Abstract:
A heat exchanger includes a first heat exchanging portion including first and second flat tubes stacked in parallel with each other and spaced from each other to allow fluid to pass between the first and second flat tubes, and a second heat exchanging portion including third and fourth flat tubes stacked in parallel with each other, spaced from each other to allow fluid to pass between the third and fourth flat tubes, and oriented crosswise to a direction in which the first and second flat tubes are oriented. The second heat exchanging portion is arranged downstream of the first heat exchanging portion with respect to flow of the fluid.

Claim (Index 1):
A heat exchanger comprising:\n a plurality of heat exchanging bodies including a first heat exchanging body and a second heat exchanging body, the first and second heat exchanging bodies each including a first heat exchanging portion including first and second flat tubes stacked in parallel with each other to allow fluid to pass between the first and second flat tubes; and a second heat exchanging portion including third and fourth flat tubes stacked in parallel with each other to allow fluid to pass between the third and fourth flat tubes, the second heat exchanging body being arranged downstream of the first heat exchanging body in a direction of the flow of the fluid, the first heat exchanging body and the second heat exchanging body being configured such that the third flat tube of the second heat exchanging portion is oriented crosswise to the first flat tube of the first heat exchanging portion in a cross-section perpendicular to a longitudinal direction of the third flat tube, the fourth flat tube of the second heat exchanging portion is oriented crosswise to the second flat tube of the first heat exchanging portion in a cross-section perpendicular to a longitudinal direction of the fourth flat tube, wherein lengths of the first and second flat tubes of the second heat exchanging body in a transverse direction are larger than lengths of the first and second flat tubes of the first heat exchanging body in the transverse direction, wherein angles formed between the first and second flat tubes of the second heat exchanging body and the direction of the flow of the fluid are larger than angles formed between the first and second flat tubes of the first heat exchanging body and the direction of the flow of the fluid, wherein lengths of the third and fourth flat tubes of the second heat exchanging body in the transverse direction are larger than lengths of the third and fourth flat tubes of the first heat exchanging body in the transverse direction, and wherein angles formed between the third and fourth flat tubes of the second heat exchanging body and the direction of the flow of the fluid are larger than angles formed between the third and fourth flat tubes of the first heat exchanging body and the direction of the flow of the fluid.
