A filter arrangement may include a filter element and a gasket element. The gasket element may include a substantially circular flow-through opening and a locking collar. The locking collar may be arranged along a circumference of the flow-through opening with respect to a circumferential direction. The locking collar may form a hollow cylindrical installation space. The filter element may include a filter element body and a substantially hollow-cylindrical counter locking collar. The counter locking collar may include an open axial side and a covered axial side which may be spaced apart from each other with respect to an axial axis. The covered axial side of the counter locking collar may be covered by said filter element body. The counter locking collar may be at least partially inserted into the hollow cylindrical installation space of the locking collar.

Filter arrangement

A Peltier element for a thermoelectric heat exchanger may include n-doped n-type semiconductors, p-doped p-type semiconductors, and a plate structure for electrically contacting the semiconductors. The plate structure may include first plate sections and second plate sections, which may be alternately arranged along an extension of the Peltier element. The first plate sections may form a first side of the Peltier element, and the second plate sections may form a second side of the Peltier element, the second side being spaced from the first side. The plate structure may further include a plurality of legs. Each leg may interconnect adjacent first and second plate sections and may extend inclined relative to the adjacent first and second plate sections. An n-type semiconductor and a p-type semiconductor may be alternately integrated in the legs along the plate structure.

Peltier-element

A method for producing a Peltier element of a heat exchanger for temperature control of a fluid flowable through a flow chamber may include providing an electrically conductive belt. The method may also include providing the belt with a plurality of p-doped P-semiconductors and a plurality of n-doped N-semiconductors so as to alternate with one another along the belt. The plurality of p-doped P-semiconductors and the plurality of n-doped N-semiconductors respectively may have a side facing away from the flow chamber electrically contacted by a contacting structure that may include a plurality of contact elements. The method may also include separating the belt to produce a plurality of connecting elements of a connecting structure electrically contacting a side of the plurality of p-doped P-semiconductors and the plurality of n-doped N-semiconductors facing towards the flow chamber, respectively.

Thermoelectric heat exchanger

A thermoelectric arrangement for use in a cooling system () of a motor vehicle has a thermocouple () with a first, heat-outputting thermal element (), a second, heat-absorbing thermal element () and a conductor element () through which current flows. At least two cooling circuits () are provided. The first thermal element () is arranged in at least one cooling circuit (), and the second thermal element () is arranged in at least one heating circuit (). The first thermal element () is arranged in a first connecting line () that is connected fluidically to the respective cooling circuits () via valve arrangements () on the input and output sides of the first thermal element (). A cooling system having such a thermoelectric arrangement also is described.
