徴とする請求項１記載の熱交換器。[Claims for Utility Model Registration] 1. A plurality of heat exchanger tubes are provided in parallel, and a large number of corrugated fins with louvers are provided on the outer periphery of the heat exchanger tubes, and a first fluid flows inside the heat exchanger tubes, and a fluid flows outside the heat exchanger tubes. A second fluid having a flow velocity distribution of a fast part and a slow part flows in the first heat transfer tube.
In a heat exchanger installed such that the second fluid flows at right angles to the flow direction of the second fluid, the dimensions of the louver are set such that the flow velocity of the second fluid is uniform on the downstream side of the heat exchanger. A heat exchanger characterized by being modified to correspond to the distribution. 2. The heat exchanger according to claim 1, wherein the angle of the louver is set higher in a portion where the flow velocity is high and lower in a portion where the flow velocity is slow. 3. The heat exchanger according to claim 1, wherein the number of louvers is increased in a portion where the flow velocity is high and decreased in a portion where the flow velocity is slow.
