A heat exchanger is provided to reserve a clad material molten solution, which is generated in the process of manufacturing the heat exchanger, in flow preventing parts to prevent the solution from being introduced into heating fins, thereby protecting the heating fins. A heat exchanger includes a support(40) having a header(20) contacting end with a predetermined radius of curvature(R2) which is larger than that(R1) of the header, so that flow preventing parts(42) are naturally formed in a joining part(41) between the support and the header when the support is coupled to the header. The flow preventing parts prevents a clad material molten solution from overflowing along the joining part but received in the flow preventing parts, so as to prevent the clad material molten solution from damage to heating fins. |
