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. As refrigerant flows through the heat exchange flat tubes twice fully, flowing resistance is low, flow channel is long, eddy is not easy to generate along the flow channel, sufficient heat exchanging of the parallel-flow heat exchanger with two rows of flat tubes is achieved, heat exchange efficiency is high, and the energy efficiency ratio of an air-conditioner device with the heat exchanger can be increased. In addition, the parallel-flow heat exchanger with two rows of flat tubes is simple in integral structure, easy to manufacture and convenient to mount.
