Description

Ventilation assembly of airflow exchange device

Technical Field

The invention relates to a ventilation component of an airflow exchange device, in particular to a ventilation component of an airflow exchange device which can enable an external space and an internal space to achieve a circulating ventilation function.

Background

Referring to fig. 1, a conventional airflow exchanging device is disclosed, which can be installed on, for example, an outer wall of a building or a housing of an electronic product. The air exchange device is provided with a ventilation assembly 9, and the ventilation assembly 9 comprises an air guide tube body 91, a partition 92 and two fans 93. The air guiding tube 91 has a first end 911 and a second end 912 formed at two ends thereof, and the first end 911 and the second end 912 can be disposed in an outdoor space and an indoor space, respectively. The partition 92 and the two fans 93 are disposed inside the air guiding tube 91, the partition 92 can partition the inside of the air guiding tube 91 into two air guiding spaces, and the two fans 93 are disposed on two side surfaces of the partition 92 respectively. Therefore, the air guiding tube 91 provided with the partition 92 and the two fans 93 is used for providing an airflow exchange function in the airflow exchange device, so that the air in the outdoor space and the air in the indoor space can be mutually circulated.

The partition 92 needs to abut against the inner peripheral wall of the air guiding tube 91, so that the interior of the air guiding tube 91 can be divided into two air guiding spaces. However, since there is no positioning structure between the partition 92 and the air guide tube 91, when the partition 92 is inserted into the air guide tube 91, the partition 92 is easily rotated in the air guide tube 91, which makes the assembly of the partition 92 difficult.

Moreover, the two side surfaces of the partition 92 need to be provided with a combination portion corresponding to the two fans 93 for combining and disposing the two fans 93, so that the structure of the partition 92 is complicated and the mold opening is not easy to manufacture.

In practical use, the air guiding tube 91 of the ventilation assembly 9 is inserted through a through hole formed in a partition (e.g., a wall surface of a building, a ceiling, or a housing of an electronic product) to mount the air exchange device to the partition. However, the thickness of the partition is different, so that the air guiding tube 91 has different lengths for being mounted on partitions with different thicknesses. Therefore, the manufacturer must provide the partitions 92 with different lengths corresponding to the air guide pipe bodies 91 with different lengths to ensure that the partitions 92 can divide the interior of the air guide pipe body 91 into two air guide spaces. However, designing and opening the mold to manufacture the partitions 92 with different specifications will result in a significant increase in the manufacturing and stock costs of the ventilation assembly 9.

In view of the above, it is desirable to provide a ventilation assembly of an airflow exchanging device, which is further improved to solve the problems of the conventional airflow exchanging device, such as "difficult assembly", "complicated structure", and high manufacturing and material preparation costs ", etc.

Detailed Description

In order to make the aforementioned and other objects, features and advantages of the present invention comprehensible, preferred embodiments accompanied with figures are described in detail below.

Referring to fig. 2 and 3, a ventilation assembly of an airflow exchanging device according to a first embodiment of the present invention includes an air guiding tube 1, a partition 2 and a fan 3, wherein the partition 2 and the fan 3 are respectively disposed inside the air guiding tube 1.

The air guiding pipe 1 can be a hollow pipe with various shapes, in this embodiment, the air guiding pipe 1 is a hollow circular pipe, however, the air guiding pipe 1 can also be a hollow square pipe or other various hollow tubular columns, and the invention is not limited thereto. The two ends of the air guiding pipe body 1 in the long axis direction X are respectively a first opening 11 and a second opening 12, and a track 13 is arranged inside the air guiding pipe body 1, and the track 13 can be arranged on the inner peripheral wall of the air guiding pipe body 1, so that the track 13 can be integrated with the air guiding pipe body 1. The rail 13 is disposed between the first opening 11 and the second opening 12, and the rail 13 extends along the long axis direction X. In this embodiment, the air guiding tube 1 can extend from the first opening 11 to the second opening 12.

The partition 2 comprises at least one partition 21, and the partition 21 may be a plate made of metal, plastic or other materials. In this embodiment, the number of the at least one partition 21 is single, one side of the partition 21 is provided with an assembling portion 211, and the assembling portion 211 also extends along the long axis direction X. Thus, the assembling portion 211 is slidably coupled to the rail 13 of the air guide pipe body 1, so that the partition 2 is formed inside the air guide pipe body 1.

