[0002] With the development of cold chain logistics and low-temperature storage technologies, various types of cold storage equipment have emerged, which use cold storage media (such as hydrated salts, ice crystals, etc.) to store and release energy in order to meet the cooling needs of different scenarios.

[0003] In related technologies, cold storage equipment is mostly of a fixed structure, which prevents the cold storage medium from being flexibly adjusted according to actual needs, greatly limiting its efficiency. Although some cold chain transport containers are equipped with replaceable cold storage plates, the process of moving and replacing them is cumbersome, increasing operational difficulty and affecting overall efficiency. In addition, current cold storage devices lack a mobile and easily deployable design, making it difficult to meet emergency or temporary cooling needs.

[0004] Existing cold storage equipment suffers from problems such as cumbersome installation and replacement of cold storage media and lack of portability. Utility Model Content

[0016] In one embodiment, a support member is also included, which is laterally disposed below the support frame and fixed between the two side supports, with the bottom of the cold storage plate abutting against the support member.

[0017] In one embodiment, the support member is a long strip rod-like structure or a rectangular plate-like structure; adjacent cold storage plates are limited and fixed by annular spacers.

[0018] In one embodiment, a baffle is also included, with two baffles respectively disposed laterally on the outside of the support frame, and a gap between the baffles and the cold storage plate.

[0035] See Figure 1 , Figure 1 A schematic diagram of the structure of a portable cold storage device according to an embodiment of this application is shown. Figure 1 .

[0036] One embodiment of this application provides a portable cold storage device, including a base 10, a frame assembly 20, multiple cold storage plates 30, and a connector 23, which realizes the functions of efficient cold storage and convenient mobility.

[0037] In this embodiment, a movable component is provided at the bottom of the base 10. The frame assembly 20 is fixed to the base 10 and includes a horizontally arranged support frame 21, longitudinally arranged support members 22 on both sides of the support frame 21, and a connecting member 23 horizontally arranged above or below the support frame 21. A plurality of cold storage plates 30 are arranged at lateral intervals within the support frame 21; the connecting member 23 passes through the plurality of cold storage plates 30 and is fixed between the two side support members 22.

[0038] The base 10, which serves as the support for the entire device, is made of a high-strength, low-temperature-resistant metal material, such as stainless steel. The base 10 is shaped like a rectangle or an I-beam to provide a larger support area.

[0039] The base 10 has a moving component at its bottom. The moving component uses casters 12 and directional wheels 13 with braking function. The two casters 12 and the two directional wheels 13 are respectively located at the bottom of the base 10 to facilitate the movement and turning of the cold storage device in different directions.

[0040] The frame assembly 20 is fixed on the base 10. The frame assembly 20 consists of a horizontally arranged support frame 21, longitudinally arranged support members 22 on both sides of the support frame 21, and a horizontally arranged connecting member 23 above or below the support frame 21.

[0041] The support frame 21 is arranged horizontally to support multiple cold storage plates 30. The width and length of the support frame 21 match the dimensions of the cold storage plates 30 to ensure that the cold storage plates 30 can be stably placed within the support frame 21. A certain gap is left between the cold storage plates 30 and the support frame 21, as well as between the multiple cold storage plates 30, to facilitate air circulation and improve cold storage efficiency.

[0042] Support members 22 are located on both sides of the support frame 21. One end of the support member 22 is embedded in the base 10 and fixedly connected by bolts. The height of the support member 22 is related to the height of the cold storage plate 30 and the number of layers of the cold storage plate 30 installed in the frame assembly 20.

[0043] The connector 23 is located above or below the support frame 21. Taking the connector 23 located above the support frame 21 as an example, both ends of the connector 23 are fixed to the support members 22 on both sides by bolts, and the middle part passes through multiple cold storage plates 30, serving to fix the cold storage plates 30. The connector 23 can increase the rigidity and stability of the frame assembly 20 and improve the installation stability of the cold storage plates 30.

[0044] Multiple cold storage plates 30 are arranged laterally at intervals within the support frame 21. The cold storage plates 30 are made of HDPE material and filled with a cold storage medium. The cold storage medium is a phase change material, such as hydrated salt or ice crystals. The outer shell of the cold storage plate 30 has a raised structure to increase the heat exchange area and improve its thermal conductivity. The cold storage plates 30 can absorb cold energy in a -18°C cold storage environment and release cold energy in a refrigerated environment of 0°C-8°C.

