Heat-radiating structure

摘要

A heat-radiating structure includes a closed container connected to an end of a thermal pipe that is connected at another end to a heat source. The closed container is made of a heat-conductive material and filled with heat-absorptive ethanol. Outer wall surfaces of the closed container may be provided with parallel ribs or other raised portions in different patterns to increase the contact area of the closed container with ambient air and thereby speed up heat radiation from the closed container. No other power-consuming cooling fan is needed to help the heat radiation from the closed container into the ambient environment.
