Description

Technical Field

[0001] This application relates to the field of cold chain modular container technology, and more specifically, to an insulation structure for a medical mobile cold chain modular container and the medical mobile cold chain modular container itself. Background Technology

[0002] In the pharmaceutical cold chain transportation sector, mobile medical cold chain containers serve as key equipment for drug transport, and their technological development continues to optimize in response to the growing demands of the medical industry. Innovations in insulation structures aim to improve temperature stability, adapt to diverse transportation scenarios, and drive the industry towards greater efficiency and reliability. Related research focuses on material improvements and structural design to meet increasingly stringent temperature control standards.

[0003] However, in high-temperature transportation environments, existing mobile cold chain medical containers typically achieve insulation by adding an ice pack inside a foam-lined outer casing. This single ice pack insulation structure suffers from poor insulation performance; its insulation capacity weakens significantly at high temperatures, failing to effectively isolate external heat. This leads to frequent temperature fluctuations inside the container, easily exceeding the stringent requirements for pharmaceutical cold chain transportation. This temperature instability increases the risk of drug deterioration, potentially causing reduced efficacy or safety hazards. Furthermore, this structure has a shortened insulation time, failing to meet the needs of long-distance or extreme environments, further limiting the reliability and application scope of the cold chain system. These problems highlight the urgent need to improve insulation technology to ensure drug quality and transportation safety.

[0004] There is currently no effective technical solution to the above problems. Utility Model Content

[0005] The purpose of this application is to provide an insulation structure for a mobile medical cold chain container and the mobile medical cold chain container itself, so as to enhance the insulation performance and temperature stability in high-temperature environments by constructing a double-layer ice pack insulation structure, extend the effective insulation time of the container, and thus ensure the quality and safety of medical supplies during transportation.

[0006] In a first aspect, this application provides an insulation structure for a mobile medical cold chain container, installed inside the mobile medical cold chain container. The mobile medical cold chain container includes an outer casing and an inner casing installed inside the outer casing. The insulation structure of the mobile medical cold chain container includes:

[0007] The first ice pack is installed between the outer and inner boxes;

[0008] The second ice pack is assembled inside the interlayer of the inner box.

[0009] The medical mobile cold chain container of this application has a double-layer ice pack insulation structure. The first ice pack blocks most of the external heat on the outer layer, reducing the insulation pressure on the inner box, while the second ice pack provides continuous cooling on the inner layer, precisely controlling the temperature of the inner box. This double-layer ice pack design effectively enhances the insulation performance and temperature stability in high-temperature environments, reduces temperature fluctuations inside the inner box, and extends the effective insulation time of the container.

[0010] The insulation structure of the aforementioned medical mobile cold chain container includes a first ice pack filled with a first insulation material and a second ice pack filled with a second insulation material. The phase change temperature of the first insulation material is lower than that of the second insulation material.

[0011] This application creates a synergistic insulation system by placing phase change materials with different phase change temperatures within inner and outer ice layers, and by combining the structure and positional relationship of the ice layers. The outer ice layer preferentially absorbs external heat, reducing the heat load transferred to the inner ice layer, while the inner ice layer is responsible for maintaining the precise temperature inside the enclosure. This mechanism of internal and external division of labor and synergistic heat absorption significantly improves the adaptability and effectiveness of the insulation structure in high-temperature environments, solving the problems of rapid performance degradation and large temperature fluctuations of single ice layers or ice layers made of the same phase change material at high temperatures.

[0015] The insulation structure of the medical mobile cold chain cabin includes a plurality of evenly distributed cooling holes on the first ice pack, and a handle for easy pulling out on the first ice pack.

[0016] The insulation structure of the medical mobile cold chain container includes an inner box with a panel shell and a second ice pack and a foam layer assembled inside the panel shell. The second ice pack and the foam layer are located on the side closer to the inside of the inner box and the side closer to the outside of the inner box, respectively.

