Abstract:
A heat exchanger includes: a plurality of flat pipes each having flat surfaces directed upward and downward, wherein the flat pipes are arranged in an up-down direction and extend in a fin stacking direction intersecting an air flow direction; and a plurality of heat transfer fins stacked in the fin stacking direction and each including: a plurality of cutouts into which the flat pipes are inserted, respectively, wherein the cutouts extend from a leeward side toward a windward side in the air flow direction; a plurality of fin main parts each formed between the cutouts adjacent to each other in the up-down direction; a fin windward part continuously extending from the fin main parts in the air flow direction toward the windward side of the cutouts; and a fin collar part extending from a peripheral portion of each of the cutouts toward one side in the fin stacking direction.

Claim (Index 6):
A heat exchanger comprising:\n a plurality of flat pipes each having flat surfaces directed upward and downward, wherein the flat pipes are arranged in an up-down direction and extend in a fin stacking direction intersecting an air flow direction; and a plurality of heat transfer fins stacked in the fin stacking direction and each comprising:\n a plurality of cutouts into which the flat pipes are inserted, respectively, wherein the cutouts extend from a leeward side toward a windward side in the air flow direction; \n a plurality of fin main parts each framed between the cutouts adjacent to each other in the up-down direction; \n a fin windward part continuously extending from the fin main parts in the air flow direction toward the windward side of the cutouts; and \n a fin collar part extending from a peripheral portion of each of the cutouts toward one side in the fin stacking direction, \n wherein for each of the fin collar parts:\n a gap extending in the air flow direction is formed between a flat upper surface of the flat pipe and a fin collar upper portion, \n the fin collar upper portion is a portion of the fin collar part along the flat upper surface, and \n the fin collar upper portion comprises a window portion through which the gap communicates with a space that is between the fin main parts adjacent to each other in the fin stacking direction and that is on an upper side of the fin collar upper portion, \n wherein the fin collar upper portion comprises a flare portion having a tip that curves upward into an R-shape, and wherein the gap is formed between the flare portion and the flat upper surface, and wherein the window portion is formed in the flare portion.
