[0039] Reference Figure 2 and Figure 3 The cold storage unit 100 includes an air guide assembly 101, a casing 102, a heat exchanger 103, and a fan module 104. The number of air guide assemblies 101 and fan modules 104 can be one; however, in some embodiments, the number of air guide assemblies 101 and fan modules 104 can be two or more, with one or more air guide assemblies 101 corresponding to one or more fan modules 104. For example, in this embodiment, the number of air guide assemblies 101 and fan modules 104 are both two. When the number of air guide components 101 and fan modules 104 is set to two or more, the cooling capacity of the cold storage unit 100 can be increased. At the same time, with the design of the air guide components 101 (see the description below), the cold storage unit 100 can achieve unidirectional air supply or multi-directional composite air supply (such as at least some of the air guide 2 in two or more air guide hoods 2 having different air outlet directions). This makes the cold storage unit 100 suitable for more types of environments, meets more usage needs, and enhances the practicality of the cold storage unit 100.

[0040] Combination Figures 4 to 6 The air guide assembly 101 includes a panel 1 and a guide shroud 2. The panel 1 is provided with an air outlet 11 and a first connecting structure, and the air outlet 11 penetrates the panel 1 in its own axial direction (that is, in the thickness direction of the panel 1).

[0041] Panel 1 is connected to chassis 102. In this embodiment, panel 1 is detachably connected to chassis 102, and chassis 102 is preferably a split design, that is, chassis 102 can be assembled by two side panels 1021, a top panel 1022 and a bottom panel 1023. The top panel 1022 is connected between the top of the two side panels 1021, and the bottom panel 1023 is connected between the bottom of the two side panels 1021, so that the two side panels 1021, the top panel 1022 and the bottom panel 1023 form a return air vent at the back of chassis 102, while the two side panels 1021, the top panel 1022 and the bottom panel 1023 form an opening at the front of chassis 102. Panel 1 is installed on the opening and is connected to the top panel 1022 and / or the bottom panel 1023 by bolts. Furthermore, depending on the number of air guide components 101 and fan modules 104 configured in the cold storage unit 100, the panel 1 is connected to the two side plates 1021 by bolts. For example, in this embodiment, since there are two air guide components 101, the panel 1 of the first air guide component 101 is also connected to the first side plate 1021 by bolts, and the panel 1 of the second air guide component 101 is also connected to the second side plate 1021 by bolts. For another example, in some embodiments, there is only one air guide component 101, in which case the panel 1 of the air guide component 101 is connected to the two side plates 1021 by bolts respectively. For yet another example, in some embodiments, there are three or more air guide components 101, in which case the panel 1 of the air guide component 101 closest to the side plate 1021 is connected to the side plate 102 by bolts. The panel 1 is designed to be detachably connected to the chassis 102, which makes the production flexibility of the unit 100 in the cold storage better. In addition, the design of the split chassis 102 helps to save storage space for the production materials of the unit 100 in the cold storage (such as the panel 1, the side panels 1021, the top panel 1022 and the bottom panel 1023 of the split chassis 102, etc.) and helps to reduce production costs.

[0042] Of course, as another alternative, in other embodiments, the chassis 102 can be a one-piece structure, and the panel 1 and the chassis 102 are integrally formed. This design can reduce the assembly process and the number of parts required for assembly.

[0043] Furthermore, in some embodiments, an air guide ring 13 is provided on the inner side of the panel 1, and the air guide ring 13 surrounds the air outlet 11 of the panel 1 in the circumferential direction; wherein, the air guide ring 13 can be integrally formed with the panel 1, or can be detachably or non-detachably connected to the panel 1. The air guide ring 13 is used to guide the cold air drawn by the fan module 104 to the air outlet 11, so that the cold air is better and more completely discharged from the casing 102 to the air outlet 11, thereby improving the cooling efficiency of the unit 100 in the cold storage. Furthermore, the inlet end of the air guide ring 13 is preferably formed with a guide surface 131, which can better guide the cold air into the air guide ring 13.

[0044] Combination Figure 7 The air deflector 2 has a frame 21 and multiple air deflector plates 22. The multiple air deflector plates 22 are distributed along a first direction and extend along a second direction, with both ends of the air deflector plates 22 connected to the frame 21. The first direction, the second direction, and the axial direction of the air outlet 11 are mutually perpendicular, and the air deflector plates 22 are integrally formed with the frame 21. An air outlet channel is formed between the frame 21 and the multiple air deflector plates 22. A non-zero included angle α is formed between the air deflector plates 22 and the axial section of the air outlet 11. This non-zero included angle α is less than 90°, making the direction of the air outlet channel non-horizontal (i.e., not parallel to the axial direction of the air outlet 11).

[0045] The frame 21 is provided with a second connecting part 211, which is used to cooperate with the first connecting part 121 to install the air guide 2 onto the panel 1 and cover the air outlet 11. In addition, the air guide 2 can switch the air outlet direction of the air outlet channel through the first connecting structure and the second connecting structure.

