Abstract
A heat exchanger which may be continuously mass-produced by press-fitting heat exchange fins into refrigerant tubes and a manufacturing method thereof. The manufacturing method includes processing a metal sheet into a plurality of rows of heat exchange fins, transferring the plurality of rows of heat exchange fins through a transfer apparatus, dividing the plurality of rows of heat exchange fins into heat exchange fins in odd-numbered rows and heat exchange fins in even-numbered rows and integrating the heat exchange fins in odd-numbered rows and even-numbered rows through integration apparatuses, vertically standing and aligning the heat exchange fins in odd-numbered rows and even-numbered rows, separating the heat exchange fins in odd-numbered rows and even-numbered rows into a number of heat exchange fins, which may be simultaneously press-fitted into refrigerant tubes, through separation apparatuses, and press-fitting the separated heat exchange fins into the refrigerant tubes.
