DETAILED DESCRIPTION

[0025] The present application will be further described below with reference to the accompanying drawings and examples. In the detailed description that follows, certain exemplary embodiments of the present application are described by way of illustration only. It is understood that those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present application. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of the claims.

[0026] As shown in Figures 1 and 2, the dual-temperature zone multi-modal logistics intelligent cold storage box of the present application embodiment includes a cold storage box 1 installed on a truck. A vertically arranged insulation panel 2 is provided inside the cold storage box 1. The insulation panel 2 divides the interior of the cold storage box 1 into a first temperature zone 3 and a second temperature zone 4 along the length of the cold storage box 1. A cold storage plate 5 and a cold storage unit are provided on the side of the first temperature zone 3 opposite the insulation panel 2. The insulation panel 2 is provided with an inter-temperature communication hole. A temperature-regulating fan 6 is installed in the inter-temperature communication hole to guide air from the first temperature zone 3 to the second temperature zone 4.

[0027] A first external communication hole is provided on the refrigerator 1, corresponding to the first temperature zone 3. A first temperature zone temperature-regulating fan 7 is installed at the first external communication hole, for guiding the air in the first temperature zone 3 to the outside of the refrigerator 1. A second external communication hole is provided on the refrigerator 1, corresponding to the second temperature zone 4. A second temperature zone temperature-regulating fan 8 is installed at the second external communication hole, for guiding the air in the second temperature zone 4 to the outside of the refrigerator 1. Temperature sensors are respectively provided on the inner wall of the refrigerator 1, corresponding to the first temperature zone 3 and the second temperature zone 4, for detecting the temperature of the first temperature zone 3 and the second temperature zone 4, respectively.

[0028] A control device and a temperature display device are also provided on the outside of the refrigerator 1. The temperature range temperature control fan 6, the first temperature zone temperature control fan 7, the second temperature zone temperature control fan 8, the temperature sensor, and the temperature display device are respectively connected to the control device.

[0029] In the embodiment of the present application, the cold storage box 1 can adopt a box structure with a heat-insulating effect in the prior art, and the heat-insulating vertical plate 2 can adopt a heat-insulating board to achieve the purpose of heat insulation.

[0030] In some embodiments, the cold storage plate 5 is installed flat on one side inner wall of the cold storage box 1 (the left inner wall in Figure 1), and the area of ​​the cold storage plate 5 exceeds 80% of the area of ​​the inner wall of the cold storage box 1. The cold storage plate 5 is arranged opposite to the heat-insulating vertical plate 2. Since the cold storage plate 5 has a large cooling area, the cooling effect is better, and the cooling effect of the first temperature zone 3 and the second temperature zone 4 can be achieved. In the embodiment of the present application, the cold storage plate 5 adopts a rectangular flat shell, which is installed vertically on the inner wall surface of the cold storage box 1, occupying a small space, and can maximize the space utilization in the first temperature zone 3. In addition, since the cold storage of the cold storage plate 5 is pre-utilized by the energy of the external AC power, compared with the energy of the refrigerated truck engine, the energy consumption is lower and the transportation cost is lower.

[0031] The cold storage plate utilizes the stored cold energy from the frozen coolant in the cold storage plate 5. Before transport, the cold storage unit can be connected to an external power source to store the coolant in the cold storage plate 5, essentially cooling it. During use, the melting of the coolant absorbs heat, continuously cooling the interior of the refrigerator 1. The cold storage plate 5 utilizes pre-stored cold energy, resulting in less temperature fluctuation within the refrigerator 1 than the prior art method of frequently turning the compressor on and off, ensuring a constant temperature.

[0032] The refrigerated box in the embodiment of the present application uses a group of cold storage plates in combination with multiple fans to meet the different refrigeration requirements of two temperature zones. Compared with the use of multiple evaporators in the prior art, it is not only less expensive, but also has a reduced overall weight and corresponding low transportation energy consumption, which can increase the total amount and transportation mileage of transported goods.

[0033] Since the density of cold air is greater than that of warm air, cold air tends to sink. Therefore, the temperature-regulating fan 6 is arranged near the lower part of the insulation vertical plate 2 to shorten the time for cold air to enter the second temperature zone 4.

[0034] The first and second external communication holes are located on the top wall of the refrigerator 1 and do not interfere with other structures. Furthermore, to prevent rainwater from entering the first and second external communication holes, a semi-enclosed rain shield can be installed above the outer wall of the refrigerator 1 at the corresponding locations of the communication holes. This not only shields the upper portion of the communication holes but also allows for air flow.

