same thickness as the second supporting part T25. As shown in FIG.
7, the first supporting part T15 may be connected to a central part
in a length direction of the first heat exchange tube T1, and be of
a shorter length than the first heat exchange tube T1 so that the
connection of the ends of the first heat exchange tube T1 to the
headers M1 is not affected; similarly, the second supporting part
T25 may be connected to a central part in a length direction of the
second heat exchange tube T2, and be of a shorter length than the
second heat exchange tube T2 so that the connection of the ends of
the second heat exchange tube T2 to the headers M2 is not affected.
The use of the first supporting part T15 and the second supporting
part T25 enables the first parts 31 and the second parts 32 of the
fins 3 to be supported, and facilitates the conduction of heat from
the first heat exchange tube T1 and the second heat exchange tube
T2 to the fins 3.
[0058] Referring to FIGS. 10 to 18, in some embodiments of the
present invention, each of the at least multiple fins 3 in the set
of fins 3 has a first part 31 and a second part 32; the at least
multiple first heat exchange tubes T1 in the set of first heat
exchange tubes T1 have first heat exchange tube first parts T11 in
contact with the first parts 31 and first heat exchange tube second
parts T12 in contact with the second parts 32, and the at least
multiple second heat exchange tubes T2 in the set of second heat
exchange tubes T2 have second heat exchange tube first parts T21 in
contact with the first parts 31 and second heat exchange tube
second parts T22 in contact with the second parts 32. According to
an example of the present invention, when viewed in the arrangement
direction A, the at least multiple first heat exchange tubes T1 in
the set of first heat exchange tubes T1 and the at least multiple
second heat exchange tubes T2 in the set of second heat exchange
tubes T2 cross over each other. According to an example of the
present invention, the first part 31 and the second part 32 of each
of the at least multiple fins 3 in the set of fins 3, when viewed
in the arrangement direction A, are disposed side by side in the
width direction of the fin 3 (the left-right direction in FIGS. 1
and 2), and furthermore may be disposed substantially symmetrically
relative to a center line extending in the length direction of the
fin 3 (the up-down direction in FIGS. 10 and 11).
[0059] Referring to FIGS. 10 to 14, in some embodiments of the
present invention, the at least multiple first heat exchange tubes
T1 or at least partial regions of the at least multiple first heat
exchange tubes T1 in the set of first heat exchange tubes T1 are
disposed obliquely relative to the length direction of the at least
multiple fins 3 in the set of fins 3, and the at least multiple
second heat exchange tubes T2 or at least partial regions of the at
least multiple second heat exchange tubes T2 in the set of second
heat exchange tubes T2 are disposed obliquely relative to the
length direction of the at least multiple fins 3 in the set of fins
3. In other words, in a plane defined by a thickness direction of
the heat exchanger 100 and the length direction of the fins 3, the
at least multiple first heat exchange tubes T1 or at least partial
regions of the at least multiple first heat exchange tubes T1 in
the set of first heat exchange tubes T1 are disposed obliquely
relative to the length direction of the at least multiple fins 3 in
the set of fins 3, and the at least multiple second heat exchange
tubes T2 or at least partial regions of the at least multiple
second heat exchange tubes T2 in the set of second heat exchange
tubes T2 are disposed obliquely relative to the length direction of
the at least multiple fins 3 in the set of fins 3. According to an
example of the present invention, the at least multiple first heat
exchange tubes T1 in the set of first heat exchange tubes T1 and
the at least multiple second heat exchange tubes T2 in the set of
second heat exchange tubes T2 may be straight tubes. In this
embodiment, the first heat exchange tubes T1 and the second heat
exchange tubes T2 share the fins 3; the width of each fin 3 is the
sum of the width of the first heat exchange tube T1, the width of
the second heat exchange tube T2 and a gap between the first part
31 and the second part 32. According to an example of the present
invention, the first part 31 and the second part 32 of each of the
at least multiple fins 3 in the set of fins 3, when viewed in the
arrangement direction A, are disposed side by side in a width
direction of the fin 3 (the left-right direction in FIGS. 1 and 2),
and furthermore may be disposed substantially symmetrically
relative to a center line extending in a length direction of the
fin 3 (the up-down direction in FIGS. 10 and 11). In this
embodiment, the outlets of the two circuits may be located on a
windward side, whereby the two circuits are arranged such that a
flow direction of a heat exchange medium in the heat exchanger is
opposite to a flow direction of air, thereby facilitating heat
exchange.
