First straight section 21 is tangent at the first end with the segmental arc 23 and forms cross-shaped portion therebetween
Position, second straight section 22 is tangent at second end with the segmental arc 23 and forms intersection area therebetween.
This is the preferred of the three stage structure (including one section of segmental arc and two sections of coupled respectively straight sections) of the present invention
And specific structure type, the first straight section is connected with segmental arc, and connecting part is just at first end and in the first end
It is tangent with segmental arc to locate the first straight section, can effectively prevent between straight section and segmental arc formed flex point and so that air-flow flows through
When produce resistance, so as to reduce resistance caused by airflow passes evaporator, reduce energy loss, improve heat exchange efficiency；Equally
, the second straight section is connected with segmental arc, and connecting part the first straight section and arc just at the second end and at second end
Shape section is tangent, can effectively prevent between straight section and segmental arc formed flex point and cause resistance is produced when air-flow flows through so that
Reduce resistance caused by airflow passes evaporator, reduce energy loss, improve heat exchange efficiency.
Preferably, first straight section, which includes long side and short side, the second straight section, also includes long side and short side, the angle φ
The acute angle being crossed to form for the long side extended line of first straight section and the long side extended line of second straight section.This is this