The fan 3 has a base 31 and a fan wheel 32. One side of the base 31 is provided with a combining portion 311, and the combining portion 311 also extends along the long axis direction X. Thereby, the combining portion 311 is slidably combined with the rail 13 of the air guide pipe body 1, so that the fan 3 is formed and arranged inside the air guide pipe body 1. The base 31 and the partition 2 can abut against each other, and specifically, the base 31 can abut against one end edge of the partition 2 facing the second opening 12 of the air guiding pipe body 1; alternatively, the base 31 may abut against the other end edge of the spacer 2 facing the first opening 11 of the air guide duct body 1.

In the actual assembly of the ventilation assembly of the airflow exchanging device according to the first embodiment of the present invention, the partition 2 and the fan 3 can be respectively coupled to the rail 13 of the air guiding tube body 1, and can slide along the rail 13 to place the partition 2 and the fan 3 inside the air guiding tube body 1. For example, the assembling personnel can combine the fan 3 with the rail 13 through the first opening 11 of the air guiding tube 1; pushing the fan 3 into the first opening 11 along the rail 13; then the separator 2 is combined with the track 13 through the first opening 11, so that the separator 2 is abutted against the base 31 of the fan 3; finally, the partition 2 is pushed into the first opening 11 along the rail 13, so that the partition 2 and the fan 3 are formed inside the air guiding tube 1. Similarly, the assembling personnel can combine the partition 2 and the fan 3 with the rail 13 through the second opening 12 of the air guiding tube 1 or respectively through the first opening 11 and the second opening 12, and slide along the rail 13 to place the partition 2 and the fan 3 into the air guiding tube 1.

Referring to fig. 4, when the partition 2 and the fan 3 are disposed inside the air guiding tube 1, the partition 2 and the base 31 of the fan 3 can abut against each other, so that the partition 2 and the base 31 can separate the inside of the air guiding tube 1 into a first air guiding space 1a and a second air guiding space 1 b. In this embodiment, the fan wheel 32 of the fan 3 can be disposed in the first guiding space 1a for guiding the airflow in the first guiding space 1 a; however, the fan wheel 32 can also be disposed in the second guiding space 1b for guiding the airflow in the second guiding space 1 b. Specifically, the first opening 11 of the air guiding tube 1 is provided with a first air inlet 111 and a first air outlet 112, and the second opening 12 of the air guiding tube 1 is provided with a second air inlet 121 and a second air outlet 122 for guiding air flow in and out. The first air guiding space 1a is communicated with the first air inlet 111 and the second air inlet 121, and the second air guiding space 1b is communicated with the first air outlet 112 and the second air outlet 122.

With the above structure, when the ventilation assembly of the airflow exchanging device of the first embodiment of the present invention is actually used, the air guiding tube body 1 can be installed and fixed on a partition D (e.g., a wall surface of a building, a ceiling, or a housing of an electronic product, etc.), one side of the partition D is an external space R1, and the opposite side of the partition D is an internal space R2. Therefore, the airflow exchanging device using the ventilation assembly of the first embodiment can guide the airflow guided into the external space R1 through the first air inlet 111 to the first guiding space 1a of the air guiding tube body 1, and guide the airflow guided into the first guiding space 1a through the second air inlet 121 to the internal space R2; moreover, the airflow in the inner space R2 can be further guided into the second guiding space 1b of the guiding tube 1 through the second air outlet 122, and then guided out to the outer space R1 from the first air outlet 112, so as to provide a good circulating ventilation function.

Since the fan wheel 32 of the fan 3 can be disposed in the first guiding space 1a in the embodiment, the fan 3 can guide the airflow in the first guiding space 1a to improve the efficiency of guiding the airflow of the external space R1 to the internal space R2. In some embodiments of the present invention, the fan wheel 32 may be disposed in the second guiding space 1b, so that the fan 3 can guide the airflow in the second guiding space 1b to improve the efficiency of guiding the airflow of the inner space R2 to the outer space R1.

