Mesh fin type heat exchanger and method of making the same
 The heat exchanger includes a plurality of heat transfer tubes 1, 1 . . . arranged in parallel, and a multiplicity of mesh-form fins 2, 2 . . . arranged parallel to axes of the tubes and joined to the heat transfer tubes 1, 1 . . . . Each of the heat transfer tubes 1 consists of a pair of tube component members 4, 4 of a half cylindrical configuration having, at their respective circumferential ends, joining flanges 4a, 4b extending along the axis of the tube. The opposed joining flanges 4a, 4b of the tube component members 4, 4 are joined together by being pressed against the fins 2, 2 from outer side thereof. This provides for improvement in operating efficiency in the process of assembling heat transfer tubes and mesh-form fins together.
