Abstract:
1. A heat exchanger comprising: a pair of header tanks spaced apart from each other by a predetermined interval and arranged at upper and lower parts parallel to each other; a plurality of tubes combined to both ends of the header tanks in such a way as to fluidically communicate with the header tanks; radiation fins interposed between the tubes; and a pair of side supports mounted at the outermost ends of the tubes and the radiation fins to protect the tubes and radiation fins, one of the side supports having a body combined to the header tanks and ribs bent at both sides of the body in U-shape to reinforce strength and form bonding surfaces of sealing members and the ribs being protrudingly formed in an outward direction of the body; wherein when a width of at least one of the side supports is Ws, a width (B) of the ribs formed on the body satisfies the following formula in order for the ribs to have inner space in the U-shape thereof: wherein outside walls of the U-shaped ribs are formed as free ends and wherein the edges of the free ends of outside walls of the U-shaped ribs press the end of the edges of the radiation fins.
