Description

Cooler container

[0001] The present invention relates to a refrigerated container.

[0002] A cold chain system is a system that consistently controls temperature from raw materials through production and processing to the final consumer. A cold chain system can maintain the target temperature of raw materials, products, and other items.

[0003] In order to control the temperature of goods in the cold chain system, cold storage facilities and vehicles equipped with refrigeration facilities are required to store the goods.

[0004] In the cold chain system, installation and maintenance costs for vehicles equipped with cold storage facilities and refrigeration facilities are required.

[0005] The background technology described above is technology that the inventor possessed or acquired in the process of deriving the disclosure of the present application, and cannot necessarily be said to be publicly known technology disclosed to the general public prior to the present application.

[0006] Refrigerated or frozen demand can fluctuate by day of the week and season. For example, in weekly delivery volumes, demand for refrigerated or frozen deliveries on Sundays is approximately 94% higher than demand for refrigerated or frozen deliveries on Tuesdays. Furthermore, demand for refrigerated or frozen deliveries in July is approximately 29.7% higher than demand for refrigerated or frozen deliveries in November.

[0007] Cold chain systems require refrigerated / frozen warehouses to store goods and vehicles equipped with refrigeration facilities. Because refrigerated / frozen warehouses and vehicles equipped with refrigeration facilities are limited, existing cold chain systems struggle to meet fluctuating demand.

[0008] Additionally, in the cold chain system, the construction and maintenance costs of refrigerated / freezer warehouses, installation costs of vehicles equipped with refrigeration facilities, and fuel costs are greater than those of general warehouses and vehicles.

[0009] According to one embodiment of the present invention, a cold storage container capable of maintaining an internal temperature at a target temperature can be provided.

[0010] According to one embodiment of the present invention, it is possible to provide a refrigerated container that can respond to the fluid demand for frozen or refrigerated delivery and is cheaper than a vehicle equipped with a frozen / freezer warehouse and refrigeration facilities.

[0069]

[0070] Figure 1 is a perspective view (100) of a cooling container according to various embodiments.

[0071] Referring to FIG. 1, a cooling container according to various embodiments may include a body (101), a cover (103), and a control module.

[0072] For example, the control module (105) may include a processor and memory.

[0073] A processor may, for example, execute software (e.g., a program) to control at least one other component (e.g., a hardware or software component) of a device (e.g., a cooler) connected to the processor, and may perform various data processing or calculations. According to one embodiment, as at least part of the data processing or calculation, the processor may store instructions or data received from another component (e.g., a sensor module or a communication module) in volatile memory, process the instructions or data stored in the volatile memory, and store the resulting data in non-volatile memory. According to one embodiment, the processor may include a main processor (e.g., a central processing unit or an application processor) or an auxiliary processor (e.g., a graphics processing unit, a neural processing unit (NPU), an image signal processor, a sensor hub processor, or a communication processor) that can operate independently of or in conjunction with the main processor. For example, when a device includes a main processor and an auxiliary processor, the auxiliary processor may be configured to use less power than the main processor or to be specialized for a given function. The auxiliary processor may be implemented separately from the main processor or as a part thereof.

[0074] Memory can store various data used by at least one component of the device (e.g., a processor or a sensor). The data can include, for example, software (e.g., a program) and input or output data for commands associated therewith. The memory can include volatile memory or non-volatile memory.

[0075] For example, the main body (101) may have an open upper surface and include a storage space inside. For example, the main body (101) may include a lower portion and an upper portion. The outer shape of the lower portion may correspond to the inner shape of the upper portion.

[0076] For example, the outer area and outer shape of the lower portion may correspond to the inner area and inner shape of the upper portion. For example, the outer area of ​​the lower portion may represent an area according to the outer surface of the lower portion. The inner area of ​​the upper portion may represent an area according to the inner surface of the upper portion. Since the outer area and outer shape of the lower portion correspond to the inner area and inner shape of the upper portion, a plurality of main bodies (101) may be stacked. For example, the lower portion of another main body (101) may be inserted into the interior of the upper portion of the main body (101).

[0077] The shapes of the upper and lower parts of the main body (101) illustrated in Fig. 1 are exemplary, and the shapes of the upper and lower parts of the main body (101) are not limited to the example illustrated in Fig. 1. For example, the shapes of the upper and lower parts may have various shapes, such as a regular hexagon, a regular pentagon, etc.

[0078] For example, the cover (103) can shield the upper surface of the main body (101). For example, the cover (103) can be coupled to the upper side of the main body (101) to shield the opened upper surface of the main body (101).

[0079] For example, the insulated container can identify the temperature of the storage space. For example, the insulated container can include at least one sensor for identifying the temperature of the storage space. The insulated container can use the at least one sensor to identify the temperature at at least one location in the storage space. For example, the insulated container can identify the temperature of the lower surface and upper surface of the storage space. The insulated container can identify the temperature of the middle depth of the storage space.

[0080]

[0081] FIG. 2 is a top view of a cold storage container according to various embodiments.

[0082] Figure 2 shows a top view of the body (101) of the cold container with the cover (103) removed.

[0083] Referring to FIG. 2, a cold storage container according to various embodiments may include a refrigerant space in which a refrigerant is disposed, and a cooling module (201, 203) disposed in a storage space. For example, the cooling module (201, 203) may include a refrigerant space that is insulated from the outside. For example, the refrigerant may include a phase change material (PCM). A PCM is a material that absorbs or releases energy during a phase transition. When a PCM cooled to a solid undergoes a phase transition to a liquid, the PCM may absorb heat from the surroundings.

[0084] For example, a PCM may contain propylene glycol food (PG-F). PG-F has a pH of 7, a melting / freezing point of -59˚C, an initial boiling point and boiling point range of 186 to 189˚C, and a flash point of 99˚C.

[0085] For example, the cold storage container may be formed in a cooling module (201, 203) and may include an opening and closing portion that forms a path from the refrigerant to the storage space in an open state and insulates the refrigerant from the storage space in a closed state.

[0086] Referring to FIG. 2, a cooling module (201, 203) according to one embodiment may be detachably attached to a main body (101). For example, the cooling module (201, 203) may be coupled to a fitting groove (211-1, 211-3, 213-1, 213-3) formed on a side surface of the main body (101). FIG. 2 illustrates an example in which a cooling module (201, 203) according to one embodiment has fitting grooves (211-1, 211-3, 213-1, 213-3) formed on one side surface and the other side surface opposite to the one side surface, and two cooling modules (201, 203) are coupled to the fitting grooves (211-1, 211-3, 213-1, 213-3).

[0087] The detachable cooling modules (201, 203) on the main body (101) illustrated in FIG. 2 are exemplary and are not limited to the examples illustrated in FIG. 2. For example, the main body (101) may further include a fixing device on the upper side of the main body (101) to prevent the cooling modules (201, 203) from detaching.

[0088] Referring to FIG. 2, the separated cooling modules (201, 203) can be stored in the storage space of the main body (101). As shown in FIG. 2, the cooling modules (201, 203) can be stored diagonally in the storage space.

[0089] Referring to Fig. 2, the outer shape of the lower part can correspond to the inner shape of the upper part. By inserting the lower part of another main body (101) into the upper part of the main body (101), a plurality of main bodies (101) can be stacked.

[0090]

[0091] FIG. 3 is a cross-sectional view of a cooling container according to various embodiments.

[0092] For example, the cold storage container may be formed in a cooling module (201) and may include an opening and closing portion that forms a path from the refrigerant to the storage space in an open state and insulates the refrigerant from the storage space in a closed state.

[0093] For example, the opening / closing unit may include an opening / closing device. The opening / closing device may operate under the control of a cold container (or processor). Depending on the operation of the opening / closing device, the open or closed state of the opening / closing unit may be determined.

[0094] For example, the cover (103) may include a control module (105). A connector (or plug) may be arranged on the lower side of the cover (103) (or the side in contact with the cooling module (201)). A plug (or connector) may be arranged on the upper side of the cooling module (201) (or the side in contact with the cover (103)). When the cover (103) is coupled to the main body (101), the connector (or plug) on ​​the lower side of the cover (103) and the plug (or connector) on the upper side of the cooling module (201) may be connected. The control module (105) and the cooling module (201) may be electrically connected through the connector and the plug. The control module (105) may control the cooling module (201) (or the opening and closing part) through the connector and the plug.

[0095] For example, the cooling module (201) may include a plug. The cooling module (201) may be connected to a connector formed on the inner surface of the main body (101) through the plug and may be electrically connected to the control module (105).

[0096] For example, the opening / closing device may include a motor and a shield. The motor may move the shield under the control of the cold container.