[0017] The insulation structure of the medical mobile cold chain cabin includes an inner panel and an outer panel, which are arranged inside and outside, and a door seal that is snapped together between the inner panel and the perimeter of the panel. The second ice pack is attached to the inner panel, and the foam layer is attached to the outer panel.

[0018] The insulation structure of the medical mobile cold chain cabin includes, in part, a bent barrier sheet fixed to the outer panel for separating the second ice pack and the foam layer installation position.

[0019] Secondly, this application also provides a mobile medical cold chain container, which includes an outer box, an inner box installed inside the outer box, and an insulation structure for the mobile medical cold chain container as described in the first aspect.

[0020] The medical mobile cold chain container of this application adopts an improved insulation structure, which combines the installation of a first ice pack between the outer and inner boxes with the assembly of a second ice pack in the interlayer of the inner box to construct a double-layer ice pack insulation structure. This double-layer ice pack design effectively enhances the insulation performance and temperature stability in high-temperature environments, reduces temperature fluctuations inside the inner box, and extends the effective insulation time of the container, thereby ensuring the quality and safety of medical supplies during transportation.

[0021] As can be seen from the above, this application provides an insulation structure for a medical mobile cold chain container and a medical mobile cold chain container. The insulation structure of the medical mobile cold chain container of this application combines the installation of a first ice pack between the outer and inner boxes with the assembly of a second ice pack in the interlayer of the inner box, thereby constructing a double-layer ice pack insulation structure. The first ice pack blocks most of the external heat on the outer layer, reducing the insulation pressure on the inner box, while the second ice pack provides continuous cooling on the inner layer, precisely controlling the temperature of the inner box. This double-layer ice pack design effectively enhances the insulation performance and temperature stability in high-temperature environments, reduces temperature fluctuations inside the inner box, and extends the effective insulation time of the container, thereby ensuring the quality and safety of medical supplies during transportation.

[0033] Firstly, please refer to Figures 1-4 This application provides an insulation structure for a mobile medical cold chain container, installed inside the mobile medical cold chain container. The mobile medical cold chain container includes an outer box 1 and an inner box 2 installed inside the outer box 1. The insulation structure of the mobile medical cold chain container includes:

[0034] The first ice block 3 is installed between the outer box 1 and the inner box 2;

[0035] The second ice block 4 is assembled in the interlayer of the inner box 2.

[0036] Specifically, the first ice pack 3 refers to a cold storage unit used to store cold energy and release it through phase change or sensible heat. It can be implemented in various forms, such as a plastic container filled with phase change material, a gel pack, or a modular plate structure. Its main purpose is to create a low-temperature zone between the outer box 1 and the inner box 2, blocking external heat transfer to the inner box 2. "Installed between the outer box 1 and the inner box 2" means that the first ice pack 3 is placed in the space between the outer shell and the internal container of the medical mobile cold chain cabin, allowing it to preferentially absorb heat transferred from the external environment.

[0037] More specifically, the second ice pack 4 refers to another cold storage unit used to store and release cold energy. It can take a similar or different form from the first ice pack 3, such as a flat container or flexible bag suitable for embedding in the interlayer. Its main purpose is to provide a continuous cold source inside the inner box 2 and maintain the temperature stability of the inner box 2. "Assembled in the interlayer of the inner box 2" means that the second ice pack 4 is integrated into or placed in the internal structural layer of the inner box 2 wall to provide temperature control closer to the goods.

