REFRIGERANT GUIDING PIPE AND HEAT EXCHANGER HAVING IT

摘要

Disclosed is a refrigerant guiding pipe (10) which comprises a pipe wall (17) forming an internal cavity (19), openings (11a) formed in the pipe wall (17) and refrigerant guiding wall parts. At least a part of the edge of the refrigerant guiding wall part is separated from the pipe wall (17) so as to form the opening (11a). The refrigerant guiding pipe (10) can decrease uneven distribution of the refrigerant caused by the layer separation of gas and liquid.
