Side ventilation grooves 19 are opened on both sides of the shell 1.

[0024] One end of the pipeline 2 is connected to a second liquid inlet pipe 5 through a connecting pipe 6. The second liquid inlet pipe 5 is set to an L shape. The bottom of the second liquid inlet pipe 5 is connected to a buffer mechanism 10. The bottom of the buffer mechanism 10 is connected to the top of the first liquid inlet pipe 4.

Thereafter, the refrigerant slowly enters the U-shaped second liquid inlet pipe 5 through the equal gaps between the circular hemisphere 13 and the spherical shell 11, and then enters the pipeline 2 through the connecting pipe 6. The evaporator has a buffer structure when the refrigerant enters, which can improve the uniformity of the refrigerant entering the evaporator and prevent it from affecting the working effect of the air conditioner.
