Abstract
A heat exchangerincludes at least a plurality of tubesand an upper tankcommunicating with an upper end portion of a tube group formed by the tubesso as to distribute coolant along the up/down direction. The coolant flows in through an inflow portlocated at the upper tankin the heat exchanger. An open-top coolant intake guide passageis disposed at the inflow portand the coolant intake guide passageis thus inserted at the upper tank. With this configuration, coolant flowing at a very low flow rate has improved distribution, and uniformity in the output air temperature is achieved, while ensuring that the structure does not create excessive resistance against the coolant flow at a high flow rate.
