Title: HEAT EXCHANGER FOR FLUID
Abstract:
The invention relates to a fluid-recirculation heat exchanger device (1), intended to transfer thermal energy from or to a circulating fluid from the environment outside the device, comprising at least one main pipe (2) in which a flow of main fluid (P) is capable of flowing, comprising an inlet channel (3) comprising a Venturi effect device made up of a convergent upstream portion (4) followed by a divergent downstream portion (5), a central channel (C), an outlet channel (10) for at least one portion of the flow of main fluid (P), at least one bypass pipe (6A, 6B) separate from the main pipe (2), in which a portion of the flow of main fluid is capable of flowing, the inlet (7A, 7B) of which is placed in the downstream portion of the main pipe (2), and the outlet (8A, 8B) of which is placed at the Venturi effect device. The invention is characterized in that one dimension of the cross-section of the main pipe (2) is very substantially greater than the other dimension.
