Abstract

The invention discloses a notebook computer heat radiation system based on tablet loop heat tubes. The notebook computer heat radiation system comprises a tablet loop heat tube evaporator, a screen back plate heat radiator, a keyboard bottom plate heat radiator and a tablet evaporator, wherein the tablet loop heat tube evaporator is clung to a computer CPU (Central Processing Unit) chip; steam flows through the screen back plate heat radiator through a pipeline, and then heat is diffused and condensed into a liquid through natural air convection; the liquid flows to the tablet evaporator which is clung to a display card GPU (Graphics Processing Unit) chip and is evaporated into steam; the steam flows to the keyboard bottom plate heat radiator through another pipeline and is cooled into a liquid through natural air convection, and then the liquid flows back to a liquid reservoir of the tablet loop heat tube evaporator. By adopting the heat radiation system, internal layout of a notebook computer is facilitated, a mounting space is effectively reduced, noise caused by a fan can be eliminated as fans and heat radiator components are not used, electric power consumption is reduced, and the standby and lasting time of a computer is prolonged.
