Description

Technical Field

[0001] This application relates to the field of intelligent insulation equipment technology, and more specifically, to an intelligent control insulation box and its control method. Background Technology

[0002] Current insulated boxes on the market have significant shortcomings in terms of refrigeration performance and intelligent control. Traditional insulated boxes mainly adopt a single refrigeration source design, which has several technical defects: First, because only a single refrigeration unit is used, the cooling of different parts of the box is uneven, with a significant temperature difference between the top and the sides, making precise temperature control impossible; second, existing products lack intelligent temperature regulation strategies, maintaining full power operation even when approaching the target temperature, which wastes energy and easily leads to temperature overshoot; third, conventional insulated boxes do not have temperature prediction and scheduled cooling functions, preventing users from planning cooling solutions in advance according to their needs.

[0003] In terms of cooling efficiency, traditional semiconductor-controlled coolers suffer from slow response times. When the ambient temperature is high, a single cooling chip system takes a considerable amount of time to lower the internal temperature to the required range, severely impacting the user experience. Furthermore, existing products generally lack effective utilization of phase change materials, making it impossible to maintain a stable temperature environment during power outages. While passive cooling solutions can address the power outage insulation problem, they require users to pre-freeze ice packs, making the process cumbersome and unable to meet immediate cooling needs.

[0004] Regarding control systems, existing insulated boxes mostly employ simple on / off temperature control, which cannot dynamically adjust refrigeration power based on actual temperature changes. This control method easily leads to large temperature fluctuations and high energy consumption. Furthermore, existing products lack comprehensive consideration of ambient temperature and the thermodynamic characteristics of the enclosure, making it difficult to achieve precise temperature maintenance and energy-efficient operation.

[0005] There is currently no effective technical solution to the above problems. Summary of the Invention

[0028] For ease of understanding, some key terms in this embodiment are explained below. The outer shell 1 of this embodiment refers to the outermost structure of the intelligent control insulated box. It is typically made of a material with certain strength and heat insulation properties, used to protect internal components and provide overall structural support. Its internal space accommodates the insulated box body 2 and the insulated box lid 3. The insulated box body 2 of this embodiment refers to the main storage space located inside the outer shell 1. It has good heat insulation properties and is used to store items that need to maintain a specific temperature. The insulated box lid 3 of this embodiment refers to the component used to cover the top of the insulated box body 2. It works with the insulated box body 2 to form a relatively sealed space, jointly achieving the heat insulation function. The first radiator 4 of this embodiment refers to a heat exchange device filled with a phase change cold storage medium (preferably water). This medium can absorb heat and store cold energy. In this embodiment, the first radiator 4 is located on the bottom surface of the insulated box lid 3, mainly responsible for heat exchange in the top area of ​​the insulated box body 2, thereby working with the second radiator 5 to cool the insulated box body 2 from all directions. The second radiator 5 in this embodiment is similar to the first radiator 4, and is also a heat exchange device. It is filled with a phase change cold storage medium. In this embodiment, the second radiator 5 wraps around the sides and bottom of the insulated box 2, and is mainly responsible for cooling the area of ​​the insulated box 2 through the sides and bottom of the insulated box 2. The first cooling component 6 in this embodiment refers to a device for cooling the first radiator 4. It lowers the temperature of the first radiator 4 and stores cold energy through refrigeration, so that the first radiator 4 can continuously cool the bottom surface of the insulated box cover 3 even when the first cooling component 6 is not working. The second cooling component 7 in this embodiment refers to a device for cooling the second radiator 5. It lowers the temperature of the second radiator 5 and stores cold energy through refrigeration, so that the second radiator 5 can continuously cool the insulated box 2 even when the second cooling component 7 is not working. The first temperature acquisition component 8 in this embodiment refers to a sensor and related circuitry used for real-time monitoring and acquisition of temperature information. In this embodiment, it is used to acquire the first temperature information corresponding to the first radiator 4 and the second temperature information corresponding to the second radiator 5 to provide temperature feedback data to the controller 9. In this embodiment, controller 9 refers to the core control unit of the intelligent control insulation box, typically composed of a microprocessor, memory, and input / output interfaces. It receives temperature information and external commands from the temperature acquisition component and controls the cooling components according to preset control logic and strategies to maintain the target temperature. The cooling radiator command in this embodiment refers to the command sent by the user or external system to controller 9 to initiate the cooling process of the radiator. This command includes a first preset target temperature, indicating the target temperature value that the radiator needs to achieve. The first preset target temperature in this embodiment refers to the target temperature value set in the cooling radiator command; the first cooling component 6 and the second cooling component 7 will strive to ensure that the temperatures of both the first radiator 4 and the second radiator 5 reach or fall below this value.The first preset cooling power in this embodiment refers to the higher cooling power used by the cooling component in the initial stage of the cooling process or when rapid cooling is required. The second preset cooling power in this embodiment refers to the lower cooling power used by the cooling component in the later stage of the cooling process or when approaching the target temperature, in order to refine temperature control and save energy. The first preset threshold in this embodiment refers to a threshold used to determine the difference between the current temperature and the target temperature. When the temperature difference is less than this threshold, the system will switch the cooling power. The preset time window in this embodiment refers to the time period used to calculate the rate of temperature change. The second preset threshold in this embodiment refers to a threshold used to determine whether the rate of temperature change is stable. When the rate of temperature change is less than this threshold, it indicates that the temperature has stabilized.

