WIPO Patent Application WO/2020/090377
Kind Code:
A1
Abstract:
A heat exchanger (10) according to the present invention is provided with a plurality of tubes (21), a cylindrical first tank (30) and a cylindrical second tank (40). A coolant flows through a first internal channel of the first tank, a first tube (21a), the second tank, a second tube (21b) and a second internal channel of the first tank in this order. The second tank is internally provided with a channel formation part (41) where a coolant channel (410), which has a cross-sectional area that is smaller than the cross-sectional area of an internal channel of the second tank in a cross section that is perpendicular to the longitudinal direction of the second tank, is formed. The coolant channel is arranged so that the projection area thereof overlaps with the tubes when viewed from the longitudinal direction of the second tank.
