PURPOSE:To improve the heat exchanger efficiency of the titled heat exchanger by a method wherein a heat transfer fine layer is provided adjacent a heat pipe layer so that the flow direction of a low temperature fluid and that of a high temperature fluid flows at right angle to the axis of each of heat pipes forming the heat pipe layer. CONSTITUTION:The flat heat pipes 11 are arranged parallel to one another so as to form the heat pipe layer 12 and the heat transfer fin layer 15 having low temperature fluid passages 16a and low temperature fluid passages 16b separated from the formers by a partition plate 14 is arranged adjacent the heat pipe layer 12. Further, the heat transfer fins 13a and 13b forming the heat transfer fin layer 15 are arranged in such a manner that the flow directions of the flow and high temperature fluids become normal to the axis of each of the heat pipes 11. Then the heat pipes 11 are incorporated into the heat exchanger so as to make use of the advantages of both the heat pipes and the fins. As a consequence, it is possible to obtain the orthogonal cross-flow type heat exchanger which has a small pressure loss and which is small-sized. |
