Problems solved by technology

When a certain fan 1 of the fan module fails and stops running, the window blade 121 closes the sash structure 12 due to gravity or inertia, preventing the system from recharging the air volume due to back pressure, causing the failed fan 1 to reverse and causing the overall reduced cooling capacity
[0003] However, the lack of setting of the sash structure 12 of the fan 1 is that: the sash 11 needs to add or re-make the corresponding fixing part 111 to install the sash structure 12 to increase the cost, and the sash structure 12 protruding from the sash 11 also requires additional work. The installation space, and the opening and closing method of the fan window structure 12 is limited by the arrangement of the fan module in the system, otherwise the window blade 121 cannot close the fan window structure 12 through gravity or inertia, so the fan window structure 12 cannot be closed. Design and use to achieve the best utility

Abstract

The invention discloses a fan, which is composed of an impeller, a motor and a fan frame. The motor is connected with and drives the impeller to rotate; the fan frame contains the impeller and the motor, as well as a frame body and a fan window structure which is connected with an air outlet side of the frame body and which is provided with a plurality of window leaf blades and a plurality of connecting pieces; and the connecting pieces respectively enable the window leaf blades to connect with corners of the frame body.

Description

technical field [0001] The invention relates to a fan and its fan frame, in particular to a fan with a fan window structure and its fan frame. Background technique [0002] At present, the computer system is becoming more and more complex, so the heat dissipation requirements of the fans are also increasing. If the fan fails and stops at the system end, the back pressure inside the system will cause the air volume to recharge, causing the failed fan to dissipate the air volume. , reducing the cooling capacity of the fan. Please refer to Fig. 1, the prior art uses louvers designed on the air outlet side of the fan frame to solve this problem, a kind of existing fan module includes a plurality of fans 1, each fan 1 includes a fan frame 11, a The impeller 13 and a motor (not shown). A window structure 12 is arranged on the air outlet side of each fan frame 11, and the fan window structure 12 has three window blades 121, and a fixing part 111 is added on the fan frame 11 to in...
