Abstract:
1. A heat dissipation control system of a portable electrical device having a first body and a second body, comprising: an angle detection module, sensing an included angle of the first body and the second body and generating an angle signal corresponding to the included angle of the first body and the second body, the angle detection module comprising: at least one position detection element arranged in the second body, wherein when the first body moves relative to the second body, the at least one position detection element generates a position signal corresponding to the relative position between the first body and the second body; a light emitting element emitting a light ray; and an optical sensor arranged in the second body for sensing the light ray, wherein the optical sensor generates the angle signal according to the sensed light ray; and an angle detector arranged in the first body, wherein the angle detector generates the angle signal in response to the position signal; and a control module, in response to the angle signal, generating a heat dissipation control signal according to the angle signal for enabling at least one of a first heat dissipation policy and a second heat dissipation policy.
