[0001] This application relates to the field of cold storage technology, and in particular to a cold storage block and a cold storage structure. Background Technology

[0002] Cold storage blocks serve a cooling function. They are filled with a refrigerant. When the refrigerant melts from a frozen state to a liquid state, a thin air layer forms between the refrigerant and the inner wall of the block. The air in this air layer has an extremely low thermal conductivity. This air layer hinders the transfer of cold energy, thus significantly reducing the cooling effect of the cold storage block. Utility Model Content

[0003] This application provides a cold storage block and a cold storage structure to solve the technical problem that the air layer in the cold storage block will hinder the transfer of cold energy, thereby causing a significant reduction in the cold storage effect of the cold storage block.

[0005] Among them, the cooling conductive component extends along the first direction and is connected to the second housing, and multiple cooling conductive components are arranged in an array along the second direction, which is different from the first direction.

[0006] Wherein, the first housing is a plastic housing, the second housing is a metal housing or an alloy housing; and / or, the cooling component is a metal cooling component or an alloy cooling component.

[0007] The second housing insert is injection molded onto the first housing.

[0008] The first housing has two first connecting parts arranged opposite each other along the second direction, and each first connecting part is provided with a plug-in groove; the second housing has two plug-in parts arranged opposite each other along the second direction, and the plug-in parts are plugged into the plug-in grooves.

[0009] The first protrusion is provided on one side of the plug-in portion facing the plug-in groove and the first recess is provided on the other side of the plug-in groove facing the plug-in portion, and the first protrusion is confined within the first recess.

[0010] The first housing has two second connecting parts arranged opposite each other along the first direction. The second connecting parts are provided with multiple snap-fit ​​grooves, and the end of the cooling component is snapped into the snap-fit ​​groove.

[0011] The second protrusion is provided on one side of the second connecting portion facing the second housing and on the other side of the second housing facing the second connecting portion, and the second recess is provided on the other side, with the second protrusion confined within the second recess.

[0012] Wherein, the depth of the second recess along the third direction is greater than or equal to 0.2 mm and less than or equal to 0.4 mm, and the third direction is different from the first direction; and / or, the width of the second recess along the second direction is greater than or equal to 0.5 mm and less than or equal to 1.5 mm, and the second direction is different from the first direction.

[0013] The first housing includes an outer shell and a first cover plate. The outer shell is provided with a second mounting port, which is disposed opposite to the first mounting port. The second housing includes a second cover plate, which is disposed opposite to the first cover plate. The first cover plate is connected to the outer shell and covers the second mounting port.

[0014] The cold storage block includes a sealing element; the first housing is provided with a liquid injection hole, which is connected to the receiving space, and the sealing element is connected to the liquid injection hole; the liquid injection hole and the second housing are arranged opposite to each other.

[0015] The ratio of the amount of refrigerant to the volume of the storage space is greater than or equal to 0.8 and less than or equal to 0.95.

[0016] To address the aforementioned technical problems, this application proposes a cold storage structure comprising multiple cold storage blocks as described above, wherein the multiple cold storage blocks can be spliced ​​together to form a planar or three-dimensional shape.

[0017] The cold storage blocks are square or rectangular.

[0018] The cold storage block has male connectors on two adjacent sidewalls and female connectors on two other adjacent sidewalls. The adjacent cold storage blocks are connected by interference fit between the male and female connectors.

[0019] This application's cold storage block includes a first shell, a second shell, and multiple cold-conducting components. The first shell has a first mounting opening. The second shell is connected to the first shell and covers the first mounting opening. A receiving space is formed between the second shell and the first shell. The receiving space is filled with a cold storage agent. The second shell is used to contact the component to be cooled. The multiple cold-conducting components are connected to the second shell and located within the receiving space. The cold-conducting components are in contact with the cold storage agent. The thermal conductivity of both the second shell and the cold-conducting components is greater than that of the first shell.

[0020] Through the combined action of the first shell, the second shell, and multiple heat-conducting components, when a partial air layer exists within the space containing the cold storage block, the heat-conducting components directly contact the cold storage agent, forming a heat exchange interface. Since the thermal conductivity of the second shell and the multiple heat-conducting components is greater than that of the first shell, the cold energy of the cold storage agent is transferred to the external environment through the heat-conducting components and the second shell. The second shell and the multiple heat-conducting components enhance the efficiency of cold energy transfer between the cold storage agent and the external environment, thereby improving the cold storage block's insulation effect and reducing the obstruction of cold energy transfer efficiency by the thin air layer.

