Description

[0001] The present invention relates to the field of refrigeration technology, and in particular to a cold storage device and refrigeration equipment. Background Art

[0002] Existing cold storage plates are directly filled with coolant so that the coolant is in direct contact with the metal plate. This increases the heat transfer area and facilitates rapid heat exchange. However, most coolants can corrode the metal plate, causing it to leak.

[0003] In the related art, the cold storage plate adopts a bagged cold storage method, and the bagged cold storage agent is pre-packaged for protection. However, the volume of the bagged cold storage agent will change during the phase change process, resulting in the cold storage package as a whole presenting a larger arc surface after the phase change, which reduces the contact area between the bagged cold storage agent and the metal plate, thereby reducing the heat exchange area. Therefore, the heat exchange continuity and heat exchange speed become worse, resulting in worse heat exchange effect. Summary of the Invention

[0044] See also Figures 1 to 5An embodiment of the present invention provides a cold storage device 100. Cold storage device 100 includes a cold storage element 10, a force-applying assembly 30, a heat-conducting element 50, and at least one cold storage pack 70. A working chamber 12 is formed within the cold storage element 10, and the heat-conducting element 50 is connected to the cold storage element 10. At least one cold storage pack 70 is located in the working chamber 12 and is used to store cold energy. The force-applying assembly 30 is configured to apply force to the cold storage pack 70 and / or the heat-conducting element 50 to maintain contact between the cold storage pack 70 and the heat-conducting element 50.

[0045] In the above-mentioned cold storage device 100, the force-applying component 30 is configured to apply force to the cold storage pack 70 so that the cold storage pack 70 and the heat conductor 50 maintain abutment, thereby improving the fit between the cold storage pack 70 and the heat conductor 50 during the cold storage phase change process and the cold release process, ensuring the contact area between the cold storage pack 70 and the heat conductor 50, thereby ensuring the heat exchange speed and heat exchange continuity of the cold storage device 100.

[0046] Specifically, in one embodiment, the cold storage component 10 can be a component of the outer shell of the cold storage device 100 and can be used to provide a closed environment to reduce the cold loss rate of the cold storage package 70 while ensuring the safe placement of the cold storage package 70.

[0047] In one example, the cold storage component 10 can be made of thermal insulation material to reduce the loss of cold energy in the cold storage pack 70 and ensure that the cold storage pack 70 efficiently transfers heat through the heat conductive component 50, thereby improving the cold energy utilization efficiency of the cold storage pack 70.

[0048] In one embodiment, a working chamber 12 is formed within the cooling element 10 to ensure that at least one cooling pack 70 is stably placed within the working chamber 12. The volume of the working chamber 12 is adjustable, that is, the volume of the working chamber 12 can change with the phase change of the cooling agent within the cooling pack 70, thereby providing a space of appropriate volume to ensure that the cooling pack 70 and the thermal conductive element 50 maintain contact.

[0049] In one embodiment, the force-applying component 30 can form an interaction force so that the cold storage pack 70 and the heat conductive member 50 are in close contact with each other and maintain an abutment state. While ensuring the contact area, the cold storage pack 70 and the objects placed on the heat conductive member 50 can continuously exchange heat, thereby improving the heat exchange efficiency.

[0050] In some examples, the force applying component 30 may be a spring, a magnet, or other material that can provide deformation tension to ensure that the cold storage pack 70 and the heat conducting member 50 maintain contact, which is not specifically limited here.

[0051] That is, the interaction force may be elastic force, magnetic force, or other forms of force, so that the cold storage pack 70 and the heat conductor 50 maintain contact for efficient heat transfer, and no specific limitation is made here.

[0052] In one embodiment, at least a portion of the heat conductor 50 can be clamped and fixed in the cold storage component 10 to connect the heat conductor 50 to the cold storage component 10. The heat conductor 50 and the cold storage component 10 can also be fixed by screws or the like, thereby further improving the stability of the heat conductor 50.

[0053] In one embodiment, the heat conductor 50 can be a tray for placing objects, which can not only carry the objects placed, but also increase the heat conduction speed of the objects placed, thereby improving the heat exchange efficiency between the objects placed and the cold storage bag 70, and further ensuring the cold utilization efficiency of the cold storage bag 70.

[0054] Optionally, the heat conductor 50 can be a metal member or a non-metal member to ensure efficient heat exchange between the object and the cold storage pack 70. For example, the heat conductor 50 can be a metal or alloy member such as aluminum, copper, iron, or nickel, or a non-metal member such as silicone, graphite, or thermally conductive ceramic, without specific limitation herein.

[0055] In one embodiment, the coolant pack 70 contains a coolant with a stable phase transition temperature point, which can be used to provide a safe heat exchange environment for the coolant, avoiding risks such as corrosion and leakage. The coolant is initially in a liquid state, and its temperature can be adjusted, for example, by releasing cold energy through a heat exchanger (not shown) to allow the coolant to absorb sufficient cold energy. For example, when the coolant changes from a liquid state to a solid state or a solid-liquid two-phase state at a sufficiently low temperature, a target object is placed on the heat conductive element 50, causing the coolant pack 70 to begin operating and exchanging heat with the target object, thereby ensuring that the coolant pack 70 continuously provides cold energy to the heat conductive element 50.

