[0004] Description of the Related Art
[0005] In conventional total heat exchangers, a total heat
exchanging core is disposed in the central portion of the total
heat exchanger, and fans are disposed on two sides of the total
heat exchanging core to impel the air flow. The fans are disposed
in an upright position. The total heat exchanging core exchanges
the heat and the moisture with the air flow, and recycles
energy.
[0006] In conventional total heat exchangers, the dimensions of the
fans are restricted by the dimensions of the total heat exchanging
core. The small fans produce noise, and cannot generate sufficient
rates of flow. However, if the dimensions of the fans are
increased, the dimensions of the total heat exchanging core and the
whole total heat exchanger are increased. Additionally, the
capability of the total heat exchanging core cannot be sufficiently
exerted.

[0010] In one embodiment, the first inlet chamber and the second
inlet chamber are arranged in a first direction, and the first
direction is perpendicular to the plane.
[0011] In one embodiment, the housing further comprises a third
side wall and a fourth side wall. The first side wall faces the
second side wall. The third side wall faces the fourth side wall.
The first inlet is formed on the third side wall. The second inlet
is formed on the fourth side wall.
[0012] In one embodiment, a first flow enters the total heat
exchanger through the first inlet, passes through the first inlet
chamber, the total heat exchanging core and the first fan, and
leaves the total heat exchanger through the first outlet. A second
flow enters the total heat exchanger through the second inlet,

[0016] In one embodiment, the first inlet chamber has an inlet
chamber length L, a distance d1 is formed between the first guiding
structure and the first inlet, and 0.ltoreq.d1.ltoreq.L/2.
[0017] In one embodiment, the first inlet chamber has a greatest
inlet chamber width W, the first guiding structure has a structural
width d2, and W/3.ltoreq.d2.ltoreq.W.
[0018] In one embodiment, the first inlet chamber has a greatest

