摘要： A coaxial tube arrangement for a heat exchanger is disclosed. The coaxial tube arrangement includes a coaxial tube and a closing cover. The coaxial tube includes an outer wall with a plurality of nubs. The closing cover closes the coaxial tube at a longitudinal end side. The closing cover has a base region and a circumferential edge. The base region is aligned transversely to a flow direction through the coaxial tube. The circumferential edge is aligned with the flow direction and faces the coaxial tube. The circumferential edge covers the annular channel transversely to the flow direction and separates the annular channel from the core channel in a fluid-tight manner.

摘要： A stacked plate heat exchanger for a motor vehicle may include a plurality of elongated plates stacked on one another between which a plurality of cavities are disposed alternately for two media. The plurality of cavities may be respectively delimited by a respective plate of the plurality of plates zonally by a plate surface and a surrounding wall. The respective plate may include two flow openings, two passage openings, and two domes respectively arranged around one of the two passage openings. At least of one of the plurality of plates may further include an elongated separation shaping arranged on the plate surface, projecting into the respective cavity, and extending from the first short side between the two flow openings in a direction of the second short side. The separation shaping may adjoin the first short side at an angle α of 45° to 90°.

摘要： 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.

摘要： A stacked disc heat exchanger for a thermal management module may include a plurality of stacked discs arranged following one another in a stacking direction. Each stacked disc of the plurality of stacked discs may include a bottom extending transversely to the stacking direction. An outermost disc of the plurality of stacked discs in the stacking direction defining a cover disc. The cover disc may include at least one convexity formed in the stacking direction towards an outside. The at least one convexity may extend transversely to the stacking direction and may form a channel for a flow path extending through the stacked disc heat exchanger of a fluid. The cover disc may further include at least one opening that is open in the stacking direction towards the outside for fluidic connection with the thermal management module.

摘要： A liner tube for an inlet channel of a plate heat exchanger may include an open front side for supplying a refrigerant mass flow, an at least partially closed rear side, and at least two bag-like chambers running in a longitudinal direction of the liner tube. Each chamber may communicate with the open front side, and may have openings at chamber-dependent different positions for distributing the refrigerant mass flow in plate stacks of the plate heat exchanger.

摘要： A heat exchanger or chiller may include a heat exchanger block having a first fluid channel for a coolant and a second fluid channel for a refrigerant, an expansion valve for controlling a mass flow rate of the refrigerant, and a connection flange having an inlet channel and an outlet channel for the refrigerant. The expansion valve may be designed as an electronic expansion valve. The inlet channel may be connected to the second fluid channel in a transition region of the inlet channel. The connection flange may have an insertion opening, which may communicate with the transition region of the inlet channel, and into which the expansion valve may be inserted such that the expansion valve may control the mass flow rate of the refrigerant in the transition region and evaporation of the refrigerant may first occur in the second fluid channel.

摘要： A thermal management module for a thermal management system is disclosed. The thermal management module includes a first heat exchanger for flowing through by a refrigerant and by a working medium fluidically separately with respect to the refrigerant. A second heat exchanger is provided including at least a first fluid path and at least a second fluid path, separate from the first fluid path, respectively for flowing through by the refrigerant. A connecting arrangement is arranged between the first heat exchanger and the second heat exchanger. The connecting arrangement connects the first heat exchanger and the second heat exchanger to one another mechanically and fluidically, so that the refrigerant can flow between the first heat exchanger and the second heat exchanger.
