Heat exchanger

摘要

The invention has as an object providing a two-block heat exchanger that can improve the heat exchange capacity by distributing the refrigerant evenly in the refrigerant path. The invention is a two-block heat exchanger, and the refrigerant distribution part provides two separate refrigerant paths R 1 and R 2 through which the refrigerant flows and an opening provided at both of the respective ends of these refrigerant paths R 1 and R 1. Among the two refrigerant paths R 1 and R 2, the open end of the space Sout 1 (refrigerant circulation space) on the exit side formed by the one opening of the one refrigerant path R 1 is connected to the open end of the space Sin 2 (refrigerant circulation space) on the entrance side formed by one opening of the other refrigerant path R 2. After the refrigerant flows into the refrigerant path R 1 of each refrigerant distribution part, and refrigerant flows through the refrigerant path R 2 of each of the refrigerant distribution parts.
