FIELD: heating.
SUBSTANCE: invention relates to the device with heat exchangers for thermoelectric generator. The device with a heat exchanger (1) which has at least one housing (2) with an inlet (3) and an outlet (4) for the fluid (5) and an inner tube (6) with the axial direction (7), the first end (8) and the opposing second end (9) and also the first peripheral surface (10) with openings (11), in addition, with a plurality of tubes (12) of the heat exchanger, which are arranged parallel to the axial direction (7) outside on the first peripheral surface (10). The housing (2) surrounds the tubes (12) of the heat exchanger and the inner tube (6), and the inlet (3) is hydrodynamically connected to the first end (8). The guide elements (13) between the tubes (12) of the heat exchanger are arranged so that the fluid (5) which through the first end (8) enters the inner tube (6), in the radial direction (14), flowing from the inner tube (6), flows around the tubes (12) of the heat exchanger and then directed to the discharge channel (15) located in the radial direction (14) between the tubes (12) of the heat exchanger and the housing (2), and is rotated there in a direction (16) of the flow in the axial direction (7). The discharge channel (15) is hydrodynamically connected to the outlet (4), and the outer tube (19) is provided, which extends around the inner tube (6) and tubes (12) of the heat exchanger and has a second peripheral surface (20) with openings (11). The guide elements (13) are connected to the inner tube (6) and/or the outer tube (19).
EFFECT: technical result of the invention is to provide more efficient cooling of exhaust gases.
