<p>A heat exchanger (1) for recovering energy from a fluid, and an energy recovery device and an energy recovery system comprising the heat exchanger (1). The heat exchanger (1) comprises: a first fluid collector (11) provided with an opening (111) for introducing a first fluid, a cavity (113) and an outlet (112); a first fluid flow guide (12) provided with a first fluid duct (114) communicating with the opening (111) and the outlet (112) of the first fluid collector (11); a second fluid flow guide (13) provided with a second fluid inlet (131), a flow division chamber (132), a plurality of heat exchange tubes (133), a flow collection chamber (134) and a second fluid outlet (135), a plurality of first fluid annular spaces (141) being formed between the outer wall of the heat exchange tubes (133) and the inner wall of the first fluid duct (114), wherein a second fluid is introduced through the second fluid inlet (131) and flows through the plurality of heat exchange tubes (133) and performs heat exchange with the first fluid flowing through the first fluid annular spaces (141). The heat exchanger (1), the energy recovery device and the energy recovery system can effectively recover energy from fluid, and installation thereof is simple and the use thereof convenient.</p> |
