Abstract
The present invention relates to the field of printed circuit heat exchangers, and in particular, to a modular square-circular composite channel printed circuit heat exchanger. The modular square-circular composite channel printed circuit heat exchanger comprises a shell, wherein the shell is divided into an inlet diverter section, a first parallel heat exchange section, a core heat exchange section, a second parallel heat exchange section, and an outlet combiner section from left to right, a plurality of square fin channels and circular micro-channels are uniformly arranged in the shell along a length direction of the shell. According to the present invention, a ratio of an average thermal resistance of a hot side to an average thermal resistance of a cold side is close to 1, which ensures the heat exchange efficiency while taking into the account structure safety and prevents the local over-temperature.