[0029] This application proposes an intelligent control insulated box, aiming to solve the problems of low cooling efficiency and uneven temperature distribution in traditional insulated boxes, and to achieve intelligent cooling control. The intelligent control insulated box includes an outer shell 1, an insulated box body 2, an insulated box lid 3, a first cold radiator 4, a second cold radiator 5, a first cooling component 6, a second cooling component 7, a first temperature acquisition component 8, and a controller 9. The outer shell 1 is the external structure of the insulated box, and the insulated box body 2 and the insulated box lid 3 are housed inside. The outer shell 1 can be made of various materials and structures, such as plastic, metal, or composite materials, and filled with insulating materials such as polyurethane foam to provide good insulation performance. The insulated box body 2 and the insulated box lid 3 create a relatively sealed space inside the insulated box for storing items requiring insulation. The first radiator 4 is located on the bottom surface of the insulated box cover 3, and the second radiator 5 surrounds the sides and bottom of the insulated box body 2. This radiator layout allows the cooling area to cover the key parts of the intelligent control insulated box, and this application can effectively avoid the uneven temperature distribution problem caused by traditional single refrigeration sources through this partitioned cooling design. The first cooling component 6 is used to cool the first radiator 4, and the second cooling component 7 is used to cool the second radiator 5. The cooling components can adopt various refrigeration technologies. For example, they can use semiconductor refrigeration chips (such as Peltier effect refrigeration chips), whose cold end contacts the radiator and whose hot end dissipates heat through a heat sink. Alternatively, they can use a small compressor refrigeration system, which removes heat through the circulation, evaporation, and condensation of the refrigerant. By setting two independent cooling components, independent cooling control of different areas of the insulated box cover 3 and the insulated box body 2 can be achieved, thereby improving the overall refrigeration efficiency and the flexibility of temperature control. The first temperature acquisition component 8 is used to acquire the first temperature information corresponding to the first radiator 4 and the second temperature information corresponding to the second radiator 5. The temperature acquisition component typically consists of temperature sensors (such as thermistors, thermocouples, or PT100 sensors) and signal processing circuitry. These sensors can be installed on the surface or inside the first radiator 4 and the second radiator 5, respectively, to monitor their temperature changes in real time. The acquired temperature information is transmitted to the controller 9 as the basis for subsequent cooling strategy execution. The controller 9 executes the first cooling strategy upon receiving a cooling radiator command, which includes a first preset target temperature. The controller 9 is the core of the entire intelligent control insulation box. It receives cooling commands from the user or a preset program and, based on the first preset target temperature included in the command, initiates and executes the corresponding cooling strategy. For example, the user can send a cooling command through the operation panel on the insulation box or through a smartphone application, setting the target temperature the radiator is expected to reach. The first cooling strategy includes two main steps: A1 and A2.Specifically, step A1 is executed at the initial stage of the cooling process. To achieve rapid cooling, the controller 9 instructs the two cooling components to operate at a higher first preset cooling power. For example, if the cooling component is a semiconductor cooling chip, the first preset cooling power may correspond to its maximum or near-maximum operating current to provide maximum cooling capacity. This high-power operation mode can quickly reduce the initial temperature of the radiator and shorten the time required to reach the target temperature. Step A2 is executed at the later stage of the cooling process (when the difference between the first temperature information and the first preset target temperature or the difference between the second temperature information and the first preset target temperature is less than the first preset threshold), controlling both the first cooling component 6 and the second cooling component 7 to operate at a second preset cooling power until both the first temperature information and the second temperature information are less than or equal to the first preset target temperature and the rate of change of the first temperature information and the rate of change of the second temperature information within the preset time window are both less than or equal to the second preset threshold. Step A2 is equivalent to the controller 9 switching the power of the cooling components to a lower second preset cooling power when the temperature of the radiator approaches the target temperature, in order to avoid overcooling and achieve more precise temperature control. For example, the second preset cooling power may correspond to the lower operating current or duty cycle of the semiconductor cooling chip. This low-power operating mode can finely adjust the temperature, smoothly approaching the first preset target temperature. At the same time, the system continuously monitors the temperature of the two radiators until they both reach or fall below the first preset target temperature, and within a preset time window, their temperature change rates are very small (less than the second preset threshold). This indicates that the radiator temperature has stabilized at the target value and the ice pack has accumulated sufficient cooling.

[0030] The following is a more specific example to illustrate the above technical solution in greater detail: Suppose user A needs to rapidly cool items inside a smart-controlled insulated box from an ambient temperature of 25°C to -5°C, and wants the ice packs to store sufficient cold. User A inputs a cooling command for the ice packs through the control panel of the insulated box, setting the first preset target temperature to -5°C. Upon receiving this command, controller 9 immediately activates the first cooling strategy. In step A1, controller 9 instructs both the first cooling component 6 and the second cooling component 7 to operate at the first preset cooling power. For example, if both the first cooling component 6 and the second cooling component 7 use semiconductor refrigeration chips, controller 9 will make them operate at full speed with a 100% duty cycle. At this time, the first ice pack 4 and the second ice pack 5 begin to cool rapidly, and their internal phase change cold storage medium also begins to store cold energy. The first temperature acquisition component 8 monitors the temperature of the first ice pack 4 and the second ice pack 5 in real time and feeds back the first and second temperature information to controller 9. As cooling proceeds, the temperature of the first ice pack 4 and the second ice pack 5 gradually decreases. When the difference between the first temperature information and the first preset target temperature (-5°C), or the difference between the second temperature information and the first preset target temperature (-5°C), is less than the first preset threshold (e.g., 3°C, i.e., when either radiator temperature reaches -2°C), the controller 9 will proceed to step A2. In step A2, the controller 9 will instruct the first cooling component 6 and the second cooling component 7 to operate at the second preset cooling power. For example, the duty cycle of the cooling components may be adjusted to 50% at this time to reduce the cooling intensity and prevent temperature overshoot. The controller 9 will continuously monitor the first and second temperature information. When the temperatures of both radiators are less than or equal to -5°C, and within a preset time window (e.g., 5 minutes), the rate of change of the first temperature information and the rate of change of the second temperature information are both less than or equal to the second preset threshold (e.g., 0.1°C / minute), this indicates that the temperatures of the two radiators have stabilized at the target values, and the ice radiators have accumulated sufficient cold. At this time, the controller 9 can issue a prompt indicating that cooling is complete, and can switch to the heat preservation mode or stop cooling according to subsequent instructions.