Detailed Implementation

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] The following describes in detail the cold storage block and cold storage structure provided by this utility model with reference to the embodiments.

[0026] Please see Figure 1 , Figure 2 as well as Figure 3 , Figure 1 This is a first structural schematic diagram of an embodiment of the cold storage block of this application; Figure 2 This is an exploded schematic diagram of an embodiment of the cold storage block of this application; Figure 3This is a first cross-sectional schematic diagram of an embodiment of the cold storage block of this application. This application provides a cold storage block. The cold storage block 10 includes a first housing 11, a second housing 12, and a plurality of cooling conductive elements 14. The first housing 11 is provided with a first mounting port 1111. The second housing 12 is connected to the first housing 11 and covers the first mounting port 1111. A receiving space 13 is formed between the second housing 12 and the first housing 11. The receiving space 13 is filled with a cold storage agent (not shown in the figure). The second housing 12 is used to contact the component to be cooled. The plurality of cooling conductive elements 14 are connected to the second housing 12 and located in the receiving space 13. The cooling conductive elements 14 are in contact with the cold storage agent. The thermal conductivity of both the second housing 12 and the cooling conductive elements 14 is greater than that of the first housing 11.

[0027] The cold storage block 10 is used to contact the part to be cooled (not shown in the figure) to bring it to a low temperature. The cold storage block 10 can be used in outdoor portable cold storage and preservation applications. The first mounting port 1111 provides a mounting position for the second housing 12. The second housing 12 can be detachably or fixedly connected to the first housing 11. Detachment methods may include, but are not limited to, snap-fit ​​and plug-in connections. Fixing methods may include, but are not limited to, welding and bonding.

[0028] During the installation of the second housing 12 onto the first housing 11, the second housing 12 covers the first mounting opening 1111, and a receiving space 13 is formed between the second housing 12 and the first housing 11. This receiving space 13 is filled with a certain amount of cold storage agent. The cold storage agent is a phase change material. The cold storage agent can change from solid to liquid or from liquid to solid. During the phase change process, the cold storage agent absorbs or releases a large amount of latent heat, thereby achieving energy storage and release, and thus maintaining a low temperature. When the cold storage block 10 comes into contact with the part to be cooled, the end face of the second housing 12 facing away from the receiving space 13 is used to contact the part to be cooled, so that the part to be cooled is in a low temperature state.

[0029] Multiple cooling conductive elements 14 are used to conduct the cooling capacity of the refrigerant. The number of cooling conductive elements 14 can be, but is not limited to, two, three, four, or more than five. The cooling conductive elements 14 are detachably or fixedly connected to the end face of the second housing 12 facing the receiving space 13. The detachable method can be, but is not limited to, snap-fit ​​and plug-in. The fixed method can be, but is not limited to, welding and bonding. In this embodiment, the cooling conductive elements 14 are integrally formed into the second housing 12. When multiple cooling conductive elements 14 are installed on the end face of the second housing 12 facing the receiving space 13, all multiple cooling conductive elements 14 are located within the receiving space 13, which can break the continuity of the air layer, so that the multiple cooling conductive elements 14 are at least partially in contact with the refrigerant, thereby avoiding the formation of a complete low thermal conductivity air layer.

[0030] The thermal conductivity of the second housing 12 can be greater than that of the first housing 11, meaning the thermal conductivity of the second housing 12 is greater than that of the first housing 11. Similarly, the thermal conductivity of the cooling component 14 can be greater than that of the first housing 11, meaning the thermal conductivity of the cooling component 14 is greater than that of the first housing 11. The thermal conductivity of the second housing 12 and the cooling component 14 can be the same or different, and this is not limited here. In this embodiment, the thermal conductivity of the second housing 12 and the cooling component 14 are the same.

[0031] Multiple cooling conductors 14 are in direct contact with the refrigerant. The thermal conductivity of the second shell 12 and the cooling conductors 14 forms a pathway for cold energy transfer, enabling the cold energy of the refrigerant to be quickly conducted to the external environment (cold storage stage) or to absorb heat from the outside (cold release stage). This can significantly shorten the cold storage time and extend the effective cold release cycle.

