Fan duct

Abstract

A fan duct includes a main body bounding an airflow path, a divider extending from the main body to divide the airflow path into first and second airflow paths, and a baffle. A first end of the baffle is pivotably fixed to the main body and connected to the divider, a second end of the baffle opposite to the first end rotates about the first end to adjust the airflow into the first and second airflow paths. The second end of the baffle may be located in the airflow inlet.

What is claimed is: 
     
         1 . A fan duct, comprising:
 a main body bounding an airflow way, the airflow way comprising an air inlet and an air outlet opposite to the air inlet;   a divider extending from the main body along a direction from the air inlet to the air outlet, to divide the airflow way into first and second airflow ways; and   a baffle, a first end of the baffle pivotably fixed to the main body and connected to the divider, a second end of the baffle opposite to the first end being operable to be rotated about the first end to adjust the airflow into the first and second airflow ways, the second end of the baffle located at the air inlet.   
     
     
         2 . The fan duct of  claim 1 , wherein the main body is formed by a first duct coupling to a second duct. 
     
     
         3 . The fan duct of  claim 2 , wherein the first duct comprises a first main plate and a first side plate extending from a first side of the first main plate, the second duct comprises a second main plate and a second side plate extending from a first side of the second main plate, second sides of the first and second main plates are coupled together, thereby the airflow way is bounded by the first and second main plates, and the first and second side plates. 
     
     
         4 . The fan duct of  claim 3 , wherein the divider extends from the second side of the first main plate. 
     
     
         5 . The fan duct of  claim 4 , wherein two posts extend from the first end of the buffer, a pivot hole is defined in the first main plate of the first duct adjacent to one end of the divider, a pivot portion extends from the one end of the divider adjacent to the air inlet, the posts of the buffer are pivotably engaged in the pivot hole and the pivot portion. 
     
     
         6 . The fan duct of  claim 5 , wherein an arc-shaped slot is defined in the first main plate and about the pivot hole, a fastener extends through the slot to engage in the second end of the baffle. 
     
     
         7 . The fan duct of  claim 3 , wherein an adjusting portion is formed at the second side of the first main plate of the first duct, a hook is formed at the second side of the second main plate of the second duct, the hook is locked to the adjusting portion. 
     
     
         8 . The fan duct of  claim 7 , wherein the adjusting portion is substantially a gear rack and defines a plurality of slots, the hook of the second duct comprises a block to engage in one of the plurality of slots.