[0060] Referring to FIGS. 15 to 18, in some embodiments of the
present invention, the at least multiple first heat exchange tubes
T1 in the set of first heat exchange tubes T1 also have first heat
exchange tube third parts T13, which are located between the first
heat exchange tube first parts T11 and the first heat exchange tube
second parts T12 and connect the first heat exchange tube first
parts T11 to the first heat exchange tube second parts T12, and the
at least multiple second heat exchange tubes T2 in the set of
second heat exchange tubes T2 also have second heat exchange tube
third parts T23, which are located between the second heat exchange
tube first parts T21 and the second heat exchange tube second parts
T22 and connect the second heat exchange tube first parts T21 to
the second heat exchange tube second parts T22. According to an
example of the present invention, the first heat exchange tube
first parts T11 and the first heat exchange tube second parts T12
extend substantially in the length direction of the fins 3, and the
second heat exchange tube first parts T21 and the second heat
exchange tube second parts T22 extend substantially in the length
direction of the fins 3. In this embodiment, the first heat
exchange tubes T1 and the second heat exchange tubes T2 share the
fins 3; the width of each fin 3 is the sum of the width of the
first heat exchange tube T1, the width of the second heat exchange
tube T2 and a gap between the first part 31 and the second part 32.
According to an example of the present invention, the first part 31
and the second part 32 of each of the at least multiple fins 3 in
the set of fins 3, when viewed in the arrangement direction A, are
disposed side by side in the width direction of the fin 3 (the
left-right direction in FIGS. 1 and 2), and furthermore may be
disposed substantially symmetrically relative to a center line
extending in the length direction of the fin 3 (the up-down
direction in FIGS. 15 and 16). In this embodiment, the first heat
exchange tubes T1 and the second heat exchange tubes T2 are
straight tubes, and central parts in the length direction thereof
have bent parts. Thus, the heat exchanger according to this
embodiment is easier to manufacture.
[0061] Referring to FIGS. 19 to 22, in some embodiments of the
present invention, ends of the at least multiple second heat
exchange tubes T2 in the set of second heat exchange tubes T2
project from the set of fins 3 in the thickness direction of the
heat exchanger 100. The at least multiple first heat exchange tubes
T1 in the set of first heat exchange tubes T1, middle parts between
two ends of the at least multiple second heat exchange tubes T2 in
the set of second heat exchange tubes T2, and the at least multiple
fins 3 in the set of fins 3 are arranged in a row in the
arrangement direction A. In this embodiment, the first heat
exchange tubes T1 and the second heat exchange tubes T2 share the
fins 3; the width of the fins 3 is approximately equal to the width
of the first heat exchange tubes T1 and the width of the second
heat exchange tubes T2. In this embodiment, the first heat exchange
tubes T1 are straight tubes. Except for the ends of the second heat
exchange tubes T2, the second heat exchange tubes T2 are straight
tubes, with the ends of the second heat exchange tubes T2 being
bent and protruding outside a core body of the heat exchanger, so
that the second heat exchange tubes T2 can be connected to the
corresponding headers M2. The ends of the second heat exchange
tubes T2 are not in contact with the fins 3.
[0062] According to embodiments of the present invention, as shown
in FIGS. 1 to 26, the set of fins 3 is arranged in a row. According
to an example of the present invention, the set of fins 3 is
arranged in a row, the set of first heat exchange tubes T1 is
arranged in a row, and the set of second heat exchange tubes T2 is
arranged in a row.
[0063] As shown in FIGS. 23 to 26, any suitable structure may be
employed for the headers M1 and M2. For instance, a structure in
which the headers are separate as shown in FIG. 23; a structure in
which the headers are connected to each other as shown in FIGS. 24
and 26; and a structure in which the headers are formed using a
single tube by means of a partition plate as shown in FIG. 25.
[0064] According to an embodiment of the present invention, since
the first heat exchange tubes T1 and the second heat exchange tubes
T2 share the fins 3, if one circuit of a dual-circuit
air-conditioning system is closed, then a heat exchange region of
the fins used for that circuit can be used for the other circuit,
thereby increasing the heat exchange efficiency of the heat
exchanger.
[0065] In addition, the above embodiments according to the present
invention may be combined to form new embodiments.
[0066] While the present disclosure has been illustrated and
described with respect to a particular embodiment thereof, it
should be appreciated by those of ordinary skill in the art that
various modifications to this disclosure may be made without
departing from the spirit and scope of the present disclosure.
