Embodiment Construction

[0012] Certain terms are used in the claims and description to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The claims and description do not use the difference in name as the way to distinguish components, but the difference in function of the components as the criterion for distinguishing. The "comprising" mentioned in the claims and the specification is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means. .

[0013] Please refer to figure 2 , figure 2 It is a s...

Abstract

The present invention provides a thermal control method and a thermal control system. The thermal control method comprises: detecting a temperature variance of a component of the electronic device to generate a detecting result; and determining a temperature threshold value for the integrated circuit as a throttling point according to the detecting result. The thermal control method and thermal control system can prevent the surface of an electric device from being excessive heating, so that the electric device can realize better CPU performance, better adapt to environmental change and possess better dynamic temperature management.

Description

technical field [0001] The present invention relates to a thermal control method and a temperature control system, in particular to a thermal control method and a temperature control system that can better adapt to environmental changes and have better dynamic temperature management. Background technique [0002] Please refer to figure 1 , figure 1 It is a timing chart for the temperature control method of the existing mobile phone. Such as figure 1 As shown, the existing temperature control method only detects the current temperature of the system on chip (System on Chip, SoC) of the mobile phone, and when the current temperature of the SoC reaches 90°C (that is, the current limiting point (throttlingpoint)), the existing temperature control method The method begins throttling (ie, reducing the frequency of the CPU). Therefore, in the existing temperature control method, the throttling process is very fast and the throttling degree is very large. for example, figure 1...
