Abstract

A radiation structure is employed in electronic apparatus such as a laptop computer having a body containing a heat generating element (e.g. CPU) and a display, rotatably connected to the body. The radiation structure transfers heat from the CPU to the outside of the apparatus and includes a first heatpipe; a hinge member connected to the host heatpipe for receiving heat therefrom; a second heatpipe for transferring heat from the hinge member to a radiation member placed in the display, one end of the second heatpipe being arranged substantially coaxially with the center of rotation of the display; and a sleeve member arranged in the hinge member coaxially with respect to the center of rotation of the display, the sleeve member being inserted from the outside into the inside of the display together with a portion of the second heatpipe which projects from the hinge member.
