Abstract
A heat exchanger includes: heat transfer tubes aligned in an up-down direction; a liquid header connected to ends of the heat transfer tubes; and connection tubes aligned in the up-down direction and connected to the liquid header. The heat transfer tubes include: a first heat transfer tube disposed at a lowermost position; and a second heat transfer tube disposed above and adjacent to the first heat transfer tube. The connection tubes include: a first connection tube disposed at a lowermost position; and a second connection tube disposed above the first connection tube. The liquid header includes: a first flow path connected to the first connection tube and the first heat transfer tube; and a second flow path connected to the second connection tube and the second heat transfer tube.
