PROBLEM TO BE SOLVED: To provide a heat exchanger whose heat exchanging performance is prevented from deteriorating while requiring a relatively smaller installation space. SOLUTION: The heat exchanger 1 comprises a plurality of heat exchanging parts 2 arranged in parallel, and a pair of connectors 3 which are spaced from each other and to which all heat exchanging parts 2 are connected at both ends. Each heat exchanging part 2 has a first fluid passage 6 and a second fluid passage 7 formed around the first fluid passage 6. Each connector 3 has a first flow path 13 for communicating the first fluid passage 6 of the heat exchanging part 2 with the outside and a second flow path 16 independent from the first flow path 13 for communicating the second fluid passage 7 of the heat exchanging part 2 with the outside. The heat exchanging part 2 consists of an outer tube 4 and an inner tube 5 arranged in the outer tube 4 at a space. The first fluid passage 6 exists in the inner tube 4, and the second fluid passage 7 exists in a gap between the outer tube 4 and the inner tube 5. COPYRIGHT: (C)2006,JPO&NCIPI
