Problems solved by technology

[0004] The main chips of 5G folding screen mobile phones are generally installed on one side of the screen, which leads to uneven heat generation on both sides of the screen
However, the structure of the foldable graphite material is complex, the cost is high, and the graphite is brittle, easy to wear and tear, and the service life of the heat conduction component of the foldable screen is generally required to reach 200,000 times, and it can be folded 100 times per day to reach a service life of 5 years. This places extremely high requirements on the reciprocal folding, stretchability, and directional thermal conductivity of the heat-conducting member.

Abstract

The present application discloses a directional conductive tape, wherein the directional conductive tape is implemented as a belt-shaped fabric, wherein the tape-shaped fabric includes a certain heat-conducting area, a heat-absorbing area, and a heat-dissipating area, wherein the heat-absorbing area and The heat dissipation areas are respectively formed on both sides of the directional heat conduction area, and the weft of the directional heat conduction area of ​​the ribbon braid adopts a low heat conduction thread with a thermal conductivity of less than 10W / (m·K). The lines perpendicular to the extending direction of the strip-shaped fabric are weft threads, and the warp threads of the strip-shaped fabric adopt directional heat-conducting threads.

Description

technical field [0001] The invention relates to a thermally conductive material, in particular to a directional conductive tape. Background technique [0002] The transmission rate of 5G network can reach 10Gbps. The data reception and processing capacity of terminal mobile phones is 10 to 100 times that of 4G. The reception, processing, and transmission of massive data have sharply increased the computational load of various chips such as radio frequency chips, baseband chips, CPUs, and neural network chips, resulting in a sharp increase in chip power consumption, which in turn increases heat generation. [0003] Folding screens are currently a hot spot in the research and development of electronic screens. The screens are combined to form a certain size, which is easy to carry, and when opened, it becomes a larger display device. For example, the folding screen currently popular in the market can be folded to form a screen of a mobile phone, and can be unfolded to form a...
