As shown in fig. 1 and 2, the present invention provides a refrigerating apparatus including a storage container 100 and a cooling device 200.

The storage container 100 is provided therein with a storage cavity 131 for placing an article to be refrigerated, and a cooling structure 140 for cooling the article in the storage cavity 131 and maintaining a low temperature. The cold carrying structure 140 is adjacent to the storage chamber 131 so as to facilitate the transfer of cold.

The cold-carrying structure 140 has therein a cold-carrying agent, the cold-carrying agent is a liquid capable of transferring cold, the cold-carrying agent can be one or a mixture of brine, ethylene glycol and an anti-freezing solution, and the freezing point of the cold-carrying agent is lower than-40 ℃ and the boiling point of the cold-carrying agent is higher than 80 ℃.

The cooling device 200 includes a cold end. The cold end has a first state that extends into the interior of the cold-carrying structure 140 or is attached to the cold-carrying structure 140, and a second state that is separated from the cold-carrying structure 140.

The cold end is a part for providing cold in the cold supply device 200, and may be a semiconductor wafer or an evaporator 240. When the cold side is a semiconductor wafer, the first state of the cold side is a bonded cold carrying structure 140. When the cold end is the evaporator 240, the first state of the cold end may be inside the cold-carrying structure 140 or may be attached to the cold-carrying structure 140.

The cold carrying structure 140 cools the articles in the storage chamber 131, and when the cold end is in the first state, the cold supply device 200 supplies cold to the cold carrying structure 140 to perform cold charging operation. When the cold end is in the second state, the cold end is separated from the cold-carrying structure 140, the storage container 100 is convenient to transport and transport, and the coolant inside the cold-carrying structure 140 can maintain the temperature of the storage container 100, thereby continuously refrigerating the articles in the storage cavity 131.

Moreover, because the secondary refrigerant is positioned in the secondary cooling structure 140, the secondary refrigerant does not directly contact with the articles in the storage cavity 131, and the influence of slight corrosivity and slight toxicity of the secondary refrigerant on the safety of the articles is avoided.

When the cold-carrying structure 140 in the storage container 100 needs to be charged with cold, the cold end of the cold supply device 200 extends into the storage container 100 to refrigerate the secondary refrigerant in the cold-carrying structure 140, the secondary refrigerant has no leakage risk in the cold charging process, the safety performance of the refrigeration device is improved, and the loss of cold energy in the cold charging process is small.

The refrigeration process of the refrigeration loop is as follows: after being compressed into high-temperature and high-pressure gas by the compressor 210, the refrigerant enters the condenser 220 to exchange heat to form a liquid refrigerant with medium temperature and high pressure. The liquid refrigerant passes through the capillary tube 230, is throttled and depressurized, then enters the evaporator 240 to be subjected to heat exchange and gasification, and finally the gaseous refrigerant returns to the compressor 210 to complete the refrigeration cycle. The evaporator 240 forms the cold end and, when the cold end is in the first state, the evaporator 240 is positioned within the cold carrier structure 140 to refrigerate the coolant within the cold carrier structure 140.

When the cold end is in the first state, the circulation pump 250 extends into the cold carrier structure 140. The circulation pump 250 selects a diaphragm pump that can sink into the liquid. The circulation pump 250 can circulate the coolant within the coolant structure 140 to equalize the coolant temperature and enhance heat exchange with the evaporator 240.

As shown in fig. 5, the condensing fan 260 is disposed at a side of the condenser 220, and functions to dissipate heat of the condenser 220.

The circulation pump 250 and the evaporator 240 are mounted on the evaporator support 290. The circulation pump 250 and the evaporator 240 move up and down during the rotation of the evaporator support 290. When a user needs to charge the cold loading structure 140 with cold, the circulation pump 250 and the evaporator 240 are located at the high point of their travel, the cooling device 200 is pushed, the cooling device 200 is moved laterally to be close to the storage container 100 by the casters, and finally the evaporator support 290 is rotated, so that the circulation pump 250 and the evaporator 240 move downward to enter the interior of the cold loading structure 140.

A hollow area 2911 is formed in the middle of the frame 291, the evaporator 240 is a coil type, a part of the evaporator 240 corresponds to the hollow area 2911, and a solid part of the frame 291 is used for fixing the evaporator 240. The hollowed-out region 2911 of the frame 291 increases the exposed area of the evaporator 240. When the evaporator 240 sinks into the coolant, both sides of the evaporator 240 can supply the coolant, thereby improving the cooling uniformity and the cooling effect.

The support plate 292 is used to mount the circulation pump 250. In order to improve the stability of the cooling device 200, the support plate 292 extends in a direction perpendicular to the frame 291, and the evaporator 240 is installed at a side of the frame 291 facing away from the support plate 292, ensuring that the center of gravity of the evaporator 240, the circulation pump 250, and the evaporator support 290 is not eccentric.

Further, the inlet end of the evaporator 240 is connected to the capillary tube 230, the outlet end is connected to the bellows 241, and the capillary tube 230 and the bellows 241 are pivotally connected to the evaporator support 290 and the pipeline support 280. In the rotation process of the evaporator bracket 290 relative to the pipe bracket 280, the capillary tube 230 and the corrugated pipe 241 prevent the pipe from being damaged by their own expansion and contraction, thereby preventing the refrigerant from leaking and improving the safety performance.

The cold accumulation structure 150 is filled with a cold accumulation agent, and the cold accumulation agent is water or other liquid materials with high specific heat and solidification temperature higher than that of the secondary refrigerant. The storage structure can absorb and store cold energy by utilizing phase change. Specifically, after the cold storage agent in the cold storage structure 150 absorbs the cold of the cold carrying structure 140, the cold storage agent is frozen. After the box body 110 is opened, the storage cavity 131 and the cold-carrying structure 140 are heated, at the moment, the cold storage agent is liquefied, the cold energy of the storage cavity 131 and the cold-carrying structure 140 is absorbed, the problem that the temperature of the cold-carrying agent is raised back after the temperature of the articles is lowered can be effectively avoided, and therefore the articles are cooled for many times. When the cold storage agent is completely liquefied, the cold energy accumulated by the cold storage structure 150 is completely dissipated, and at the moment, the cold end supplies cold to the cold carrying structure 140, so that the cold storage agent is cooled and frozen, and the cold storage structure 150 accumulates the cold energy again.
