<p>PROBLEM TO BE SOLVED: To provide a heat exchanger satisfying requirements of pressure loss, current velocity, manufacturing cost, and adhesion of fur. SOLUTION: A coil-like pipe 2 is arranged around cylinders 1a, 1b except for the outermost pipe 1c among a plurality of cylinders 1a-1c concentrically and spacers are placed between the cylinders 1a, 1b and the inner pipe 2a of the coil-like pipe 2 and between the cylinders 1b, 1c and the outer pipe 2b. Fluid is fed to gaps 11a-11d formed by the spacer 10 and heat is exchanged between that fluid and the fluid flowing through the pipe 2.</p> |