[0035] Independent doors are respectively provided on the side walls of the refrigerated box 1 corresponding to the first temperature zone 3 and the second temperature zone 4. The two independent doors are located on the same side of the refrigerated box 1. The two independent doors correspond to the first temperature zone 3 and the second temperature zone 4 respectively, so that the first temperature zone 3 and the second temperature zone 4 can be opened separately to meet different loading and unloading requirements.

[0036] The apertures of the temperature zone connecting holes, the first external connecting holes and the second external connecting holes are small, and a fan is installed at each connecting hole to achieve the purpose of air circulation and air replenishment. In response to the fan not running, there is no forced flow of air. At this time, although the connecting holes are open, the impact on the internal cooling demand is small and can be ignored.

[0037] In the field of refrigerated containers, frozen transportation generally refers to transportation at temperatures between -20°C and -10°C; refrigerated transportation generally refers to transportation at temperatures between -5°C and 8°C; and normal temperature transportation generally refers to transportation at temperatures between 20°C and 25°C. Therefore, as long as the interior of the refrigerated container 1 is within a certain temperature range, the temperature sensor can be placed in the middle of the interior of the refrigerated container 1 in the vertical direction, so that the detected temperature data is representative.

[0038] The working principle and operation of the refrigerator in the embodiment of the present application are described below.

[0039] The control device can realize the following multiple usage modes by controlling the opening and closing of multiple fans, wherein the structural block diagram of the refrigerator is shown in FIG5 .

[0040] First usage mode: the first temperature zone 3 is a refrigerated cargo box, and the second temperature zone 4 is a normal temperature cargo box.

[0041] Turn off the first temperature zone temperature regulating fan 7, turn off the inter-temperature zone temperature regulating fan 6, and turn on the second temperature zone temperature regulating fan 8. At this time, the cold storage plate 5 cools normally, and the thermal insulation performance of the refrigerator 1 is used to achieve the temperature zoning effect and temperature maintenance capability of the first temperature zone 3 and the second temperature zone 4. See Figure 3. The temperature sensors in the first temperature zone 3 and the second temperature zone 4 are used to monitor the temperature fluctuations in the temperature zones, and the data is transmitted to the control device, which then controls the opening and closing of each fan to adjust the temperature fluctuations.

[0042] Second usage mode: the first temperature zone 3 is a refrigerated cargo box, and the second temperature zone 4 is a refrigerated cargo box.

[0043] Turn off the first temperature zone temperature regulating fan 7, turn on the temperature interval temperature regulating fan 6, turn off the second temperature zone temperature regulating fan 8, and let the cold storage plate 5 cool as usual. Use the thermal insulation performance of the refrigerator 1 to achieve the temperature zoning effect and temperature maintenance capability of the first temperature zone 3 and the second temperature zone 4. See Figure 4. When the temperature of the second temperature zone 4 is too low, turn off the temperature interval temperature regulating fan 6, turn on the second temperature zone temperature regulating fan 8 to increase the temperature; when the temperature of the second temperature zone 4 reaches the requirement, turn off the temperature interval temperature regulating fan 6, and use the box performance to keep warm; when the temperature of the second temperature zone 4 is too high, use the temperature interval temperature regulating fan 6 again to transfer the cold air from the first temperature zone 3 to the second temperature zone 4.

[0044] The third usage mode: the first temperature zone 3 is a refrigerated cargo box, and the second temperature zone 4 is a refrigerated cargo box.

[0045] Turn off the first temperature zone temperature regulating fan 7, turn on the temperature interval temperature regulating fan 6, turn off the second temperature zone temperature regulating fan 8, the cold storage plate 5 is charged with cold as usual, the cold storage plate 5 is charged with cold as usual, the temperature interval temperature regulating fan 6 remains on, and the first temperature zone 3 and the temperature sensor in the first temperature zone 3 are used to monitor the temperature fluctuations in the temperature zones.

[0046] Usage mode 4: The first temperature zone 3 is a normal temperature cargo box, and the second temperature zone 4 is a normal temperature cargo box.

[0047] Turn on the first temperature zone temperature control fan 7, turn on the temperature zone temperature control fan 6, turn on the second temperature zone temperature control fan 8, the cold storage plate 5 does not charge cold, and use the temperature sensors in the first temperature zone 3 and the second temperature zone 4 to monitor the temperature fluctuations in the temperature zones.

[0048] In the corresponding usage mode, the temperature sensor monitors the temperature inside the temperature zone and transmits it to the control device. The control device can control the corresponding fan to turn on and off, adjust the temperature fluctuations of the internal temperature zone, and meet the temperature requirements in the corresponding usage mode.

[0049] The refrigerator in the embodiment of the present application uses a combination of a cold storage plate 5 and multiple fans, so that the two temperature zones can realize a variety of different usage modes to meet different usage needs. It has the characteristics of simple control, low cost, and good practicality.
