The top of the box shell 7 is open, and the top of the box shell 7 is hinged with the box cover 16 . As shown in FIG. 5 , a refrigeration circuit composed of a compressor 2 , a dry filter 3 , an evaporator, a capillary tube 6 and a condenser 8 is arranged inside the box shell 7 . As shown in FIG. 1 , an inner tank 1 is arranged inside the box shell 7 , and a partition 15 is vertically arranged inside the inner tank 1 . The partition 15 divides the inner space of the liner 1 into two independent spaces of the freezer 14 and the refrigerator 17; the partition 15 can also be removed to make only the refrigerator or the freezer, so as to meet the needs of different fresh orders. Category temperature requirements. A cooling agent layer 11 is provided on the outer periphery of the inner container 1 , as shown in FIG. 1 and FIG. 2 , and the evaporator includes a first evaporator 13 and a second evaporator 18 . As shown in FIG. 5 , the first evaporator 13 is connected in series in the refrigeration circuit, and the second evaporator 18 is connected in parallel with both ends of the first evaporator 13 through a parallel branch. The parallel branch where the second evaporator 18 is located is connected in series with a solenoid valve 20 , and the solenoid valve 20 can control the on-off of the branch where the second evaporator 18 is located. The first evaporator 13 is in close contact with the outer wall of the inner container 1 corresponding to the freezing chamber 14 to cool the freezing chamber 14 . The second evaporator 18 is in close contact with the outer wall of the inner container 1 corresponding to the refrigerating chamber 17 to cool the refrigerating chamber 17 . The distribution box is equipped with a refrigeration temperature control device: a single chip microcomputer 21, a first temperature sensing element 4 and a second temperature sensing element 5 are installed in the box shell 7, the first temperature sensing element 4 measures the temperature in the refrigerator compartment 17, and the second temperature sensing element The temperature element 5 measures the temperature in the freezer compartment 14, and the single-chip microcomputer 21 is connected with the compressor 2, the electromagnetic valve 20, the first temperature-sensing element 4 and the second temperature-sensing element 5 by wires respectively. In order to facilitate heat preservation during transportation and reduce energy consumption, as shown in Figures 1 and 2, an inner shell 10 is provided between the box shell 7 and the inner tank 1, and an insulating layer 9 is filled between the inner shell 10 and the box shell 7.

In cooling mode, the first temperature-sensing element 4 and the second temperature-sensing element 5 can sense the temperature in the freezing chamber 14 and the refrigerating chamber 17 respectively, and transmit the temperature values to the single-chip microcomputer 21 . When the internal temperature of the refrigerating chamber 17, that is, the temperature of the high temperature zone, reaches the set value, the single-chip microcomputer 21 controls the solenoid valve 20 to act, and the branch of the second evaporator 18 is interrupted. Refrigeration in the low-temperature zone; when the temperature in the low-temperature zone reaches the set requirement, the single-chip microcomputer 21 controls the compressor 2 to stop working. When the temperature in the low-temperature zone deviates from the set temperature, the single-chip microcomputer 21 controls the compressor 2 to start working, until the temperature in the low-temperature zone reaches the set value, the single-chip microcomputer 21 controls the compressor 2 to stop working again, and the cycle works like this. During the above period, when the temperature in the high temperature zone deviates from the set temperature, the electromagnetic valve 20 is opened, and the second evaporator 18 cools the high temperature zone. Coolant layer 11 is arranged around the inner tank, which forms a contact thermal resistance when the system is in cooling mode, which effectively reduces the outward penetration of cold energy, improves cooling efficiency, and accumulates cold energy at the same time. When the system is in the cold storage mode, the cold storage layer 11 transfers the previously stored cold energy to the box in one direction, and continuously maintains the previously reached set temperature. Due to the combination of refrigeration and cold storage, it can meet the distribution temperature and ensure the quality of the goods in the face of power outages that may occur during the delivery of fresh orders.

As shown in Figure 2, the cold storage agent layer 11 can be composed of several cold storage strips. A plurality of parallel slots are formed between them, each slot is filled with a bar-shaped cold storage bar. When faced with different order quantities, it is only necessary to change the filling quantity of cold storage strips.