[0097] In the above description, the case where the switching device includes a motor and a shielding wall is described, but the switching device is not limited thereto, and various devices for shielding or opening the cooling module (201) can be applied.

[0098] For example, the opening / closing unit can open or close the passage between the refrigerant and the storage space within the cooling module (201). For example, when the opening / closing unit is open, air cooled by the refrigerant can move to the storage space. When the opening / closing unit is open, the cooling module (201) can provide air cooled by the refrigerant to the storage space. The cooling module (201) can provide cooled air to the storage space along the passage formed by the opening / closing unit between the storage space and the refrigerant space.

[0099] For example, the opening / closing member may form a flow path toward the lower side of the storage space when in an open state. For example, the opening / closing member may be formed on the lower side of the cooling module (201). When the opening / closing member is in an open state, air cooled by the refrigerant may be transmitted along the flow path formed toward the lower side of the storage space.

[0100] For example, the main body (101) may include a conductive plate (131) formed on the surface of the lower side and / or the inner side of the storage space. For example, the conductive plate (131) may be formed at a position corresponding to a flow path. Cooled air moved along the flow path may contact the conductive plate (131). The conductive plate (131) may be cooled by heat conduction between the cooled air and the conductive plate (131).

[0101] For example, cooled air moving in the refrigerant space can come into contact with a conductive plate (131) formed on the surface of the inner side of the storage space. The conductive plate (131) formed on the surface of the lower side of the storage space can be connected to the conductive plate (131) formed on the surface of the inner side of the storage space. As the conductive plate (131) formed on the surface of the inner side of the storage space is cooled, the conductive plate (131) formed on the surface of the lower side of the storage space can be cooled.

[0102] When storing objects in a storage space, cooled air discharged along the flow path can move upwards along the surface of the objects. The upper side of the storage space (or the upper side of the objects) can be cooled by the movement of cooled air.

[0103] As described above, the lower and / or upper portions of the storage space can be cooled by the cooled air moving along the duct. When the opening is open, the entire storage space (or the upper and / or lower portions of the storage space) can be cooled by the cooled air.

[0104] For example, if the opening is closed, the refrigerant space may be insulated from the storage space. If the opening is closed, heat exchange between the refrigerant space and the storage space may be blocked.

[0105] Referring to FIG. 3, the refrigerated container according to various embodiments can control the opening / closing operation based on the temperature of the storage space. For example, the refrigerated container can control the opening / closing operation based on the temperature of the storage space and the target temperature.

[0106] For example, a cold storage container can control its opening and closing mechanism so that the temperature of the storage space remains below a target temperature. For example, if the target temperature is -10°C, the cold storage container can control its opening and closing mechanism to open when the temperature of the storage space exceeds -10°C.

[0107] For example, the cold storage container can control the opening / closing mechanism based on the temperature of the storage space being within a target temperature range (or a set range). For example, if the target temperature is -10°C and the threshold is -1°C, and the temperature of the storage space is above -9°C, the cold storage container can control the opening / closing mechanism to remain open until the temperature of the storage space is below -11°C.

[0108] For example, if the target temperature is -10°C and the threshold is -1°C, the cold storage container can control the opening and closing so that the temperature of the storage space is above -11°C and below -9°C.

[0109] The above-described operation of the cold storage container controlling the opening and closing is exemplary and is not limited to the above-described example, and the cold storage container can control the opening and closing in various ways.

[0110] For example, a refrigerant may contain a substance with a freezing point lower than the target temperature. A cold storage container may be a device designed to maintain the temperature of a stored item at the target temperature. The refrigerant may contain a phase change material (or PCM). The heat absorbed during the phase transition of the refrigerant can be utilized to cool the temperature inside the cold storage container.

[0111] According to one embodiment, the insulated container can utilize a refrigerant containing a substance having a freezing point lower than the target temperature, since the refrigerant is located within the insulated cooling module (201). For example, if the target temperature is -10°C, the insulated container can maintain the temperature of the storage space at the target temperature using a refrigerant (or PCM, phase change material) having a freezing point of -20°C.

[0112] The insulated container can maintain the temperature of the storage space at a target temperature by controlling the open or closed state of the opening and closing portion. The insulated container can maintain the temperature of the storage space at the target temperature even if the freezing point of the refrigerant is lower than the target temperature. The insulated container can prevent the temperature of the storage space from being overcooled by controlling the open or closed state of the opening and closing portion. Since the freezing point of the refrigerant is lower than the target temperature, the time for which the insulated container can maintain the temperature of the storage space at the target temperature can be extended.

[0113] In the above examples, the target temperature and the freezing point of the refrigerant are exemplary and are not limited to the above examples. For example, the refrigerant may include a substance with a freezing point lower than the target temperature (e.g., 10°C, 20°C, 30°C, etc.). The type of refrigerant may be determined based on the target temperature and the retention time required to maintain the storage space at the target temperature. Depending on the target temperature and / or retention time, a substance to be used as the refrigerant may be selected from among a plurality of substances having different freezing points.

[0114] According to one embodiment, a cold storage container can identify the temperature of a storage space at set intervals (e.g., every 30 minutes, every hour, etc.). For example, the cold storage container can identify the temperature of the storage space using a sensor.

[0115] For example, the insulated container can determine whether to open the door and the opening time based on the identified temperature and the target temperature. For example, the insulated container can determine to open the door when the identified temperature is higher than the target temperature.

[0116] For example, the cold storage container may determine to open the door when the identified temperature falls within a set range. For example, the set range may be a temperature range set based on a target temperature (e.g., within 2°C of the target temperature, (target temperature) - 1°C or more, (target temperature) + 1°C or less).

[0117] For example, the insulated container can determine the opening time of the opening / closing part based on the identified temperature and the target temperature. The insulated container can determine the opening time based on the size of the difference between the target temperature and the identified temperature. For example, if the difference between the target temperature and the identified temperature is large, the insulated container can determine a longer opening time. For example, the insulated container can determine a longer opening time when the target temperature is -10°C and the temperature of the storage space (or the identified temperature) is -11°C than when the target temperature is -10°C and the temperature of the storage space is -10.5°C.

[0118] For example, the coolant container can identify the temperature of the coolant space. For example, the cooling module (201) can include a sensor for identifying the temperature of the coolant space. The coolant container can identify the temperature of the coolant space using the sensor installed in the coolant space.

[0119] For example, the insulated container can determine the expected time it will take to maintain the storage space at the target temperature based on the temperature of the refrigerant space, the temperature of the storage space, and the target temperature. For example, if the temperature of the refrigerant space is -20°C, the temperature of the storage space is -11°C, and the target temperature is -10°C, the insulated container can determine the expected time as 72 hours.

[0120] The description of the above-mentioned operation of the cold storage container for determining whether to open the opening part and the opening time and the operation of determining the expected time is exemplary and is not limited to the above-mentioned example.

[0121] For example, the cold storage container may include a vent formed on an inner side. The cold storage container may include an external vent (123) formed on an outer side corresponding to the position of the internal vent (121). The cold storage container may include a passage (125) formed between the internal vent (121) and the external vent (123). Air in the storage space of the cold storage container may be discharged to the outside through the internal vent (121), the passage (125), and the external vent (123). Through the internal vent (121), the passage (125), and the external vent (123) of the cold storage container, a pressure difference between the inside and the outside of the cold storage container may be eliminated.

[0122] The internal vent (121) and external vent (123) of the cold storage container can block and / or minimize heat exchange between the inside and outside of the cold storage container and enable air flow between the inside and outside, thereby relieving the pressure difference between the inside and outside.

[0123] For example, the body (101), the cover (103), and / or the cooling module (201) may include an insulating material. For example, the insulating material may be EPS (Expanded Polystyrene), EPP (Expanded Polypropylene), PIR (Polyisocyanurate), or the like.

[0124] Referring to Fig. 3, the outer surface of the lower portion (111) may correspond to the inner surface of the upper portion (113). The outer shape of the lower portion (111) may correspond to the inner shape of the upper portion (113). The lower portion (111) of the main body (101) may be inserted into the upper portion (113) of another main body.

[0125]

[0126] Fig. 4 is a drawing showing a cooling module (201) of a cold storage container according to various embodiments. Fig. 4 is an enlarged drawing of part A of Fig. 3.

[0127] Referring to FIG. 4, a cooling module (201) according to one embodiment may include a refrigerant space. The cooling module (201) may include a refrigerant in the refrigerant space. The refrigerant may be separated or inserted into the cooling module (201). The refrigerant may be separated, cooled, and then inserted into the refrigerant space.

