Description
Technical Field
[0001] The utility model relates to the technical field of cold storage, and more specifically to a cold-filling refrigeration box and a cold-filling system. Background Art
[0002] With the improvement of people's living standards and the pursuit of healthy diet quality, the requirements for food safety and drug effectiveness are getting higher and higher. As an important bridge connecting the various links of production, sales and consumption, cold chain logistics is crucial to ensure the quality and safety of food, medicine and other temperature-sensitive items. Traditional refrigerators are highly dependent on electricity. Electricity is needed to maintain low temperatures during transportation, which leads to high costs and power outages that affect the refrigeration effect; traditional refrigerators using ice bags are generally small in size, and the ice bags have a general cooling effect. The existing cold-charging refrigerators are slow in the cold-charging process. When the number of refrigerators required is large, it takes a long time to charge the refrigerators in sequence. During the cold-charging process, the operator needs to charge a single refrigerator before charging the next refrigerator, which has low work efficiency; during the cold-charging process, the cold-charging amount cannot be accurately controlled, and over-charging is prone to occur. The actual amount of refrigerant charged for exchange is much higher than the theoretical value, which also leads to higher costs. Utility Model Content

[0005] The interlayer of the box body is isolated from the containing cavity of the box body, and the liquid storage component and the temperature measuring component are both arranged in the interlayer to avoid contamination of the objects to be refrigerated. Specifically, the liquid storage component includes a container or a pipe having a liquid inlet and a liquid outlet, and the first valve is respectively installed at the liquid inlet and the liquid outlet of the container or the pipe, that is, close to the position of the liquid inlet joint and the liquid outlet joint. When the first valve is closed, the refrigerant can be stored in the liquid storage component. The temperature measuring component is connected to the first valve signal. When the temperature measuring component detects that the temperature of the box body or the liquid storage component reaches the refrigeration temperature, the first valve is closed to prevent the refrigerant from continuing to be charged, thereby avoiding excessive use of the refrigerant and reducing costs. Furthermore, the temperature measuring component can be integrated with the first valve, that is, a temperature control valve is directly used. When the first valve close to the liquid outlet joint detects that the flowing refrigerant is the same temperature as the input refrigerant, the valve can be closed, which can also avoid excessive use of the refrigerant.

When charging is needed, the pump body is directly used to charge the refrigerant into the cold storage box, which can save the time required for refrigeration and further improve work efficiency.

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.
[0032] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:
[0033] Example 1
[0034] like Figure 2-4 As shown, the cold-filling refrigeration box includes: a box body 1, a liquid storage component and a temperature measuring component respectively connected to the box body 1, a valve component connected to the liquid storage component, and a liquid inlet connector 3 and a liquid outlet connector 4 respectively connected to the liquid storage component. The box body 1 is provided with an interlayer 101, and the liquid storage component and the temperature measuring component are both located in the interlayer 101. The valve component includes at least two first valves 5 installed on the liquid storage component, and the first valve 5 is an electrically controlled valve and is connected to the temperature measuring component signal. The liquid storage component is used to store a coolant, and the temperature measuring component is used to detect the real-time temperature of the box body 1 or the liquid storage component. The liquid inlet connector 3 and the liquid outlet connector 4 are respectively used to be connected to an external pipeline.
[0035] The interlayer 101 of the box body 1 is isolated from the receiving cavity of the box body 1. The liquid storage component and the temperature measuring component are both arranged in the interlayer 101 to avoid contamination of the objects to be refrigerated. Specifically, the liquid storage component includes a container or a pipe having a liquid inlet and a liquid outlet.

