[0028] In the present invention, unless otherwise clearly defined and limited, the terms "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal connection or the interaction relationship of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] The following is a further description in conjunction with the accompanying drawings and specific embodiments:

[0030] As Figure 1 - Figure 2 shown, a portable intelligent medical refrigerated transport box applicable to extreme temperature environments includes a box body 1, and a handle 3 is installed on the box body 1. A heat insulation and preservation layer 9 is provided on the inner wall of the box body 1. The heat insulation and preservation layer 9 includes a heat insulation board, the heat insulation board has a vacuum interlayer, and a heat insulation material is provided in the vacuum interlayer. The vacuum interlayer of the heat insulation board utilizes the characteristic that the vacuum environment hardly conducts heat, greatly weakening heat conduction. The heat insulation materials, such as aerogel, glass fiber, etc., mainly hinder heat convection and heat radiation through a porous structure. The two start from different heat transfer mechanisms to achieve a comprehensive suppression of heat transfer. For example, in an extremely high temperature environment, the heat insulation material first blocks part of the heat, and the remaining heat is difficult to transfer into the box through the vacuum interlayer; in an extremely low temperature environment, the vacuum interlayer prevents the external low temperature from entering, and the heat insulation material further reduces the heat loss inside. A single vacuum interlayer may have the risk of a decrease in vacuum degree due to sealing problems, thereby reducing the heat insulation performance. The presence of the heat insulation material can make up for this defect to a certain extent. Even if the performance of the vacuum interlayer deteriorates, the heat insulation material can still provide a certain degree of heat insulation protection. At the same time, the heat insulation material can also buffer the impact of the outside world on the vacuum interlayer, prevent its structural damage, and extend the service life of the overall heat insulation and preservation layer. In addition, in extreme temperature environments, relying solely on the vacuum interlayer or the heat insulation material may be difficult to meet the strict requirements of the portable medical intelligent refrigerated transport box for temperature stability. The combination of the two can more effectively cope with the complex and changeable environmental temperature, ensure that the temperature inside the box is maintained within a suitable range, and guarantee the safety of medical supplies.

[0031] As Figure 1 - Figure 3 shown, the box body 1 has a storage compartment 5 and an electrical component installation compartment. The storage compartment 5 is used for storing medical substances. The upper end of the storage compartment 5 is open, and a box cover 2 is hingedly provided at the upper port of the storage compartment 5. The box cover 2 is used to open and close the storage compartment 5. In order to ensure the heat insulation and preservation effect of the present invention, a heat insulation and preservation layer structure should also be provided on the inner wall of the box cover 2. A lithium-ion hybrid capacitor compartment is provided in the electrical component installation compartment, and a power supply module 6 is installed in the lithium-ion hybrid capacitor compartment. The power supply module 6 uses a lithium-ion hybrid capacitor bank to supply power to each electrical component of the present invention. An integrated information processing module 7 and a temperature control system 8 are also installed in the electrical component installation compartment. An information display and control panel 4 is provided on the side wall of the box body 1. The power supply module 6, the integrated information processing module 7, and the temperature control system 8 are all electrically connected to the information display and control panel 4. A detachable hatch is provided at the lower end of the box body 1 for disassembling and replacing the lithium-ion hybrid capacitor bank. A charging socket is provided on the side wall of the box body 1, and the charging socket is electrically connected to the power supply module 6 for supplying power to the power supply module 6.

[0032] The energy supply module 6 of the present invention uses a lithium-ion hybrid capacitor, which has the following advantages compared with traditional lithium batteries:

[0033] First, the charge and discharge speed is fast: it can complete charging in a short time, quickly supply power to the temperature control system 8, and can quickly respond when an emergency occurs during transportation and rapid cooling is required or the equipment needs to be restarted after a short stop, ensuring that the temperature control system 8 operates in a timely manner and maintains a low-temperature environment.

[0034] Second, the cycle life is long: it means that during the entire usage period of the present invention, there is no need to frequently replace the power supply, reducing maintenance costs and environmental impact. At the same time, it also reduces the equipment downtime caused by power supply replacement, improving the usage efficiency of the present invention.

[0035] Third, the working temperature range is wide: it has stable performance at different ambient temperatures and can work well whether in a hot desert or a cold polar region, ensuring the normal operation of the present invention in various extreme temperature environments and the safety of transported items.

[0036] Fourth, the high power density: it can provide a large instantaneous power to meet the high-power requirements of the temperature control system 8 during startup, ensuring the stable operation of the equipment and avoiding poor refrigeration effects or equipment failures caused by insufficient power.

