Notebook computer base plate integrating heat dissipation and electromagnetic shielding

Abstract

The invention relates to the technical field of electromagnetic shielding, in particular to a notebook computer base plate integrating heat dissipation and electromagnetic shielding. The base plate comprises a base plate body, the upper plate face of the base plate body is provided with an upper cavity, the lower plate face of the base plate body is provided with a lower cavity, the cavity bottomfaces of the upper cavity and lower cavity are provided with through ventilation holes; one side edge of the lower cavity is hinged to a fan disk, the fan disk rotates around a hinge shaft to a containing position in the lower cavity or a position forming an included angle with the base plate body, a supporting unit is arranged between the fan disk and the lower cavity and used for supporting theincluded angle state between the fan disk and the base plate body; a foamed aluminum plate is laid in the upper cavity, and the foamed aluminum plate is provided with through holes penetrating the plate face of the foamed aluminum plate; the fan disk used for heat dissipation is in hinged connection with the base plate body, and the electromagnetic shielding action of the foamed aluminum plate isused for shielding the electromagnetic radiation of the bottom of the notebook computer; not only can the heat dissipation be conducted on the notebook computer, but also the electromagnetic radiationcan be shield, so that the effect of killing two birds with one stone is achieved.

Description

technical field [0001] The invention relates to the technical field of electromagnetic shielding, in particular to a notebook computer backing plate which integrates heat dissipation and electromagnetic shielding. Background technique [0002] The circuit board in the electronic equipment will emit high-frequency electromagnetic waves when it is working, which will interfere with the normal operation of adjacent electronic products. At the same time, the electromagnetic waves will radiate to the outside, which may cause harm to the human body. For example, the laptop computer that is often used in people's daily work, the work of the computer motherboard, the operation of the cooling fan, etc., will produce various radiations, which is a threat to people's health, especially to pregnant mothers. my country's electromagnetic radiation safety and health standard limit is less than 40 microwatts per square centimeter. The electromagnetic radiation of notebook computers is const...

AI Technical Summary

Problems solved by technology

Using an old laptop computer for a long time, its electromagnetic radiation will accelerate the death of human cells, inhibit the generation of new cells, and even cause cell deformity, which will lead to very serious consequences for pregnant mothers

[0003] In the prior art, shielding devices are often used to cover circuit boards and the like to achieve the purpose of shielding electromagnetic waves, and most of the existing shielding covers are plate-type structures. Although this technical solution can achieve the effect of shielding electromagnetic radiation, However, installing shielding devices on the outside of many circuit boards will undoubtedly increase the occupied volume of circuit boards and other equipment, resulting in an increase in the volume of electronic equipment, which is contrary to the development trend of thinner and lighter electronic equipment.