[0036] Beneficial effects of this embodiment: the first valve 5 is configured as an electrically controlled valve and is connected to the temperature measuring component signal, so that the valve can automatically close and stop cold charging after the cold charging is completed, thereby allowing the operator to connect and charge multiple cold storage boxes at the same time, which can greatly save the cold charging time and improve the cold charging efficiency. When there are many cold storage boxes, the operator does not need to wait for the current cold storage box to be charged before charging the next cold storage box, which saves the operator's waiting time, reduces the operator's work intensity, and improves work efficiency.
[0037] Example 2
[0038] like Figure 2-4 As shown, based on Example 1, the difference from Example 1 is that:
[0039] It also includes a phase change material piece arranged in the interlayer 101, and the phase change material piece is used to absorb the heat in the box body 1. The liquid storage assembly includes a liquid storage tube 2 arranged in the interlayer 101, and the liquid storage tube 2 is arranged in a circuitous manner and covers the four sides of the box body 1. The two ends of the liquid storage tube 2 are respectively connected to the liquid inlet joint 3 and the liquid outlet joint 4. The liquid inlet joint 3 and the liquid outlet joint 4 are both quick joints. The liquid storage assembly includes one or more liquid storage tubes 2 arranged in the interlayer 101. A box cover 102 is provided on the top of the box body 1, and a handle 103 is provided on the side of the box body 1.
[0040] The phase change material part contains phase change material, which is a commonly used heat-absorbing material in refrigeration equipment. It can also maintain a low temperature for a long time. When used with a liquid storage component, it can increase the refrigeration time of the box 1 and also improve the refrigeration effect. The liquid storage tube 2 is arranged in a circuitous manner, so that a single liquid storage tank can cover more area, and then the liquid storage tank covers the four sides of the box 1 to fully ensure the refrigeration effect. Specifically, an interlayer 101 is provided on all four sides of the box 1. The provision of a quick connector can increase the speed of connection and disassembly and improve work efficiency. Specifically, a gas-liquid common or liquid quick connector can be selected. The more liquid storage tubes 2 there are, the shorter the length of each liquid storage tube 2 is, and the faster the speed of cold filling is, which can further increase the cold filling speed. Both ends of each liquid storage tube 2 are respectively connected to a liquid inlet connector 3 and a liquid outlet connector 4.
[0041] The remaining features and working principles of this embodiment are consistent with those of Embodiment 1.
[0042] Example 3
[0043] like Figure 1-4 As shown, the utility model also provides a cold charging system, including the cold charging refrigerator of embodiment 1 or embodiment 2, and also including a cold supply component connected to the liquid outlet joint 4, a cold storage tank 6 connected to the cold supply component, and a pump body 7 connected to the cold storage tank 6, the pump body 7 is connected to the liquid inlet joint 3, the cold storage tank 6 is used to store a coolant, the cold supply component is used to cool the coolant, and the pump body 7 is used to quickly input the coolant into the liquid storage component. The cold supply component includes a heat exchanger 8 connected to the liquid outlet joint 4 and a refrigeration device 9 connected to the heat exchanger 8, and the coolant in the liquid storage component flows back to the heat exchanger 8 for cooling. It also includes a first pipeline 10, a second pipeline 11, a third pipeline 12, a second valve 13, a third valve 14 and a fourth valve 15. The pump body 7 is connected to the liquid inlet joint 3 through the first pipeline 10, the heat exchanger 8 is connected to the liquid outlet joint 4 through the second pipeline 11, the third pipeline 12 communicates with the first pipeline 10 and the second pipeline 11, the second valve 13 and the third valve 14 are respectively installed on the first pipeline 10 and the third pipeline 12, the second valve 13 is located between the third pipeline 12 and the liquid inlet joint 3, and the fourth valve 15 is installed on the second pipeline 11 and located between the third pipeline 12 and the liquid outlet joint 4. The second valve 13, the third valve 14 and the fourth valve 15 are all electrically controlled valves.
[0044] The liquid storage tank is used to store the refrigerant in advance. Before the refrigerator is charged with cold, the cold supply component is used in advance to cool the refrigerant, cool the refrigerant and then store it in the liquid storage tank. When charging with cold is needed, the pump body 7 is directly used to charge the refrigerant into the refrigerator, which can save the time required for refrigeration and further improve work efficiency. At the same time, using the pump body 7 to charge with cold can also increase the charging speed. Specifically, the refrigerant enters the cold storage tank 6 after the cold supply component cools down, and then enters the liquid storage component from the cold storage tank 6 through the pump body 7, the liquid inlet joint 3, and the first valve 5. The refrigerant in the liquid storage component passes through another first valve 5 and the liquid outlet joint 4 in turn and then enters the cold supply component.
[0045] The refrigeration equipment 9 provides a low-temperature liquid, and the low-temperature liquid exchanges heat with the refrigerant in the heat exchanger 8, thereby cooling the refrigerant. Specifically, the heat exchanger 8 is an evaporator or an evaporative condenser. Before charging, when the temperature of the refrigerant in the liquid storage tank is higher than the required temperature, the refrigerant in the liquid storage tank is transported to the heat exchanger 8 through the pump body 7 for cooling. Specifically, at this time, the second valve 13 and the fourth valve 15 are closed, and the third valve 14 is opened. The refrigerant flows through the first pipeline 10, the third pipeline 12, the third valve 14 and the second pipeline 11, and then enters the heat exchanger 8. Then the refrigeration equipment 9 cools the refrigerant, thereby fully utilizing the pump body 7 and reducing the equipment cost. When charging, the second valve 13 and the fourth valve 15 are opened, and the third valve 14 is closed. The first pipeline 10 and the second pipeline 11 are respectively connected with joints corresponding to the liquid inlet joint 3 and the liquid outlet joint 4. The second valve 13, the third valve 14 and the fourth valve 15 are set as electronically controlled valves, which can save operating steps and further improve work efficiency.
[0046] The rest of the working principle and working process of this embodiment are consistent with those of Embodiment 1 or Embodiment 2.