[0056] It can be understood that when the coolant is in liquid state, the force-applying component 30 can use the interaction force to make the coolant bag 70 and the heat conductor 50 tightly arranged. When the coolant changes from "liquid-solid-liquid" in sequence, the volume of the coolant bag 70 changes from "small-large-small" in sequence. By maintaining the coolant bag 70 and the heat conductor 50 in contact when the volume of the coolant bag 70 is minimum, the tension can be used to ensure that the coolant bag 70 and the heat conductor 50 maintain contact before and after the phase change of the coolant.

[0057] For example, in one embodiment, when the force-applying assembly 30 applies a compressive elastic force to the end of the coolant pack 70 away from the thermal conductor 50, the coolant pack 70, which contains liquid coolant, abuts the thermal conductor 50. When the liquid coolant changes to solid coolant, the coolant pack 70 expands, causing the compressive elastic force to continue to increase, causing the coolant pack 70 to continue to move toward the thermal conductor 50, thereby ensuring that the coolant pack 70 maintains abutment with the thermal conductor 50, thereby achieving the purpose of maintaining abutment between the coolant pack 70 and the thermal conductor 50 before and after the coolant phase change.

[0058] In one embodiment, the heat conductor 50 is fixedly arranged. It can be understood that the force-applying component 30 can apply force to the heat conductor 50 while applying force to the side of the cold storage bag 70 away from the heat conductor 50, so that the cold storage bag 70 and the heat conductor 50 are relatively close, thereby maintaining the cold storage bag 70 and the heat conductor 50 in contact, thereby avoiding the cold storage bag 70 collapsing due to phase change during use, resulting in an increase in the air thermal resistance between the cold storage bag 70 and the heat conductor 50, resulting in insufficient cooling supply to the heat conductor 50.

[0059] In another embodiment, the heat conductive member 50 is fixedly arranged. It can be understood that the force-applying component 30 can also apply force only to the side of the cold storage bag 70 away from the heat conductive member 50, so that the cold storage bag 70 moves toward the direction close to the heat conductive member 50, thereby maintaining the cold storage bag 70 in contact with the heat conductive member 50.

[0060] In other embodiments, the force-applying component 30 may also maintain the contact between the cold storage pack 70 and the heat conductive member 50 in other ways. Of course, the heat conductive member 50 may also be movable, which is not specifically limited here.

[0061] See also Figures 1 to 3 In some embodiments, the force-applying assembly 30 includes an elastic member 32 and a pressure plate 34. The elastic member 32 is connected to the pressure plate 34. The elastic member 32 is used to provide elastic force to the pressure plate 34 so that the pressure plate 34 applies force to the cold storage pack 70 and / or the heat conductive member 50 so that the cold storage pack 70 and the heat conductive member 50 maintain abutment.

[0062] In this way, an elastic force is generated to keep the cold storage pack 70 and the heat conducting member 50 in contact with each other, thereby ensuring the heat exchange efficiency of the cold storage device 100 .

[0063] Specifically, in one embodiment, the elastic member 32 may be a spring or other deformable object to ensure that the cold storage pack 70 is in contact with the heat conducting member 50 , which is not specifically limited herein.

[0064] In one embodiment, the pressure plate 34 is disposed below the cold storage pack 70 to support the cold storage pack 70 to ensure safe operation of the cold storage pack 70 .

[0065] For example, in some examples, the pressure plate 34 can be made of metal materials such as iron and aluminum, or non-metallic materials such as carbon fiber and polyimide to provide greater pressure-bearing strength to ensure that the cold storage bag 70 is stably placed. No specific restrictions are made here.

[0066] In one embodiment, the pressure plate 34 is movable and the heat conductor 50 is fixed, for example, the heat conductor 50 is fixed by screws. The pressure plate 34 can press the cold storage pack 70 against the heat conductor 50 through the elastic force provided by the elastic member 32, thereby ensuring that the cold storage pack 70 and the heat conductor 50 maintain contact.

[0067] It can be understood that the elastic member 32 can provide a pulling force or a pushing force so that the cold storage pack 70 and the heat conductive member 50 maintain contact, and no specific limitation is made here.

[0068] In one embodiment, the elastic member 32 provides a tensile force, that is, the elastic member 32 can be arranged between the pressure plate 34 and the heat conductive member 50, so that the pressure plate 34 is subjected to the tensile force to move closer to the cold storage bag 70 located in the working chamber 12, thereby ensuring that the pressure plate 34 and the heat conductive member 50 maintain abutment.

[0069] In another embodiment, the elastic member 32 provides thrust, that is, the elastic member 32 can also be arranged on the side of the pressure plate 34 away from the heat conductor 50, so that the pressure plate 34 is acted upon by the thrust to push the cold storage bag 70 toward the heat conductor 50, thereby ensuring that the pressure plate 34 and the heat conductor 50 maintain abutment.

[0070] In one embodiment, the pressure plate 34 may be provided with grooves, holes or fixings, etc., so that the elastic member 32 is connected to the pressure plate 34, thereby ensuring that the pressure plate 34 stably transmits the force, thereby ensuring that the cold storage pack 70 and the heat conductive member 50 maintain contact, and no specific restrictions are made here.

[0071] See also Figure 1 In some embodiments, the cold storage component 10 includes a base plate 14, a pressure plate 34 is arranged on the top of the force-applying component 30, the base plate 14 is arranged opposite to the pressure plate 34 and is located at the bottom of the force-applying component 30, the pressure plate 34 and the base plate 14 define a movement space, the elastic member 32 passes through the movement space and compressively connects the pressure plate 34 and the base plate 14, so that the pressure plate 34 can movably support at least one cold storage pack 70.