Therefore, in the assembly process of the ventilation assembly of the airflow exchanging device according to the first embodiment of the present invention, since the inner peripheral wall of the air guiding tube body 1 is provided with the rail 13, the partition 2 and the fan 3 can be slidably coupled to the rail 13, so that an assembler can slide the partition 2 or the fan 3 along the rail 13 to place the partition 2 or the fan 3 inside the air guiding tube body 1, and the partition 2 or the fan 3 will be positioned by the rail 13, and therefore will not rotate in the air guiding tube body 1 any more. Compared with the prior art that there is no positioning structure between the partition 92 and the air guiding tube 91 of the ventilation assembly 9 of the airflow exchanging device, the partition 92 is easy to rotate in the air guiding tube 91, so that the assembly of the partition 92 is difficult.

Moreover, compared with the fan 93 of the ventilation assembly 9 of the conventional airflow exchanging device which is required to be arranged on the surface of the partition 92, since the fan 3 of the ventilation assembly of the airflow exchanging device of the first embodiment of the present invention can be directly combined with the rail 13 through the combining portion 311 of the base 31, the partition 2 does not need to be provided with a combining portion for combining the fan 3, and the structure of the partition 92 can be effectively simplified.

It should be noted that, the inner peripheral wall of the air guiding pipe body 1 may be provided with another rail 13 ', the another rail 13 ' is also disposed between the first opening 11 and the second opening 12 and extends along the long axis direction X, and the two rails 13, 13 ' may be disposed opposite to each other in the radial direction of the air guiding pipe body 1, which is not limited thereto. Accordingly, the partition plate 21 of the partition 2 may be provided with another assembling portion 211 ', the two assembling portions 211, 211' are respectively disposed at both sides of the partition plate 21, and the two assembling portions 211, 211 'can be respectively slidably coupled to the two rails 13, 13' of the air guide pipe body 1. Similarly, the base 31 of the fan 3 may be provided with another combination portion 311 ', the two combination portions 311, 311' are respectively disposed at two sides of the base 31, and the two combination portions 311, 311 'can be respectively slidably combined with the two tracks 13, 13' of the air guiding tube body 1. Therefore, the partition 21 of the partition 2 can be combined with the two rails 13, 13 'through the two assembling portions 211, 211', and the base 31 of the fan 3 can also be combined with the two rails 13, 13 'through the two combining portions 311, 311', so as to further improve the combining stability and the air tightness between the partition 2 and the fan 3 and the air guiding pipe body 1.

As shown in fig. 4, since the rail 13 of the air guiding duct body 1, the assembling portion 211 of the partition 2, and the connecting portion 311 of the base 31 of the fan 3 all extend along the long axis direction X, the rail 13, the assembling portion 211, and the connecting portion 311 respectively have a rail length W1, an assembling portion length W2, and a connecting portion length W3 in the long axis direction X, and the rail length W1 may be greater than or equal to the sum of the assembling portion length W2 and the connecting portion length W3(W1 ≧ W2+ W3), so as to ensure that the partition 2 and the fan 3 can be simultaneously connected to the rail 13.

In this embodiment, the air guiding tube body 1 may further include a sleeve 14, and the sleeve 14 is disposed at one end of the air guiding tube body 1 having the first opening 11. In contrast, the airflow exchanging device using the ventilation assembly of the first embodiment may be provided with a base 4, and the base 4 is disposed at one end of the air guiding pipe body 1 having the second opening 12. Therefore, the partition 2 and the fan 3 of the ventilation assembly of the first embodiment can be limited between the sleeve 14 and the base 4, so that the partition 2 and the fan 3 can be fixed in the air guiding pipe body 1 without sliding along the rail 13. The track 13 of the air guiding pipe body 1 may be provided with a first assembling portion 131 on one side facing the second opening 12, the base 4 may be provided with a second assembling portion 41, and the second assembling portion 41 and the first assembling portion 131 can be assembled and combined with each other to fix the base 4 to the air guiding pipe body 1. In this embodiment, the first assembling portion 131 of the rail 13 can be a screw member (e.g., a screw hole or a bolt), and the second assembling portion 41 of the base 4 can be a through hole, so that a locking element S (e.g., a screw or a nut) can assemble and fix the base 4 to the air guiding pipe body 1.

