Abstract

The invention provides a single-surface equilibrium phase transition suppressing heat radiating plate and mobile terminal equipment. One surface of the single-surface equilibrium phase transition suppressing heat radiating plate is a plane. The single-surface equilibrium phase transition suppressing heat radiating plate is internally provided with an arc-shaped heat superconducting pipeline area.The heat superconducting pipeline area is internally provided with an arc-shaped cyclic heat superconducting pipeline. The heat superconducting pipeline is a closed pipeline. The heat superconductingpipeline is filled with a heat transferring working medium. The surface of the single-surface equilibrium phase transition suppressing heat radiating plate is provided with a heat source adhering area. The heat source adhering area is arranged at the middle part of the heat superconducting pipeline area. The heat superconducting pipe is filled with the heat transferring working medium and is closed. The single-surface equilibrium phase transition suppressing heat radiating plate has advantages of high heat transferring rate, high temperature uniformity, and low thermal resistance between the heat superconducting pipeline and a board. The heat superconducting pipeline area and the heat superconducting pipeline are arc-shaped. Furthermore the heat source adhering area is arranged at the middle part of the heat superconducting pipeline area. The space in the mobile terminal equipment can be sufficiently used, and the heat generated by the heat source which adheres to the heat source adhering area can be transferred upwards and downwards.

Description

technical field [0001] The invention belongs to the technical field of heat transfer, and in particular relates to a single-sided plane phase transition suppressing radiator plate and a mobile terminal device. Background technique [0002] At present, the heat dissipation heat transfer plate for mobile phones is a structure in which small-diameter heat pipe components are flattened and then welded or glued to the substrate. Since the inner diameter of the heat pipe is less than 0.5mm, the thermal resistance of the heat dissipation heat transfer plate is relatively high. Both thermal power and efficiency cannot meet the heat increase requirements brought about by the increase of mobile phone functions. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a single-sided planar phase transition suppression cooling plate and mobile terminal equipment, which are used to solve the prob...
