摘要： The invention relates to a flat tube (1) for a heat exchanger. The flat tube (1) has two broad sites (2a, 2b) and two narrow sites (3a, 3b) which are connected to each other and delimit a flow space (4). The flow space (4) extends in a longitudinal direction (LR).
According to the invention, at least one barrel-shaped region (8) is formed on at least one of the broad sites (2a, 2b) of the flat tube (1). The barrel-shaped region (8) extends in the longitudinal direction (LR) and is convex transversely to the longitudinal direction (LR) and outwardly with respect to the flow space (4).
The invention also relates to a heat exchanger with the flat tube (1).-

摘要： The present invention relates to a heat exchanger (1) for media-separated heat transfer between a first fluid and a second fluid, having a heat exchanger block (2) which has a plurality of tubes (6) through which the first fluid can flow, a plurality of interstices (7) through which the second fluid can flow being formed on the heat exchanger block (2), each interstice (7) being located between two adjacent tubes (6), the heat exchanger block (2) having a head shell (9) at each of its longitudinal block ends (3), which extend parallel to the block transverse direction (Y), are penetrated by the tubes (6), are soldered to the tubes (6) and in each case have two shell transverse ends (10) facing away from one another in the block transverse direction (Y), the heat exchanger block (2) having a cover plate (11) at each of its block transverse ends (4), which extend parallel to the block longitudinal direction (X), are brazed to the head shells (9) and each have two plate longitudinal ends (12) facing away from one another in the block longitudinal direction (X).
The manufacture of the heat exchanger (1) is simplified if the heat exchanger block (2) has four anchorages (13), each of which positively connects one of the longitudinal plate ends (12) directly to one of the transverse shell ends (10).