[0031] As can be seen from the above examples, the intelligent control insulated box of this application achieves rapid cooling and precise temperature control through independent control of dual radiators and dual cooling components, combined with an intelligent cooling strategy. Traditional insulated boxes typically use a single cooling element, which has low cooling efficiency, making it difficult to lower the internal temperature to a low level quickly, and resulting in uneven temperature distribution. This application, however, significantly improves cooling capacity by dividing the cooling area into the insulated box cover 3 and the sides and bottom of the insulated box body 2, and configuring independent cooling components for each. In the initial cooling stage, a high-power operating mode is used to rapidly reduce the overall temperature, which is more efficient than the slow cooling process of a traditional single cooling source. When the temperature approaches the target value, it switches to a low-power operating mode, and combined with the judgment of the temperature change rate, it can achieve more precise temperature control, avoiding the problems of overcooling or large temperature fluctuations that may occur in traditional solutions. This regional and phased intelligent cooling strategy not only improves refrigeration efficiency and ensures uniform temperature distribution, but also enables sufficient cold storage of ice packs, providing ample cold energy reserves for subsequent insulation or transportation. This solves the problems of low refrigeration efficiency, uneven temperature distribution, and inability to achieve intelligent cooling control in traditional insulated boxes.

[0032] In some preferred embodiments, step A2 includes: A21. When the difference between the first temperature information and the first preset target temperature or the difference between the second temperature information and the first preset target temperature is less than the first preset threshold, the first cooling component 6 and the second cooling component 7 are controlled to operate at the second preset cooling power. A22. When the first temperature information is greater than the first preset target temperature, the second temperature information is greater than the first preset target temperature, the rate of change of the first temperature information within a preset time window is greater than the second preset threshold, or the rate of change of the second temperature information within a preset time window is greater than the second preset threshold, the cooling power of the first cooling component 6 and / or the second cooling component 7 is adjusted according to the deviation between the first temperature information and the second temperature information. A23. When both the first temperature information and the second temperature information are less than or equal to the first preset target temperature and both the rate of change of the first temperature information and the rate of change of the second temperature information within the preset time window are less than or equal to the second preset threshold, the first cooling component 6 and the second cooling component 7 shall be controlled to stop operating.

[0033] In step A21, if the difference between the first temperature information and the first preset target temperature, or the difference between the second temperature information and the first preset target temperature, is less than a first preset threshold, it indicates that the temperature of the first radiator 4 and / or the second radiator 5 is very close to the preset target temperature. The first preset threshold is a small temperature difference, such as 1℃, 0.5℃, or 0.2℃, used to define the conditions for the temperature to enter the fine control range. When the temperature difference between any radiator and the first preset target temperature is less than this threshold, it indicates that the system has entered the vicinity of the target temperature and needs to switch from the rapid cooling mode to the fine temperature control mode. At this time, the first cooling component 6 and the second cooling component 7 are both controlled to operate at a second preset cooling power. The second preset cooling power is a power value lower than the first preset cooling power, in order to perform stable cooling when the temperature of the first or second radiator approaches the first preset target temperature. For example, the first preset cooling power can be full power operation with a 100% duty cycle, while the second preset cooling power can be lower power operation with a 50% or 30% duty cycle, or it can be achieved by reducing the driving voltage or current of the cooling components. This measure aims to avoid temperature overshoot, reduce energy consumption, and provide a buffer for subsequent precise adjustments.

[0034] In step A22, "the first temperature information is greater than the first preset target temperature, and the second temperature information is greater than the first preset target temperature" indicates that during the fine control stage, the actual temperature of the first radiator 4 or the second radiator 5 is still higher than the preset target temperature, and cooling needs to continue. "The rate of change of the first temperature information within a preset time window is greater than the second preset threshold, or the rate of change of the second temperature information within a preset time window is greater than the second preset threshold" indicates that within a certain preset time period, the temperature fluctuation of the first radiator 4 or the second radiator 5 is large, and the cold storage of the first radiator 4 or the second radiator 5 has not yet reached a stable state. The preset time window can be a fixed time period, such as 1 minute, 5 minutes, or 10 minutes, used to calculate the rate of temperature change. The second preset threshold is a small rate of temperature change, such as 0.1℃ / min or 0.05℃ / min, used to determine whether the temperature is stabilizing. When the rate of temperature change exceeds this threshold, it indicates that the temperature has not yet stabilized and further adjustment is needed. At this time, the cooling power of the first cooling component 6 and / or the second cooling component 7 is adjusted according to the deviation between the first and second temperature information. Adjusting the cooling power can employ various control algorithms, such as PID control, fuzzy control, or adaptive control. Specifically, the power output of each cooling component can be dynamically adjusted based on the temperature difference between the two radiators. For example, if the temperature of the first radiator 4 (first temperature information) is higher than the temperature of the second radiator 5 (second temperature information), the power of the first cooling component 6 can be appropriately increased, while the power of the second cooling component 7 can be maintained or slightly reduced to achieve a balanced and synchronous temperature drop.

[0035] In step A23, "both the first temperature information and the second temperature information are less than or equal to the first preset target temperature" indicates that the temperatures of both radiators have reached or fallen below the preset target temperature. "The rate of change of both the first and second temperature information within the preset time window is less than or equal to the second preset threshold" indicates that the temperatures of both radiators have stabilized over a period of time, with very slow temperature changes, indicating that the radiators have sufficiently stored cold. When both conditions are met simultaneously, the system determines that the radiators have reached a state of sufficient cold storage and temperature stability. At this point, the operation of the cooling components is stopped to save energy and prevent overcooling.