[0128] For example, the cooling module (201) may form a flow path toward the lower side of the storage space when the opening / closing part is in the open state. For example, in FIG. 4, when the opening / closing part is in the open state, a flow path may be formed toward the lower side of the cooling module (201). When the opening / closing part is in the open state, a flow path may be formed toward the conductive plate (131) formed in the lower side of the cooling module (201). When the opening / closing part is in the open state, cold air in the refrigerant space may flow toward the conductive plate (131).

[0129] The conductive plate (131) can exchange heat with air transferred from the refrigerant space. The conductive plate (131) can be cooled to lower the temperature of the lower surface of the storage space. As shown in FIGS. 3 and 4, the conductive plate (131) can be formed on the inner surface of the lower portion, the lower surface, and the lower side of the cooling module (201).

[0130] For example, as shown in Fig. 4, air moving in the refrigerant space can move upward (133). For example, when an item is placed in the storage space, air moving in the refrigerant space can move upward (133) of the item.

[0131] As described above, air (e.g., cold air) moving in the refrigerant space can lower the temperatures of the upper and lower portions of the storage space. The air moving in the refrigerant space can cool the conductive plate (131), thereby cooling the lower portion of the storage space. The air moving in the refrigerant space can move upward (133) along the product, thereby cooling the upper portion of the storage space.

[0132] Air in the storage space can move to the outside through the internal vent (121), the passage, and the external vent (123). For example, when a pressure difference occurs between the storage space and the outside, air in the storage space can be discharged to the outside through the internal vent (121), the passage, and the external vent (123). The internal vent (121) and the external vent (123) can be formed of a material that allows air to pass through and blocks and / or minimizes heat exchange.

[0133] For example, the cooling module (201) may include a fan for discharging air from the refrigerant space into the storage space in an open state. For example, the fan may operate in an open state. The fan discharges air from the refrigerant space into the storage space in an open state, thereby efficiently cooling the storage space.

[0134]

[0135] Figure 5 is a side view of another cold storage container according to various embodiments.

[0136] As shown in Fig. 5, the main body (101) may include a lower part (111) and an upper part (113). The lower part (111) of the main body (101) may be inserted into the upper part (113) of another main body (101) and laminated.

[0137] As shown in Fig. 5, an external vent (123) may be formed on the outer surface of the main body (101). The external vent (123) may be formed on the outer side corresponding to the internal vent (121). A flow path (125) may be formed between the external vent (123) and the internal vent (121). Through the internal vent (121), the flow path (125), and the external vent (123), air in the storage space may flow with external air.

[0138]

[0139] FIG. 6 is a drawing showing an internal vent (121) and an external vent (123) of a cold container according to various embodiments.

[0140] In Fig. 6, A may represent a storage space (or the inside of a cold storage container), and B may represent the outside. Air in the storage space of A may be discharged to the outside B through an internal vent (121), a passage (125), and an external vent (123). External air in B may be introduced into the inside A through an external vent (123), a passage (125), and an internal vent (121).

[0141] FIG. 6 is a drawing showing an example of a euro (125) according to various embodiments, and the shape of the euro (125) is not limited to the embodiment shown in FIG. 6. For example, the euro may include various shapes such as a winding shape, a curved shape, etc.

[0142]

[0143] FIG. 7 is a drawing showing a solar panel (141) and a fan (143) of a cold storage container according to various embodiments.

[0144] For example, the cover (103) may include a solar panel (141) on the upper side for generating electricity using sunlight. The cover (103) may include a fan (143) formed on the lower side. The fan (143) formed on the lower side of the cover (103) may operate using the electricity generated by the solar panel (141). The fan (143) formed on the lower side of the cover (103) may operate when the cover (103) is coupled to the main body (101).

[0145] A fan (143) formed on the lower surface of the cover (103) can circulate the air in the storage space by flowing the air in the storage space. The fan (143) can circulate the air in the storage space to make the temperature inside the storage space more uniform.

[0146]

[0147] In the following drawings 8 to 16, an example of a cold storage container that cools a storage space by using a second conductive plate formed by penetrating the refrigerant within the cooling module and a first conductive plate formed at the bottom of the cover is described.

[0148] With respect to the cold storage containers illustrated in FIGS. 8 to 16 below, content substantially identical to the description of the cold storage containers illustrated in FIGS. 1 to 7 may be omitted. Accordingly, even if content is not described with respect to the cold storage containers illustrated in FIGS. 8 to 16, the description of the cold storage containers illustrated in FIGS. 1 to 7 may be substantially identically applied.

[0149] For example, the cold storage containers illustrated in FIGS. 8 to 16 may include upper and lower portions that are substantially the same as the upper portion (e.g., the upper portion (113) of FIGS. 3, 4, and 5) and lower portion (e.g., the lower portion (111) of FIGS. 3, 4, and 5) of the cold storage containers illustrated in FIGS. 1 to 7. In addition, the cooling module of the cold storage containers illustrated in FIGS. 8 to 16 may be detachably attached to the main body and may be coupled to a fitting groove formed in the main body.

[0150]

[0151] Figure 8 is a drawing showing a cooling container according to various embodiments.

[0152] Referring to FIG. 8, a cooling container according to various embodiments may include a body (301), a cover (303), and a cooling module (311).

[0153] For example, the main body (301) may have an open upper surface and include a storage space inside. For example, the main body (301) may include a lower portion and an upper portion. The outer shape of the lower portion may correspond to the inner shape of the upper portion.

[0154] For example, the outer area and outer shape of the lower portion may correspond to the inner area and inner shape of the upper portion. For example, the outer area of ​​the lower portion may represent an area according to the outer surface of the lower portion. The inner area of ​​the upper portion may represent an area according to the inner surface of the upper portion. Since the outer area and outer shape of the lower portion correspond to the inner area and inner shape of the upper portion, a plurality of main bodies (301) may be stacked. For example, the lower portion of another main body (301) may be inserted into the interior of the upper portion of the main body (301).

[0155] For example, the cover (303) can shield the upper surface of the main body (301). For example, the cover (303) can be coupled to the upper side of the main body (301) to shield the opened upper surface of the main body (301).

[0156] For example, the cover (303) may include a first conductive plate. For example, the first conductive plate may be positioned on the lower surface of the cover (303). The first conductive plate may be connected to a second conductive plate formed by penetrating the refrigerant and cooled. The cooled first conductive plate may cool the storage space.

[0157] For example, the cover (303) may include a connecting member (321). The connecting member (321) may control the connection between the first conductive plate of the cooling module (311) and the second conductive plate formed at the bottom of the cover (303).

[0158] For example, in the first state, the connecting member (321) can separate or space the first conductive plate and the second conductive plate. In the first state, the connecting member (321) can shield the cooling module (311).

[0159] For example, in the second state, the connecting member (321) can connect the first conductive plate and the second conductive plate. When the first conductive plate and the second conductive plate are connected, the second conductive plate can exchange heat with the first conductive plate. Since the first conductive plate is formed by penetrating the refrigerant, the temperature of the first conductive plate can be lower than the temperature of the second conductive plate. The second conductive plate can be cooled by exchanging heat with the first conductive plate.

[0160] For example, the connection of a first conductive plate and a second conductive plate may indicate that the first conductive plate and the second conductive plate exchange heat. If the temperature of the first conductive plate is higher than that of the second conductive plate, the first conductive plate may be cooled.

[0161] The first conductive plate and the second conductive plate may be directly connected or indirectly connected. For example, the first conductive plate may be connected to the second conductive plate through a component included in the connecting member (e.g., a third conductive plate).

[0162] For example, the cooling module (311) may include a refrigerant space in which a refrigerant is disposed and may be disposed in a storage space. For example, the cooling module (311) may include a second conductive plate positioned to penetrate the refrigerant.

[0163] For example, the cold storage container may include a control module. With respect to the control module of the cold storage container of FIG. 8, the description of the control module of the cold storage container described in FIG. 1 (e.g., the control module (105) of FIG. 1) may be substantially identically applied.

[0164] For example, the insulated container can identify the temperature of the storage space. For example, the insulated container can include at least one sensor for identifying the temperature of the storage space. The insulated container can use the at least one sensor to identify the temperature at at least one location in the storage space. For example, the insulated container can identify the temperature of the lower surface and upper surface of the storage space. The insulated container can identify the temperature of the middle depth of the storage space.

[0165] For example, the cold storage container can control the connecting member (321) based on the temperature of the storage space. For example, the control module can control the operating state of the connecting member (321) based on the temperature of the storage space. The control module can control the connecting member (321) to a first state or a second state based on the temperature of the storage space.

[0166] For example, the cooling module (311) may include a refrigerant placed in a refrigerant space. The refrigerant space of the cooling module (311) may be formed of an insulating member. The insulating member may block and / or minimize heat exchange between the refrigerant space and the outside, thereby maintaining the temperature of the refrigerant.

