According to the invention, the shell 1 is divided into two cavities 11 with two open ends, and the first air duct 4, the second air duct 5 and the third air duct 6 are respectively formed by the vent 111 on the cavity 11 and the two fin assemblies 2, so that double-sided heat dissipation of the heat exchanger is realized, the heat dissipation space is effectively reduced, and the production cost is greatly saved.