[0032] Through the combined action of the first shell 11, the second shell 12, and the multiple heat-conducting components 14, when a partial air layer exists in the accommodating space 13 of the cold storage block 10, the heat-conducting components 14 directly contact the cold storage agent and form a heat exchange interface. Since the thermal conductivity of the second shell 12 and the multiple heat-conducting components 14 is greater than that of the first shell 11, the cold energy of the cold storage agent is transferred to the external environment through the heat-conducting components 14 and the second shell 12. The second shell 12 and the multiple heat-conducting components 14 enhance the efficiency of cold energy transfer between the cold storage agent and the external environment, thereby improving the cold retention effect of the cold storage block 10 and reducing the obstruction of cold energy transfer efficiency by the thin air layer.

[0033] Please see Figure 4 , Figure 4 This is a structural schematic diagram of the second shell and multiple heat-conducting components in the cold storage block of this application. (Combined with...) Figures 1 to 3 The aforementioned cooling conductor 14 can be configured in various ways, as long as it can transfer the cold energy in the refrigerant to the second housing 12. In some embodiments, the cooling conductor 14 extends along the first direction X and is connected to the second housing 12. Multiple cooling conductors 14 are arranged in a sequential array along the second direction Y. The second direction Y is different from the first direction X.

[0034] The first direction X can be, but is not limited to, the length direction of the cooling conductor 14. That is, the cooling conductor 14 extends along its own length direction and is connected to the second housing 12. As in this embodiment, a plurality of cooling conductors 14 are integrally formed along their length direction on one end face of the second housing 12 facing the receiving space 13.

[0035] Multiple cooling elements 14 are arranged in a sequential array along the second direction Y on the second housing 12. The second direction Y may be perpendicular to or not perpendicular to the first direction X. In this embodiment, the second direction Y is perpendicular to the first direction X.

[0036] By defining the extension direction and arrangement direction of multiple cooling conductive parts 14, it is possible not only to increase the area of ​​the heat exchange interface between the multiple cooling conductive parts 14 and the cold storage agent, thereby improving the efficiency of cold transfer, but also to facilitate demolding and improve manufacturability.

[0037] In one specific embodiment, when multiple cooling conductive elements 14 are arranged in a sequential array along the second direction Y in the second housing 12, the vertical spacing between adjacent cooling conductive elements 14 along the second direction Y can be the same or different. As in this embodiment, the vertical spacing between adjacent cooling conductive elements 14 along the second direction Y is the same, which can improve the uniformity of cold energy transfer efficiency.

[0038] In some embodiments, the first housing 11 is a plastic housing (not shown in the figure). The second housing 12 is a metal housing (not shown in the figure) or an alloy housing (not shown in the figure). And / or, the cooling element 14 is a metal cooling element (not shown in the figure) or an alloy cooling element (not shown in the figure).

[0039] The plastic casing is made of plastic. The metal casing is made of metal; or, the alloy casing is made of alloy. The metal cooling components are made of metal; or, the alloy cooling components are made of alloy.

[0040] The aforementioned metal materials can be, but are not limited to, aluminum, copper, and iron. Alloy materials can be, but are not limited to, aluminum alloys and stainless steel. The second housing 12 is a metal housing, and the cooling component 14 is a metal cooling component; the materials of the metal housing and the metal cooling component can be the same or different. Alternatively, the second housing 12 can be an alloy housing, and the cooling component 14 can be a metal cooling component. The thermal conductivity of the second housing 12, the cooling component 14, and the first housing 11 can be limited according to actual conditions and are not limited here. For example, in this embodiment, the first housing 11 is made of plastic; the second housing 12 and the cooling component 14 are both made of aluminum.

[0041] By defining the materials of the first housing 11 and the second housing 12, the efficiency of cold transfer between the refrigerant and the external environment is enhanced, thereby improving the cold retention effect of the cold storage block 10; moreover, it is easy to produce and obtain, and the cost is relatively low. And / or, by defining the material of the cold-conducting component 14, it is more conducive to the transfer of cold energy from the cold-conducting component 14 to the second housing 12.

[0042] In some embodiments, the second housing 12 insert is injection molded onto the first housing 11.

