Abstract: A burner (10), particularly for vehicle heaters, includes a flexible panel (12) that separates an inner combustion region (14) from an outer region (16). A light-sensitive sensor for flame recognition is arranged in the outer region (16), and the flexible panel (12) includes at least one light opening (20) that allows the passage of light from the inner combustion region (14) into the outer region (16). The light opening (20) also allows the passage of combustion air from the outer region (16) into the inner combustion region (14).

Abstract: An electric heating appliance, particularly a liquid or air heating appliance, particularly for a motor vehicle, comprising a first heating element with a corresponding main body and at least one second heating element with a corresponding main body. A clearance is formed between the heating elements through which fluid can flow for its heating. The heating elements are joined together by at least one spacer arranged between them, particularly a conductive spacer. The spacer is a fixed component of the first heating element.

Abstract: A heat exchanger and a method of manufacturing a heat exchanger having an internal conduit for conducting a fluid, and a heat dissipating body for dissipating heat of the fluid. The heat dissipating body has a cavity extending in a longitudinal direction. An end piece of the internal conduit extends inside of the cavity and has an orifice facing a bottom surface of the cavity for feeding the fluid into a bottom area of the cavity. An inner shell of the heat dissipating body includes a first portion and a second portion, each portion having at least two ribs transversally displaced in relation to each other. At least one rib of one of the first and the second portion is transversally displaced in relation to each rib of the other of the first and the second portion.

Abstract: An electrical heating apparatus for a motor vehicle includes a volume for receiving and conducting a liquid, a liquid inlet and a liquid outlet. The liquid can flow in through the liquid inlet into the volume and can flow out through the liquid outlet. At least one heating element is arranged in the volume. At least one deviating device is provided in such a way that the liquid flowing from the liquid inlet to the liquid outlet is deviated so that a flow path is increased.

Abstract: The invention relates to a burner (10), particularly for vehicle heaters, comprising a flexible panel (12) that separates an inner combustion region (14) from an outer region (16), a light-sensitive sensor for flame recognition being arranged in the outer region (16), and the flexible panel (12) comprising at least one light opening (20) that allows the passage of light from the inner combustion region (14) into the outer region (16). According to the invention, the light opening (20) is also provided so as to allow the passage of combustion air from the outer region (16) into the inner combustion region (14). The invention also relates to a vehicle heater.

Abstract: A porous fuel treatment element (5) for an evaporation burner is provided, said porous fuel treatment element (5) having at least one first tier (8) of a textile planar structure which is formed from a plurality of fibers. The fibers in the first tier (8) comprise at least two different fiber types (10, 11) which differ in terms of the material, of the cross-sectional profile, of the surface structure, and/or of the thickness.

Abstract: The invention relates to a porous fuel treatment element for an evaporation burner, comprising at least one layer (8) formed by fibers (10). Said fibers (10) comprise basalt fibers.

Abstract: The invention relates to a heat exchanger (10) having an internal conduct (32) for conducting a fluid, and having a heat dissipating body (12, 12?) for dissipating heat of the fluid, wherein the heat dissipating body (12, 12?) having a cavity (14, 14?) extending in a longitudinal direction (36), at least one end piece (34) of the internal conduct (32) extending inside of the cavity (14, 14?) the end piece (34) having an orifice (42) facing a bottom surface (44) of the cavity (14, 14?) for feeding the fluid into a bottom area of the cavity, wherein between an outer shell (48) of the internal conduct (32) and an inner shell (20, 20?) of the heat dissipating body (12, 12?) a streaming space for conducting the fluid away from the bottom (46) is provided, the streaming space extending in the longitudinal direction (36).
