Abstract
A laminated-type heat exchanger has plural flat tubes in which refrigerant flows and plural corrugated fins each of which is disposed between adjacent two flat tubes. In the heat exchanger, plural protrusion portions protrude from an outer wall surface of each flat tube toward the corrugated fins, so that recess portions through which air flows are provided at least between adjacent protrusion portions. The protrusion portions are provided such that air meanderingly flows through the recess portions from an upstream end side to a downstream end side of each tube in a flow direction of air.