[0037] Fifth, it is lightweight: its weight is relatively light, which helps to reduce the overall weight of the present invention, facilitating handling and transportation, reducing energy consumption during transportation, and improving transportation efficiency. It is particularly suitable for transportation scenarios that require manual handling or have strict weight restrictions.

[0038] The integrated information processing module 7 of the present invention includes a temperature sensor and a BDS positioning system. The temperature sensing element of the temperature sensor extends into the storage compartment 5 for collecting temperature data in the storage compartment 5, and the BDS positioning system is used to obtain the position information of the medical cold transport box. The temperature control system 8 includes a heat conducting sheet, a sheet-shaped TEC semiconductor, a heat sink, and a fan. The heat conducting sheet is disposed on the bottom wall of the storage compartment 5, the sheet-shaped TEC semiconductor is closely attached to the heat conducting sheet, and the fan is installed on the sheet-shaped TEC semiconductor. A display screen, a data processing module, temperature adjustment buttons, and function conversion buttons are provided on the information display and control panel 4. As Figure 3As shown, the temperature adjustment button and the function conversion button are electrically connected to the signal input end of the data processing module. The temperature adjustment button is used to set the target temperature, and the function conversion button is used to switch the working mode. The signal output end of the data processing module is electrically connected to the input end of the temperature control system 8. The data processing module can control the operation of the sheet TEC semiconductor and the fan. The display screen is used to display the working information of the medical cold chain transportation box. The working information includes the actual temperature in the storage compartment 5 collected by the integrated information processing module 7, the position information of the medical cold chain transportation box, the target temperature set by the temperature adjustment button, and the working mode set by the function conversion button.

[0039] The data processing module of the present invention includes a signal receiving unit, a logic operation unit, a control signal output unit, and a data storage unit. Among them, the signal receiving unit is used to receive the target temperature signal input by the temperature adjustment button, the working mode switching signal input by the function conversion button, the actual temperature signal in the storage compartment 5 collected by the temperature sensor, and the position information signal of the medical cold chain transportation box obtained by the BDS positioning system. The logic operation unit compares and operates the received actual temperature signal and the target temperature signal, and generates a corresponding temperature control system regulation instruction according to the working mode signal input by the function conversion button and in combination with the preset control logic rules. The control signal output unit converts the regulation instruction generated by the logic operation unit into a control signal that can drive the temperature control system 8 to work, and outputs it to the input end of the temperature control system 8 to control the current direction and magnitude of the sheet TEC semiconductor, the start / stop and rotation speed of the fan. The data storage unit is used to store historical temperature data, position information data, equipment working mode records, and commonly used target temperature data set by the user, so as to facilitate the user to query the equipment operation status and analyze the equipment operation status.

[0040] Usage and working principle of the present invention: Assemble the fully charged lithium-ion hybrid capacitor into the lithium-ion hybrid capacitor compartment. Place the medical supplies to be transported in the storage compartment 5 and close the box lid 2. Lift the transport box through the handle 3 for movement and transportation. During use, the user sets the target temperature through the temperature adjustment button on the information display and control panel 4, and selects working modes such as refrigeration or heating through the function conversion button. The data processing module controls the operation of the temperature control system 8, and the information display and control panel 4 real-time displays the actual temperature inside the box body 1. The working modes of the present invention are divided into a refrigeration mode and a heating mode. In the refrigeration mode, when the temperature in the storage compartment 5 is higher than the set target temperature, it commands to control the sheet TEC semiconductor to apply a forward current for refrigeration, and adjusts the current intensity and fan speed according to the temperature difference. When the temperature in the storage compartment 5 is lower than the set temperature, a reverse current is output. At the same time, the data processing module transmits relevant information to the display screen for display and stores the data in the data storage unit. During transportation, the integrated information processing module 7 continuously collects temperature and position information, and the data processing module real-time regulates the temperature control system 8 to ensure that the temperature in the storage compartment 5 is stably within the target range, while the lithium-ion hybrid capacitor group stably supplies energy for the entire system. After use, the lithium-ion hybrid capacitor can be charged through a charger for the next use.

[0041] In summary, the present invention effectively expands the working temperature range, effectively improves the adaptability to extreme temperatures and can cover 99% of the extreme climate regions globally; the combined control of semiconductor refrigeration / heating and the precise regulation of the data processing module achieve a rapid response to the temperature change inside the box, greatly reducing the response time and temperature fluctuations, and can better guarantee the activity and quality of medical supplies. In addition, while meeting the functional requirements, the overall weight of the present invention can be further reduced, and the size can match the size of the carry-on luggage for air travel, facilitating portability and transportation. The integrated information processing module realizes temperature monitoring and positioning tracking, the information display and control panel is convenient to operate, and the data storage function facilitates the user to analyze the operation status of the device, with strong practicability.
