Abstract:
Provided is a heat exchanger, including: a first heat exchange unit, which includes a first flat tube; a second heat exchange unit, which is arranged so as to be opposed to the first heat exchange unit, and includes a second flat tube; and a tank, which connects the first heat exchange unit and the second heat exchange unit to each other. The tank has an upper wall and a lower wall defining an upper end and lower end of a tank space formed in the tank, respectively. One end of the first flat tube and one end of the second flat tube are connected to the tank space. When a height from the lower wall to the upper wall is defined as X, and a height from the lower wall to the one end of the first flat tube is defined as Y 1,  a relation between X and Y 1  satisfies Y 1 <(1/2)X.

Claim (Index 4):
A heat exchanger, comprising:\n a first heat exchange unit including a first flat tube configured to allow refrigerant to flow therethrough, and configured to exchange heat between the refrigerant and air; a second heat exchange unit arranged so as to be opposed to the first heat exchange unit, including a second flat tube configured to allow the refrigerant to flow therethrough, and configured to exchange heat between the refrigerant and the air; and a tank connecting the first heat exchange unit and the second heat exchange unit to each other the tank having an upper wall and a lower wall defining an upper end and a lower end of a tank space formed in the tank, respectively, one end of each of a plurality of the first flat tubes arrayed in parallel to each other in an up-and-down direction and one end of each of a plurality of the second flat tubes arrayed in parallel to each other in the up-and-down direction being connected to the tank space, a number of the first flat tubes connected to the tank space and a number of the second flat tubes connected to the tank space being equal, the one end of the each of the plurality of the first flat tubes and the one end of the each of the plurality of the second flat tubes being connected at the same height position in the tank space, and when a height from the lower wall to one end of a first flat tube at a lowermost stage among the plurality of the first flat tubes connected to the tank space is defined as Y 2 , and an array pitch of the plurality of the first flat tubes in the up-and-down direction is defined as Z, a relation between Y 2  and Z satisfying Y 2 <(1/2)Z.