On the other hand, referring to fig. 5 and fig. 6, another embodiment of the ventilation assembly of the airflow exchanging device according to the first embodiment of the present invention is different from the foregoing embodiment in that: the rail 13 may be provided separately from the inner circumferential wall of the air guide pipe body 1, so that the rail 13 and the air guide pipe body 1 can form a separate member. Specifically, one side of the rail 13 may also be provided with a first assembling portion 131, and the base 4 may be provided with a second assembling portion 41, wherein the second assembling portion 41 can be assembled with the first assembling portion 131 to fix the rail 13 to the base 4. The air guiding tube 1 can be abutted against the base 4, so that the rail 13 can be formed and arranged inside the air guiding tube 1, and the rail 13 is also arranged between the first opening 11 and the second opening 12 and extends along the long axis direction X.

As described above, in the present embodiment, the rail 13 is provided separately from the inner peripheral wall of the air guide duct body 1, but the rail 13 is also provided inside the air guide duct body 1 and extends along the longitudinal direction X, and therefore, in the actual assembly of the present embodiment, the partition 2 and the fan 3 can be respectively coupled to the rail 13 of the air guide duct body 1 and can be slid along the rail 13 to place the partition 2 and the fan 3 inside the air guide duct body 1.

Referring to fig. 7 and 8, a ventilation assembly of an airflow exchanging device according to a second embodiment of the present invention is shown, the ventilation assembly of the airflow exchanging device according to the second embodiment of the present invention can be installed on a thinner partition D, and the air guiding tube body 1 must have a shorter length in the long axis direction X to prevent the portion of the air guiding tube body 1 protruding out of the partition D from being too long. In the present embodiment, the length of the air guiding tube 1 is approximately equal to the length of the fan 3 in the major axis direction X, and the inner peripheral wall of the air guiding tube 1 is provided with the rail 13, so that the fan 3 can be slidably combined with the rail 13, and the partition 2 is not required to be provided; on the contrary, the base 31 of the fan 3 can be used to divide the inside of the air guiding tube 1 into a first guiding space 1a and a second guiding space 1b by only disposing the fan 3 inside the air guiding tube 1.

As shown in fig. 8, the track length W1 of the track 13 of the air guide duct body 1 is only required to be greater than or equal to the coupling portion length W3 of the coupling portion 311 of the base 31 of the fan 3(W1 ≧ W3), so that the fan 3 can be surely coupled to the track 13.

Similarly, in the present embodiment, the track 13 may be provided separately from the inner circumferential wall of the air guiding pipe body 1, but another track 13 ' may also be provided inside the air guiding pipe body 1, the other track 13 ' is also provided separately from the inner circumferential wall of the air guiding pipe body 1, and the two tracks 13 and 13 ' may be provided opposite to each other in the radial direction of the air guiding pipe body 1. Therefore, the base 31 of the fan 3 can also be combined with the two rails 13 and 13 'through the two combining portions 311 and 311', so as to further improve the combining stability and the air tightness between the fan 3 and the air guiding pipe body 1. In addition, in the embodiment, each of the coupling portions 311, 311 ' may be a through hole penetrating through the base 31 along the long axis direction X for passing through each of the rails 13, 13 ', so that the fan 3 can be slidably coupled to each of the rails 13, 13 '.

Although the partition 2 is not provided in the present embodiment, if the air guide pipe body 1 is long and the partition 2 needs to be provided separately, the partition 21 of the partition 2 may be coupled to the two rails 13 and 13 'through the two assembling portions 211 and 211'. Similarly, each of the assembling portions 211, 211 ' may be a through hole penetrating the partition 21 along the long axis direction X for passing through each of the rails 13, 13 ', so that the partition 2 can be slidably coupled to each of the rails 13, 13 '.

