Heat-radiating device

Abstract

The present invention provides a heat-radiating device comprising a motor, a link mechanism, a first cylinder, a second cylinder, and a heat regenerator. The link mechanism is disposed at the output end of the motor. The heat regenerator is connected at rear ends of the first cylinder and the second cylinder, respectively. A first link is disposed between a first piston in the first cylinder and the link mechanism. One side on the outer wall of the first cylinder is a heated end. A second link is disposed between a second piston in the second cylinder and the link mechanism. A heat-radiating element is disposed on an outer wall of the second cylinder. When the motor rotates, alternating and reciprocating circulation of gas in the first and second cylinders is driven via the link mechanism to conduct an external heat source from the heated end to the heat-radiating element.
