[0037] As Figures 1 to 4 shown, the refrigerated transportation device provided in this embodiment includes a refrigeration system 100, a heating system 200, a controller 300 and a transportation box 400. The refrigeration system 100 includes a compressor 101, a condenser 102, an evaporator 103, a first blower 104 and an expansion valve 105. The compressor 101, the condenser 102, the expansion valve 105 and the evaporator 103 are connected in sequence. The output end of the evaporator 103 is connected to the input end of the compressor 101, and the first blower 104 is arranged corresponding to the evaporator 103. The heating system 200 includes the first blower 104 and a heater 201, and the heater 201 is arranged corresponding to the first blower 104. The controller 300 is in signal connection with the refrigeration system 100 and the heating system 200. The transportation box 400 forms a storage space 410 and an equipment space 420. The storage space 410 is used for storing items, and the equipment space 420 is used for accommodating the refrigeration system 100, the heating system 200 and the controller 300.

[0038] The refrigerated transportation device provided in this embodiment includes a refrigeration system 100, a heating system 200, a controller 300 and a transportation box 400. The transportation box 400 forms a storage space 410 and an equipment space 420. The refrigeration system 100, the heating system 200 and the controller 300 are integrally installed in the equipment space 420, without occupying the effective volume in the storage space 410, improving the volume utilization rate of the storage space 410, having a compact structure, a neat and beautiful layout, being simple and convenient for installation and maintenance, and being capable of being used for storing and transporting materials between the field and the suburbs, reducing the cost of cold chain transportation.

[0039] Preferably, the storage space 410 of the refrigerated transportation device is set to be 4 cubic meters to 7 cubic meters, and the temperature inside the storage space 410 is between -20 degrees Celsius and +10 degrees Celsius to ensure the freezing and refrigeration requirements during transportation.

[0040] Furthermore, the device space 420 includes a first space 421 and a second space 422. The first space 421 is in communication with the storage space 410, and the evaporator 103, the first blower 104, and the heater 201 are located in the first space 421. Specifically, the transport box 400 includes a partition 430 for isolating the storage space 410 and the device space 420. The first space 421 is located above the second space 422, and air inlet holes 431 and air outlet holes 432 are provided in the corresponding part of the partition 430 of the first space 421. The first blower 104 can blow the air in the first space 421 and the storage space 410 to circulate. When the refrigeration system 100 operates, the evaporator 103 absorbs the heat in the air, and the first blower 104 blows the cold air near the evaporator into the storage space 410 through the air inlet hole 430. The hot air in the storage space 410 enters the first space 421 through the air outlet hole 432, realizing the circulation of the cold air in the storage space 410. When the heating system 200 operates, the heater 201 heats the air in the first space 421, and the first blower 104 blows the hot air into the storage space 410. The cold air in the storage space 410 only enters the first space 421, realizing the circulation of the hot air in the storage space 410. In this embodiment, a heat insulation layer is provided outside the first space 421 to insulate the evaporator 103. The heater 201 uses a PTC heater, which has a small thermal resistance, excellent heat dissipation performance, high efficiency, and is safe and reliable.

[0041] Optionally, fins are provided outside the evaporator 103 to increase the surface area of the evaporator 103 and improve the heat exchange efficiency between the evaporator 103 and the air. In addition, the heater 201 is located between the evaporator 103 and the first blower 104. When the heating system 200 operates, the first blower 104 blows the hot air towards the evaporator 103, so that the fins mix the hot air evenly to prevent local overheating of the hot air.

[0042] When the refrigerated transportation device is operating in heating mode, the first blower 104 starts the air supply circulation. The cold air is heated and raised in temperature by the heater 201. The hot air is evenly mixed through the core copper tube and fins of the evaporator 103. The first blower 104 sends the hot air into the storage space 410 for circulation, and the heating work cycle is carried out repeatedly.

[0043] Further, the refrigeration system 100 further includes a first separator 111. The first separator 111 is connected between the compressor 101 and the condenser 102. The first separator 111 is used to separate the high-temperature and high-pressure refrigerant gas and lubricating oil flowing out of the compressor 101, allowing the gas to enter the condenser 102. The separated lubricating oil returns to the compressor through the suction port of the compressor 101 to maintain the good lubrication and sealing performance of the compressor 101.

[0044] Further, the refrigeration system 100 further includes a high-pressure switch 107. The high-pressure switch 107 is disposed on the pipeline between the compressor 101 and the condenser 102 and is used to control the switches of the compressor 101 and the condenser 102.

[0045] Further, the refrigeration system 100 further includes a second fan 109. The second fan 109 is correspondingly disposed on the condenser 102. The second fan 109 blows air to the condenser 102 for dissipating heat from the condenser 102.

