Description

Technical Field

[0001] The utility model relates to the field of logistics temperature control equipment, in particular to a mobile active temperature control logistics equipment. Background Art

[0002] Cold chain logistics is a professional logistics that uses temperature control, preservation and other technical processes and facilities and equipment such as cold storage, refrigerated trucks and refrigerated boxes to ensure that cold chain products are always kept at a specified temperature environment throughout the entire process of primary processing, storage, transportation, circulation processing, sales and distribution.

[0003] With the rapid growth of market demand for cold chain products such as meat, fruits, vegetables, aquatic products, dairy products, frozen foods, vaccines, biological preparations, and medicines in my country, the business environment continues to improve, promoting the rapid development of cold chain logistics, but it still faces many prominent bottlenecks and pain points, making it difficult to effectively meet market demand. In the overall layout of the modern cold chain logistics system, we will create the "321" cold chain logistics operation system, the third level of the "short board project of cold chain logistics facilities at both ends of the three-level cold chain logistics nodes, focus on the "first kilometer" of agricultural product production areas, and build a number of small mobile storage facilities with insurance, pre-cooling and other functions in the fields in combination with actual conditions, and build terminal cold chain logistics facilities for the "last kilometer" consumer demand in the city. Encourage logistics companies to integrate urban cold chain and normal temperature cargo distribution on a large scale, increase the promotion and application of multi-temperature zone delivery vehicles, cold storage insulation boxes and insulation cabinets, and promote the development of multi-temperature distribution in various forms.

[0004] Currently, there are two types of cold chain transportation: one is refrigerated transportation, which is to freeze the goods at the departure point, and then use insulated boxes to keep the goods as low as possible during transportation; the other is to use refrigerated trucks to install a refrigeration system in the truck, and keep the low temperature through cooling during transportation.

[0005] Technical issues:

[0006] 1. The temperature control of cold storage plate insulation boxes or ordinary insulation boxes is not accurate, the insulation time is short, there is no real-time temperature monitoring function, and problems such as "broken chain" and "pseudo cold chain" in cold chain logistics are prominent, and there are many product quality and safety risks related to this.

[0007] 2. The large volume of refrigerated trucks requires a high packing rate and low transportation efficiency.

[0008] 3. Cold storage and insulation box. The cold storage plate will take up a lot of space in the box, the effective transportation volume is low, and the insulation time of the cold storage and insulation box is short, so there is a risk of "breaking the chain" in the cold chain.

[0009] 4. It is difficult for ordinary insulated boxes or refrigerated transport vehicles to quickly change the temperature. In cold seasons, ordinary trucks cannot transport freeze-sensitive goods.

[0010] 5. It is not possible to use trucks without refrigeration equipment to transport refrigerated and frozen goods. Even if ordinary insulated boxes are used for insulation, the quality cannot be controlled and the problem of multi-temperature distribution cannot be solved.

[0011] 6. The energy consumption level in the cold chain logistics and transportation links is relatively high. In the context of achieving carbon peak and carbon neutrality goals, it faces a prominent contradiction between scale expansion and carbon emission control. Utility Model Content

[0089] The equipment cabin 2 is arranged at the lower end of the box body 1, and the equipment cabin 2 includes a refrigeration unit 21, a power unit 22, a panel 23 and a control box 24. Panels 23 are arranged on the four sides of the equipment cabin 2, and the control box 24 is arranged on the panel 23. Pipe fittings such as a compressor 211, a condenser 212, and a throttle valve 213 are arranged inside the refrigeration unit 21; the compressor 211 compresses the low-pressure steam from the evaporator, and after being compressed into high-temperature and high-pressure steam, enters the condenser 212 for cooling, condenses into high-pressure liquid, and then throttles through the throttling mechanism, throttling into a low-temperature and low-pressure gas-liquid mixture, enters the evaporator 83 for evaporation and heat absorption, and the refrigerant gas returns to the compressor 211 to circulate until the temperature in the cavity reaches the set temperature, and the compressor 211 stops working. This function can achieve refrigeration and freezing functions of 5 (±3) ° C to minus 18 (±3) ° C. When the outside temperature is very low in winter, the logistics equipment can automatically control the PTC heater 82 to start through the thermostat 402 to realize the heating function, and can achieve temperature control of 5 (± 3) ° C-15 (± 3) ° C. Special (antifreeze requirements) commodities with corresponding temperature requirements can be transported. The power unit 22 is provided with a battery 221, and the battery 221 is connected to a charger 222 and an electric control box 223.

[0090] An air duct 84 is arranged at the back and top of the cavity 7, and a finned copper tube evaporator 83 and an evaporating fan 81 are arranged at the top of the air duct 84, which can make the air in the cavity circulate quickly. The air cooling method can meet the requirement of fast pre-cooling when the box is empty. At the same time, the temperature is relatively uniform. The evaporator 83 can be replaced during maintenance.