[0043] The second shell 12 and the first shell 11 are fitted together using an insert injection molding process to form the main structure of the cold storage block 10, so that the second shell 12 and the first shell 11 are integrally formed. This not only preserves the structural strength and sealing of the first shell 11, but also enhances the thermal conductivity through the second shell 12 and the cold conductive component 14.

[0044] When the first housing 11 is a plastic housing, the second housing 12 is a metal housing or an alloy housing, and the cooling component 14 is a metal cooling component or an alloy cooling component, not only is the structural strength and sealing performance of the plastic housing retained, but the thermal conductivity can also be enhanced through the second housing 12 and the cooling component 14.

[0045] Please see Figure 5 , Figure 6 , Figure 7 as well as Figure 8 , Figure 5 This is a schematic diagram of the outer shell of the cold storage block in this application; Figure 6 yes Figure 5 An enlarged schematic diagram of D is shown below; Figure 7 yes Figure 3 An enlarged schematic diagram of A shown; Figure 8 yes Figure 4 An enlarged schematic diagram of C is shown. (Combined with...) Figures 1 to 4 In some embodiments, the first housing 11 has two first connecting portions 1112 disposed opposite each other along the second direction Y. The first connecting portions 1112 are provided with insertion slots 11121. The second housing 12 has two insertion portions 121 disposed opposite each other along the second direction Y. The insertion portions 121 are inserted into the insertion slots 11121.

[0046] In this embodiment, the first housing 11 has a first connecting portion 1112 disposed on its inner sidewall relative to the second direction Y. The first connecting portion 1112 is detachably or fixedly connected to the inner sidewall of the first housing 11. In this embodiment, the first connecting portion 1112 is integrally formed on the inner sidewall of the first housing 11. The insertion groove 11121 provides installation space for the insertion portion 121. The shape of the insertion groove 11121 matches the shape of the insertion portion 121.

[0047] The second housing 12 is provided with insertion portions 121 at both opposite ends along the second direction Y. The insertion portions 121 are detachably or fixedly connected to the inner sidewall of the second housing 12. In this embodiment, the insertion portions 121 are integrally formed into the inner sidewall of the second housing 12. The insertion portions 121 are inserted into the corresponding insertion slots 11121.

[0048] Through the combined action of the two first connecting portions 1112 of the first housing 11 and the two plug-in portions 121 of the second housing 12, the second housing 12 can be inserted into the first housing 11, thereby improving the stability of the second housing 12 installed in the first housing 11.

[0049] In some embodiments, one of the sides of the insertion portion 121 facing the insertion groove 11121 and the other of the sides of the insertion groove 11121 facing the insertion portion 121 is provided with a first protrusion 11121a, and the other of the two is provided with a first recess 1211. The first protrusion 11121a is defined within the first recess 1211.

[0050] The first protrusion 11121a and the first recess 1211 have at least two different configuration positions. In this embodiment, the first recess 1211 is provided on the side of the insertion portion 121 facing the insertion groove 11121. The first protrusion 11121a is provided on the side of the insertion groove 11121 facing the insertion portion 121. The first protrusion 11121a is detachably or fixedly connected to the insertion groove 11121. In another specific embodiment, the first protrusion 11121a is provided on the side of the insertion portion 121 facing the insertion groove 11121. The first protrusion 11121a is detachably or fixedly connected to the insertion portion 121. The first recess 1211 is provided on the side of the insertion groove 11121 facing the insertion portion 121.

[0051] Assuming a cold storage block 10 is placed horizontally, a first protrusion 11121a is provided on the upper and / or lower surfaces of the insertion portion 121, and a first recess 1211 is provided on the upper and / or lower sidewalls of the insertion groove 11121. The first protrusion 11121a is confined within the corresponding first recess 1211. The number of the first protrusions 11121a and the number of the first recesses 1211 can be, but are not limited to, one, two, or more than three.

[0052] The insertion portion 121 and the insertion groove 11121 are further defined by the first protrusion 11121a and the first recess 1211, which can reduce the risk of the second housing 12 becoming detached from the first housing 11, thereby improving the stability of the second housing 12 installed on the first housing 11.

[0053] In one specific embodiment, both the first protrusion 11121a and the first recess 1211 extend along the first direction X. The second direction Y is different from the first direction X.

