Claim:
1. A heat exchanger comprising: a plurality of refrigerant tubes disposed spaced apart from each other; a header joined to both ends of each of the refrigerant tubes; at least one baffle to block a longitudinal flow of a refrigerant flowing in the header and divide the refrigerant tubes into a plurality of mutually adjacent groups, each of the groups causing the refrigerant to flow in one direction; and a booster installed to vary a cross-sectional area of the header to uniformly distribute the refrigerant to refrigerant tubes in the same group among the refrigerant tubes, the booster comprising a blocking plate movable within the header to vary a cross-sectional area of the header dependent on an internal pressure of the header, whereby when the internal pressure of the header increases the blocking plate is configured to move within the header to reduce the cross-sectional of the header.
