Each latitudinal strand unit has a single latitudinal strand extending in a first direction. Each longitudinal strand unit has at least two longitudinal strands extending in a second direction different from the first direction, with the longitudinal strands passing over and under the latitudinal strand units and twisting densely in the second direction to form a plurality of crossing points between the longitudinal strands because of the twisting arrangement. The twisting arrangement of the longitudinal strands prevents unnecessary spaces formed between any two adjacent longitudinal strand units, improves the capillary phenomenon of working fluid within the vapor chamber unit, and facilitates the phase transition of the working fluid, thereby attaining the effect of dissipating heat quickly.

  • Patent number: 11566355
    Abstract: A braiding apparatus includes a platform, a base plate, a core unit, a transmission unit, a track assembly, and strand carriers. The track assembly is divided into two braiding track groups each provided with transmission discs. The transmission discs of both braiding track groups are sequentially connected to define two braiding routes. The strand carriers shuttle on both braiding routes respectively and incessantly. Two intersection points are defined when the two braiding routes intersect. Accordingly, carrier strands fed by the strand carriers are wound around a core strand fed by the core unit while shuttling incessantly and are interwoven with each other while passing through the two intersection points during the incessant shuttling motion, thereby wrapping a multi-convolutional braided layer around the core strand to complete a rope. Each convolution of the braided layer has two crossing points, which increases the practicability of the rope.
