PROBLEM TO BE SOLVED: To provide a heat exchange body in a first flow channel and to provide a heat exchanger for exchanging heat energy between the heat exchange body in the first flow channel and an external heat exchange body.SOLUTION: A first flow guide pipe body (101) is composed of a thermal conductor and includes at least one first flow channel (102) in its inside, both ends of the at least one first flow channel (102) are connected to two first joining rooms (103), and first fluid gateways (104) are respectively formed in the two first joining rooms (103). A second flow guide pipe body (201) is composed of a thermal conductor, formed so as to cover the outside of the first flow channel (102) of the first flow guide pipe body (101) and includes at least one second flow channel (202) having an annular cross section formed so as to cover the first flow channel (102), both ends of the at least one second flow channel (202) are connected to two second joining rooms (203), and second fluid gateways (204) are respectively formed in the two second joining rooms (203). |
