to embodiments of the present invention, wherein an end cap for an end of a manifold
of the heat exchanger has been omitted, hence that end of the heat exchange tube which

exchange part 21 by bending twice, and each heat exchange tube 20 comprises two heat
exchange parts.
[0028] Referring to figs. 1 to 16, according to some embodiments of the present invention,
each heat exchange tube 20 also has a plurality of third heat exchange parts disposed

the second heat exchange part 22 are arranged in a first direction D1, and extend
in a second direction D2 which is substantially perpendicular to the first direction
D1, and said same side of the heat exchanger 100 is the same side in the second direction
D2, in a plane defined by the first direction D1 and the second direction D2.
[0030] As shown in figs. 5 to 12, the second end 25 deviates from a center line (i.e. an
axis, axial center line or longitudinal center line of a tube section forming the
heat exchange part) of the second heat exchange part 22 by curving, and the first
end 24 and the second end 25 deviate in opposite directions.
[0031] In the embodiment shown in figs. 5 to 8, the first end 24 and the second end 25 deviate
from the center line of the first heat exchange part 21 and the center line of the
second heat exchange part 22 respectively by bending twice, and each heat exchange
tube 20 comprises two heat exchange parts; by forming a plurality of connecting parts
23, each heat exchange tube 20 may comprise four or more heat exchange parts.
[0032] As shown in figs. 2 to 4, the first heat exchange part 21 and the second heat exchange
part 22 are arranged in the first direction D1 (i.e. an axial direction of the first
manifold 11 and the second manifold 12), and extend in the second direction D2 which
is substantially perpendicular to the first direction D1; and the first end 24 deviates
from the center line of the first heat exchange part 21 in a third direction D3 which
is substantially perpendicular to the first direction D1 and the second direction
D2. The first manifold 11 and the second manifold 12 are disposed in the third direction
D3. For example, the first end 24 deviates from the center line of the first heat
exchange part 21 by curving substantially in a plane defined by the second direction
D2 and the third direction D3. According to some embodiments of the present invention,
the first end 24 and the first heat exchange part 21 of each heat exchange tube 20
may lie substantially in the plane defined by the second direction D2 and the third
direction D3.
[0033] As shown in figs. 6 to 8 and 10 to 12, the first heat exchange part 21 and the second
heat exchange part 22 are arranged in the first direction D1 (i.e. the axial direction
of the first manifold 11 and the second manifold 12), and extend in the second direction
D2 which is substantially perpendicular to the first direction D1; the first end 24
deviates from the center line of the first heat exchange part 21 in the third direction
D3 which is substantially perpendicular to the first direction D1 and the second direction
D2, and the second end 25 deviates from the center line of the second heat exchange
part 22 in the third direction D3 which is substantially perpendicular to the first

plane defined by the second direction D2 and the third direction D3, and the second
end 25 deviates from the center line of the second heat exchange part 22 by curving
substantially in the plane defined by the second direction D2 and the third direction

first heat exchange part 21 of each heat exchange tube 20 lie substantially in the
plane defined by the second direction D2 and the third direction D3, and the second
end 25 and the second heat exchange part 22 of each heat exchange tube 20 lie substantially
in the plane defined by the second direction D2 and the third direction D3.
[0034] In the embodiment shown in figs. 1 to 4, a direction of extension of a part 241,
connected to the first manifold 11, of the first end 24 of each heat exchange tube
20 is substantially the same as the direction of extension of the first heat exchange
part 21. For example, the part 241, connected to the first manifold 11, of the first
end 24 of each heat exchange tube 20 extends substantially in the second direction
D2.
[0035] In the embodiment shown in figs. 5 to 8, the direction of extension of the part 241,
connected to the first manifold 11, of the first end 24 of each heat exchange tube
20 is substantially the same as the direction of extension of the first heat exchange
part 21, and a direction of extension of a part 251, connected to the second manifold
12, of the second end 25 of each heat exchange tube 20 is substantially the same as
the direction of extension of the second heat exchange part 22. For example, the part
241, connected to the first manifold 11, of the first end 24 of each heat exchange
tube 20 extends substantially in the second direction D2, and the part 251, connected
to the second manifold 12, of the second end 25 of each heat exchange tube 20 extends
substantially in the second direction D2.
[0036] Referring to figs. 9 to 12, the first end 24 (e.g. a center line of the first end
24 (i.e. an axis, axial center line or longitudinal center line of a tube section
forming the end)) of each heat exchange tube 20 is inclined relative to the first
heat exchange part 21 (e.g. the center line of the first heat exchange part 21 (i.e.
the axis, axial center line or longitudinal center line of the tube section forming
the first heat exchange part 21)). In the embodiment shown in figs. 9 to 12, the first
end 24 and the second end 25 deviate from the center line of the first heat exchange
part 21 and the center line of the second heat exchange part 22 respectively by bending
once, and each heat exchange tube 20 comprises two heat exchange parts; by forming
a plurality of connecting parts 23, each heat exchange tube 20 may comprise four or
more heat exchange parts.
[0037] In the embodiment shown in figs. 9 to 12, the first end 24 of each heat exchange
tube 20 is inclined relative to the first heat exchange part 21, and the second end
25 (e.g. a center line of the second end 25 (i.e. an axis, axial center line or longitudinal
center line of a tube section forming the end)) of each heat exchange tube 20 is inclined
relative to the second heat exchange part 22 (e.g. the center line of the second heat
exchange part 22 (i.e. the axis, axial center line or longitudinal center line of
the tube section forming the second heat exchange part 22)).
[0038] A heat insulating space 40 or heat insulating element may be disposed between the
first manifold 11 and the second manifold 12, and may prevent heat exchange between
the two manifolds and the formation of a heat bridge, which would affect the heat
exchange effect of the heat exchanger. The first manifold 11 and the second manifold
12 may be two separate manifolds, but could also be a first manifold 11 and a second
manifold 12 formed from one tube by means of a longitudinal partition plate. The longitudinal
partition plate may be two partition plates; the two partition plates may be integral
with pipe walls of the pipes, but could also be separate.
[0039] As shown in figs. 14 to 16, the first manifold 11 and the second manifold 12 are
manifolds with D-shaped cross sections, and substantially flat surfaces of the two
manifolds with the D-shaped cross sections face each other. A gap is provided between
the first manifold 11 and the second manifold 12. The heat insulating element may
be disposed in the gap.
[0040] The heat exchanger according to an embodiment of the present invention may be used
in the fields of heating, ventilating and air conditioning, motor vehicles, refrigeration
and transport, and may be a micro-channel heat exchanger or a parallel-flow heat exchanger,
etc. The heat exchanger according to an embodiment of the present invention can reduce
costs, increase the wind field uniformity and output wind temperature uniformity of
a micro-channel heat pump evaporator, and increase the utilization rate of the heat
exchange area.
[0041] Moreover, in the heat exchanger according to the present invention, a partition plate
may be disposed in the manifold, so as to form different circuits. In addition, in
the heat exchanger according to the present invention, the circuit length may be adjusted
as required (with the heat exchange tube being bent a number of times). When the heat
exchanger is used in an evaporator, the difference between the condensate water produced
by the top portion and condensate water of the bottom-half portion is not large, the
wind field of the heat exchanger is more uniform, and the output wind temperatures
of various parts of the heat exchanger are more uniform.
[0042] Furthermore, in the heat exchanger according to the present invention, the manifolds
are arranged at a single side, so connecting pipelines and manifolds are saved, and
costs are lower. In addition, a single row of flat tubes may be employed, so that
wind resistance is low.
