Heat exchanger capable of dissipating heat through double sides and assembly method thereof

The invention belongs to the technical field of heat dissipation equipment, and particularly relates to a heat exchanger capable of dissipating heat through double sides. The heat exchanger comprisesa housing and fin assemblies, wherein the housing is divided into two cavities through a partition, wherein the two ends of each cavity are provided with openings, and two vent holes are separately formed in each cavity; the fin assemblies are mounted in the cavities; the fin assembly in each cavity separately communicates with the two vent holes to form a first air flue and a second air flue; andthe two fin assemblies' and the openings in the two ends of each cavity define a third air flue. The vent holes and the fin assemblies are arranged on the two cavities, and the vent holes and the finassemblies are in communication to form three air flues, so that double-sided heat dissipation of the heat exchanger can be effectively realized, and a great deal of heat dissipation space and production cost are saved.
