The refrigeration system according to the embodiment of the present invention is described in detail below with reference to Fig. 1 and Fig. 2.
As depicted in figs. 1 and 2, the refrigeration system of embodiment according to a first aspect of the present invention, comprises evaporator tube 1 and capillary 2.
Specifically, capillary 2 is connected with evaporator tube 1, and one end that evaporator tube 1 is connected with capillary 2 is the entrance point of evaporator tube 1, and the low temperature refrigerant in capillary 2 is flowed in evaporator tube 1 by the entrance point of evaporator tube 1.Because the caliber of capillary 2 is very little, the caliber of evaporator tube 1 is comparatively large, and when the low temperature refrigerant in capillary 2 flows in evaporator tube 1, because caliber becomes large, the pressure of refrigerant reduces, gasification heat absorption in the flow process of refrigerant in evaporator tube 1, thus realizes refrigeration.Now, the temperature of the entrance point of evaporator tube 1 is evaporating temperature, and evaporating temperature is lower, and the cryogenic temperature that can realize is lower.
The entrance point being wrapped in evaporator tube 1 at least partially of capillary 2, the refrigerant that can extend in capillary 2 flows through the time of the entrance point of evaporator tube 1 thus, also just can lower the temperature to the entrance point of evaporator tube 1, namely the temperature of the entrance point of evaporator tube 1 can be made to drop to lower, thus it is lower that evaporating temperature can be made to drop to, and then cryogenic temperature can be made to reach lower.Need here to illustrate, in capillary 2, flowing is low temperature refrigerant, and the temperature of capillary 2 is lower, and the temperature of evaporator tube 1 wants high relative to the temperature of capillary 2.Therefore, when the low temperature refrigerant in capillary 2 flows into the entrance point of evaporator tube 1 from capillary 2, the capillary 2 that the entrance point place of evaporator tube 1 is wound around can be lowered the temperature to the entrance point of evaporator tube 1.
According to the refrigeration system of the embodiment of the present invention, by the entrance point being wrapped in evaporator tube 1 at least partially by capillary 2, the entrance point of capillary 2 pairs of evaporator tubes 1 can be made thus to lower the temperature, thus the temperature of the entrance point of evaporator tube 1 can be reduced further, and then cryogenic temperature can be made to reach lower.
Further, also comprise compressor (scheming not shown) and condenser (scheming not shown) according to the refrigeration system of the embodiment of the present invention, compressor, condenser, capillary 2 and evaporator tube 1 are connected to form refrigerating circuit successively.Refrigerant in refrigeration system becomes high pressure refrigerant by compressor compresses, high pressure refrigerant to flow in condenser and carries out heat exchange with condenser, the heat release of high pressure refrigerant is liquefied as liquid high pressure refrigerant, liquid high pressure refrigerant is by flowing in evaporator tube 1 after capillary 2 reducing pressure by regulating flow, refrigerant is endothermic gasification in evaporator tube 1, temperature around evaporator tube 1 is reduced, thus refrigeration can be realized.Refrigerant after gasification flows in compressor and compresses, and then carries out above-mentioned refrigerant circulation utilization, thus can realize the continuous firing of refrigeration system.
According to some embodiments of the present invention, shown in Fig. 1 composition graphs 2, evaporator tube 1 comprises tube body 11 and reducing pipe portion 12.The one end 121 (lower end with reference in Fig. 1) in reducing pipe portion 12 is connected with the import of tube body 11, and the other end 122 (upper end with reference in Fig. 1) in reducing pipe portion 12 reduces gradually towards (in reference Fig. 1 direction) upwards caliber on the direction away from the import of tube body 11 and connects capillary 2.Now, the other end 122 be connected with capillary 2 in reducing pipe portion 12 is the above-mentioned entrance point of evaporator tube 1.Thus, the caliber of the entrance point of evaporator tube 1 is less, the entrance point of evaporator tube 1 can become a changeover portion of the very little capillary of caliber 2 evaporator tube 1 larger with caliber, thus the low temperature refrigerant in capillary 2 can be made to be entered into reposefully in evaporator tube 1 by above-mentioned changeover portion.Alternatively, capillary 2 is welded to connect with the reducing pipe portion 12 of evaporator tube 1, and reducing pipe portion 12 can weld with tube body 11 or one-body molded.
