摘要： A heat exchanger has a flat tube (10) having a curved portion (13). A part of the curved portion (13) is formed by overlapping an outer rim (22) on an inner rim (21). The inner rim (21) has a small curvature region (102). The small curvature region (102) is inclined to a flat plate portion (11), and is defined by a radius larger than a difference between a half of a thickness of the flat tube (10) and a thickness of the outer rim (22). The small curvature region (102) is not beyond a center line (C1) in a thickness of the flat tube (10). The outer rim (22) extends beyond the center line (C1). The outer rim (22) has an end face (22a) placed on the small curvature region (102). The flat tube (10) has flared portions (15, 16) expanded at insertion holes (54).

摘要： A heat exchanger and a manufacture method thereof are provided. Before a tank body and a core plate of a header tank of the heat exchanger are fastened to each other, a gel seal material or a liquid seal material is applied to at least one of a seal surface of the core plate and that of the tank body and hardened. Thus, a seal member which adheres to the seal surface due to the tackiness of the seal member is formed. The core plate and the tank body are fastened to each other in such a state that the part between the seal surface of the core plate and that of the tank body are sealed by the seal member having been hardened. Accordingly, the seal member can be restricted of twisting and position-deviating when the core plate and the tank body are fastened to each other.
