    Abstract: The invention relates to a heat exchanger (10) with an inner guide (32) for guiding a fluid and with a heat discharging element (12, 12') for discharging heat of the fluid. The heat discharging element (12, 12') has a cavity (14, 14') which extends in a longitudinal direction (36) and within which at least one end piece (34) of the inner guide (32) extends, said end piece (34) having an opening (42) which faces a base surface (44) of the cavity (14, 14') in order to introduce the fluid into a base region (46) of the cavity (14, 14'). A flow chamber for guiding the fluid away from the base region (46) is formed between an outer casing surface (48) of the inner guide (32) and an inner casing surface (20, 20') of the heat discharging element (12, 12'), said flow chamber extending in the longitudinal direction (36). The inner casing surface (20, 20') of the heat discharging element (12, 12') has a first portion (20), which has at least two ribs (22) that are transversely offset relative to each other, and a second portion (20'), which adjoins the first portion (20) and which comprises at least two ribs (22') that are transversely offset relative to each other. At least one rib (22') of the second portion (20') is transversely offset relative to each rib (22) of the first portion (20), or at least one rib (22) of the first portion (20) is transversely offset relative to each rib (22') of the second portion (20'). The invention further relates to a method for producing such a heat exchanger.

    Abstract: The present invention relates to a silencer device for a fluid line which comprises a resonator arrangement which comprises a first resonator tube comprising a first resonator chamber designed for a lambda/4 damping of at least one sound wavelength, wherein the first resonator tube comprises a first longitudinal direction, two end walls facing each other in the first longitudinal direction and a first side wall extending between the end walls, and wherein the first resonator chamber is formed between the first side wall and the end walls of the first resonator tube. The resonator arrangement further comprises a second resonator tube comprising a second resonator chamber designed for a lambda/4 damping of at least one sound wavelength, wherein the second resonator tube comprises a second longitudinal direction, two end walls facing each other in the second longitudinal direction and a second side wall extending between the end walls, and wherein the second resonator chamber is formed between the second side wall and the end walls of the second resonator tube. The invention further relates to a heating device comprising such a silencer device.
