Abstract
A refrigerant guiding pipe has a pipe wall in which an inner chamber is formed; an opening formed in the pipe wall; and a refrigerant guiding wall portion, at least a part of an edge of the refrigerant guiding wall portion being separated from the pipe wall, thereby forming the opening. The refrigerant guiding pipe can help alleviate generation of non-uniform distribution of refrigerant due to layering of gaseous refrigerant and liquid refrigerant.