[0036] Traditional insulated boxes often employ simple on / off control or fixed power operation when the temperature approaches the target value. This can easily lead to temperature overshoot, large fluctuations, and even failure to stop cooling in time, resulting in energy waste or unstable temperature control. To address this, this application refines the cooling control process by introducing more sophisticated staged control logic in step A2 of the first cooling strategy. Specifically, when the controller 9 of the intelligent insulated box receives a cooling radiator command and begins executing the first cooling strategy, it first controls both the first cooling component 6 and the second cooling component 7 to operate at a first preset cooling power to achieve rapid cooling. As cooling progresses, when the difference between the first temperature information collected by the first temperature acquisition component 8 and the first preset target temperature, or the difference between the second temperature information and the first preset target temperature, is less than the first preset threshold, the system determines that the radiator temperature is close to the target value. At this point, it switches from high-power rapid cooling mode to fine temperature control mode, controlling both the first cooling component 6 and the second cooling component 7 to operate at the second preset cooling power. Since the second preset cooling power is lower than the first preset cooling power, this step aims to slow down the cooling rate, providing a buffer for subsequent precise adjustments and avoiding temperature overshoot. During this fine temperature control phase, the controller 9 continuously monitors the first and second temperature information. If the temperature of either radiator is still higher than the first preset target temperature, or if the rate of temperature change of either radiator is still greater than the second preset threshold within the preset time window (indicating that the temperature has not yet stabilized or is still rapidly decreasing), the controller 9 will dynamically adjust the cooling power of the first cooling component 6 and / or the second cooling component 7 based on the deviation between the first and second temperature information. This dynamic adjustment mechanism can specifically respond to the temperature differences and trends of the two radiators. For example, if the temperature of the first radiator 4 is relatively high, the power of the first cooling component 6 can be appropriately increased to accelerate its cooling, thereby achieving a balanced and synchronous temperature decrease for both radiators and ensuring the consistency of ice storage. This real-time feedback-based adjustment effectively prevents temperature overshoot or oscillation, improving the stability and accuracy of temperature control. Finally, when both the first and second temperature information are less than or equal to the first preset target temperature, and the rates of change of both the first and second temperature information within the preset time window are less than or equal to the second preset threshold, the system determines that both radiators have reached a sufficient state of ice storage and the temperature is stable. At this time, the controller 9 will issue a command to stop the operation of the first cooling component 6 and the second cooling component 7. This precise shutdown condition not only ensures that the radiator achieves the expected cold storage effect, but also avoids unnecessary energy consumption, achieving a balance between energy saving and efficient control.

[0037] To address the issue that the temperature of the insulation box may rise above the target temperature after the cooling components stop operating, leading to temperature instability and reduced insulation performance, in some preferred embodiments, the first cooling strategy further includes: A3. When the first cooling component 6 stops operating and the first temperature information reaches the upper limit of the first preset range, the first cooling component 6 is controlled to operate at the second preset cooling power until the first temperature information reaches the lower limit of the first preset range; the first preset target temperature is within the first preset range. A4. When the second cooling component 7 stops operating and the second temperature information reaches the upper limit of the first preset range, control the second cooling component 7 to operate at the second preset cooling power until the second temperature information reaches the lower limit of the first preset range.

[0038] The first cooling component 6 stopping operation means that its cooling function is actively shut down or suspended. This can be achieved by cutting off its power supply, for example, through relay control, or by setting the control signal sent by the controller 9 to the first cooling component 6 to zero output, thus putting it into standby or non-working state. The upper limit of the first preset range is preferably a temperature value that is higher than the first preset target temperature by a certain allowable deviation value. When the first temperature information reaches this upper limit value, it is considered that the insulation effect of the intelligent control insulation box cannot meet the expected insulation effect. At this time, the controller 9 will trigger the corresponding cooling action (controlling the first cooling component 6 to operate at the second preset cooling power) to re-store cold on the first radiator 4 until the first temperature information reaches the lower limit value of the first preset range. That is, when the first temperature information reaches this lower limit value, the controller 9 will stop the operation of the first cooling component 6 again. The first preset target temperature is within the first preset range, meaning it is less than the upper limit and greater than the lower limit. Since the rise in the first temperature information means a decrease in the cold storage capacity of the first radiator 4, when the first temperature information rises to the upper limit of the first preset range, it is considered that the cold storage capacity of the first radiator 4 is insufficient. At this time, the first ice radiator needs to re-store cold to maintain the temperature of the top area of ​​the insulation box 2, thereby ensuring the insulation effect of the insulation box 2. The technical features of the second cooling component 7 stopping operation, the second temperature information reaching the upper limit of the first preset range, controlling the second cooling component 7 to operate at the second preset cooling power, and until the second temperature information reaches the lower limit of the first preset range are similar to the description of the first cooling component 6 and the first temperature information, but are applied to the second temperature information corresponding to the second cooling component 7 and the second radiator 5 to achieve temperature maintenance of the insulation box 2.

[0039] The solution in this application rapidly reduces and stabilizes the temperatures of the first radiator 4 and the second radiator 5 to a first preset target temperature through steps A1 and A2, and further introduces an intelligent temperature maintenance mechanism (heat preservation mechanism). When the first cooling component 6 and the second cooling component 7 stop operating, the temperatures of the first radiator 4 and the second radiator 5 will gradually rise due to the influx of ambient heat. At this time, the controller 9 continuously monitors the first and second temperature information collected by the first temperature acquisition component 8. Once the first or second temperature information reaches the upper limit of the preset first preset range, the controller 9 will correspondingly activate the corresponding cooling component (the first cooling component 6 or the second cooling component 7). These cooling components will operate at a lower second preset cooling power until the corresponding temperature information drops to the lower limit of the first preset range. After that, the cooling components stop operating again, waiting for the next temperature rise. This intermittent, low-power operation mode, combined with the condition that the first preset target temperature is greater than or equal to the upper limit of the first preset range, ensures the accuracy and effectiveness of the cooling operation, avoiding over-cooling and unnecessary energy consumption. In this way, the system can autonomously maintain the temperature of the first radiator 4 and the second radiator 5 within a narrow and stable range, thereby ensuring that the temperature inside the insulation box remains stable and effectively solving the instability problem caused by temperature rise after the cooling components stop operating.

