To provide a header system required for manufacturing a small and highly efficient heat exchanger of simple structure.
The heat exchanger has an elongated pipe structure comprising three rows of flat multi-opening tubular material 30, 40 and 50 wherein the first and third rows of tubular material 30 and 50 hold the second row of tubular material 40 between. The second row of tubular material 40 terminates at the opposite end parts 42 and 44 receiving refrigerant joints 46 and 48, respectively. Each of the first and third rows of tubular material 30 and 50 include a running path touching the tubular material 40 in heat exchanging relation. Opposite end parts 32 and 34 of the tubular material 30 extend around the refrigerant joints 46 and 48 and receive refrigerant joints 36 and 38. The tubular material 50 includes parts 52 and 54 extending around the refrigerant joints 46 and 48 and terminating at the opposite end parts 56 and 58 which are fluid communicating with the joints 36 and 38.
