Problems solved by technology

However, in the prior art, the ventilation area at the air outlet of the notebook computer cannot be changed. In order to dissipate the heat quickly, the usual method is to set a fan at the air outlet, or reduce the frequency of the notebook computer CPU itself.
Since the ventilation area at the air outlet cannot be changed, the above method still has unsatisfactory heat dissipation, which affects the performance and service life of the notebook computer.

Abstract

The invention discloses a method for dissipating heat of a notebook computer. The method comprises the steps that a lower shell of the notebook computer is arranged, and one side face of the lower shell is provided with a window; a heat sink provided with a plurality of air outlets is arranged; the heat sink provided with the air outlets is arranged at the window of the lower shell to form a multi-channel radiator dissipating heat outwards; the wind temperature of the multi-channel radiator is detected to obtain a heat dissipation temperature value; according to the heat dissipation temperature value, the opening degrees of the air outlets of the heat sink of the multi-channel radiator are adjusted. The invention further provides a device applied to the method. The device is simple in structure and convenient to use; when the notebook computer produces a great amount of heat due to a high load, the opening degrees of the air outlets of the notebook computer can be adjusted, so the cross sectional areas of the air outlets are increased, outward heat dissipation is accelerated, it is guaranteed that the notebook computer can be used normally, and the service life of the notebook computer is prolonged. In addition, the invention further provides a method for achieving heat dissipation of the notebook computer through the device.

Description

technical field [0001] The invention relates to the technical field of notebook computers, in particular to a method and device for realizing cooling of notebook computers. Background technique [0002] When a user is using a laptop, the heat generated by the laptop is different due to different loads. When a lot of heat is generated, only by dissipating the heat quickly can the normal use of the laptop be ensured. However, in the prior art, the ventilation area at the air outlet of the notebook computer cannot be changed. In order to dissipate heat quickly, the usual method is to arrange a fan at the air outlet, or reduce the frequency of the notebook computer CPU itself. Since the ventilation area at the air outlet cannot be changed, the above method still has unsatisfactory heat dissipation, thereby affecting the performance and service life of the notebook computer. Contents of the invention [0003] The object of the present invention is to solve the above problems a...