[0167] The cold storage container illustrated in Fig. 8 can cool a storage space by using a first conductive plate under a cover (303) and a second conductive plate of a cooling module (311). For example, the cold storage container can control the connection between the first conductive plate and the second conductive plate by controlling the connection member (321) to a first state or a second state. The cold storage container can cool a storage space by controlling the first conductive plate and the second conductive plate.

[0168]

[0169] Fig. 9 is a drawing showing a cover (303) and a cooling module (311) of a cold storage container according to various embodiments. Fig. 9 is an example showing the cover (303) and the cooling module (311) when the cover (303) of Fig. 8 is coupled to the main body (301).

[0170] Referring to FIG. 9, the cover (303) may include a first conductive plate (331) formed at the bottom. When the cover (303) is coupled to the main body (301), the connecting member (321) may be coupled to the cooling module (311). The connecting member (321) may control the connection between the first conductive plate and the second conductive plate (331) within the cooling module (311) depending on the operating state. For example, the cold storage container (or the control module of the cold storage container) may control the operating state of the connecting member.

[0171]

[0172] FIG. 10 and FIG. 11 are drawings showing a connecting member (321) and a cooling module (311) according to various embodiments.

[0173] Referring to FIGS. 10 and 11, the cooling module (311) according to various embodiments may include an opening / closing device (313). For example, the opening / closing device (313) may open the cooling module (311) when the cover (303) is coupled to the main body (301). For example, the opening / closing device (313) may shield the cooling module (311) when the cover (303) is separated from the main body (301).

[0174] Fig. 10 is a drawing showing a state (1000) in which the cover (303) is separated from the main body (301). As shown in Fig. 10, when the cover (303) is separated from the main body (301), the connecting member (321) can be separated from the opening / closing device (313) of the cooling module (311). In the state (1000) in which the cover (303) is separated from the main body (301), the opening / closing device (313) can shield the upper side of the cooling module (311).

[0175] Fig. 11 is a drawing showing a state (1100) in which a cover (303) is coupled to a main body (301). As shown in Fig. 11, when the cover (303) is coupled to the main body (301), a connecting member (321) can come into contact with an opening / closing device (313) of a cooling module (311). When the cover (303) is coupled to the main body (301), the connecting member (321) can push the opening / closing device (313) downward. The opening / closing device (313) can open the upper side of the cooling module (311) according to the force transmitted by the connecting member (321) (or the cover (303)).

[0176] As shown in the examples in FIGS. 10 and 11, when the cover (303) is coupled to the main body (301), the cooling module (311) of the cold storage container can be opened. For example, when the cover (303) is coupled to the main body (301), the opening / closing device (313) can open the cooling module (311). Since the cooling module (311) is opened only when the cover (303) is coupled to the main body (301), the refrigerant within the cooling module (311) can be maintained at a low temperature for a long period of time.

[0177] The opening / closing device (313) illustrated in FIGS. 10 and 11 is an example of various embodiments. FIGS. 10 and 11 are examples of a structure in which the cover (303) (or connecting member (321)) applies mechanical force to the opening / closing device (313) when the cover (303) is coupled to the main body (301). The opening / closing device for opening or closing the cooling module (311) depending on whether the cover (303) is coupled is not limited to the embodiments illustrated in FIGS. 10 and 11.

[0178] For example, the cold container may include a sensor to identify whether the cover (303) is engaged. The cold container may control the operation of the opening / closing device (313) depending on whether the cover (303) is engaged. For example, the opening / closing device (313) may include a motor that operates by electric power and a shielding wall that moves according to the operation of the motor. The cold container may supply electric power to the opening / closing device (313) depending on whether the cover (303) is engaged.

[0179]

[0180] Fig. 12 is a drawing showing a connecting member (321) in a first state according to various embodiments. Fig. 13 is a drawing showing a connecting member (321) in a second state according to various embodiments.

[0181] Referring to FIGS. 12 and 13, the connecting member (321) according to various embodiments may include a third conductive plate (323) connected to the first conductive plate (331) and the second conductive plate (315). For example, the third conductive plate (323) may be brought into contact with and / or connected to the first conductive plate (331) and the second conductive plate (315) depending on the operation of the rotating member (325).

[0182] For example, the connecting member (321) may be connected to a third conductive plate (323) and may include a rotating member (325) that rotates the third conductive plate (323). For example, the connecting member (321) may include a battery for supplying power to the rotating member (325).

[0183] For example, the cold storage container can control the operating state of the connecting member (321) or the rotating member (325). For example, the control module (or processor) can control the connecting member (321) (or the rotating member (325)) to a first state or a second state. The control module (or processor) can control the power supply from the battery to the rotating member (325).

[0184] For example, the cold storage container can control the operating state of the connecting member (321) or the connecting member (321) while the cover is connected to the main body. For example, the cold storage container can control the operating state of the connecting member (321) to a first state or a second state while the cover is connected to the main body.

[0185] For example, the cold storage container can control the connecting member (321) to shield the cooling module (311) while the cover is connected to the main body. For example, the cold storage container can control the connecting member (321) to a first state so that the connecting member (321) shields the cooling module (311).

[0186] As shown in Fig. 12, the cooling container can control the connecting member (321) to a first state. In the first state, the third conductive plate (323) can shield the upper side of the cooling module (311). As shown in Fig. 12, the third conductive plate (323) can be connected to the first conductive plate (331) and spaced apart from the second conductive plate (315).

[0187] For example, as shown in FIG. 10, the upper side of the cooling module (311) can be opened by an opening / closing device (313). The connecting member (321) or the third conductive plate (323) can shield the upper side of the opened cooling module (311).

[0188] For example, the first state may represent a state in which the third conductive plate (323) is connected to the first conductive plate (331) and spaced apart from the second conductive plate (315). For example, the first state may represent a state in which the third conductive plate (323) shields the upper side of the cooling module (311). In the first state, the third conductive plate (323) may shield the upper side of the cooling module (311).

[0189] As shown in Fig. 13, the cooling container can control the connecting member (321) to a second state. In the second state, the third conductive plate (323) can be connected to the first conductive plate (331) and the second conductive plate (315).

[0190] For example, the second state may represent a state in which the third conductive plate (323) is connected to the first conductive plate (331) and the second conductive plate (315). In the second state, the first conductive plate (331), the second conductive plate (315), and the third conductive plate (323) may exchange heat. The first conductive plate (331) may be positioned to penetrate the refrigerant. The first conductive plate (331) may be cooled by the refrigerant and may have a lower temperature than the second conductive plate (315) and / or the third conductive plate (323). In the second state, the third conductive plate (323) may be cooled by the first conductive plate (331). The third conductive plate (323) cooled by the first conductive plate (331) may cool the storage space.

[0191] Referring to FIGS. 12 and 13, the cold storage container can control the operating state of the connecting member (321) by controlling the rotating member (325). For example, the cold storage container can control the connecting member (321) to the first state by controlling the rotating member (325) as shown in FIG. 12.

[0192] For example, the cold storage container can control the connecting member (321) to the second state by controlling the rotating member (325) as shown in Fig. 13. As shown in Fig. 13, the cold storage container can control the connecting member (321) to the second state by rotating the rotating member (325) in the right direction (or counterclockwise).

[0193] In FIGS. 12 and 13, an example of a cold storage container that controls the connection between the first conductive plate (331) and the second conductive plate (315) using a rotating member (325) and a third conductive plate (323) is illustrated, but is not limited thereto. In order to control the connection between the first conductive plate (331) and the second conductive plate (315), the cold storage container may include various known devices.

[0194] For example, the connecting member (321) can control the connection between the first conductive plate (331) and the second conductive plate (315) depending on the temperature of the storage space. For example, the connecting member (321) can include a shape memory alloy. A shape memory alloy refers to a material whose shape is deformed and / or restored depending on the temperature. For example, the connecting member (321) can include a micro actuator using a shape memory alloy.

[0195] For example, the cold storage container can control the connecting member (321) (or the rotating member (325)) so that the temperature of the storage space becomes lower than the target temperature. For example, when the target temperature is -10°C, if the temperature of the storage space becomes higher than -10°C, the cold storage container can control the connecting member (321) in the first state to become a second state. For example, when the target temperature is -10°C, if the temperature of the storage space becomes higher than -10°C, the cold storage container can control the connecting member (321) so that the first conductive plate (331) becomes connected to the second conductive plate (315).

[0196] For example, the first state may represent an initial state, an idle state, or a rest state of the connecting member (321).

