Abstract
In a heat exchanger (1) including first through M-th tube groups, each tube group comprising at least one exchanger tube (10), and a distribution device (3) which has a distribution tank (30) supplied with a medium and first through M-th distribution paths (31, 32, and 33) for directing the medium from the distribution tank to the first through the M-th tube groups, respectively, medium inlet ports of the first through the M-th distribution paths are coupled to first through M-th regions of the distribution tank that have first through M-th void ratios different to each other. Medium outlet ports of the first through the M-th distribution paths are coupled to the exchanger tubes of the first through the M-th tube groups, respectively. The number of the exchanger tubes of each of the first through the M-th tube groups and an inner cross-sectional area of each of the first through the M-th distribution paths are defined on the basis of the first through the M-th void ratios of the first through the M-th regions of the distribution tank so that a mass flow of the medium introduced into one of the exchanger tubes of the first through the M-th tube groups is substantially equal to the m…
