Abstract
A heat exchanger includes aligned tubes and upper and lower header tank units, each of which includes two fluid conduits communicated with the tubes. Each header tank unit further includes an intermediate plate, which defines a plurality of communication holes therethrough. Each communication hole communicates between a corresponding one of the tubes and a corresponding one of chambers defined by the fluid conduits of the header tank unit such that each tube is spaced apart from the corresponding one of the chambers.
