Title:
HEAT EXCHANGER
Document Type and Number:
Japanese Patent JP2017133790
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To easily bend a heat exchanger into an L-shape without blocking a refrigerant flow passage in a flat tube by solving a problem that, when bending the heat exchanger into the L-shape, it is necessary to bend the heat exchanger so that a flat face of the flat tube is upwardly oriented because the flat tube is fixed to fins since the flat tube is a heat transfer tube whose cross section shape is oblong or rectangular having round corners, and the flat tube is difficult to be bent, thus causing the block of the refrigerant flow passage in the flat tube.SOLUTION: In this heat exchanger, a first flat tube group in which a first flat tube part is aligned in a vertical direction is formed, a second flat tube group in which a second flat tube part is aligned in a vertical direction is formed, a bending part group in which a bending part is aligned in a vertical direction is formed, a fin group in which a plurality of fins are aligned is formed, the fin group has a first fin group and a second fin group, the first fin group intersects with the first flat tube group, and the second fin group intersects with the second flat tube group.SELECTED DRAWING: Figure 1
