Claims

[Scope of utility model registration request]

A main body is formed by a tube in which a flow passage for heat exchange fluid is formed and a plurality of plate-shaped fins arranged in parallel on the outer surface of this tube, and the heat exchange fluid is guided along each fin and connected to the tube. In a heat exchanger that performs heat exchange between blown air and a heat exchange fluid flowing inside the tubular body, a notch is provided at a rear position of the tubular body on the downstream side of the air blown onto the tubular body in each of the fins; A heat exchanger characterized in that heat exchange convex portions each having a shape corresponding to the notch are provided at a front position of the tube body on the upstream side of the air blown onto the tube body.