[0046] In some embodiments, the first connecting structure includes a plurality of first connecting portions 121, which are evenly distributed around the air outlet 11. Correspondingly, the second connecting structure includes a plurality of second connecting portions 211, and each second connecting portion 211 can be detachably connected to one of the first connecting portions 121. Therefore, when it is necessary to change the air outlet direction of the guide shroud 2, each second connecting portion 211 on the guide shroud 2 is switched from being connected to the currently engaged first connecting portion 121 to being connected to another first connecting portion 121, thereby changing the relative position of the guide vane 22 on the guide shroud 2 and the panel 1, and thus changing the air outlet direction of the air outlet channel. For example, in this embodiment, the first connecting part 121 is a first connecting hole, and the second connecting part 211 is a second connecting hole. When the panel 1 is assembled with the air guide 2, the bolt connects the first connecting hole and the second connecting hole. As another optional solution, in other embodiments, the first connecting part 121 can be a slot, and the second connecting part 211 can be a buckle. When the panel 1 is assembled with the air guide 2, the slot and the buckle engage. As yet another optional solution, in other embodiments, the first connecting part 121 can be a first magnet, and the second connecting part 211 can be a second magnet. The first magnet and the second magnet generate an attractive magnetic force. When the panel 1 is assembled with the air guide 2, the first magnet and the second magnet are attracted and fixed together. The above design of the first connecting part 121 and the second connecting part 211 makes the switching of the relative position between the air guide 2 and the panel 1 more convenient and easier to operate.

[0047] In some embodiments, the number of first connecting parts 121 may be four, and more preferably, the number of second connecting parts 211 may also be four to improve the reliability of the connection between the air guide 2 and the panel 1. Of course, as an optional solution, the number of second connecting parts 211 may be less than the number of first connecting parts 121, provided that each second connecting part 211 can be connected to a first connecting part 121. When the number of first connecting parts 121 is four and the air guide assembly 101 is in the mounting position (i.e., the air guide assembly 101 is installed on the chassis 102), the air outlet direction of the air guide 2 can be switched to top air outlet, left air outlet, bottom air outlet, or right air outlet through the cooperation of the first connecting structure and the second connecting structure.

[0048] In some embodiments, the number of first connecting parts 121 can be set to eight. In this case, the number of second connecting parts 211 is preferably four, and each second connecting part 211 can be connected to one first connecting part 121. When the number of first connecting parts 121 is eight and the air guide assembly 101 is in the mounting position (i.e., the air guide assembly 101 is installed on the chassis 102), the air outlet direction of the air outlet channel of the air guide shroud 2 can be switched to upper air outlet, upper left air outlet, left air outlet, lower left air outlet, lower right air outlet, right air outlet, or upper right air outlet by the cooperation of the first connecting structure and the second connecting structure. It can be seen that the number of different air outlet directions of the air guide shroud 2 can be determined by designing the number of first connecting parts 121. At the same time, this design is conducive to better optimizing the structure of the air guide assembly 101, especially the optimization of the structure of the air guide shroud 2, making the molding of the air guide shroud 2 simpler, the cost lower, and the structural strength higher. In addition, it is also conducive to improving the overall aesthetics of the air guide assembly 101.

[0049] By connecting the second connecting structure with the first connecting structure, the relative assembly position between the air guide shroud 2 and the panel 1 is adjustable. This allows the air outlet direction of the air guide shroud 2 to be adjusted according to the installation position of the cold storage unit 100 in the warehouse and / or the refrigeration requirements, thereby expanding the applicability of the cold storage unit 100 and improving its flexibility and practicality. Compared to existing cold storage units 100, the cold storage unit 100 provided by this utility model can change the air supply direction of the cold storage unit 100 simply by connecting the first connecting structure of the panel 1 with the second connecting structure of the air guide shroud 2. There is no need to additionally set up air ducts to connect with the mesh cover and the air outlet 11 to change the air supply direction. Therefore, there is no problem of reduced air volume and poor refrigeration effect due to the installation of air ducts, nor is there a problem of air ducts occupying warehouse space.

[0050] In some embodiments, at least a portion of the air guide vanes 22 of the air guide shroud 2 is provided with protrusions 221, wherein the protrusions 221 extend from the inner end face of the air guide vane 22 (i.e., the side of the air guide vane 22 facing the fan module 104) to the outer end face of the air guide vane 22 (i.e., the side of the air guide vane 22 facing away from the fan module 104), and the outer peripheral surface 2211 of the protrusions 221 is smoothly transitioned; preferably, the protrusions 221 are located on the windward side of the air guide vane 22. The arrangement of the protrusions 221 is beneficial to enhance the turbulence and mixing of airflow, so as to improve the uniformity of cold air distribution in the warehouse, and can also reduce noise and improve the air guiding efficiency.

