Definitions

  • the present invention relates to a countercurrent heat exchanger for an electric vehicle heater.

  • the deflection region can be formed, for example, as a cap closing off the outer tube, so that the fluid in the second end region between the jacket flow space and the tube flow space is redirected in the radial direction and then flows back in the axial direction to the first end region, so that a "Countercurrent" arises in the heat exchanger.
  • the inner tube and the outer tube may be concentric with each other.
  • the first connection region with the first connection which can be designed, for example, as a simple connection piece, can be designed in particular as an annular transition space, through which the fluid is uniformly distributed on all sides of the inner tube between the jacket flow space, that of the inner tube and the outer Pipe is formed, and can even exceed the first connection area.
  • the second connection region with the second connection which can be designed as a simple connection piece, can be surrounded in an annular manner, for example, by the first connection region. It is conceivable, for example, that the second connection region represents an extension of the inner tube in the axial extension direction. Due to the design of the heat exchanger in the manner of a Jacobstromuzatäuschers a particularly compact design of the heat exchanger can be achieved.
  • the second port and the first port can be arranged together at an end portion of the heat exchanger, which allows particularly compact electric vehicle heaters, since the fluid circuit can be formed with small spatial dimensions.
  • the first port or the second port may be the inlet port, with the respective other port then being the outlet port.
  • the flow direction of the fluid within the Gegenstromebentäuschers changes depending on the port selected as the inlet port.
  • the electrical heating element arranged on the outer jacket surface of the outer tube can be, for example, a non-intrinsic heat conductor track, which can be applied to the outer jacket surface.
  • the electrical heating element can be applied to the outer circumferential surface by means of a plasma spraying method or by a thermal spraying method.
  • An electrically insulating separating layer can be applied between the electrical heating element and the outer jacket surface.
  • the electrical heating element may consist of a plurality of mutually independently controllable heating resistors, for example, a fine gradation to realize the registered in the heat exchanger heat output.
  • the electrical heating element can be covered to the outside to further improve the efficiency of the genstromstromebenleyers thermally insulating.

  • the jacket flow space is subdivided by at least two partition walls, wherein the at least two partition walls connect the inner tube and the outer tube perpendicular to the axial extension direction.
  • the at least two partition walls delimit flow components of the fluid flowing in the jacket flow space, which do not run parallel to the axial extension direction.
  • the at least two partitions also directly improve the heat input into the fluid, since they represent additional heat transfer surfaces and furthermore also produce a direct thermal bridge between the inner tube and the outer tube.
  • the at least two partitions may, for example, be produced together with the inner tube and the outer tube as a common and continuous extruded profile.
  • the inner tube and / or the outer tube are composed of at least two axial sections, which are rotated in the axial direction of extension against each other.
  • the at least two partitions interconnecting the inner tube and the outer tube perpendicular to the axial extension direction can form turbulence-promoting leading and trailing edges which promote mixing of the fluid within the heat exchanger.
  • the first connection is oriented perpendicular to the second connection. Due to the orientation of the second connection and the first connection, which is perpendicular to one another, the installation of the heat exchanger can be simplified, since the two connections are easier to reach with tools during assembly from different directions.
  • the outer circumferential surface of the outer tube has an at least partially planar surface.
  • the at least sectionally planar surface can lie, for example, in the first end region or in the second end region.
  • a control or power electronics can be arranged, which controls the electric heating element.

  • a turbulence-promoting surface structure may, for example, be a groove structure which reduces the thickness of the lamina boundary layer of the fluid flowing into the heat exchanger in the immediate vicinity of the respective surfaces of the inner or outer tube and, in particular, a vortex formation and / or promotes replacement.
  • the inner tube has ribs pointing radially inwards on an inner tube lateral surface. Ribs pointing radially inward on the inner tube lateral surface perform a similar function as the dividing walls between the outer tube and the inner tube.
  • a displacement body can be arranged in the interior of the inner tube.
  • the displacer in the interior of the inner tube may be hollow or solid, for example, with a hollow design being preferred because of the weight saved and the amount of inert thermal mass saved.

  • the electrical heating element is arranged by thermal spraying as a thermally sprayed layer on the outer circumferential surface of the outer tube. In this way, a uniform layer thickness of the heating element can be achieved. Furthermore, there is no need to fasten the electrical heating element with the aid of additional components, since even in the case of applications, a planar cohesive connection between the electrical heating element and the outer jacket surface of the outer tube results from the process.