[0040] In some preferred embodiments, the insulated box body 2 and the insulated box lid 3 are made of the same material. The intelligent insulated box also includes a second temperature acquisition component 10 and a third temperature acquisition component 11. The second temperature acquisition component 10 is used to acquire ambient temperature information, and the third temperature acquisition component 11 is used to acquire internal temperature information of the insulated box body 2. The controller 9 is also used to execute a second cooling strategy when receiving a scheduled cooling command. The scheduled cooling includes a scheduled usage time and a second preset target temperature. The second cooling strategy includes: B1. Obtain the preset heat capacity and preset thermal resistance of the insulation box body 2 and the insulation box cover 3; B2. Using a pre-trained thermodynamic model, a theoretical cooling time is generated based on preset heat capacity, preset thermal resistance, ambient temperature information, internal temperature information of the chamber, first temperature information, second temperature information, and second preset target temperature. B3. Determine the cooling start time based on the scheduled usage time, theoretical cooling time, and preset safety redundancy time; B4. When the cooling start-up time is reached at the current moment, control both the first cooling component 6 and the second cooling component 7 to operate at the third preset cooling power. B5. When the running time of the first cooling component 6 reaches the lower limit of the preset running time range, the PID controller 9 adjusts the cooling power of the first cooling component 6 and the second cooling component 7 according to the deviation between the internal temperature information of the chamber and the second preset target temperature, so that the internal temperature information of the chamber reaches the second preset target temperature; the preset running time range is within the time range covered by the theoretical cooling time. B6. When the running time of the first cooling component 6 reaches the upper limit of the preset running time range, the first temperature information and the second temperature information are both less than or equal to the first preset target temperature, and the change rate of the first temperature information and the change rate of the second temperature information within the preset time window are both less than or equal to the second preset threshold, the first cooling component 6 and the second cooling component 7 are controlled to stop running. Then, when the internal temperature information of the chamber reaches the upper limit of the second preset range, the first cooling component 6 and the second cooling component 7 are controlled to run at the fourth preset cooling power until the internal temperature information of the chamber reaches the lower limit of the second preset range. The second preset target temperature is within the second preset range, and the fourth preset cooling power is less than the third preset cooling power.

[0041] The purpose of using the same material for the insulated box body 2 and the insulated box lid 3 in this embodiment is to ensure the consistency of the overall thermal conductivity of the insulated box. This is crucial for the accurate establishment and calculation of the subsequent thermodynamic model. The material can be a material with good thermal insulation properties, such as high-density polyethylene (HDPE) or polypropylene (PP) plastics, with the interior filled with polyurethane foam or vacuum insulation panels. The second temperature acquisition component 10 is used to collect ambient temperature information. It can be a thermistor, thermocouple, or infrared temperature sensor, and is usually placed on the outside of the insulated box shell 1 to monitor the temperature changes of the environment in which the insulated box is located in real time. The third temperature acquisition component 11 is used to collect the internal temperature information of the insulated box body 2. It can be a thermistor, thermocouple, or digital temperature sensor, and is usually placed inside the insulated box body 2 to monitor the temperature of the air or stored items inside the box in real time. When controller 9 receives a scheduled cooling command, it executes the second cooling strategy. The scheduled cooling command is a command issued by the user to the system through a human-machine interface (such as a touch screen or mobile APP). This command includes the user's desired future time (scheduled usage time) and the target temperature (second preset target temperature) that should be achieved inside the insulation box 2 at that time. The second cooling strategy is a series of preset control steps designed to intelligently plan and execute the cooling process based on the user-set scheduling information.

[0042] In the second cooling strategy, step B1 aims to obtain the preset heat capacity and preset thermal resistance of the insulation box 2 and the insulation box cover 3. The preset heat capacity and preset thermal resistance are inherent thermodynamic parameters of the insulation box 2 and the insulation box cover 3, which can be measured experimentally or consulted in material handbooks. These parameters reflect the material's ability to absorb and transfer heat. Step B2 aims to generate a theoretical cooling time using a pre-trained thermodynamic model based on the preset heat capacity, preset thermal resistance, ambient temperature information, box internal temperature information, first temperature information, second temperature information, and second preset target temperature. This thermodynamic model can be a mathematical model based on the physical laws of heat transfer, or a predictive model trained using machine learning algorithms (such as neural networks or support vector machines). This model comprehensively considers the structural characteristics of the insulation box (preset heat capacity and preset thermal resistance), internal and external temperature conditions (ambient temperature information, box internal temperature information, first temperature information, and second temperature information), and the target temperature (second preset target temperature), thereby predicting the time required to cool the temperature inside the insulation box 2 from the current temperature to the preset target temperature (theoretical cooling time). Step B3 aims to determine the cooling start-up time based on the scheduled usage time, theoretical cooling duration, and preset safety redundancy duration. The cooling start-up time is the specific moment the system begins cooling. The preset safety redundancy duration is extra time reserved to cope with model errors, sudden environmental changes, or system performance fluctuations, ensuring that the internal temperature can stably reach the target before the scheduled usage time. Step B4 aims to control both the first cooling component 6 and the second cooling component 7 to operate at a third preset cooling power when the cooling start-up time is reached at the current moment. The third preset cooling power is typically the maximum or higher power of the cooling components, used to quickly reduce the internal temperature in the early stages of cooling, thereby shortening the overall cooling time. Step B5 aims to adjust the cooling power of the first cooling component 6 and the second cooling component 7 based on the deviation between the internal temperature information of the chamber and the second preset target temperature, using the PID controller 9, when the operating time of the first cooling component 6 reaches the lower limit of the preset operating time range, so that the internal temperature information of the chamber reaches the second preset target temperature. Specifically, the PID controller 9 is a classic feedback control algorithm. Using three parameters—proportional (P), integral (I), and derivative (D)—it dynamically adjusts the power output of the cooling components based on the deviation between the current and target temperatures to achieve precise temperature control and avoid temperature overshoot or oscillation. The preset operating time range falls within the time range covered by the theoretical cooling time. For example, if the theoretical cooling time range is 8:15-8:45, the preset operating time range is 8:20-8:30. Step B6 aims to stop the cooling components from operating to save energy after the ice pack has sufficiently stored cold. When the temperature inside the chamber rises back to the upper limit of the preset range due to heat infiltration, the system will restart cooling with a lower fourth preset cooling power to pull the temperature back to the lower limit of the preset range, thereby achieving energy-saving and stable temperature maintenance.

