Evaporator and refrigerator

The invention provides an evaporator and a refrigerator. The evaporator comprises a refrigerant pipeline; and the vortex generating device is arranged in the refrigerant pipeline and is configured to enable the refrigerant flowing through the vortex generating device to generate vortex flow. According to the evaporator, the vortex generating device is arranged in the refrigerant pipeline to enable the refrigerant flowing through the vortex generating device to flow in a vortex shape, so that the flow state of the refrigerant in the refrigerant pipeline can be changed, and a boundary layer between the refrigerant and the inner wall of the refrigerant pipeline can be effectively reduced or even eliminated; the refrigerant can be better attached to the inner wall of the refrigerant pipeline for heat exchange, the flow speed of the refrigerant can be increased, and therefore the purpose of enhancing the internal heat exchange capacity of the evaporator is achieved. 本发明提供了一种蒸发器及冰箱，蒸发器包括：制冷剂管路；和涡流发生装置，设置于所述制冷剂管路内，配