[0072] In this way, the elastic member 32 provides a thrust to the pressure plate 34 , thereby ensuring that the cold storage pack 70 and the heat conducting member 50 maintain contact, thereby improving the heat exchange efficiency of the cold storage device 100 .

[0073] Specifically, in one embodiment, the bottom plate 14 is disposed at the bottom of the cold storage component 10 , and can provide support and sealing conditions for the cold storage device 100 , thereby ensuring safe operation of the cold storage device 100 .

[0074] In one embodiment, a movement space is defined between the pressure plate 34 and the bottom plate 14 so that the elastic member 32 can be compressed and changed movably within the movement space, thereby ensuring the movement space required for the coolant in the cool storage pack 70 to produce a phase change, preventing the cool storage pack 70 from being squeezed and damaged, and thereby improving the safety of the cool storage device 100.

[0075] It can be understood that the movement space can ensure that the pressure plate 34 can movably support the cold storage pack 70, so that the cold storage pack 70 is pressed against the heat conductor 50 and maintains contact, which is practical.

[0076] In one embodiment, when the coolant in the cool storage pack 70 is in an initial state (for example, the initial state is liquid), the elastic member 32 passes through the movement space and compressively connects the pressure plate 34 and the bottom plate 14 to support the cool storage pack 70 through the compressive elastic force, so that the cool storage pack 70 abuts against the heat conductive member 50.

[0077] Furthermore, when the coolant in the cool storage bag 70 absorbs cold energy and undergoes a phase change, for example, when the coolant changes from liquid to solid, the cool storage bag 70 changes from a collapsed state to a bulging state, and its volume increases. Force can be applied to both sides of the pressure plate 34 and the heat conductor 50, causing the pressure plate 34 to move away from the heat conductor 50, thereby further compressing the elastic member 32, that is, the compressive elastic force is further increased, thereby ensuring that the cool storage bag 70 and the heat conductor 50 maintain contact.

[0078] In summary, the elastic member 32 can be arranged in the movement space, wherein the movement space and the working chamber 12 are separated by the pressure plate 34 to form a thrust to push the pressure plate 34 to move in the direction of the heat conductor 50, thereby ensuring that the cold storage bag 70 and the heat conductor 50 maintain contact, thereby ensuring the heat exchange efficiency of the cold storage device 100.

[0079] In some embodiments, a first limiting groove 341 is provided on the side of the pressure plate 34 close to the base plate 14, and a second limiting groove 141 is provided on the side of the base plate 14 close to the pressure plate 34. The first limiting groove 341 and the second limiting groove 141 are arranged opposite to each other, and the first limiting groove 341 is connected to one end of the elastic member 32, and the second limiting groove 141 is connected to the other end of the elastic member 32.

[0080] In this way, the elastic member 32 stably connects the pressing plate 34 and the bottom plate 14 to ensure that the elastic member 32 provides a stable thrust to the pressing plate 34 , thereby ensuring that the cold storage pack 70 works safely.

[0081] Specifically, in one embodiment, the first limiting groove 341 may be cylindrical, so as to limit one end of the elastic member 32 in the cylindrical slot, so that the elastic member 32 has good stability and is not easy to fall off.

[0082] It is understandable that one side of the pressure plate 34 close to the bottom plate 14 can protrude to form a hollow cylinder to form a cylindrical first limiting groove 341, thereby ensuring that one end of the elastic member 32 is stably placed in the first limiting groove 341.

[0083] Similarly, the second limiting groove 141 can be cylindrical to limit the other end of the elastic member 32 in the cylindrical slot, so that the elastic member 32 has good stability and is not easy to fall off.

[0084] It is understandable that one side of the bottom plate 14 close to the pressing plate 34 may protrude to form a hollow cylinder to form a cylindrical second limiting groove 141 , thereby ensuring that the other end of the elastic member 32 is stably placed in the second limiting groove 141 .

[0085] In other embodiments, the first limiting groove 341 and the second limiting groove 141 may also be other shapes. Of course, the first limiting groove 341 and the second limiting groove 141 may be the same shape or different shapes. It only needs to ensure that the elastic member 32 is stably set, and no specific restrictions are made here.

[0086] In one embodiment, the first limiting groove 341 and the second limiting groove 141 are located in the movement space and are arranged relative to each other to ensure that the elastic member 32 is stably connected to the pressure plate 34 and the bottom plate 14, thereby ensuring that the elastic member 32 can be movably compressed and changed in the movement space, and then provide a stable thrust to the pressure plate 34 to ensure that the cold storage bag 70 and the heat conductive member 50 maintain abutment.

[0087] In one embodiment, the number of the first limiting groove 341 can be one or more, so as to stably support the cold storage pack 70 through at least one elastic member 32, and no specific limitation is made here.

[0088] Similarly, the number of the second limiting grooves 141 can be one or more, as long as the number of the first limiting grooves 341 and the second limiting grooves 141 are equal, which will not be repeated here.

[0089] In summary, the elastic member 32 is stably placed by the first limiting groove 341 and the second limiting groove 141 to ensure that the pressure plate 34 stably supports the cold storage pack 70, thereby improving the safety of the cold storage pack 70.

