Description

TECHNICAL FIELD

[0001] The utility model relates to the field of precision instrument processing, especially a notebook bottom plate of high -efficient heat dissipation. BACKGROUND

[0002] The heat dissipation hole of the notebook computer is an important structure designed to improve the heat dissipation efficiency. The heat dissipation hole is usually located at the bottom and side of the notebook, and its role is to allow external air to enter the notebook interior, take away the heat generated by components such as processors and graphics cards, and discharge hot air to the external environment. The design of the heat dissipation hole is crucial to the performance and stability of the notebook, because overheating can cause hardware performance to decline, and even damage.

[0003] When designing the heat dissipation hole of the notebook, the manufacturer will consider various factors, including the size, number, position of the heat dissipation hole, and the cooperation with the internal heat dissipation components. For example, some notebooks may be designed with large-area mesh holes at the bottom to provide more air inlet area, while additional heat dissipation holes are set on the side to increase the air outlet volume. In addition, some high-end notebooks may use special heat dissipation technology, such as liquid cooling or double-fan configuration, to further improve the heat dissipation performance. In order to maintain the heat dissipation efficiency of the notebook, the user should regularly clean the heat dissipation hole to avoid dust and debris blocking these holes. At the same time, when using the notebook, it should be placed on a soft bed, blanket or other heat-insulating object to avoid affecting the ventilation effect of the heat dissipation hole.

[0004] However, the existing notebook computer often encounters the following problems in use: when the existing notebook computer is placed on the desktop, the heat dissipation hole at the bottom is blocked by the desktop, causing the hot air to be unable to smoothly discharge, thereby greatly reducing the heat dissipation effect.
