Description

Technical Field

[0001] This utility model relates to the field of cold storage equipment technology, specifically to a flexible cold storage module for cold storage and a cold storage including the cold storage module. Background Technology

[0002] Traditional cold storage operations rely primarily on the continuous operation of refrigeration compressor units, which use air coolers to circulate cooling energy into the storage area, maintaining a constant low temperature environment. However, this operating model has significant drawbacks. During peak electricity consumption periods in summer, or when facing unstable power supply during long-distance transportation, the refrigeration efficiency of the units drops sharply, leading to uncontrolled temperature fluctuations within the storage area, directly impacting the safety and quality of the stored goods.

[0003] To address energy consumption challenges, cold storage technology has gradually gained industry attention. Its core principle is to store the cooling energy during off-peak hours for use during peak hours. However, traditional cold storage technologies mostly use water-based methods. This method not only requires a large equipment footprint and has limited storage capacity, but also has a small temperature difference, which greatly limits its application scenarios and makes it difficult to fully realize its value in industrial production. Large-scale promotion faces numerous obstacles.

[0004] Phase change energy storage devices can fully utilize electricity during off-peak hours, effectively reducing the operating costs of cold storage facilities. They can shift peak electricity demand to off-peak hours, achieving peak shaving and valley filling of the power load, optimizing power resource allocation, and alleviating peak power supply pressure. In practical applications, phase change energy storage devices significantly improve energy storage efficiency and reduce overall operating costs. For example, the energy storage device described in Reference 1:

[0005] Reference 1: Chinese patent document with publication number CN216432194U

[0006] Reference 1 describes a cold storage device and cold storage facility, comprising K×N cold storage units and N air-cooling units, where K and N are both positive integers. Each cold storage unit includes a support frame and multiple cold storage plates. Each cold storage plate includes a shell and cold storage material filled within the shell. Assembly holes are provided through the shell. The support frame passes sequentially through the assembly holes of the multiple cold storage plates to fix them, forming a cold storage unit. Air-cooling units are used to blow air onto the cold storage plates to increase the rate at which the cold storage plates store or release cold energy. The cold storage facility includes the aforementioned cold storage device and also includes A rows of shelves. There are A cold storage devices, each installed on one of the A rows of shelves. Items are placed between adjacent rows of shelves, where A is a positive integer greater than or equal to 2. This cold storage device can reduce temperature fluctuations within the cold storage facility, providing a stable storage environment for the items inside.

[0007] While the cold storage device in Reference 1 can reduce temperature fluctuations and provide a stable storage environment, it suffers from low space utilization. Its cold storage plates are only installed on shelves, failing to fully utilize other spaces within the cold storage. Furthermore, the cold storage plates require mold forming, resulting in high costs. Therefore, it is recommended to consider installing lower-cost, flexible phase change cold storage bags within the cold storage. Utility Model Content

[0008] The purpose of this utility model is to solve the above-mentioned technical problems by providing a flexible cold storage module for cold storage and a cold storage including the cold storage module.

[0009] To address the shortcomings of the aforementioned technical problems, the present invention adopts the following technical solution: a flexible cold storage module for cold storage, comprising a cold storage bag and an installation assembly for fixing the cold storage bag to the top plate of the cold storage.

[0010] The installation assembly includes fasteners that can be fixed to the top panel of the cold storage and hooks for connecting the fasteners and the cold storage bags;

[0011] The cold storage bag includes a bag body with a receiving cavity inside, which is filled with a phase change cold storage material. The edge of the bag body is provided with fixing holes that cooperate with hooks in the installation assembly.

[0012] As a further optimization of the flexible cold storage module for cold storage of this utility model: the phase change cold storage material is an organic compound, a hydrated salt, or an aqueous solution of salt.

[0013] As a further optimization of the flexible cold storage module for cold storage of this utility model: the bag body has several independent accommodating cavities.

[0014] As a further optimization of the flexible cold storage module for cold storage of this utility model: the fixing component is an expansion bolt.

[0015] As a further optimization of the flexible cold storage module for cold storage of this utility model: the fixing component is a ceiling track, and the hook can slide on the ceiling track.

[0016] As a further optimization of the flexible cold storage module for cold storage of this utility model: the fixing component is a strong magnet base.

[0017] As a further optimization of the flexible cold storage module for cold storage of this utility model: the fixing component is a vacuum suction cup or a plastic rivet.

[0018] As a further optimization of the flexible cold storage module for cold storage of this utility model: the fixing component is a hanging ring pre-embedded in the top plate.