[0045] The cold storage plate 30 is a rectangular flat plate. The width of the cold storage plate 30 is slightly smaller than the width of the support frame 21, that is, there is a gap between the cold storage plate 30 and the support frame 21 to facilitate air circulation and improve cold storage efficiency.

[0046] In practice, a portable cold storage device is placed in a freezer, where it absorbs ambient cold through the cold storage medium inside the cold storage plates 30. Smooth airflow between the cold storage plates 30 allows for rapid and uniform absorption of cold, improving cold storage efficiency. When the cold storage device needs to release cold, workers can use the movable parts on the base 10 to move it to a cold storage room or other areas requiring cooling. During the release process, the cold storage medium in the cold storage plates 30 gradually releases cold, providing the necessary low-temperature conditions to the surrounding environment.

[0047] As shown above, multiple cold storage plates 30 are placed horizontally at intervals within the support frame 21, and connectors 23 are inserted through the cold storage plates 30 and fixed to the support members 22, thus achieving the installation and fixation of the cold storage plates 30. The overall structure is simple and easy to install and disassemble. At the same time, the cold storage device is movable, easy to deploy and transport, which helps to improve cold storage efficiency and thus improve the user experience.

[0048] Combination Figure 2 , Figure 3 As shown, Figure 2 This is a schematic diagram of the structure of a portable cold storage device provided in one embodiment of this application. Figure 2 . Figure 3 This is a schematic diagram of the structure of a portable cold storage device provided in one embodiment of this application. Figure 3 In some embodiments, the support frame 21 is a long strip frame structure, and the support member 22 is a rectangular rod structure. Multiple layers of the support frame 21 are arranged at intervals along the longitudinal direction; at least two of the support members 22 are spaced apart on the same side of the support frame 21.

[0049] Specifically, the support frame 21 is a long, rectangular frame structure made of welded square tubing. The square tubing can be made of metal, such as aluminum alloy. This ensures that the support frame 21 will not deform or be damaged during long-term use, while also reducing the overall weight of the support frame 21.

[0050] The multiple layers of support frames 21 are arranged longitudinally at intervals, with a gap between each layer of support frames 21 to ensure sufficient space for air circulation between the cold storage plates 30, thereby improving the efficiency of cold storage and release. For example, in this embodiment, three layers of support frames 21 are provided.

[0051] The support member 22 is a rectangular rod-shaped structure made of metal, such as aluminum alloy. At least two support members 22 are spaced apart and arranged on the same side of the support frame 21. In this embodiment, four support members 22 are provided, two of which are fixed at one end to the base 10 by bolts, and the other end is connected to the support frame 21 by bolts, which facilitates installation and disassembly.

[0052] In one embodiment, there are at least two connectors 23, which are arranged diagonally in the longitudinal direction.

[0053] Specifically, this embodiment employs two circular rod-shaped connectors 23, which are arranged diagonally in the longitudinal direction. The connectors 23 can be made of metal, such as aluminum alloy, which is resistant to deformation or breakage under significant external forces. The circular rod-shaped design allows the connectors 23 to pass through the cold storage plate 30 more smoothly, reducing friction between them.

[0054] In one embodiment, the connector 23 is a circular rod-shaped structure, and the cold storage plate 30 has at least two through holes 31 arranged diagonally; the connector 23 passes through the through holes 31 provided on the multiple cold storage plates 30 respectively.

[0055] Specifically, the cold storage plate 30 has at least two through holes 31. In this embodiment, two through holes 31 are provided and are arranged diagonally. The diameter of the through holes 31 is set according to the diameter of the connector 23, and is slightly larger than the diameter of the connector 23 to ensure that the connector 23 can be easily inserted.

[0056] In one embodiment, the support member 22 is provided with a mounting hole 221 at a position corresponding to the through hole 31 of the cold storage plate 30, and both ends of the connector 23 are respectively fixed in the mounting hole 221 by bolts.

[0057] Specifically, the connectors 23 are respectively inserted through the through holes 31 on the multiple cold storage plates 30, connecting the cold storage plates 30 on the support frame 21 in series. The support member 22 is provided with mounting holes 221 at the positions corresponding to the through holes 31 on the cold storage plates 30, and both ends of the connectors 23 are fixed in the mounting holes 221 by bolts.

[0058] During installation of the cold storage plate 30, the connector 23 is first inserted through the mounting hole 221 of one support member 22, then sequentially through the through holes 31 of each layer of the cold storage plate 30, and finally exits through the mounting hole 221 of another support member 22. The two ends of the connector 23 are then securely fixed with bolts. This diagonally arranged connector 23 allows for fixing of the cold storage plate 30 from different directions, thereby enhancing the overall stability and torsional resistance of the device.

