Abstract: PURPOSE:To contrive the reduction of a pressure loss of fluid, flowing out-side of a pipe, as well as the improvement of heat exchanging efficiency by a method wherein plate type water conducting means, connecting between pipes, are provided on the side surface of the downstream side of a laminated flat pipe for conducting the other fluid, flowing inside of the pipe. CONSTITUTION:In a heat exchanger 1, pipes 2 for fluid, flowing inside of the pipe, are arranged with an equal interval while linear heat transfer bodies 3 are arranged in parallel between said pipes 2 for the fluid, flowing inside of the tube, and are secured to the flat parts of the pipes 2 by brazing. Further, water conducting means 5, connecting between the pipes and provided with an integrated plate type, are secured to the side surfaces of the downstream side of the air flow of the pipes 2. Soldering, brazing, welding by adhesive agent and the like are employed for the method of securing, however, hydrophilic material is preferable for the material of each securing method.
