  • Publication number: 20210247149
    Abstract: An inner rib, in particular for a flat tube, in particular of a heat exchanger, made from a metallic flat strip, which is shaped in a wavy modulated manner, having a large number of wave crests and wave troughs, which are each arranged alternately in a longitudinal direction of the inner fin, an essentially straight, web-like fin area being provided between one wave crest and an adjacent wave trough and connecting the wave crest to the wave trough, the metallic flat strip having a first strip thickness L1, which is essentially constant in the area of the wave crests and the wave troughs, the flat metallic strip having a second strip thickness L2, which is provided in the area of the web-like fin area, L2 being smaller than L1.

  • Patent number: 9863663
    Abstract: Disclosed herein is a heat exchanger, comprising at least one electric resistance heating element, at least two conductors which are connected to the at least one electric resistance heating element in an electrically conductive manner in order to conduct electric current through the at least one electric resistance heating element and thereby heat the electric resistance heating element, at least one thermally conductive element for transferring heat from the at least one electric resistance heating element to a fluid to be heated, at least one electrically insulating element, which electrically insulates the at least two conductors, and at least one pipe, wherein the at least two conductors and the at least one electric resistance heating element are arranged within a cavity bounded by the pipe and the pipe lies on the at least one electrically insulating element under a compressive force at at least one contact surface.