[0054] The first protrusion 11121a and the first recess 1211 extend in the same direction as the length of the cooling conductor 14. When the cooling conductor 14 is subjected to force, the first protrusion 11121a and the first recess 1211, which extend along the first direction X, not only increase the contact area between the insertion part 121 and the insertion groove 11121, further reducing the risk of the second housing 12 becoming detached from the first housing 11, but also increase the resistance to the second housing 12 becoming detached from the first housing 11. When there are multiple first protrusions 11121a and multiple first recesses 1211, the multiple first protrusions 11121a and multiple first recesses 1211 are arranged in a sequential array along the second direction Y. Adjacent first protrusions 11121a are spaced at equal or unequal intervals.

[0055] In some embodiments, the first housing 11 is provided with two second connecting portions 1113 opposite each other along the first direction X. The second connecting portions 1113 are provided with a plurality of snap-fit ​​grooves 11131. The end of the cooling guide 14 is snapped into the snap-fit ​​groove 11131.

[0056] In this embodiment, the first housing 11 has a second connecting portion 1113 disposed on its inner sidewall relative to the first direction X. The second connecting portion 1113 is detachably or fixedly connected to the inner sidewall of the first housing 11. In this embodiment, the second connecting portion 1113 is integrally formed on the inner sidewall of the first housing 11. The snap-fit ​​groove 11131 provides an installation position for the cooling conductive component 14. The shape and number of the snap-fit ​​groove 11131 can correspond to the shape and number of the cooling conductive component 14, and are not limited here. The ends of the multiple cooling conductive components 14 are snapped into the corresponding snap-fit ​​groove 11131.

[0057] Through the combined action of the two second connecting parts 1113 of the first housing 11 and the snap-fit ​​groove 11131 of the second housing 12, not only is a certain supporting force provided for the cooling component 14, thereby improving the stability of the installation of the cooling component 14, but also the stability of the cold energy transmission is provided.

[0058] Please see Figure 9 and Figure 10 , Figure 9 This is a second cross-sectional schematic diagram of an embodiment of the cold storage block of this application; Figure 10 yes Figure 9 An enlarged schematic diagram of E is shown. (Combined with...) Figures 1 to 8 In some embodiments, one of the sides of the second connecting portion 1113 facing the second housing 12 and the other of the sides of the second housing 12 facing the second connecting portion 1113 are provided with a second protrusion 11132, and the other is provided with a second recess 122. The second protrusion 11132 is confined within the second recess 122.

[0059] The second protrusion 11132 and the second recess 122 have at least two possible positions. For example, in this embodiment... Figure 8 As shown, a second protrusion 11132 is provided on the side of the second connecting portion 1113 facing the second housing 12. The second protrusion 11132 is detachably or fixedly connected to the second connecting portion 1113. A second recess 122 is provided on the side of the second housing 12 facing the second connecting portion 1113. In another specific embodiment, a second recess 122 is provided on the side of the second connecting portion 1113 facing the second housing 12. A second protrusion 11132 is provided on the side of the second housing 12 facing the second connecting portion 1113. The second protrusion 11132 is detachably or fixedly connected to the second housing 12. The number of the above-mentioned second protrusions 11132 and the number of the second recesses 122 may be, but are not limited to, one, two, or three or more.

[0060] The second connecting part 1113 and the second housing 12 are further defined by the second protrusion 11132 and the second recess 122, which not only increases the contact area between the second connecting part 1113 and the second housing 12, thereby increasing the cooling area and the support area, but also improves the sealing performance of the cold storage block 10 and facilitates demolding.

[0061] In one specific embodiment, both the second protrusion 11132 and the second recess 122 extend along the first direction X. The second direction Y is different from the first direction X.

[0062] The extension directions of the second protrusion 11132 and the second recess 122 can be the same as the extension directions of the first protrusion 11121a and the first recess 1211. When the cooling component 14 is subjected to force, the second protrusion 11132 and the second recess 122, which extend along the first direction X, not only increase the contact area between the second connecting portion 1113 and the second housing 12, further reducing the risk of the second housing 12 becoming detached from the first housing 11, but also increase the resistance to the second housing 12 becoming detached from the first housing 11. When there are multiple second protrusions 11132 and second recesses 122, the multiple second protrusions 11132 and the multiple second recesses 122 are arranged in a sequential array along the second direction Y. Adjacent second protrusions 11132 are spaced at equal or unequal intervals.

