It addition, the height H of described dividing plate 250 is formed as, be equivalent to described secondary series pipe arrangement portion 243 Below the height H2 of upper end.If the height H-shaped of described dividing plate 250 becomes described height H2 Above, the upper end of the most described dividing plate 250 is positioned closely adjacent at the position in described 3rd row pipe arrangement portion 245, Thus, it is possible to create following problem, i.e. during second refrigerant flows, occur the 3rd row to join Pipe portion 245 rocks, thus because described 3rd row pipe arrangement portion 245 and described dividing plate 250 come in contact Produce noise.
Further, at the height H of described dividing plate 250 with described situation identical for height H2 be, described every The upper end of plate 250 is formed at the situation of the position tangent with described secondary series pipe arrangement portion 243.At this moment, Occur being difficult to described dividing plate 250 or the problem of support slot 253.
Therefore, the height H-shaped of the dividing plate 250 of the present embodiment becomes less than described height H2.For Zong It, the height H of described dividing plate 250 is formed as, bigger than described height H1 and than described height H2 Little.For convenience of description, described height H1 is referred to as " the first height ", is referred to as by described height H2 " the second height ".
It addition, described groove connecting portion 254 can be configured such that separate with described 3rd row pipe arrangement portion 245 away from From for, and value corresponding to distance d1 that separated between adjacent inner tube 240 is so much.In detail and Speech, when the pipe arrangement center from described 3rd row pipe arrangement portion 245, with the radius r set, definition for During the tangent imaginary concentric circular P1 of the pipe arrangement in described secondary series pipe arrangement portion 243, described groove connecting portion 254 It is configurable on and described imaginary position tangent for concentric circular P1.
