  • the bend angles of the end portions from the intermediate portion of each of the branch heat exchangers can be set to any angles in consideration of the dimensions of the product main body, the relationship between the length for a bender used for bending each of the branch heat exchangers to grip on and the bending lengths of the end portions of each of the branch heat exchangers, convenience of a pipe connection operation on the branch heat exchangers, and the like. Manufacturing disadvantages to the branch heat exchangers are averted in this manner.
  • each first end portion is preferably bent at a bend angle not more than forty-five degrees.

  • the first end portion of each of the branch heat exchangers is preferably connected to flow dividing pipes from a flow divider.
  • the flow dividing pipes are preferably arranged in a substantially triangular region formed by an outermost straight line and two leader lines.

  • the air conditioner can be made compact.
  • the heat exchanger is preferably configured to allow a plurality of refrigerant outlet pipes from the two branch heat exchangers to be connected to one header.
  • the mechanical fan is preferably located closer to the second end portion in the longitudinal direction of the product main body.
  • the space between the mechanical fan and the first end portions is made larger than the space between the mechanical fan and the second end portions.
  • the larger space can be utilized effectively as a space for purposes such as connection and wiring between an electric component box and electric components. Electric components, such as a drain pump, are often connected to parts near the first end portions in particular.
  • the larger space between the mechanical fan and the first end portions is advantageous for the connection of such electric components.
  • the mechanical fan is preferably one of two mechanical fans, which are spaced in the longitudinal direction of the product main body, and a midpoint between the two mechanical fans is closer to the second end portion.
  • the two mechanical fans are positioned closer to the second end portions in the product main body.