[0038] More specifically, the mobile medical cold chain container consists of an outer box 1 and an inner box 2 installed inside the outer box 1. A first ice block 3 is arranged in the space between the outer box 1 and the inner box 2. When the external ambient temperature is high, heat is transferred from the outside to the inside, first reaching the outer box 1, and then attempting to pass through the space between the outer box 1 and the inner box 2. The first ice block 3, located in this space, absorbs this heat, consuming thermal energy through its phase change or temperature increase, thereby forming a lower-temperature buffer zone between the outer box 1 and the inner box 2, significantly reducing the heat transferred to the inner box 2. A second ice block 4 is integrated into the sandwich structure of the inner box 2 itself. A small amount of residual heat passing through the space between the first ice block 3 and the outer and inner boxes 1, as well as heat that may be generated inside the inner box 2, is transferred to the wall of the inner box 2. The second ice block 4, located in the sandwich structure of the inner box 2, absorbs this heat, directly cooling the internal space of the inner box 2 and maintaining the internal temperature of the inner box 2 within the required range. Through the synergistic effect of these inner and outer ice layers, external heat is blocked and absorbed in stages, allowing the temperature of the inner chamber 2 to remain stable for a longer period of time, thus improving the overall performance of the insulation structure.

[0039] The insulation structure of the medical mobile cold chain container of this application combines the installation of a first ice block 3 between the outer box 1 and the inner box 2 with the assembly of a second ice block 4 in the interlayer of the inner box 2, thereby constructing a double-layer ice block insulation structure. The first ice block 3 blocks most of the external heat on the outer layer, reducing the insulation pressure on the inner box 2, while the second ice block 4 provides continuous cooling on the inner layer, precisely controlling the temperature of the inner box 2. This double-layer ice block design effectively enhances the insulation performance and temperature stability in high-temperature environments, reduces temperature fluctuations inside the inner box 2, and extends the effective insulation time of the container, thereby ensuring the quality and safety of medical supplies during transportation.

[0040] In some preferred embodiments, the first ice pack 3 is filled with a first insulating material, and the second ice pack 4 is filled with a second insulating material, wherein the phase change temperature of the first insulating material is lower than that of the second insulating material.

[0041] Specifically, the first insulation material refers to the material with phase change heat absorption capacity filled inside the first ice block 3; the second insulation material refers to the material with phase change heat absorption capacity filled inside the second ice block 4; both the first and second insulation materials can be organic phase change materials, inorganic phase change materials, or their composite materials; the phase change temperature refers to the temperature at which a material undergoes a phase change (usually a solid-liquid phase change) under a specific pressure. During this process, the material absorbs or releases a large amount of latent heat. The phase change material with a suitable phase change temperature can be selected according to the actual required insulation temperature range and external environmental conditions. For example, the main component of the first insulation material is water, and the main component of the second insulation material is paraffin wax, so that the phase change temperature of the first insulation material is lower than that of the second insulation material.

[0042] More specifically, the first ice pack 3 is located between the outer box 1 and the inner box 2, closer to the external environment; the second ice pack 4 is located within the interlayer of the inner box 2, closer to the interior of the box. When the external ambient temperature rises, heat is first transferred to the first ice pack 3. Based on the setting that the phase change temperature of the first insulation material is lower than that of the second insulation material, the first insulation material within the first ice pack 3 undergoes a phase change before the second insulation material within the second ice pack 4, absorbing a large amount of external heat and thus hindering heat transfer to the inner box 2. After the first insulation material has completely undergone phase change, heat continues to transfer inward, reaching the second ice pack 4. At this point, the second insulation material within the second ice pack 4, due to its higher phase change temperature, is still in the process of phase change or has not yet completely changed phase, continuing to absorb heat and maintain the temperature of the inner box 2. This staged phase change heat absorption process utilizes the characteristics of materials with different phase change temperatures, forming a temperature gradient and a heat absorption barrier, making it difficult for external heat to penetrate quickly, thereby extending the insulation time and helping to maintain the internal temperature of the inner box 2 within a narrower range, improving the overall performance of the insulation structure.

[0043] This application creates a synergistic insulation system by placing phase change materials with different phase change temperatures within inner and outer ice layers, and by combining the structure and positional relationship of the ice layers. The outer ice layer preferentially absorbs external heat, reducing the heat load transferred to the inner ice layer, while the inner ice layer is responsible for maintaining the precise temperature inside the enclosure. This mechanism of internal and external division of labor and synergistic heat absorption significantly improves the adaptability and effectiveness of the insulation structure in high-temperature environments, solving the problems of rapid performance degradation and large temperature fluctuations of single ice layers or ice layers made of the same phase change material at high temperatures.