first fan 21, the second fan 22 and the total heat exchanging core
30 are arranged on a plane P, and the first rotation axis 211 and
the second rotation axis 221 are perpendicular to the plane P.
[0032] In one embodiment, the housing 10 further comprises a second
side wall 102. The first receiving space 11 and the second
receiving space 12 are adjacent to the second side wall 102. The
first receiving space 11 and the second receiving space 12 are
located between the second side wall 102 and the third receiving
space 13.
[0033] In the embodiment of the invention, the total heat
exchanging core 30 is adjacent to the first side wall 101. The heat
exchanging area of the total heat exchanging core 30 is increased,
and the air flow can smoothly enter the total heat exchanging core
30. The first fan 21 and the second fan 22 lay on the plane P (in
other words, the first rotation axis 211 and the second rotation
axis 221 are perpendicular to the plane P). The first fan 21 and
the second fan 22 are adjacent to the second wall 102. Therefore,
the dimensions of the first fan 21 and the second fan 22 can be
increased to improve flow rate and to reduce noise.
[0034] In one embodiment, a first inlet chamber 41 and a second
inlet chamber 42 are formed inside the housing 10. A first inlet
43, a second inlet 44, a first outlet 45 and a second outlet 46 are
formed on the housing 10. The first inlet chamber 41 and the second
inlet chamber 42 correspond to the total heat exchanging core 30.
The first inlet 43 is connected to the first inlet chamber 41. The
second inlet 44 is connected to the second inlet chamber 42. The
first outlet 45 corresponds to the first fan 21, and the second
outlet 46 corresponds to the second fan 22.
[0035] In one embodiment, the first inlet chamber 41 and the second
inlet chamber 42 are arranged in a first direction Z. The first
direction Z is perpendicular to the plane P.
[0036] In one embodiment, the housing 10 further comprises a third
side wall 103 and a fourth side wall 104. The first side wall 101
faces the second side wall 102. The third side wall 103 faces the
fourth side wall 104. The first inlet 42 is formed on the third
side wall 103. The second inlet 44 is formed on the fourth side
wall 104.
[0037] FIG. 2A shows the air flow inside the total heat exchanger
1. FIG. 2B is a cross sectional view along 2B-2B' direction of FIG.
2A. FIG. 2C is a cross sectional view along 2C-2C' direction of
FIG. 2A. With reference to FIGS. 2A, 2B and 2C, in one embodiment,
a first flow A1 enters the total heat exchanger 1 through the first
inlet 43, passes through the first inlet chamber 41, the total heat
exchanging core 30 and the first fan 21, and leaves the total heat
exchanger 1 through the first outlet 45. A second flow A2 enters
the total heat exchanger 1 through the second inlet 44, passes
through the second inlet chamber 42, the total heat exchanging core
30 and the second fan 22, and leaves the total heat exchanger 1
through the second outlet 46.
[0038] With reference to FIGS. 1, 2A, 2B and 2C, in one embodiment,
the total heat exchanger 1 further comprises a first guiding
structure 51 and a second guiding structure 52. The first guiding
structure 51 is disposed in the first inlet chamber 41 to push the
first flow A1 toward the total heat exchanging core 30. The second
guiding structure 52 is disposed in the second inlet chamber 42 to
push the second flow A2 toward the total heat exchanging core 30.
In this embodiment, the first guiding structure 51 and the second
guiding structure 52 are formed on the first side wall 101.
[0039] In one embodiment of the invention, the first guiding
structure 51 and the second guiding structure 52 push the first
flow A1 and the second flow A2 toward the total heat exchanging
core 30 to improve the heat exchanging efficiency of the total heat
exchanging core 30.
[0040] However, in several embodiments, the first guiding structure
51 and the second guiding structure 52 may decrease the flow rate
of the total heat exchanger. Therefore, with reference to FIGS. 3A,
3B and 3C, in one embodiment, each of the first guiding structure
51 and the second guiding structure 52 has through openings 53. For
example, in FIG. 3A, the first guiding structure 51 has
longitudinal openings 53 (fences shaped) which extend in the Z
direction. In FIG. 3B, the longitudinal openings 53 (fences shaped)
extend in X direction. In FIG. 3C, the first guiding structure 51
has circular openings 53. The through openings on the first guiding
structure 51 and the second guiding structure 52 are adapted for
modifying the flow rate of the total heat exchanger.
[0041] FIG. 4A shows the position and the dimensions of the first
guiding structure 51. In one embodiment, the first inlet chamber 41
has an inlet chamber length L, a distance d1 is formed between the
first guiding structure 51 and the first inlet 43, and
0.ltoreq.d1.ltoreq.L/2. With reference to FIG. 4B, the first inlet
chamber 41 has a greatest inlet chamber width W, the first guiding
structure 51 has a structural width d2, and W/3.ltoreq.d2.ltoreq.W.
The first inlet chamber 41 has a greatest inlet chamber height H,
the first guiding structure 51 has a structural height d3, and
H/3.ltoreq.d3.ltoreq.H. Experiments confirms that the heat
exchanging efficiency of the total heat exchanger according to the
above design is improved. However, the disclosure is not meant to
restrict the invention. The position and dimensions of the second
guiding structure 52 can be the same as those of the first guiding
structure 51.
[0042] Use of ordinal terms such as "first", "second", "third",
etc., in the claims to modify a claim element does not by itself
connote any priority, precedence, or order of one claim element
over another or the temporal order in which acts of a method are
performed, but are used merely as labels to distinguish one claim
element having a certain name from another element having the same
name (but for use of the ordinal term).
[0043] While the invention has been described by way of example and
in terms of the preferred embodiments, it is to be understood that
the invention is not limited to the disclosed embodiments. On the
contrary, it is intended to cover various modifications and similar
arrangements (as would be apparent to those skilled in the art).
Therefore, the scope of the appended claims should be accorded the
broadest interpretation so as to encompass all such modifications
and similar arrangements.
