Patent ID: 7021371

Claim:
A two-block heat exchanger including plate shaped refrigerant distribution parts comprising two overlapped plates that have been drawing processed and between which two separate refrigerant paths are formed, said distribution parts being alternatively layered with a refrigerant fin, at least one opening that opens into said refrigerant paths being respectively formed in each two plates of said refrigerant distribution parts, wherein: said opening is provided at both respective ends of said refrigerant paths forming thereby, for each of said refrigerant paths of each of said distribution part, a refrigerant entrance and a refrigerant exit, a continuous refrigerant circulation space being formed by abutting said refrigerant entrances at the entrance side of respective refrigerant paths and a continuous refrigerant circulation space being formed by abutting said refrigerant exits at the exit side of respective refrigerant paths, and one end of each of said refrigerant circulating spaces is closed off and the other end is opened, the open end of said refrigerant circulation space at the exit side of one of said refrigerant paths being corrected to the open end of said refrigerant circulation space at the entrance side of said other refrigerant path, further comprising, in at least one of said refrigerant circulation spaces at the entrance side of said refrigerant paths, a baffle plate formed at the end of at least one of said two plates around said openings in order to prevent that all the refrigerant present in the refrigerant entrance positioned upstream said baffle plate flows into the refrigerant entrance positioned downstream said baffle plate, wherein each of said openings of said baffle plate is larger than the corresponding opening of an adjacent baffle plate in the direction of flow of the refrigerant and each of said openings of said baffle plate is disposed so as not to completely overlap the corresponding opening of the adjacent baffle plate.
