Heat exchanger and cooling apparatus mounted with the same

摘要

An object of the invention is to settle an unbalanced refrigerant flow in a heat exchanger thereby to improve a heat exchanging efficiency. In a heat exchanger having a refrigerant conduit provided through a plurality of fins, the refrigerant conduit is divided into a plurality of sets, each consisting of a plurality of parallel conduits, and parallel conduits of a set are put in communication with each other at ends thereof and in communication, through a single passage, with ends of parallel conduits of another set.
