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). The inner shell (20, 20′) of the heat dissipating body (12, 12′) comprises a first portion (20) having at least two ribs (22) transversally displaced in relation to each other; and adjacent to the first portion (20) a second portion (20′) having at least two ribs (22′) transversally displaced in relation to each other. At least one rib (22′) of the second portion (20′) is transversally displaced in relation to each rib (22) of the first portion (20) or at least one rib (22) of the first portion (20) is transversally displaced in relation to each rib (22′) of the second portion (20′). The invention further relates to a method of manufacturing of such a heat exchanger.

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:
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.
