Abstract

The invention discloses a mobile phone, and a refrigeration and heat dissipation device, a heat dissipation control method and a heat dissipation control system thereof, the refrigeration and heat dissipation device comprises a first heat dissipation structure arranged on a hand-held terminal body, and a backboard of the hand-held terminal body is provided with a via hole; the first heat dissipation structure comprises a heat pipe, a graphite heat dissipation sheet and a semiconductor refrigeration sheet; one end of the heat pipe is in contact with the heating unit of the handheld end body; one end of the heat pipe is provided with a through hole, the other end of the heat pipe is in contact with the graphite cooling fin, the semiconductor chilling plate is arranged at the through hole, awire of the semiconductor chilling plate is electrically connected with a battery of the mobile phone, the graphite cooling fin is arranged in the handheld end body, and the end, away from the heatingunit, of the heat pipe is in heat conduction connection with the semiconductor chilling plate; and the second heat dissipation structure is arranged on the workstation base. When the mobile phone isused in the form of a workstation, the semiconductor chilling plate and the cooling fan are used for accelerating heat dissipation, and timely heat dissipation in the state of the workstation is achieved.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a mobile phone, a cooling and heat dissipation device thereof, a heat dissipation control method and a system thereof. Background technique [0002] With the development of science and technology, mobile phones have gradually become computing centers. In normal working scenarios, mobile phones can be used as computing hosts instead of traditional computer hosts, and the functions of computer hosts can be completed by connecting monitors and input devices (such as mouse, keyboard, etc.) ; Install all the software installed on the original computer host on the mobile phone, and complete all the computing tasks completed by the original computer host. Realize true mobile office. At this time, the working mode of the mobile phone can be called a workstation working state, which is different from the normal handheld working state. [0003] The system chip of the mobile ...

AI Technical Summary

Problems solved by technology

[0003] The system chip of the mobile phone will release a lot of heat when it is running at full power. For the following two reasons, the mobile phone is generally in a state of reduced frequency operation: 1. Unlike larger electronic devices (such as desktop computers), there is sufficient space and structure For heat dissipation, the mobile phone has limited space and cannot fully dissipate heat, and at the same time cannot design too much heat dissipation structure; 2. Because the mobile phone is a handheld device, the surface temperature is limited. If the heat dissipation is too sufficient in the structure, it will cause internal heat It is emitted through the shell, which can easily cause the surface temperature to be too high, and cause low-temperature burns to people.

[0004] Therefore, if the existing mobile phone cooling device keeps the surface temperature of the mobile phone at a normal level when the mobile phone is in normal use, it will not be able to dissipate heat in time when it is running at full power as a workstation; If the temperature is maintained at a normal level, the surface temperature will be too high when the mobile phone is used in hand