[0051] In some embodiments, the frame 21 also has a plurality of reinforcing ribs 23, which are distributed along a second direction and extend along a first direction. Both ends of the reinforcing ribs 23 are connected to the frame 21. The reinforcement ribs 23 can increase the strength of the frame 21 and the guide plate 22.

[0052] In some embodiments, the flow deflector 2 is made of low-temperature resistant materials through injection molding, such as polyethylene (PE), polypropylene (PP), polytetrafluoroethylene (PRFE), polyamide (PA), or polyether ether ketone (PEEK), making the flow deflector 2 lightweight and better suited for low-temperature and ultra-low-temperature environments in warehouses, while also ensuring the service life and operational reliability of the flow deflector 2.

[0053] In some embodiments, the air deflector 2 is further provided with an air outlet mark 24, the direction of which is consistent with the air outlet direction of the air outlet channel, so that the user can quickly know the current air outlet direction of the air deflector 2, thereby facilitating the user to assemble the air deflector 2 with the panel 1 and facilitating the user to change the air outlet direction of the air deflector 2.

[0054] Both the heat exchanger 103 and the fan module 104 are installed inside the casing 102. The heat exchanger 103 is located at the return air inlet of the casing 102, and the fan module 104 is located between the air outlet 11 of the guide shroud 2 and the heat exchanger 103.

[0055] In summary, by designing the air guide component 101 of the cold storage unit 100, the air outlet direction of the air guide hood 2 can be adjusted according to the installation position of the cold storage unit 100 in the warehouse and / or the refrigeration requirements, thereby expanding the applicability of the cold storage unit 100 and making the cold storage unit 100 more flexible and practical.

[0056] Second embodiment of cold storage unit

[0057] Reference Figure 8 and Figure 9 The difference between this embodiment and the first embodiment of the cold storage unit lies in the connection structure between the panel and the deflector (i.e., the first connection structure and the second connection structure). Specifically, in this embodiment:

[0058] The frame 31 of the air deflector 3 includes a first frame 311 and a second frame 312; wherein the air deflector 32 and the air outlet mark 33 are both provided on the first frame 311.

[0059] The first frame 311 and the second frame 312 are detachably connected; in some embodiments, the detachability can be achieved by connecting the first frame 311 and the second frame 312 with bolts; in some embodiments, the detachable connection is achieved by connecting the first frame 311 and the second frame 312 with a snap-fit ​​structure; in some embodiments, the detachable connection is achieved by connecting the first frame 311 and the second frame 312 with a magnetic assembly.

[0060] When the panel 4 is assembled with the air guide 3, the second frame 312 and the first frame 311 are distributed along the axial direction of the air outlet 41 of the panel 4, with the second frame 312 located on the inner side of the panel 4 and the first frame 311 located on the outer side of the panel 4. After the first frame 311 and the second frame 312 are assembled, an annular groove 310 (i.e., the second connecting structure) is formed between the second frame 312 and the first frame 311, and the opening of the air outlet 41 (referring to the panel part around the air outlet 41, i.e., the first connecting structure) is engaged in the annular groove 310. The outer contour of the frame 31 and the air outlet 41 are both circular, so that the air guide 3 can rotate around the axis of the air outlet 41.

[0061] This design allows for stepless adjustment of the relative position between the air deflector 3 and the panel 4, which means that the air outlet direction of the air deflector 3 can be adjusted steplessly. When it is necessary to adjust the air outlet direction of the air deflector 3, the air outlet direction of the air deflector 3 can be changed by controlling the air deflector 3 to rotate relative to the panel 4 around the axis of the air outlet 41, making the adjustment of the air outlet direction more convenient and easier to operate.

[0062] In some embodiments, the air guide assembly includes a shock-absorbing ring installed within an annular groove 310, adjacent to the panel 4 and the frame 31. The shock-absorbing ring fills the gap between the annular groove 310 and the panel 4, thus providing shock absorption, buffering, and noise reduction. Furthermore, the shock-absorbing ring can, to a certain extent, prevent the air guide shroud 3 from rotating relative to the panel 4. It should be noted that the shock-absorbing ring's ability to prevent the air guide shroud 3 from rotating relative to the panel 4 means that when the air guide assembly is subjected to vibration, the shock-absorbing ring can prevent the air guide shroud 3 from rotating relative to the panel 4, ensuring that the airflow direction remains unchanged. However, when the user operates the air guide shroud 3 to rotate relative to the panel 4, the air guide shroud 3 can rotate relative to the panel 4. Preferably, the shock-absorbing ring is made of sponge.

[0063] Cold storage system examples

[0064] The cold storage system includes a warehouse, an outdoor cold storage unit, and an indoor cold storage unit; wherein, the indoor cold storage unit is the same as the one described in the first or second embodiment above. The outdoor cold storage unit is located outside the warehouse, and the indoor cold storage unit is located inside the warehouse and connected to the outdoor cold storage unit. Through the aforementioned indoor cold storage unit, the cold storage system can meet more refrigeration and goods storage needs, making it more practical and applicable to a wider range of situations.

[0065] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
