Description

Fan module and its fan frame

The present invention relates to a heat sink, and more particularly to a fan module.

A fan is an important heat sink in a computer device. As computer devices become more and more demanding for heat dissipation, there are fan modules composed of multiple fans. A fan module typically has a frame to accommodate a plurality of fans assembled therein. At present, most of the fans use the interference force of the connector to insert and unplug as the main clamping force mounted on the frame. Some computer devices use the upper cover of the housing to press the fan into the frame. If the size of the fan module is smaller than the height of the computer case, so that the upper cover cannot touch the fan module, this method cannot suppress the fan from being fixed in the frame. However, the interference force of the connector can only be removed from the frame in the case of severe vibration, which is a problem to be solved.

It is therefore an object of the present invention to provide an improved fan module and fan frame therefor.

According to the above object of the present invention, a fan module is provided, which comprises a frame, a plurality of fans, a fixing frame and a locking frame. The frame has a plurality of accommodation spaces and two pairs of shell walls. A plurality of fans are respectively located in the accommodation spaces. The fixing frame has a first interference unit, and the two ends of the fixing frame are respectively pivoted Connected to one of the pair of shell walls, the holder can be rotated against the frame to press or leave the fans. The locking frame has a second interference unit and is located in one of the other pair of wall walls. When the first interference unit is engaged with the second interference unit, the fixing frame presses the fans.

In accordance with the above objects of the present invention, a fan frame is provided that includes a frame, a mounting bracket, and a locking bracket. The frame has at least two pairs of shell walls and a plurality of receiving spaces for respectively mounting fans therein. The fixing frame has a first interference unit, and two ends of the fixing frame are respectively pivotally connected to one of the pair of shell walls, so that the fixing frame can rotate against the frame to press or leave the fans. The locking frame has a second interference unit and is located in one of the other pair of wall walls. When the first interference unit is engaged with the second interference unit, the fixing frame presses the fans.

Therefore, the fan module and the fan frame of the present invention are used to securely fix the fans in the frame by the fixing frame pivotally connected to the frame, instead of merely intervening the interference force of the connector as the main card mounted on the frame. Together, it can withstand stronger vibrations.

Please refer to FIG. 1 , which illustrates a fan module in a state in which the fixing frame is not locked and a fan is disassembled from the frame according to a preferred embodiment of the present invention. The fan module 100 is basically composed of a frame 102 and a plurality of fans 110. The frame 102 has a plurality of receiving spaces 116 to house the fan 110 therein. The accommodating space 116 has a connector 120 electrically connected to the connector 110a of the fan 110, so that the fan 110 can obtain electricity therefrom. Run from the source. The connectors 120 in all of the receiving spaces 116 are electrically connected to the connectors 102a or 102b outside the frame 102, and are connected to a power supply or other external power source by the connectors 102a or 102b.

When all the fans 110 are respectively mounted to the plurality of accommodation spaces 118b of the frame 102, the state as shown in FIG. 2 is obtained. The fan 110 can be operated by taking power from the connector 102a or 102b of the fan module 100. A pair of substantially parallel shell walls (103a; 103b) of the frame 102 respectively have an air inlet window 118a and an air outlet window 118b for allowing airflow caused by the fan 110 to circulate.

The frame 102 has a mounting bracket 104 to securely secure all of the fans 110 within the frame 102 at a time. Both ends of the holder 104 are respectively coupled to a pair of substantially flat shell walls (103c; 103d) of the frame 102 by pivots 104a, so that the holder 104 can be rotated relative to the frame 102. When the fixing frame 104 is rotated to be able to press all the fans 110, the fixing frame 104 is engaged with the locking frame 122 to form a locked state (as shown in FIG. 3). When the fixing frame 104 rotates and disengages from the locking frame 122 (as shown in FIG. 2), the fan 110 in the locking frame 122 can be pulled out (as shown in FIG. 1). In the present embodiment, the fixing frame 104 is a "symbol shape", but the fixing frame 104 is not limited to the "symbol shape", as long as the shape or structure of all the fans 110 can be simultaneously pressed. The locking frame 122 is located on the shell wall 103b. The fixing frame 104 further has a plurality of buffering members 104c (for example, elastically preferable materials). When the fixing frame 104 is rotated to resist all the fans 110, the buffering members 104c directly contact the fan 110 to make the fan 110 and the fixing frame 104. Will not rub each other. When the fixing frame 104 is rotated to be able to press all the fans 110, the fixing frame The interference unit of 104 (e.g., the projection 105 at the elastic piece 104b) is engaged with the interference unit (e.g., the opening 122a) of the locking frame 122 to form a locked state (as shown in Fig. 3).

The projection 105 of the elastic piece 104b has two abutting faces: a vertical surface 105a and an inclined surface 105b. The vertical surface 105a is vertically connected to the surface of the elastic piece 104b, and the inclined surface 105b is not perpendicularly connected to the surface of the elastic piece 104b. The function of the inclined surface 105b is to help the projection 105 to easily slide into the opening 122a of the locking frame 122. The function of the vertical surface 105a is to make it difficult for the projection 105 to be detached from the opening 122a. When the protruding portion 105 of the elastic piece 104b is to be disengaged from the opening 122a of the locking frame 122, the user only needs to pull the elastic piece 104b in the direction of the arrow 108, and the protruding portion 105 will be separated from the opening 122a, and then the fixing frame 104 can be The condition shown in Fig. 2 is rotated to disengage from the lock frame 122.

According to the preferred embodiment of the present invention, the fan module and the fan frame of the present invention are used to securely fix the fans in the frame by the fixing frame pivotally connected to the frame, instead of merely intervening by the connector. As the main clamping force installed in the frame, the force can withstand stronger vibration conditions.

Although the present invention has been described above in terms of a preferred embodiment, it is not intended to limit the invention, and it is obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention. The scope of the invention is defined by the scope of the appended claims.
