Abstract
A heat exchanger includes: a first flow passage where first liquid flows; a second flow passage where second liquid flows; and a heat exchanger main body configured to exchange heat between the first liquid and the second liquid. The heat exchanger main body includes a cross-sectional area adjuster configured to change a flow passage cross-sectional area of at least one of the first flow passage and the second flow passage by thermal deformation. The cross-sectional area adjuster adjusts a value of the flow passage cross-sectional area in a low temperature range to be larger than a value of the flow passage cross-sectional area in a high temperature range.