[0063] In some embodiments, the depth of the second recess 122 along a third direction is greater than or equal to 0.2 mm and less than or equal to 0.4 mm. The third direction is different from the first direction X. And / or, the width of the second recess 122 along a second direction Y is greater than or equal to 0.5 mm and less than or equal to 1.5 mm. The second direction Y is different from the first direction X.

[0064] The depth of the second recess 122 along the third direction can be, but is not limited to, 0.20 mm, 0.24 mm, 0.28 mm, 0.3 mm, 0.35 mm, 0.38 mm, and 0.4 mm. When the cold storage block 10 is placed horizontally, the third direction can be vertical.

[0065] And / or, the width of the second recess 122 along the second direction Y may be, but is not limited to, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, and 1.5 mm.

[0066] By limiting the depth range of the second recess 122 along the third direction, not only can the cooling area and support area be increased, but demolding can also be facilitated. And / or, by limiting the width of the second recess 122 along the second direction Y, not only can the cooling area and support area be increased, but demolding can also be facilitated.

[0067] In some embodiments, at least one of the two sides of the cooling conductor 14 is provided with a third recess (not shown in the figure). By providing the aforementioned third recess on the side of the cooling conductor 14, the contact area between the cooling conductor 14 and the refrigerant can be increased, allowing more cooling energy to be transferred to the external environment through the cooling conductor 14 and the second housing 12, thereby further improving the cooling energy transfer efficiency.

[0068] As described above, the depth range of the first recess 1211 and the depth range of the third recess can be the same as or similar to the depth range of the second recess 122. The width range of the first recess 1211 and the width range of the third recess can be the same as or similar to the width range of the second recess 122.

[0069] Please continue reading. Figures 1 to 10 In some embodiments, the first housing 11 includes an outer shell 111 and a first cover plate 112. The outer shell 111 is provided with a second mounting opening 1114. The second mounting opening 1114 and the first mounting opening 1111 are disposed opposite to each other. The second housing 12 includes a second cover plate (not shown in the figure). The first cover plate 112 and the second cover plate are disposed opposite to each other. The first cover plate 112 is connected to the outer shell 111 and covers the second mounting opening 1114.

[0070] The second mounting port 1114 and the first mounting port 1111 are arranged opposite to each other. The second mounting port 1114 provides a mounting position for the first cover plate 112. The first mounting port 1111 provides a mounting position for the second cover plate. The first cover plate 112 and the second cover plate are plate-shaped; the outer shell 111 is annular.

[0071] The first cover plate 112 is detachably or fixedly connected to the outer casing 111. Detachment can be achieved through, but is not limited to, snap-fit ​​and plug-in connections. Fixing can be achieved through, but is not limited to, welding and bonding. In this embodiment, the first cover plate 112 is ultrasonically welded to the second mounting port 1114 of the outer casing 111. When the first cover plate 112 is connected to the outer casing 111, it covers the second mounting port 1114.

[0072] The combined action of the outer shell 111, the first cover plate 112, and the second cover plate facilitates the implementation of insert injection molding between the first shell 11 and the second shell 12, thereby reducing structural interference.

[0073] Both the outer shell 111 and the first cover plate 112 can be made of plastic. The material of the outer shell 111 can be the same as or different from that of the first cover plate 112, which is not limited here.

[0074] Please see Figure 11 , Figure 11 yes Figure 3 An enlarged schematic diagram of B is shown. (Combined with...) Figures 1 to 10 In one specific embodiment, a stepped portion 1117 is provided at one end of the outer casing 111 near the second mounting port 1114. A stepped groove 1122 is provided on one end face of the first cover plate 112 facing the outer casing 111. The stepped portion 1117 and the stepped groove 1122 are stepped and their shapes match each other, which not only allows the first cover plate 112 to fit onto the end of the outer casing 111 near the second mounting port 1114, but also increases the ultrasonic welding area, thereby improving the stability of the first cover plate 112 installed on the outer casing 111. During the installation of the first cover plate 112 on the outer casing 111, the end face of the first cover plate 112 facing away from the receiving space 13 is flush with the end face of the outer casing 111 near the second mounting port 1114.

