Abstract
The invention provides a flow guiding device which is arranged on a fan array of a server. The fan array is provided with at least two fans arranged in parallel, and is used for generating air flow so as to radiate at least one heat source in the server. The flow guiding device comprises a pivot and a flow guiding body, wherein the pivot is arranged between the two fans, and the flow guiding body is connected with the pivot and driven to swing by taking the pivot as the axis due to the air flow generated by the fan array. In the flow guiding device, when one fan in the fan array becomes invalid, flow guiding liquid can swing to the invalid fan by fully utilizing driving force generated by the backflow air flow so as to prevent the air flow generated by the fan array from flowing back to the invalid fan, thereby ensuring the normal running of the server, and saving the space and the manufacturing cost of the server.