Referring to fig. 9, a ventilation assembly of an airflow exchanging device according to a third embodiment of the present invention is different from the second embodiment in that: another fan 3 is included, so that the ventilation component of the airflow exchanging device of the second embodiment includes two fans 3 to improve the airflow exchanging efficiency. The two fans 3 can be respectively combined with the rail 13 through the combining part 311 of the base 31. In this embodiment, the air guiding tube 1 has a longer length than the air guiding tube 1 of the second embodiment, which is approximately equal to twice the length of the fan 3 in the long axis direction X, so that the two fans 3 can be arranged inside the air guiding tube 1 in a staggered manner; in other words, when the two fans 3 are disposed inside the air guiding tube 1, the bases 31 of the two fans 3 can abut against each other, so that the bases 31 of the two fans 3 can divide the inside of the air guiding tube 1 into the first air guiding space 1a and the second air guiding space 1b, and the two fans 3 can be disposed on planes perpendicular to the long axis direction X at an angle of 180 ° apart, so that the fan wheels 32 of the two fans 3 are disposed in the first air guiding space 1a and the second air guiding space 1b, respectively. Therefore, the ventilation component of the airflow exchanging device of the third embodiment can be respectively provided with a fan 32 in the first guiding space 1a and the second guiding space 1b to guide the airflow in the first guiding space 1a and the second guiding space 1 b.

The coupling portion 311 of the base 31 of each fan 3 and the rail 13 of the air guiding duct body 1 respectively has a rail length W1 and a coupling portion length W3 in the long axis direction X, and the rail length W1 may be greater than or equal to the sum (W1 ≧ 2 × W3) of the coupling portion lengths W3 of the fans 3, so as to ensure that the two fans 3 can be coupled to the rail 13 at the same time.

However, referring to fig. 10 and fig. 11, a ventilation assembly of an airflow exchanging device according to a fourth embodiment of the present invention is different from the aforementioned third embodiment in that: the two fans 3 are overlapped with each other on a plane perpendicular to the long axis direction X to form an alignment arrangement inside the air guiding pipe body 1, so that the air guiding pipe body 1 is prevented from occupying a space in the long axis direction X, and the air guiding pipe body 1 can have a shorter length (approximately equal to the length of one of the fans 3 in the long axis direction X). The bases 31 of the two fans 3 can still separate the inside of the air guiding tube 1 into the first air guiding space 1a and the second air guiding space 1b, and the fan wheels 32 of the two fans 3 can be respectively formed in the first air guiding space 1a and the second air guiding space 1 b. As shown in fig. 11, the track length W1 of the track 13 of the air guide duct body 1 is only required to be greater than or equal to the coupling portion length W3 of the coupling portion 311 of one of the fans 3(W1 ≧ W3), so that the two fans 3 can be simultaneously coupled to the track 13. Furthermore, although in the present embodiment, the two fans 3 are independent components; in some embodiments of the present invention, the bases 31 of the two fans 3 may be integrally formed, so that the two fans 3 can share the same base 31, and when the base 31 is combined with the rail 13, the two fans 3 can be disposed inside the air guiding pipe body 1 and aligned.

Although the third and fourth embodiments are limited in that the air guiding tube body 1 has a short length, and the partition 2 is not provided, please refer to fig. 12 and 13, which show a ventilation assembly of an airflow exchanging device according to a fifth embodiment of the present invention, and the difference between the ventilation assembly and the third and fourth embodiments is that: the air flow exchange device further comprises a partition 2, so that the ventilation assembly of the air flow exchange device of the fifth embodiment is provided with the partition 2 and two fans 3 inside the air guiding tube body 1, thereby improving the air flow exchange efficiency and really separating the inside of the air guiding tube body 1 with a longer length into a first air guiding space 1a and a second air guiding space 1 b. More specifically, the partition 21 of the partition 2 may be coupled to the rail 13 via the assembling portion 211, and the two fans 3 may be coupled to the rail 13 via the coupling portions 311 of the bases 31. When the partition 2 and the two fans 3 are disposed inside the air guiding tube 1, the partition 2 and the bases 31 of the two fans 3 can abut against each other, so that the partition 2 and the bases 31 of the two fans 3 can partition the inside of the air guiding tube 1 into the first air guiding space 1a and the second air guiding space 1b, and the impeller 32 of the two fans 3 is disposed in the first air guiding space 1a and the second air guiding space 1b, respectively. Therefore, the ventilation component of the airflow exchanging device of the fifth embodiment can be respectively provided with the fan wheel 32 in the first guiding space 1a and the second guiding space 1b to respectively guide the airflow in the first guiding space 1a and the second guiding space 1 b.