[0197] For example, the cold storage container can control the connecting member (321) based on the temperature of the storage space being within a target temperature and a threshold value (or set range). For example, if the target temperature is -10°C and the threshold value is -1°C, when the temperature of the storage space is above -9°C, the cold storage container can control the connecting member (321) to the second state until the temperature of the storage space is below -11°C.

[0198] For example, if the target temperature is -10°C and the threshold is -1°C, the cold storage container can control the connecting member (321) so that the temperature of the storage space is -11°C or higher and -9°C or lower.

[0199] The above-described operation of the cold storage container controlling the connecting member (321) is exemplary and is not limited to the above-described example, and the cold storage container can control the connecting member (321) in various ways.

[0200] For example, a refrigerant may contain a substance with a freezing point lower than the target temperature. A cold storage container may be a device designed to maintain the temperature of a stored item at the target temperature. The refrigerant may contain a phase change material (or PCM). The heat absorbed during the phase transition of the refrigerant can be utilized to cool the temperature inside the cold storage container.

[0201] According to one embodiment, the insulated container can utilize a refrigerant containing a substance having a freezing point lower than the target temperature, since the refrigerant is located within the insulated cooling module (311). For example, if the target temperature is -10°C, the insulated container can maintain the temperature of the storage space at the target temperature using a refrigerant (or PCM, phase change material) having a freezing point of -20°C.

[0202] The cold storage container can maintain the temperature of the storage space at a target temperature by controlling the state of the connecting member (321) to a first state or a second state. The cold storage container can maintain the temperature of the storage space at a target temperature even if the freezing point of the refrigerant is lower than the target temperature. The cold storage container can prevent the temperature of the storage space from being overcooled by controlling the state of the connecting member (321) to the first state or the second state. Since the freezing point of the refrigerant is lower than the target temperature, the time for which the cold storage container can maintain the temperature of the storage space at the target temperature can be extended.

[0203] In the above examples, the target temperature and the freezing point of the refrigerant are exemplary and are not limited to the above examples. For example, the refrigerant may include a substance with a freezing point lower than the target temperature (e.g., 10°C, 20°C, 30°C, etc.). The type of refrigerant may be determined based on the target temperature and the retention time required to maintain the storage space at the target temperature. Depending on the target temperature and / or retention time, a substance to be used as the refrigerant may be selected from among a plurality of substances having different freezing points.

[0204] According to one embodiment, a cold storage container can identify the temperature of a storage space at set intervals (e.g., every 30 minutes, every hour, etc.). For example, the cold storage container can identify the temperature of the storage space using a sensor.

[0205] For example, the cold storage container can determine whether to control (or operate) the connecting member (321) and the control time (e.g., the time to maintain the connecting member (321) in the second state) based on the identified temperature and the target temperature. For example, the cold storage container can control the connecting member (321) in the second state when the identified temperature is higher than the target temperature.

[0206] For example, the cooling container can control the connecting member (321) when the identified temperature falls within a set range. For example, the set range can be a temperature range set based on a target temperature (e.g., within 2°C of the target temperature, (target temperature) - 1°C or more, (target temperature) + 1°C or less).

[0207] For example, the cold container can determine the control time of the connecting member (321) based on the identified temperature and the target temperature. The cold container can determine the control time based on the size of the difference between the target temperature and the identified temperature. For example, if the difference between the target temperature and the identified temperature is large, the cold container can determine a longer control time. For example, when the target temperature is -10°C and the temperature of the storage space (or the identified temperature) is -11°C, the cold container can maintain the connecting member (321) in the second state longer than when the target temperature is -10°C and the temperature of the storage space is -10.5°C.

[0208] For example, the coolant container can identify the temperature of the coolant space. For example, the cooling module (311) may include a sensor for identifying the temperature of the coolant space. The coolant container can identify the temperature of the coolant space using the sensor installed in the coolant space.

[0209] For example, the insulated container can determine the expected time it will take to maintain the storage space at the target temperature based on the temperature of the refrigerant space, the temperature of the storage space, and the target temperature. For example, if the temperature of the refrigerant space is -20°C, the temperature of the storage space is -11°C, and the target temperature is -10°C, the insulated container can determine the expected time as 72 hours.

[0210] The description of the above-described operation of the cold storage container for determining whether to control the connecting member (321) and the control time and the operation of determining the expected time is exemplary and is not limited to the above-described example.

[0211] For example, the cooling module (311) may include a vent (317) that allows gas to flow to the outside of the main body. For example, the vent (317) may include a material that allows gas to flow but blocks liquid flow. When air expands and / or contracts inside the cooling module (311) due to temperature changes and / or phase changes of the refrigerant, gas may be introduced from the outside or discharged to the outside through the vent (317).

[0212] The refrigerant may include a phase change material (PCM) that absorbs or releases energy (or heat) when changing phases. The refrigerant (or phase change material) may undergo a change in volume when changing phases from liquid to solid or from solid to liquid. When the volume of the refrigerant changes, external air may be introduced through the vent (317), or air may be discharged to the outside. When the volume of the refrigerant changes, the external and gaseous matter may flow, thereby preventing deformation of the second conductive plate (315).

[0213]

[0214] FIG. 14, FIG. 15 and FIG. 16 are drawings showing a second conductive plate (315) according to various embodiments.

[0215] In FIGS. 14, 15, and 16, A may represent the other side, and B may represent one side. For example, the B (or one side) direction (or the 12 o'clock direction in FIGS. 14, 15, and 16) may represent the direction in which the second conductive plate (315) contacts the connecting member (321) and / or the third conductive plate (323). For example, the B (or one side) direction may represent the upper side of the cooling module (311) or the direction in which the cooling module (311) is opened.

[0216] For example, A (or the other side) may represent the direction (or the 6 o'clock direction in FIGS. 14, 15 and 16) opposite to the direction of B (or the other side).

[0217] Referring to FIGS. 14, 15, and 16, the second conductive plate (315) according to one embodiment may have an area in contact with the refrigerant on one side that is different from an area in contact with the refrigerant on the other side. For example, the area in contact with the refrigerant on one side of the second conductive plate (315) may be less than or equal to the area in contact with the refrigerant on the other side. For example, the area in contact with the refrigerant of the second conductive plate (315) may increase from one side to the other side.

[0218] As shown in the above-described FIGS. 10, 11, 12, and 13, the upper side (or one side) of the cooling module (311) can be opened. The refrigerant can absorb heat through the open upper side. The refrigerant can absorb heat from the second conductive plate (315) formed by penetrating the refrigerant. Therefore, when the area of ​​the conductive plate penetrating the refrigerant is the same in one direction and the other direction, the temperature of the refrigerant can rise from the upper side (or one side).

[0219] According to one embodiment, since the area of ​​the second conductive plate (315) that comes into contact with the refrigerant on one side is different from the area of ​​the second conductive plate (315) that comes into contact with the refrigerant on the other side, the temperature of the entire refrigerant can be maintained more evenly. For example, the refrigerant on one side can exchange heat through the open top on the one side and through the second conductive plate (315). The refrigerant on the other side can exchange heat through the second conductive plate (315). Since the area of ​​the second conductive plate (315) that comes into contact with the refrigerant on the other side is large, the refrigerants on the one side and the other side can maintain more even temperatures.

[0220] Referring to FIG. 14, a second conductive plate (315) according to one embodiment may include a central conductive plate formed by extending from one side to the other side. The second conductive plate (315) may include a plurality of transverse conductive plates formed by extending in a direction perpendicular to the one side to the other side of the central conductive plate. The spacing between the plurality of transverse conductive plates may decrease as they go from one side to the other side.

[0221] As shown in Fig. 14, a plurality of horizontal conductive plates may be formed to extend horizontally (e.g., in the 3 o'clock-9 o'clock direction of Fig. 14) to a central conductive plate. The spacing between the plurality of horizontal conductive plates may decrease from B to A. Since the spacing between the horizontal conductive plates in the other direction (or in the A direction) is narrow, the area where the second conductive plate (315) in the other direction contacts the refrigerant may be larger than the area where the second conductive plate (315) in the one direction (or in the B direction) contacts the refrigerant. As the area where the second conductive plate (315) contacts the refrigerant increases, the amount of heat (or energy) exchanged with the refrigerant may increase.

[0222] Referring to FIGS. 15 and 16, the second conductive plate (315) according to one embodiment may have a winding structure.

[0223] Referring to FIG. 15, the second conductive plate (315) according to one embodiment may have a gap in the vertical direction (e.g., the 12 o'clock-6 o'clock direction of FIG. 15) that decreases as it moves from one side (e.g., the B direction) to the other side (e.g., the A direction).

