Abstract
The invention provides a cooling device with an external circulation system and belongs to the technical field of machine design. The cooling device comprises a control body, a centrifugal shaft, a centrifugal cavity, a centrifugal body, a centrifugal spring, an arc plate and an elastic band. One end of a tension bar penetrates the upper wall face of an adjusting body and then is fixedly connected with the upper wall face of a mobile body together. The centrifugal cavity, the centrifugal body, the centrifugal spring, the arc plate and the elastic band are all arranged in the control body. One end of the centrifugal body is arranged in the centrifugal cavity and connected with the centrifugal shaft through the centrifugal spring. The other end of the centrifugal body is of an arc structure. The other end of the centrifugal body makes contact with the arc plate in a sealed manner. The elastic band is arranged on the outer surface of the arc plate. When the rotating speed of an engine is high, the mobile body moves upwards, and the exhaust gas recirculation rate of the engine is large; when the rotating speed of the engine is low, the mobile body moves downwards, and the exhaust gas recirculation rate of the engine is low. The cooling device is reasonable in design, simple in structure and suitable for optimization design of an exhaust gas bypass system.
