PURPOSE: A device for tracking sunlight using heat-expandable fluid is provided to track the sunlight regardless of installment place by adopting solar heat and the heat-expandable fluid as driving source for rotating a panel for collecting the sunlight. CONSTITUTION: A supporting pillar is fixed to a ground. A swing shaft(20) is supported by the supporting pillar to be rotatable. A panel for collecting sunlight(30) is integratedly rotated with the swing shaft. A pair of light receiving units transfer collected sunlight to a heat-expandable fluid(F). A pair of heat-expandable cylinder(50) is connected with the inside of the light receiving units. A power transmission unit rotates the panel for collecting the sunlight according to the direction of the sun. |