[0075] Please see Figure 12 , Figure 12 This is a structural schematic diagram of the first cover plate in the cold storage block of this application. Combined with... Figures 1 to 11 In some embodiments, the cold storage block 10 includes a seal 15. A first housing 11 is provided with a liquid injection hole 1121. The liquid injection hole 1121 communicates with the receiving space 13. The seal 15 is connected to the liquid injection hole 1121. The liquid injection hole 1121 and the second housing 12 are disposed opposite each other.

[0076] The injection hole 1121 serves as the inlet for the refrigerant to enter the containment space 13. The injection hole 1121 is located at one end of the first housing 11 facing the second housing 12. For example, the injection hole 1121 can be located on the first cover plate 112 of the first housing 11. The refrigerant enters the containment space 13 through the injection hole 1121.

[0077] The seal 15 has a sealing function. The seal 15 may be, but is not limited to, a sealing plug. The seal 15 is sealed within the injection port 1121. The sealing plug may be interference-fitted into the injection port 1121.

[0078] By connecting the sealing element 15 to the injection hole 1121, the risk of refrigerant leakage can be reduced, thereby improving the long-term sealing reliability after refrigerant filling and significantly enhancing the practical value of the refrigerant block 10. In addition, by limiting the location of the injection hole 1121 in the first housing 11, it is not only convenient for the user to add refrigerant to the refrigerant block 10, but also reduces the interference effect of assembling multiple refrigerant blocks 10.

[0079] The number of injection holes 1121 can be one, two, or more than three. When there is only one injection hole 1121, the multiple cooling elements 14 are spaced apart from the end of the second housing 12 and the first cover plate 112, allowing the refrigerant to flow between the receiving space 13 and adjacent cooling elements 14. The injection hole 1121 can be located at any position on the first cover plate 112. In this embodiment, the injection hole 1121 is located at the middle position of the first cover plate 112.

[0080] When there are multiple injection holes 1121, the ends of multiple cooling conductive elements 14 away from the second housing 12 and the first cover plate 112 can be spaced apart; or, the ends of multiple cooling conductive elements 14 away from the second housing 12 and the first cover plate 112 are connected. In this case, the adjacent cooling conductive elements 14 divide the accommodating space 13 into mutually independent sub-accommodating spaces (not shown in the figure), and each sub-accommodating space is connected to at least one injection hole 1121.

[0081] In some embodiments, the ratio of the amount of refrigerant to the volume of the accommodating space 13 is greater than or equal to 0.8 and less than or equal to 0.95.

[0082] The ratio of the amount of refrigerant to the volume of the containing space 13 can be, but is not limited to, 0.80, 0.82, 0.83, 0.85, 0.86, 0.87, 0.88, 0.90, 0.91, 0.92, 0.93, and 0.95. In this embodiment, the ratio of the amount of refrigerant to the volume of the containing space 13 is 0.9, meaning the amount of refrigerant is 90% of the volume of the containing space 13.

[0083] By limiting the range of the ratio of the amount of refrigerant to the volume of the storage space 13, not only can the cold storage capacity of the cold storage block 10 be increased, but the safety of using the cold storage block 10 can also be improved.

[0084] In some embodiments, the first protrusion 11121a, the first recess 1211, the second protrusion 11132, the second recess 122, and the cooling member 14 extend in the same direction.

[0085] Please see Figure 13 and Figure 14 , Figure 13 This is a schematic diagram of a planar structure of one embodiment of the cold storage structure of this application; Figure 14 This is a three-dimensional structural diagram of an embodiment of the cold storage structure of this application. (Combined with...) Figures 1 to 12 This application provides a cold storage structure. The cold storage structure 100 includes a plurality of cold storage blocks 10. The plurality of cold storage blocks 10 can be assembled to form a planar or three-dimensional shape.

[0086] It should be noted that the cold storage block 10 in this embodiment is the same as the cold storage block 10 described in the above embodiments, and will not be repeated here. The number of cold storage blocks 10 can be, but is not limited to, two, three, or more than four. Multiple cold storage blocks 10 can be spliced ​​to form a planar cold storage structure 100 to adapt to large-area cold preservation requirements; wherein, the second shell 12 in the cold storage structure 100 is in contact with the component to be cooled. Alternatively, multiple cold storage blocks 10 can be spliced ​​to form a three-dimensional cold storage structure 100 to adapt to spatial layout; wherein, the second shell 12 in the cold storage structure 100 is in contact with the component to be cooled.