[0044] In some preferred embodiments, such as Figure 3 As shown, the first ice block 3 covers the four inner side walls and the inner top wall of the outer box 1.

[0045] Specifically, covering refers to arranging or fixing the first ice block 3 near the inner surfaces of the four inner side walls and the inner top wall of the outer casing 1, and extending along these surfaces to form a thermal resistance layer. This can be achieved by arranging and combining multiple first ice block 3 units or by using first ice blocks 3 of a custom shape.

[0046] More specifically, the above arrangement allows the first ice block 3 to directly handle the heat load from the sides and top, areas that are often the main pathways for heat transfer in high-temperature environments, especially the top wall which may be exposed to direct sunlight. By placing the first ice block 3 in these critical locations, the total heat entering the space between the outer box 1 and the inner box 2 is reduced, thereby reducing the heat reaching the inner box 2 and the second ice block 4.

[0047] In some preferred embodiments, the first ice pack 3 covering the four inner side walls of the outer box 1 is one layer, and the first ice pack 3 covering the inner top wall of the outer box 1 is two layers.

[0048] Specifically, such as Figure 2 As shown, each layer of first ice floes 3 is composed of multiple linear arrays of first ice floes 3. Two layers refer to laying two layers of first ice floes 3 on a specific surface, and the two layers of ice floes can be stacked on top of each other.

[0049] This solution addresses the issue of providing differentiated insulation capabilities in areas with varying heat loads by varying the number of layers of the first ice pack 3 at different locations. The four inner side walls of the outer casing 1 are covered with one layer of the first ice pack 3, providing basic lateral insulation. The inner top wall of the outer casing 1 is covered with two layers of the first ice pack 3, significantly enhancing the insulation and cold storage capacity of this area by increasing the thickness of the top insulation layer. Since the top wall is typically more susceptible to external heat sources, increasing the number of ice pack layers at the top more effectively blocks heat from entering, maintaining a stable internal temperature within the container.

[0050] In some preferred embodiments, the first ice pack 3 is detachably installed inside the outer casing 1.

[0051] Specifically, the first ice block 3 can be detached and installed using methods such as snap-fit ​​connection, slide rail cooperation, magnetic adsorption, bolt connection and easy-to-operate fasteners.

[0052] More specifically, by designing the first ice pack 3 as a detachable installation method, it can be easily and quickly removed from the outer casing 1 and replaced with a new, pre-cooled ice pack when its cold storage capacity decreases due to ambient temperature or transportation time during transport. This design overcomes the difficulty of replacing ice packs under fixed installation methods, allowing the insulation structure to continuously provide insulation capacity by replacing the cold storage unit. This detachability, combined with the specific position of the first ice pack 3 between the outer casing 1 and the inner casing 2, ensures that when additional cooling is needed, it can quickly and effectively act on the key areas of the insulation structure, thereby maintaining the stability of the internal temperature of the container and extending the effective insulation time of the medical mobile cold chain cabin.

[0053] In some preferred embodiments, such as Figure 4 As shown, the first ice block 3 is provided with a plurality of evenly distributed cooling holes 31, and the first ice block 3 is provided with a handle 32 for easy pulling.

[0054] Specifically, the cooling vent 31 refers to a through hole or porous structure provided on the outer shell of the first ice block 3, used to control and guide the rate and direction of cold release from the internal cold storage material of the first ice block 3. It can be implemented in the form of circular holes, square holes, slits, or microporous membranes. The handle 32 refers to a structure provided on or connected to the body of the first ice block 3, which facilitates the user's grip and application of force. It can be implemented in the form of an integrally formed protrusion, an additional pull ring, a groove, or a folding handle.

