Description of the Invention: [Technical Field] The present invention relates to a fan and a fan frame thereof, and more particularly to a fan having a fan window structure and a fan frame thereof. [Prior Art] At present, the computer system is increasingly complicated, so the heat dissipation requirement for the fan is also increased. If the fan fails to stop at the system end, the internal pressure of the system will cause the air volume to be recharged, causing the failed fan. Instead, the air volume is lost and the heat dissipation capability of the fan is reduced. Please refer to the figure, the conventional technology is applied to the air outlet of the fan frame to solve the problem. A conventional fan module includes a plurality of fans 1 , and each fan 1 includes a frame u , a base 13 and a motor (not shown). A window structure 12 is provided at the air outlet of each of the frame frames u. The fan window structure 12 has three window leaves 121, and the outer frame-fixing portion of the fan frame u is provided to mount the window leaf 121. When a certain failure of the fan module: 1: occurs, the window 121 closes the window structure 12 due to gravity or inertia, thereby preventing the system from being recharged due to back pressure, resulting in the reversal of the failed fan 1 The overall heat dissipation is low. • However, the fan window structure 12 of the fan 1 is missing in that the fan frame needs to be externally or re-made to make the corresponding fixing portion m to install the fan window structure 12, so that the cost is increased, and the fan window structure 12 protrudes from the fan frame. Additional installation space is required, and the opening and closing of the window structure 12 is large. The 1322659 type is limited by the fact that the fan module cannot be protected by gravity or inertia in the system; the structure of the fan window structure 12 is used. To achieve the best: use to change == for a fan with a fan window structure and its fan frame

In addition, the heat dissipation effect of the entire fan is maintained to reduce the production cost and the required installation space. The edge is that, in order to achieve the above object, a frame frame frame body according to the present invention is connected to the frame body and forms a frame. An opening, and a window structure. The fan window structure is coupled to the frame body, and has a plurality of window leaves and a plurality of connecting members, wherein the connecting members respectively connect the window leaves to the corner of the frame body. The shape corresponds to the shape of the opening. To achieve the above object, a fan according to the present invention includes an impeller, a motor and a frame. The motor is coupled to drive the impeller to rotate; The motor includes a frame body, a motor base, the motor base is coupled to the frame body to form an opening, and a window structure, the window window structure is coupled to the opening of the frame body, and the fan window structure has a restored window leaf and 322659 a plurality of connecting members, wherein the connecting members respectively connect the window leaves to the corners of the frame, and the shape of the window leaves when closed is corresponding to the shape of the opening. The invention has a window according to the invention. The structure fan and its fan frame connect the window leaf of the fan window structure to the corner of the frame body, so that the fan j structure and the frame body are integrated and designed, so there is no need to increase the volume of the frame body, and the installation or the m-shaped window structure is not required. The component of f simplifies the structure and manufacture of the fan frame. Compared with the prior art, the present invention only needs to modify the corner of the opening of the frame. The rest of the frame still retains the existing structure, and the window leaf is backed by the inside of the system. (4) Closing 'Therefore, it is not limited to the position and direction in which the fan is installed in the system, and it can (4) maintain the fan window structure, thereby maintaining the overall heat dissipation performance of the fan, reducing the production cost and the required installation space. .the following Referring to the related drawings, a fan having a fan window structure and a fan frame thereof according to a preferred embodiment of the present invention will be described, wherein the same elements will be described with the same reference numerals. Please refer to FIG. 2 and FIG. A fan 2 of the preferred embodiment includes a base %, a motor (not shown), and a frame 20. The fan 2 can be an axial fan or a centrifugal fan, and the motor is coupled to and drives the fan. An impeller (not shown) rotates; the fan frame 20 houses the impeller and the motor, and includes a frame 21 and a base 30. The base 30 is coupled to the frame 21 and a window structure 22 is disposed on the base. The window structure 22 is preferably located at the opening 211 of the fan frame 20. The window structure 2 is connected to the space near the fixing holes of the four corners of the frame 21 1322659, the window The structure 22 has a plurality of window 221 and a plurality of connecting members 222. Each of the window 221 is integrally formed with each of the connecting members 222, and the connecting member 222 connects the window 221 to the corner of the frame 21, respectively. Its connection method is, for example, but not for pivoting, Binding bonding or snap, when the vane 221 is closed, which ^ 2U shape corresponding to the opening line '3〇 shielding material can be reduced at the base, while reducing the volume thereof. Further, the frame 2〇 can be divided into a circumferential portion 213 and an outer expansion portion 2U, and the frame 20t includes a guide vane 4 seat 30 and a circumferential portion 213. . Yuliang fan 2 is installed in the system, and the operation of the fan window structure 22 is as follows: "When the fan 2 is in normal operation, the window tm system: the heart is facing the culvert a 疋 疋 · "Kai Ma% to the second: when the system fan 2 When a fault occurs or stops, other normal fans of the system continue to operate and cause a system to make the window leaf 22 of the window structure 22 cover the opening 211 to prevent: closing and closing the windows ^ , ^ Prevent turbulent recirculation, so it can maintain the season == heat dissipation performance. As shown in Figure 3, the fan window and its fan frame of the fan window in Fig. 2, the 脔簦 basin (10)... = Π 221 only covers the opening 211 and does not cover the base 3 ,, · does not protrude above the plane of the frame 2 应 'frame 2 〇 opening 211.乂 and the maximum angle at which the fan is lowered to limit the opening of the window leaf 221, the maximum angle: i::2 at: degrees; the limiting member 212 can be integrally formed with the connecting member 222 1 s limiting member 212 The fan 2 of the frame 21 is operated and the vane 221 is connected by a link from the center of rotation. =: When opening, the restriction member 212 restricts the opening of the window leaf (3): 90 degrees or less, to avoid the window leaf 221 being closed by the system back pressure due to the opening angle being too large. In summary, the fan having the fan window structure and the window leaf of the window structure are connected to the corner of the frame body, so that the fan wide structure and the frame body are integrated, so there is no need to increase the frame body. The volume is free of the components required for the ampule or solid window structure, simplifying the structure and manufacture of the fan frame. Compared with the prior art, the present invention only needs to modify the corner of the opening of the frame. The rest of the frame still retains the existing structure, and through this design, the shape of the window leaf can be corresponding to the shape of the opening, and the material of the window leaf The cost is reduced, and the window leaf can be closed by the back pressure inside the system, so it is not limited to the position and direction in which the fan is placed in the system. _. Ensure that the window structure is closed, thereby maintaining the overall heat dissipation performance of the fan. Reduce production costs and installation space required. The above is intended to be illustrative only and not limiting. Any equivalent modifications or changes made without departing from the spirit and scope of the invention are intended to be included in the scope of the appended claims.
