<p>PROBLEM TO BE SOLVED: To provide a three-fluid heat exchanger capable of suppressing heat exchange between a first heated fluid and a second heated fluid while enhancing heat exchange between a heating fluid and the first heated fluid, and heat exchange between the heating fluid and the second heated fluid.SOLUTION: A three-fluid heat exchanger includes: a first heat transfer pipe in which a first heated fluid flows; a second heat transfer pipe in which a second heated fluid flows; a third heat transfer pipe in which a heating fluid flows; and a holding member of substantially-rectangular parallelepiped shape. The first heat transfer pipe is disposed near a first face of the holding member. The second heat transfer pipe is disposed near a second face of the holding member. The third heat transfer pipe is disposed in the middle of the first face and the second face. The first face of the holding member is provided with first recessed grooves at both sides of the first heat transfer pipe along the first heat transfer pipe. The second face of the holding member is provided with second recessed grooves at both sides of the second heat transfer pipe along the second heat transfer pipe.</p> |
