Refrigerated container device

Abstract

The invention provides a refrigerated container device which comprises a refrigeration part, a refrigerant guiding part, a secondary refrigerant pump and a refrigerated container body. The refrigeration part is used for generating the refrigerating capacity and comprises at least two symmetrically-arranged refrigerators. The two sides of the refrigerant guiding part are connected with the refrigerators correspondingly, and a secondary refrigerant for taking away the refrigerating capacity circulates in the refrigerant guiding part. The secondary refrigerant pump communicates with one end of the refrigerant guiding part and is used for supplying the secondary refrigerant. The refrigerated container body comprises a containing cavity and a sinuous coil, the containing cavity is used for containing a to-be-refrigerated object, and the sinuous coil allows the secondary refrigerant to flow to supply the refrigerating capacity to the to-be-refrigerated object. The refrigerant guiding part comprises a refrigerant guiding shell, a refrigerant guiding unit, a plurality of sets of refrigerant guiding channels, a liquid distributing groove and a liquid convergence groove. The two sides of therefrigerant guiding shell are connected with the two refrigerators correspondingly, and the refrigerant guiding unit is arranged in the refrigerant guiding shell and makes contact with the sterling refrigerators to take away the refrigerating capacity. The multiple sets of refrigerant guiding channels are formed in a refrigerant guiding cavity to be surrounded by refrigerant guiding blocks, one ends of the refrigerant guiding channels communicate with the liquid distributing groove, and the other ends of the refrigerant guiding channels communicate with the sinuous coil in the refrigerated container body. The refrigerating capacity is transmitted into the refrigerated container body.

Description

technical field [0001] The invention relates to the technical field of refrigeration and refrigeration, in particular to a refrigerator device. Background technique [0002] In recent years, with the rapid development of biology, pharmacy, medical and other fields, the demand for low-temperature refrigerators has been increasing year by year. As a small low-temperature regenerative refrigerator, the Stirling refrigerator has the characteristics of high efficiency at low temperature, no refrigerant pollution, wide cooling temperature range, low starting current, and easy adjustment of cooling capacity, so it is used as a small-capacity low-temperature refrigeration The cold source of the box has considerable advantages. [0003] However, in the mobile cold chain box in the prior art, a cold end adapter is provided outside the cold end of the Stirling refrigerator, and the cold end adapter is combined with the cold guide tube to transfer the cold energy of the Stirling refrig...

[0003] However, in the mobile cold chain box in the prior art, a cold end adapter is provided outside the cold end of the Stirling refrigerator, and the cold end adapter is combined with the cold guide tube to transfer the cold energy of the Stirling refrigerator to the inside of the box. , the disadvantage of such a device is that the contact area between the cold guide tube and the cold end adapter is too small, which will lead to insufficient condensation of the working medium in the cold guide tube and poor cooling performance; in addition, a single Stirling refrigerator is used as a cold The cold source of the chain box must be equipped with a shock absorber to absorb the vibration of the refrigerator during operation. Usually, the mass of the shock absorber is 0.1 to 0.3 times the mass of the Stirling refrigerator, so that the mass of the whole machine increases and increases The quality of the Stirling refrigerator does not increase the cooling capacity of the Stirling refrigerator, and the cooling capacity of the refrigerator of the same quality is reduced