[0019] This utility model also provides a cold storage, including a shelf, which is composed of uprights and multiple layers of crossbeams. Several cold storage units are arranged between two opposite crossbeams on the same layer. Each cold storage unit includes two longitudinal rods and several cold storage boxes. Several cold storage boxes are inserted along the length of the two longitudinal rods. The two ends of the longitudinal rods are connected to the crossbeams by hooks. Several of the above-mentioned flexible cold storage modules are provided on the top plate of the cold storage.

[0020] As a further optimization of the cold storage of this utility model: the hanging component is an L-shaped plate, the horizontal part of which can be erected on the crossbeam, and the vertical part is provided with through holes through which the longitudinal rods can pass.

[0021] This invention offers the following advantages: By utilizing a fixing assembly to install multiple flexible phase-change cold storage bags on the top panel of the cold storage facility, the space utilization rate of the cold storage is effectively improved. The flexible phase-change cold storage bags can store cold energy and release it at appropriate times, ensuring stable internal temperature and significantly enhancing the cold storage's insulation effect.

[0035] To better understand this utility model, the following embodiments further illustrate the content of this utility model, but the content of this utility model is not limited to the following embodiments.

[0036] <Example 1>

[0037] like Figure 1-2 As shown, a flexible cold storage module for cold storage includes a cold storage bag 1 and an installation assembly for fixing the cold storage bag 1 to the top plate 2 of the cold storage.

[0038] The mounting components include fasteners 3 that can be fixed to the top plate 2 of the cold storage room and hooks 4 for connecting the fasteners 3 and the cold storage bag 1. The cold storage bag 1 includes a bag body made of a high-strength, low-temperature resistant and flexible polymer composite material, which can be used stably in a temperature range of -30℃ to 50℃, effectively resisting the corrosion of the harsh environment inside the cold storage room.

[0039] The bag contains cavities filled with phase change cold storage material. In this embodiment, the bag has several independent cavities. Damage to one cavity will not affect the normal operation of other cavities, reducing the risk of overall cold storage bag failure and greatly improving the reliability and service life of the cold storage bag.

[0040] Phase change energy storage materials are organic compounds, hydrated salts, or aqueous solutions of salts. Organic compound phase change energy storage materials have advantages such as high latent heat of phase change, stable chemical properties, and non-corrosiveness, making them suitable for cold storage scenarios with high temperature control precision requirements. Hydrated salt phase change energy storage materials have lower costs, a wide phase change temperature range, and can be customized to meet the temperature requirements of different cold storage facilities. Aqueous solution phase change energy storage materials have good fluidity and fast charging and releasing speeds, enabling rapid response to temperature changes within the cold storage. Along the edge of the bag, there are evenly distributed fixing holes 5 that mate with hooks 4 in the installation assembly. The fixing holes 5 are specially reinforced, using metal collars embedded in the edge of the bag, which enhances the load-bearing capacity of the fixing holes and prevents wear on the bag during long-term use, ensuring a stable connection between the energy storage bag and the installation assembly.

[0041] The fastener 3 is an expansion bolt with an anti-corrosion coating, which can be firmly fixed to the cold storage top plate 2. One end of the hook 4 can be screwed onto the expansion bolt for quick installation and removal; the other end is a pointed hook that can accurately pass through the fixing hole 5 of the cold storage bag 1, and a non-slip rubber sleeve is provided at the hook to ensure that the cold storage bag will not shake or fall off when suspended, thus ensuring the safety and stability of the entire cold storage module during cold storage operation.

[0042] <Example 2>

[0043] The overall structure of this embodiment is the same as that of <Embodiment 1>, except that: the fixing component 3 is a ceiling track, and the hook 4 can slide on the ceiling track. The ceiling track is made of high-strength aluminum alloy and is integrally formed with a "T" shaped cross-section, wider at the top and narrower at the bottom. The upper wide surface is used to firmly connect to the cold storage top plate 2 with expansion bolts. To ensure a firm installation, an installation hole is set every 50cm, and the installation spacing can be adjusted according to the actual load-bearing capacity of the cold storage top plate and the layout of the cold storage modules. The lower narrow surface is the slide rail. The width of the inner groove of the slide rail is adapted to the size of the hook 4. Guide and limiting protrusions are provided on both sides of the inner groove to prevent the hook from shifting laterally or coming off during sliding, ensuring a smooth and stable sliding process. The track length can be customized according to the actual space of the cold storage. The tracks are spliced ​​together with special connectors. The connectors adopt a mortise and tenon structure and are reinforced with built-in high-strength bolts. After splicing, the track surface is flat and smooth with no obvious seams, which does not affect the sliding of the hook. To prevent the hook from accidentally sliding when it is not needed, a locking device is provided in the sliding part. The locking device uses a push-button spring-loaded latch structure. When the hook needs to be fixed in position, press the latch, and it will engage with a pre-set slot on the side of the track to lock the hook. Pressing the latch again will release the lock and restore the hook's sliding function. In addition, limit stops are installed at both ends of the track to prevent the hook from slipping off the track and ensure the safety of the cold storage module installation.

