Heat-radiating device with composite radiation efficiency

Abstract

The heat-radiating device with composite heat radiation efficiency includes a foundation with a heating surface and a radiating surface. The foundation has an inner space for inserting phase-changing materials. A heat pipe includes a heat-absorbing end placed into the foundation and a radiating end protruded out of the foundation. A radiating fin set is arranged onto the radiating end of the heat pipe. The heat-radiating device enables the heat absorbed by the foundation to be quickly guided out of the foundation through the heat pipe. The radiation area is increased by the radiating fin set for improved heat radiation efficiency. The phase-changing material assists in heat absorption and storage by latent heat, thereby avoiding overheating of foundation and also helping to control efficiently the heat peak of the foundation. Furthermore, the heat-radiating device has a composite heat radiation effect with improved applicability.
