The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
Specific embodiment:
With reference to Fig. 1, biologics cold chain transportation device described in the present embodiment, comprise insulation can 1, be located at the hold-over plate 2 in insulation can 1, be located at the evaporator 3 in hold-over plate 2, be located at the temperature sensor 4 in insulation can 1, and the condenser 5, refrigerating compressor 6, temperature controller 7 and the dc-battery 8 that are arranged at respectively insulation can 1 outside;
Described evaporator 3 has an input port and a delivery port, the input port of described evaporator 3 is connected with the delivery port of described condenser 5 by choke manifold, the input port of described condenser 5 is connected with the delivery port of described refrigerating compressor 6 by pipeline, and the input port of described refrigerating compressor 6 is connected with the delivery port of described evaporator 3; By evaporator 3, condenser 5, cold compressor 6, refrigerant and refrigeration system of pipeline valve module composition.
A signal input part of described temperature controller 7 is connected with the signal output part of temperature sensor 4, a signal output part of described temperature controller 7 is connected with the signal input part of refrigerating compressor 6, and the temperature value being detected according to temperature sensor 4 by temperature controller 7 is controlled refrigerating compressor 6 and started or stoped;
Described dc-battery 8 is 24V dc-battery.Described dc-battery 8 is connected with 220V source of AC by a charger.The volume of described insulation can 1 is 60~100L.
Principle of work of the present utility model:
(1) use front charging, precooling, comprise that hold-over plate is filled to cold-peace to charge to 24V dc-battery, with 220V source of AC by being converted to 24V direct supply, start refrigerating compressor, make refrigeration system operation, refrigerant enters the evaporator being located in hold-over plate to carry out evaporating lower than agent for storage of coldness phase transformation crystallization point (4 ℃), continue to absorb the heat of agent for storage of coldness, make the final phase transformation crystallization of agent for storage of coldness, by temperature sensor, experience insulation the temperature inside the box, transfer to temperature controller, by temperature controller, adjust and control temperature, temperature controlling range: 2~4 ℃, when insulation the temperature inside the box≤2.5 ℃, refrigerating compressor shuts down, refrigeration system break-off, when insulation the temperature inside the box is 6.5 ℃, refrigerating compressor starts running, refrigeration system operation.
With 220V source of AC, by charger, 24V dc-battery is charged, battery charging is complete, and automatic power-off function of charger, stops battery charging.
(2) drop into cold chain transportation process: by transfer switch, connect 24V dc-battery power supply, refrigerating compressor and refrigeration system thereof are controlled start-stop by temperature controller, thereby the temperature inside the box is controlled in the scope of 2~8 ℃.
For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and distortion all should belong to the protection domain of the utility model claim within.
