Abstract (en)
[origin: EP4067805A1] The present invention provides a heat exchanger (100) and a refrigeration system (1000). The heat exchanger (100) includes a collecting pipe (10), and the collecting pipe (10) includes a plurality of pipe units (13). The plurality of pipe units (13) are sequentially stacked and connected, and each of the plurality of pipe units (13) includes a first section (131) and a second section (132). A diameter of the first section (131) is less than that of the second section (132), such that the first section (131) of one of adjacent two of the plurality of pipe units (13) is capable of inserting into the second section (132) of the other of adjacent two of the plurality of pipe units (13). An arc-shaped section (133) is provided between the first section (131) and the second section (132) of each of the plurality of pipe units (13), and the arc-shaped section (133) extends to a top of the second section (132) from a bottom of the first section (131), so that the first section (131) is connected to the second section (132).