Referring to fig. 13, the two fans 3 may be disposed on planes perpendicular to the long axis direction X with a 180 ° difference therebetween, so that the fan wheels 32 of the two fans 3 can be respectively formed in the first flow guiding space 1a and the second flow guiding space 1 b. In this embodiment, the bases 31 of the two fans 3 may abut against the two end edges of the partition 2, respectively. Specifically, one of the fans 3 may abut against one end edge of the partition 2 facing the second opening 12 of the air guide duct body 1, and the other fan 3 may abut against the other end edge of the partition 2 facing the first opening 11 of the air guide duct body 1. Accordingly, the rail 13 of the air guide duct body 1, the assembling portion 211 of the partition 2, and the coupling portion 311 of the base 31 of each fan 3 respectively have a rail length W1, an assembling portion length W2, and a coupling portion length W3 in the long axis direction X, and the rail length W1 may be greater than or equal to the sum of the assembling portion length W2 and the coupling portion length W3 of each fan 3(W1 ≧ W2+2 × W3), so as to ensure that the partition 2 and the two fans 3 can be simultaneously coupled to the rail 13. In other words, the air guiding tube 1 of the ventilation assembly of the airflow exchanging device of the fifth embodiment can have a longer length in the long axis direction X, so that the air guiding tube 1 can completely accommodate the partition 2 and the two fans 3, and accordingly, the ventilation assembly of the airflow exchanging device of the fifth embodiment is generally suitable for a partition D with a thicker thickness.

Referring to fig. 14, a ventilation assembly of an airflow exchanging device according to a sixth embodiment of the present invention is different from the fifth embodiment in that: the bases 31 of the two fans 3 can abut against one of the end edges of the partition 2, for example, in the present embodiment, the two fans 3 can abut against the end edge of the partition 2 facing the first opening 11 of the air guiding pipe body 1; alternatively, in another embodiment of the present invention, the two fans 3 may abut against the end edge of the partition 2 facing the second opening 12 of the air guide duct body 1. Therefore, the two fans 3 are overlapped with each other on the plane perpendicular to the long axis direction X to form an alignment arrangement inside the air guiding tube 1, and the space of the air guiding tube 1 in the long axis direction X is prevented from being occupied, so that the air guiding tube 1 can have a slightly shorter length than the air guiding tube 1 of the fifth embodiment, and can be applied to a spacer D having a thickness slightly smaller than that of the spacer D applied to the fifth embodiment. The partition 2 and the bases 31 of the two fans 3 can still separate the inside of the air guiding tube body 1 into the first air guiding space 1a and the second air guiding space 1b, and the fan wheels 32 of the two fans 3 can be respectively formed in the first air guiding space 1a and the second air guiding space 1b, and the track length W1 of the track 13 of the air guiding tube body 1 only needs to be greater than or equal to the sum of the assembling portion length W2 of the assembling portion 211 of the partition 2 and the combining portion length W3 of the combining portion 311 of one fan 3(W1 ≧ W2+ W3), so that the partition 2 and the two fans 3 can be simultaneously combined with the track 13. Similarly to the fourth embodiment, although in the present embodiment, the two fans 3 are each an independent member; in some embodiments of the present invention, the bases 31 of the two fans 3 may be integrally formed, so that the two fans 3 can share the same base 31, and when the base 31 is combined with the rail 13, the two fans 3 can be disposed inside the air guiding pipe body 1 and aligned.

Therefore, the ventilation assemblies of the airflow exchanging device according to the third, fourth, fifth and sixth embodiments of the present invention can dispose the two fans 3 in the air guiding tubes 1 with different lengths, so as to be suitable for the partitions D with different thicknesses. When the air guide tube body 1 has a shorter length corresponding to the thinner separator D, the separator 2 is not required to be disposed; on the contrary, when the air guiding pipe body 1 has a longer length corresponding to the thicker spacer D, only one additional spacer 2 is needed to separate the longer length of the air guiding pipe body 1 into a first flow guiding space 1a and a second flow guiding space 1 b. In addition, the two fans 3 can be arranged in the air guide pipe body 1 in a staggered manner or in an aligned manner, so that the two fans 3 (and the separators 2) can be further arranged in the air guide pipe bodies 1 with different lengths without providing the separators 2 with different specifications, the ventilation assembly of the airflow exchange device in each embodiment of the invention has a wider application range, and a manufacturer does not need to design and open a mold to manufacture the separators 2 with different specifications, and the ventilation assembly has the advantage of lower manufacturing and material preparation cost.

