Description

Technical Field

The invention relates to the technical field of electronic equipment, in particular to a mobile phone with a workstation function, a heat dissipation device of the mobile phone and a method for switching working states of the mobile phone.

Background

With the development of science and technology, mobile phones gradually become computing centers, and in a normal working scene, the mobile phones can be used as computing hosts to replace traditional computer hosts, and the functions of the computer hosts are completed by connecting a display and input (such as a mouse, a keyboard and the like) equipment; all software installed on the original computer host is installed on the mobile phone, and all calculation tasks completed by the original computer host are completed. And real mobile office is realized. At this time, the working mode of the mobile phone can be called as a workstation working state, which is different from a normal handheld working state.

The system chip of the mobile phone can release a large amount of heat when running at full power, and the mobile phone is generally in a down-conversion running state for the following two reasons: 1. different from the situation that electronic equipment with larger volume (such as a desktop computer) has sufficient space and structure for heat dissipation, the mobile phone has limited volume and space, cannot fully dissipate heat, and cannot design too many heat dissipation structures; 2. the surface temperature of the mobile phone is limited due to the fact that the mobile phone is a handheld device, and if the heat dissipation is performed fully on the structure, the heat inside the mobile phone is dissipated out through the shell, so that the surface temperature is easily too high, and the mobile phone is easily scalded by people at low temperature.

Therefore, in the conventional mobile phone heat dissipation device, if the surface temperature of the mobile phone is kept at a normal level when the mobile phone is held by a hand for normal use, the heat cannot be dissipated in time due to large heat productivity when the mobile phone is operated at full power as a workstation; if the surface temperature is kept at a normal level when the mobile phone is used as a workstation, the surface temperature is too high when the mobile phone is used by hand.