[0090] It is worth noting that the first limiting groove 341 and the second limiting groove 141 are arranged relative to each other and the elastic member 32 is stably placed to improve the horizontality of the pressure plate 34, thereby increasing the contact area between the cold storage package 70 and the heat conducting member 50 as much as possible to ensure heat exchange efficiency.

[0091] See also Figure 2 In some embodiments, the cold storage device 100 includes a cold storage member 10, a working chamber 12 is formed in the cold storage member 10, a pressure plate 34 is located at the bottom of the working chamber 12, a heat conductor 50 is located at the top of the working chamber 12, an elastic member 32 passes through the working chamber 12 and stretches to connect the heat conductor 50 and the pressure plate 34, the cold storage member 10 includes a bottom plate 14, the pressure plate 34 and the bottom plate 14 define a movement space, so that the pressure plate 34 can movably support at least one cold storage pack 70.

[0092] In this way, the elastic member 32 provides a pulling force to the pressure plate 34 , thereby ensuring that the cold storage pack 70 and the heat conducting member 50 maintain contact, thereby improving the heat exchange efficiency of the cold storage device 100 .

[0093] Specifically, in one embodiment, a working chamber 12 is defined between the heat conductor 50 and the pressure plate 34, so that the elastic member 32 can be stretched and changed movably in the working chamber 12, thereby ensuring the movable space required for the coolant in the cool storage pack 70 to produce a phase change, avoiding the cool storage pack 70 from being squeezed and damaged, and thereby improving the safety of the cool storage device 100.

[0094] It can be understood that the volume of the working chamber 12 is adjustable and can be reduced accordingly with the collapse of the cold storage pack 70 or increased accordingly with the bulging of the cold storage pack 70 to avoid the cold storage pack 70 being squeezed and damaged, thereby improving the safety of the cold storage device 100.

[0095] In one embodiment, when the coolant in the cool storage pack 70 is in an initial state (for example, the initial state is liquid), the elastic member 32 passes through the working chamber 12 and stretches to connect the heat conductor 50 and the pressure plate 34, so as to pull the pressure plate 34 by stretching the elastic force to support the cool storage pack 70, so that the cool storage pack 70 abuts against the heat conductor 50.

[0096] Furthermore, when the coolant in the cool storage bag 70 absorbs cold energy and undergoes a phase change, for example, when the coolant changes from liquid to solid, the cool storage bag 70 changes from a collapsed state to a bulging state, and its volume increases. Force can be applied to both sides of the pressure plate 34 and the heat conductor 50, causing the pressure plate 34 to move away from the heat conductor 50, thereby further stretching the elastic member 32, that is, the stretching elastic force is further increased, thereby ensuring that the cool storage bag 70 and the heat conductor 50 maintain contact.

[0097] In one embodiment, a movement space is defined between the pressure plate 34 and the bottom plate 14, that is, the working chamber 12 and the movement space are separated by the pressure plate 34. When the cold storage pack 70 changes from a collapsed shape to a bulged shape, the volume of the working chamber 12 increases, and the volume of the movement space decreases, thereby ensuring that the pressure plate 34 can be movably arranged inside the cold storage component 10.

[0098] In summary, the elastic member 32 can be arranged in the working chamber 12, wherein the working chamber 12 and the movement space are separated by the pressure plate 34 to form a pulling force to pull the pressure plate 34 and the heat conductive member 50 to clamp the stable cold storage bag 70, thereby ensuring that the cold storage bag 70 and the heat conductive member 50 maintain abutment, thereby ensuring the heat exchange efficiency of the cold storage device 100.

[0099] See also Figure 2 In some embodiments, a first card slot 51 is provided on the side of the heat conductor 50 close to the pressure plate 34, and a second card slot 343 is provided on the side of the pressure plate 34 close to the heat conductor 50. The first card slot 51 and the second card slot 343 are arranged opposite to each other, and the first card slot 51 is connected to one end of the elastic member 32, and the second card slot 343 is connected to the other end of the elastic member 32.

[0100] In this way, the elastic member 32 stably connects the heat conducting member 50 and the pressing plate 34 to ensure that the elastic member 32 provides a stable pulling force to the pressing plate 34 , thereby ensuring that the cold storage pack 70 works safely.

[0101] Specifically, in one embodiment, the first slot 51 may be V-shaped with two free ends connected to the bottom of the heat conducting member 50 to stably hook one end of the elastic member 32 , so that the elastic member 32 has good stability and is not easy to fall off.

[0102] It is understandable that one side of the heat conducting member 50 close to the pressure plate 34 may protrude to form a connection hole, that is, to form a V-shaped first slot 51 , thereby ensuring that one end of the elastic member 32 is stably hooked in the first slot 51 .

[0103] Similarly, the second latching groove 343 may be in an inverted V shape, so as to stably hook the other end of the elastic member 32 into the inverted V-shaped connecting hole, thereby ensuring good stability of the elastic member 32 and preventing it from falling off.

[0104] It is understandable that the side of the pressure plate 34 close to the heat conducting member 50 can protrude to form a connecting hole, that is, to form an inverted V-shaped second slot 343, thereby ensuring that the other end of the elastic member 32 is stably hooked in the second slot 343.

[0105] In other embodiments, the first card slot 51 and the second card slot 343 may also be other shapes. Of course, the first card slot 51 and the second card slot 343 may be the same shape or different shapes. It only needs to ensure that the elastic member 32 is stably set. No specific restrictions are made here.

