Abstract
A core unitof a heat exchanger includes a plurality of core plates that are stacked on one another to alternately constitute oil passagesand cooling water passagesin which oil that is heat-exchanged in the core unitis guided to an outlet portafter passing through a top connecting passageand an oil outlet passage Land in which part of the oil is led from a lower end of an upper/lower oil passage Lis guided to the outlet portthrough an auxiliary passageso that the amount of oil flowing in the oil outlet passage Lis reduced thereby reducing a passage resistance.
