PURPOSE:To provide a heat exchanger having a high heat exchange efficiency and easy to manufacture and inexpensive in cost by combining plates with fins by constituting the heat exchanger of a fluid separating parts and a counterflow part. CONSTITUTION:A fluid A enters a hollow part 14 via lead-in fins 4 in each of heat exchange elements 12, and is led out through leadout fins 5 and flows rectilinearly. A fluid B enters a heat exchange element 13 from a hollow part 17 and passes a central fin 6. Then, the fluid B is led out via a hollow part 16. As a result, fluids A and B effect heat exchange through plates 3. In this case, at the central fin 6 and a flowpath contiguous thereto is formed a counterflow shape. Further, at the lead-in fin 4, lead-out fin 5 and a flowpath contiguous thereto is formed a shape close to a directly intersecting shape. By skilfully combining the hollow part with the fin part, a heat exchanger high in the heat exchange efficiency is obtained. |