[0106] In one embodiment, the first card slot 51 and the second card slot 343 are located in the working chamber 12 and are arranged opposite to each other to ensure that the elastic member 32 is stably connected to the heat conductive member 50 and the pressure plate 34, thereby ensuring that the elastic member 32 can be movably stretched and changed in the working chamber 12, and then provide a stable pulling force to the pressure plate 34 to ensure that the cold storage pack 70 maintains contact with the heat conductive member 50.

[0107] In one embodiment, the number of the first slots 51 may be one or more, so as to stably support the cold storage pack 70 through at least one elastic member 32 , which is not specifically limited here.

[0108] Similarly, the number of the second card slots 343 can be one or more, as long as the number of the first card slots 51 and the number of the second card slots 343 are equal, which will not be elaborated here.

[0109] In summary, the first clamping slot 51 and the second clamping slot 343 stably hook the two ends of the elastic member 32 to ensure that the pressure plate 34 stably supports the cold storage pack 70, thereby improving the safety of the cold storage pack 70.

[0110] It is worth noting that the first card slot 51 and the second card slot 343 are arranged relative to each other and stably hook the two ends of the elastic member 32 to improve the horizontality of the pressure plate 34, thereby increasing the contact area between the cold storage package 70 and the heat conductive member 50 as much as possible to ensure heat exchange efficiency.

[0111] See also Figure 3 In some embodiments, the cold storage device 100 includes a cold storage component 10, the cold storage component 10 includes a side plate 16, a pressure plate 34 is arranged at the bottom of the cold storage component 10 and forms a working chamber 12 with the side plate 16 and the heat conductive component 50, the pressure plate 34 includes a main body 345, and the main body 345 forms two protrusions 347 along the first direction. The elastic member 32 stretches to connect a side plate 16 and a protrusion 347, so that the main body 345 can movably support at least one cold storage pack 70.

[0112] In this way, the elastic member 32 provides a pulling force to the pressure plate 34 , thereby ensuring that the cold storage pack 70 and the heat conducting member 50 maintain contact, thereby improving the heat exchange efficiency of the cold storage device 100 .

[0113] Specifically, in one embodiment, a working chamber 12 is defined between the heat conductor 50, a plurality of side plates 16 and a pressure plate 34, and the pressure plate 34 is disposed at the bottom of the cold storage component 10, so that the elastic component 32 can be movably stretched and changed at the connection between the side plates 16 and the pressure plate 34, thereby ensuring the movable space required for the phase change of the cold storage agent in the cold storage pack 70, avoiding the cold storage pack 70 from being squeezed and damaged, and thereby improving the safety of the cold storage device 100.

[0114] It can be understood that the volume of the working chamber 12 is adjustable and can be reduced accordingly with the collapse of the cold storage pack 70 or increased accordingly with the bulging of the cold storage pack 70 to avoid the cold storage pack 70 being squeezed and damaged, thereby improving the safety of the cold storage device 100.

[0115] In one embodiment, when the coolant in the cool storage pack 70 is in an initial state (for example, the initial state is liquid), the elastic member 32 passes through the side plate 16 and stretches to connect the side plate 16 and the pressure plate 34, so as to pull the pressure plate 34 by stretching the elastic force to support the cool storage pack 70, so that the cool storage pack 70 abuts against the heat conductive member 50.

[0116] Furthermore, when the coolant in the cool storage bag 70 absorbs cold energy and undergoes a phase change, for example, when the coolant changes from liquid to solid, the cool storage bag 70 changes from a collapsed state to a bulging state, and its volume increases. Force can be applied to both sides of the pressure plate 34 and the heat conductor 50, causing the pressure plate 34 to move away from the heat conductor 50, thereby further stretching the elastic member 32, that is, the stretching elastic force is further increased, thereby ensuring that the cool storage bag 70 and the heat conductor 50 maintain contact.

[0117] It can be understood that the elastic member 32 is arranged inside the side plate 16, that is, a slot is opened inside the side plate 16, which can stably place the elastic member 32 and connect the side plate 16 and the pressure plate 34, so that the pressure plate 34 is pulled by stretching the elastic force, so that the cold storage bag 70 and the heat conductive member 50 maintain contact, thereby ensuring the heat exchange efficiency of the cold storage device 100.

[0118] In one embodiment, the pressing plate 34 includes a body 345 , and the body 345 is configured to provide a supporting force to support the cool storage pack 70 .

[0119] In one embodiment, the main body 345 forms two protrusions 347 along the first direction, so that each protrusion 347 can be connected to one end of each elastic member 32, and the main body 345 can be stably and continuously stretched to maintain the cold storage pack 70 and the heat conductive member 50 in contact, with good safety and stability.

[0120] In one embodiment, the first direction may be the length direction of the body 345 , and the second direction may be the length direction of the side plate 16 , to ensure that the pressing plate 34 is movably connected along the second direction, which is not specifically limited herein.

[0121] See also Figure 3 In some embodiments, the cold storage device 100 includes a force-applying assembly 30 , which includes a buffer member 36 . The buffer member 36 is sandwiched between the protrusion 347 and the side plate 16 and is spaced apart from the elastic member 32 .

[0122] In this way, the wear between the protrusion 347 and the side plate 16 is reduced, thereby ensuring the safe operation of the cold storage device 100.

[0123] Specifically, in one embodiment, the buffer member 36 can be a flexible sealing material and can be arranged between the protrusion 347 and the side plate 16 to reduce the wear between the protrusion 347 and the side plate 16, and can also increase the sealing between the protrusion 347 and the side plate 16, thereby ensuring the safe operation of the cold storage device 100.

