The present disclosure relates to a fan module, in particular to a wind direction changing structure specially designed for a fan with a bidirectional operation to maintain a high operating efficiency of the fan.
In general, a computer system of an electronic product uses a cooling fan to dissipate heat. In the heat dissipating operation of the cooling fan, the cooling fan is rotated in a predetermined rotating direction to guide external air into the electronic product and dissipate the heat of a heat source to the outside. Since a large quantity of external air is guided into the electronic product, therefore dust may be accumulated in the electronic product easily, particularly in a special environment (such as a factory). At the beginning of starting the operation of the electronic product, the cooling fan is generally controlled to be rotated in a predetermined rotating direction for a period of time in order to guide the dust from the interior of the electronic product to the outside by the cooling fan, or after the cooling fan has been operated for a period of time, a reverse rotation is performed to remove the dust from the interior of the electronic product.
In the bidirectional rotation technology of the conventional fan module this sort as shown in
Although the aforementioned bidirectional rotation technology of the conventional fan module can achieve the forward/reverse rotation effect of the fan module 92, such technology still has the following drawbacks. For example, the fan module 92 guides airflow mainly by rotating the plurality of vanes 921, so that the design of the shape, radiant and curvature of the vanes 921 is fixed, and various different designs of the vanes are provided for a single rotating direction. In other words, the vanes have the optimal design of the shape, radiant and curvature for the single rotating direction, and thus the airflow guidance function of the vanes cannot be maximized when the vanes are used for rotations in an opposite direction. The airflow guidance efficiency may be reduced significantly during the rotation of the vanes, or vibrations and noises may even be produced. Obviously, such conventional fan bidirectional rotation design is not a very good solution.
In another conventional fan module bidirectional rotation technology as disclosed in R.O.C. Pat. No. TW 1556568 entitled “Forward/reverse rotation driving control circuit for a single-phase brushless DC fan motor”, the technologies similar to this patented technology also use a control circuit to control the forward/reverse rotation of a fan directly, and thus also have the same drawback of the bidirectional rotation of the vanes as described above and require further improvements. Obviously, it is a main subject for related manufactures to overcome the aforementioned drawback of the conventional fan module of the bidirectional operation.
In addition, the conventional fan extraction module does not come with a structural design for removing the original fan module and then turning the original fan module upside down and reinstalled, and thus the conventional fan extraction module has the drawback of the inconvenient removal and installation that requires a tool for the removal and installation.
In view of the aforementioned drawbacks of the prior art, the discloser of the present disclosure based on years of experience in the related industry to conduct research and experiment, and finally developed a wind direction changing structure with a high fan operation efficiency to overcome the drawbacks of the prior art.
It is a primary objective of the present disclosure to provide a wind direction changing structure of a fan capable of providing bidirectional airflow operations while maintaining a single-direction airflow operation of the cooling fan module, protecting the vanes appropriately and featuring a quiet operation, so as to achieve the effects of assuring the quality and improving the service life of the product.
To achieve the aforementioned and other objectives, the present disclosure provides a wind direction changing structure, comprising: a main body, having a fan casing with an accommodation space formed therein, a fan connecting seat disposed on a side of the fan casing, and a first socket and a second socket formed on the fan connecting seat and electrically coupled to a fan forward rotation control circuit; at least one fan module, having a fan plug disposed at the bottom thereof; wherein the fan plug of the fan module is plugged into the corresponding first socket, and after the fan module has rotated 180 degrees, the fan plug is plugged into the corresponding second socket, and a fan of the fan module is maintained to be rotated in the same.
In this embodiment, the fan connecting seat comprises a conductive socket and socket panel.
In this embodiment, the conductive socket has an installation slot formed at the top thereof and communicated to an installation space inside the conductive socket.

In this embodiment, the fan plug is biased relative to a center line of the fan module.
In this embodiment, the fan module comprises a fan casing and the fan installed in the fan casing, and the fan comprises a plurality of vanes.
To make it easier for our examiner to understand the technical content of the disclosure, we use preferred embodiments together with the attached drawings for the detailed description of the disclosure.
With reference to
The fan module 20 comprises a fan casing 21 and a fan 22 installed in the fan casing 21, a fan plug 23 disposed on a side (such as the bottom) of the fan casing 21 (or the fan module 20), a conductive connecting post 231 protruding from the fan plug 23. In an embodiment, the fan plug 23 is biased relative to the center line of the fan casing 21 (or the fan module 20). In other words, the fan plug 23 is not disposed on the center line of the fan casing 21 (or the fan module 20), but this disclosure is not limited to such arrangement. The fan casing 21 (or fan module 20) has at least one quick release pin 24 disposed on both sides of the bottom thereof, and the quick release pin 24 has two quick insert slots 241. Wherein, the quick insert slot 241, the quick release engagement slot 143, and the quick release member 132 constitute a quick release assembly. The fan 22 comprises a plurality of vanes which comes with the design of general vanes and has the optimal design including the shape, radiant, and curvature for the airflow of single rotations, so as to provide a very good effect of guiding the rotating airflow.
During the assembling process of the wind direction changing structure of the present disclosure as shown in
In the dust removal operation, it is necessary to discharge the dust or waste gas from the main body 10 (or the fan casing 11) to the outside. In
In the wind direction changing structure of the present disclosure, the air blowing direction of the fan module can be set flexibly and the fan module can be plugged and unplugged directly to reduce the assembling time and labor, and components can be shared to lower the cost.