[0043] This application's solution addresses the shortcomings of traditional manual cooling insulated boxes by introducing a scheduled cooling strategy, achieving intelligent scheduling and ensuring that the temperature inside the box accurately reaches the target value at the user-specified time. It also optimizes the efficiency and stability of the cooling process. Specifically, the insulated box body 2 and the insulated box lid 3 are made of the same material, ensuring consistent thermal performance and avoiding deviations in insulation performance predictions due to material differences, thus providing a reliable foundation for subsequent thermodynamic models. The intelligent insulated box also includes a second temperature acquisition component 10 and a third temperature acquisition component 11, which collect ambient temperature information and internal temperature information, providing comprehensive temperature data input and enabling the system to accurately assess the external and internal thermal environments. Upon receiving a scheduled cooling command, the controller 9 executes the second cooling strategy, the core of which is the addition of a scheduled function, allowing users to set a scheduled usage time and a second preset target temperature, directly addressing the shortcomings of manual start-up and achieving automated control. In step B1, the preset heat capacity and preset thermal resistance are obtained, and the thermal characteristic parameters of the box body and lid are used to provide key inputs for model calculations, ensuring the accuracy of the theoretical cooling time prediction. Step B2 utilizes a pre-trained thermodynamic model to generate a theoretical cooling time based on preset heat capacity, preset thermal resistance, ambient temperature information, chamber internal temperature information, first temperature information, second temperature information, and a second preset target temperature. By integrating multi-source data, the model can dynamically adapt to actual conditions, avoiding prediction errors caused by a single parameter. Step B3 determines the cooling start time based on the scheduled usage time, theoretical cooling time, and preset safety redundancy time. Combining time factors and safety buffers, it prevents premature or late start-up, ensuring timely attainment of the target temperature. Step B4 controls both the first cooling component 6 and the second cooling component 7 to operate at a third preset cooling power when the cooling start time is reached, using high power for rapid cooling and shortening the initial cooling time. Step B5, when the operating time of the first cooling component 6 reaches the lower limit of the preset operating time range, the PID controller 9 adjusts the cooling power of the first cooling component 6 and the second cooling component 7 based on the deviation between the chamber internal temperature information and the second preset target temperature. Through feedback control mechanisms, the power is finely adjusted to reduce temperature fluctuations and ensure a smooth approach to the target value. Step B6 controls the first cooling component 6 and the second cooling component 7 to stop operating when the running time of the first cooling component 6 reaches the upper limit of the preset running time range, the first temperature information and the second temperature information are both less than or equal to the first preset target temperature, and the change rate of the first temperature information and the change rate of the second temperature information within the preset time window are both less than or equal to the second preset threshold. Then, when the internal temperature information of the chamber reaches the upper limit of the second preset range, the first cooling component 6 and the second cooling component 7 are controlled to operate at the fourth preset cooling power until the internal temperature information of the chamber reaches the lower limit of the second preset range. The second preset target temperature is within the second preset range and the fourth preset cooling power is less than the third preset cooling power. Energy is saved and overcooling is prevented through the low power maintenance mode, and the temperature is kept within the safe range.The solution proposed in this application makes full use of the dual-path cooling capacity of the first cooling component 6 and the second cooling component 7. In the scheduled cooling mode, it can achieve rapid pre-cooling and precise temperature control, which significantly improves the intelligence level and user experience of the insulated box.

[0044] In some preferred embodiments, step B3 includes: B31. Determine the thermal insulation performance of the enclosure based on the preset heat capacity and preset thermal resistance; B32. Based on the insulation performance of the enclosure, the ambient temperature information, and the internal temperature information of the enclosure, extract the corresponding redundancy duration from the pre-built mapping table of the combination of insulation performance, ambient temperature, and internal temperature of the enclosure and their corresponding redundancy duration as the preset safety redundancy duration. B33. Determine the cooling start time based on the scheduled usage time, theoretical cooling time, and preset safety redundancy time.

[0045] The thermal insulation performance of the enclosure is a quantitative assessment of the overall thermal insulation effect of the enclosure. It can be expressed as the heat loss coefficient (U-value), which is the amount of heat passing through a unit area per unit time under a unit temperature difference. The smaller the U-value, the better the thermal insulation performance. It should be understood that the preset heat capacity refers to the enclosure's ability to absorb or release heat when the temperature changes, and the preset thermal resistance refers to the enclosure's ability to prevent heat transfer. Therefore, the larger the preset heat capacity and preset thermal resistance, the better the enclosure's thermal insulation performance. The pre-built mapping table of combinations of thermal insulation performance, ambient temperature, and enclosure internal temperature and their corresponding redundancy duration is a database or lookup table that stores recommended redundancy durations under different operating conditions (combinations of enclosure thermal insulation performance, ambient temperature information, and enclosure internal temperature information). This mapping table can be trained and built through a large amount of experimental data, simulation, or historical operating data. For example, under different ambient temperatures, different enclosure internal temperatures, and different thermal insulation performances, the cooling strategy is run and the deviation between the actual cooling duration and the theoretical cooling duration is recorded. These deviations are stored as redundancy durations. The preferred formula for calculating the cooling start-up time in this embodiment is: Cooling start-up time = Scheduled usage time - Theoretical cooling duration - Preset safety redundancy duration.

[0046] This application's solution quantifies the thermal characteristics of the insulated box, providing fundamental parameters for subsequent redundancy duration calculations. This ensures that the evaluation of insulation performance is based on actual physical properties, avoiding biases caused by simple assumptions. Building upon this, it dynamically matches actual conditions using combined parameters and quickly obtains adaptive redundancy values ​​through a mapping table. This solves the problem that fixed redundancy durations cannot respond to changes in the environment and box status, improving the accuracy of redundancy settings. Finally, it integrates all dynamic factors for comprehensive calculation, ensuring a close match between startup time and reservation requirements, optimizing the efficiency and reliability of the cooling process. In this way, this application enables the reservation cooling strategy to more accurately predict and control the cooling process, thereby improving the overall performance and user experience of the intelligent control insulated box.