[0224] Referring to FIG. 16, the second conductive plate (315) according to one embodiment may have a length that increases from one side to the other in the left-right direction (e.g., the 3 o'clock-9 o'clock direction in FIG. 16). For example, the left-right direction may represent a direction perpendicular to the direction from one side to the other.

[0225] Referring to FIGS. 15 and 16, the second conductive plate (315) according to one embodiment may have a length in the left-right direction increasing and a gap in the up-down direction decreasing as it moves from one side to the other.

[0226] In FIGS. 15 and 16, the horizontal length of the second conductive plate (315) in the other direction (or A direction) is long, or the vertical gap is narrow. In FIGS. 15 and 16, the area of ​​the second conductive plate (315) in the other direction that contacts the refrigerant may be larger than the area of ​​the second conductive plate (315) in the one direction (or B direction) that contacts the refrigerant. As the area of ​​the second conductive plate (315) that contacts the refrigerant increases, the amount of heat (or energy) exchanged with the refrigerant may increase.

[0227]

[0228] FIG. 17 is a drawing showing a conductor (340) according to various embodiments.

[0229] A first conductive plate according to one embodiment may include a conductive pipe (340) containing a refrigerant therein. The conductive pipe (340) may include a cooling path through which the refrigerant cooled at one side of the cold storage container (or storage space) can move to the center of the cold storage container (or storage space), and a circulation path through which the refrigerant moved to the center of the cold storage container can move to one side of the cold storage container by capillary action.

[0230] Referring to FIG. 17, a cooling container according to various embodiments may include a conductive pipe (340). For example, the conductive pipe (340) may contain a refrigerant therein. The refrigerant contained in the conductive pipe (340) may be cooled on one side and may move to the other side. The refrigerant that has moved to the other side may then move back to the one side.

[0231] For example, the conductor (340) may include a cooling path through which cooled refrigerant moves (e.g., the first path (351) and the second path (352) of FIG. 17), and a circulation path through which heated refrigerant moves (e.g., the third path (353) of FIG. 17).

[0232] For example, the cooled refrigerant can move along the cooling path. In FIG. 17, the cooled refrigerant can move along the first path (351) and the second path (352). Since the cooled refrigerant has a high density, it can move to the lower part of the first path (351) and the second path (352) (or the other side of the conductive pipe (340)) by gravity.

[0233] For example, the refrigerant moving along the first flow path (351) and the second flow path (352) can cool the area around the first flow path (351) and the second flow path (352). The cooled refrigerant can be heated as it moves along the first flow path (351) and the second flow path (352) (to the other side of the conductor (340)).

[0234] For example, the heated refrigerant can move along the circulation path. In Fig. 17, the heated refrigerant can move along the third flow path (353). The heated refrigerant can move from the lower part of the third flow path (353) (the lower part of the first flow path (351) and the second flow path (352)) to the upper part due to the capillary phenomenon caused by gas (or fluid, liquid) expansion. The refrigerant that has moved to the upper part of the third flow path (353) can move to one side of the conductive pipe (340) and be cooled again. The refrigerant that has moved to the upper part of the third flow path (353) can move to one side of the conductive pipe (340) due to the elevation difference.

[0235] For example, the conductive pipe (340) may include a conductive member formed on its surface. For example, the conductive member may include a material with high thermal conductivity, such as aluminum or copper. By virtue of the conductive member formed on the surface of the conductive pipe (340), the heat exchange performance between the refrigerant inside the conductive pipe (340) and the outside (e.g., the cooling module (311), storage space) may be improved.

[0236]

[0237] FIG. 18 is a drawing showing a cooling module (311) and a conductive pipe (340) according to various embodiments.

[0238] Referring to FIG. 18, one side of the conductive pipe (340) may be in contact with the cooling module (311). One side of the conductive pipe (340) may be in contact with the cooling module (311), so that the refrigerant may be cooled at one side of the conductive pipe (340). For example, the temperature of the cooling module (311) may be -60°C or higher and -40°C or lower, but is not limited thereto.

[0239] Fig. 18 shows an example in which the third conductive plate (323) comes into contact with the conductive pipe (340) when the connecting member (321) is in operation. The example in which the conductive pipe (340) is cooled by the cooling module (311) is not limited to the example shown in Fig. 18.

[0240] Referring to Fig. 18, the cooled refrigerant at one side of the conductive pipe (340) can move along the first flow path (351) and the second flow path (352). The cooled refrigerant can move toward the other side of the conductive pipe (340) (or toward the center of the cold storage container). Because it is far from the cooling module (311), the temperature at the center of the cold storage container (or storage space) can be relatively higher than the temperature at the side of the cold storage container (or storage space). For example, the temperature at the side of the cold storage container (or storage space) can be about -40°C or higher and 0°C or lower, but is not limited thereto.

[0241] The cooled refrigerant can exchange heat with the air in the storage space while moving along the first flow path (351) and the second flow path (352). The air around the first flow path (351) and the second flow path (352) is cooled, and the refrigerant can absorb heat.

[0242] The refrigerant that has absorbed heat (or been heated) can move along the third passage (353). The heated refrigerant can move from the lower part of the third passage (353) to the upper part of the third passage (353) due to capillary action. The refrigerant that has moved to the upper part of the third passage (353) can move toward one side of the conductive pipe (340) (or toward the cooling module (311)) due to the difference in elevation. The refrigerant that has moved to one side of the conductive pipe (340) can be cooled again by the cooling module (311).

[0243] As described above, the refrigerant inside the conductive pipe (340) can cool the inside of the cold storage container by moving along the cooling path and the circulation path. The refrigerant can circulate inside the conductive pipe (340) due to the density difference caused by temperature changes and the capillary phenomenon.

[0244] The description of the conductor (340) in the above Fig. 18 can be substantially equally applied to the cold storage containers of Figs. 1 to 7 or the cold storage containers of Figs. 20 to 30 described below.

[0245] For example, the conductive pipe (340) illustrated in FIG. 17 can be substantially identically applied to the cover of the cold storage container illustrated in FIG. 21. For example, the conductive pipe (340) can be formed such that one side of the conductive pipe (340) is positioned below the discharge port, and the other side of the conductive pipe (340) is positioned at the center of the cover.

[0246]

[0247] FIG. 19 is a drawing showing a discharge port of a cooling module (311) according to various embodiments.

[0248] Fig. 19 is a drawing showing an example in which a plate that shields a discharge port formed on one side slides depending on the degree of deformation or restoration of a shape memory alloy (319). An example of a structure in which the degree of opening of a discharge port is determined depending on the degree of deformation or restoration of a shape memory alloy (319) is not limited to the example shown in Fig. 19, and various known structures may be applied.

[0249] According to one embodiment, the opening / closing device (313) of the cooling module (311) may include a shape memory alloy (319). For example, the shape memory alloy (319) may change shape depending on temperature. The shape memory alloy (319) of the opening / closing device (313) may block the outlet of the cooling module (311) when the temperature is lower than a set temperature. The shape memory alloy (319) of the opening / closing device (313) may open the outlet of the cooling module (311) when the temperature is higher than a set temperature.

[0250] For example, the opening / closing device (313) of FIG. 19 may include a shape memory alloy (319) formed in a spring shape. When the temperature of the storage space of the cold storage container is higher than a set temperature, the opening / closing device (313) may open the cooling module (311) according to a shape change of the shape memory alloy (319). When the temperature of the storage space of the cold storage container is lower than the set temperature, the opening / closing device (313) may shield the cooling module (311) according to a shape change of the shape memory alloy (319).

[0251] For example, the degree of opening of the cooling module (311) may be determined based on the difference between the temperature of the storage space and the set temperature. For example, when the difference between the set temperature (or critical temperature) and the temperature of the storage space is large, the shape displacement of the shape memory alloy (319) may be large. For example, when the set temperature is -20°C, the degree of opening of the cooling module (311) may be greater when the temperature of the storage space is -10°C than when the temperature of the storage space is -15°C.

[0252] For example, the degree of opening of the cooling module (311) may correspond to the area in which the discharge port of the cooling module (311) is opened.

[0253] The shape of the outlet of the opening / closing device (313) and / or the cooling module (311) illustrated in FIG. 19 and the shape of the shape memory alloy (319) are exemplary and are not limited to the example illustrated in FIG. 19. For example, the shape of the outlet of the opening / closing device (313) and / or the cooling module (311) may have various shapes such as a circle, a semicircle, etc. The shape of the shape memory alloy (319) may correspond to the shape of the outlet of the opening / closing device (313) and / or the cooling module (311).

[0254] The description of the opening / closing device (313), the discharge port of the cooling module (311) and / or the shape memory alloy (319) described in the above Fig. 19 can be substantially equally applied to the cold storage containers of Figs. 1 to 7 or the cold storage containers of Figs. 20 to 30 described below.

