Since the buffer cavity is wide at the top and narrow at the bottom, the refrigerant first enters the wider cavity for buffering, and then enters the flow cavity through the narrower cavity, and then enters the throttling cavity through the flow cavity for preliminary throttling. When the refrigerant fills the throttling cavity, it enters the liquid outlet pipe. The throttling part arranged on the liquid outlet pipe facilitates further throttling of the refrigerant. The liquid distributor is equipped with multiple throttling structures when in use, which can effectively improve the throttling effect. The refrigerator enters each capillary tube evenly, and will not affect the refrigeration effect.

[0009] Specifically, a sealing ring is provided on the periphery of the liquid inlet pipe near the upper end of the connecting plate, and the sealing ring is in contact with the inner wall of the through groove.
[0010] Specifically, an annular protrusion is arranged on the periphery of the shell, a reserved groove is penetrated through one side of the vertical plate, and the annular protrusion is welded in the corresponding reserved groove.
[0011] By adopting the above technical solution, the annular protrusion can be conveniently arranged through the vertical plate and the reserved groove, and when the vertical plate is fixed, the annular protrusion and the shell can also be fixed.