[0055] More specifically, multiple evenly distributed cooling holes 31 are provided on the first ice block 3, so that the cold energy of the first ice block 3 can be more evenly distributed to the space between the outer box 1 and the inner box 2 through these holes. This avoids local overcooling or insufficient cold areas caused by concentrated release of cold energy, and helps to form a more stable and uniform low temperature environment in this space. This more effectively blocks the transfer of external heat to the inner box 2, and improves the stability and reliability of the insulation effect.

[0056] More specifically, a handle 32 is provided on the first ice block 3 for easy pulling, providing users with a convenient point of grip and force application, making the operation of pulling out or pushing in the first ice block 3 from the outer box 1 more effortless, quick, and safe. This handle 32, combined with the detachable installation feature of the first ice block 3, greatly improves the convenience of ice block replacement or pre-cooling processes, shortens operation time, and reduces operation difficulty.

[0057] In some preferred embodiments, such as Figure 2 As shown, the interlayer of the inner box 2 includes: a panel shell 21 and a second ice pack 4 and a foam layer 22 assembled inside the panel shell 21. The second ice pack 4 and the foam layer 22 are located on the side closer to the inside of the inner box 2 and the side closer to the outside of the inner box 2, respectively.

[0058] Specifically, the panel shell 21 refers to the structure that forms the outer boundary of the inner box 2 interlayer, which can be realized by using a one-piece molded plastic shell or by using a structure assembled from multiple panels. The foam layer 22 refers to a porous material layer with low thermal conductivity, which can be realized by using materials such as polyurethane foam, polystyrene foam, or vacuum insulation panels.

[0059] More specifically, the panel housing 21 provides support and encapsulation for the components within the interlayer. The foam layer 22 is positioned near the exterior of the inner casing 2, its function being to impede heat transfer from the external environment into the inner casing 2. The second ice pack 4 is positioned near the interior of the inner casing 2, closer to the internal space of the inner casing 2 where a low temperature needs to be maintained. A small amount of heat entering the interlayer is absorbed by the second ice pack 4 after passing through the foam layer 22, and the second ice pack 4 utilizes its phase change properties to maintain the internal temperature of the inner casing 2 within a set range. This layered arrangement and functional combination—the foam layer 22 impeding heat transfer, and the second ice pack 4 absorbing heat and maintaining temperature—reduces the impact of the high-temperature external environment on the internal temperature of the inner casing 2. The first ice pack 3 reduces the heat load on the outer layer, thus lowering the rate of heat transfer faced by the foam layer 22 and the second ice pack 4 within the interlayer of the inner casing 2, thereby extending the time the second ice pack 4 maintains its temperature and enhancing the ability of the inner casing 2 to maintain its internal temperature within a set range.

[0060] In some preferred embodiments, the panel housing 21 includes: an inner panel 211 and an outer panel 212 disposed inside and outside, and a door seal 213 that snaps together the inner panel 211 and the periphery of the panel; a second ice pack 4 is disposed in contact with the inner panel 211; and a foam layer 22 is disposed in contact with the outer panel 212.

[0061] Specifically, the inner panel 211 refers to the plate-like structure on the side of the panel housing 21 closest to the interior of the inner box 2. The outer panel 212 refers to the plate-like structure on the side of the panel housing 21 closest to the exterior of the inner box 2. A snap-fit ​​connection refers to a detachable or semi-permanent fixation between two or more components achieved through an elastic or mechanical locking structure. A door seal 213 refers to a flexible or semi-flexible strip-like seal installed on the edge of the panel to fill gaps and prevent the flow of gas or liquid.

