Claim 4:
5. The heat exchanger of claim 4, further comprising:
two upper inlet and outlet pipes connected to the two first headers connected to the respective upper ends of the first heat transfer pipe group and the second heat transfer pipe group; and
two lower inlet and outlet pipes connected to the two third headers connected to the respective lower ends of the third heat transfer pipe group and the fourth heat transfer pipe group,
wherein the two upper inlet and outlet pipes and the two lower inlet and outlet pipes are connected to the same side as the first communicating pipe and the second communicating pipe in the second orientation so that in the first heat exchange unit, the two first headers connected to the upper ends and the two second headers connected to the lower ends are opposite in refrigerant flow direction to each other and, in the second heat exchange unit, the two second headers connected to the upper ends and the two third headers connected to the lower ends are opposite in refrigerant flow direction to each other.