[0047] In some preferred embodiments, the duty cycle corresponding to both the first preset cooling power and the third preset cooling power is 100%. Duty cycle refers to the ratio of the time a signal is at a high level (or in a conducting state) to the total cycle time within a period. For cooling components, duty cycle is typically used to regulate their operating power, for example, by controlling the power supply time of cooling devices such as semiconductor refrigeration chips or compressors using pulse width modulation (PWM) technology. When the duty cycle is set to 100%, it means that the cooling component operates at full power throughout the entire operating cycle. This ensures that the cooling component can continuously receive maximum power input, thereby outputting its maximum cooling capacity. For example, for a semiconductor refrigeration chip, a 100% duty cycle means that it always operates at rated voltage and current during operation to achieve the strongest cooling effect. The first preset cooling power is the cooling power used in the initial stage (A1) of executing the first cooling strategy. Setting its corresponding duty cycle to 100% aims to enable the first cooling component 6 and the second cooling component 7 to quickly start and efficiently cool after receiving the cooling radiator command, thereby rapidly reducing the radiator temperature. The third preset cooling power is the cooling power used in the initial stage (B4) of executing the second cooling strategy. The purpose of setting its corresponding duty cycle to 100% is to enable the first cooling component 6 and the second cooling component 7 to immediately cool with high efficiency when the cooling start time set by the scheduled cooling command arrives, so as to ensure that the expected internal temperature is reached before the scheduled use time.

[0048] In some preferred embodiments, the first cooling assembly 6 includes a first thermoelectric cooler chip, with the top surface of the first cold plate 4 in contact with the cold end of the first thermoelectric cooler chip; the second cooling assembly 7 includes a second thermoelectric cooler chip, with the cold end of the second thermoelectric cooler chip in contact with the second cold plate 5. Both the first and second thermoelectric coolers in this embodiment are existing devices, and their operating principles will not be discussed in detail here.

[0049] In some preferred embodiments, the intelligent control insulation box further includes a liquid cooling component 12, which is disposed between the insulation box body 2 and the insulation box outer shell 1. The liquid cooling component 12 is connected to the hot end of the first semiconductor refrigeration chip and the hot end of the second semiconductor refrigeration chip. The liquid cooling component 12 is used to cool the hot ends of the first semiconductor refrigeration chip and the second semiconductor refrigeration chip using cooling fluid.

[0050] The liquid cooling assembly 12 is a cooling device that uses liquid as a heat transfer medium. Heat is carried away from the heat source through the circulation of the liquid, and then dissipated to the environment through a radiator. The liquid cooling assembly 12 may include a water pump, a liquid storage tank, coolant pipes, and one or more radiators (such as a water radiator). The liquid cooling assembly 12 is positioned between the insulation box 2 and the insulation box outer shell 1. This arrangement aims to fully utilize the space between the inside and outside of the insulation box, without occupying the effective volume inside the insulation box 2, while efficiently dissipating the heat generated by the thermoelectric cooling chip to the outside of the box, and preventing heat backflow from affecting the cooling effect of the insulation box. The liquid cooling assembly 12 is connected to the hot ends of the first and second thermoelectric cooling chips, ensuring that the cooling fluid in the liquid cooling assembly 12 can directly and efficiently absorb heat from the hot ends of the thermoelectric cooling chips, which is crucial for effective heat dissipation. The liquid cooling assembly 12 preferably cools the first and second ferrocooler chips by circulating cooling fluid to the hot ends of the first and second ferrocooler chips. Through continuous circulation of the cooling fluid, the heat generated at the hot ends of the ferrocooler chips is continuously carried away, so that the temperature of the first and second ferrocooler chips is maintained within a suitable operating temperature range, thereby ensuring their cooling efficiency and service life. Preferably, the control logic of the liquid cooling component 12 in this embodiment is as follows: when the first and second semiconductor refrigeration chips are cooling and the hot-end temperatures of both chips have not reached a preset temperature threshold, the liquid cooling component 12 is controlled to operate at a fifth preset cooling power (preferably 50%-70% of the rated power of the liquid cooling component 12); when the hot-end temperature of either the first or second semiconductor refrigeration chip reaches the first preset temperature threshold, the liquid cooling component 12 is controlled to operate at its rated power; when the hot-end temperatures of both chips decrease to a second preset temperature threshold (less than the first preset temperature threshold), based on the sum of the current cooling power of the first and second chips and the difference between the internal temperature information of the housing and the target temperature (first preset target temperature or second preset target temperature), the corresponding cooling power is extracted as the target cooling power from a pre-constructed mapping table of cooling power combination and temperature difference combination and its corresponding cooling power, and then the liquid cooling component 12 is controlled to operate at the target cooling power until the hot-end temperatures of both chips decrease to a third preset temperature threshold (less than the second preset temperature threshold).

[0051] This application's solution addresses the issue of insufficient heat dissipation at the hot end of semiconductor refrigeration chips by introducing a liquid cooling component 12, thereby improving cooling efficiency and system reliability. The liquid cooling component 12 is strategically positioned between the insulation box 2 and the outer shell 1, a location that ensures no interference with the internal insulation space while facilitating efficient heat removal from the heat source. The liquid cooling component 12 connects to the hot ends of both the first and second semiconductor refrigeration chips, enabling rapid heat transfer from the chips to the fluid and reducing thermal resistance. A continuous and stable heat dissipation process is maintained by circulating the cooling fluid, preventing temperature fluctuations. By actively and efficiently cooling the hot ends of the first and second semiconductor refrigeration chips, these chips are ensured to operate at their optimal performance, maintaining a higher temperature difference and significantly improving the overall cooling efficiency of the first and second radiators 4 and 5, thus enhancing the overall cooling capacity of the intelligent control insulation box. This thermal management mechanism effectively prevents chip overheating, extends their lifespan, and ensures the stability and reliability of the insulation box's cooling function.

[0052] In some preferred embodiments, the duration of the preset time window is 3-8 minutes.

