1. A heat exchanger comprising:
a first header unit including a body, a cover and an intermediate barrier wall to divide the first header unit into a first header and a second header; a second header unit including a body, a cover and an intermediate barrier wall to divide the second header unit into a third header and a fourth header; a first heat exchanging unit arranged between the first header of the first header unit and the third header of the second header unit; and a second heat exchanging unit arranged between the second header of the first header unit and the fourth header of the second header unit, wherein each of the first header of the first header unit and the third and fourth headers of the second header unit is partitioned into a plurality of sections by at least one partition plate, to define a plurality of refrigerant circuits, through which a plurality of refrigerant paths flows, and the second header of the first header unit has a single section, to allow refrigerant to flow in the second header of the first header unit in the form of a unified flow, wherein the first header of the first header unit communicates with a plurality of refrigerant introduction pipes, and the second header of the first header unit communicates with a single refrigerant discharge pipe, wherein the refrigerant discharge pipe is arranged at a longitudinal end of the first header unit, and wherein a portion of the intermediate barrier wall is partially removed from a region immediately adjacent the refrigerant discharge pipe whereby the first and second headers of the first header unit, communicate with each other in the region to reduce flow resistance of the refrigerant. |
