Heat relay mechanism and heat-dissipating fin unit

Abstract

A heat relay mechanism includes a heat-dissipating member for dissipating heat, a buffer member contacted with the heat-dissipating member at a first surface, a thermally deformable member connected to a second surface of the buffer member and deforms at a high temperature, a heat pipe connected to the thermally deformable member at one end, and a device connected to another end of the heat pipe.