[0046] Further, the refrigeration system 100 further includes a dryer 106. The dryer 106 is disposed on the pipeline between the condenser 102 and the evaporator 103 and is used to filter impurities and moisture.

[0047] Further, the refrigeration system 100 further includes a second separator 112. The second separator 112 is connected between the output end of the evaporator 103 and the input end of the compressor 101 to separate the refrigerant flowing out of the evaporator 103 into gas and liquid, ensuring that the gaseous refrigerant enters the compressor 101.

[0048] Further, the refrigeration system 100 further includes a low-pressure switch 108. The low-pressure switch 108 is disposed on the pipeline between the output end of the evaporator 103 and the input end of the compressor 101.

[0049] When the refrigeration transportation device is in refrigeration operation, the system refrigerant is compressed into a high-temperature and high-pressure gas by the compressor 101, then enters the condenser 102 to be cooled into a high-pressure subcooled liquid, enters the dryer 106 to filter impurities and moisture, enters the expansion valve 105 to throttle and depressurize and cool into a liquid-gas mixture, enters the evaporator 103 to evaporate and absorb the heat in the storage space 410 to become a low-pressure vapor, and is sucked by the compressor 101 and compressed into a high-temperature and high-pressure gas, thus completing the refrigeration cycle and continuously performing the refrigeration working cycle.

[0050] Furthermore, the refrigerated transportation device further includes a defrosting system 500. The defrosting system 500 includes a defrosting switch 501. The output end of the compressor 101 is communicated with the input end of the evaporator 103. The defrosting switch 501 is arranged on the pipeline between the output end of the compressor 101 and the input end of the evaporator 103. When defrosting the evaporator 103, the defrosting switch 501 is turned on. The refrigerant in the system is compressed into high-temperature and high-pressure gas by the compressor 101. The high-temperature hot gas enters the core of the evaporator 103. At this time, the ice and frost on the surface of the evaporator 103 absorb heat and melt. The high-temperature hot gas becomes low-temperature vapor. The low-temperature vapor is sucked into the compressor 101 and compressed into high-temperature and high-pressure gas, thus completing the defrosting cycle. The defrosting work cycle is carried out repeatedly.

[0051] To expand the applicable range of the refrigerated transportation device, the refrigerated transportation device can be powered by mains electricity (AC220V) and the backup power supply of the cold chain box (DC500V). Different power supply systems can be selected according to the change of the application scenario. During the connection of the mains electricity, while the mains electricity supports the operation of the refrigeration system, it can also charge the backup power supply.

[0052] It should be noted that the traditional cold chain transportation box has the following deficiencies: 1. It cannot monitor the relevant parameters of the cold chain logistics in real time, such as temperature, humidity, air cleanliness, etc., and cannot give an alarm in time, so it cannot effectively guarantee the quality of the cold chain logistics; 2. It cannot provide intelligent scheduling and route planning functions. According to the current road conditions and the real-time status of the goods, it cannot improve the efficiency of the cold chain logistics; 3. It cannot provide real-time tracking and tracing functions. Customers cannot view the status and location of their goods in real time, thus reducing the transparency of the cold chain logistics. To solve the above technical problems, the refrigerated transportation device provided in this embodiment is provided with a controller 300, which can monitor various working conditions of the refrigerated transportation device in real time.

[0053] Specifically, the controller 300 includes a temperature sensor, which can detect the temperature in the storage space 410 in real time, and can control the switches of the refrigeration system 100, the heating system 200 and the defrosting system 500 to realize flexible regulation of the temperature in the storage space 410. In addition, through the controller 300, the recording and export of temperature data can also be realized. When a fault occurs, the manufacturer can more accurately judge the fault point, and the user can enjoy more convenient after-sales service. The manufacturer can accurately share the temperature data of a certain device for a certain period of time according to a large amount of refrigeration working condition data, and improve the performance and reliability of the refrigerated transportation device in a targeted manner.

[0054] Furthermore, the controller 300 further includes an alarm system, including fault recording, fault alarm, power monitoring display, battery alarm, etc., which is convenient for monitoring and managing the working condition of the refrigerated transportation device.

[0055] Furthermore, the controller 300 may further include a remote monitoring module, which monitors the working conditions in real time and uploads and saves them to the cloud server. The information that the device can detect includes but is not limited to return air temperature, defrosting temperature, compressor exhaust temperature, ambient temperature, power supply voltage, fault information, on / off state, operation mode, satellite positioning, moving speed, signal strength, etc. Preferably, the data upload period of the remote monitoring module is to upload a set of data every twenty seconds, and the saving period is as long as one year. By using the remote monitoring system, the consignor can view the temperature and location information of the consigned goods in real time, thereby improving the user experience.

[0056] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
