Abstract

See full text

A coaxial tube arrangement for a heat exchanger may include a coaxial tube and a closing cover. The coaxial tube may include an inner core channel and an outer annular channel. The closing cover may close the coaxial tube at a longitudinal end side. The closing cover may have a base region and a circumferential edge. The base region may be aligned transversely to a flow direction through the coaxial tube. The circumferential edge may be aligned with the flow direction and may face the coaxial tube. The circumferential edge may have a thickness, which is defined transversely to the flow direction, that is equal to or greater than a height of the annular channel, which is defined transversely to the flow direction. The circumferential edge may cover the annular channel transversely to the flow direction and may separate the annular channel from the core channel in a fluid-tight manner.
