Claims

[Claims for Utility Model Registration] (1) A pipe through which a fluid flows, a plurality of divided heat radiation fins each having a flat surface that contacts the pipe, and the plurality of heat radiation fins brought close to the pipe. and fixing means for pressing the contact flat part against the outer periphery of the pipe. (2) The heat exchanger according to claim 1, wherein the contact plane portion is a divided cylindrical surface that comes into close contact with the outer periphery of the pipe. (3) The heat exchanger according to claim 1 or 2, wherein the contact plane is a spacing between heat dissipating fins adjacent to each other in the longitudinal direction of the pipe. (4) The fixing means is in the form of a frame that surrounds the outside of the plurality of divided heat dissipation fins, according to any one of claims 1 to 3 of the utility model registration claim. heat exchanger. (5) The above-mentioned utility model registration claim 1, 2 or 4 is characterized in that the contact plane is formed by a plurality of radiation fins fixed in parallel to each other on the outer periphery of the divided cylindrical body. Heat exchanger as described.
