The solar heat collector device is an important part of the solar equipment. In the solar heat collector devices, hydraulic system has a wide range of application because of its smooth running and strong adaptability. Based on analyzing the movement rule of the sun and the structure and work process of the heat collector device, a hydraulic control system was designed aiming at the heat collector device, and its simulation model was built in AMESim software to make simulated analysis. The simulation results verify the design is practical in theory. Thereby it lays foundation for the production and application of the next step.
