Problems solved by technology

However, since the thermal conductivity of common metals is up to about 300W / m·K, and the graphite film is up to about 1000W / m·K, when the CPU power consumption is getting higher and higher, metal or graphite films often cannot meet the heat dissipation requirements of mobile phones. requirements, the surface temperature of the mobile phone will exceed the comfortable temperature perceived by the human body when running a large program load, which will affect the user experience; at the same time, the service life of the mobile phone will also be affected if it is in a high temperature state for a long time

Abstract

Embodiments of the present invention provide a heat dissipation device and electronic equipment, wherein the heat dissipation device specifically includes: a metal heat dissipation middle frame; wherein, the metal heat dissipation middle frame is a hollow and airtight structure, and the inner seal of the metal heat dissipation middle frame is easily Volatile liquid. The embodiment of the present invention can avoid the situation that the temperature of the local area of ​​the electronic equipment is too high due to heat concentration, and achieve better heat dissipation effect.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a heat dissipation device and electronic equipment. Background technique [0002] With the continuous development of electronic technology, most of the CPUs of mobile phones and other electronic devices are developing towards multi-core. However, with the continuous improvement of mobile phone performance, the problem of heat generation is becoming more and more serious; , making the heat dissipation space of the mobile phone smaller and smaller, therefore, the heat dissipation of the mobile phone under the condition of limited heat dissipation space becomes particularly important. [0003] Most of the existing solutions use metal or graphite film to dissipate heat from the mobile phone. However, since the thermal conductivity of common metals is up to about 300W / m·K, and the graphite film is up to about 1000W / m·K, when the CPU power consumption is getting higher an...
