Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the present invention.

Example 1

As shown in fig. 1 and 2, the present embodiment provides an exhaust device for a condenser air duct, which includes a flow guiding channel 1, a frame body 2, an exhaust louver 3, a flow guiding plate 4 and a power device 5, wherein the flow guiding channel 1 is disposed at an air outlet of the condenser air duct and is used for guiding an air flow to be exhausted from the air outlet of the condenser air duct to the flow guiding plate 4; the frame body 2 is arranged on the drainage channel 1 and used for installing the exhaust louver 3, the exhaust louver 3 is movably connected to the hollow position of the frame, the exhaust louver 3 is used for conducting drainage on airflow at the tail end of the drainage channel 1, at least two curtain leaves 31 are arranged on the exhaust louver 3, the two curtain leaves 31 are connected through a linkage part 7, and when one curtain leaf 31 rotates, the linkage part 7 drives the other curtain leaf 31 to rotate; the power device 5 is arranged on one side edge of the frame body 2, the power device 5 is used for controlling the rotation of the exhaust louver 3, the output end of the power device 5 is provided with a swing arm 6, one end of the swing arm 6 is connected to the louver 31, and the swing arm 6 drives the louver 31 to rotate to change a certain angle; guide plate 4 establishes at drainage channel 1 end, and guide plate 4 carries out the water conservancy diversion to exhaust air current, and guide plate 4 has certain camber and two guide plate 4's convex surface sets up relatively, and when the exhaust air current contacted the convex surface face of guide plate 4, changes original direction of motion, changes the tendency along with the convex surface flows in, plays the effect of drainage, increase exhaust flow.
