<p>An evaporator is provided with a downstream heat exchange section (10) and an upstream heat exchange section (20) which are provided with heat exchange paths (31), upper tanks (11, 21), and lower tanks (12, 22) and are arranged so as to face each other in the air flow direction. The respective heat exchange paths (31) of the downstream heat exchange section (10) and the upstream heat exchange section (20) are partitioned by partition plates (51), which are provided to the upper tanks (11, 21) and the lower tanks (12, 22), into paths in which a refrigerant flows in the top-bottom direction. A refrigerant inlet opening (7) and a refrigerant outlet opening (8) are provided at ends of the upper tanks (11, 21). Among the partition plates (51) provided so as to guide a refrigerant, which comes from the refrigerant inlet opening (7), to the refrigerant outlet opening (8) such that the flow of the refrigerant repeats downward flows and upward flows, a partition plate (51) for separating from each other a first path (10a) and a second path (10b) of the downstream heat exchange section (10) is provided with a refrigerant pass through hole (52) for guiding a portion of the refrigerant, which comes from the refrigerant inlet opening (7), to a third path (10c) of the downstream heat exchange section (10).</p> |