[0062] More specifically, the inner panel 211 and the outer panel 212 constitute the main structure of the panel shell 21, defining the space of the interlayer. The inner panel 211 is located on the inside, and the outer panel 212 is located on the outside. This layered structure provides an installation interface for the internal insulation components. The door seal 213 is connected to the edge of the inner panel 211 and surrounds the panel by a snap-fit ​​method. When the panel shell 21 is assembled, the door seal 213 forms a sealed fit with the outer panel 212 or other structures of the inner box 2. This snap-fit ​​connection method facilitates assembly and disassembly. At the same time, the door seal 213 effectively fills the gaps at the edge of the panel, blocking the "thermal bridge" formed by heat convection or conduction, and enhancing the sealing performance of the panel shell 21 itself.

[0063] More specifically, the second ice pack 4 is arranged and adhered to the inner surface of the inner panel 211, making it adjacent to the internal space of the inner chamber 2, enabling efficient release of cooling capacity into the chamber. The foam layer 22 is arranged and adhered to the inner surface of the outer panel 212, making it adjacent to the external environment, utilizing the low thermal conductivity of the foam material to block the ingress of external heat. This layout, with its separate inner and outer layers each fulfilling its specific function, combined with the structure and sealing design of the panel shell 21, ensures the stable position and effective functioning of the second ice pack 4 and the foam layer 22 within the interlayer.

[0064] More specifically, unlike simply placing components in the interlayer, the aforementioned structure provides clear support and positioning, and achieves effective edge sealing through the door seal 213, reducing heat loss. This structural improvement, combined with the overall insulation strategy of incorporating a second ice pack 4 and a foam layer 22 in the inner box 2 interlayer, enhances the insulation performance of the inner box 2, especially in the face of external temperature changes and vibrations during transportation, better maintaining the stability of the internal temperature of the inner box 2.

[0065] In some preferred embodiments, such as Figure 2 As shown, the panel housing 21 also includes a bent barrier sheet 214 fixed to the outer panel 212 for separating the installation positions of the second ice pack 4 and the foam layer 22.

[0066] Specifically, the bent barrier sheet 214 refers to a sheet-like component that is bent and fixed to the outer panel 212 to form a physical separation structure inside the panel shell 21.

[0067] More specifically, the bent barrier 214 is fixed to the outer panel 212, and its function is to separate the installation space of the second ice pack 4 and the foam layer 22. When the second ice pack 4 and the foam layer 22 are filled or assembled into the panel shell 21, the bent barrier 214 acts as a physical barrier, effectively isolating the two and preventing them from interfering with each other or becoming displaced. This separation ensures that the second ice pack 4 can be stably fitted to the inner panel 211, and the foam layer 22 can be stably fitted to the outer panel 212, thereby ensuring the stability and reliability of the internal structure of the inner box 2. This stable structure allows the foam layer 22 to continuously and effectively provide thermal insulation, while the second ice pack 4 can stably insulate the interior of the box. The functions of both are fully utilized, and due to their fixed positions, the attenuation or instability of the thermal insulation effect caused by displacement is avoided, maintaining the stability of the internal temperature of the box. In this way, the solution enhances the reliability of the inner box's double-layer insulation structure and improves the overall insulation effect of the medical mobile cold chain cabin.

[0068] Secondly, please refer to Figure 5 Some embodiments of this application also provide a mobile medical cold chain container, which includes an outer box 1, an inner box 2 installed inside the outer box 1, and an insulation structure for the mobile medical cold chain container as provided in the first aspect.

[0069] The medical mobile cold chain container of this application adopts an improved insulation structure. It combines the installation of a first ice block 3 between the outer box 1 and the inner box 2 with the assembly of a second ice block 4 in the interlayer of the inner box 2, thereby constructing a double-layer ice block insulation structure. The first ice block 3 blocks most of the external heat on the outer layer, reducing the insulation pressure on the inner box 2, while the second ice block 4 provides continuous cooling on the inner layer, precisely controlling the temperature of the inner box 2. This double-layer ice block design effectively enhances the insulation performance and temperature stability in high-temperature environments, reduces temperature fluctuations inside the inner box 2, and extends the effective insulation time of the container, thereby ensuring the quality and safety of medical supplies during transportation.