[0124] It can be understood that when the coolant in the cool storage pack 70 is in an initial state (for example, the initial state is liquid), the elastic member 32 passes through the side plate 16 and stretches to connect the side plate 16 and the pressure plate 34, wherein the buffer member 36 is clamped between the side plate 16 and the pressure plate 34. At this time, the buffer member 36 is in a compressed deformation state, which can reduce the wear caused by mutual squeezing of the side plate 16 and the pressure plate 34.

[0125] Furthermore, when the refrigerant in the cold storage bag 70 absorbs cold energy and produces a phase change, for example, when the refrigerant changes from liquid to solid, the cold storage bag 70 changes from a collapsed state to a bulging state, and its volume increases. Force can be applied to both sides of the pressure plate 34 and the heat conductor 50, so that the pressure plate 34 moves to the side away from the heat conductor 50, thereby further stretching the elastic member 32. At this time, the pressure plate 34 is away from the side plate 16, so that there is a certain gap between the pressure plate 34 and the side plate 16. The buffer member 36 in a compressed deformation state can at least partially restore the deformation to fill the gap between the pressure plate 34 and the side plate 16, thereby ensuring the internal sealing setting of the cold storage device 100 and good practicality.

[0126] In one embodiment, the buffer member 36 may be made of a rubber material, or other elastically deformable components, which is not specifically limited herein.

[0127] In some embodiments, the elastic member 32 includes one of a spring and an elastic net.

[0128] In this way, pressure is applied to the pressure plate 34 so that the cold storage pack 70 and the heat conducting member 50 are kept in contact with each other, thereby improving the heat exchange efficiency of the cold storage device 100 .

[0129] Specifically, in one embodiment, the elastic member 32 includes one of a spring and an elastic net bag. It can be understood that the elastic member 32 can be a spring to push or pull the pressure plate 34 to maintain the cold storage pack 70 in contact with the heat conductive member 50, ensuring that the cold storage pack 70 can continuously supply cold to the heat conductive member 50 between the collapsed state and the bulged state, thereby ensuring rapid cooling of the target object and improving the user experience.

[0130] In another embodiment, the elastic member 32 includes one of a spring and an elastic mesh bag. It can be understood that the elastic member 32 can also be an elastic mesh bag to pull the pressure plate 34 so that the cold storage bag 70 maintains contact with the heat conductive member 50, ensuring that the cold storage bag 70 can continuously supply cooling to the heat conductive member 50 between the collapsed state and the bulged state, thereby ensuring rapid cooling of the target object and improving the user experience.

[0131] See also Figure 4 and Figure 5 In some embodiments, the force-applying assembly 30 includes a magnetic member 38 and a pressure plate 34. The magnetic member 38 provides a magnetic force to the pressure plate 34 so that the pressure plate 34 applies force to the cold storage pack 70 and / or the heat conductive member 50 so that the cold storage pack 70 and the heat conductive member 50 maintain an abutment state.

[0132] In this way, a magnetic force is generated to keep the cold storage pack 70 and the heat conductive member 50 in contact with each other, thereby ensuring the heat exchange efficiency of the cold storage device 100 .

[0133] Specifically, in one embodiment, the magnetic member 38 may be a magnet, an electromagnet, or other magnetic materials to provide a magnetic force to maintain the cold storage pack 70 in contact with the heat conductive member 50 , without specific limitation herein.

[0134] In one embodiment, the magnetic member 38 and the pressure plate 34 can be made of an integral material, that is, the pressure plate 34 can be made of a magnet, which can reduce the number of parts (such as the magnetic member 38) used while ensuring the realization of the refrigeration function of the cold storage device 100.

[0135] In another embodiment, the magnetic member 38 and the pressure plate 34 can also be made of separate materials, that is, the pressure plate 34 is made of non-magnetic material. The magnetic member 38 needs to be fixed on the pressure plate 34 so that the pressure plate 34 pushes the cold storage bag 70, thereby ensuring that the cold storage bag 70 maintains contact with the heat conductive member 50, thereby ensuring the heat exchange efficiency of the cold storage device 100.

[0136] In another embodiment, the magnetic member 38 and the pressure plate 34 can also be separate materials. For example, the pressure plate 34 is iron, which is a non-magnetic material, and the magnetic member 38 is a magnet. When the magnetic member 38 is close to the pressure plate 34, the pressure plate 34 is magnetized so that the magnetic member 38 and the pressure plate 34 are attracted and fixed to each other, thereby generating a magnetic repulsive force through another magnetic member 38 of the same polarity to push the pressure plate 34, or generating a magnetic attraction force through another magnetic member 38 of a different polarity to pull the pressure plate 34, so that the cold storage bag 70 maintains contact with the heat conductive member 50. No specific restrictions are made here.

[0137] That is, the magnetic force may be a magnetic repulsive force or a magnetic attractive force, so that the pressing plate 34 drives the cold storage bag 70 to move toward the heat conducting member 50 , and no specific limitation is made here.

[0138] See also Figure 4 and Figure 6 In some embodiments, the cold storage device 100 includes a cold storage component 10, which includes a bottom plate 14. A pressure plate 34 is arranged on the top of the force-applying component 30. The bottom plate 14 is arranged opposite to the pressure plate 34 and is located at the bottom of the force-applying component 30. The pressure plate 34 and the bottom plate 14 define a movement space. There are two magnetic members 38 with the same polarity. The two magnetic members 38 are located at both ends of the movement space and are respectively arranged at the bottom of the pressure plate 34 and the top of the bottom plate 14, so that the pressure plate 34 can movably support at least one cold storage pack 70.