[0255]

[0256] In the following drawings 20 to 27, a cold storage container including a cover and a body, and a cooling module inserted into the cover to cool a storage space is described.

[0257] With respect to the cold storage containers illustrated in FIGS. 20 to 30 below, content substantially identical to that described with respect to the cold storage containers of FIGS. 1 to 7 or FIGS. 8 to 16 may be omitted. Accordingly, even if content is not described with respect to the cold storage containers of FIGS. 20 to 30, content described with respect to the cold storage containers of FIGS. 1 to 7 or FIGS. 8 to 16 may be substantially identically applied to the cold storage containers of FIGS. 20 to 30.

[0258] For example, the cold storage containers illustrated in FIGS. 20 to 30 may include upper and lower portions that are substantially the same as the upper portion (e.g., the upper portion (113) of FIGS. 3, 4, and 5) and lower portion (e.g., the lower portion (111) of FIGS. 3, 4, and 5) of the cold storage containers illustrated in FIGS. 1 to 7.

[0259]

[0260] FIG. 20 is a perspective view of a cover (400) according to various embodiments.

[0261] Referring to FIG. 20, a cold storage container according to various embodiments may include a body (e.g., body (101) of FIG. 1, body (301) of FIG. 8) having an open upper surface and including a storage space therein, and a cover (400) that shields the upper surface of the body.

[0262] For example, the cover (400) may include a control module (405), an upper cover (401), and a lower cover (403).

[0263] For example, the control module may include at least one processor and a memory electrically connected to the at least one processor and storing instructions executed by the at least one processor. For example, the description of the control module (105) of FIG. 1 may be substantially identically applied to the control module (405) of FIG. 20.

[0264] With respect to the processor and memory, the description of the processor and memory described with respect to FIG. 1 may be substantially identically applied.

[0265] For example, the cover (400) may include a cooling module. For example, the cooling module may include a refrigerant space in which a refrigerant is disposed and may be inserted into the cover (400). For example, the cooling module may be inserted into the side of the lower cover (403).

[0266] For example, the cover (400) may include a circulation device. For example, the circulation device may draw in air from the storage space and discharge the cooled air by the cooling module into the storage space.

[0267] For example, the insulated container can identify the temperature of the storage space. The insulated container can control the circulation device based on the temperature of the storage space. For example, the insulated container can include at least one sensor for identifying the temperature of the storage space. The insulated container can use the at least one sensor to identify the temperature at at least one location in the storage space. For example, the insulated container can identify the temperatures of the lower surface and upper surface of the storage space. The insulated container can identify the temperature of the middle depth of the storage space.

[0268] For example, a refrigerated container can control a circulation device based on the temperature of the storage space. For example, a control module can control the operating status of the circulation device based on the temperature of the storage space. The control module can draw air from the storage space based on the temperature of the storage space. The drawn air can be cooled by a cooling module. The circulation device can discharge or exhaust the cooled air into the storage space.

[0269] For example, the cooling module may include a refrigerant disposed in a refrigerant space. The cooling module may be inserted into an insulating member. For example, the upper cover (401) and the lower cover (403) may include a space into which the cooling module is inserted. The space into which the cooling module is inserted may be formed of an insulating member. The insulating member may block and / or minimize heat exchange between the space into which the cooling module is inserted and the outside, thereby maintaining the temperature of the cooling module and / or the refrigerant.

[0270] For example, a cooler can identify the temperature of its storage space at set intervals. The cooler can then compare the identified temperature with the target temperature to control the circulator.

[0271]

[0272] FIG. 21 is a drawing showing the lower surface of a cover (400) according to various embodiments.

[0273] As shown in Fig. 21, the lower cover (403) can be positioned on the lower side of the upper cover (401). For example, when the cover (400) is coupled to the main body, the lower cover (403) can be inserted into the main body.

[0274] Referring to FIG. 21, a circulation device according to one embodiment may include a suction device and at least one discharge port (413).

[0275] For example, the suction device can suck air from the storage space through the suction port (411) formed on the lower surface of the cover (400). For example, the suction device can operate when the cover (400) is coupled to the main body. For example, the cold container can control the operation of the suction device when the cover (400) is coupled to the main body. For example, the cold container can include a sensor for identifying whether the cover (400) is coupled to the main body.

[0276] For example, the discharge port (413) is formed on the lower surface of the cover (400) and can discharge cooled air along the path formed inside the cover (400). Air sucked in through the suction device can be cooled along the path formed inside the cover (400).

[0277] For example, the flow path formed inside the cover (400) may include a first flow path and a second flow path. For example, the first flow path may refer to a flow path formed inside the lower cover (403) (or formed by a structure inside the lower cover (403)). For example, the second flow path may refer to a flow path formed on the lower side of the cooling module (or formed by a space in the center of the lower surface of the cooling module).

[0278] Referring to Fig. 21, the intake port (411) may be formed in the center of the lower surface of the lower cover (403). The discharge port (413) may be formed at the lower edge of the lower surface of the lower cover (403). The discharge port (413) formed at the lower edge of the lower cover (403) may discharge cooled air to the side of the main body. For example, the discharge port (413) may discharge cooled air to each side of the storage space.

[0279] The size, shape, number and / or position of the intake port (411) and the discharge port (413) illustrated in FIG. 21 are exemplary and are not limited to the example illustrated in FIG. 21. FIG. 22 is a drawing showing a cooling module (421) inside a cover (400) according to various embodiments.

[0280] Fig. 22 may illustrate a cross-section of a lower cover (403) according to one embodiment. Referring to Fig. 22, the lower cover (403) may include a suction device and a cooling module (421).

[0281] As shown in Fig. 22, the cooling module (421) can be inserted into both sides of the lower cover (403). The suction device can be located on the upper side of the suction port (411) located at the center of the lower surface of the lower cover (403).

[0282] Air sucked through the suction device can travel through the first flow path (431). For example, the first flow path (431) may represent a flow path that connects the suction device to the right outlet (413) (e.g., the 2 o'clock direction outlet (413) of FIG. 21) and the left outlet (413) (e.g., the 8 o'clock direction outlet (413) of FIG. 21). The first flow path (431) may be formed by a structure for supporting the inserted cooling module (421).

[0283] For example, the second flow path may represent a flow path that connects the upper discharge port (413) (e.g., the 11 o'clock discharge port (413) in FIG. 21) and the lower discharge port (413) (e.g., the 5 o'clock discharge port (413) in FIG. 21) in the suction device. The second flow path may represent a flow path that connects the upper discharge port (413) and the lower discharge port (413) through the lower space of the cooling module (421) in the suction device. The second flow path may be formed by a space formed in the lower center of the cooling module (421).

[0284]

[0285] FIG. 23 is a drawing showing a cooling module (421) according to various embodiments.

[0286] Referring to FIGS. 22 and 23, the cooling module (421) can be inserted into the cover (400). For example, the cooling module (421) can be inserted into both sides of the cover (400) (or the lower cover (403)). The cooling module (421) can be inserted into the lower cover (403) and fixed by a structure inside the lower cover (403). For example, the lower cover (403) can include a fixing device for detaching the cooling module (421).

[0287]

[0288] FIG. 24 is a drawing showing the lower surface of a cooling module (421) according to various embodiments.

[0289] FIG. 25 is a side view of a cooling module (421) according to various embodiments.

[0290] Referring to FIGS. 24 and 25, a hollow space may be formed in the center of the lower surface of the cooling module (421). For example, the hollow space formed in the center of the lower surface of the cooling module (421) may be formed with a constant width and may be formed in the longitudinal direction of the cover (400) (e.g., the 11 o'clock-5 o'clock direction of FIG. 21).

[0291] For example, air sucked in by the suction device can move through a space formed in the center of the lower surface of the cooling module (421). The air sucked in through the suction device can move to the upper discharge port (413) and the lower discharge port (413) through the space in the center of the lower surface of the cooling module (421).

[0292] For example, the second flow path (433) may be formed by a space in the center of the lower surface of the cooling module (421). Air sucked through the suction device may move to the upper discharge port (413) and the lower discharge port (413) through the second flow path (433).

[0293]

[0294] FIG. 26 and FIG. 27 are drawings showing a conductive plate (441) according to various embodiments.

[0295] Referring to FIGS. 26 and 27, a cover (400) according to one embodiment may include at least one conductive plate (441) formed to contact a cooling module (421) and a flow path formed inside the cover (400).

[0296] Fig. 26 shows a conductive plate (441) formed in the first flow path (431). The circulation device (423) may be located inside the lower cover (403). The circulation device (423) may draw in air from the storage space, move it through the first flow path (431), and discharge the air through the discharge port (413).