[0087] Multiple cold storage blocks 10 can be freely assembled to form cold storage structures 100 of different shapes. This not only allows them to be flexibly combined to form large planar or three-dimensional shapes according to the needs of actual application scenarios, thus solving the problem that the application range is limited due to the fixed shape of some existing cold storage blocks 10, thereby improving the adaptability to diverse space and area requirements; it also improves the cold storage and insulation efficiency. For example, the free combination and assembly of multiple cold storage blocks 10 can flexibly adapt to the customized needs of diverse scenarios such as outdoor camping and medical insulation, expanding the application range to multi-dimensional spatial scenarios that traditional products cannot cover.

[0088] In some embodiments, the cold storage block 10 is square or rectangular. By limiting the cold storage block 10 to a square or rectangular shape, not only is the assembly of the cold storage structure 100 simplified, but the adaptability to diverse space and area requirements is also further improved.

[0089] Please see Figure 15 , Figure 15 This is a second structural schematic diagram of an embodiment of the cold storage block of this application. (Combined with...) Figures 1 to 14 In some embodiments, male connectors 1115 are provided on the surfaces of two adjacent sidewalls of the cold storage block 10. Female connectors 1116 are provided on the surfaces of the other two adjacent sidewalls of the cold storage block 10. Adjacent cold storage blocks 10 are connected by interference fit between the male connectors 1115 and the female connectors 1116.

[0090] When the cold storage block 10 is square or rectangular, it includes a first sidewall 10a, a second sidewall 10b, a third sidewall 10c, and a fourth sidewall 10d. The first sidewall 10a and the second sidewall 10b are arranged opposite to each other. The third sidewall 10c and the fourth sidewall 10d are arranged opposite to each other. The first sidewall 10a and the fourth sidewall 10d are arranged adjacent to each other. The second sidewall 10b and the third sidewall 10c are arranged adjacent to each other.

[0091] Assume that the first sidewall 10a and the fourth sidewall 10d of a cold storage block 10 are provided with female connectors 1116; the second sidewall 10b and the third sidewall 10c of a cold storage block 10 are provided with male connectors 1115. During the splicing of multiple cold storage blocks 10, the female connector 1116 of a cold storage block 10 and the male connector 1115 of the adjacent cold storage block 10 are interference-fitted; the male connector 1115 of a cold storage block 10 and the female connector 1116 of the adjacent cold storage block 10 are interference-fitted.

[0092] By defining the male portion 1115 on the two adjacent sidewall surfaces of the cold storage block 10 and the female portion 1116 on the other two adjacent sidewall surfaces of the cold storage block 10, during the splicing of multiple cold storage blocks 10, not only can any number of cold storage blocks 10 be freely assembled and disassembled, but the gap between adjacent cold storage blocks 10 can also be reduced, thereby improving the uniformity of cold storage efficiency.

[0093] In one specific embodiment, the male connector 1115 includes a male surface 11151 and two male side surfaces 11152. One male side surface 11152 is perpendicularly connected to one end of the male surface 11151, and the other male side surface 11152 is perpendicularly connected to the other end of the male surface 11151. The end face of the male surface 11151 facing away from the male side surface 11152, the end face of the first housing 11 near the first mounting port 1111, and the end face of the second housing 12 facing away from the receiving space 13 are flush with each other.

[0094] The female connector 1116 includes two female connectors 1116 and a female groove formed by the two female connectors 1116. One male side 11152 abuts against one side wall of the female groove, and the other male side 11152 abuts against the other side wall of the female groove. The female connector 1116 includes a female surface 11161 and two female sides 11162. One female side 11162 is perpendicularly connected to one end of the female surface 11161; the other female side 11162 is perpendicularly connected to the other end of the female surface 11161. The end face of the female surface 11161 facing away from the female side 11162, the end face of the first housing 11 near the first mounting port 1111, and the end face of the second housing 12 facing away from the receiving space 13 are flush with each other.

[0095] By defining the specific structure of the male connector 1115 and the female connector 1116, the assembly between adjacent cold storage blocks 10 is made more complete, thereby reducing the gap between adjacent cold storage blocks 10 and improving the uniformity of cold storage efficiency.