[0139] In this way, the magnetic member 38 provides a thrust to the pressure plate 34 , thereby ensuring that the cold storage pack 70 and the heat conducting member 50 maintain contact, thereby improving the heat exchange efficiency of the cold storage device 100 .

[0140] Specifically, in one embodiment, the bottom plate 14 is disposed at the bottom of the cold storage component 10 , and can provide support and sealing conditions for the cold storage device 100 , thereby ensuring safe operation of the cold storage device 100 .

[0141] In one embodiment, a movement space is defined between the pressure plate 34 and the base plate 14 so that the magnetic member 38 disposed at the bottom of the pressure plate 34 can move in the second direction within the movement space, thereby ensuring that the pressure plate 34 can movably push the cold storage pack 70 so that the cold storage pack 70 maintains contact with the heat conductive member 50.

[0142] It can be understood that the movement space can ensure that the pressure plate 34 can movably support the cold storage pack 70, so that the cold storage pack 70 is pressed against the heat conductor 50 and maintains contact, which is practical.

[0143] In one embodiment, when the coolant in the coolant pack 70 is in an initial state (e.g., liquid), the two magnetic members 38 are located at both ends of the motion space along the second direction and are respectively connected to the pressure plate 34 and the bottom plate 14. The magnetic repulsion forces push the pressure plate 34 to support the coolant pack 70, causing the coolant pack 70 to abut against the thermal conductive member 50. In other words, the magnetic repulsion at this point is sufficient to ensure that the coolant pack 70 abuts against the thermal conductive member 50.

[0144] Furthermore, when the coolant in the cool storage bag 70 absorbs cold energy and produces a phase change, for example, when the coolant changes from liquid to solid, the cool storage bag 70 changes from a collapsed state to a bulging state, and its volume increases. Force can be applied to both sides of the pressure plate 34 and the heat conductor 50, so that the pressure plate 34 moves to the side away from the heat conductor 50, thereby making the two magnetic parts 38 closer together, that is, the magnetic repulsion force is further increased, thereby ensuring that the cool storage bag 70 and the heat conductor 50 maintain contact.

[0145] In summary, the two magnetic parts 38 are located at both ends of the movement space along the second direction and are respectively connected to the pressure plate 34 and the bottom plate 14, wherein the movement space and the working chamber 12 are separated by the pressure plate 34 to form a magnetic repulsive force to push the pressure plate 34 to move in the direction of the heat conductor 50, thereby ensuring that the cold storage bag 70 and the heat conductor 50 maintain contact, thereby ensuring the heat exchange efficiency of the cold storage device 100.

[0146] See also Figure 5 In some embodiments, the cold storage device 100 includes a cold storage component 10, which includes a bottom plate 14. The pressure plate 34 is arranged at the bottom of the force-applying component 30 and opposite to the heat conductor 50. The bottom plate 14 is arranged opposite to the pressure plate 34 and is located at the bottom of the cold storage device 100. The pressure plate 34 and the bottom plate 14 define a movement space. There are two magnetic members 38 with opposite polarities. The two magnetic members 38 are located at both ends of the working chamber 12 and are respectively arranged at the bottom of the heat conductor 50 and the top of the pressure plate 34, so that the pressure plate 34 can movably support at least one cold storage bag 70 in the movement space.

[0147] In this way, the magnetic member 38 provides a pulling force to the pressure plate 34 , thereby ensuring that the cold storage pack 70 and the heat conducting member 50 maintain contact, thereby improving the heat exchange efficiency of the cold storage device 100 .

[0148] Specifically, in one embodiment, a working chamber 12 is defined between the heat conductive member 50 and the pressure plate 34, so that the magnetic member 38 arranged on the top of the pressure plate 34 can move along the second direction in the working chamber 12, thereby ensuring that the pressure plate 34 can movably push the cold storage pack 70 so that the cold storage pack 70 maintains contact with the heat conductive member 50.

[0149] It can be understood that the volume of the working chamber 12 is adjustable and can be reduced accordingly with the collapse of the cold storage pack 70 or increased accordingly with the bulging of the cold storage pack 70 to avoid the cold storage pack 70 being squeezed and damaged, thereby improving the safety of the cold storage device 100.

[0150] In one embodiment, when the coolant in the cool storage pack 70 is in an initial state (for example, the initial state is liquid), the two magnetic members 38 are located at both ends of the working chamber 12 along the second direction and are respectively connected to the heat conductive member 50 and the pressure plate 34, so as to pull the pressure plate 34 by magnetic attraction to support the cool storage pack 70, so that the cool storage pack 70 is in contact with the heat conductive member 50.

[0151] Furthermore, when the coolant in the cool storage bag 70 absorbs cold energy and undergoes a phase change, for example, when the coolant changes from liquid to solid, the cool storage bag 70 changes from a collapsed state to a bulging state, and its volume increases. Force can be applied to both sides of the pressure plate 34 and the heat conductor 50, so that the pressure plate 34 moves toward the side away from the heat conductor 50, thereby making the two magnetic parts 38 relatively distant. That is, it is only necessary to ensure that the magnetic attraction force at this time is sufficient to maintain the cool storage bag 70 in contact with the heat conductor 50, so as to ensure that the cool storage bag 70 always maintains contact with the heat conductor 50 during the refrigeration process of the cool storage device 100.