[0297] For example, the first flow path (431) may represent a flow path formed by a structure inside the cover (400) (or lower cover (403)). The first flow path (431) may be separated from the cooling module (421) by the structure. Air moving through the first flow path (431) may not directly contact the cooling module (421). The air moving through the first flow path (431) may be cooled by a conductive plate (441) formed to contact the cooling module (421) and the first flow path (431).

[0298] For example, the conductive plate (441) may be formed to surround the side of a structure for supporting the cooling module (421). The conductive plate (441) may be formed to contact the first flow path (431) and the cooling module (421). The conductive plate (441) may be cooled by the cooling module (421). The cooled conductive plate (441) may cool the air moving through the first flow path (431).

[0299] Fig. 27 shows a conductive plate (441) formed in a second flow path (433). The second flow path (433) may be a flow path formed by the lower central space of the cooling module (421). Air moving through the second flow path (433) may be in direct contact with the cooling module (421). To increase the cooling efficiency of the air moving through the second flow path (433), the conductive plate (441) may be formed to be in contact with the second flow path (433) and the cooling module (421).

[0300] For example, the conductive plate (441) formed in the second flow path (433) may be formed on the lower surface of the cooling module (421) or inside the cover (400). The conductive plate (441) formed in the second flow path (433) may be cooled by the cooling module (421). Air moving through the second flow path (433) may be cooled by the conductive plate (441).

[0301]

[0302] Figures 28, 29 and 30 are drawings showing air circulation in a cold storage container according to various embodiments.

[0303] Fig. 28 shows the lower cover (403) of the cover (400). Fig. 29 shows the air circulation in the AA` direction of the lower cover (403) of Fig. 28, and Fig. 30 shows the air circulation in the BB` direction of the lower cover (403) of Fig. 28.

[0304] As shown in Fig. 29, the cover (400) draws air from the center of the main body (or the center of the storage space). The air drawn into the center of the lower surface of the cover (400) can move through a passage (e.g., a first passage (431)) formed inside the cover (400). The circulation device (423) can draw air from the center of the lower surface of the cover (400) and move the air through the passage formed inside the cover (400). The air moving through the passage can be cooled by the cooling module (421) (or the conductive plate (441)).

[0305] Air moving through the flow path can be discharged through the outlet (413). Air moving through the flow path can be discharged into the storage space. Air discharged through the outlet (413) corresponding to the first flow path (431) (e.g., the 2 o'clock direction outlet (413) and the 8 o'clock direction outlet (413) of FIG. 21) can be discharged toward the side of the main body (or the side of the storage space).

[0306] As shown in Fig. 29, the cold storage container can circulate air along the first circulation path (451-1) and the second circulation path (451-2) in the AA` direction of Fig. 28. The air flowing along the first circulation path (451-1) and the second circulation path (451-2) can be cooled in a passage (e.g., the first passage (431)) inside the cover (400).

[0307] As shown in Fig. 30, the cover (400) draws air from the center of the main body (or the center of the storage space). The air drawn into the center of the lower surface of the cover (400) can move through a passage (e.g., a second passage (433)) formed inside the cover (400). The circulation device (423) can draw air from the center of the lower surface of the cover (400) and move the air through a passage formed inside the cover (400). The air moving through the passage can be cooled by the cooling module (421) (or the conductive plate (441)).

[0308] As shown in Fig. 30, the cold storage container can circulate air along the third circulation path (451-3) and the fourth circulation path (451-4) in the BB` direction of Fig. 28. The air flowing along the third circulation path (451-3) and the fourth circulation path (451-4) can be cooled in a passage (e.g., the second passage (433)) inside the cover (400).

[0309] Air moving through the flow path can be discharged through the outlet (413). Air moving through the flow path can be discharged into the storage space. Air discharged through the outlet (413) corresponding to the second flow path (433) (e.g., the 11 o'clock direction outlet (413) and the 5 o'clock direction outlet (413) of FIG. 21) can be discharged toward the side of the main body (or the side of the storage space).

[0310] For example, the cold storage container can control the circulation device (423) so that the temperature of the storage space becomes lower than the target temperature. For example, if the target temperature is -10°C, and the temperature of the storage space becomes higher than -10°C, the cold storage container can operate the circulation device (423). For example, if the target temperature is -10°C, and the temperature of the storage space becomes higher than -10°C, the cold storage container can control the circulation device (423) so that it draws in air from the storage space and discharges the cooled air into the storage space.

[0311] For example, the cold storage container can control the circulation device (423) based on the temperature of the storage space being within a threshold (or set range) from the target temperature. For example, if the target temperature is -10°C and the threshold is -1°C, when the temperature of the storage space is above -9°C, the cold storage container can operate the circulation device (423) until the temperature of the storage space is below -11°C.

[0312] For example, if the target temperature is -10°C and the threshold is -1°C, the cold storage container can operate the circulation device (423) so that the temperature of the storage space is -11°C or higher and -9°C or lower.

[0313] The above-described operation of the refrigerated container controlling the circulation device (423) is exemplary and is not limited to the above-described example, and the refrigerated container can control the circulation device (423) in various ways.

[0314] For example, a refrigerant may contain a substance with a freezing point lower than the target temperature. A cold storage container may be a device designed to maintain the temperature of a stored item at the target temperature. The refrigerant may contain a phase change material (or PCM). The heat absorbed during the phase transition of the refrigerant can be utilized to cool the temperature inside the cold storage container.

[0315] According to one embodiment, the insulated container can utilize a refrigerant containing a substance having a freezing point lower than the target temperature, since the refrigerant is located within an insulated space (e.g., within the cover (400)). For example, if the target temperature is -10°C, the insulated container can maintain the temperature of the storage space at the target temperature by utilizing a refrigerant (or PCM, phase change material) having a freezing point of -20°C.

[0316] The cold storage container can maintain the temperature of the storage space at a target temperature by controlling the operation of the circulation device (423). The cold storage container can maintain the temperature of the storage space at the target temperature even if the freezing point of the refrigerant is lower than the target temperature. The cold storage container can prevent the temperature of the storage space from being overcooled by controlling the operation of the circulation device (423). Since the freezing point of the refrigerant is lower than the target temperature, the time for which the cold storage container can maintain the temperature of the storage space at the target temperature can be extended.

[0317] In the above examples, the target temperature and the freezing point of the refrigerant are exemplary and are not limited to the above examples. For example, the refrigerant may include a substance with a freezing point lower than the target temperature (e.g., 10°C, 20°C, 30°C, etc.). The type of refrigerant may be determined based on the target temperature and the retention time required to maintain the storage space at the target temperature. Depending on the target temperature and / or retention time, a substance to be used as the refrigerant may be selected from among a plurality of substances having different freezing points.

[0318] According to one embodiment, a cold storage container can identify the temperature of a storage space at set intervals (e.g., every 30 minutes, every hour, etc.). For example, the cold storage container can identify the temperature of the storage space using a sensor.

[0319] For example, the cold container can determine whether to control (or operate) the circulation device (423) and the control time (e.g., the time to operate the circulation device (423)) based on the identified temperature and the target temperature. For example, the cold container can operate the circulation device (423) when the identified temperature is higher than the target temperature.

[0320] For example, the cooling container may operate the circulation device (423) when the identified temperature falls within a set range. For example, the set range may be a temperature range set based on a target temperature (e.g., within 2°C of the target temperature, (target temperature) - 1°C or more, (target temperature) + 1°C or less).

[0321] For example, the cold container can determine the control time of the circulation device (423) based on the identified temperature and the target temperature. The cold container can determine the control time based on the size of the difference between the target temperature and the identified temperature. For example, if the difference between the target temperature and the identified temperature is large, the cold container can determine a longer control time. For example, the cold container can operate the circulation device (423) longer when the target temperature is -10°C and the temperature of the storage space (or the identified temperature) is -11°C than when the target temperature is -10°C and the temperature of the storage space is -10.5°C.

[0322] For example, the cold container can identify the temperature of the cooling module (421). For example, the cold container can include a sensor for identifying the temperature of the cooling module (421). The cold container can identify the temperature of the cooling module (421) using the installed sensor.

[0323] For example, the cold storage container can determine an expected time for which the storage space can be maintained at a target temperature based on the temperature of the cooling module (421), the temperature of the storage space, and the target temperature. For example, if the temperature of the cooling module (421) is -20°C, the temperature of the storage space is -11°C, and the target temperature is -10°C, the cold storage container can determine an expected time as 72 hours.

[0324] The description of the above-described operation of the cooling container for determining whether to control the circulation device (423) and the control time and the operation of determining the expected time is exemplary and is not limited to the above-described example.
