Description

Air flow exchange unit

The present invention relates to an air flow exchange assembly for an air flow exchange device, and more particularly to an air flow exchange assembly for an air flow exchange device that allows the external space and the internal space to achieve a circulating ventilation function.

Referring to Fig. 1, there is disclosed a conventional airflow switching device 9 which can be mounted to a casing such as a building exterior wall or an electronic product. The air flow switching device 9 includes an air guiding tube body 91 and an air flow switching unit 92. The air flow switching unit 92 is disposed inside the air guiding tube body 91. The first end portion 911 and the second end portion 912 are respectively disposed in an outdoor space and an indoor space. The airflow switching module 92 includes a partitioning member 921 and two fans 922. The partitioning member 921 can divide the inside of the air guiding duct body 91 into two guiding spaces, and a fan 922 is disposed in each of the guiding spaces. Thereby, the air separation unit 92 composed of the partitioning member 921 and each of the fans 922 is configured to provide an airflow exchange function in the airflow switching device 9, so that the outdoor space and the air in the indoor space can circulate with each other.

In general, since the fan driving effect is positively correlated with the size of the fan wheel, the airflow switching module 92 of the conventional airflow switching device 9 tends to use a larger size fan 922 to provide better diversion ventilation. However, each of the fans 922 is disposed on the surface on both sides of the partitioning member 921. When the fan 922 having a larger size is selected, the air guiding duct body 91 is The pipe diameter must be expanded accordingly.

Furthermore, in some conventional airflow switching devices, the airflow exchange component may be further provided with a heat conducting component (for example, a heat dissipating fin), and the heat conducting component may penetrate the partitioning component of the airflow exchange component, so that the two ends of the heat conducting component are respectively Formed in the two flow guiding spaces. Thereby, the heat conducting member can provide a temperature equalizing effect to reduce the temperature difference of the two flow guiding spaces. However, in order to provide a better temperature conduction effect, the manufacturer tends to use a heat-conducting member having a larger size, and the diameter of the air-guiding tube body 91 must also be enlarged.

In other words, if the conventional airflow switching device 9 is to obtain a better ventilation and temperature conduction effect, the user must open a through hole having a large aperture at a wall or ceiling to install the air guiding body 91, resulting in correlation. The market acceptance of the product is low.

In addition, since the fan 922 in the two-conducting flow space must be electrically connected to the external power source via the wire, the wire space of the wire must be additionally reserved inside the air guiding pipe body 91 for accommodating the two. The wire to which the fan 922 is connected. However, as described above, the conventional airflow exchange device must have a larger diameter fan 922 or a heat conducting member to enlarge the diameter of the air guiding pipe body 91. If the air guiding pipe body 91 must also reserve a wiring space, further work is required. Expanding the diameter of the air guiding duct body 91 causes the size, cost and practicability of the conventional airflow switching device to obviously fail to meet market demands.
