Abstract
Disclosed is a parallel-flow heat exchanger with two rows of flat tubes. An upper header pipe is formed by covering an upper header pipe base with an upper header pipe cover plate. A lower header pipe is formed by covering a lower header pipe base with a lower header pipe cover plate. Two ends of two rows of flat tubes are plugged into flat-tube holes of the upper header pipe and the lower header pipe respectively. One of the two rows of flat tubes is used for communicating a buffer cavity with an overflow cavity, and the other one is used for communicating a return cavity with a confluence cavity. An inlet cavity is formed, on the lower header pipe base, in the buffer cavity, and is communicated with the buffer cavity through a plurality of jet holes formed in the wall thereof; an inlet pipe is connected to a port of the inlet cavity; an outlet pipe is arranged on a lower header pipe end plate at one end of the lower header pipe, and is communicated to the confluence cavity.