[0044] <Example 3>

[0045] The overall structure of this embodiment is the same as that of <Embodiment 1>, except that the fixing component 3 is a strong magnet base. The strong magnet base uses high-performance neodymium iron boron permanent magnet material, which can maintain stable magnetism in low-temperature environments. The base is flat and cylindrical, directly contacting the top plate 2 of the cold storage, and achieving firm adsorption through strong magnetic force. The top is provided with a dovetail groove structure for installing the hook 4. The dimensions of the dovetail groove are precisely designed to ensure the stability of the hook after installation, while also facilitating quick disassembly and sliding adjustment.

[0046] To enhance the durability and safety of the base, two protective layers are wrapped around the neodymium iron boron permanent magnet. The inner layer is a high-strength epoxy resin encapsulation layer, which isolates the permanent magnet from the external environment and prevents it from oxidizing and corroding; the outer layer is a stainless steel protective shell with a frosted surface to increase friction and prevent the base from accidentally sliding on the top plate of the cold storage.

[0047] The hook 4 adopts an "L"-shaped design, with its vertical end embedded in the dovetail groove at the top of the strong magnet base, and its horizontal end used to suspend the cold storage bag 1. Wedge-shaped sliders matching the dovetail groove are set on both sides of the vertical end. The surface of the sliders is covered with an anti-slip silicone layer. When the hook is inserted into the dovetail groove, the wedge-shaped sliders expand outward under the squeezing action of the dovetail groove, tightly engaging with the dovetail groove to form a strong mechanical connection.

[0048] <Example 4>

[0049] The overall structure of this embodiment is the same as that of <Embodiment 1>, except that the fixing component 3 is a vacuum suction cup. The main body of the vacuum suction cup is made of low-temperature resistant and highly elastic nitrile rubber. This material can maintain good flexibility and sealing performance in a temperature range of -40℃ to 80℃, adapting to the low-temperature environment inside the cold storage. The suction cup is in the shape of a flat frustum. A reinforcing skeleton is set inside the suction cup. The skeleton is made of high-strength carbon fiber and is radially distributed inside the suction cup to enhance the suction cup's resistance to deformation under negative pressure and prevent the suction cup from breaking or deforming due to excessive suction force.

[0050] <Example 5>

[0051] The overall structure of this embodiment is the same as that of <Embodiment 1>, except that: the fixing component 3 is a plastic rivet, which is directly fixed in the fixing hole. The plastic rivet is a PA66+30% glass fiber reinforced expansion rivet. The rivet body has a self-locking anti-reverse ratchet structure, and the matching hook is a PP+30% carbon fiber composite injection molded part with a static load ≥30kg.

[0052] <Example 6>

[0053] like Figure 3 The illustration depicts a cold storage facility, including shelving. The shelving serves as the core supporting structure within the cold storage, forming a stable three-dimensional frame system comprised of uprights 6 and multiple layers of beams 7. The uprights 6, as the primary load-bearing components, are perpendicular to the cold storage floor and reliably connected to the foundation, providing vertical support for the entire shelving unit and ensuring its structural stability when bearing goods and cold storage units. The multiple layers of beams 7 are horizontally arranged and vertically connected to the uprights, forming multiple storage planes and providing a supporting foundation for goods storage and cold storage unit installation. The spacing between opposing beams on the same layer is precisely designed according to the dimensions and specifications of the cold storage units and goods.

[0054] Several cold storage units are arranged between two opposing crossbeams 7 on the same floor. Each cold storage unit includes two longitudinal rods and several cold storage boxes 8. The cold storage boxes 8 are installed along the length of the two longitudinal rods, and the two ends of the longitudinal rods are connected to the crossbeams 7 by means of hangers 9.

[0055] The top plate 15 of the cold storage is equipped with several fixing components, and several cold storage boxes 8 are threaded through the cold storage box connectors of the fixing components. The hanging component 9 is an L-shaped plate, the horizontal part of which can be erected on the crossbeam 7, and the vertical part is provided with through holes for the longitudinal rods to pass through.

[0056] The fixed components on the cold storage roof work in conjunction with the cold storage units to further enhance the stability and controllability of the cold storage system. When significant temperature fluctuations occur inside the cold storage, the cold storage units and the cold storage boxes on the fixed components work together to store and release cold energy throughout the cold storage space through the phase change process of the phase change material. Hanging components connect the cold storage units to the shelf beams, while the fixed components are connected to the cold storage roof via a hoisting structure. Both components provide fixation and support to the cold storage boxes from different directions, ensuring the stability of the cold storage boxes during cold storage operation.

[0057] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the substantive content of this utility model.