[0152] In one embodiment, a movement space is defined between the pressure plate 34 and the bottom plate 14, that is, the working chamber 12 and the movement space are separated by the pressure plate 34. When the cold storage pack 70 changes from a collapsed shape to a bulged shape, the volume of the working chamber 12 increases, and the volume of the movement space decreases, thereby ensuring that the pressure plate 34 can be movably arranged inside the cold storage component 10.

[0153] In summary, the two magnetic parts 38 are located at both ends of the working chamber 12 along the second direction and are respectively connected to the heat conductor 50 and the pressure plate 34, wherein the working chamber 12 and the movement space are separated by the pressure plate 34 to form a magnetic attraction force to pull the pressure plate 34 and the heat conductor 50 to clamp the stable cold storage bag 70, thereby ensuring that the cold storage bag 70 and the heat conductor 50 maintain abutment, thereby ensuring the heat exchange efficiency of the cold storage device 100.

[0154] See also Figures 4 to 6In some embodiments, the cold storage device 100 includes a support member 80 , which is disposed in the movement space. When the two magnetic members 38 are demagnetized, the support member 80 supports the pressure plate 34 and at least one cold storage pack 70 .

[0155] In this way, the magnetic member 38 is ensured to be stably disposed in the cold storage device 100 , thereby improving the safety of the cold storage device 100 .

[0156] Specifically, in one embodiment, the support member 80 is arranged in the movement space and can be used to support the pressure plate 34 and at least one cold storage pack 70 to prevent the cold storage pack 70 from falling directly onto the bottom plate 14 and causing damage, thereby improving the safety of the cold storage pack 70.

[0157] In one embodiment, the support member 80 can be a split bracket (not shown), for example, the support member 80 can be a fence frame, which can provide support while reducing weight, saving materials and reducing costs, thereby ensuring the safe operation of the cold storage pack 70.

[0158] In another embodiment, Figure 7 and Figure 8 As shown, the support member 80 can also be an integrated bracket, for example, the support member 80 is integrally formed with the base plate 14, wherein the support member 80 can be strip-shaped or block-shaped to ensure the safe operation of the cold storage pack 70, which will not be repeated here.

[0159] It can be understood that by providing the support member 80 , the situation in which the two magnetic members 38 are suddenly demagnetized and cause the cold storage package 70 to fall can be avoided, thereby ensuring the safe operation of the cold storage package 70 and further improving the safety of the cold storage device 100 .

[0161] The cooling element 10 includes a bottom plate 14 , and fasteners 19 sequentially connect the bottom plate 14 and the side plates 16 .

[0162] In this way, the overall stable connection of the cooling element 10 is ensured, thereby providing a safe and stable working environment for the cooling pack 70 .

[0163] Specifically, in one embodiment, the heat conducting member 50 is connected to the side plate 16 , and the top cover 18 is covered on the heat conducting member 50 , so that the heat conducting member 50 is sandwiched between the top cover 18 and the side plate 16 , thereby improving the connection stability of the heat conducting member 50 .

[0164] In one embodiment, the fastener 19 sequentially connects the top cover 18, the heat conductor 50 and the side plate 16, further improving the connection stability of the heat conductor 50 in the cold storage device 100, thereby ensuring that the target object is stably placed on the heat conductor 50 and quickly exchanges heat.

[0165] In one embodiment, the fasteners 19 sequentially connect the bottom plate 14 and the side plate 16 so that the bottom of the cold storage device 100 is stably connected, thereby ensuring the overall stable connection of the cold storage device 100 and providing a safe and stable working environment for the cold storage pack 70.

[0166] In one embodiment, the fastener 19 may be a screw or other connecting member to ensure that the cold storage device 100 is stably connected as a whole, and no specific limitation is made here.

[0167] Optionally, the fastener 19 may be a hexagon socket screw, so that the hexagon socket screw is hidden and connected inside the cold storage device 100 , thereby improving the appearance of the cold storage device 100 while ensuring the connection effect.

[0168] In one embodiment, please combine Figure 9 The top cover 18 is in a hollow frame shape and covers the heat conducting member 50, so that the heat conducting member 50 can be exposed from the middle hollow position of the top cover 18, thereby ensuring the stable placement of the target object and rapid heat exchange, and having good practicality.

[0169] In certain embodiments, the top cover 18 , the side panels 16 , and the pressure plate 34 enclose a working chamber 12 .

[0170] In this way, a safe working environment can be provided for the cold storage pack 70 , and the heat exchange efficiency of the cold storage pack 70 can be ensured.

[0171] Specifically, in one embodiment, the top cover 18, the side panels 16 and the pressure plate 34 enclose the working chamber 12 to form a movable space for placing the cold storage pack 70, so that the cold storage pack 70 is isolated from the external environment, thereby reducing the cold loss efficiency of the cold storage pack 70, and further improving the heat exchange efficiency between the cold storage pack 70 and the heat conductor 50.

[0172] In one embodiment, the volume of the working chamber 12 is adjustable. That is, the volume of the working chamber 12 can change accordingly according to the expansion or contraction of the cold storage pack 70, thereby ensuring the safe operation of the cold storage pack 70 and preventing the cold storage pack 70 from being squeezed and damaged.
