1. A heat exchanger comprising:
a header tank including a plurality of flow paths through which a heat exchange medium flows;
multiple rows of tubes connected to the header tank; and
a heat radiation fin interposed between the tubes,
wherein the tube includes a heat exchange part coupled to the heat radiation fin and a coupling part positioned at a longitudinal end of the heat exchange part to be coupled to the header tank, and the coupling part has a width less than a width of the heat exchange part,
wherein the header tank includes:
the flow paths positioned independently from each other by a partition positioned in the header tank,
a header including multiple rows of tube insertion holes into which the tube is inserted;
a tank coupled to the header to have a space in which the heat exchange medium flows; and
a partition coupled to the header and the tank to partition the inner space of the tank,
wherein the coupling part of the tube is inserted and coupled to the tube insertion hole,
wherein the partition is integral with the tank, and further includes a gasket interposed between an end of the partition and the header,
wherein a width A of the coupling part of the tube satisfies Equation 1 below:
A=(D−W)±1.0 (Equation 1)
wherein D is a width of heat exchange part, and W is a transverse width of gasket interposed between end of partition and header.