Referring to fig. 15 and 16, a ventilation assembly of an airflow exchanging device according to a seventh embodiment of the present invention is different from the aforementioned embodiments in that: the partition plate 21 of the partition member 2 is further provided with a plurality of fins 212, and the plurality of fins 212 may be integrally formed with the partition plate 21, or the plurality of fins 212 may be bonded to the surface of the partition plate 21 by welding or the like. The fins 212 are respectively disposed on the surfaces of the partition 21 facing the first flow guiding space 1a and the second flow guiding space 1b, such that a part of the fins 212 is located on one surface of the partition 2 facing the first flow guiding space 1a, and another part of the fins 212 is located on the other surface of the partition 2 facing the second flow guiding space 1 b. By providing the plurality of fins 212 on the partition 21, the partition 2 can provide a uniform temperature effect to reduce the temperature difference between the first flow guiding space 1a and the second flow guiding space 1 b.

It should be noted that, compared to the previous embodiments, the number of the at least one partition plate 21 included in the partition 2 is a single number, and as shown in fig. 17, the ventilation assembly of the airflow exchanging device according to the eighth embodiment of the present invention is shown, in this embodiment, the number of the at least one partition plate 21 may be several, and the partition plates 21 may abut against each other. The assembling portion 211 is disposed on one side of each partition 21, so that each partition 21 can be slidably coupled to the rail 13 of the air guiding pipe body 1 through the assembling portion 211. Therefore, an assembler can combine the partition boards 21 with the rail 13, so that the partition boards 21 are butted against each other end to jointly form the partition 2.

Therefore, the partition 2 of the ventilation assembly of the airflow exchanging device according to the embodiment of the present invention may be composed of one or more partitions 21, so that when the air guiding tube 1 has a longer length in the long axis direction X, the length of the partition 2 in the long axis direction X may be extended by increasing the number of the at least one partition 21, so as to ensure that the base 31 of the fan 3 can be abutted against the partition 2, and further, the partition 2 and the base 31 can reliably separate the inside of the air guiding tube 1 into the first flow guiding space 1a and the second flow guiding space 1 b. Relatively, when the air guiding pipe body 1 has a short length in the long axis direction X, the length of the partition 2 in the long axis direction X can be shortened by reducing the number of the at least one partition 21, so as to avoid occupying the space of the air guiding pipe body 1 in the long axis direction X, and the air guiding pipe body 1 can completely accommodate the partition 2 and the fan 3. In addition, when the number of the at least one partition 21 needs to be reduced to zero, that is, the partition 2 does not need to be disposed, as shown in the second, third and fourth embodiments, the fan 3 is only required to be disposed inside the air guiding tube 1, and the base 31 of the fan 3 can be used to separate the first air guiding space 1a and the second air guiding space 1b from the inside of the air guiding tube 1.

For example, as shown in fig. 17, when the ventilation component of the airflow exchanging device according to the eighth embodiment is to be installed on a partition D with a relatively thick thickness, the air guiding pipe body 1 has a relatively long length in the long axis direction X, so as to ensure that the air guiding pipe body 1 can pass through the partition D. Accordingly, the partition 2 may be composed of three partitions 21 to extend the length of the partition 2 in the long axis direction X. In contrast, referring to fig. 18, when the ventilation assembly of the airflow exchanging device of the eighth embodiment is to be installed on the thin partition D, the air guiding tube body 1 preferably has a shorter length in the long axis direction X, so as to avoid that the portion of the air guiding tube body 1 protruding out of the partition D is too long. Accordingly, the separator 2 may be composed of only two separators 21 to shorten the length of the separator 2 in the long axis direction X.

Therefore, compared with the prior art in which the ventilation assembly 9 of the airflow exchange device must provide the partition 92 with different lengths corresponding to the air guide tube 91 with different lengths, the partition 2 of the ventilation assembly of the airflow exchange device according to the embodiment of the present invention is composed of at least one partition 21, and the length of the partition 2 in the long axis direction X can be adjusted by only increasing or decreasing the number of the at least one partition 21, so that the partitions 2 with different specifications do not need to be designed and manufactured by opening a mold, and the manufacturing and stock costs of the ventilation assembly can be effectively reduced.