[0059] The number and diameter of the through holes 31 of the cold storage plate 30, the number, shape and diameter of the connectors 23, as well as the external and internal structures of the cold storage plate 30 can all be adapted to specific usage requirements, and will not be elaborated here.

[0060] Combination Figure 2 As shown, Figure 2 This is a schematic diagram of the structure of a portable cold storage device provided in one embodiment of this application. Figure 2 .

[0061] In some embodiments, a support member 24 is also included, which is laterally disposed below the support frame 21 and fixed between the two side supports 22, and the bottom of the cold storage plate 30 abuts against the support member 24.

[0062] Specifically, the support member 24 is horizontally positioned below the support frame 21 and fixed between the two side support members 22. The support member 24 is used to abut against the bottom surface of the cold storage plate 30, providing auxiliary support and ensuring the stability of the cold storage plate 30 during movement. The spacing between the support members 24 is smaller than the width of the cold storage plate 30 to ensure sufficient contact area between the support member 24 and the bottom of the cold storage plate 30, thus ensuring the supporting effect.

[0063] In one embodiment, the support member 24 is a long strip rod-shaped structure or a rectangular plate-shaped structure; adjacent cold storage plates 30 are limited and fixed by annular spacers.

[0064] Specifically, the support component 24 is a long, rod-shaped structure or a rectangular plate-shaped structure. The support component 24 is made of metal, such as aluminum alloy, to ensure that the support component 24 has sufficient strength to support the cold storage plate 30.

[0065] The adjacent cold storage plates 30 are fixed by a ring-shaped spacer to prevent the cold storage plates 30 from shifting when the cold storage device is moved, thus ensuring the connection stability between adjacent cold storage plates 30 and ensuring its cold storage effect.

[0066] The support member 24 is fixed to the outside of the two support members 22 by bolts, so as to avoid occupying the internal space of the support frame 21, ensuring the capacity of the support frame 21, so as to place more cold storage plates 30, thereby improving the cold storage effect.

[0067] In one embodiment, a baffle 25 is also included, with two baffles 25 disposed laterally on the outer side of the support frame 21, and a gap between the baffles 25 and the cold storage plate 30.

[0068] Specifically, two baffles 25 are respectively arranged laterally on the outside of the support frame 21. The baffles 25 are made of stainless steel or aluminum alloy. The baffles 25 are connected to the outside of the support frame 21 by welding or bolting.

[0069] A gap exists between the baffle 25 and the cold storage plate 30 to ensure smooth airflow between them while preventing the baffle 25 from excessively affecting the heat exchange of the cold storage plate 30. The size of the gap is determined based on the airflow requirements within the device and the heat exchange efficiency of the cold storage plate 30.

[0070] In one embodiment, a portion of the baffle 25 is provided with a plurality of spaced through slots 251, and the through slots 251 on two oppositely arranged baffles 25 are correspondingly arranged.

[0071] Specifically, a portion of the baffle 25 has multiple spaced through slots 251, which are rectangular or elliptical in shape. The through slots 251 on two opposing baffles 25 are arranged correspondingly, allowing air to flow between the corresponding through slots 251, thereby improving the heat exchange efficiency between the cold storage plate 30 and the air.

[0072] The shape and size of the through groove 251 can be adapted to meet specific usage requirements.

[0073] In one embodiment, a handle 40 is also included, which is fixed to the support 22.

[0074] Specifically, the handle 40 can be made of metal, such as aluminum alloy. The handle 40 is U-shaped, and one side of the handle 40 is fixed to the support 22 by bolts. When the operator needs to move the cold storage device, he only needs to hold the handle 40 with both hands and apply a certain force to easily push the device to move in the horizontal direction.

[0075] In one embodiment, the surface of the base 10 is provided with a downwardly recessed mounting groove 11.

[0076] Specifically, the base 10 has a recessed mounting groove 11 on its surface. The mounting groove 11 is rectangular in shape, and its length and width are designed according to the size of the cold storage plate 30 installed below. The cold storage plate 30 at the bottom of the cold storage device abuts against the upper edge of the mounting groove 11. The mounting groove 11 can collect condensate dripping from the surface of the cold storage plate 30 when the cold storage plate 30 releases cold energy, preventing condensate from flowing out, ensuring the cleanliness of the cold storage device and improving the user experience.

[0077] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
