The fluid connector assembly includes a connector body with an intermediate portion that extends between opposite end portions and has a first bore. The connector body has an elongated wall that projects outwardly from the intermediate portion and that surrounds a second bore which opens to the first bore. A flat tube, which is made of a second material that is different than the first material and has at least one fluid passage, is in fluid communication with the second bore of the connector body. The flat tube has generally flat side walls and is lockingly retained with the connector body by male and female locking structures that cooperate with one another.

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.
