All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Examples

The compressor 31 is used for sucking and compressing a low pressure area into a high temperature and high pressure gas, the cooling system 30 adopts a multi-stage cooling mode, the first condenser 32 and the second condenser 33 are components for cooling and converting the high temperature and high pressure gas or gaseous refrigerant into a liquid state, the evaporator 34 is a component for converting the liquid refrigerant into a gas state, absorbing heat and evaporating into a gas state, thereby reducing the temperature inside the cabinet, the throttle valve 35 is used for controlling the flow rate and pressure of the refrigerant in the cooling system 30, and is used for adjusting the flow rate and pressure in the cooling system 30 so as to maintain the normal operation of the system. Optionally, the throttle valve 35 includes a throttle element 351, a drive mechanism 352, a throttle first air inlet 353, a throttle second air inlet 354, and a throttle air outlet 355;

Optionally, the compressor 31 selects the variable frequency compressor 31, and the running speed of the compressor 31 is controlled by adjusting the power voltage and frequency of the variable frequency compressor 31 to adapt to the actual refrigeration requirement.
Specifically, the variable frequency compressor 31 is selected as the compressor 31, which has the performance of adjusting the refrigerating capacity, improving the load efficiency, smoothly starting and stopping, and stabilizing the temperature. Regulating the refrigerating capacity: by varying the rotational speed of the compressor 31, the cooling capacity can be flexibly adjusted. When the cooling load is low, the compressor 31 can be operated at a low speed, the refrigerating capacity is reduced, and the energy waste is avoided. And when the cooling load is high, the compressor 31 can be operated at a high speed, providing a larger cooling capacity to meet the demand.
Load efficiency is improved: the conventional constant speed compressor 31 is inefficient at low loads. The variable frequency compressor 31 can adjust the rotation speed in real time according to the actual load demand, so that the variable frequency compressor can operate in a higher partial load efficiency area, thereby improving the overall energy efficiency.
Smooth start-stop: the conventional constant speed compressor 31 needs to instantaneously absorb a large amount of current at the time of starting and generates large noise and vibration. The variable frequency compressor 31 can control the current change in the starting process through the smooth starting and stopping function, gradually increase the rotating speed, reduce the starting impact and reduce the energy loss.
Stabilization temperature: the inverter compressor 31 can more precisely control the temperature of the target area.

Optionally, the cooling system 30 further comprises an inlet line 36 and an outlet line 37,

Optionally, the cabinet is made of a heat insulating material to reduce heat transfer.
Working principle: the cooling system 30 adopts a multi-stage cooling and energy-saving operation mode.
Primary cooling: the compressor 31 sucks and compresses low-pressure gas into high-temperature and high-pressure gas, the high-temperature and high-pressure gas enters the first condenser 32, heat is released under the action of refrigerant, the high-temperature and high-pressure gas is cooled and condensed into liquid state, the liquid-state refrigerant enters the evaporator 34 through the throttle valve air outlet 355, the evaporator 34 evaporates the cooled air into the cabinet, the liquid-state refrigerant is contacted with the air or other objects and absorbs heat, so that the temperature in the cabinet is reduced, the low-pressure gas is sucked by the compressor 31 again, and the low-pressure gas is circulated and reciprocated to realize a continuous refrigeration effect.
And (3) secondary cooling: the compressor 31 sucks and compresses low-pressure gas into high-temperature and high-pressure gas, the high-temperature and high-pressure gas sequentially enters the first condenser 32 and the second condenser 33, heat is released under the action of refrigerant, the low-pressure gas is cooled and condensed into liquid, the liquid refrigerant enters the evaporator 34 through the throttle valve air outlet 355, the evaporator 34 evaporates the cooled air into the cabinet, the liquid refrigerant is contacted with the air or other objects and absorbs heat, so that the temperature in the cabinet is reduced, the low-pressure gas is sucked by the compressor 31 again, and the continuous refrigeration effect is realized.
Energy-saving operation: by varying the rotational speed of the compressor 31, the cooling capacity can be flexibly adjusted. When the internal temperature of the cabinet is lower than the set threshold, the compressor 31 can be operated at a low speed, and the position or opening of the throttling element 351 is changed, so that the refrigerating capacity is reduced, and energy waste is avoided. And when the internal temperature of the cabinet is higher than the set threshold, the compressor 31 can be operated at a high speed to provide a larger refrigerating capacity to meet the demand.
The outdoor refrigerating cabinet provided by the embodiment of the utility model has the beneficial effects that:
Improving energy efficiency: the multi-stage cooling system 30 may be cooled at various stages using a suitable cooling medium, as desired. By distributing the cooling load to different cooling levels, the energy efficiency of the cooling system 30 may be improved. The lower temperature required portion may use a low temperature cooling medium and the higher temperature required portion may use a high temperature cooling medium to minimize energy consumption.
The running cost is reduced: the multi-stage cooling system 30 can adjust the number of cooling stages and the operation state according to actual demands to avoid excessive cooling and energy waste. According to the load change and the change of the environmental condition, the proper cooling level and the operation mode can be flexibly selected, thereby reducing the operation cost.
Enhancing system reliability: the multi-stage cooling system 30 may improve redundancy and reliability of the system. When one level of cooling medium fails or requires maintenance, other levels of cooling medium may be selected to maintain proper operation of the system. This helps to reduce production breaks and equipment damage due to a single point of failure.
And the flexibility of the system is improved: the multi-stage cooling system 30 may be adjusted to different process requirements and environmental conditions. By selecting proper cooling level and operation mode, the requirements of different processes on temperature and cooling speed can be met. The increased system flexibility also enables the cooling system 30 to accommodate new process requirements and changing production requirements.