As shown in fig. 17, in the present embodiment, the number of the at least one partition 21 is three, the bases 31 of the two fans 3 can respectively abut against two end edges of the partition 2, the rail 13 of the air guiding duct body 1, the assembling portion 211 of each partition 21, and the connecting portion 311 of the base 31 of each fan 3 respectively have a rail length W1, an assembling portion length W2, and a connecting portion length W3 in the long axis direction X, and the rail length W1 can be greater than or equal to the sum (W1 ≧ 3 × W2+2 × W3) of the assembling portion length W2 of each partition 21 and the connecting portion length W3 of each fan 3, so as to ensure that the partition 2 and the two fans 3 can be simultaneously connected to the rail 13.

Although in the foregoing embodiments, the rail 13 of the air guiding pipe body 1 is a convex portion, and the assembling portion 211 of the partition plate 21 of the partition 2 and the coupling portion 311 of the base 31 of the fan 3 are each a concave portion, so that the assembling portion 211 and the concave portion of the coupling portion 311 are slidably coupled to the convex portion of the rail; however, referring to fig. 19, in some embodiments of the present invention, the track 13 of the air guiding pipe body 1 is provided with a groove 132 extending along the long axis direction X, and the assembling portion 211 of the partition 21 of the partition 2 and the connecting portion 311 of the base 31 of the fan 3 may be a flange. Therefore, the flanges of the assembling portion 211 and the combining portion 311 can be accommodated in the groove 132 of the rail 13, so that the assembling portion 211 and the combining portion 311 can be slidably combined with the rail 13 as well.

As described above, in some embodiments of the present invention, the track 13 of the air guiding pipe body 1 may be disposed on the inner circumferential wall of the air guiding pipe body 1, and as shown in fig. 20, when the track 13 is a convex portion, the air guiding pipe body 1 may be provided with a bump on the inner circumferential wall to form the convex portion; as shown in fig. 21, the air guiding tube 1 may also have two grooves 15 on the inner circumferential wall, the two grooves 15 are disposed adjacently and respectively extend along the long axis direction X, and each groove 15 is recessed toward the outer circumference of the air guiding tube 1, so that a convex portion of the rail 13 can be formed between the two grooves 15.

On the other hand, as shown in fig. 22, when the track 13 of the air guiding pipe body 1 is provided with a groove 132 extending along the long axis direction X, the air guiding pipe body 1 may be provided with two bumps on the inner peripheral wall to form the groove 132 between the two bumps; as shown in fig. 23, the inner peripheral wall of the air guiding tube 1 can also be directly recessed toward the outer periphery of the air guiding tube 1 to form the groove 132.

In summary, in the ventilation assembly of the airflow exchanging device according to the embodiments of the present invention, the track 13 is disposed inside the air guiding tube 1, and the fan 3 can be combined with the track 13, so as to improve the assembly convenience of the fan 3. Moreover, the ventilation assembly of the airflow exchanging device of each embodiment may further include a partition 2, and only the fan 3 may be directly coupled to the rail 13 through the coupling portion 311 of the base 31, so that the partition 2 does not need to be provided with a coupling portion for coupling the fan 3, and the effect of simplifying the structure of the partition 92 is indeed achieved. In addition, the separator 2 is composed of at least one partition 21, and the length of the separator 2 in the long axis direction X can be adjusted by only increasing or decreasing the number of the at least one partition 21, so as to be suitable for the air guide pipe bodies 1 with different lengths, and therefore, the separators 2 with different specifications do not need to be designed and manufactured in an open mold; on the other hand, the ventilation assembly of the airflow exchanging device of some embodiments includes two fans 3, the two fans 3 can be disposed in a staggered manner or aligned manner inside the air guiding tube body 1, and further the two fans 3 (and the partition 2) can be disposed in the air guiding tube bodies 1 with different lengths without providing partitions 2 with different specifications, thereby indeed having the efficacy of reducing the manufacturing and material preparation costs of the ventilation assembly.

Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes and modifications can be made by those skilled in the art without departing from the spirit and scope of the invention.