[0053] In some preferred embodiments, the first radiator 4 and the second radiator 5 are filled with a phase change cold storage medium, and the process of adjusting the cooling power of the first cooling component 6 and / or the second cooling component 7 according to the deviation between the first temperature information and the second temperature information includes: C1. When the first temperature information is within the preset phase change temperature range and the rate of change of the first temperature information is less than the preset change threshold, the phase change cold storage medium in the first cold radiator 4 is considered to be in a phase change state. C2. When the second temperature information is within the preset phase change temperature range and the rate of change of the second temperature information is less than the preset change threshold, the phase change cold storage medium in the second cold radiator 5 is considered to be in a phase change state. C3. When both the phase change cold storage medium in the first cold radiator 4 and the phase change cold storage medium in the second cold radiator 5 are in a phase change state, the cooling power of the first cooling component 6 and / or the second cooling component 7 is adjusted according to the deviation between the first temperature information and the second temperature information, the position of the first temperature information within the preset phase change temperature range, and the position of the second temperature information within the preset phase change temperature range. C4. When the phase change cold storage medium in the first cold radiator 4 is in a phase change state or when all phase change cold storage media in the second cold radiator 5 are in a phase change state, maintain the cooling power of the cooling components corresponding to the phase change cold storage medium in a phase change state, and increase the cooling power of the cooling components corresponding to the phase change cold storage medium that is not in a phase change state.

[0054] The phase change energy storage medium filled in the first and second cold radiators 4 and 5 refers to a substance that undergoes a phase change at a specific temperature and absorbs or releases a large amount of latent heat. Its function is to provide additional cold storage capacity, so that the insulation box can maintain a lower temperature and extend the insulation time when the power is cut off or the cooling power is reduced. For example, the phase change energy storage medium can be a paraffin-based material with a specific melting point, a brine eutectic solution, or water ice. The preset phase change temperature range refers to the temperature range in which the phase change energy storage medium undergoes a phase change. This range is usually determined by the physical properties of the phase change material and is preset during system design. Since the temperature of the phase change energy storage medium will not change significantly even if it is continuously heated or cooled when it is in a phase change state, this embodiment can use the rate of change of the second temperature information being less than a preset change threshold as one of the judgment conditions for the phase change state. When the first or second temperature information is within the preset phase change temperature range and its rate of change is less than the preset change threshold, the controller 9 determines that the corresponding phase change energy storage medium is undergoing a phase change. The position within the preset phase change temperature range indicates the relative position of the current temperature within that range, thus indicating the progress of the phase change process. Adjusting the cooling power of the first cooling component 6 and / or the second cooling component 7 means that the controller 9 dynamically changes the cooling output of one or both cooling components based on the aforementioned judgments and information. For example, a proportional-integral-derivative (PID) control algorithm can be used to precisely adjust the power according to the temperature deviation and the phase change progress. Maintaining the cooling power of the cooling component corresponding to the phase change cold storage medium in the phase change state ensures the stable progress of the phase change process and avoids interruption or efficiency reduction due to power fluctuations. Increasing the cooling power of the cooling component corresponding to the phase change cold storage medium that is not in the phase change state accelerates its cooling process, enabling it to complete the phase change and reach the target temperature as quickly as possible, thereby optimizing the overall cooling efficiency and achieving temperature balance.

[0055] The solution proposed in this application effectively solves the problems of cooling efficiency and temperature control during the phase change process by filling the first radiator 4 and the second radiator 5 with a phase change cold storage medium and combining it with a smart controller 9 to dynamically adjust the cooling power of the first cooling component 6 and the second cooling component 7. Specifically, when the controller 9 receives a cooling radiator command, it first starts the first cooling component 6 and the second cooling component 7 for cooling. During this process, the first temperature acquisition component 8 and the second temperature acquisition component 10 continuously acquire the temperature information of the first radiator 4 and the second radiator 5. The controller 9 uses this temperature information to determine whether the phase change cold storage medium is in a phase change state through preset logic. When the first temperature information is within a preset phase change temperature range and its rate of change is less than a preset change threshold, the controller 9 determines that the phase change cold storage medium in the first radiator 4 is undergoing a phase change. Similarly, when the second temperature information is within a preset phase change temperature range and its rate of change is less than a preset change threshold, the controller 9 determines that the phase change cold storage medium in the second radiator 5 is undergoing a phase change. This judgment mechanism can accurately identify the phase change process because the temperature change rate will significantly decrease during the phase change. When the phase change energy storage medium of both radiators is in a phase change state, the controller 9 finely adjusts the cooling power of the first cooling component 6 and / or the second cooling component 7 based on the deviation between the first and second temperature information and their respective positions within the preset phase change temperature range. For example, if the temperature of one radiator is closer to the lower limit of the phase change range, indicating a faster phase change, the controller 9 may appropriately reduce its cooling power, while maintaining or slightly increasing the power of the other radiator with a slower phase change to achieve temperature balance and phase change synchronization between the two radiators. Furthermore, when only one radiator's phase change energy storage medium is in a phase change state, the controller 9 maintains the cooling power of the cooling component corresponding to that radiator to ensure the stable progress of its phase change process and fully utilize latent heat. Simultaneously, the controller 9 increases the cooling power of the cooling component corresponding to the radiator not in a phase change state to accelerate its cooling and enable it to enter the phase change state or reach the target temperature as soon as possible. This differentiated power regulation strategy enables efficient and direct transfer of cooling energy from the cold end of the semiconductor to the ice pack, and then to the chamber. This fully utilizes the cooling capacity of the phase change cryogenic medium, avoiding the energy waste and inaccurate temperature control issues associated with traditional cooling methods during phase change. In this way, the system can adaptively adjust the cooling output according to the actual phase change state of the ice pack, ensuring efficient and precise temperature control and maximizing the cooling potential of the phase change cryogenic medium.

[0056] As can be seen from the above, the intelligent control insulated box provided by this device, by setting up dual cooling radiators to cover key parts of the box, and combining temperature acquisition and intelligent controller 9 to execute cooling strategies, can accurately adjust the cooling power, achieve uniform temperature distribution and high energy efficiency, and has the beneficial effects of achieving uniform cooling of all parts of the box, energy efficiency, and avoiding temperature overshoot.

[0057] Secondly, this application also provides a method for controlling an intelligent insulated box, applied to the intelligent insulated box provided in the first aspect above. The method for controlling the intelligent insulated box includes the following steps: S1. Upon receiving a cooling radiator command, execute the first cooling strategy; the cooling radiator command includes a first preset target temperature; The first cooling strategy includes: A1.
